Abstract
The present invention relates to a laminate, preferably a flooring laminate suitable for use wherever traction is needed or desired, whether due to natural or man-made conditions either indoors or outdoors. The laminate can be applied over existing flooring. The laminate includes a base layer and a traction layer including a grit material dispersed on a polymer. The base layer comprises a cured rubber blend which has been granulated to a predetermined size and subsequently rebonded with a polymeric base adhesive composition. At least some portion of the grit material of the traction layer protrudes from the polymeric composition to provide anti-slip properties.
Claims20
A slip-resistant laminate, comprising:
- a base layer comprising (a) particles of at least one cured recycled rubber and (b) a base adhesive composition, said base adhesive composition binding said cured rubber particles together;
- and
- a traction layer adhered to said base layer, said traction layer comprising a cured traction layer adhesive composition and a grit material, wherein at least a portion of said grit material is exposed on an upper surface of said traction layer to provide slip-resistant properties to said laminate wherein the base adhesive composition is present in an amount from about 2 to about 20 parts by weight per 100 parts of the rubber particles, wherein said rubber particles are about 6 mesh to about 18 mesh, wherein said base layer has a thickness from about 4 mm to about 12 mm, wherein said grit material is about 20 to about 40 mesh, wherein said traction layer adhesive composition is present in an amount from about 5 to about 20 parts by weight based on 100 parts by weight of the traction layer adhesive composition and grit material, and wherein said traction layer has a thickness of from about 0.75 mm to about 2 mm.
A slip-resistant laminate, comprising:
- a base layer comprising (a) particles of at least one cured recycled rubber and (b) a base adhesive composition, said base adhesive composition binding said cured rubber particles together;
- and
- a traction layer adhered to said base layer, said traction layer comprising a cured traction layer adhesive composition and a grit material, wherein at least a portion of said grit material is exposed on an upper surface of said traction layer to provide slip-resistant properties to said laminate, and wherein said base adhesive composition is an epoxy, hydrocarbon resin, acrylate, cement, polyurethane, or a combination thereof wherein said grit material comprises polymeric beads, polymeric particles, mineral particles, ceramics, or metal oxides, or a combination thereof, wherein said cured traction layer adhesive composition is polyurethane, wherein said rubber particles are a recycled styrene-butadiene rubber and natural rubber blend, wherein said styrene-butadiene rubber has a butadiene content of from about 30 to about 90 parts per 100 parts by weight of the styrene-butadiene rubber, wherein said rubber particles have a size from about 4 to about 20 mesh, and wherein said base adhesive composition is used in an amount from about 2 to about 20 parts by weight per 100 parts by weight of rubber.
A method for forming a slip-resistant laminate comprising the steps of:
- forming a base layer comprising particles of at least one cured rubber and a base adhesive composition, said base adhesive composition binding said cured rubber particles together;
- forming a traction layer on said base layer, wherein said traction layer comprises an uncured traction layer adhesive composition and a grit material, by applying the uncured traction layer adhesive composition on a surface of the base layer and applying the grit material on an upper surface of the uncured traction layer adhesive composition, wherein at least a portion of said grit material is exposed on the upper surface of said traction layer to provide slip-resistant properties to said laminate;
- and
- curing the traction layer adhesive.
