A kind of polyurethane water-based paint preparation process

Abstract

The invention relates to a polyurethane water-based paint preparation process, which uses a polyurethane water-based paint preparation equipment, which includes an installation box, a smoothing mechanism, a primary filter mechanism, a secondary filter mechanism, a separation mechanism and a receiving box. The installation box is a cylindrical hollow structure, the shaking mechanism is set on the upper end of the installation box, the primary filter mechanism is set on the upper side of the installation box, the separation mechanism is set in the installation box on the lower side of the primary filter mechanism, and the secondary filter is arranged circumferentially on the installation box. The outer side of the box, and the secondary filter mechanism are connected to the receiving box, the middle part of the lower end surface of the installation box is provided with a drive motor, and the lower side of the installation box is provided with a mounting frame; when the polyurethane water-based paint preparation equipment is used to prepare the polyurethane water-based paint , comprising the following steps: S1, pouring the paint; S2, shaking the paint evenly; S3, filtering the paint; S4, separating the paint; S5, filtering again; S6, blending the paint.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a preparation process of polyurethane water-based paint. Background technique [0002] Polyurethane water-based coating is a waterproof material with excellent mechanical properties such as high strength, high hardness, excellent fatigue resistance and good flexibility. At the same time, water is used instead of organic solvents as the dispersion medium, which is non-toxic, energy-saving and non-polluting. Environmental and other advantages, so polyurethane water-based coatings occupy an important position in the coatings market. During the preparation of polyurethane water-based coatings, it is necessary to mix and stir the raw materials to better integrate the pigment particles, binders and solvents. [0003] Yet there are following problems when polyurethane aqueous coating is prepared in prior art: [0004] 1. In the existing technology, after the raw materials of...

AI Technical Summary

Problems solved by technology

[0004] 1. In the existing technology, after stirring the raw materials of polyurethane water-based coatings, there may be incomplete mixing between raw materials, and various raw materials gather into groups, making it difficult to thoroughly stir

[0005] 2. In the existing technology, when stirring the raw materials of polyurethane water-based coatings, due to the presence of debris particles in the mixing machine, impurities are easily brought into the raw materials during the stirring process, which reduces the quality of preparing polyurethane water-based coatings.

[0006] 3. It is difficult to control the preparation concentration of the polyurethane water-based paint prepared after stirring the raw materials of the polyurethane water-based paint in the existing technology. For different items to be used to adapt to the polyurethane water-based paint, different concentrations of the polyurethane water-based paint are required. Therefore, the general preparation Polyurethane water-based coatings are difficult to meet specific use requirements
