Abstract

The invention discloses an energy-storing and multi-functional coating and a preparation method thereof. The energy-storing and multi-functional coating is prepared from raw materials in parts by weight as follows: 15-20 parts of a polymer emulsion, 60-90 parts of a nano-composite phase-change microcapsule suspension blended and modified with graphene oxide and nano-zinc oxide, 1-3 parts of silicon dioxide aerogel, 5-8 parts of polyvinyl alcohol, 1-5 parts of an alcoholic organic solvent, 0.1-0.2 parts of modified sodium disilicate, 0.1-0.3 parts of a wetting dispersant, 0.3-0.4 parts of an antifoaming agent and 5-10 parts of water. The coating layer of the energy-storing and multi-functional coating is stable, is prevented from cracking and peeling after long-term exposure in air and has high bonding strength, enthalpy of phase change of a product after film formation of the coating is higher, and the problem of poor temperature adjustment and control effect of the coating in the prior art is solved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an energy storage multifunctional coating and a preparation method thereof. Background technique [0002] The earth's energy is depleting day by day, and the global energy crisis is intensifying day by day, so it is particularly important to save energy and use energy effectively. At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption of the society, and it shows a trend of increasing year by year. Therefore, it is imperative to develop and apply new energy-saving building materials that can reduce building energy consumption and ensure indoor comfort. [0003] Phase change material (PCM) is a thermally functional material that can absorb or release latent heat. Unlike thermal insulation wall materials, the application of phase change materials in buildings is not limited to thermal insulation. Phase change materials can produce sever...
