Problems solved by technology

[0003] In order to protect the car and prevent ultraviolet rays from harming the human body, solar film is usually pasted on the glass of the car. In the prior art, high-temperature pyrolysis spraying method is used to manufacture anti-ultraviolet coated glass, but this coated glass reduces the transmittance of visible light , but also can not achieve the effect of full UV protection

Abstract

The invention discloses an anti-ultraviolet solar film, which includes the following components mixed by weight: 40-50 parts of PET polyester chips, 7-8 parts of an inorganic ultraviolet absorbent, 4-5 parts of an anti-scratch agent, 2-3 parts of an anti-adhesion agent, and 0.001-0.015 part of a beta-1# decomposition transparent agent. The invention discloses a preparation method of the anti-ultraviolet solar film. The anti-ultraviolet solar film provided by the invention adopts the beta-1# decomposition transparent agent, improves the intermiscibility of the absorbent and PET, thereby greatly increasing the usage amount of the inorganic ultraviolet absorbent, so that the anti-ultraviolet solar film can have an excellent anti-ultraviolet line effect and avoid the human body fatigue caused by ultraviolet rays, and can be used as electronic films, building films, automotive films, aircraft explosion-proof films and the like. The film is clear, and can completely isolate ultraviolet rays.

Description

technical field [0001] The invention relates to an ultraviolet-proof solar film and a preparation method thereof. Background technique [0002] Ultraviolet light is an invisible light with a shorter wavelength than visible light, with a wavelength range of 280nm-400nm, and has significant chemical effects. Ultraviolet rays not only come from sunlight, but various artificial light sources, such as ultraviolet lamps, computers, TVs, etc. will also produce certain ultraviolet rays. Excessive ultraviolet radiation can cause certain damage to human skin and eyes. Ultraviolet rays can damage human skin cells, cause wrinkles, spots, and premature aging of the skin. In severe cases, solar dermatitis and sunburn, or skin and mucous membrane damage Actinic keratosis, which causes cancer. Ultraviolet rays produced by ultraviolet rays can cause human fatigue, discoloration and embrittlement of furniture, especially for children, students and women. Long-term ultraviolet radiation will...
