Water-based 5G agglomerated stone imitation coating and preparation method thereof

Abstract

The invention relates to a water-based 5G agglomerated stone imitation coating and a preparation method thereof. The coating is composed of a pigment part, a granulation intermediate with lubrication, isolation and protection functions, and latex paint with film forming and weather resistance. The preparation method comprises the following steps: (1) preparing base paint; (2) preparing a granulation intermediate; (3) preparing latex paint; and (4) preparing the water-based 5G agglomerated stone imitation coating: mixing the base paint with color paste for color mixing to form a pigment part, then coating the pigment part with the granulation intermediate, performing granulation through a screen under pressure, then adding the latex paint, conducting mechanical stirring and uniform blending, and conducting standing for reaction to obtain the water-based 5G agglomerated stone imitation coating. Compared with the prior art, the stone imitation coating is specially used for replacing a conventional stone imitation coating in appearance, is different from water-based colorful building paint in structural composition, is not higher than the conventional stone imitation coating in engineering price, and is superior to both stone-like paint and water-based colorful building paint in cost performance.

Description

technical field [0001] The invention relates to the field of stone imitation paint, in particular to a water-based 5G granite stone imitation paint and a preparation method thereof. Background technique [0002] At present, when the decoration of building exterior walls adopts the paint coating method, although the latex paint containing elastic latex paint is still widely used, the market is gradually shrinking because of its monotonous appearance and poor durability. The appearance is like a stone, which is more upscale, and the durability is also significantly improved, so it has suddenly emerged and is in the ascendant. [0003] In the field of stone-like architectural coatings, the main products on the market are real stone paint and water-based colorful architectural paint. Real stone paint has a long history and a large volume. Many major defects have caused people to gradually give up this kind of paint. The current difficulties of real stone paint include: ① comple...

Problems solved by technology

[0002] At present, when the decoration of building exterior walls is painted, although latex paint containing elastic latex paint is still widely used, it is monotonous in appearance and durable Poor performance, the market is gradually shrinking, and stone-like architectural coatings, because of their stone-like appearance, are more upscale, and their durability is also significantly improved, so they have sprung up and are in the ascendant.

[0003]In the field of stone-like architectural coatings, the main products on the market are real stone paint and water-based colorful architectural paint. The quantity is large, and the operation of each link is smooth, and it is relatively mature, but many major defects exposed by it make people gradually begin to give up this kind of paint. The current difficulties of real stone paint include: ①Complicated construction, easy to bloom; ②Peeling phenomenon often occurs; ③ poor stain resistance; ④ easy to crack during drying and film formation; ⑤ easy to yellow; Heavy sand wastes resources and pollutes the environment; ⑨Stone mining and colored sand manufacturing seriously damage the environment, consumes a lot of energy, neither saves energy nor reduces emissions; ⑩The real stone paint market currently has serious overcapacity and fierce competition.

As a result, emulsions are not allowed, resulting in a serious decline in the overall quality of real stone paint on the market. The overall durability is not as good as ordinary elastic paint, or even worse than latex paint, so real stone paint is gradually eliminated.

[0004] Later, water-based colorful architectural coatings came into being. Because of their many advantages, they have gradually become the mainstream choice of stone-like coatings. High degree of modernization, and because of the unique stability problems of production and storage, there is a high technical threshold, and the project price is 10-50% higher than that of real stone paint projects.
