Problems solved by technology

The average pH value of seawater is 8.2, which is highly corrosive. 3.5% of seawater is salt. These salts are mainly composed of chlorine, sodium, sulfur, magnesium, calcium, potassium, bromine, etc. SBR products are exposed to seawater for a long time. environment, it is inevitable that the performance will deteriorate with the aging time, which will have an adverse effect on the normal use and storage of the product

Abstract

The invention provides a preparation method of a styrene-butadiene rubber composite material. The preparation method comprises the following steps: (1) dissolving petroleum resin in a non-polar solvent to obtain a petroleum resin solution; dissolving butadiene styrene rubber in a non-polar solvent under a heating condition to obtain a butadiene styrene rubber solution; dispersing the fibrous filler into a non-polar solvent, adding the petroleum resin solution under a stirring condition, stirring for 2-5 hours, then adding the butadiene styrene rubber solution, and stirring for 2-5 hours to obtain a mixed solution; (2) heating the mixed solution in an oil bath until the temperature is over the boiling point of the non-polar solvent to evaporate the non-polar solvent, then putting the mixed solution into an oven, and drying at the temperature of 60-90 DEG C to obtain a mixture; and (3) mixing the mixture, an anti-aging agent, zinc oxide and stearic acid, adding an accelerant and a vulcanizing agent, and carrying out mixing vulcanization to obtain the styrene-butadiene rubber composite material The styrene-butadiene rubber composite material prepared by the method has excellent corrosion resistance and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a highly elastic and corrosion-resistant styrene-butadiene rubber composite material and a preparation method thereof. Background technique [0002] Styrene-butadiene rubber (SBR) is a copolymer of butadiene and styrene. It is the earliest industrialized synthetic rubber, and it is a general-purpose synthetic rubber variety with the highest output and largest consumption in the world. The physical and mechanical properties, processing properties and product performance of styrene-butadiene rubber are close to those of natural rubber, and its wear resistance, heat resistance and aging resistance are better than those of natural rubber. It is one of the best substitutes for natural rubber. [0003] The research on styrene-butadiene rubber in my country began in the 1950s. In recent years, the variety and grade of styrene-butadiene rubber products in my country have continue...
