Abstract

The invention belongs to the technical field of composite materials, and particularly relates to a self-repairing high-elastic polyurethane / POE composite material, which comprises, by weight, 45-72 parts of thermoplastic polyurethane, 5-10 parts of POE resin, 14-18 parts of a filler, 0.5-2 parts of an interfacial compatibilizer, and 8.5-25 parts of a functional auxiliary agent, the sum of the parts by weight of the components is 100, the thermoplastic polyurethane comprises a modifier, and the POE resin comprises a silane coupling agent. The modifier accounts for 5-25% of the thermoplastic polyurethane by weight, and the modifier is one or more of tetrafluoroethylene, carbon fiber or a porous nano material; the invention also provides a preparation method of the self-repairing high-elastic polyurethane / POE composite material. The advantages of thermoplastic polyurethane and POE resin are fully exerted, the self-repairing performance and high elasticity of the composite material are remarkably improved, the preparation process is simple, energy is not consumed, complex reactions are not involved, volatile by-products are not generated, and energy and cost are saved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a self-healing high-elasticity polyurethane / POE composite material and a preparation method thereof. Background technique [0002] When high-elastic materials are impacted, they can play a certain buffering role to prevent damage to objects, and play a positive role in extending the service life of objects. Therefore, high-elastic materials are widely used in daily life. With the continuous advancement of economy and technology, the application of high-elastic materials is becoming more and more extensive, and people have put forward higher requirements for the performance of high-elastic materials. [0003] Therefore, the research and optimization of high elastic materials is still a hot spot today. As an excellent elastomer, polyurethane has properties between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high ha...
