In general, industrial flooring is typically composed of a vinyl composition tile (VCT), sheet vinyl, terrazzo, rubber, linoleum, honed marble or granite, and unglazed ceramic. These materials have proven to be highly popular flooring choices because of their durability and ease of maintenance. However, in order to sustain an aesthetically appealing and durable floor, these industrial flooring materials need to be cleaned often and properly maintained. For example, each of these materials requires a protective coating or floor finish that is designed to yield a high gloss after initial application and exceptional scratch, scuff, and/or chemical resistance.
Dirt and debris are very abrasive when left on a floor surface. Constant foot traffic coupled with the abrasive materials leads to scratching/gouging of the floor and, as a result, the floor loses its gloss and overall visual appeal. To maintain the flooring, a conventional floor care process is often undertaken, such as the process depicted in
A cleaning process is then typically performed daily or every other day using a spray cleaner or scrubbing solution to remove dirt and debris from the floor. In addition to cleaning, the floor is typically buffed to remove light scuffs and dirt from the surface. Buffing is typically performed using a nylon or natural hair pad and a low or high speed machine. The floor is also burnished on a daily basis to restore gloss to the floor finish. This is performed in a dry application using a high or ultra-high speed machine (1000-3000 rpm) with the use of nylon and natural hair pads.
Periodically, a deep-scrub and recoat process may be performed to remove heavy scuff marks and mild wear and soiling from the finish. This process typically removes one to two coats of finish, and these coats are then replaced. This is most often performed using a low speed machine, spray solution, and scrubbing pad. The above described process may be repeated multiple times throughout the year.
The above described process is costly and labor intensive. Additionally, stripping chemicals possess a strong odor, are potentially hazardous materials (e.g., slip-fall hazard, corrosive to eye and skin), and may damage the floor and equipment used. Furthermore, stripping may be disruptive to business, where hospitals may have to close rooms or hallways for maintenance, and retail stores may have to close aisles for 24 hours.
Currently, there is a need in the art for the development of a new cleaning process that reduces the steps and cost to maintain an aesthetically appealing and durable floor.
In some aspects, the present disclosure addresses the aforementioned drawbacks by providing a floor protection and cleaning system (also referred to herein as a “strip free” system) that eliminates multiple steps from conventional floor cleaning processes, while maintaining aesthetically appealing and durable floors. As will be described, the present disclosure provides compositions and methods for advantageously removing the annual stripping step associated with conventional floor maintenance. This results in a significant reduction in material and labor costs for maintaining the durability and aesthetic appeal of industrial flooring. Furthermore, eliminating the annual stripping step reduces disruption of businesses, and reduces the amount of times workers may be exposed to potentially hazardous stripping chemicals. In some embodiments, the remover solution may advantageously include a low volatile organic compound (VOC) content or be substantially free of volatile organic compounds, thereby providing an environmentally-friendly product with reduced impact on air quality in the surrounding environment.

As indicated by process block 306, the floor finish composition 204 is then maintained by regularly cleaning and/or revitalizing the floor finish composition 204, for example, by regularly removing dirt and debris from the floor surface. In some aspects, step 306 includes applying a cleaning solution (e.g., neutral, alkaline, or acidic) to the floor finish composition 204 and scrubbing the surface, for example, using a mop or an abrasive pad 202 coupled to a floor cleaning machine. Occasionally a remover solution 206 is applied to remove at least a portion of the floor finish composition 204 during the cleaning and revitalizing step 306. Suitable abrasive pads 202 for use during the cleaning and revitalizing step 306 may have a grit between 500-3000.
Overtime, the floor finish composition 204 may become susceptible to heavy abrasions and/or stains. The heavy abrasions and/or stains may be removed by scrubbing and re-coating the floor finish composition 204, as indicated by process block 308. In some aspects, step 308 includes applying a remover solution 206 and scrubbing/cleaning the floor finish composition 204 to remove at least a portion of the floor finish composition 204. Scrubbing/cleaning the floor surface may include using an abrasive pad 202 coupled to a floor cleaning machine.

After a portion of the floor finish composition 204 has been removed, one or more new coats of the floor finish composition 204 may be applied to the floor surface. In some aspects, the number of re-coats includes a single coat of the floor finish composition 204. In other aspects, the number of re-coats of the floor finish composition includes two coats, or three coats, or four coats. Process step 308 may be repeated a number of times throughout a year, for example, the step of scrubbing/cleaning the floor finish composition 204 and re-coating the floor surface may be performed one time a year, or two times a year, or three times a year, or four times a year, or five times a year.
Advantageously, by using the method 300 in combination with the floor finish composition 204 and remover solution 206 of the present disclosure, the process step of annually stripping the floor finish composition may be eliminated. This results in a significant reduction in material and labor costs for maintaining the durability and aesthetic appeal of industrial flooring. Furthermore, eliminating the annual stripping step reduces disruption of businesses, and reduces the amount of times workers may be exposed to potentially hazardous stripping chemicals.

In some aspects, the one or more alkali soluble resin may influence the coatability or spreadability of the floor finishing composition 204 onto a surface. For example, one of the challenges associated with conventional floor finish compositions is the tendency for the composition to clump or adhere to the pad or mop being used to spread the composition over the surface. It is a recognition of the present disclosure that material properties of the alkali soluble resin may be tuned or leveraged to prevent undesirable results associated with deposition of the floor finish composition on the surface, such as clumping and adhesion to a pad or mop.

The acid number may be determined using various methods known to those skilled in the art, for example, the acid number may correlate to an amount of potassium hydroxide for neutralizing one gram of the alkali soluble resin, as would be readily understood by those skilled in the art.
In some aspects, the glass transition temperature of the alkali soluble resin may influence the floor finish composition 204 in accordance with the present disclosure to achieve improve performance properties, such as clumping resistance and reduced drag during deposition.

The floor finish cleaner/remover does not contain glycol ethers. The floor finish cleaner/remover does not contain ammonia. The floor finish cleaner/remover does not contain monoethanolamine. The floor finish cleaner/remover does not contain sodium hydroxide.
Referring now to Table 10, a list of numerical entries are provided for the floor finish cleaner/remover solution of Example 2A:
Another floor finish cleaner/remover solution was formulated as shown in Table 11. The floor finish cleaner/remover was a hazy single phase solution. The floor finish cleaner/remover does not separate into two phases upon mixture with water and allowed to stand. The floor finish cleaner/remover does not contain solvents.
Referring now to Table 12, a list of numerical entries are provided for the floor finish cleaner/remover solution of Example 2B:
Based on testing of floor finishes comparable to the floor finishes of Examples 1A, 1B and 1C, we envision that four coats of any of the floor finishes of Examples 1A, 1B and 1C will have gloss parity to eight coats of a commercially available floor finish after ten burnishings of the floor finishes of Examples 1A, 1B and 1C over a ten week time period. Without intending to be bound by theory, it is believed that, among other things, alkali soluble acrylic resins such as the Joncryl® ECO 75 used in the floor finishes of Examples 1A, 1B, 1C, and 1D improve removability while maintaining high performance of durability. Also, we envision that there is a relationship between the use of N,N-dimethyl-9-decenamide and 2-(2-aminoethoxy)ethanol in the floor finish cleaner/remover of Example 2 that provides the unexpected result of removing the floor finishes of Examples 1A, 1B and 1C.
The floor finishes of Examples 1A, 1B, 1C, and 1D showed good water, alcohol, peroxide, and quat disinfectant cleaner resistance.
The floor finishes of Examples 1A, 1B, 1C, and 1D are parity or better to commercially available floor cleaners in cleaning tests.
The floor finishes of Examples 1A, 1B, 1C, and 1D and the floor finish cleaner/remover of Example 2 are compatible with substrates such as vinyl composition tile, sheet vinyl, terrazzo, rubber, linoleum, honed marble or granite, and unglazed ceramic.
Floor finish cleaner/removers similar to Example 2 were formulated with varying levels of 2-amino-2-methyl-1-propanol containing 5% added water (AMP-95™), monoisopropanolamine (MIPA), and 2-(2-aminoethoxy) ethanol (DGA) as shown in

Referring to
In the modified version of ASTM D1792 used herein, the dwell time of applying the remover/cleaner/stripper solution is reduced to 10 seconds from the standard one minute, 30 mL of solution is used in each test and the application pad is not soaked with the remover/cleaner/stripper solution, and the cure time is increased to 100 hours at 100° F. from the standard of 48 hours.
The remover solution of Example 2B at 1:55 dilution performs better on all tested floor finishes than all other floor cleaners tested, such as GP Forward at 1:128 dilution, Buckeye Blue at 1:128 dilution, Spartan Tribase at 1:128 dilution, UHS at 1:128 dilution, and Prominence at 1:128 dilution.
The present disclosure has described one or more non-limiting example embodiments, and it should be appreciated that many equivalents, alternatives, variations, and modifications, aside from those expressly stated, are possible and within the scope of the invention.
