Embodiment 1
[0029] Composition Amount (wt%)
[0030] Fluorescent whitening agent 0.800
[0031] UV absorber 0.500
[0032] β-1# decomposition enhancer 0.008
[0033] Base material balance
[0034] The sum of each component is 100wt%.
[0035] The above materials are made into an optical protective film, and the manufacturing process is as follows:
[0036] Mix the above-mentioned components evenly, melt and granulate, and then make a film with a thickness of 50 μm by calendering, extrusion blown film, extrusion salivation or solvent casting.
[0037] The film was tested for UV protection:
[0038] Place the RMB flat on a horizontal table with the front facing up, and irradiate the RMB with an ultraviolet lamp. The distance between the ultraviolet lamp and the banknote is about 5cm, and an obvious watermark will appear directly below the word "People". At this time, the above-mentioned film was placed between the RMB and the ultraviolet lamp, and the watermark disappeared completely ...

Abstract
The invention relates to a fully anti-ultraviolet, anti-fatigue, and anti-malignant melanoma optical protective material. The optical protective material is characterized by comprising the following materials in percentage by weight: 0.010 to 30.000 weight percent of additive and the balance of base stock, wherein the additive is a fluorescent whitening agent and / or an ultraviolet absorber, and also No.beta-1 decomposition antireflective agent, color-changing agent and / or toner can be added into the additive and the base stock. The optical protective material has the effect of full ultraviolet protection, namely 100 percent of ultraviolet UV400 protection, can prevent harmful light from causing human body to generate malignant melanoma, avoid human fatigue, furniture color change and embrittlement caused by the harmful light, particularly has better advanced protective effect on infants, students and young ladies, and can protect tender skin and slow down the aging process.
Description
technical field [0001] The invention relates to an improvement of an optical protective material, in particular to an optical protective material that is fully anti-ultraviolet, anti-fatigue and anti-malignant melanoma. 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. At the same time, ultraviolet radiation will also damage the Langerhans cells in the epiderm...
