Abstract

The invention discloses a water-based marble-imitated coating and belongs to the technical field of coatings. The water-based marble-imitated coating is prepared from, by weight, 3.5-5.5 parts of hydroxyethyl cellulose, 3.5-5.5 parts of a multifunctional additive, 0.5-2.0 parts of a wetting agent, 1.5-2.5 parts of a defoaming agent, 8.5-10.5 parts of ethanediol, 18-20 parts of a coalescing agent, 6-10 parts of a thickening agent, 350-450 parts of a silicone acrylic emulsion, 2.5-4.5 parts of a flatting agent, 2.0-3.0 parts of an anti-precipitant, 10-20 parts of a bacteriostatic agent, 15-30 parts of a moss-resistant agent, 200-300 parts of colorful slices and 200-300 parts of water. The water-based marble-imitated coating is excellent in antibacterial effect and obvious in moss-resistant effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a water-based imitation marble coating and a preparation method thereof. Background technique [0002] Granite and marble are favored by owners for their solemn texture, durable quality and various colors. However, the shortcomings of granite and marble are also obvious. One is the high price, the other is the complicated construction, and the third is the safety problem caused by shedding, which makes many users discouraged. Water-based imitation marble coatings have emerged as the times require. However, general water-based imitation marble coatings, because It has no antibacterial effect, and the anti-moss is not ideal, which will affect the appearance after the growth of mold and moss, and also affect the durability of the paint. At present, there are many studies on water-based coatings, and there are many disclosures in patent documents. ...
