Abstract

The invention relates to a multifunctional environment-friendly polyurethane composite material and a preparation method thereof. The multifunctional environment-friendly polyurethane composite material comprises a thermoplastic polyurethane macromolecule, an environment-friendly additive which includes at least one substance selected from the group consisting of a recovered high polymer material, vegetable fiber, mineral and metal powder, and a tackifying dispersant which includes substances selected from the group consisting of natural rubber and synthetic rubber. In virtue of the tackifying dispersant, the environment-friendly additive can uniformly bond with the thermoplastic polyurethane macromolecule, so the composite material is formed. The environment-friendly additive enables environmental protection effect to be obtained; besides, cooperation between the environment-friendly additive and the tackifying dispersant enables the composite material to have the advantages of light weight, good slip limiting performance, excellent wear resistance, good formability and low cost.

Description

technical field [0001] The invention relates to a polyurethane polymer material and a preparation method thereof, in particular to a multifunctional environment-friendly polyurethane composite material and a preparation method thereof. Background technique [0002] In recent years, due to the awakening and rise of human beings' awareness of ecology and environmental protection, the use of environmentally friendly materials such as recyclable, lightweight, and easy-to-process has become an inevitable trend. Polymer composite materials can not only produce additive effects, but also retain the properties and characteristics of individual materials to form new materials with different properties. [0003] Thermoplastic Polyurethane (TPU) not only has the advantages of traditional engineering plastics, but also has excellent characteristics such as impact resistance, bending resistance, high elongation, high tear strength, and weather resistance. It is non-toxic and is widely u...
