Embodiment 1

[0030] Mix 0.4 parts by weight of paraffin, 0.2 parts by weight of butyl palmitate and 0.4 parts by weight of sodium acetate trihydrate for use; add 1 part by weight of expanded porous perlite to a vacuum reaction kettle, evacuate the air in the kettle, and then slowly add the compound After stirring for 3-5 minutes, slowly pressurize the kettle to normal pressure to infiltrate the mixture into the expanded porous perlite until the mixture is completely infiltrated into the expanded perlite phase-change material component; After mixing and stirring 1 part by weight of the thermal insulation component and 0.2 part by weight of the polymer macromolecule, the thermal insulation and energy-saving material is obtained.

Embodiment 2

[0032] Mix 0.3 parts by weight of paraffin wax, 0.3 parts by weight of butyl palmitate and 0.4 parts by weight of sodium acetate trihydrate for use; add 1 part by weight of expanded porous perlite to the vacuum reaction kettle, evacuate the air in the kettle, and then slowly add the compound After stirring for 3-5 minutes, slowly pressurize the kettle to normal pressure to infiltrate the mixture into the expanded porous perlite until the mixture is completely infiltrated into the expanded perlite phase-change material component; After mixing and stirring 1 part by weight of the thermal insulation component and 0.2 part by weight of the polymer macromolecule, the thermal insulation and energy-saving material is obtained.

Embodiment 3

[0034] Mix 0.4 parts by weight of paraffin wax, 0.3 parts by weight of butyl palmitate and 0.3 parts by weight of sodium acetate trihydrate for use; add 1 part by weight of expanded porous perlite to a vacuum reaction kettle, evacuate the air in the kettle, and then slowly add the compound After stirring for 3-5 minutes, slowly pressurize the kettle to normal pressure to make the mixture infiltrate into the expanded porous perlite, and the mixture is completely infiltrated into the expanded perlite phase change material component to complete; mix the obtained substance with 2 parts by weight of the coagulation material After mixing and stirring with 1 weight part of the thermal insulation component and 0.2 weight part of the polymer macromolecule, the thermal insulation and energy-saving material can be obtained.

Abstract

The invention discloses a self-regulating temperature phase change energy storage material and a preparation method thereof. The phase change material includes: inorganic phase change material, organic phase change material and expanded perlite, cementitious material, anti-cracking material or slow setting viscosity increasing material. The preparation method of the self-regulating phase change energy storage material of the present invention comprises the steps of: 1) mixing paraffin, butyl palmitate and sodium acetate trihydrate for use; 2) adding expanded porous perlite in a vacuum reactor, Evacuate the air in the kettle, then slowly add the mixture in 1) and stir, slowly pressurize the kettle to make the mixture in 1) penetrate into the expanded porous perlite, and wait until the mixture in 1) completely penetrates into the expanded perlite phase change material component to complete; 3) Mix and stir the substance obtained in 2) with the coagulation material, thermal insulation components, and polymer polymers to obtain a thermal insulation and energy-saving material. The phase-change energy-saving material of the present invention uses a mixture of organic phase-change materials and inorganic material intersecting materials as phase-change components. The product has high heat storage, good chemical stability, and low heat transfer rate. Features such as limitations in the scope of use.

Description

technical field [0001] The invention relates to a phase change material, in particular to a self-regulating temperature phase change energy storage material and a preparation method thereof. The phase change material is widely used and can be applied to industrial and civil buildings, public buildings, etc. in non-severely cold areas External thermal insulation of exterior walls (paint or ceramic tile decoration), internal thermal insulation of external walls, indoor temperature adjustment, household partition walls, suspended ceilings, stairwells, roofs, ceilings and other parts that require thermal insulation and heat insulation. Background technique [0002] Phase change materials refer to substances that change their phase state and absorb or release heat as the temperature changes. Phase change energy storage material technology is an emerging research hotspot in the field of materials in recent years. It is currently in the stage of applied research. This technology ha...
