Abstract

The invention belongs to the technical field of polyurethane, and relates to a polyurethane composite material having a shape memory function sponge, and a preparation and using method thereof. The composite material comprises a component A, a component B and a component C, wherein the component A comprises polyether polyol and polymer polyol, a foam stabilizer and a foaming agent, and the component B comprises polyether polyol, isocyanate, a hardening agent and a polyether opening agent. The shape memory sponge can generate memory deformation along with temperature sensing and pressure, and has the advantages of moderate rebound speed, no obstructing and shrinkage, large physical mechanical strength, certain support strength and the like. By a mouse pad manufactured by the polyurethane composite material having the shape memory sponge, on one hand, the hardness and strength of the traditional memory sponge is improved, and the mouse pad has a certain support function for wrists; and on the other hand, the memory sponge has a temperature sensing effect and a shape memory function, so that the memory sponge can generate zero-pressure support for each part of the wrist, promote blood circulation for each part of the wrist, and relieve fatigue.
