Sound-insulation and vibration-absorption damping slurry and production method

Abstract

The invention discloses sound-insulation and vibration-absorption damping slurry which comprises the following raw materials in parts by weight: 20-30 parts of water, 0.1-0.5 parts of cellulose, 0.1-0.2 parts of AMP-95 (2-amino-2-methyl-1-propanol), 0.5-2 parts of dispersing agent, 0.05-0.2 parts of wetting agent, 0.1-0.5 parts of defoaming agent, 5-10 parts of titanium dioxide, 10-20 parts of calcium carbonate, 10-20 parts of mica powder, 5-10 parts of vermiculite powder, 1-2 parts of film formation aid, 1-2 parts of glycol, 30-40 parts of styrene-acrylic emulsion, 0.05-0.2 parts of preserving agent, and 0.5-1 part of alkali swelling thickener. The sound-insulation and vibration-absorption damping slurry is lower in production cost, better in vibration-reduction effect and better in noise-reduction effect.

Description

technical field [0001] The invention relates to a damping slurry and a production method, in particular to a sound-insulating and vibration-absorbing damping slurry and a production method. Background technique [0002] In recent decades, with the development of modern industry, vibration tools and high-speed and automated mechanical equipment are increasing, and the problems of vibration, noise and fatigue fracture caused by them are becoming more and more prominent. In daily life, this kind of vibration and noise will endanger the health of the human body, and even lose the ability to work in severe cases; would have catastrophic consequences. [0003] Therefore, many damping slurry coatings are used to reduce vibration and noise on the surface of metal plate structures. The damping slurry coating is different from sound-absorbing materials. The principle is to convert vibration mechanical energy into heat energy and dissipate it. Conventional damping slurry coatings are...

Problems solved by technology

Conventional damping slurry coatings are made of acrylic IPN emulsion, damping pigments and fillers, flame retardants and additives. The cost of raw materials is high, which increases the production cost, and the performance of vibration and noise reduction is average.
