Problems solved by technology

However, the existing nitrile rubber also has fatal shortcomings, such as poor low temperature resistance, poor ozone resistance, poor insulation performance, and low elasticity, so its wearability is poor, and its scope of use is severely limited. When it belongs to cold environment, Nitrile rubber is prone to cracking and can easily cause serious hazards

Abstract

The invention discloses a hydrogenated epoxy vinyl resin-modified nitrile butadiene rubber material and a preparation method thereof. The hydrogenated epoxy vinyl resin-modified nitrile butadiene rubber material is prepared from the following raw materials in parts by weight: 40 to 70 parts of nitrile butadiene rubber; 10 to 25 parts of styrene butadiene rubber; 10 to 25 parts of epichlorohydrin rubber; 0.1 to 3 parts of vulcanizing agent; 4 to 12 parts of silicon powder; 4 to 10 parts of hydrogenated epoxy vinyl resin; 2 to 5 parts of anti-aging agent; 2 to 5 parts of plasticizer; and 15 to 45 parts of organic solvent. According to the hydrogenated epoxy vinyl resin-modified nitrile butadiene rubber material and the preparation method thereof provided by the invention, the preparation process is simple, not only are the oil resistance and leak tightness of the nitrile butadiene rubber ensured, but also the elasticity, tensile strength and low temperature resistance of the nitrile butadiene rubber are increased, and application to multiple aspects is met.

Description

technical field [0001] The invention relates to a hydrogenated epoxy vinyl resin modified nitrile rubber material and a preparation method thereof, belonging to the field of rubber modification. Background technique [0002] Nitrile rubber is produced by butadiene and acrylonitrile by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, strong adhesion, good water resistance, and air tightness. sex and excellent. Nitrile rubber is widely used in the production of various oil-resistant rubber products, various oil-resistant gaskets, gaskets, sleeves, flexible packaging, soft hoses, printing and dyeing rubber rollers, cable rubber materials, etc. Essential elastic material. However, the existing nitrile rubber also has fatal shortcomings, such as poor low temperature resistance, poor ozone resistance, poor insulation performance, and low elasticity, so its wearability is poor, and its scope of use is severely l...
