Abstract

The invention discloses a multifunctional paint for protective film, which comprises the following raw material components in parts by weight: 40-60 parts of thermosetting acrylic modified polyurethane resin; 25-35 parts of self-cleaning polyurethane resin; 3-6 parts of isocyanate; 0.2-2.5 parts of hydrolysis stabilizer; 1-4 parts of UV absorber; 0.5-2 parts of hindered amine stabilizer; 8-12 parts of thinner; . The multi-functional coating used on the protective film provided by this solution has the functions of aging resistance, acid and alkali resistance, rain spot resistance, self-cleaning, high transparency, etc., and has good compatibility with various substrates such as PET, TPU, PVC, PI, etc. Adhesion, at the same time, has excellent self-healing ability, and can meet the multi-functional needs of outdoor protective films at the same time.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a multifunctional coating used on protective films. Background technique [0002] Many outdoor protective film products, such as paint protection film and external window film, etc., the substrates of these products are mostly PET, TPU, PVC, PI, etc. These substrates themselves do not have the function of anti-scratch Apply a layer of anti-scratch coating to protect the protective film from scratches such as sand and stones during installation and later use. [0003] With the continuous expansion of application fields, in order to meet various outdoor environments and usage needs, the anti-scratch layer is required to have functions such as aging resistance, acid and alkali resistance, rain spot resistance, self-cleaning, and high transparency. However, existing coatings used on protective films do not achieve this effect. Contents of the invention [0004] The present inven...
