Abstract
A composite resin material exhibiting excellent physical properties, which is formed by adding semi-rigid or rigid polyurethane resin waste to a thermoplastic reactive resin, a nonreactive resin, a polymer alloy or the like. A first kind of the composite resin material is composed of a crosslinking polyurethane resin and a reactive resin, a nonreactive resin or a polymer alloy, which is formed by kneading the crosslinking polyurethane resin and the reactive resin, the nonreactive resin or the polymer alloy at a predetermined temperature or more. A second kind of the composite resin material is composed of a hydrolysis product of crosslinking polyurethane resin and a solid filler, which are mixed with a nonreactive resin and a polymer alloy by kneading. A third kind of the composite resin material is formed by kneading a moisture-absorbing crosslinking polyurethane resin, a reactive resin and one of a reactive resin, a nonreactive resin and a polymer alloy composed of a resilient rubber material and a thermoplastic resin at a temperature of not less than the hydrolysis temperature of the crosslinking polyurethane resin and not less than the melting point of the one of the nonreactive resin and the polymer alloy.
