Abstract

The invention discloses an intelligent temperature self-regulating material and a preparation method thereof. The intelligent temperature self-regulating material comprises stearate and glass pumice,wherein stearate is loaded in the pores of the glass pumice; and the stearate is composed of methyl stearate and ethyl stearate in a mass ratio of 1: 1. The phase-change energy-storage composite heat-preserving material provided by the invention has large phase-change latent heat and stable morphology in the process of phase change; and after the heat-preserving material provided by the inventionis attached onto a building exterior wall, temperature can be effectively controlled and regulated; the phase-change energy-storage composite material generates phase-change circulation in a collection cycle; in a room adopting the phase-change material provided by the invention, the maximum daytime temperature of the room is 3 to 5 DEG C (a difference of 5 DEG C between a room temperature and themaximum temperature) lower than the maximum daytime temperature of an ordinary room, and the nighttime minimum temperature of the room is about 1 DEG C higher than the nighttime minimum temperature of the ordinary room; thus, the intelligent temperature self-regulating material provided by the invention has good application prospect.

Description

technical field [0001] The present invention relates to an intelligent self-temperature-regulating material and its preparation method and use method, in particular to an external wall insulation material with a phase-change energy storage function, which can intelligently adjust the temperature, and can keep the temperature of the living environment at a suitable temperature for the human body and The preparation method and application method thereof belong to the field of energy-saving new materials. Background technique [0002] Building energy consumption has always accounted for a large proportion of energy consumption. In some developed countries, 40% of the total energy consumption of the whole society is used for building energy consumption, while in my country, about 28% of the total social energy consumption is used for building energy consumption. The heat loss caused by the wall during the heat transfer process is the main factor affecting whether the wall is ins...
