Abstract

The invention provides a preparation method of thermosensitive color-changing organic glass. The method comprises the following steps of 1 preparation of thermosensitive color-changing microcapsules, wherein crystal violet lactone, stearic acid and tetradecyl alcohol are weighed accurately, stirring and dissolving are conducted, an aqueous solution of Tween 80 is dropwise added, stirring is conducted for 2 h at the temperature of 70 DEG C, a solution A is obtained, methyl methacrylate and benzoyl peroxide are weighed, a stirring reaction is conducted for 30 min at the temperature of 80 DEG C, a solution B is obtained, the solution B is dropwise added into the solution A, reacting is conducted for 30-45 min at the temperature of 80 DEG C, filtering, water washing and drying are conducted, and the color-changing microcapsules are obtained; 2 preparation of thermosensitive color-changing organic glass, wherein methyl methacrylate and benzoyl peroxide are weighed, a stirring reaction is conducted for 30-60 min at the temperature of 85 DEG C, the color-changing microcapsules are added, stirring continues to be conducted for 5 min, rapid cooling is conducted to reach 50 DEG C, standing is conducted for 1 h, the temperature is increased to 70 DEG C, constant temperature treatment is conducted for 2 h, the temperature is increased to 100 DEG C, and constant temperature treatment is conducted for 2-3 h, and the color-changing organic glass is obtained. According to the method, the color-changing organic glass is obtained by conducting bulk polymerization on thermosensitive color-changing microcapsules polymethyl methacrylate in situ, and the product has the advantages of being sensitive in color changing and uniform in color and luster.

Description

technical field [0001] The invention belongs to the field of composite material preparation and relates to a preparation method of temperature-sensitive color-changing organic glass. Background technique [0002] Temperature-sensitive discoloration is a phenomenon that changes color according to the difference in temperature. This phenomenon can be used to make various products with temperature-sensitive discoloration. For example, temperature-sensitive discoloration materials can be used to build plant growth sheds, which can achieve different temperatures. Different lighting effects facilitate the selection of lighting for plants and have certain practicability. Among them, color-changing plexiglass is a common color-changing material, but its preparation method is not yet mature, the manufacturing cost is high, and the temperature-sensitive color-changing effect is general. [0003] In view of this, the present invention performs bulk polymerization of color-changing mic...
