Abstract

The invention belongs to the technical field of waste and old rubber recovery and utilization, and specifically relates to a processing method of 200-mesh fluorine rubber powder. A normal-temperature machinery processing method is adopted, the leftovers of waste and old fluorine rubber are washed, impurities are removed, then the fluorine rubber leftovers are grinded, metals in the leftovers are removed through magnetic separation, the leftovers are grinded for several times, auxiliary agents are added, and finally the mixture is grinded so as to prepare the 200-mesh fluorine rubber powder. The particle size of rubber particles, which are prepared through grinding rubber by a normal machine, is too large, and the provided processing method solves the problem mentioned above. Moreover, the performance of the material processed by the provided processing method is greatly better than that of rubber powder, which is produced by a freezing method. The waste and old fluorine rubber leftovers can be recycled, the environmental pollution is reduced, and the wastes are converted into valuable resources. The particle size of the rubber powder reaches the 200-mesh level, thus the application range of the rubber powder is enlarged to fields of rubber filling and blending, plastic toughening modification, paint toughening modification, and the like, and the rubber powder can be used to produce products having advantages of wear resistance, no odor, no toxicity, alkali resistance, acid resistance, and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of recycling waste rubber, and in particular relates to a processing method for 200-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%-...
