Problems solved by technology

[0003] Although neoprene has the above-mentioned excellent properties, the cold resistance of neoprene is poor
In a low temperature environment, chloroprene rubber will produce a "self-sulfur" phenomenon, the Mooney viscosity will increase, and the raw rubber will harden, which greatly limits the application of chloroprene rubber.

Abstract

The invention discloses antifreezing rubber and a preparation method therefor. The antifreezing rubber comprises chloroprene rubber, graphene, paraffin, carbon black, mercaptoimidazoline, zinc oxide, sodium pyrophosphate, trioctyl trimellitate, alum powder and an additive, wherein the additive is prepared by soaking palm fiber of palm in a hydrochloric acid solution and filtering the palm fiber. The antifreezing rubber has excellent mechanical property and antifreezing property.

Description

technical field [0001] The invention relates to rubber, in particular to an antifreeze rubber and a preparation method thereof. Background technique [0002] Neoprene is a synthetic rubber produced by α-polymerization of chloroprene (ie 2-chloro-1,3-butadiene) as the main raw material. It is widely used in anti-weather products, viscose soles, coatings and rocket fuel. Neoprene has excellent physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance and chemical corrosion resistance. [0003] Although neoprene has the above-mentioned excellent properties, the cold resistance of neoprene is relatively poor. In a low-temperature environment, neoprene will produce a "self-sulfur" phenomenon, the Mooney viscosity will increase, and the raw rubber will harden, which greatly limits the application of neoprene. Contents of the invention [0004] The object of the present invention is to provide an antifreeze rub...
