Abstract

The invention provides phase-change energy-storage temperature-regulating slurry powder. The phase-change energy-storage temperature-regulating slurry powder is prepared from the following componentsin parts by weight: 25-35 parts of microcrystalline wax, 15-25 parts of n-decanoic acid, 12-16 parts of a flame retardant, 0.2-0.8 parts of a mildew preventive, 0.2-0.8 parts of a phase-change temperature regulator and 30-40 parts of glass beads. The phase change temperature regulator is any one or any combination of sodium chloride, potassium chloride, ammonium chloride or ammonium sulfate; and the vitrified microbeads are closed-pore vitrified microbeads with the average particle size of 0.6-0.8 mm. The prepared phase-change energy-storage temperature-regulating slurry powder is non-toxic and odorless, and after the microcrystalline wax and the n-decanoic acid are added together, the thermal cycle stability of the phase-change energy-storage temperature-regulating slurry powder is improved; and by adding the vitrified micro-beads, the heat insulation, fire prevention, sound absorption and heat preservation performances of the phase-change energy-storage temperature-regulating slurrypowder are improved.

Description

technical field [0001] The invention relates to a synthesis method of an organic compound, in particular to a phase-change energy-storage temperature-regulating slurry powder. Background technique [0002] In buildings, the heat loss of the outer envelope structure is relatively large, and the wall accounts for a large share in the outer envelope structure. Therefore, the reform of building walls and the development of wall energy-saving technology are the most important links in building energy-saving technology, and the development of external wall insulation technology and energy-saving materials is the main way to realize building energy conservation. Among them, foamed plastic insulation materials, such as EPS board, XPS board and foamed polyurethane board, are eye-catching because of their excellent comprehensive performance. [0003] However, the existing thermal insulation and energy-saving materials for external walls all have the defects of being easy to crack and...
