Phase change heat storage granule with modified resin as shell material and preparation process of phase change heat storage granule

Abstract

The invention relates to phase change heat storage granules with a modified resin as a shell material and a preparation process of the phase change heat storage granules. The phase change heat storagegranules comprise a shell material and a core material, wherein the core material is arranged inside the shell material; the shell material consists of a light sensitive prepolymer, an active diluent, a light sensitive agent and a heat conduction material; the mass percentages of the components are as follows: 70-80% of the light sensitive prepolymer, 10-20% of the active diluent, 1-10% of the light sensitive agent, and 1-3% of the heat conduction material; the core material is saturated fatty acid of 10-14C. As the modified resin is adopted as the shell material of the phase change heat storage granules, the core material wrapped by the shell material is not leaked off in the heat absorption / release process, meanwhile, due to adoption of a granular phase change heat storage material, theheat exchange area is greatly increased, and due to adoption of the modified resin as the shell material, the overall heat conduction property is improved, so that the heat response time of a phase change material is shortened, and the heat storage capability of the phase change material is utilized to the maximum extent.

Description

Technical field [0001] The invention relates to the technical field of building energy-saving materials, in particular to a phase-change heat storage particle using a modified resin as a shell material and a preparation process thereof. Background technique [0002] Among all kinds of energy consumption, building energy consumption accounts for a large part, so energy-saving materials have a lot of room for development in the future. The usual phase-change heat storage building materials simply mix phase-change materials and building materials in proportion without packaging, which causes leakage problems during the heat-absorbing and melting process of phase-change materials. At present, most building materials are low-transmission materials for energy conservation. The thermal performance material makes the phase change material's thermal response time too long after being blended with the phase change material, it has no heat storage capacity, and loses its meaning of existenc...

Problems solved by technology

The usual phase change heat storage building materials simply mix phase change materials and building materials in proportion without encapsulation, which causes leakage problems easily during the process of heat absorption and melting of phase change materials. Thermal performance materials, so that after mixing phase change materials, the thermal response time of phase change materials is too long, it is not enough for heat storage capacity, and loses its meaning of existence
