Preparation method of wet-jet wet waterborne coating

Abstract

The invention discloses a preparation method of a wet-jet wet waterborne coating, and belongs to the field of preparation of coatings. The preparation method comprises preparation of primer and preparation of finishing coat. The primer is prepared by a method comprising the following steps: A, raw material preparation: adding part of raw materials during stirring and uniformly grinding the raw materials into materials of which the fineness is smaller than 10 micrometers; and B, adding the rest of raw materials in the mixture while stirring, and after uniformly stirring, filtering to obtain theprimer. The finishing coat is prepared by a method comprising the following steps: a, raw material preparation: adding part of raw materials while stirring and uniformly stirring and grinding the rawmaterials into materials of which the fineness is smaller than 10 micrometers; and b, adding the rest of the raw materials in the mixture while stirring, and after stirring uniformly, filtering to obtain the finishing coat. The shortcomings that in the prior art, a waterborne coating is difficult to wet by wet-jet and the production efficiency is low are overcome, a wet-jet wet process can be realized effectively, therefore, the production efficiency is improved, and the production energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of paint preparation, and more specifically, relates to a preparation method of a wet sprayable water-based paint. Background technique [0002] In industrial production, there are many products that need to be sprayed on the surface due to the use requirements. Coating coating is an indispensable process requirement. At present, traditional solvent-based coatings are more common in the market, but with the strict requirements of the current national environmental protection policy , water-based low-temperature coating products with low VOC and low energy consumption have emerged as the times require, gradually replacing traditional solvent-based coatings, and are comparable to solvent-based coatings in terms of general construction and gloss leveling. Spray wet to achieve the coating and baking process of two coatings and one baking, which greatly reduces production energy consumption. However, in the cons...
