Abstract

A non-slip plastics floor material having high durability and comprising a polyvinyl chloride matrix layer having synthetic resin particles dispersed therein throughout its entire thickness. The resin particles have a softening point higher than the processing temperature of the resin composition forming the matrix layer and higher abrasion resistance than the matrix layer. Some of the resin particles are exposed from the surface of the matrix layer.

Claims

1. A non-slip floor material characterized in that the floor material comprises a polyvinyl chloride matrix surface layer having dispersed therein throughout its entire thickness synthetic resin particles selected from the group consisting of acrylic resin, polyurethane, nylon resin, polyester and ABS resin in an amount of 3 to 30 wt.% of the entire weight of the matrix layer, the resin particles being 100μ

to 1 mm in particle size and having a softening point higher than the processing temperature of the resin composition forming the matrix layer and higher abrasion resistance than the matrix layer, a quantity of the resin particles being exposed from the surface of the matrix layer, wherein the difference in abrasion weight loss between the matrix layer and the particles is at least 50 mg and the difference in wear thickness between the matrix layer and the particles is at least 0.01 mm when the floor material is subjected to 1000 cycles of a Taber abraser apparatus at a loading of 500 g on each wheel, the wheels having S-33 sandpaper attached to the surfaces thereof.

2. A floor material as defined in claim 1 wherein the resin particles are in the range of 140 to 150μ

in particle size.

3. A floor material as defined in claim 1 wherein the matrix layer is about 0.1 to about 5 mm in thickness.

4. A floor material as defined in claim 3 wherein the matrix layer is about 0.3 to about 3 mm in thickness.

5. A floor material as defined in claim 1 which further has a backing laminated to the rear surface thereof.

6. A floor material as defined in claim 5 wherein the backing is a sheet of one of foamed plastics, non-foamed plastics, a woven fabric of one of organic and inorganic fibers, and a nonwoven fabric of one of organic and inorganic fiber.

7. A floor material as defined in claim 5 wherein the thickness of the floor material including the backing is about 1 to about 10 mm.

8. A floor material as defined in claim 7 wherein the thickness of the floor material including the backing is about 2 to about 5 mm.

9. A floor material as defined in claim 1, wherein the resin particles are of polyurethane.

10. A floor material as claimed in claim 5, wherein the backing is a sheet of foamed plastics.
