Environment-friendly water-based paint and preparation method thereof

Abstract

The invention discloses an environment-friendly water-based paint and a preparation method thereof, which belong to the technical field of water-based paints. A proper amount of polyethylene glycol isadded into the mixed material after the materials required to be added every time are mixed for a small period of time, so that the dispersion rate of the mixed solution is increased while certain premixing time exists among the added materials, furthermore, the time for mixing and stirring the mixed solution can be effectively shortened, part of energy consumption generated in the working process of the reaction kettle is saved, the preparation time of the water-based paint is shortened, polyethylene glycol has no toxicity or irritation and is not prone to harm to the environment and human beings, and meanwhile, after the mixed solution is stirred, the particle detection rod is arranged, so that a worker can judge whether the mixed solution is uniformly dispersed without particles by contacting the particle detection rod with the mixed solution and observing whether particles are adsorbed on the colored rubber mud or not, and compared with naked eye observation, the observation result is more direct and accurate.

Description

technical field [0001] The invention relates to the technical field of water-based paint, and more specifically relates to an environment-friendly water-based paint and a preparation method thereof. Background technique [0002] Traditional paints use vegetable oils and synthetic resins as the main film-forming substances, supplemented by various additives and pigments. When used, they need to be diluted with organic solvents such as toluene and xylene. The base material is small molecules in synthetic resins that are easily absorbed by the human body. damage, and the solvents are toluene and xylene, which are even more pathogenic substances. It also needs to consume a lot of energy and materials when producing these solvents, and discharge a large amount of waste residue and toxic gases, which is extremely unfavorable to the environment. Water-based paint uses a variety of polymer resins as the base material, water as the dispersion medium, and special additives are added t...

AI Technical Summary

Problems solved by technology

[0003] In the existing environment-friendly water-based paint preparation process, a dispersant is usually added to make the mixing of the mixed solution more uniform and particle-free. The addition method is usually to add after the main base material of the water-based paint is mixed and stirred evenly. In this case, the mixing The stirring efficiency of the solution is low, and when the mixed solution is stirred, it is usually observed by the staff with the naked eye whether the mixed solution is evenly dispersed and free of particles, and the error is large
