Damping rubber

Abstract

The invention discloses damping shock absorption rubber which is prepared from the following components in parts by mass: 35-40 parts of rubber nanospheres, 40-65 parts of water-soluble acrylic resin, 5-10 parts of light calcium carbonate, 10-11 parts of water, 2.0-2.6 parts of a foaming agent, 2-3.5 parts of carbon black, 0.2-0.5 part of a tackifier, 5-8 parts of dioctyl terephthalate and/or diisononyl phthalate, 2-8 parts of carbon nanotubes, 1-3 parts of an adhesion promoter, 1-4 parts of a stabilizer and 3-5 parts of a flexibilizer. By adding a certain proportion of rubber nanospheres, the elastic effect of the rubber nanospheres is effectively utilized, and after the rubber nanospheres are adhered to the surface of an automobile through water-soluble acrylic resin, a very good damping effect is achieved; and by adding the light calcium carbonate and the carbon nanotubes, the weight of the coating is greatly reduced while the strength of the coating is ensured, and the light weight of the coating is realized.

Description

technical field [0001] The invention relates to a damping glue, in particular to a damping damping glue. Background technique [0002] Vibration is ubiquitous in real life, and the phenomenon of vibration cannot be ignored and indispensable. People have been devoted to the research on the generation, control and elimination of vibration. However, vibration will also have many adverse effects on people's lives. For example, resonance will cause damage to mechanical equipment, and noise generated by cars, high-speed trains, etc. will affect the living environment of human beings. How to reduce the adverse effects of vibration on people? Minimizing is the current development and pursuit of shock absorption technology. [0003] The requirements for low cost, high quality and noise reduction of vehicles are increasing every year. In order to meet the market demand, noise reduction materials have developed rapidly. The representative asphalt damping plate among noise reduction ag...
