Abstract

The invention belongs to the field of polyurethane synthesis and concretely relates to a self-skinning compound material for a heat-resistant polyurethane foaming tyre and a preparation method thereof. The self-skinning compound material is prepared from a component A and a component B according to a mass ratio of 100: 80-90. The component A comprises polyether polyol, polymer polyol, a cross-linking agent and / or chain extender, a pore forming agent, a foam stabilizer, a catalyst and a foaming agent. The component B comprises polyester polyol and isocyanate. The self-skinning compound material can improve polyurethane heat resistance. The prepared tyre has excellent performances and can be used for a long time under conditions of loading and a high rate. The invention also provides a preparation method of the self-skinning compound material. The preparation method has reasonable processes.

Description

technical field [0001] The invention belongs to the field of polyurethane synthesis, and in particular relates to a self-skinning composite material for heat-resistant polyurethane foam tires and a preparation method thereof. Background technique [0002] Polyurethane microcellular elastomer has the advantages of high strength, good toughness, and light weight. Its excellent cushioning and shock absorption effect makes it gradually replace traditional rubber materials and is widely used in the preparation of vehicle soft parts, such as tires. [0003] Polyurethane microcellular elastomer foam tires have high bearing capacity and wear resistance. Different from traditional rubber tires, it has good cut and tear resistance, simple molding process, and low equipment investment; the tire does not need to be inflated, thus avoiding the concerns of air tire leakage and air leakage caused by sharp objects during use. , quite convenient to use. However, its internal molecular stru...
