Polyurethane mixed component applied to slow-rebound damping pad and preparation method of polyurethane mixed component

The invention relates to a polyurethane mixed component applied to a slow-rebound damping pad and a preparation method of the polyurethane mixed component and belongs to the technical field of polyurethane application. The polyurethane mixed component applied to the slow-rebound damping pad is composed of a component A and a component B, and the weight ratio of the component A to the component B is 100 (50-60); the component A is composed of polyether polyol A, polypolyols, a cross-linking agent, a chain extender, a foam stabilizer, a catalyst and a foaming agent; the component B is composed of polyether polyol B and isocyanate. The pad made of the polyurethane mixed component is good in rebound effect, and the shock absorption capacity and the hand feeling are improved; the invention further provides a preparation method which is simple, easy to conduct and capable of saving energy and protecting the environment.
