| description | The invention relates to a method for producing chlorosulfonated polyethylene rubber by using low-temperature freezing and crushing, belongs to the technical field of chemical engineering, and aims toproduce chlorosulfonated polyethylene rubber by crushing materials at low temperature. Materials are firstly cooled and enter a cavity of the mechanical pulverizer at a low temperature, the pulverizing effect is achieved under the combined action of high-speed rotation of the impeller, mutual repeated impact, collision, shearing, friction and the like between the materials and the blades, the gear ring and between the materials, and chlorosulfonated polyethylene rubber is prepared after pulverizing. Chlorinated polyethylene is ground into powder by using a low-temperature grinding technology,the particle size of the ground powder is reduced to 40-100 microns, the subsequent chlorosulfonation reaction speed is higher, and the grafting effect is better.
