Problems solved by technology

This type of coating is used as an exterior wall. Due to the high reflectivity of nano-titanium dioxide to sunlight, it can achieve the effect of heat insulation. However, due to the use of more fillers, the prepared coating has a large specificity and high thermal conductivity, so it cannot be used as Insulation paint for interior walls

Abstract

The invention discloses a building thermal insulation material for interior walls. The raw materials of the thermal insulation coating include fluorinated epoxy resin, 3-diethylaminopropylamine, bismaleimide, acryl boric acid ortho Di-tertiary alcohol ester, foam glass, ethylene-vinyl acetate copolymer, 3,3'-(p-phenylene oxide)bis(2,4,5-triphenyl)cyclopentadienone, polyazelaic anhydride, Water, dispersant, thickener, defoamer, wetting agent, antifungal agent; used in building interior wall insulation effect is obvious, with flame resistance, weather resistance, small specific gravity, small thermal conductivity, good bonding performance , not easy to fall off, good toughness, while reducing the density of the coating, reducing the thermal conductivity of the coating, increasing the light reflectivity of the coating, and improving the heat insulation effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to building thermal insulation materials for interior walls. Background technique [0002] Thermal insulation coating is a new type of thermal insulation material, a coating that achieves thermal insulation through low thermal conductivity and high thermal resistance. The product is made of high-quality natural minerals with chemical additives and high-temperature adhesives, and is manufactured through pulping, molding, shaping, drying, finished products, and packaging. With the development of the world economy and the improvement of people's quality of life, energy consumption is increasing, and energy determines the lifeline of the national economy, so energy competition is becoming increasingly fierce, and energy conservation issues are also being paid more attention to. Building thermal insulation is an important aspect of saving energy and improving the living and use functio...
