A kind of double-layer steel plate reinforcing glue

Abstract

The invention discloses a double-layer steel plate reinforcing adhesive which consists of an upper-layer steel plate reinforcing adhesive and a lower-layer steel plate reinforcing adhesive. The double-layer steel plate reinforcing adhesive is particularly coated on fragile parts of a steel plate of an automobile body, and has the functions of insulating sound, damping and reinforcing the strength of the steel plate. According to the technical scheme of the invention, from the view of improving the adhesion property, the shrinkage of a cured product and the like, the effects of coating the steel plate, insulating the sound, damping and effectively improving the strength of the steel plate are achieved.

Description

technical field [0001] The technical field of automobile materials of the present invention specifically relates to a double-layer steel plate reinforcing glue, which is specially used to apply on vulnerable parts of automobile body steel plates (such as car doors, engine covers, etc.), to play the role of sound insulation and shock absorption, and enhance the strength of steel plates. Background technique [0002] Many automobile manufacturers increase the strength of the steel plate by sticking a layer of rubber strip material on the weak part of the steel plate. This method has defects such as the strip is easy to fall off, and the rubber strip is not suitable for the curved surface or curved parts of the steel plate. [0003] In addition, although some automobile factories spray a layer of steel plate reinforcement glue on the surface of the steel plate to achieve the effect of steel plate reinforcement and shock absorption, but in winter, the temperature is low, and afte...
