Abstract

The invention discloses high-strength butadiene-styrene rubber and a preparation method thereof. The butadiene-styrene rubber is mainly prepared from the following components in parts by weight: 90-110 parts of butadiene-styrene rubber, 2-5 parts of methylacrylic acid, 0.4-0.8 part of an initiator and 2-5 parts of stearate. The butadiene-styrene rubber has excellent strength and low-temperature performance and is suitable for preparing high-quality weather-resistant wire and cable products.

Description

Technical field: [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high-strength styrene-butadiene rubber and a preparation method thereof. Background technique: [0002] Styrene-butadiene rubber (SBR) is a copolymer of styrene and butadiene. It is a synthetic rubber with good elasticity, wear resistance and crack resistance, and has good water resistance. It is a low-cost non-oil-resistant material. About 70% of SBR is used in the tire industry; it is also used in pipes, belts, shoes, etc. According to its performance, as long as it does not require heat resistance, oil resistance, and no special requirements, it can be used in all occasions. Therefore, it is a general-purpose glue, and the price is relatively cheap. However, its strength is poor and its low temperature performance is poor. Contents of the invention [0003] The object of the present invention is to provide a kind of high-strength styrene-butadiene...
