Abstract
Waterproof engineered floor and wall planks have a wear layer and an underlayer about an extruded dust and plastic composite core.
Claims22
An engineered waterproof plank comprising:
- (a) a wear layer adhered to a top surface of a waterproof core;
- (b) a first waterproof adhesive layer bonding the wear layer to the top surface of the waterproof core;
- (c) the waterproof core comprising an extruded dust and plastic composite;
- (d) the plank having a first edge with a groove extending laterally into the waterproof core and a second opposite edge with a lateral protrusion from the waterproof core, wherein the groove and protrusion have profiles shaped to form a click-lock edge fastening system.
(canceled)
(canceled)
The plank of claim 21 wherein the waterproof core further comprises less than 10% of additives selected from the group consisting of anti-oxidation agents, stabilizers, colorants, anti-fungus agents, coupling agents, reinforcing agents and lubricants.
An engineered rectangular waterproof plank comprising:
- (a) a wear layer of decorative vinyl adhered to a top surface of a waterproof core by a hot melt adhesive;
- (b) a cover layer over the wear layer, said cover layer selected from the group consisting of melamine resin with aluminum oxide and polyurethane;
- (c) an underlayer selected from the group consisting of cork, rubber and foam, adhered to a bottom surface of the waterproof core by a hot melt adhesive;
- (d) the waterproof core comprising an extruded dust and plastic composite, said waterproof core having substantially planar top and bottom surfaces separated by a thickness defining a first edge along a first side and a second edge along an opposite second side, and third and fourth edges along opposite third and fourth sides, wherein the first edge has a groove extending laterally into the waterproof core and the second opposite edge has a lateral protrusion from the waterproof core, the groove and protrusion having profiles shaped to form a click-lock edge fastening system.
(canceled)
The plank of claim 22 wherein the waterproof core further comprises less than 10% of additives selected from the group consisting of anti-oxidation agents, stabilizers, colorants, anti-fungus agents, coupling agents, reinforcing agents and lubricants.
The plank of claim 22 wherein the waterproof core further comprises calcium carbonate filler.
An engineered rectangular waterproof plank comprising:
- (a) a wear layer selected from the group consisting of cork, bamboo and wood veneer, said wear layer encapsulated in resin, and said wear layer adhered to a top surface of a waterproof core by a hot melt adhesive;
- (b) an underlayer selected from the group consisting of cork, rubber and foam, said underlayer adhered to a bottom surface of the waterproof core by a hot melt adhesive;
- (c) the waterproof core comprising:
- (i) at least about 55% of dust selected from the group consisting of wood, bamboo, cork and a combination of two or more of wood, bamboo and cork;
- (ii) at least about 20% of high-density polyethylene;
- and
- (iii) calcium carbonate filler;
- (d) said waterproof core having substantially planar top and bottom surfaces separated by a thickness defining an edge along opposite first and second sides, and along opposite third and fourth sides, wherein a groove extends laterally into the waterproof core along the first edge and a lateral protrusion extends from the opposite second edge of the waterproof core, the groove and protrusion comprising a click-lock edge fastening system.
