Problems solved by technology

[0005] The first object of the present invention is to provide a bottom-surface-in-one coating, which can be upgraded to a bottom-surface-in-one coating by directly mixing a substance that can improve the gloss and fullness of the water-based coating with the primer, which solves the problems of the prior art. The formula design in the medium is cumbersome, and the technical problems of the performance of the bottom-surface integrated coating and the glossiness cannot be considered

Embodiment 1

[0075] The preparation method of the bottom-surface-integrated coating of the present embodiment comprises the following steps:

[0076] (1) Weigh the raw materials according to the weight ratio in the table

[0077]

[0078] (2) Mix the alkyd resin and the water-soluble acrylic resin evenly under the rotating speed of 800 rpm / min, add dispersant and defoamer, add 3000 mesh talcum powder and 1250 mesh barium sulfate, then add propylene glycol methyl ether, For the mixture of dipropylmethanol butyl ether and water, increase the stirring speed to 1500rpm / min, and stir at high speed for 30min;

[0079] (3) Reduce the stirring speed to 1000-1200rpm / min, add a pH regulator to the material obtained in step (2) to adjust the pH value to 8.0-8.5, and then add the remaining auxiliary agents and color paste (black pulp, white slurry), stirred at a rotating speed of 1000-1200rpm / min for 5-10min to obtain base material;

[0080] (4) Then take the base material, according to the weigh...

Abstract

The invention relates to the technical field of paint production, in particular to a bottom-surface-in-one paint, a preparation method thereof, a gloss adjustment method and application thereof. The bottom-surface-in-one coating includes 3-8 parts of acid resin, 25-50 parts of acrylic resin, 2-5 parts of talcum powder, 5-12 parts of barium sulfate, 1-3 parts of propylene glycol methyl ether, and 1-3 parts of dipropylmethanol butyl ether 2 parts, 0.2-4 parts of water, 15-20 parts of color paste, 3-9 parts of additives, 0.01-30 parts of polyaldehyde resin solution; wherein, the polyaldehyde resin solution is mainly dissolved in a composite solvent by polyaldehyde resin be made of. The present invention introduces polyaldehyde resin into the paint, designs and enhances the aesthetic value of the paint from the molecular structure level, and effectively improves the gloss and fullness of the primer. The polyaldehyde resin is used to make the bottom-surface-integrated paint have the advantages of primer and topcoat at the same time.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a bottom-surface-in-one paint, a preparation method thereof, a gloss adjustment method and application thereof. Background technique [0002] In mechanical production, painting is an essential process, and the traditional painting process is pretreatment-primer-putty-finish, this process not only wastes manpower, material resources, time and cost, but also uses In the process, the compatibility between primer, putty and topcoat should also be considered. The emergence of the bottom-surface-integrated paint has subverted this traditional painting process. It has the advantages of quick-drying primer, anti-rust, mildew-proof and high-gloss and high-fullness of the top coat. It only needs to go through a simple painting process. It meets the requirements, saves time and labor, and has broad application prospects. [0003] The gloss of the material is essentially the specu...
