摘要:
A method for making a surface covering is disclosed which includes providing a surface covering having a backing layer, a foamable layer, and a design layer, wherein the design layer includes a portion of a pattern printed with at least one retarder composition. A wear layer is then provided on the design layer and the wear layer is cured. The foamable layer is thereby expanded to form a foam layer, and the pattern printed with at least one retarder composition is chemically embossed. The cured product is subsequently cooled to ambient temperature and then the top surface of the wear layer is subjected to a sufficient temperature to soften the wear layer. After being softened the wear layer is mechanically embossed with a surface texture, the embossed surface texture is set in the wear layer, and a top coat may then be provided on the embossed set wear layer. A surface covering having the various features described above is also disclosed. Preferably, the surface covering and the method for making the surface covering have a natural wood, stone, marble, granite, or brick appearance wherein the design layer includes one or more joint or grout lines created with at least one retarder composition and the wear layer is mechanically embossed with the surface texture of a wood, stone, marble, granite, or brick surface.
摘要:
Ultra-violet stabilized polyvinyl resins, such as polyvinyl chloride, are disclosed. The ultra-violet stabilized polyvinyl resins comprise polyvinyl resins and a stabilizer comprising a benzylidene malonic ester of 1,2,2,6,6-pentamethylpiperidinol or its derivatives. The stabilizer can be added to or dispersed within the polyvinyl resins prior to any objects or articles being formed from the resins. Also disclosed is a method to impart ultra-violet stabilization to polyvinyl resins which includes the step of adding to or dispersing within the polyvinyl resins, a stabilizer comprising a benzylidene malonic ester of 1,2,2,6,6-pentamethylpiperidinol or its derivatives. The invention further includes the addition of an ultra-violet absorber such as ethane diamine, n-(2-ethoxyphenyl)-n.sup.1 -(4-ethyl phenyl) to the polyvinyl resin composition.
摘要:
This invention is directed to a resilient, flexible surface covering that has a wear surface that meets the highest standards of stain, mar, scuff, and soil resistance and a method of making the same. The improved resilient surface covering comprises (a) a resilient support surface; and (b) a resilient wear surface adhered to the resilient support surface, the resilient wear surface comprising an underlying wear layer base coat and an overlying wear layer top coat adhered to the wear layer base coat, the wear layer base coat comprising a flexible, thermoset, polymeric composition having a flexibility such that the wear layer base coat passes a 1 inch mandrel diameter face out mandrel bend test when applied at a nominal dry film thickness of 1.0 mil over a flexible 80 mil underlying substrate, the wear layer top coat comprising, a hard, thermoset, UV-curable blend of acrylic or acrylate monomers, the wear layer top coat having a glass transition temperature of greater than 50.degree. C. The present invention is also directed to separately or in combination with the improved wear surface, a resilient surface covering that has a strengthening layer that provides improved strength, toughness, resistance to breakage, especially resistance to tearing, and resistance to deformation, especially resistance to indentation and sliding gouging, and a method of making the same. The improved strengthening layer resilient surface covering comprises (a) a resilient support surface comprising an unfoamed strengthening layer comprising a vinyl resin and a polymerized, cross-linked monomer, with the proviso that, the strengthening layer is not disposed between two foam layers; and (b) a resilient wear surface adhered to the resilient support surface.
