Problems solved by technology

[0002] During the welding process of the passenger car, there is a gap between the steel plate and the steel plate due to the error of the plate incoming material and the artificial welding method. In order to achieve the sealing effect, a self-adhesive asphalt damping sheet is usually used. During the welding process, the damping sheet Bonded to the middle of the gap. Under this welding process, there are strict requirements on the thickness of the damping film. If the damping film is too thick, it will increase the weight of the vehicle. If it is too thin, it will not achieve the effect of sealing and noise reduction. The damping film Asphalt is usually added for production, resulting in a strong odor of the damping sheet, which affects the use

Abstract

The invention discloses application of a low-odor asphalt damping pad to a passenger car. The low-odor asphalt is prepared from the following components in parts by weight: 4-7 parts of epoxy resin, 12-16 parts of asphalt, 13-17 parts of waste paint slag, 3-7 parts of rubber powder, 52-57 parts of filler, 1.5-2.5 parts of fiber and 2-4 parts of enhancer. The low-odor asphalt damping pad comprisesa low-odor asphalt damping pad body, the lower face of the low-odor asphalt damping pad body is coated with a layer of adhesive, and a ZC film is arranged on the lower face of the adhesive; micro-negative pressure pyrolysis equipment is adopted, natural inorganic filler (formed by processing natural clay inorganic matter) is added to serve as an additive, the equipment can achieve constant-temperature continuous discharging, the width and thickness of the damping plate can be adjusted at any time, the requirements of different vehicle types and specifications of the damping plate can be met, gaps between steel plates can be well filled, and the gaps can be filled more perfectly; besides, sound transmission is inhibited, and sealing and blocking of noise generated by air flowing are achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to the application of a low-odor asphalt damping pad on passenger cars. Background technique [0002] During the welding process of the passenger car, there is a gap between the steel plate and the steel plate due to the error of the plate incoming material and the artificial welding method. In order to achieve the sealing effect, a self-adhesive asphalt damping sheet is usually used. During the welding process, the damping sheet Bonded to the middle of the gap. Under this welding process, there are strict requirements on the thickness of the damping film. If the damping film is too thick, it will increase the weight of the vehicle. If it is too thin, it will not achieve the effect of sealing and noise reduction. The damping film Asphalt is usually added for production, resulting in a strong smell of the damping sheet, which affects the use. Contents of the invention [0003]...
