Rubber-based composite material manufacturing method adopting functionally gradient grinding and polishing mode

Abstract

The invention discloses a rubber-based composite material manufacturing method by adopting a functionally gradient grinding and polishing mode. The method specifically comprises the following steps that different proportions of SiC abrasive particles are added into neoprene with the equivalent mass, and the 26 parts of mixed materials are fully mixed; the 26 parts of mixed materials are placed into a double roll mill with the temperature around 48-53 DEG C; the double roll mill is started for performing mixing, magnesium oxide, octadecanoic acid, naphthenic oil and zinc oxide are added in sequence, and 26 parts of rubber-based composite materials are obtained under the double roll rotary extrusion effect of the double roll mill; and each of the 26 parts of rubber-based composite materialsis taken out, placed into a dumbbell-shaped die and a circular die, clamped by two flat plates, and then placed into a full-automatic press vulcanizer with the temperature being 153+ / -2 DEG C for machining, and the formed composite materials are taken out of the dies and cooled to the room temperature. According to the rubber-based composite materials provided by the invention, the purpose for enhancing the elasticity modulus is achieved by adding the different proportions of SiC abrasive particles into the neoprene.

Description

technical field [0001] The present invention relates to the technical field of ultra-precision machining, and more specifically, relates to a method for manufacturing rubber-based composite materials using a gradient function grinding and polishing process. Background technique [0002] In recent years, composite materials have been widely used in the field of ultra-precision machining of hard and brittle materials. Luo Wei et al. used SnCl2.2H2O and Ce2(CO3)3.8H2O as raw materials, and ammonia water as a precipitating agent, prepared different proportions of tin-cerium composite oxides by wet solid-phase mechanochemical method, and the material removal rate of K9 glass reached 81.09%. nm / min. Armin et al. used the special non-rigid mechanical properties of PM-MA / SiO2 composite abrasive grains to regulate the contact friction between the abrasive grains and the processed surface, and obtained a flat processed surface by virtue of the synergistic effect of the organic core a...
