[0005] In order to solve the problem that the existing primer must be polished before it can be recoated, which affects the fullness, the polishing process will cost extra manpower and work hours, and reduce the construction efficiency. The present invention provides a non-grinding, recoatable high-gloss white The production process of the topcoat is simple, and it can be recoated directly without grinding, which saves a lot of manpower and time and improves production efficiency

Embodiment 1
[0019] The ratio of each raw material consumption is as follows:
[0020]
[0021] The process steps are as follows:
[0022] (1) Put component A into the dispersion cylinder, adjust the speed to 1280r / min, and disperse at high speed for 30 minutes;
[0023] (2) Check the fineness. When the fineness is ≦15μm, adjust the speed to 800r / min, put in component B, and stir for 10 minutes;
[0024] (3) Adjust the rotation speed to 350r / min, then add component C, and stir at low speed for 5 minutes.

[0026] The ratio of each raw material consumption is as follows:
[0027]
[0028] The process steps are as follows:
[0029] (1) Put component A into the dispersion cylinder, adjust the speed to 1450r / min, and disperse at high speed for 30 minutes;
[0030] (2) Check the fineness. When the fineness is ≦15μm, adjust the speed to 800r / min, put in component B, and stir for 10 minutes;
[0031] (3) Adjust the rotation speed to 380r / min, then add component C, and stir at low speed for 5 minutes.
[0032] The relevant characteristic index of the white finish paint obtained in the above-mentioned embodiment is as follows:
[0033] Index item specific indicators Gloss 100-101 hardness HB-H Fullness excellent Recoatability (no sanding) excellent mirror effect excellent Adhesion between layers Level 0-1
[0034] It can be seen from the above examples that the advantages of the present invention are: (1) the high...

Abstract
The invention discloses a processing technique of polish-free recoating-available high-light white paint. The processing technique of the invention comprises the following steps: putting a component A (including high-hydroxyl value synthetic fatty acid resin 63, rutile titanium dioxide 30, a solvent 3 and a dispersant 1) into a dispersing cylinder, adjusting rotate speed to 1000-1500r / min to disperse at a high speed for 30 minutes, detecting degree of fineness, adjusting rotate speed to 800r / min when the degree of fineness is lower or equal to 15 mu m, putting a component B (including an antifoam agent 0.2, special acrylate 0.2, a levelling agent 0.02, a special fluorine-containing levelling agent 0.2, a surfactant 0.2, and a catalyst 0.2) into a dispersing cylinder, stirring for 10 minute, adjusting rotate speed to 300-400r / min, then adding a component C (including butyl acetate 2-3) and stirring at a low speed for 5 minutes. The processing technique is characterized by simper construction technique, direct recoating without polish, saving of plenty of manpower and time and raised production efficiency.
Description
technical field [0001] The invention relates to the field of preparation of high-end furniture wood lacquer, in particular to a production process of a non-grinding, recoatable high-gloss white finish. Background technique [0002] At present, the demand for high-grade bright white topcoat with high fullness, high gloss and high mirror effect is increasing day by day, which is mainly used in the field of high-end furniture wood lacquer. However, most of the existing paints must be polished before they can be reapplied or varnished, and during the construction and polishing process, there will be traces on the surface of the paint film, which has a great impact on the fullness of the paint film. Therefore, the aesthetics of the furniture should be considered first, and the polishing process will cost extra manpower and working hours, which reduces the construction efficiency and increases the cost of the enterprise. [0003] In the Chinese patent with the application number ...
