Abstract

The invention discloses fiber reinforced rubber. The fiber reinforced rubber is prepared from raw materials by weight as follows: chloroprene rubber, nitrile rubber, butadiene rubber, formaldehyde co-condensed resin, viscose fibers, polyamide fibers, carbon black, zinc oxide, stearic acid, a vulcanizing agent, an accelerant, an anti-aging agent and a reinforcing agent. The invention further provides a preparation method of the fiber reinforced rubber. Due to addition of the viscose fibers and the polyamide fibers, the service life of the fiber reinforced rubber can be effectively prolonged, the material is seldom deformed and has high bearing capacity and high grease resistance and acid-alkaline corrosion resistance, the hardness and the tensile strength of the fiber reinforced rubber can be improved remarkably, and the fiber reinforced rubber is suitable for production in various fields.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a fiber-reinforced rubber and a preparation method thereof. Background technique [0002] Rubber is an elastic polymer. Rubber is divided into natural rubber and synthetic rubber according to raw materials. According to the shape, it can be divided into block raw rubber, latex, liquid rubber and powder rubber. Latex is a colloidal water dispersion of rubber; liquid rubber is an oligomer of rubber, which is generally a viscous liquid before vulcanization; powder rubber is processed from latex into powder to facilitate batching and processing. The thermoplastic rubber developed in the 1960s does not require chemical vulcanization, but is formed by the processing method of thermoplastics. Rubber is divided into two types: general-purpose and special-purpose according to the use. It is an insulator and does not conduct electricity easily, but if it is exposed to water or...
