Problems solved by technology

[0003] Although these fibers have the above-mentioned respective characteristics, there are certain application limitations in use. 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 light-shielding performance. Affecting light, especially absorbing too much light, causing the fabric to heat up and affecting the use, if it is applied to the field of curtains, especially the morning and evening of the time cannot be judged through the curtains, and the shading performance is determined by the thickness and color of the curtain fabric. Realized, 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] Fibers applied to the field of environmental protection, because they cannot respond well to light, lead to low environmental performance

preparation example Construction

[0038] The preparation method of described polymethyl methacrylate modified photochromic agent, comprises the following steps:

[0039] 1) Add methyl methacrylate monomer and ethanol into the reactor, after stirring, the methyl methacrylate is completely dissolved in ethanol, add inorganic discoloration agent and organic discoloration agent, continue stirring and heat up to 60°C -80°C, then add the initiator BPO ethanol solution, stop heating and keep stirring for 1-2 hours, and gradually cool to solid;

[0040] 2) Grinding the above solid into powder to obtain a polymethyl methacrylate modified photochromic agent.

[0041] The polymethyl methacrylate modified photochromic agent is a shell-core structure with the photochromic agent as the core and a polymethyl methacrylate shell. The shell-core structure can ensure the stability with the polymer fiber. Combine and distribute evenly.

Abstract

The invention relates to an ultraviolet-resistant polychromatic fiber. The polychromatic fiber at least comprises a photochromic fiber. In the technical scheme, a polymethyl methacrylate modified photochromic agent is added in a polymer filer, the distribution uniformity of a photochromic material in the polymer fiber is realized due to the coating of polymethyl methacrylate, and the photochromicagent not only comprises an inorganic reversible photochromic agent, but also comprises an organic photochromic agent, so that the good ultraviolet photochromic property is achieved, and the protective performance of the fiber to ultraviolet rays is improved. The fiber can have a relatively good ultraviolet-resistant function if being applied to a textile fabric and has a relatively good protecting effect for damage caused by the ultraviolet rays if being applied to the field of environment friendliness; and on the other hand, if the fiber is applied to the field of solar energy, the utilization ratio of the solar energy can be increased, and the utilization ratio of the solar energy can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of macromolecular materials, and in particular refers to a color-changing fiber with ultraviolet protection and a corresponding change in the color of the fiber through the change of light. Background technique [0002] In the prior art, there are many types of fibers, and the uses of fibers are also very wide, including textile fields, optical fiber fields, environmental protection fields, and biological fields. [0003] Although these fibers have the above-mentioned respective characteristics, there are certain application limitations in use. For example, in the textile field, the fabric is too thin, and its light-shielding performance is not good. Affecting light, especially absorbing too much light, causing the fabric to heat up and affecting the use, if it is applied to the field of curtains, especially the morning and evening of the time cannot be judged through the curtains, and the shading performanc...
