Problems solved by technology

However, powdered calcium carbonate is usually used. Due to the influence of its surface space effect, the particle size is small and easy to agglomerate and stratify. It is difficult to effectively disperse into the fluid, it is difficult to control the dispersion process, and it is difficult to fully exert its performance. It has greatly affected the popularization and use of nano-calcium carbonate

Abstract

The invention belongs to the field of chemical industry, and in particular relates to a water-based high-elastic thermal insulation coating using nano-scale calcium carbonate water slurry and a preparation method thereof. The water-based high-elastic thermal insulation coating of the present invention is composed of the following raw materials in mass fractions: 30%-40% of the main resin emulsion, 10-20% of the pigment, 40%-45% of the inorganic filler, and 0.5%-3 of the flame retardant %, dispersant 0.5%-1%, leveling agent 0.1%-0.8%, defoamer 0.1%-0.5%, thickener 0.1%-0.5%, anti-flash rust agent 0.1%-0.3%, thixotropic agent 0.1%‑0.2%, neutralizer 0.1%‑0.5%, anti-sedimentation agent 0.5‑1.0%. The water-based highly elastic thermal insulation coating has small thermal conductivity, stable thermal insulation performance, strong radiation resistance, good air permeability, good adhesion, stable structure and good weather resistance.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a water-based high-elastic thermal insulation coating using nano-scale calcium carbonate water slurry and a preparation method thereof. Background technique [0002] Nano-calcium carbonate is a new type of ultra-fine solid powder material developed in the 1980s, with a particle size between 0.01-0.1 μm. Due to the ultra-fine size of nano-calcium carbonate particles, its crystal structure and surface electronic structure change, resulting in quantum size effect, small size effect, surface effect and macroscopic quantum effect that ordinary calcium carbonate does not have. [0003] Calcium carbonate can be used as a pigment filler, which has the advantages of fineness, uniformity, high whiteness, and good optical properties. Anti-sedimentation effect, after the paint is made, the whiteness of the paint film increases, the gloss is high, and the hiding power does not de...
