The collagen/polymer matrix layer(s) are formed of a collagen blended with one or more polymers. The collagen blended within the polymer(s) can be dissolved within the polymer(s). The one or more collagen/polymer matrix layers can be attached to a substrate layer, for example a fabric layer.

Water-based adhesive composition are disclosed, the compositions comprising an acrylic dispersion, an epoxy-terminated polyester incorporated into the acrylic dispersion, and a water-dispersible isocyanate. Methods for laminating a first substrate to a second substrate are also disclosed, the methods comprising (a) providing an acrylic dispersion, (b) providing an epoxy-terminated polyester, (c) mixing the acrylic dispersion and the epoxy-terminated polyester, (d) mixing the mixture of (c) with a water-dispersible isocyanate to form an adhesive composition, (e) coating the adhesive composition of (d) on a surface of the first substrate, (f) drying the adhesive compositions on the first substrate to remove water, and (g) bringing the adhesive composition on the surface of the first substrate into contact with a surface of a second substrate, thereby laminating the first substrate to the second substrate. Laminates prepared comprising the water-based adhesives and according to the disclosed methods are also disclosed.

A waterborne polyurethane is provided. The waterborne polyurethane is formed by mixing a polyol, a diisocyanate, a dimethylol alkyl acid, and an epoxy resin into a mixture, and polymerizing the mixture. When the usage amount of the epoxy resin used is 1 part by weight, the usage amount of the polyol is 3 to 30 parts by weight, the usage amount of the diisocyanate is 1 to 10 parts by weight, and the usage amount of the dimethylol alkyl acid is 0.1-3.0 parts by weight. The epoxy resin includes an epoxy resin having a cyclic structure, a triacylglycerol having an epoxy group, or a combination thereof.

Disclosed a no-added formaldehyde composite wood product binder, a no-added formaldehyde composite wood product manufactured by same, and a preparation method for the composite wood product. The no-added formaldehyde composite wood product binder comprises an agent A and an agent B. The agent A is an isocyanate-based binder, and the agent B is an aqueous dispersion of polyester based aliphatic polyurethane and/or a modified polyester-based aliphatic polyurethane. The no-added formaldehyde composite wood product is formed under hot-pressing after a wooden and/or straw material is mixed with the no-added formaldehyde composite wood product binder. The composite wood product manufactured by the no-added formaldehyde composite wood product binder has excellent water-proof and mechanical properties and a good saw cutting performance, and the amount of isocyanate used is also reduced, thereby reducing costs.
