Embodiment 5

[0036] In embodiment 5, step 3 is omitted, and other steps remain unchanged.

[0037] Since a large amount of reclaimed rubber powder is used in the formula, the fluidity is relatively low, so the twin-screw should strengthen the mixing effect in the arrangement of the screw structure, so that the rubber powder can be evenly distributed in the matrix resin SBS, so that it has good processing performance .

Abstract

The invention relates to reclaimed rubber material and a manufacturing technique thereof and discloses the reclaimed rubber material. The raw material formula of the reclaimed rubber material comprises the following components in part by weight: 12 parts of matrix resin SBS, 12 parts of naphthenic oil, 1.5 parts of flow promotor, 10 parts of mineral filler, 49 parts of rubber powder, 15 parts of EVA and 0.5 parts of anti-aging promotor. The reclaimed rubber material provided by the invention not only makes full use of the characteristics of high elasticity, aging resistance, temperature and cold resistance of reclaimed rubber but also makes use of the characteristics of thermoplastic processing, environmental friendliness, energy conservation and high productivity of the matrix resin SBS. Therefore, the reclaimed rubber material conforms to the strategy of sustainable development better.

Description

technical field [0001] The invention relates to a new polymer material, in particular to a regenerated rubber material, and also relates to a manufacturing process of the material. Background technique [0002] my country has always been a big country in the use of rubber, but 70% of my country's rubber resources depend on imports, and it is a country with serious shortage of rubber resources. The recycling of waste rubber powder has effectively improved the utilization rate of rubber resources and eased the shortage of rubber materials in my country. Especially since the Fourth Plenary Session of the 16th CPC Central Committee put forward "vigorously develop circular economy and build a conservation-oriented society", China's waste rubber powder recycling industry has developed by leaps and bounds, and has successfully laid the foundation for the recycling of waste rubber powder. status of a great power. In 2006, China's rubber powder output reached 300,000 tons, an incre...
