2. Description of Related Art
In early days, flooring materials mostly come from natural stone or ceramic products. These materials are costly and may cause destruction of the natural environment. As a substitute, manufacturers gradually developed flooring tiles made of plastic materials, namely PVC floor tiles.
Over the recent years, along with the rapid change of the economic society, the demands of consumers become higher and higher, but meanwhile they are innately influenced by the natural environment, and value designs in connection with the nature. To cater to the new demands of consumers, companies in the building industry are once again beginning to invest in the market of natural stone building materials.
In the market of natural stone building materials like cobblestone tiles, massive amount of stone materials shall be prepared before production. This causes considerable destruction to the natural environment. Meanwhile, it takes a long time to prepare the stone materials, and the manufacturers need to pay attention that the stones must meet specific application criterions, such as sizes, colors, surface conditions etc. The manufacturing process is also time-consuming and costly. Therefore, the final price of the stone building materials is staying at a high level.
In view of the aforementioned problems, the present invention aims to make some improvements to reduce the cost, price and manufacturing difficulty by providing a low-cost and environment-friendly decorative building material and its manufacturing method characterized by easy production and non-use of natural stones.
The present invention overcomes the aforementioned problems from two aspects. Firstly, in the aspect of building materials, it is a low-cost and environment-friendly decorative building material (100), comprising a substrate (1); multiple decorative colloids (2) of various shapes and sizes distributed on and adhered to the top surface of the substrate (1); solidified base layers (3) distributed respectively in correspondence with the decorative colloids (2), and located on the top surface of the decorative colloids (2) to shape the decorative colloids (2) after primary sintering; and protective layers (4) of various colors and patterns, distributed respectively in correspondence with the decorative colloids (2), configured on the surface of the solidified base layer (3) through spray printing, to shape and color the decorative colloids (2) after secondary sintering; said solidified base layers (3) and protective layers (4) both contain glaze powder (5); while said protective layers (4) further contain glue (6) that can fix the aforementioned glaze powder (5) on the surface of the solidified base layers (3).
Secondly, in the aspect of manufacturing method, there are the following steps: Step 1 (I): A substrate (1) is obtained; Step 2 (II): Decorative colloids (2) of various shapes and sizes are distributed on and adhered to the top surface of the substrate (1) to form a rough blank (A); Step 3 (III): Inside a sealed space, glaze powder (5) is sprayed on the top surface of the rough blank (A); Step 4 (IV): After spraying the glaze powder (5), the top surface of the rough blank (A) is blown to remove and recycle the glaze powder (5) not falling on the top surface of the decorative colloids (2), and now a rough semi-finished product (B) is formed; Step 5 (V): The rough semi-finished product (B) undergoes a primary sintering, and after the sintering, a solidified base layer (3) is formed on the top surface of each decorative colloid (2), and now a refined semi-finished product (C) is formed; Step 6 (VI): Inside a sealed space, a spray printing machine is used to spray the aforementioned refined semi-finished product (C) to add a protective layer (4) on each of the decorative colloids (2), and now a semi-finished product (D) is formed; and Step 7 (VII): Wait for the protective layer (4) to dry; when the protective layer (4) becomes dry, the semi-finished product (D) undergoes a secondary sintering; and after the secondary sintering, a low-cost and environment-friendly decorative building material (100) is now finished.
Comparing to the existing techniques, the present invention has the following efficacies:
Through a combination of decorative colloid (2), solidified base layer (3), and protective layer (4), the present invention realizes its goal to reduce the cost, price and manufacturing difficulty. The coloring method using spray printing can simplify the overall processes and meet diversified and customized application needs of consumers. The present invention can perfectly imitate stone decorative building materials to minimize destruction of the environment and substantially enhance industrial applicability.
Apart from its flexible applications to meet diversified consumer needs, the manufacturing method of the present invention further produces a unique low-cost and environment-friendly decorative building material. More importantly, it reduces manufacturing cost and time to enable fast applications by the consumers.
As the present invention forms a protective layer (4) through spray printing, it can satisfy more diversified application needs of the consumers.
The aforementioned combination of decorative colloid (2), solidified base layer (3), and protective layer (4) can reduce the cost, price and manufacturing difficulty of the low-cost and environment-friendly decorative building material (100) and can obtain the texture and sense of quality of natural stones without actually using natural stones.
Secondly, based on the combination of glaze powder (5) and glue (6), the spray printing method can simplify the overall manufacturing processes of low-cost and environment-friendly decorative building material (100), and can realize customization, fast production, as well as easy control to reduce the reject ratio.
The combined maximum thickness of the solidified base layers (3) and the protective layers (4) is 6 mm. Various options of the thickness of the solidified base layer (3) and protective layer (4) can be freely selected by consumers to meet their specific needs for safety and comfort.
The aforementioned substrate (1) is one of the followings: ceramic plate and ceramic tile. When said substrate (1) is a ceramic plate, its thickness range is 3 mm˜6 mm; while when said substrate (1) is a ceramic tile, its thickness range is 5 mm˜10 mm. To meet diversified consumer needs and applications, the substrate (1) can be of various materials and various thicknesses. Therefore, the present invention can have a wider application range, with no problem of inapplicability.
The aforementioned decorative colloid (2) contains isobornyl acrylate, 1,6-hexanediol diacrylate, tetrahydrofurfuryl acrylate, multifunctional acrylate, 2-hydroxy-2-methylpropiophenone, diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide, and additive.
The weight percentage of the aforementioned isobornyl acrylate is 5˜15; the weight percentage of the aforementioned 1,6-hexanediol diacrylate is 10˜20; the weight percentage of said tetrahydrofurfuryl acrylate is 20˜30; the weight percentage of the aforementioned multifunctional acrylat is 20˜30; the weight percentage of the aforementioned 2-hydroxy-2-methylpropiophenone is 1˜5; the weight percentage of the aforementioned diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide is 1˜10; and the weight percentage of the aforementioned additive is 1˜10.
Through adoption of the aforementioned decorative colloid (2), the present invention can perfectly imitate stones, with sufficient hardness and good resistance to repeated high-temperature heating. Moreover, it will not fall easily apart from the top surface of the substrate (1).
Through implementation of this manufacturing method, the production becomes very flexible.
