PROCESS FOR MANUFACTURING TPU ALLOY MATERIAL BY IN-SITU COMPATIBILIZATION

The present invention relates to a process for preparing a TPU alloy material through in-situ compatibilization. During the preparation, a dual-active substance is introduced, so that chemical bond connection between the TPU material and other materials such as polyolefin, TPE (Thermo Plastics Elastomer) or polyamide is achieved, and the compatibility among the materials is improved. The prepared alloy material has excellent mechanical property, wear-resisting property, chemical resistance, high/low temperature resistance, easy processing property and other performances of the TPU material; Meanwhile the binding ability of the alloy material and other materials is also improved, and the application range of TPU is expanded.
