Abstract
A flooring material (1) comprises a base portion (2) having a coating portion (3) which imparts improved stain resistance to the flooring material (1) and is positioned in contact with an upper surface of the base portion (2). The coating portion (3) creates an upper surface of the flooring material (1). A particulate material (6) is embedded in the coating material (3) and at least partially penetrates the base portion (2). The particulate material (6) provides a roughened effect to the upper surface of the flooring material (1) and protects the coating from wear. The coating (3) merges into the base portion (2) where they meet at joint (4) to form a stratified portion (5).
Claims56
A flooring material comprising a base portion, a coating portion imparting improved stain resistance to the flooring material being positioned in contact with an upper surface of the base portion and creating an upper surface of the flooring material, and a first particulate material embedded in the coating portion and at least partially penetrating the base portion to provide a roughening effect of the upper surface of the flooring material for enhanced slip resistance and protection from wear.
A method of making a flooring material comprising a base portion, a coating portion imparting improved stain resistance to the flooring material and positioned on an upper surface of the base portion to form an upper surface of the flooring material and first particulate material embedded in the coating portion and at least partially penetrating the base portion to provide a roughening effect to the upper surface of the flooring material for enhanced slip resistance and protection from wear, the method comprising the steps of:
- a) mixing together the components of the base portion;
- b) spreading the mixed components of the base portion on a surface;
- c) applying at least one first dressing of components of the coating portion in powder form to the components of the base portion to at least partially penetrate the base portion;
- d) applying at least one dressing of a first particulate material to the components of the coating portion in powder form;
- e) heating the base portion and said at least one first dressing to cause the components of the coating portion in powder form to form a film.
A floor covering material comprising a PVC layer and having aggregate embedded in the material for providing surface roughness wherein the material incorporates a barrier layer of polymeric material other than PVC fused into the upper surface of the PVC layer, the aggregate being exposed at the surface of the barrier layer.
A method of producing a floor covering material comprising
- (a) spreading a PVC plastisol on a substrate,
- (b) distributing over the surface of the plastisol a powder of a film forming, heat fusible polymeric material other than PVC and a particulate aggregate material, and
- (c) effecting heating to fuse the plastisol and convert the powder into a film,
- steps (b) and (c) being effected such that aggregate is exposed at the surface of the film.
