Abstract

The invention belongs to the technical field of rubber, and particularly relates to rubber for electric-generator shock pads and a preparation method of the rubber. The rubber is prepared from the following raw materials in parts by weight: 32-45 parts of acrylate rubber, 15-25 parts of polyurethane rubber, 10-16 parts of epichlorohydrin rubber, 10-18 parts of glass fibers, 5-10 parts of polytetrafluoroethylene fibers, 1-3 parts of carbon black N330, 3-6 parts of white carbon black VN, 0.5-1.5 parts of stearic acid, 2-6 parts of liquid paraffin, 10-15 parts of dibutyl phthalate, 1-2.2 parts ofantiagers DNP, 4-8 parts of dicumyl peroxide, 1-3 parts of N,N'-meta phenylene bismaleimide, 1-3 parts of silane coupling agents and 5-10 parts of accelerators CZ. The rubber has the advantages of appropriate hardness, high strength, small compression set deformation, high elasticity, high wear resistance, good shock absorption effect and suitability for preparation of the electric-generator shock pads.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a rubber for a generator shock absorber and a preparation method thereof. Background technique [0002] Generators often generate vibration during operation, which will generate noise and increase energy consumption. Therefore, shock absorbers are often used to eliminate vibration impact and absorb noise. The effect is poor, and the noise cancellation effect is not ideal. [0003] The publication number is CN105924703A. The Chinese patent application discloses a shock absorber for electric power generators and a preparation method thereof. The raw material components of the shock absorber are as follows, all in parts by weight: styrene-butadiene rubber 40-60 parts, neoprene rubber 20- 40 parts, 23-26 parts of fluoroether rubber, 0.1-15 parts of graphene, 13-15 parts of phenolic resin, 1-10 parts of silane coupling agent, 12-15 parts of semi-reinforced furnace black, 1...
