Rubber composite material and preparation method thereof

Abstract

The invention discloses a rubber composite material and a preparation method thereof. The rubber composite material comprises 85 to 90 parts by weight of chloroprene rubber, 0.7 to 0.8 parts by weight of stearic acid, 10 to 11 parts by weight of zinc oxide, 3 to 3.5 parts by weight of polyethylene wax, 1 to 2.5 parts by weight of aromatic oil, 4 to 6 parts by weight of active magnesium oxide, 56 to 60 parts by weight of carbon black, 2 to 2.5 parts by weight of ethylene propylene diene monomer, 1.2 to 1.5 parts by weight of nylon short fibers with length of 2 to 3mm, 0.3 to 0.4 parts by weight of a vulcanizing agent, 6 to 7 parts by weight of an antiager, 2 to 3 parts by weight of a binder and 1 to 1.5 parts by weight of an accelerator. The nylon short fibers and the rubber composite material are mixed so that an embedded white silk-like pulling force is formed in the rubber composite material and thus the strength of the pulling force is improved and high temperature resistance, the wear resistance and fine crack resistance are obtained. The rubber composite material has strength far superior to that of the conventional rubber.

Description

technical field [0001] The invention relates to a technology for making rubber composite materials, in particular to a rubber composite material and a manufacturing method thereof. Background technique [0002] In the current prior art, a Chinese invention patent with the application number CN200710179841.3 is disclosed, which comprises the following steps: immersing expanded graphite with a layered crystal layer structure in water containing a surfactant or an organic solvent In the process, a suspension system of nano-graphite flakes is prepared by stirring and ultrasonic treatment, and then the suspension system is mixed with rubber latex or rubber solution, and then a flocculant is added for demulsification flocculation or poor solvent precipitation, and the flocs or sediments are dried into, After kneading and vulcanization, a graphite / rubber composite material is obtained. Introduce the emulsion (solution) blending process into the preparation of graphite / rubber nanoc...
