Problems solved by technology

According to the investigation and comparative analysis, the hollow glass microbead type exterior wall thermal insulation coating has the following defects: 1. The paint film is thick (the dry film is more than 200 μm), and the paint consumption is large; 2. The surface of the paint film is porous and the density of the paint film is not enough. , leading to poor water resistance and poor stain resistance of the paint film. 3. The storage period of the finished paint is short. Generally, after one month, the viscosity becomes larger, thickens, and becomes a paste, which affects the construction

Abstract

The invention discloses a heat reflection heat insulation coating for an outer wall. The heat reflection heat insulation coating is characterized by comprising the components in percentage by weight: 40 to 50 percent of film formation material, 29 to 38.5 percent of pigment and filler, 1 to 1.5 percent of monocrystalline silicon powder, 3 to 5 percent of aid, and 10 to 22 percent of deionized water, wherein the film formation material comprises water-based fluorocarbon emulsion and elastic emulsion; the pigment and filler comprises one or more of rutile titanium white, mica powder, kieselguhr, and superfine triple superphosphate; and the aid comprises one or more of dispersing agent, flatting agent, antifoaming agent, preservative, thickener, film formation aid, and anti-freezing agent. The coating has the characteristics of a building heat insulation material and a building coating, the heat insulation function and excellent performance of a coating, and is a novel heat insulation and energy-saving coating which has good performance, high applicability, and highest technical content in the field of heat insulation of modern buildings.

Description

technical field [0001] The invention relates to a heat-insulating paint, in particular to a heat-reflecting heat-insulating paint for exterior walls that can be thinly coated using a new type of heat-insulating material. Background technique [0002] At present, building exterior walls generally use hollow glass microbead type exterior wall heat-insulating coatings, such as a water-based building heat-insulating coating with the Chinese Patent Publication No. CN101429369. Obtained, its main components are in parts by weight: 40-50 parts of synthetic emulsion, 10-29 parts of deionized water, 1-3 parts of propylene glycol, 0.5-1.5 parts of alcohol ester-12, 15-25 parts of titanium dioxide, vitrified micro 3-15 parts of beads, 15-25 parts of metal oxide powder, 0.1-1 part of fungicide, 0.5-1.2 parts of dispersant, 0.03-0.08 part of wetting agent, 0.1-1 part of defoamer, 0.1 part of leveling agent -1 part, thickener 1-2 parts, ammonia water 0.1-1 part. Another example is a kin...
