Abstract

The invention belongs to the technical field of damping materials, and particularly relates to a damping material and a preparation method and application thereof. The damping material is prepared from polyurethane rubber, maleic anhydride grafted polyolefin elastomer, modified polyurethane-epoxy acrylic resin, bisphenol S epoxy resin, polyimide, carbon black, titanium dioxide, glass fibers, stearic acid, a defoaming agent, an antioxidant, a vulcanizing agent and an accelerant; the preparation method of the damping material comprises the following steps: mixing the polyurethane rubber, the maleic anhydride grafted polyolefin elastomer, the modified polyurethane-epoxy acrylic resin, the bisphenol S epoxy resin, the polyimide, the carbon black, the titanium dioxide, the glass fibers, the stearic acid, the defoaming agent, the antioxidant, the vulcanizing agent and the accelerant, and carrying out vulcanization reaction to obtain the damping material. The damping material can solve the technical defects of poor wear resistance, poor aging, insufficient impact strength and poor flex fatigue resistance of a motor vibration damping pad in continuous use in the prior art.

Description

technical field [0001] The present application belongs to the technical field of vibration-damping materials, and in particular relates to a vibration-damping material and its preparation method and application. Background technique [0002] As a common equipment in mechanical equipment, motor vibration will bring many adverse effects in some occasions, such as increased loss, noise, etc. Due to the continuity of its operation and use, it is required to have good wear resistance and durability. Aging characteristics, during the operation of the motor, on the one hand, it produces noise and continuous vibration. Vibration-absorbing pads can reduce noise generation and minimize vibration, reducing the impact on the surrounding environment and personnel. Conventional motor vibration damping pads have problems such as poor wear resistance and aging, insufficient impact resistance strength, and poor flex fatigue resistance during use. [0003] Therefore, in order to reduce this...
