Abstract

The invention discloses a phase change microcapsule type thermal insulation emulsion. The thermal insulation emulsion comprises cellulose, polyvinyl alcohol, liquid paraffin, alkyl methacrylate, carboxyl-containing vinyl monomer, cross-linked Monomer, initiator, oxidizing agent, reducing agent, water, the contents of the above components are calculated in parts by mass: 0.1-5 parts of cellulose, 0.1-5 parts of polyvinyl alcohol, 20-50 parts of liquid paraffin, methacrylic acid 1-20 parts of alkyl ester, 1-10 parts of carboxyl-containing vinyl monomer, 0.1-10 parts of cross-linking monomer, 0.1-2 parts of initiator, 0.1-1 part of oxidizing agent, 0.1-1 part of reducing agent, water 40‑80 servings. The phase change microcapsule type thermal insulation emulsion of the present invention improves thermal insulation efficiency and has relatively high thermal insulation performance.

Description

technical field [0001] The invention relates to a thermal insulation emulsion, in particular to a phase change microcapsule type thermal insulation emulsion, its coating and its preparation method. Background technique [0002] The total energy consumption of buildings has accounted for 30-40% of the total energy consumption of the society, and it is increasing year by year with a rapid momentum, and most of them are heating and air conditioning energy consumption, so building energy saving is of great significance. At present, most of the thermal insulation coatings on the market are considered from the perspective of coatings, and the thermal insulation effect is improved by adding hollow glass beads, ceramic powder, etc., while ignoring that the emulsion can also have thermal insulation properties. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a phase-change microcapsule type thermal...
