Glue-free solar film manufacturing process

Abstract

The invention provides an adhesive-free solar film manufacturing process which comprises the following steps: 1, coating a coating roller with a transparent base material PET (Polyethylene Terephthalate) in a roller coating mode at 160-180 DEG C for coloring; 2, performing vacuum coating (plating metal onto the coated transparent base material at 600-700 DEG C in vacuum); 3, performing oxidation treatment (performing fixation oxidation treatment on the surface of a metal layer at 120-150 DEG C by using coating, so as to prevent oxidation dissociation; 4, forming and compounding the transparent base material with a polyvinyl chloride film to obtain a compounded material; 5, performing adhesive-free static treatment on the compounded material; 6, compounding and forming the material after the static treatment with the transparent PET film; and 7, performing later treatment, namely, cutting, forming and packaging a compounded finished product into a finished product, namely, the adhesive-free solar film. The adhesive-free solar film is resistant to ultraviolet rays, is free of adhesive and environmentally-friendly and easy to tear and adhere, has a metal effect, is capable of reducing the indoor temperature, can be adhered without adhesive, and is capable of reducing glass breakage impact force.

Description

technical field [0001] The invention relates to the technical field of thermal insulation films, in particular to a manufacturing process of an adhesive-free solar film. Background technique [0002] The existing solar insulation film is produced with glue, and the smell is very strong. The glue contains benzene and other harmful substances, which brings inconvenience to workers during production and is not conducive to the health of users or consumers. Under the sun's rays, the glass will generate high temperature and have a pungent smell. Once it is not used, it will be torn off and there will be glue spots on it, which is not easy to clean. It cannot be reused after being torn off. In modern solar film production technology, Aluminum, gold, copper, silver and other metals are often made into multi-layer high heat insulation metal film layers by vacuum spraying or magnetron sputtering technology. These products are often relatively thick and increase the cost. Contents o...
