Abstract

The invention relates to a rubber intensifier which contains the following raw material components in parts by weight: 20-30 parts of cashew nut oil and 12-18 parts of hexamethylenetetramine. The method for preparing the cashew nut oil comprises the following steps: uniformly mixing cashew kernel with absolute ethyl alcohol, and then heating; grinding cashew nut shells so as to obtain cashew powder, and drying the cashew powder; uniformly mixing the two products, pressing at a low temperature, filtering the crude oil obtained by low-temperature pressing, and collecting the filtrate, thereby obtaining the cashew nut oil. According to the rubber intensifier as well as the preparation method and application thereof, provided by the invention, the effect of the rubber intensifier for intensifying the rubber can be improved, the heat resistance, aging resistance, wear resistance, scratch resistance and corrosion resistance of the rubber are improved, the rubber aging process is effectively retarded or inhibited, the strength and the rubber flexibility are perfectly combined, and the physical and mechanical properties of the rubber are improved; and moreover, the preparation method is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber reinforcing agent and its preparation method and application. Background technique [0002] Rubber is an elastic polymer that can be obtained from the sap of some plants or synthetically. Rubber is divided into natural rubber and synthetic rubber according to raw materials, and synthetic rubber is divided into general synthetic rubber and special synthetic rubber. Among them, general-purpose synthetic rubber refers to rubber types that partially or completely replace natural rubber, such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, etc., which are mainly used for the manufacture of tires and general industrial rubber products. The demand for general-purpose rubber is large, and it is the main variety of synthetic rubber. In the process of artificially synthesizing rubber, it is usually necessary to add a rubber reinforcing agent to improve t...
