NOVELTY - Automobile paint surface protective film comprises 30-50 pts. wt. polyamide resin, 10-20 pts. wt. transparent soft rubber, 4-8 pts. wt. bisphenol F type epoxy resin, 3-6 pts. wt. calcium carbonate, 2-3 pts. wt. aluminum oxide, 2-6 pts. wt. graphene absorbent, 1-3 pts. wt. polytetrahydrofuran glycol, 2-6 pts. wt. light stabilizer, 2-4 pts. wt. optical level acrylic ester and 1-3 pts. wt. adhesive. USE - The automobile paint surface protective film is useful: for protecting the original factory vehicle paint of the automobile from damage; and for preventing the scratch and sand impact, and isolates the vehicle paint and air contact can prevent acid rain, asphalt, and bird and so on the damage to the paint surface. ADVANTAGE - The paint surface protective film has anti-scraping, wear-resisting, ultraviolet resistance, alkali resistance and rain spot resistance, good integral toughness, good impact resistance and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing automobile paint surface protective film comprising (a) mixing polyamide resin, transparent soft rubber, bisphenol F type epoxy resin, adding into stirrer, and stirring to obtain mixture A, (b) adding calcium carbonate, aluminum oxide, graphene absorbent, polytetrahydrofuran glycol, light stabilizer, fully mixing, continuously stirring at normal temperature to obtain the mixture B, (c) adding optical level adhesive acrylic ester to the mixture B, stirring at 50-60℃ in stirring barrel to obtain mixture C, (d) sending the mixture C material into the film-forming stretching device, stretching and molding to obtain the primary paint surface protective film, and (e) finally using trimming machine and winder, cutting and rolling according to the requirement, and storing in storage.
