Preparation technology of environment-friendly waterborne industrial paint with high salt fog resistance and high anti-corrosion and anti-rust performance

Abstract

The invention relates to the technical field of industrial paint production, and discloses a preparation technology of environment-friendly waterborne industrial paint with high salt fog resistance and high anti-corrosion and anti-rust performance. A preparation method of the environment-friendly waterborne industrial paint comprises the following steps: mixing deionized water, a dispersing agentand a defoaming agent together according to a certain mass ratio, putting into a dispersing tank, and stirring, wherein the stirring speed of a dispersing machine is 600-800 rpm and the stirring timeis 10-15 min; putting an anti-rust pigment, TXL, aluminum phosphate and mica powder into the dispersing tank, and uniformly stirring to obtain a target slurry, wherein the stirring speed of the dispersing machine is 650-850 rpm and the stirring time is 20-25 min; conveying the obtained slurry into a grinder through a diaphragm pump, grinding till the fineness is 15-30 micrometers, and after completion of grinding, continuing putting into the dispersing tank; and putting acrylic resin, a wetting agent and propylene glycol into the dispersing tank, and dispersing for 30 min by stirring at a rotation speed of 600 rpm. By the preparation technology of the environment-friendly waterborne industrial paint with high salt fog resistance and high anti-corrosion and anti-rust performance, the industrial paint not only has strong anti-corrosion performance, but also is environment-friendly and healthy.

Description

technical field [0001] The invention relates to the technical field of industrial paint production, in particular to a preparation process of an environmentally friendly water-based industrial paint with high salt spray, heavy corrosion and rust prevention. Background technique [0002] Water-based paint is a technology developed in the 1960s. It is a general term for a class of paint that uses water as a solvent or as a dispersion medium. It can be roughly divided into water-soluble paint, water-diluted paint, and water-dispersible paint (latex paint). paint) 3 types. Coatings using water as a solvent not only save a lot of organic material resources and energy, but also reduce the discharge of organic solvents. With the enhancement of people's environmental awareness, the use of water-based coatings is increasing year by year, which has become the mainstream direction of the development of the modern coatings industry. [0003] At present, the anti-corrosion performance (...
