Abstract

The invention belongs to the technical field of waste rubber recycling, and particularly to a 400 mesh fluorine rubber powder processing method. According to the present invention, the normal temperature mechanical processing method is used, and the waste fluorine rubber scraps are subjected to washing, impurity removing, crushing, magnetic separation metal removal, multiple crushing, auxiliary agent adding, and grinding to prepare the 400 mesh fluorine rubber powder; with the method of the present invention, the problem that the particle size of the rubber particles crushed by the common machine is large is solved, the performance of the obtained geometric material after the crushing is substantially superior to the performance of the rubber powder produced through the freezing method, the environmental pollution problem caused by direct discarding of the waste fluorine rubber scraps is solved, and the waste is turned into treasure; and the particle size of the product achieves 400 mesh, such that the application fields expand to the fields of rubber filling blending, plastic toughening modifying, paint and coating material toughening modifying, and the like, and the product with performances of wear resistance, no toxicity, no odor, acid resistance, alkali resistance and corrosion resistance can be produced.

Description

technical field [0001] The invention belongs to the technical field of recycling waste rubber, and in particular relates to a processing method for 400-mesh fluororubber powder. Background technique [0002] Fluorine rubber refers to a synthetic polymer elastomer that contains fluorine atoms on the carbon atoms of the main chain or side chain, referred to as FPM. Has excellent heat resistance, oil resistance, oxidation resistance and chemical resistance. The heat resistance of fluorine rubber is better than that of all other synthetic rubbers. It can work for a long time below 200°C and can withstand high temperatures above 300°C for a short period of time. Fluorine rubber can withstand immersion in various oils, fuels, concentrated acids, solvents, high-concentration hydrogen peroxide, etc., and its corrosion resistance is superior to other types of rubber. The tensile strength of fluorine rubber is relatively high, generally 10-30Mpa, and the elongation at break is 150%-...
