At present, the traditional self-skinning products are all foamed by using a chlorofluorocarbon low-boiling point physical foaming agent, and after the products are proved to have strong damage to the atmospheric ozone layer, the products are classified as forbidden chemicals by various countries of the world.
Various countries have made a great deal of research on the substitution work of the physical foaming agent, and the traditional formula is adjusted from the perspective of the original preparation system. For example, in the patent with publication number "CN201711295694.6", entitled "a polyurethane self-skinning foam and method for preparing same", water is used as a foaming agent, but this causes lack of rigid chain links in the polymer system, so that the mechanical properties such as compression load, hardness, tensile strength and the like of the product are reduced, specifically: the water is used as the foaming agent, so that the viscosity of the combined material is increased, the fluidity of the material is deviated, the rigid structure of the foam body is increased in a foaming system, and the mechanical property of the product is reduced, thereby reducing the thickness of the self-skinning surface.
Steering wheel in car, instrument desk are mostly from skinning type, because in car inside needs to keep environmental protection requirement, and have no smell.
Based on the reasons, the invention designs a formula of the self-skinning product for the automobile, wherein polyether polyol, aromatic diamine and low-molecular-weight diol are used as chain extenders for polymer synthesis in the formula, so that the mechanical property of the foam is improved, the speed of polymer chain growth reaction is accelerated, and the hardness and modulus of the foam are increased.
