Problems solved by technology

[0005] The existing vehicle damping materials mostly use asphalt damping pads. According to different vehicle models and different positions in the car, the required asphalt damping pads have many shapes and sizes and need to be laid manually, which increases the transportation and labor costs of materials; Sticky or magnetic asphalt damping pads, others cannot be used on vertical or inverted surfaces

Abstract

The invention discloses a water-based damping paint for an automobile. The water-based damping paint comprises the following components in percentage by weight: 20-40 percent of water-based acrylic emulsion, 0.3-0.8 percent of a surfactant, 0.1-0.5 percent of a bactericide, 0.1-0.5 percent of an anti-freezing agent, 0.3-0.8 percent of a dispersant, 50-70 percent of fillers, 0.2-0.5 percent of a thickening agent and 0.5-1 percent of water. The invention also provides a preparation method of the water-based damping paint for the automobile. The water-based damping paint for the automobile is used for solving the problems of transportation, construction and environmental protection characteristics of the prior art, has high solid content, wide temperature range and excellent shock absorption and noise reduction effects and also has the advantages of fire resistance, environmental protection, convenient construction and the like.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and relates to a water-based coating for vehicles with functions such as shock absorption, noise reduction and flame retardancy, in particular to a water-based damping coating for vehicles and a preparation method thereof. Background technique [0002] my country's automobile industry is in a period of rapid development. The improvement of vehicle comfort requirements and the enhancement of people's environmental awareness have prompted major automobile companies to formulate strict standards accordingly. The noise and vibration in the car directly affect the comfort of the ride. Therefore, the control of the noise in the car has become one of the important research directions in the automotive field. [0003] Damping vibration reduction and noise reduction technology is one of the methods to effectively control vibration and noise. It attaches high damping materials to the surface o...
