UV hardening decorative film capable of being processed and formed deeply and preparation method of UV hardening decorative film

Abstract

The invention discloses a UV hardening decorative film capable of being processed and formed deeply and a preparation method of the UV hardening decorative film. A UV coating in the UV hardening decorative film consists of acrylic polyurethane, hydroxyl-containing resin and a photoinitiator. The UV coating can be used in the industries of printing products, aluminum material processing, transfer printing films and the like. The UV hardening decorative film is high in hardness and high in scratching resistance, has excellent mechanical property and chemical resistance, and can be processed and formed deeply, and a UV coated layer cannot be exploded. Hardening can be implemented without spraying equipment, production is flexible and convenient, a production process is environmentally friendly, and integral pollution emission can be reduced.

Description

technical field [0001] The invention relates to a decorative film and a preparation method thereof, in particular to a UV hardened decorative film which can be deeply processed and formed and a preparation method thereof. Background technique [0002] At present, the general decorative film uses UV hardening process, which is to print UV hardening paint directly on the surface of the film, and it can have high hardness after curing by UV light, but the user cannot perform deep forming treatment on the film when using it, such as deep drawing Processing, otherwise the UV coating is easy to burst, and the thickness of the applied UV coating should not be too thick, otherwise the coating is also easy to burst. However, if a product that requires deep forming treatment can only be used to compound the surface of the product with a decorative film, first deep draw the film, and then apply UV hardening liquid by spraying or showering, but spraying, spraying, etc. Compared with ro...

Problems solved by technology

[0002] At present, the general decorative film uses UV hardening process, which is to print UV hardening paint directly on the surface of the film, and it can have high hardness after curing by UV light, but the user cannot perform deep forming treatment on the film when using it, such as deep drawing Processing, otherwise the UV coating is easy to burst, and the thickness of the applied UV coating should not be too thick, otherwise the coating is also easy to burst

However, if a product that requires deep forming treatment can only be used to compound the surface of the product with a decorative film, first deep draw the film, and then apply UV hardening liquid by spraying or showering, but spraying, spraying, etc. Compared with roller coating, the liquid coating method has low efficiency, great environmental pollution and high labor intensity
