Description

Technical Field

It is widely used in interior wall decoration. Microcement art paint can not only meet the needs of different consumers in color, but also has a wide variety of styles, from simple to retro, from modern to traditional, all styles can be easily controlled.

[0003] The adhesion of some existing traditional inorganic microcement art paints is average. If the base construction is not properly handled, it will seriously affect the overall adhesion and decorative effects of the paint. Therefore, there is an urgent need for an inorganic microcement art paint and a preparation method thereof. Summary of the invention

[0010] By using nano-silica modified acrylic resin and acrylic modified alkyd resin to prepare the base paint, the chemical properties of nano-silica can effectively improve the overall high specific surface area and activity of the coating, so that the inorganic micro-cement art paint forms a denser microstructure during the curing process, further increasing the overall adhesion performance of the coating formed by the inorganic micro-cement art paint.

[0011] Preferably, the mass ratio of the additive to the adhesion enhancer is 1:(1.1-1.3).

[0012] Preferably, the inorganic filler includes at least one of quartz sand and microbeads.

[0013] Preferably, the particle size of the inorganic filler is 300-400 mesh.

[0014] According to another aspect of the present invention, there is provided a method for preparing an inorganic microcement art paint, comprising the following steps:

[0015] S1. Mix inorganic silicate cement, water-based resin and quartz sand, and irradiate them at 18 to 22° C. for 3 to 5 hours using ultraviolet irradiation equipment to obtain a cement matrix;

[0016] S2. Mix the cement matrix and inorganic filler, disperse and stir at a speed of 1500-2000 rpm for 2-4 hours, then add inorganic pigment and base paint, continue stirring at a speed of 2500-3500 rpm at 15-25°C, add adhesion enhancer during the stirring process, let it stand, and obtain inorganic micro-cement art paint.

[0019] In the present invention, inorganic silicate cement is selected as the basic material to improve the basic hardness and durability of the microcement paint, and polymer emulsion, nano-silicon dioxide and silane coupling agent are selected as reinforcing materials, and the addition of inorganic fillers can improve the coating to form a more dense microstructure during the curing process. The prepared inorganic microcement art paint has strong adhesion, so that the formed coating is more firm and not easy to fall off. DETAILED DESCRIPTION
