With the continuous improvement of people's awareness of environmental protection and energy conservation, under the premise of ensuring safety, automobile lightweight has become the trend of automobile development in the world. At present, there are two main ways of automobile lightweight:

1) using lightweight and high-strength materials, such as aluminum alloy, magnesium alloy, high-strength steel, etc.;

2) Improve automobile structure and reduce material consumption, such as thin-walled outer plate, cavitation in structural parts, etc.

However, reducing the amount of materials will also bring a series of problems:

1) if the steel plate becomes thinner, the local stiffness of the body will be reduced, and the impact energy absorption will be small in case of accidental collision, which will cause great safety risks to the personnel in the car;

2) the thin-walled outer plate will make the door, the top cover, the side wall and other large surface metal parts easy to produce large vibration during driving, which will radiate large noise.

Pcmape equipment has invented a kind of shock absorption reinforcing sheet improved with paint metal surface, which has a bonding layer made of epoxy resin and rubber, and the damping effect of the film is superior under the condition of the same thickness of 1-2.0mm. Pcmape automobile reinforcing pad, including aluminum foil support layer or glass fiber cloth support layer, butyl rubber adhesive layer and anti adhesive paper on the support layer; the thickness of strong adhesive layer is 1.2-2.0mm; The thickness of the support layer is about 0.2 ~ mm. The strength of pcmape damping reinforcement for automobile is high, which can improve the strength of automobile thin-walled sheet metal very well. At the same time, the bonding effect between pcmape and automobile thin-walled sheet metal is very good, and it is very convenient for workers to operate. Moreover, it is breathable, and the bonding layer will not have bubbles, warpage, and deformation of automobile thin-walled steel.

Before using the reinforcing film for the automobile, first cut it into the corresponding shape according to the specific shape of the parts to be strengthened for the automobile, then tear off the anti adhesion paper, open the supporting layer, adhesive layer and strong adhesive layer along one side, and then glue it to the parts to be strengthened, after baking at high temperature, make it reach the highest strength, so as to improve the strength of the automobile sheet .

Pcmape reinforcement can strengthen the strength of automobile sheet metal very well; at the same time, there is a strong adhesive layer on the adhesive layer made of butyl rubber, which greatly improves its adhesive ability; it can achieve the effect of increasing the strength of automobile sheet metal and reducing noise and damping.
