Abstract

The invention provides a type of damping coating for road vehicle, which is counted by weight and portions, and comprises the following raw materials: 145 to 155 portions of the waterproof emulsion, 45 to 55 portions of the anti-rust emulsion, 45 to 55 portions of the plasticized acrylic acid emulsion, 95 to 105 portions of the pure acrylic emulsion, 13 to 17 portions of film-forming booster, 8 to 12 portions of adhesive, and 585 to 615 portions of functional filler. The damping coating not only has excellent advantages of acid and alkali resistance, wide temperature field, etc., but also has good impact strength with degree 2 of ENISO 20567-1 stone chip resistance.

Description

technical field [0001] The invention belongs to the technical field of damping materials, and in particular relates to a damping coating for road vehicles, where the road vehicles specifically refer to special buses, such as blood donation vehicles and police buses. Background technique [0002] At present, in the floor, front wall, trunk, roof and door of the car, in order to endow the steel plate with damping performance, damping materials such as asphalt series or their composite series plates are used. On the floor and other parts, stamping is carried out according to the shape, and the formed vibration-damping material is placed on the automobile spraying line, and the asphalt series pressure-sensitive adhesive is used for positioning. When passing through the heating and drying oven, it can be bonded to the steel plate. However, asphalt is easily broken in winter, and the vibration-damping materials for façades such as the cowl are poor in environmental protection and ...
