<p>The present invention relates to a film for protecting a coating layer of an automobile, to protect the coating layer of the automobile from external moisture or pollution while carrying or preserving the automobile, which prevents film and adhesive from being changed. The inner layer of the film for protecting the coating layer of the automobile is composed of polypropylene (PP) block copolymer with weight ratio of 90% and titanium oxide (TiO_2) with weight ratio of 10%; the middle layer is composed of polypropylene (PP) block copolymer with weight ratio of 60%, titanium oxide (TiO_2) with weight ratio of 10% and a UV blocker of weight ratio of 30%; and the outer layer is composed of polypropylene (PP) block copolymer with weight ratio of 90% and titanium oxide (TiO_2) with weight ratio of 10%, and a silicone adhesive is covered on the surface of the inner layer. The film for protecting the coating layer of an automobile according to the present invention constructs the inner layer, the middle layer and the outer layer using the polypropylene block copolymer as a main material to be thinned, thereby saving prime costs and being provided at a low price; has the effects of whitening the film, oxidizing harmful materials, expressing ultra-hydrophilic property and blocking ultraviolet rays by the UV blocker to protect the film; and maintains adhesiveness by polyorganosiloxane having 80-90 parts by weight of a silicone adhesive to present the silicone adhesive from being adhered to the coating layer at separation.</p> |
