Embodiment 1

[0019] The method for utilizing waste rubber to process thermoplastic elastomer materials comprises the following steps:

[0020] ①Preparation of modified rubber powder: cut waste rubber into small pieces with a weight range of 400g, and ultrasonically clean them for 3 minutes; then pulverize them through a pulverizer, and pass through a 200-mesh sieve to obtain rubber powder; mix sulfur powder, silane coupling agent Si69, Polyethylene glycol and stearyl alcohol are mixed in a weight ratio of 5:2:50:10 and added to the waste rubber powder in the form of a spray. The amount added is 20% of the weight of the waste rubber powder. First, put it under an infrared lamp for 20 minutes. Then put the waste rubber powder into the ball mill and then add white carbon black for blending, then ball mill for 5 minutes at a speed of 1000r / min, then put the ball-milled waste rubber powder into the cold cathode fluorescent lamp irradiation box for 30 minutes, and pass nitrogen and gas into the b...

Embodiment 2

[0023] The method for utilizing waste rubber to process thermoplastic elastomer materials comprises the following steps:

[0024]①Preparation of modified rubber powder: cut waste rubber into small pieces with a weight range of 450g, and ultrasonically clean them for 5 minutes; then pulverize them through a pulverizer, and pass through a 200-mesh sieve to obtain rubber powder; mix sulfur powder, silane coupling agent Si69, Polyethylene glycol and stearyl alcohol are mixed in a weight ratio of 5:2:50:10 and added to the waste rubber powder in the form of a spray. The amount added is 25% of the weight of the waste rubber powder. Then put the waste rubber powder into the ball mill and then add white carbon black for blending and then ball mill for 10 minutes at a speed of 1000r / min, then put the ball-milled waste rubber powder into the cold cathode fluorescent lamp irradiation box for 50 minutes, and at the same time, nitrogen gas and Oxygen, so that the volume ratio of nitrogen a...

Embodiment 3

[0027] The method for utilizing waste rubber to process thermoplastic elastomer materials comprises the following steps:

[0028] ①Preparation of modified rubber powder: cut waste rubber into small pieces with a weight range of 425g, and ultrasonically clean them for 4 minutes; then pulverize them through a pulverizer, and pass through a 200-mesh sieve to obtain rubber powder; mix sulfur powder, silane coupling agent Si69, Polyethylene glycol and stearyl alcohol are mixed in a weight ratio of 5:2:50:10 and added to the waste rubber powder in the form of a spray. The amount added is 23% of the weight of the waste rubber powder. First, put it under an infrared lamp for 25 minutes. Then put the waste rubber powder into the ball mill and then add white carbon black for blending, then ball mill for 8 minutes at a speed of 1000r / min, then put the ball-milled waste rubber powder into the cold cathode fluorescent lamp irradiation box for 40 minutes, and pass nitrogen and gas into the b...

Abstract

The invention provides a method for processing thermoplastic elastomer by utilizing waste rubber and relates to the technical field of thermoplastic elastomers. By adopting the method for processing the thermoplastic elastomer by utilizing the waste rubber, on one hand, the waste rubber is recovered and then is processed into modified rubber powder, so that waste resources are very well optimized and configured, and the ecological environment is protected; on the other hand, the processed waste rubber powder is used as a main material, and natural plant fibers such as bagasse fiber and jute fiber and other rubber performance reinforcing agents are used as auxiliary materials, the prepared thermoplastic elastomer has the good properties of large hardness, large tensile strength, high elongation and high heat resistance, the safety of the thermoplastic elastomer material applied to electric wires and cables is ensured, and the service life of the electric wires and cables is prolonged.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a method for processing thermoplastic elastomer materials by using waste rubber. Background technique [0002] my country is a country that is very scarce in rubber resources. More than 40% of domestic synthetic rubber and more than 75% of natural rubber depend on imports. The utilization rate is only about 50%, which is less than 30% in western countries. There are still many places in our country where simple disposal methods such as landfill and incineration are adopted for waste rubber, or they are discarded at will, causing "black pollution". Waste rubber is a toxic and harmful solid waste, and its heat resistance and degradation resistance are very strong. It will not degrade after being buried in the ground for 100 years, which will cause serious environmental pollution and a great waste of resources. How to do a good job in the recycling and reuse of wast...
