A nano thermal insulation coating

Abstract

The invention discloses a nano insulating coating which is prepared from the following raw materials in parts by weight: 100 parts of an organosiloxane modified acrylic emulsion, 5-12 parts of a silicon dioxide aerogel, 1-2.6 parts of ceramic fibers, 1-2.5 parts of a carbon nano tube, 0.2-1 part of calcium silicate, 2-5 parts of nano zirconium oxide, 3-7 parts of nano zinc oxide, 5-9 parts of calcium carbonate whiskers, 15-20 parts of sepiolite, 5-20 parts of expanded perlite, 8-15 parts of nano titanium dioxide, 0.8-2.0 parts of a segmented copolymer, 1.5-3.8 parts of dodecanol ester, 0.2-5.0 parts of benzotriazole, 2-3.5 parts of a defoaming agent, 0.5-2 parts of glycerol, 0-1.5 parts of a thickener, 3-10 parts of a coupling agent and 30-60 parts of water. The nano insulating coating disclosed by the invention is good in insulation, high-temperature resistant, high in strength and pollution resistant and is strong in adhesive force and long in service life of building wall spaces and base bodies.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano heat-insulating coating. Background technique [0002] In recent years, with the rapid development of world science and technology and social production, people are increasingly aware that environmental and energy issues have become urgent problems to be solved in the 21st century, and energy issues play an important role in the economic development of countries around the world. At present, the national government not only needs to improve the energy-saving design standards of buildings under construction and to be built in the future, but also carry out energy-saving improvements on the original buildings that have already been built. Therefore, the topic of energy saving and heat insulation has become an important topic in today's social science circles.

Problems solved by technology

[0003] The method of painting thermal insulation coatings on building walls to ensure that buildings have energy-saving performance has been more and more widely used. The existing building thermal insulation coatings mainly use ordinary Portland cement and fly ash. , fiber and other materials are used as heat insulation fillers, the heat insulation, heat resistance and adhesion to the wall of the coating cannot meet the requirements of the society and need to be improved and improved
