Problems solved by technology

[0003] Although these composite materials have the above-mentioned respective characteristics, there are certain application limitations in use, that is, for example, in the textile field, the fabric is too thin, and its light-shielding performance is not good. If the fabric is too thick, because of its good light-shielding performance, On the contrary, it affects the light, especially absorbing too much light, which will cause the fabric to heat up and affect the use. If it is applied to the field of curtains, it is especially impossible to judge the time of day through the curtains. Moreover, the shading performance is determined by the thickness and color of the curtain fabric. To achieve this, the use of such fabrics affects the overall layout of the interior and has a certain sense of depression, which is difficult to apply to families
[0004] Composite materials applied to the field of environmental protection, because they can not respond well to light, resulting in low environmental performance

preparation example Construction

[0031] The preparation method of polyethylene terephthalate modified photochromic agent comprises the following steps:

[0032] 1) Add terephthalic acid and ethylene glycol into the reactor, heat the reactor and stir it to carry out esterification reaction, generate esterification product, and cool to solid; the reaction temperature is 180-220°C; the reaction time is 1 -4 hours.

[0033] 2) Grinding the esterification product into powder to obtain the esterification product powder;

[0034] 3) The powder of the esterification product and the inorganic color-changing agent are fully mixed and then subjected to vacuum polycondensation reaction to prepare a polyethylene terephthalate modified photochromic agent. When the vacuum polycondensation reaction is carried out, the vacuum is kept stable in this application, and the polycondensation conditions of low vacuum in the early stage and high vacuum in the late stage cannot be used in some existing technologies.

Abstract

The invention relates to a high polymer composite material which at least contains photochromic fibers. In the technical scheme, a polyethylene glycol terephthalate modified photochromic agent is added into the high polymer composite material, and due to coating of the polyethylene glycol terephthalate, the distribution uniformity of the photochromic material in the high polymer composite materialis realized. Moreover, the photochromic agent is an inorganic reversible photochromic agent and realizes excellent ultraviolet photochromic property, and the protective property of the composite material on ultraviolet light is improved.
