Claims14
A woven-backed vinyl decorative-covering having a starchy-PVA prepaste adhesive applied to a scrim portion of the woven back to provide retention of adhesive capacity after soaking, slip and strippability, wherein said adhesive comprises a starch, an aqueous emulsion of a polyvinyl acetate-containing polymer selected from the group consisting of polyvinyl acetate homopolymers and copolymers of vinyl acetate with ethylene or derivatives of acrylic or maleic acids, at least one humectant, a filler, at least one defoamer, a preservative and a dispersing agent.
A woven-backed vinyl decorative covering having a starchy-PVA prepaste adhesive applied to a scrim portion of the woven back to provide retention of adhesive capacity after soaking, slip and strippability, wherein said adhesive consists essentially of a modified waxy maize starch, an aqueous emulsion of a polyvinyl acetate homopolymer, a humectant comprising sugar and urea, a filler comprising an aluminum silicate, a defoamer comprising a glycol and an oil, a preservative comprising a bacteriostat and a fungicide, and a dispersing agent comprising a sodium salt of a polymerized alkyl naphthalene sulfonic acid.
The covering of claim 20 wherein the modified waxy maize ids present at approximately 36 percent;
- the polyvinyl acetate homopolymer is present at approximately 19 percent;
- the aluminum silicate is present at approximately 23 percent;
- the glycol-type defoamer is a polypropylene glycol present at approximately 0.5 percent;
- the oil-type defoamer is a mineral oil present at approximately 0.5 percent;
- the bacteriostat contains 1,2-dibromo-2,4-dicyanobutane;
- the fungicide contains 2-(4-thiazolyl)benzimidazole, said percents being by weight exclusive of any free water, and the vinyl is polyvinyl chloride.
A starchy-PVA prepaste adhesive comprising a starch, an aqueous emulsion of a polyvinyl-acetate-containing polymer selected from the group consisting of polyvinyl acetate homopolymers and copolymers of vinyl acetate with ethylene or derivatives of acrylic or maleic acids, at least one humectant, a filler, at least one defoamer, a preservative and a dispersing agent.
A method for preparing woven-backed vinyl decorative-covering with starchy-PVA prepaste adhesive comprising contacting a scrim portion of an appropriate woven-backed vinyl decorative-covering with a starchy PVA prepaste adhesive comprising a starch, an aqueous emulsion of a polyvinyl acetate-containing polymer, at least one humectant, a filler, at least one defoamer, a preservative and a dispersing agent under conditions including roller coating and hot box drying such that the woven-backed vinyl decorative-covering with starch-PVA prepaste adhesive is prepared.
A method for using woven-backed vinyl decorative-covering with a starchy-PVA prepaste adhesive comprising a starch, an aqueous emulsion of a polyvinyl acetate-containing polymer, at least one humectant, a filler, at least one defoamer, a preservative and a dispersing agent, said method comprising steps of wetting the adhesive of said covering and contacting the wet adhesive of said covering with a surface under conditions such that said covering is applied to the surface.
