Abstract

The invention relates to an all-solid-content UV (ultraviolet) bright scratch-resistant coating for BOPP (biaxially-oriented polypropylene) precoating, basically comprising nano composite polyurethane acrylate oligomer, aliphatic polyurethane acrylate oligomer, monomer I, monomer II, photoinitiator I, photoinitiator II, a defoaming agent, a wetting agent, and a leveling agent. The invention also relates to a preparation method of the all-solid-content UV scratch-resistant coating. The scratch-resistant coating prepared herein is applied to the surface of BOPP precoating film through a flexible plate, the surface hardness of the BOPP precoating film is significantly improved at the premise of ensuring gloss and friction coefficient of the BOPP precoating film itself, and scratch resistance of the BOPP precoating film is improved; in addition, the subsequent processes for the surface of the BOPP precoating film, such as UV process and gilding process, are significantly improved.

Description

Technical field [0001] The invention relates to the field of paint preparation, in particular to a full-solid UV bright anti-scratch paint for BOPP pre-coating film and a preparation method thereof. Background technique [0002] BOPP pre-coated film is a very important flexible packaging material. It has colorless, odorless, non-toxic, high tensile strength, toughness and good transparency. After coating, it can be coated on the packaging material to play a good waterproof , Anti-tearing and other protective functions, especially the bright BOPP pre-coated film, which can give people a high-gloss luxury feeling when covering the packaging material, which is very popular with consumers. However, packaging materials coated with bright BOPP pre-coated film often come in contact with hard objects during transportation and normal use, and scratches or scratches will occur under the action of external impact, which will affect the appearance of the packaging materials. [0003] The so-c...
