Electrostatic adsorption dust-free coating for laboratory as well as preparation method and use method of electrostatic adsorption dust-free coating

Abstract

The invention relates to the field of coatings, in particular to an electrostatic adsorption dust-free coating for a laboratory and a preparation and use method thereof.The electrostatic adsorption dust-free coating is prepared from, by weight, 15-20 parts of water, 30-40 parts of bio-based polyacrylate emulsion, 0.5-5 parts of conductive fibers, 0.5-5 parts of graphite powder, 9-11 parts of coarse whiting, 19-21 parts of titanium dioxide and 0.5-5 parts of coalescing agent; the coating is prepared by stirring all the components in a stirring device according to the adding sequence. According to the scheme, the coating is smeared on a wall, dust in air can be adsorbed, floating of the dust in the air is greatly reduced, and a great auxiliary effect is achieved for treatment of the dust in the air in a laboratory.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an electrostatic adsorption dust-free coating for a laboratory and a preparation and application method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil or emulsion, with or without adding pigments, fillers, and adding corresponding additives , a viscous liquid prepared with organic solvents or water. [0003] Laboratories generally have dust-proof regulations, and suspended particles in the air will have adverse effects on the optical system and electronic system of the instrument. If the instrument or the surrounding environment is full of dust, the dust will be scattered on the surface of the optical components of the instrument, which will not only increase the stray light of the instrument, but also reduce the light t...

AI Technical Summary

Problems solved by technology

If the instrument or the surrounding environment is full of dust, the dust will be scattered on the surface of the optical components of the instrument, which will not only increase the stray light of the instrument, but also reduce the light transmittance and reflectivity of the optical instrument, and eventually lead to a decrease in the sensitivity of the instrument

Dust can also cause bypass, short circuit and poor contact of electronic components, resulting in poor contact between parts and poor electrical insulation performance due to adsorption, which affects the normal use of the instrument

[0004] Most of the dust in the laboratory floats in the air, and the dust in the air is not easy to clean. Although the laboratory is equipped with dust-proof and dust-filtering equipment, the dust-proof and dust-filtering equipment has a limited range of dust treatment after all. Dusty equipment has a limited treatment effect on dust and cannot further reduce the dust in the air
