Embodiment 1

[0013] The color-changing solid glue stick is prepared from the following raw materials in proportion by weight: 55.0 parts of water; 25.0 parts of polyvinylpyrrolidone; 5.0 parts of styrene-acrylic emulsion; 15.0 parts of acrylic emulsion; 3.0 parts of sodium hydroxide; 1.0 parts of optical variable pigments; 15.0 parts of kaolin; 0.2 parts of butyl p-hydroxybenzoate.

[0014] Add water to the reaction equipment, add polyvinylpyrrolidone, styrene-acrylic emulsion, acrylic acid emulsion, and dextrin while stirring. After stirring evenly, start stirring and heat up to 90°C. Stir at a constant temperature of 90°C to dissolve completely. After stirring and dissolving completely, stir While adding propylene glycol and stearic acid and stirring evenly, adding sodium hydroxide while stirring and stirring to complete the reaction, adding optical variable pigments, kaolin and butyl p-hydroxybenzoate while stirring and stirring evenly. Static defoaming at a constant temperature of abou...

Embodiment 2

[0016] The color-changing solid glue stick is prepared from the following raw materials in parts by weight: 85.0 parts of water; 15.0 parts of polyvinylpyrrolidone; 10.0 parts of styrene-acrylic emulsion; 10.0 parts of acrylic acid emulsion; 0.5 parts of sodium hydroxide; 5.0 parts of optical variable pigments; 10.0 parts of calcium carbonate; 3.0 parts of butyl p-hydroxybenzoate.

[0017] Add water to the reaction equipment, add polyvinylpyrrolidone, styrene-acrylic emulsion, acrylic acid emulsion, and dextrin while stirring. After stirring evenly, start stirring and heat up to 85°C. Stir at a constant temperature of 85°C to dissolve completely. After stirring and dissolving completely, stir While adding glycerin and stearic acid and stirring evenly, adding sodium hydroxide while stirring and stirring to complete the reaction, adding optical variable pigments, calcium carbonate and butyl p-hydroxybenzoate while stirring and stirring evenly. Static defoaming at a constant temp...

Embodiment 3

[0019] The color-changing solid glue stick is prepared from the following raw materials in proportion by weight: 60 parts of water; 20 parts of polyvinylpyrrolidone; 8 parts of styrene-acrylic emulsion; 12 parts of acrylic emulsion; 8 parts of dextrin; 1 part of sodium hydroxide; 2 parts of optical variable pigment; 12 parts of kaolin; 1 part of butyl p-hydroxybenzoate.

[0020] Add water to the reaction equipment, add polyvinylpyrrolidone, styrene-acrylic emulsion, acrylic acid emulsion, and dextrin while stirring. After stirring evenly, start stirring and heat up to 87°C. Stir at a constant temperature of 87°C to dissolve completely. After stirring and dissolving completely, stir While adding glycerin and stearic acid and stirring evenly, adding sodium hydroxide while stirring and stirring to complete the reaction, adding optical variable pigments, kaolin and butyl p-hydroxybenzoate while stirring and stirring evenly. Static defoaming at a constant temperature of about 87°C,...
