Definitions
- the invention belongs to the field of optical films, and in particular relates to an epoxy-modified photochromic composition, a product and a preparation method, which are mainly applied to the production and processing of color-changing glasses and color-changing films.
- the other is the coating discoloration technology, which is a process in which the lens has been cured, and a layer of color-changing coating is applied on the surface, which is cured to form a film under certain conditions.
- This process perfectly solves the three defects of the substrate discoloration technology.
- due to the difficult development of this process the long R&D cycle and the harsh process requirements, this technology has been monopolized by foreign giants. After years of imitation by domestic eyewear manufacturers, the imitation of this technology has reached 80%.
- the coating color changing technology is a thermosetting technology. The coating color changing liquid is coated on the lens substrate and heated at a temperature of about 120 degrees for 2 hours to cure to form a film.
- the technology takes a long time, consumes high energy, and has low production efficiency, and the product qualification rate is only about 50%.
- Many domestic eyewear manufacturers have tried to develop coating color-changing photo-curing technology, but all ended in failure.
- the main reason is that photochromic powder has a certain lifespan. In the case of fading ability.
- the LED with a wavelength of 405 nm is radiated for 1 min and then thermally cured for 1 hour. Although the time of this process is shortened by half, it still has high energy consumption and low production efficiency, and cannot realize intelligent mechanized production.
- the object of the present invention is to firstly provide a photochromic composition based on epoxy modification.
- the photochromic composition can effectively solve the problem of damage to photochromic powder caused by ultraviolet light, and can also greatly shorten the discoloration of the coating. Glasses production time, and improve product yield, thereby reducing production costs.
- a photochromic composition based on epoxy modification the following components, in parts by weight, include:
- the catalyst is any one or more of 2.4.6-tris(dimethylaminomethyl)phenol, boron trifluoride ether, dimethylimidazole or triphenylphosphine; the polymerization inhibitor It is any one or more of hydroquinone, 2-tert-butyl hydroquinone, methyl hydroquinone and 4-methoxyphenol.
- a preparation method of the above-mentioned epoxy-modified photochromic composition is provided, and the dosage of each component is according to the above-mentioned weight portion, comprising the following steps:
- a preparation method of a product comprising the above-mentioned epoxy-modified photochromic composition, wherein the consumption of each component is according to the above-mentioned parts by weight, comprising the following steps:
- the base material is any one of polycarbonate material, polyurethane material or polyacrylic acid material.

- the principle of the present invention is: the present invention introduces the unsaturated carbon-carbon double bond of the olefinic anhydride and the flexible segment of the polyol into the epoxy system, and introduces the olefinic anhydride, which can not only provide a method for free radical curing, but also provide hardness after curing. and solvent resistance; the introduction of polyol flexible segments can improve the toughness after curing, and can also improve the discoloration speed and fading speed of the color-changing coating; at the same time, epoxy groups can provide a cationic curing method to form a dual curing system.
- the interpenetrating network structure is formed, which further improves the solvent resistance, reduces the shrinkage rate, improves the adhesion of the coating on the lens, and achieves the purpose of 100 grid 0.
- the high-energy electron beam bombards the carbon-carbon double bond in the polymer molecule to break it and generate free radicals. It is not necessary to add a free radical initiator, and the conversion rate of the double bond can be increased to more than 95%, the maximum The crosslinking density and solvent resistance are improved to a certain extent, so that the photochromic composition can be well adhered to the surface of the transparent substrate.
- the damage of ultraviolet light to the photochromic powder is avoided, the photochromic composition can be cured and formed into a film within a few seconds, the production efficiency and the qualified rate of finished products are improved, and the energy consumption and production cost are reduced.
- the preparation of the photochromic composition of the present invention and the implementation method thereof enable the photochromic coating composition to have good light transmittance, fastness, aging resistance and corrosion resistance on the substrate, and at the same time have good color depth and fading speed.

Description
本发明属于光学膜领域,具体涉及一种基于环氧改性的光致变色组合物、制品及制备方法,主要应用于变色眼镜及变色膜的生产与加工。
目前市面上的变色眼镜分为两种,一种是基材变色,是将光致变色粉溶解在树脂或单体里,然后浇筑在模具里,高温固化成型。该工艺存在以下几个缺陷:1、变色时出现变色深度深浅不一,容易出现熊猫眼的视觉,给客户带来极其不好的视觉体验。2、在制备半成品时,很多变色粉在半成品抛光研磨时被浪费掉,造成极大的成本负担。3、由于原材料限制,该工艺只能制备1.56和1.61镜片,无法制备1.67或1.71高附加值镜片。
另一种是涂层变色技术,是镜片已经固化好,在表面涂一层可以变色的涂层,在一定条件下固化成膜的工艺。该工艺完美的解决了基材变色技术的三个缺陷。但是由于该工艺的开发难度较大,研发周期较长,工艺要求苛刻,该技术一直被国外巨头垄断。国内眼镜生产企业通过多年模仿,该技术模仿程度已经达到80%,该涂层变色技术为热固技术,是将涂层变色液涂布在镜片基材上,在120度左右的温度下加热2小时固化成膜。该技术耗时长、能耗高、生产效率低,产品合格率仅为50%左右。国内多家眼镜生产企业尝试研发涂层变色光固技术,均以失败告终,主要原因是光致变色粉具有一定的寿命,在辐射光强较大的紫外光下,会出现发黄,甚至失去退变色能力的情况。现有技术中有提到采用波长为405nm的LED辐射1min后再热固1小时的工艺,该工艺虽然时间缩短一半,但是仍然能耗较高、生产效率低,无法实现智能机械化生产。
