Problems solved by technology

[0004] The common disadvantage is that the increase in adhesion is less than the decrease in adhesion. Under the action of gravity, it is easy to drop the film, and the film falls in the interlayer. Not only does it have no reinforcing effect, but it is also difficult to take out.

Embodiment Construction

[0015] The production and use method of a vehicle body sheet metal reinforcing film of the present invention will be further described in detail below in conjunction with specific embodiments.

[0016] The invention relates to a production method of a body sheet metal reinforcing film. The body sheet metal reinforcing film is produced by adding epoxy resin at a mass percentage of 30%, and the body sheet metal reinforcing film is stamped using a laser die-cutting device.

[0017] A method for using a vehicle body sheet metal reinforcing film according to the invention, the vehicle body sheet metal reinforcing film is used after the electrophoretic primer of the vehicle body, and the vehicle body sheet metal reinforcing film is cured at 140° C. for 20 minutes.

[0018] The traditional ordinary sheet metal reinforcing film is directly pasted on the tinplate of the car body, and electrophoretic primer is required. The reinforcing film itself needs to be resistant to salt spray. Th...

Abstract

The invention provides a production method of a body sheet metal reinforcing film. The body sheet metal reinforcing film is added with epoxy resin at a mass percentage of 10% to 50% during production, and the body sheet metal reinforcing film is stamped Using laser die cutting device. The present invention also provides a method for using a body sheet metal reinforcement film, the body sheet metal reinforcement film is used after the body electrophoretic primer, and the body sheet metal reinforcement film is cured at 135-145°C for 15 ~25 minutes. Preferably, the vehicle body sheet metal reinforcement film is cured at 140° C. for 20 minutes during use. The present invention optimizes the proportion of epoxy resin in the base material and adjusts the dosage, thereby improving the adhesion of the sheet metal reinforcing film, being simple and convenient to operate, effectively ensuring customer needs, and reducing the operating cost of the enterprise.

Description

technical field [0001] The invention relates to the technical field of processing and application of polymer materials, in particular to a production and use method of a body sheet metal reinforcement film. Background technique [0002] The lightweight development of automobiles is the development direction of the automobile industry, and lightweight is conducive to energy saving and emission reduction. While reducing the weight, in order to ensure the safety of the car, the technology of reinforcing the film to improve the local strength is used in the key parts and weak parts of the car sheet. Automotive reinforcement film is mainly used for reinforcement of outer panels such as inner door panels, door handles, inner sides of hoods, roofs, wheel covers, side panels, etc., to improve the bending strength, stiffness, and impact resistance of steel plates, and improve the safety performance of vehicles , increase the anti-fatigue and damping effect of the steel plate, and im...
