preparation example Construction

[0024] A preparation method of an environmentally friendly architectural paint, comprising the steps of:

[0025] S1. Weigh 5-8 parts of auxiliary agent, 3-6 parts of dispersant, 4-6 parts of defoamer, and 2-5 parts of wetting agent by weight and pour them into the mixer, and mix with 1 / 3 of the deionized Mix the water phase, stir at a constant speed of 350-450r / min for 15-35min, slowly add 20-30 parts of methyl methacrylate during the stirring process, disperse for a period of time, and obtain a mixed mixed solution;

[0026] S2. Add the mixed solution obtained in step S1 to 25-35 parts of tiger Piran plant extract, 18-25 parts of medical stone, 10-15 parts of hollow glass microspheres, 15-20 parts of diatomaceous earth, and 10 parts of titanium dioxide. -15 parts, disperse at high speed for 15-35min at a speed of 1500-2500r / min;

[0027] S4. Then reduce the speed to 400-900r / min, add 15-25 parts of low VOC pure acrylic emulsion, disperse evenly, and finally use 2-4 parts of...

Embodiment 1

[0029] S1. Weigh 6 parts of auxiliary agent, 5 parts of dispersant, 5 parts of defoamer, and 3 parts of wetting agent by weight into the mixer, mix with 1 / 3 of deionized water, and mix at 400r / min Stir at a constant speed at a constant speed for 23 minutes, slowly add 26 parts of methyl methacrylate during the stirring process, and disperse for a period of time to obtain a mixed mixed solution;

[0030] S2, add the mixed solution obtained in step S1 to 33 parts of tiger Piran plant extract, 23 parts of medical stone, 13 parts of hollow glass microspheres, 18 parts of diatomaceous earth, 14 parts of titanium dioxide, and the rotation speed is 2200r / min High-speed dispersion for 28 minutes;

[0031] S4. Then reduce the speed to 600r / min, add 22 parts of low VOC pure acrylic emulsion, disperse evenly, and finally use 3 parts of thickener to adjust the viscosity.

Embodiment 2

[0033] S1. Weigh 8 parts of auxiliary agent, 6 parts of dispersant, 6 parts of defoamer, and 5 parts of wetting agent by weight, pour them into the mixer, mix with 1 / 3 of deionized water, and mix at 450r / min Stir at a constant speed at a constant speed for 35 minutes, slowly add 30 parts of methyl methacrylate during the stirring process, and disperse for a period of time to obtain a mixed mixed solution;

[0034] S2. Add the mixed solution obtained in step S1 to 35 parts of tiger Piran plant extract, 25 parts of medical stone, 15 parts of hollow glass microspheres, 20 parts of diatomaceous earth, 15 parts of titanium dioxide, and the rotation speed is 2500r / min. High-speed dispersion for 35 minutes;

[0035] S4. Then reduce the speed to 900r / min, add 25 parts of low VOC pure acrylic emulsion, disperse evenly, and finally use 4 parts of thickener to adjust the viscosity.

Abstract

The invention discloses an environment-friendly building coating and a preparation method thereof. The environment-friendly building coating comprises 25-35 parts of sansevieria trifasciata prain plant extract, 20-30 parts of methyl methacrylate, 18-25 parts of medical stone, 10-15 parts of hollow glass beads, 15-20 parts of diatomaceous earth, 10-15 parts of titanium dioxide, 15-25 parts of low VOC pure acrylic emulsion, 2-4 parts of thickener, 5-8 parts of auxiliaries, 3-6 parts of dispersing agent, 4-6 parts of antifoaming agent, 2-5 parts of wetting agent and 15-25 parts of deionized water. According to the environment-friendly building coating, formaldehyde brought by indoor decoration can be removed, a formaldehyde removing function can be achieved without follow-up addition of functional materials, and a long-term effect and stability of coating formaldehyde removal are achieved. The environment-friendly building coating is good in sound absorption effect, safe and environmentally friendly, saves indoor space and can adjust indoor air humidity. When the air humidity is large, the pore wall and particularly wood fibers can adsorb a certain amount of moisture.

Description

technical field [0001] The invention relates to the technical field of architectural paint production, in particular to an environmentally friendly architectural paint and a preparation method thereof. Background technique [0002] With the rapid development of social production, energy and the environment have become two major issues that the whole society pays more and more attention to, thus putting forward higher requirements for energy saving and environmental protection. Today, the world is generally facing the crisis of increasing energy shortage. In order to reduce energy consumption, people have put forward higher requirements on the efficiency of energy use in all aspects of social production and life. Among them, in the construction field, energy-saving buildings are an effective way to improve the energy efficiency of buildings. [0003] Spraying thermal insulation coating on the exterior wall or interior wall of a building is a means of building energy saving...
