Water-in-water multicolor paint preparation method capable of high-speed slicing and granulation and paint prepared by method

Abstract

The invention discloses a water-in-water multicolor paint preparation method capable of high-speed slicing and granulation. The preparation process comprises the following steps: preparing an 8% protective glue solution; 2. preparing a basic paint; 3. preparing a basic color paint; 4. preparing a multicolor particle solution; and 5. preparing the water-in-water multicolor paint finished product. After the color matching is carried out on the basic paint, the 8% protective glue solution is utilized to perform system reinforcement; and in the granulation and slicing process, the 8% protective glue solution and a hydrophobic modified anionic surfactant are premixed, so that the negative-valence ions in the anionic surfactant sufficiently capture cations on the nano modified magnesium lithium sodium silicate mineral salt molecule surface to form a series of strict film structures, thereby eliminating the risk of rejection caused by color bleeding, fusion and thickening since colored particles can not be completely coated in time. Thus, the obtained water-in-water multicolor paint has the advantages of excellent mechanical strength, excellent toughness and high spraying efficiency. The invention also discloses a composition of the water-in-water multicolor paint.

Description

technical field [0001] The invention relates to a functional coating for architectural decoration, in particular to a preparation method and coating for a water-in-water multicolor coating capable of high-speed slicing and granulation. Background technique [0002] Among modern architectural wall decoration materials, marble has always occupied an important position in high-end wall decoration because of its durability, stain resistance, natural color, natural texture, and brilliant colors. [0003] However, natural marble is limited by mineral deposits, and excessive mining of marble mines will cause serious soil erosion and environmental pollution. In severe cases, it will affect the geological structure of the mining site, causing geological disasters such as landslides, mudslides, and subsidence. Local government departments strictly control its mining volume. , leading to high marble prices. Due to the large weight of marble, when decorating marble on the wall, it is u...

Problems solved by technology

[0005] At present, water-in-water multi-color coatings are not resistant to high-speed shearing due to the limitation of their formula system and process steps. Under high-speed shearing, the stability of the system will be destroyed, resulting in bleeding. In severe cases, the system will turn into paste and be completely scrapped.

In the prior art, water-in-water colorful paint slice granulation methods mostly adopt low-speed screen granulation, or disc granulation with a controlled rotating speed below 400 rpm, so that when very small particles (such as sesame grains) are needed, only Gradual granulation can be adopted, the granulation time is long, the energy consumption is high, which seriously affects the production progress, and the degree of simulation is difficult to guarantee

At present, the mechanical strength of the water-in-water multi-color paint produced by the existing formula system and preparation technology is low, and only 1.5-3.5kg / cm can be used. 3 If the air pressure is too high (4~5kg / cm2) to spray, the spraying efficiency is low. 3 ) will turn into a paste with no marbling effect
