Abstract

The invention relates to a microporous polyether urethane elastomer composite material and a preparation method thereof. The composite material is formed by the prepolymerization reaction of a polyhydric alcohol component A and a prepolymer component B, wherein the polyhydric alcohol component A comprises the following raw materials in the formula: 20 to 90 parts of polyoxytrimethyl-ene polyhydric alcohol, 5 to 50 parts of polyether polyol II, 5 to 50 parts of polymer polyether polyol, 2 to 30 parts of chain extender, 0.5 to 2 parts of nanometer graphene, 0.2 to 4 parts of foaming agent, 0.2 to 2 parts of foam homogenizing agent and 0.2 to 4 parts of catalyst; and the prepolymer component B comprises the following raw materials in the formula: 30 to 60 parts of diisocyanate, 4 to 20 parts of polyisocyanate modified by carbodiimide and 20 to 60 parts of polyoxytrimethyl-ene polyhydric alcohol. The polyether polyol II is formed by one or two of polyoxytrimethyl-ene epoxyethane copolyether polyol or / and polyethylene tetrahydrofuran polyol. The composite material provided by the invention is excellent in comprehensive mechanical property, antibacterial property and definite flame resistance.

Description

technical field

[0001] The invention belongs to the field of materials, and in particular relates to a polyether polyurethane microporous elastomer composite material and a preparation method thereof. Background technique

[0002] Polyurethane microcellular elastomer has the advantages of simple processing and molding, light weight, good elasticity, wear resistance, folding resistance, and good oil resistance because it combines the excellent properties of rubber and plastics. Its status is becoming more and more important, especially in shoe sole materials, load-bearing tires and automobile cushioning materials, etc., which have a wide range of applications. According to different raw materials, polyurethane microcellular elastomers used for shoe soles and solid core tires can be divided into two types: polyester type and polyether type. Polyester polyurethane microcellular elastomer has good physical and mechanical properties, but its hydrolysis resistance and low tempera...
