Problems solved by technology

[0004] Natural rubber latex is widely used as a raw material for making master batches, but the latex composition of natural rubber is greatly affected by the place of origin, season, etc., and it is difficult to completely remove the moisture when using natural rubber latex, even after drying. Keep some water, in some environments, such as when synthesizing vulcanized rubber, the water vapor generated will increase the pressure in the mixer and affect production

Abstract

The invention discloses rubber. The rubber is prepared from the following constituents: chlorohydrin rubber, fluorinated silicone rubber, silicone rubber, polyurethane rubber, carbon black N100, paraffin, argil, sulfur, an antiscorching agent, nanometer zinc oxide, hydroxyl silicone oil, hydrogen silicone oil, zinc diethyl dithiocarbamate, 2-thiol imidazoline, a softener and a plasticizer. The rubber is good in cold-resistance performance, suitable for continuous and persistent application under a low temperature condition, meanwhile high in tensile strength, and good in fire resistance and corrosion resistance.

Description

[0001] technical field [0002] The invention relates to the field of rubber manufacturing, in particular to a kind of rubber. Background technique [0003] In the prior art, when molding a rubber composition containing a filler, in order to make it easy to process and improve the dispersibility of each component, a masterbatch is usually added. The masterbatch with dehumidification function is usually mixed with latex to prepare a mixed solution containing carbon black, silica and other fillers for coagulation, and then separate the coagulation and supernatant, dehydrate and dry the separated coagulation into masterbatch. [0004] Natural rubber latex is widely used as a raw material for making master batches, but the latex composition of natural rubber is greatly affected by the place of origin, season, etc., and it is difficult to completely remove the moisture when using natural rubber latex, even after drying. Keep some water. In some environments, such as when synthe...
