MATERIAL FOR SURFACE TREATMENT

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a material for surface treatment, capable of adsorbing polishing fluids in order to facilitate surface treatment such as grinding, polishing and cleansing to the surface to be processed. The present invention is also beneficial for structure designed for discharging particle waste from surface treatment, whereby the surface to be processed is prevented from damaged.

2. Description of the Related Art

Conventional arts associated with the present invention are related to, but not limited to, semiconductor industry, glass substrate industry, production of various smooth panels and the like. Most materials used for grinding, polishing, cleansing or similar applications in the industries abovementioned are usually a type of grinding plate, such as a polishing plate disclosed in U.S. Pat. No. 6,699,106, which is made into plate shape with ceramics or rigid alloys, wherein a plurality of grooves are carved onto the surface to form protrusions.

Such materials may as well be a nail polisher as disclosed in U.S. Pat. No. 5,658,184, including a base plate with a main surface, and a plurality of abrasive particles, wherein the abrasive particles are made of composite raw materials and attached to the main surface by applying adhesive.

The two conventional arts above use abrasive effect produced by interactive movement among the rigid polishing plate (base plate), protrusion (abrasive particles) and surface to be processed, in order to achieve the desired effect of surface treatment.

However, taking U.S. Pat. No. 6,699,106 as an example, transverse and vertical grooves intercross perpendicularly. The interactive movement between the polishing plate and the surface to be processed is presented perpendicularly against the carved grooves, whereby the particle waste is accumulated on lateral side of the e protrusions, thus unfavorable for discharging. Besides, after repetitive and numerous abrasions, the accumulated particle waste scratches and damage the surface to be processed. As for U.S. Pat. No. 5,658,184, the abrasive particles are attached by applying adhesive. The abrasive particles tend to detaches as a result of friction force in the process of surface treatment, causing the mix of the abrasive particles and particle waste, thereby scratching and damaging the surface to be processed.

Also in the process of grinding and polishing, polishing fluid is usually added between the polishing plate and the surface to be processed, in order to enhance the effect of grinding and polishing. However, the rigid polishing plate (base plate) lacks obvious effect of adsorbing liquid. Therefore, the polishing fluid must be continuously added to flush in the process of surface treatment, whereby most of the polishing fluid flows away directly and thus is unable to facilitate the surface treatment.

Additionally, most of the rigid polishing plate (base plate) only acts on flat surfaces, and inconvenient to be used on curved or shaped surfaces.

SUMMARY OF THE INVENTION

The present invention relates to a material for surface treatment, comprising a main body made of a soft material with capability of adsorbing liquid and a plurality of protrusions disposed and protruding on a surface of the main body, wherein each of the protrusions is in a shape of polygonal column, and each internal angle of the polygonal column is between 90 to 180 degrees. A gap lies in between each of the columns, wherein a tunnel is formed in web shape by the interconnection of the gaps. The main body and the protrusions are made of, but not limited to, artificial leather, polyurethane, resin or acrylic, whereby the main body and the protrusions thus possess flexibility, absorptivity, and are prevented from dropping dust waste.

The present invention has following advantages:

- 1. The protrusions are presented as polygonal columns, wherein each internal angle of the polygonal column is between 90 to 180 degrees. When the main body rubs against the surface to be processed, the polygonal column shape of the protrusions lower the accumulation of the particle waste, thereby aiding the particle waste to be discharged from the space among the protrusions.
- 2. The main body is capable of adsorbing liquid. In the process of surface treatment, the main body is allowed to efficiently adsorb polishing fluid such as the polishing agent, cleansing fluid or water, and the protrusions thereby scrape off extraneous matters on the surface to be processed by cooperating with the polishing fluid. Therefore, the present invention may be widely applied in grinding, polishing and cleansing industries or other businesses alike.
- 3. The main body is made of flexible material, wherein the shapes of the main body and the protrusions are allowed to change in accordance with the shapes of the surface to be processed while used on curved, angled or shaped surfaces, and thus widening the range of application.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, the present invention is a material for surface treatment, comprising a main body 10 and a plurality of protrusions 20 disposed on a surface 11 of the main body 10.

The main body 10 is made of a flexible material, chosen from at least one of artificial leather, polyurethane, resin or acrylic, with capability of adsorbing liquid, wherein the structural form of the main body 10 includes, but not limited to, a plate, a block, a weaved object or a felt.

The protrusions 20 vertically protrude from the surface 11 of the main body 10, wherein each protrusion 20 is presented as a polygonal column, and each internal angle 21, of θ degrees, on the periphery of the column is between 90 to 180 degrees, as shown in FIG. 2. In addition, a gap 22 lies in between each of the protrusions 20, wherein the interconnection of the gaps 22 forms a web shape tunnel 30.

The protrusions 20 are mainly made of at least one of polyurethane, resin or acrylic. The materials above make the main body 10 and the protrusions 20 possess flexibility, absorptivity and prevented from dropping dust waste.

Moreover, as shown in FIG. 3, the protrusions 20 and the main body 10 may be made of same material and integral. Or, as shown in FIGS. 7-8, the protrusions 20 and the main body 10 may be made of different materials, and the protrusions 20 are attached to the surface 11 of the main body 10 by adhesion or other methods for combination.

The protrusions 20 protrude from the surface 11 of the main body 10, thereby increasing the facial abrasive force of the main body 10. As shown in FIG. 4, the adsorptivity of the main body 10 helps to adsorb a polishing fluid 91, such as polishing agent, into the main body 10 and the gaps 22 between the protrusions 20, whereby the polishing fluid 91 is allowed to be kept in the main body 10 to be prevented from dropping and flowing away.

As shown in FIG. 5, in the process of surface treatment, the protrusions 20 with the polishing fluid 91 scrape off extraneous matters or uneven portions on a surface to be processed 90 and flatly grind, thereby completing the process of cleansing, grinding or polishing the surface. The extraneous matters produced by grinding, such as particle waste 92, are carried away by the protrusions 20 or fall into the gaps 22 between the protrusions 20, thereby prevented from attaching on the surface of the object grinded or polished, in order to avoid re-scratching the surface to be processed 90.

In addition, the polishing fluid adsorbed by the main body 10, such as polishing agent, cleansing fluid or water, are released between the protrusions 20 and the surface to be processed 90 in the process of surface treatment, thereby optimizing the effect of cleansing, grinding and polishing, and also helpful for carrying away the extraneous matters such as the particle waste 92 and cleansing the surface to be processed 90. The polishing fluid 91 does not need to be added repeatedly, whereby the utilizing rate of the polishing fluid 91 is increased.

Moreover, as shown in FIG. 6, after the particle waste 92 produced from grinding fall into the gaps 22 between the protrusions 20, the moving force of the main body 10 motivates the particle waste 92 to move in the tunnel 30 formed by the gaps 22, whereby the particle waste 92 is discharged from the main body 10. Based on the polygonal-columnar shape of the protrusions 20, the θ degrees of all the internal angles 21 on the periphery is between 90 to 180 degrees. Taking the hexagonal columns shown in FIGS. 1-6 for example, the particle waste 92 is allowed to pass the gaps 22 between each of the protrusions 20, and thus moving in the interconnected tunnel 30. As shown in FIG. 2, the degrees of the internal angles 21 are designed to make adjacent gaps 22a, 22b and 22c intercross with an angle between 90 to 180 degrees. When the particle waste 92 in the gap 22a moves toward the marked internal angle 21a, the degrees of the internal angle 21a is favorable for inducing the particle waste 92 to flow toward the gap 22b and 22c, thereby lowering the chance of the particle waste 92 stuck on lateral side of the protrusions 20, and enabling the particle waste 92 to be discharged along the tunnel 30.

Furthermore, the polishing fluid 91 released by the main body 10 not only enhances the effect of grinding, polishing and cleansing, but also helps to carry the particle waste 92 into the gaps 22 after mixed with the particle waste 92, and accelerates the moving and discharges of the particle waste 92 through the tunnel 30.

As shown in FIG. 7, because the main body 10 is made of flexible material with capability of bending and deforming, when the shape of the surface to be processed 90 is not a flat surface, the main body 10 is allowed to bend and deform in accordance with the shape of the surface to be processed 90, in order to reduce the formation of gaps or blind spots, thereby increasing the evenness of grinding, polishing and cleansing.

As shown in FIGS. 8-9, to achieve objectives of various applications, the protrusions 20 and the main body 10 are allowed to be made of different raw materials, while the protrusions 20 are attached to the surface 11 of the main body 10 by methods of combining such as adhesion. Therefore, with the combination of protrusions 20 and the main body 10 with different hardness, products with different textures from grinding and polishing are allowed to be produced.

Although a number of best embodiments of the invention have been described for purposes of illustration, various modifications and enhancements by skilled people may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims, and all modifications and enhancements without departing the spirit of the invention are included within the scale of the claims.
