Problems solved by technology

However, a large amount of artificial synthetic additives will be added to the existing diatom mud coating, which makes the diatom mud coating easy to produce harmful substances, resulting in formaldehyde and air pollution. Stronger stains, prone to irreversible scarring, poor stain resistance
[0004] But the existing diatom mud is all mainly used for interior wall coatings, and has not been used in the field of automobile refinishing paint, mainly because the use environment of automobile refinishing paint is generally on the automobile of high-speed motion, and diatom mud has good Adsorption performance, it will absorb a lot of dust or other substances, making it difficult to clean

[0043] 1. Grind the diatom mud into a powder with a particle size <= 15um for later use.

[0044] 2. Premix resin base material 40 by weight; leveling agent 1; anti-sedimentation agent 10; part of IBAC (60% of its total weight) is pre-mixed and stirred under the mixer at 1200-1500 rpm for 10 -15min, then add matting powder 5; diatom mud 10, disperse evenly under the mixer at 1500-2000 rpm, then add BAC 10; and the remaining IBAC to adjust the viscosity to 30-60s, and the measurement condition is to apply 4# cup to get the product .

[0045] Put the above paint-coated panel (10×10cm) in the simulated car running road environment for 7 days, the surface occupies a lot of dust, clean the surface of the experimental panel with a dust-free cloth moistened with clean water, and it will be as clean as new.

Embodiment 5

[0047] 1. Grind the diatom mud into a powder with a particle size <= 15um for later use.

[0048] 2. Premix resin base material 50 by weight; leveling agent 0.1; anti-sedimentation agent 1; part of IBAC (80% of its total weight) is pre-mixed and stirred under the mixer at 1200-1500 rpm for 10 -15min, then add matting powder 5; diatom mud 5, disperse evenly under the mixer at 1500-2000 rpm, then add BAC 5; adjust the viscosity with the remaining IBAC to 30-60s, and the measurement condition is to apply 4# cup to get the product .

[0049] Put the above-mentioned paint-coated board (10×10cm) in a simulated car running road environment for 7 days, the surface occupies a lot of dust, clean the surface of the painted board with interior paint cleaner, and it will be as clean as new.

Abstract

The invention relates to a dust particle adsorption paint and a preparation method thereof. The preparation method includes: by weight, pre-mixing 40-50 parts of a resin matrix; 0.1-1 part of levelingagent; 1-10 parts of an anti-settling agent; and part of IBAC, then performing stirring in a stirrer at a rotating speed of 1200-1500r / min for 10-15min, and then adding 2-5 parts of extinction powderand 5-10 parts of diatom ooze, dispersing the substances uniformly in a stirrer at a rotating speed of 1500-2000r / min, then adding 5-10 parts of BAC, and the remaining IBAC to adjust the viscosity soas to obtain the product. Compared with the prior art, the paint disclosed by the invention has good dust adsorbability and storage stability, and meanwhile, the adsorption force can be increased ordecreased according to the requirements of different purposes so as to reach the purposes of convenient cleaning and continuous use, and the paint can be widely applicable to space for reducing dust particles in the air.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a dust particle adsorption coating and a preparation method thereof. Background technique [0002] At present, with the continuous development of industrialization, the increasing air pollution (such as PM2.5), and the continuous improvement of people's living standards, the pursuit of a healthier living environment. There is an increasing demand for products that meet people's needs for improving the living space environment. And coating is filled with every aspect in people's life, even more seems particularly important. [0003] Diatom mud is a kind of inorganic gelling substance as the main bonding material, diatom material as the main functional filler, the preparation of dry powder interior wall decoration coating material, has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen Ionic, fire retardant, wall self-cleaning, sterilizat...
