Abstract

The invention discloses a water-based damping coating for automobiles, and the water-based damping coating is composed of the following components by weight: 40-60 parts of an aqueous emulsion, 12-20parts of plant fiber, 6-14 parts of graphite, 30-40 parts of calcium carbonate, 3 to 5 parts of a dispersing agent, 4 to 7 parts of a defoaming agent, and 18 to 26 parts of water. Compared with the prior art, the water-based damping coating has the following advantages: the plant fiber is added to increase the ductility and the crack resistance of the whole water-based damping coating and enhancethe connectivity among the components in the water-based damping coating, the damping coefficient of the water-based damping coating is enhanced, s the low temperature impact resistance of the water-based damping coating can be enhanced, and the added graphite greatly enhances pencil hardness on the surface of the water-based damping coating. The water-based damping coating has low volatile organic compounds and meets the requirements of environmental protection.

Description

technical field [0001] The invention relates to the field of automobile damping and shock absorption, in particular to a water-based damping coating for automobiles. Background technique [0002] Automotive damping and shock absorption, specifically, the suspension system vibrates due to the impact of the elastic element. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension. The shock absorber is mostly a hydraulic shock absorber. Its working principle is that when the frame (or body) and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity will repeatedly move. from one chamber to the other through different pores. [0003] The damping sheet is also called cement or damping block. It is a kind of viscoelastic material attached to the inner surface of the car body. It is close to the steel plate wall o...
