Polyurethane composite material with embedded liquid healing network and preparation method therefor

Abstract

The present disclosure discloses a polyurethane composite material with an embedded liquid healing network and a preparation method therefor, belonging to the 5 technical field of polymer materials, and is composed of 40-60 parts of a polyurethane prepolymer, 5-20 parts of healing agent carrier particles, 10-30 parts of a liquid healing agent, and 0.1-1 parts of a dispersant. The composite material of the present disclosure solves the problem that polyurethane materials are easily damaged and have low repair efficiency during long-term use. The composite material of the present disclosure has fast, 10 efficient and self-adaptive repair performance in the case of large-scale damage and multiple times of damage, is suitable for complex environments such as acidic, alkaline, and high temperature environment, and has important application prospect in various fields of industrial equipment, flexible electronic equipment, automobile, and architecture, etc. 14 20 25 20 38 01 22 M ay 2 02 5 A B S T R A C T 2 0 2 5 2 0 3 8 0 1 2 2 2 0 2 5 M a y 1 0 1 4
