Abstract
Decorative sheet type covering material and process for making same. The material has a substrate, a foamed vinyl plastic layer over the substrate, a thin unfoamed smooth plastic layer over the foamed layer, a metal layer over the smooth layer and a wear layer over the metal layer.
Claims21
Decorative sheet type covering material comprising:
- a. a substrate;
- b. a foamed vinyl plastic layer adhered to said substrate;
- c. an unfoamed smooth plastic layer of cured PVC plastisol or organosol adhered to said foamed layer;
- d. a metal layer adhered to said smooth layer;
- and
- e. a wear layer comprising cured polyurethane or cured PVC plastisol or organosol over said metal layer.
3 more elements
Decorative sheet type covering material comprising:
- a. a seal coated asbestos felt substrate;
- b. a chemically foamed layer of cured PVC plastisol or organosol ahdered to said substrate, said foamed layer being between about 5 and about 100 mils thick in its unembossed portions;
- c. an unfoamed smooth layer of cured PVC plastisol or organosol between about 1 and about 4 mils thick adhered to said foamed layer;
- d. a discontinuous layer of metal less than about 0.5 mil thick adhered to said smooth layer.
- e. a layer of cured latex less than about 1 mil thick adhered to said metal layer and having a decorative design printed thereon;
- and
- f. a wear layer between about 7 and about 20 mils thick adhered to said latex coated metal layer, said wear layer comprising cured PVC plastisol or organosol.
4 more elements
A process for making decorative sheet type covering material which comprises the steps of:
- a. adhering a foamable layer of vinyl plastic to a substrate and gelling said layer;
- b. adhering a nonfoamable layer of PVC plastisol or organosol to said foamable layer and gelling the nonfoamable layer;
- c. applying continuous metal layer over the gelled nonfoamable layer;
- d. applying a wear layer comprising polyurethane or PVC plastisol or organosol over the metal layer;
- and
- e. heating the material sufficiently to expand the foamable layer and cure the foamed layer, the nonfoamable layer and the wear layer.
3 more elements
A process for making decorative sheet type covering material which comprises:
- a. adhering a layer between about 2 and about 30 mils thick of foamable plastic comprising PVC plastisol or organosol and blowing agent to a substrate comprising seal coated asbestos felt and gelling said foamable layer at a temperature between about 150.degree. and about 350.degree. F for a time between about 0.1 and about 5 minutes;
- b. adhering a smooth nonfoamable layer of PVC plastisol or organosol between about 1 and about 4 mils thick to the foamable layer and gelling the nonfoamable layer at a temperature between about 150.degree. and about 350.degree. C for a time between about 0.1 and about 5 minutes;
- c. applying a pattern of suppressant ink to the gelled nonfoamable layer whereby the suppressant ink penetrates through said non foamable layer and into the foamable layer;
- d. applying a continuous unsupported metal layer less than about 0.5 mil thick to the non foamable layer;
- e. applying a smooth layer of latex less than about 1 mil thick to the metal layer and dring said latex layer;
- f. applying a printed ornamental design to the surface said latex layer;
- g. applying a wear layer between about 7 and about 20 mils thick comprising PVC plastisol or organosol over said printed latex layer;
- and
- h. curing the material at a temperature between about 300.degree. and about 450.degree. F for a time between about 1 and about 5 minutes to thereby cure the wear layer and nonfoamable layer and expand and cure the foamable layer.
