Color-changing coating and preparation system and method thereof

Abstract

The invention discloses a color-changing coating and a preparation system and preparation method thereof. The color-changing coating is composed of the following components in parts by weight: octyldodecanedioate phthalate, tribasic lead sulfate, polyaluminium chloride, barium carbonate, propylene glycol phenyl ether, water, a thickener and a discoloring agent according to a ratio of (10-20): (1-3): (2-5): (5-8): (7-12): (30-90): (3-5): (2-5), the thickener is composed of cyclohexane, polyvinyl alcohol, hydroxyethyl cellulose and esterified pectin liquid, and the discoloring agent is composedof methyl methacrylate, zinc phosphate, methyl violet and phenolphthalein. The method comprises the following steps: 1, respectively adding the raw material components of the thickener and the raw material components of the color-changing agent into two movable stirring pipes, and adding the rest raw material components into a stirring cavity, 2, stirring the raw materials, 3, enabling the mixtureto flow into a stirring cavity, and continuously mixing and stirring with the raw materials in the stirring cavity, and 4, completely stirring all the raw materials in a stirring cavity formed by a stirring rectangular pipe and a stirring semicircular cylinder, so that a coating is obtained, discharging the coating through a discharging pipe, and collecting it.

Description

technical field [0001] The invention relates to the field of paint processing, in particular to a color-changing paint, a preparation system and a preparation method thereof. Background technique [0002] At present, the interior walls of buildings are generally painted with paint, which can be well bonded to the base material and form a complete and tough protective film when painted on the surface of the object. Architectural paints have decorative, protective and habitability improvement functions. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. For some buildings that need to clearly understand temperature changes, temperature-sensitive color-changing paints are often used to coat the interior walls, so as to quickly understand the temperature changes in the house through different colors and avoid losses. During the production and processing of color-c...

For some buildings that need to clearly understand temperature changes, temperature-sensitive color-changing paints are often used to coat the interior walls, so as to quickly understand the temperature changes in the house through different colors and avoid losses. During the production and processing of color-changing paints, there is often uneven mixing. Phenomenon that affects the quality of the paint
