Description

technical field [0001] The invention belongs to the field of material chemistry and relates to a thermal insulation material, in particular to a phase change gel thermal insulation material and a preparation method thereof. Background technique [0002] At present, the consumption of non-renewable energy is increasing on a global scale, but the replacement of renewable energy cannot be realized. Among them, building energy consumption in energy consumption is particularly huge: driven by today's rapid development of the construction industry and people's high quality of life, building energy consumption has accounted for about 1 / 3 of the world's energy consumption, and the trend of year-by-year growth is unstoppable. The reversal is mainly determined by the rapid development of my country's construction industry and urbanization in the next few decades. According to the statistics and budget of the Ministry of Construction, under the current situation, by about 2030, buildin...
