Problems solved by technology

There are many types of materials for the raised part, most of which are relatively soft materials to reduce the pressure on the hands, but they must have a certain amount of support. For the time being, we have not found an ideal material that can do it at the same time.

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.

Description

technical field [0001] The invention belongs to the technical field of polyurethane, and relates to a polyurethane composite material with a shape memory function sponge and a preparation and use method thereof, in particular to a polyurethane composite material used for a mouse pad with a shape memory function and a preparation method and a use method thereof. Background technique [0002] As we all know, with the continuous advancement of science and technology, computers have increasingly become an essential tool for people to play games and entertain, obtain information, input and store information, and many people are directly engaged in computer-related work, and many people spend their time on computers. an average of more than six hours a day. The mouse is the main part of the computer control operation, according to its working principle and its internal structure, it can be divided into mechanical type, optical mechanical type and photoelectric type. Most computer...
