Problems solved by technology

[0003] With the increasing number of epidemic infectious diseases in recent years, there is a requirement for antibacterial properties on the surface of the product. Although the spatial network structure of the self-healing layer of the paint protection film gives it an excellent self-healing function, it also makes its surface exist. Easily penetrated by small molecules, and can absorb and accommodate microorganisms in the space grid

Abstract

The invention relates to the technical field of paint protection films, in particular to an antibacterial paint protection film. The paint protection film includes a transparent support, and a self-healing antibacterial protection film is sequentially arranged on an optical surface of the transparent support. layer and a transparent release film; an assembly glue and a translucent release film are sequentially arranged on the other optical surface of the transparent support. The self-healing antibacterial protective layer is formed by heating and curing after being coated with a self-healing antibacterial coating liquid. The self-healing antibacterial coating liquid protects the self-healing main resin, and the self-healing main resin has a hydroxyl value in the range of 120mgKOH / g~140mgKOH / g and two resins with hydroxyl value in the range of 50mgKOH / g~70mgKOH / g are mixed, and the mixing ratio is (7~9):(1~3). It can effectively fight against Escherichia coli and Staphylococcus aureus, and the self-healing layer has good penetration resistance.

Description

technical field [0001] The invention relates to the technical field of paint surface protection films, in particular to an antibacterial paint surface protection film. Background technique [0002] Paint protection film is a layer of transparent protective film attached to the paint on the surface of the product. It is mainly used in the automotive aftermarket, auto beauty and other industries to achieve the effect of protecting the original car paint of the car from external damage; it can also be used for Surface decoration of building materials, street lamps, guardrails and metal handles and other parts that need to be pasted with protective film. The product has strong toughness and self-healing function, which can effectively prevent scratches and gravel hits, and also isolate the contact between the paint surface and the air, and can prevent acid rain, asphalt, bird droppings, etc. from damaging the paint surface of the product. harm. At the same time, the paint prot...
