A kind of production method and equipment of plastic environmental protection glue

Abstract

The invention discloses a production method and device for plastic environmentally friendly rubber. The method mainly comprises the following steps: sequentially performing high-speed shearing treatment, heating and plasticizing treatment, shearing and rubber refining treatment, granulation treatment and cooling treatment on waste tire rubber powder; and finally obtaining finished reclaimed rubberof the production method and device. According to the production method, physical desulfurization is achieved by firstly utilizing the methods of heating and shearing; granular reclaimed rubber is prepared; a green, energy-saving, continuous and efficient entire preparation process from the waste rubber powder to the environmentally friendly reclaimed rubber is achieved. The prepared reclaimed rubber has good physical properties, can be widely used in the fields of rubber chemical industry, tire manufacturing, transportation, construction, plastics, rubber products, and the like, can maintainproduct quality, enables product cost to be greatly reduced, and have broad market prospects.

Description

technical field [0001] The invention relates to a production method and equipment for plastic environmental protection rubber, in particular to a production method and equipment for plastic environmental protection rubber which realize physical desulfurization by heating and shearing, and belongs to the field of waste rubber utilization. Background technique [0002] Waste rubber comes from a wide range of sources, first of all waste tires. China is the third largest tire producer in the world, with an annual output of more than 500 million tires, second only to the United States and Japan. According to statistics, in 2014, the amount of waste tires produced in my country was about 293 million, reaching 10.8 million tons. About 1 billion tires are scrapped every year in the world, of which only 15-20% can be refurbished. The "black pollution" formed by more and more waste tires is threatening the living environment of all human beings. For this reason, many countries are ...

Problems solved by technology

The twin-screw extrusion method has high requirements on equipment materials and high operating costs. Once it is worn out, the output will decrease if the precision is small, and the product quality will also be difficult to control. It is rarely adopted in the market at present.

No matter which method is used to produce desulfurized rubber powder, it must be refined in a mill before it can become reclaimed rubber, and the secondary pollution to the environment is still very large.

[0006] From this point of view, the desulfurization process and refining and pressing process in the traditional recycled rubber production method will cause serious air and water pollution to the environment, and there are disadvantages such as high energy consumption, unsafety, and unstable product quality.
