Problems solved by technology

It can be seen that in the prior art, polymer resin is generally used as the matrix, its strength and hydrophobicity are not good, it is easy to cause the wall to absorb moisture, and no flame retardant is added to prevent the spread of fire
Most of the solvents are non-polar solvents such as toluene or acetone, which are very poor in environmental protection.

Abstract

The invention discloses an environment-friendly temperature-variable interior wall paint, and a preparation method thereof. The environment-friendly temperature-variable interior wall paint comprises,by weight, 40 to 50 parts of a matrix, 20 to 40 parts of a solvent, 1 to 10 parts of a thermochromic powder, 3 to 6 parts of a flame retardant, 3 to 6 parts of a lubricant, and 5 to 10 parts of a dispersing aid. The environment-friendly temperature-variable interior wall paint is prepared through four following steps: preparation of a thermochromic powder dispersion, matrix pre-curing, wet coating preparation, and wet coating curing. Compared with the prior art, the advantages are that the environment-friendly temperature-variable interior wall paint possesses strong light sensitivity, the lubricant capable of improving touch feel is added, so that excellent touch feel comfortability is achieved; excellent strength and hydrophobicity are achieved; the environment-friendly temperature-variable interior wall paint is no-toxic, is safe, is friendly to the environment, and is a novel functional paint with both the advantages of temperature variable paint and common paint; and no pollutionis caused.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly temperature-changing interior wall coating and a preparation method thereof. Background technique [0002] Temperature-changing material is a new material developed in recent years, which uses temperature difference to control color change. The temperature-changing material is essentially a microcapsule pigment that changes color as the temperature rises and falls. It is colored at low temperature and colorless at high temperature. Its color can be specified at standard temperature. Each color can be mixed with each other, and other dyes or pigments can also be added to adjust the color. The use temperature is -15-70°C. [0003] Take turkey blue and background yellow at 22°C as an example. When the temperature is lower than 22°C, the color is emerald green, a mixed color formed by temperature-sensitive turkey blue plus yellow. When the temperature is h...
