Abstract

The invention relates to a preparation method of a waste rubber powder / polyene resin thermoplastic elastomer. The preparation method is characterized by comprising the following steps of: firstly pouring 5-50 weight parts of a waste rubber powder, 2-10 weight parts of an interfacial modifier, 0-3 weight parts of an initiator and 1-2 weight parts of processing oil into a high-speed mixer and mixing for 5-10 min; pouring 100 weight parts of a polyene resin into the high-speed mixer and mixing for 2-5 min; pouring the mixture into an internal mixer or double screw extruder for mixing, mixing at 130-200 DEG C for 2-10 min; and granulating to obtain the waste rubber powder / polyene resin thermoplastic elastomer. The thermoplastic elastomer prepared in the invention can be repeatedly used for plastic processing. The production technology is simple, requires low cost and produces little pollution.

Description

technical field [0001] The invention relates to the preparation of a thermoplastic elastomer that can be repeatedly plasticized and processed, in particular to a preparation method of waste rubber powder / polyolefin resin thermoplastic elastomer. The utility model belongs to the technical field of recycling waste materials. Background technique [0002] Due to the current high prosperity of the global polymer material industry, the recycling and utilization of waste polymer materials has become very urgent. my country is a big rubber consumer, and since 2002 it has surpassed the United States to become the world's largest rubber consumer. During the use of rubber, a large amount of waste rubber has appeared due to its easy aging and difficulty in natural degradation, forming a relatively serious "black pollution". Waste rubber is a thermal solid polymer material, which is difficult to degrade after being discarded. It will not rot and deteriorate in nature for more than ten...
