Embodiment 1

[0025] Paraffin wax with a melting point of 25° C. and a latent heat of phase change of 147 kJ / kg was selected as the organic phase change material. First dissolve 58 parts of paraffin in 280 parts of ethanol solution, heat the organic solution to 40°C, stir at constant temperature for 30 minutes, then slowly add 13 parts of nanometer γ-alumina and 10 parts of coupling agent γ-aminopropyltriethoxy Silane, stirred at high speed for 3 hours, filtered, washed and dried to prepare phase change energy storage aggregates. Then 100 parts of cement, 80 parts of phase change energy storage aggregate, 18 parts of water and 2 parts of reinforcing fiber are blended, stirred evenly, put into a mold and pressed to obtain a phase change energy storage surface layer. The latent heat value of the phase change energy storage surface layer measured by DSC is 52kJ / kg.

Abstract

The invention discloses a preparation method for a phase-change energy storage type insulating composite board. The preparation method comprises the following steps: dissolving an organic phase-change material into an organic solvent, wherein the mass ratio of the organic phase-change material to the organic solvent is 1:1 to 1:10; slowing adding a carrier gamma-aluminium oxide and a coupling agent, stirring at high speed for 2-5 h to enable the carrier to absorb the organic phase-change material fully, filtering, washing, and drying to obtain a phase-change energy storage aggregate, wherein the mass ratio of the gamma-aluminium oxide to the organic phase-change material is 1:1 to 1:6; mixing the phase-change energy storage aggregate, a basis material and water, placing the mixture into a mould, pressing to obtain a phase-change energy storage type surface layer, and adhering the phase-change energy storage type surface layer on the surface of an insulating board to obtain the phase-change energy storage type insulating composite board. The phase-change energy storage type insulating composite board provided by the invention has the advantages of capacity of phase-change energy storage and temperature adjustment, high pressure resistance, moisture protection, corrosion resistance, environmental protection, innocuity and the like.

Description

technical field [0001] The invention relates to a preparation method of a thermal insulation composite board, in particular to a preparation method of a thermal insulation composite board with phase change energy storage performance. Background technique [0002] The energy consumption per unit building area in my country is three times that of developed countries with similar climate conditions, and 95% of buildings are high-energy buildings, and building energy consumption accounts for about 30% of the total energy consumption of the whole society. my country is relatively energy-deficient, and its per capita energy consumption is only 40% of the world level, but its total energy consumption ranks second in the world. Therefore, building energy conservation is an extremely important and urgent subject for our country. [0003] At present, domestic thermal insulation composite panels are generally composed of outer panels and thermal insulation materials. The thermal insul...
