Preparation process of waterborne coating

Abstract

The invention relates to a preparation process of waterborne coating. The preparation process comprises the following specific steps of base material selection, first-time stirring, grinding treatment, auxiliary material selection, second-time stirring, filtration and screening, detecting, packaging and other procedures. According to the preparation process, the problems that in the production andmanufacturing process of existing waterborne coating, raw materials for manufacturing the waterborne coating need to be filtered and screened manually, smell emitted in the waterborne coating causeshuman body discomfort, the raw materials are filtered through manual control, consequently substandard raw material particles are prone to being mixed, the using effect of the waterborne coating is affected, the size of the raw material particles has the precise requirements, when the raw materials are filtered manually through filtering tools, sieving holes of the filtering tools are prone to being blocked by the large particles, the raw material filtering efficiency is affected, the waterborne coating manufacturing time is affected, when the filtering tools are controlled manually for sieving and filtering the raw materials, the raw materials are prone to being spilled in the jolting process, the closed filtering tools are selected, and consequently, clearing is troublesome after work can be solved.

Description

technical field [0001] The invention relates to the technical field of production of water-based paints, in particular to a preparation process of water-based paints. Background technique [0002] In the process of production and packaging, water-based paints need to go through processes such as material selection, stirring, crushing and grinding, secondary feeding, secondary stirring, filtration and screening, testing and packaging. The processing of each process directly affects the final product of water-based paints. Effect, especially the process of filtration and sieving. Filtration and sieving needs to strictly control the particles of raw materials for making water-based paints. Through sieving and filtration, the qualified water-based paint particles are collected, and the particles that do not meet the standards are filtered out so as not to affect the overall water-based paint. Effect. [0003] In the production process of existing water-based paints, it is neces...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a preparation process for water-based paints, which can solve the problem that existing water-based paints need to manually filter and screen the raw materials for making water-based paints in the production process, and the odor emitted in the water-based paints will cause The human body is uncomfortable, manual control of filtering raw materials may easily lead to the mixing of substandard raw material particles, which will affect the use effect of water-based coatings. The size of raw material particles has precise requirements. When manually filtering raw materials with the help of filtering tools, larger particles will easily cause filtration The sieving hole of the tool is blocked, which affects the efficiency of raw material filtration and the production time of water-based paint, and the manual control of the filtering tool to sieve and filter the raw material is easy to spill the raw material during the bumpy process. Choose a closed filtering tool and clean it after the work is over. Trouble, high labor intensity and low work efficiency
