Problems solved by technology

[0003] Our country has developed and produced damping materials since the 1960s, among which the patent number is CN9110548407, and the name of the invention is "flame-retardant and damping coating layer constituting a constrained damping structure". Cracking under the stress cycle of time, so as to meet the vibration and noise reduction performance requirements of the material; ②It synthesizes the constrained layer and the damping layer, and the construction process is relatively complicated. The invention patent of the patent number CN85100715A is named "putty type damping material" Free damping material for shock absorption and noise reduction on the vibrating surface, but its damping wet area is wide, the composite loss factor is 0.05-0.08, and the damping performance is low

Abstract

The invention relates to a single-component, solvent-free, quake-proof and noise-control painting and a preparation method thereof. The painting comprises the following components in percentage by weight: 20-30 of modified epoxy resin with Tg being less than 20 DEG C, 0-10 of modified epoxy resin with Tg being between 20 DEG C and 80 DEG C, 10-20 of modified epoxy resin with Tg being more than 80DEG C, 20-30 of composite platy mica powder, 5-15 of rubber powder of 200 meshes, 2-10 of calcium carbonate of 400 meshes, 2-8 of graphite powder, 0.5-2 of antifoaming agent, 1-2 of anti-settling agent, 3-8 of lurking epoxy hardener; the components are evenly mixed and ground twice by a three-roller grinder and the finished product is obtained when no viscosity sagging is detected. Compared with the prior art, the invention is easy to be prepared, can form 3-5mm at one time without cracking with out solvent and is provided with higher loss factor; the compound loss factor is more than 0.1.Meanwhile, the painting can resist heat up to 150 DEG C, features in excellent anticorrosion property and more than 500h of salt fog resistance.

Description

technical field [0001] The invention relates to a solvent-free anti-shock and noise-proof coating, in particular to a one-component solvent-free anti-shock and noise-proof coating and a preparation method thereof. Background technique [0002] The engines or electromechanical equipment of many transport vehicles generate noise when they are running, and these noises can cause harm to the environment and people. Therefore, there is a need for a material that can eliminate these noise pollutions to resist the damage caused by these hazards to the human body. At the same time, because these devices are running at high speeds, their high-frequency vibrations are also inevitable, so these anti-noise materials must also be With anti-seismic effect. At the same time, these facilities operate in a high-temperature and high-humidity environment, so these anti-noise materials must have excellent anti-corrosion and high-temperature resistance effects. [0003] Our country has develop...
