Aqueous double-component inner wall heat-insulation coating

Abstract

The invention relates to an aqueous double-component inner wall heat-insulation coating. The aqueous double-component inner wall heat-insulation coating is characterized by being prepared from a component A and a component B, wherein the formula of the component A is as follows: 20-25 parts of styrene-acrylic emulsion, 20-25 parts of phenolic resin, 5-10 parts of dispersing agent, 6-8 parts of glycol and glycerol, 10-20 parts of filler, and 5-10 parts of infrared reflecting pigment with the refractive index of more than 2.0 and the particle size of not less than 1 micron, doped semiconductor and metal powder; the component B comprises 6-10 parts of polyisocyanate curing agent; the aqueous double-component inner wall heat-insulation coating is prepared through the following steps: adding the component A to a container according to the formula, sequentially adding deionized water, a filler and an adjuvant, dispersing for 20-30 minutes at high speed, adding the water-dispersibility polyisocyanate curing agent according to the certain proportion, and fully stirring to obtain the aqueous double-component inner wall heat-insulation coating.

Description

Technical field [0001] The invention belongs to the technical field of coatings and paints, in particular to a water-based two-component interior wall thermal insulation coating. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based paints include water-soluble paints, water-reducible paints, and water-dispersible paints. Water-soluble paints are water-soluble resins as the film-forming material, represented by polyvinyl alcohol and its various modifications. There are also water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins; water-dilutable coatings refer to coatings prepared by emulsifying the emulsion into a film. It is a solvent-based resin that is dissolved in an organic solvent and then emulsifier With the help of strong mechanical stirring, the resin is dispersed in water to form an emulsion, which is called post-emulsified emulsion. The pai...

Problems solved by technology

However, the current building energy-saving and thermal insulation measures are only aimed at the outer envelope of the building. Generally, no thermal insulation measures are used between the partition walls of the buildings in the building. In this way, different buildings may have different temperatures, resulting in thermal pressure. A room experiences heat loss, the flow of heat from a warmer room to a cooler room

This unfair phenomenon of heat use is likely to cause various problems and contradictions. For example, the heat loss in the household is serious, which makes the heat use uneven among neighbors, resulting in unfair phenomena, and has high building energy consumption, thus Influenced the promotion of my country's building energy conservation policy
