Problems solved by technology

At present, the anti-ultraviolet film on the market is mainly used to block ultraviolet rays, block some heat, etc., but the anti-ultraviolet film in the prior art has problems such as short service life, easy to be damaged by sharp objects, easy to fall off, not waterproof, etc., which is harmful to the environment. Poor adaptability, foreign matter is easy to attach and difficult to clean, corrosion resistance, and stability are not ideal, and some materials are unreasonably selected, and the anti-ultraviolet film prepared by it has defects such as relatively simple anti-ultraviolet function

Abstract

A composite protective film is composed of a release layer, an adhesive layer, a weather-proof protective layer and a hydrophobic layer which are compounded into a whole, wherein the release layer isa bottom layer, the surface of the release layer is attached to the bottom surface of the adhesive layer, the bottom surface of the weather-proof protective layer is attached to the surface of the adhesive layer, and the hydrophobic layer is a surface layer and attached to the surface of the weather-proof protective layer. According to the invention, the structure is improved, the hydrophobic layer is attached to the surface of the weather-proof protective layer; adhesion of foreign matters such as outdoor dirt, dust, rain and snow on the surface of an object or equipment is reduced by utilizing the hydrophobic property of the hydrophobic layer; therefore, the external environment resistance of the object or equipment surface is improved; meanwhile, the weather-proof protective layer is used in cooperation, good ultraviolet resistance is achieved, the problems that the composite protective film is prone to aging, corrosion and the like due to ultraviolet rays can be solved, the composite protective film can be prevented from being damaged by sharp objects, and the service life of the composite protective film is prolonged.

Description

technical field [0001] The invention relates to a composite protective film. Background technique [0002] Ultraviolet radiation is a form of radiation that has a great influence on the stability of the exterior surfaces of outdoor buildings. At present, the anti-ultraviolet film on the market is mainly used to block ultraviolet rays, block some heat, etc., but the anti-ultraviolet film in the prior art has problems such as short service life, easy to be damaged by sharp objects, easy to fall off, not waterproof, etc., which is harmful to the environment. Poor adaptability, foreign matter is easy to attach and difficult to clean, corrosion resistance, and stability are not ideal, and some materials are unreasonably selected, and the anti-ultraviolet film prepared by it has defects such as relatively simple anti-ultraviolet function. Therefore, further improvement is necessary. Contents of the invention [0003] The object of the present invention is to provide a composit...
