Abstract

The invention discloses a waterproof shielding protection film for spraying and a processing technology thereof, and particularly relates to the technical field of shielding protection films, and the waterproof shielding protection film comprises polyethylene resin, glucose, an antioxidant, an ultraviolet light absorber, a composite filler and an organic solvent. The high-temperature resistance of the waterproof shielding protection film for spraying can be effectively improved, the waterproof performance of the waterproof shielding protection film can be ensured, and the shielding protection film is prevented from being deformed and damaged; glucose is used as a reducing agent, so that silver nitrate can be quickly reduced into nano-silver particles, and the anti-static performance and the antibacterial performance of the shielding protection film can be effectively improved; by carrying out composite treatment on nano silicon dioxide aerogel and polyurethane, nano silicon dioxide aerogel / polyurethane composite fibers is prepared ; and nano silicon dioxide and polyacrylonitrile are compounded to prepare nano silicon dioxide / polyacrylonitrile composite fibers, so that the high-temperature resistance, the waterproof performance and the air permeability of the shielding protection film are further enhanced.

Description

technical field [0001] The invention relates to the technical field of masking protective film, more specifically, the invention relates to a waterproof masking protective film for spraying and its processing technology. Background technique [0002] Masking film, mainly used for covering paint, shielding paint and film materials for interior decoration during the painting process of automobiles, ships, trains, cabs, furniture and other products. The products are divided into high temperature resistant and normal temperature. The masking film is PE film As the base material, it is formed by compounding adhesive tape on it. The masking film can prevent paint leakage, which can effectively improve the traditional masking method of using newspaper plus textured paper. In the process of spraying automobile panels, the waterproof performance of the masking film is a very important criterion to prevent the paint from directly passing through the masking film and adhering to the s...
