Embodiment 1

[0016] A color-changing silica gel cup, the preparation method of which is as follows:

[0017] (1) Mixing: Stir component A and component B evenly in proportion, then put it into a vacuum machine to vacuum for 10-15 minutes, and discharge the air bubbles in the mixture;

[0018] (2) Casting mold;

[0019] (3) Vulcanization molding.

[0020] The A component is hydrated silicon dioxide with a mass percentage of 98-99%, and the B component is a mixture with a mass percentage of 1-2%.

[0021] The composition and parts by weight of the mixture of component B are:

[0022] Hydroxy acrylic resin, 65 parts; Butyl acetate, 18 parts; Silicone oil, 5 parts; Stearamide, 2 parts; Benzyl p-hydroxybenzoate, 3 parts; Crystal violet lactone, 3 parts; Ethanol, 15 parts; Ten parts Hexaol, 5 parts.

Embodiment 2

[0024] The difference with embodiment 1 is:

[0025] The composition and parts by weight of the mixture of component B are:

[0026] Hydroxy acrylic resin, 68 parts; Butyl acetate, 15 parts; Silicone oil, 4 parts; Stearamide, 1 part; Benzyl p-hydroxybenzoate, 2 parts; Crystal violet lactone, 2 parts; Ethanol, 10 parts; Ten parts Six alcohols, 8 parts.

Embodiment 3

[0028] The difference with embodiment 1 is:

[0029] The composition and parts by weight of the mixture of component B are:

[0030] Hydroxy acrylic resin, 70 parts; Butyl acetate, 10 parts; Silicone oil, 6 parts; Stearamide, 2 parts; Benzyl p-hydroxybenzoate, 4 parts; Crystal violet lactone, 4 parts; Ethanol, 20 parts; Ten parts Six alcohols, 7 parts.

Abstract

The invention relates to a color-changing silicone cup, the preparation raw materials of which is formed by an A constituent and a B constituent. The A constituent is hydrated silicon dioxide, which accounts for 98-99% by mass percentage; and the B constituent is a mixture, which accounts for 1-2% by mass percentage. The ingredients and parts by weight of the mixture are 60-70 parts of hydroxy acrylic resin, 10-20 parts of butyl acetate, 4-6 parts of silicone oil, 1-2 parts of stearamide, 2-4 parts of benzyl 4-hydroxybenzoate, 2-4 parts of crystal violet lactone, 10-20 parts of ethanol and 5-8 parts of cetanol. The crystal violet lactone is used as leuco dye, and the benzyl 4-hydroxybenzoate is used as a color developing agent, wherein the two ingredients are nontoxic raw materials; the benzyl 4-hydroxybenzoate is mostly used for food flavor; the crystal violet lactone is fast in color development and high in chroma; and sensitivity for thermoinduction is improved.

Description

technical field [0001] The invention belongs to the field of silica gel products, and relates to a cup made of silica gel, in particular to a color-changing silica gel cup. Background technique [0002] Silicone cup is a water cup made of food-grade silica gel. It is characterized by safety, non-toxicity, drop resistance, non-slip, and moderate hardness. Because it can be made into various colors and bright colors, it is very popular among young people. The silicone cup has good heat insulation performance. Even if you pour hot water into it, the temperature is not high. However, this advantage is also its disadvantage. People cannot distinguish the water temperature without feeling the temperature, and it is easy to be scalded by hot water. . [0003] Thermochromic material is a special functional material, which has the characteristic of changing color with temperature. The initial research on thermochromic materials is based on measuring the temperature and distribution...
