Abstract

The invention discloses a rubber jacket for a micro motor and a preparation method of the rubber jacket. The rubber jacket takes a TPE (thermal plastic elastomer) material as a base body, the TPE material comprises, in percentage by weight, 42-55% of a TPE, 12-25% of a hardening agent, 10-15% of softening oil, 0.05-0.2% of an antioxidant and 1-5% of CaCO3 which are mixed. The method comprises steps as follows: the TPE material is prepared from the TPE, the hardening agent, the softening oil, the antioxidant and CaCO3; the TPE material is taken as the base body for injection molding; cleaning and drying are performed; the qualified rubber jacket product is obtained after performance inspection. The rubber jacket and the preparation method have the benefits as follows: the rubber jacket can be prepared from the TPE material with an injection molding technology due to the plasticity of the TPE material, the rubber jacket is not required to be vulcanized after injection-molded, so that the cost is saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field related to micro motors, in particular to a rubber sleeve for a micro motor and a preparation method thereof. Background technique [0002] In the field of micro motors, rubber sleeves are mostly used as protective sleeves for motors, for protection, matching terminal assembly, and reducing motor noise, so rubber sleeves are widely used in micro motors. And the rubber cover in the existing product usually uses silica gel as a raw material. Silica gel alias: Silicone rubber is a highly active adsorption material, which is an amorphous substance, insoluble in water and any solvent, non-toxic, tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has m...
