Abstract

The invention discloses a regeneration production method of scrap rubber. The method is characterized by comprising the following steps: cleaning, pulverizing, removing impurities, screening, stirring, desulfurizing, extracting, refining, and discharging and forming. The discharging and forming process sequentially comprises the steps of primary plate pressing and secondary rolling forming. The plate pressing and rolling are matched to implement the formation of the regenerated rubber; by using the plate pressing, the rubber powder primarily forms a plate, thereby enhancing the overall density and uniformity; and the double-pass rolling is performed to effectively enhance the mechanical properties and swelling degree of the plate rubber.

Description

technical field [0001] The invention relates to a regeneration process of waste rubber, in particular to a regeneration production process of a waste rubber production sheet. Background technique [0002] my country is the world's largest producer of waste rubber. In 2009, my country produced 193 million waste tires with a weight of about 6.7 million tons. The corresponding output of recycled rubber is about 2.2 million tons, and the output of waste rubber powder is about 220,000 tons. At least 30% of waste rubber products are incinerated or landfilled as garbage, polluting the environment, occupying land, and wasting resources. [0003] Although my country's comprehensive utilization of waste tires has achieved certain results, it does not meet the current social and economic development requirements, and the resource and environmental problems it brings are becoming increasingly prominent. Therefore, it is very urgent to accelerate the comprehensive utilization of waste ...
