Abstract

The invention discloses an energy-storage temperature-regulating microcapsule phase-change thermal insulation material for clothing and a preparation method of the material. The thermal insulation material comprises a core material and a wall material, wherein the core material is a mixture which is mixed by organic alcohol and organic ester in a molar ratio of (6-7) to (3-4); the wall material is a mixture which is mixed by chitosan and silicon dioxide gel in a molar ratio of 1 to 1; a dosage proportion of the wall material to the core material is 1 to 3; the wall material is 1 mu m-2 mu m thick; average particle diameter of the microcapsule thermal insulation material is 5 mu m-6 mu m. The preparation method comprises the following steps: (1), preparing the core material; (2), preparing a wall material prepolymer; (3), preparing a microcapsule phase-change thermal insulation material; and (4), separating and purifying. The preparation method disclosed by the invention is simple and convenient to operate; the prepared microcapsule phase-change thermal insulation material is moderate in phase-change temperature, great in enthalpy of phase change, and has the advantages of good regulation and thermal insulation effect, long thermal insulation time, no influences on clothing wearing comfort, and the like, and has a better using effect.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to an energy storage temperature-regulating microcapsule phase-change thermal insulation material for clothing and a preparation method thereof. Background technique [0002] Phase Change Material (PCM - Phase Change Material) refers to a substance that changes shape with temperature and can provide latent heat. The process of a phase change material changing from solid to liquid or from liquid to solid is called a phase change process. At this time, the phase change material will absorb or release a large amount of latent heat to keep the temperature of the material constant. Since the energy latent heat of the phase change material is very large, the temperature can be maintained for a long time to achieve the purpose of heat preservation. [0003] Most of the traditional clothing insulation materials use fiber fabrics as insulation materials, and achieve a certain ins...
