HIGH PERFORMANCE WATER-BASED ADHESION COMPOSITIONS AND APPLICATIONS

摘要

An adhesion composition comprising a) a first polymer that is selected from the group consisting of acrylic polymers, acrylonitrile butadiene, butyl rubber, cellulose acetate, cellulose butyrate, epoxy resins, ethylene vinyl acetate, natural rubber, neoprene, phenolic polymers, polyurethanes, polyvinyl acetate, polyvinyl alcohol, styrene butadiene rubber, casein, dextrin, starch, copolymers thereof and combinations thereof; b) a second polymer selected from the group consisting of ethylene-acrylic acid copolymer, oxidized polyethylene, oxidized ethylene-vinyl acetate copolymer, maleated polyolefin and combinations thereof; and c) a surfactant; where the composition is water-based, having a solids content of greater than about 30% based on the total weight of the composition, with a particle size of about 10 nm to about 2000 nm, and is adapted for adhesion to substrates; and where the first and second polymers are different. The adhesion composition can also comprise a tackifier resin selected from the group consisting of rosin ester resin, rosin acid resin, synthetic hydrocarbon resin, synthetic terpenic resin and combinations thereof. Applications of the composition are also disclosed.

1. An adhesion composition comprising:
(a) a first polymer selected from the group consisting of acrylic polymers, acrylonitrile butadiene, butyl rubber, cellulose acetate, cellulose butyrate, epoxy resins, ethylene-vinyl acetate copolymers, modified ethylene-vinylacetate, vinyl acetate copolymers, ethylene-(meth)acrylic acid ionomers, vinylidene chloride copolymers, ethylene-(meth)acrylate copolymers, polyesters, natural rubber, neoprene, phenolic polymers, polyurethanes, polyvinyl acetate, polyvinyl alcohol, styrene butadiene rubber, casein, dextrin, starch, polysaccharides, copolymers of two or more thereof and combinations of two or more thereof; and combinations of any two or more thereof; (b) a second polymer different than said first polymer and selected from the group consisting of ethylene-acrylic acid copolymers, oxidized polyethylenes, ethylene-vinyl acetate copolymers, oxidized ethylene-vinyl acetate copolymers, maleated polyolefins, homopolymers of polyethylene, homopolymers of polypropylene, and combinations of any two or more thereof; (c) surfactant; and (d) water, where the amount of said water, said first polymer and said second polymer is sufficient to provide the composition with a solids content of greater than about 30% based on the total weight of components (a)-(d) in the adhesion composition and where said first polymer and said second polymer comprise solid particles having a D50 particle size of from about 10 nanometers (nm) to about 2000 nm.
