Title:
SINGLE-COMPONENT HEAT STORAGE POTTING MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/035817
Kind Code:
A1
Abstract:
A single-component heat storage potting material. The material comprises the following components in parts by weight: 20-50 parts of a hydroxy silicone resin, 0.5-20 parts of a curing agent, 0.1-2 parts of a catalyst and 30-70 parts of a phase change material, wherein the phase change material is a graphite adsorption phase-change energy-storage powder or aerogel adsorption phase-change energy-storage powder, and the obtained single-component heat storage potting material has the following properties: a specific heat capacity (J/(g·K)) of ≥ 2.0, a phase change enthalpy (J/g) of about 30-180, that is, the heat absorption value, a phase transition temperature (℃) of 25-90℃, a specific gravity (g/cc) of 0.8-1.8, a surface drying time of 5-10 minutes, a curing time of 1-2 h, and a complete curing time of ≥ 24 h. The phase change material releases the latent heat of phase change, and the single-component heat storage potting material using the above formula has excellent heat storage and temperature control properties.
