Abstract

The invention relates to the technical field of heat-insulation thermal-insulation coating formulas for building exterior-walls, and specifically relates to an environment-friendly inorganic exterior-wall heat-insulation thermal-insulation coating and a preparation process thereof. The coating comprises the following components: a functional filler, a modified polymer emulsion, other pigments, auxiliaries, and water, wherein the functional filler is a mixed bead filler formed by compounding, and the modified polymer emulsion is a compound of silica sol and polymer emulsion. The invention provides the environment-friendly inorganic exterior-wall heat-insulation thermal-insulation coating which is prepared by adding formulas such as hollow ceramic beads or hollow glass beads with different components and different grain sizes, modified polymer emulsion, and auxiliaries; the coating has better heat-insulation thermal-insulation performance, a lower heat conduction coefficient, excellent comprehensive performances, convenience in construction, and coating thickness of 0.5-1mm; the coating is aqueous and pollution-free, safe and environment-friendly, and suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of heat-insulating and heat-insulating paint formulations for building exterior walls, in particular to a green inorganic heat-insulating paint for exterior walls and a preparation process thereof. Background technique [0002] With the increasing consumption of energy such as coal, oil, and natural gas, the problem of energy shortage has gradually become a bottleneck restricting the economic development of various countries. According to statistics, about one-third of energy consumption is in the construction field. Therefore, seeking and formulating effective energy-saving and thermal insulation methods is highly valued by energy control agencies in various countries. The vigorous development of thermal insulation coatings in the construction industry is a response to national energy-saving and thermal insulation measures. important way. As an important part of building energy-saving and heat-preservation...
