Abstract

Phase change heat storage asphalt comprises the following components in parts by weight: 20-70 parts of asphalt and 20-70 parts of a phase change material, the phase change material is graphite adsorption phase change energy storage powder or aerogel adsorption phase change energy storage powder, and the specific heat capacity (J/(g.K)) of the phase change heat storage asphalt is greater than or equal to 2.5; the phase change enthalpy (J/g) is about 30-180; the phase transition temperature (DEG C) is 5-90 DEG C; according to the present invention, the phase change heat storage asphalt is usedas the electronic potting material, the phase change latent heat is released through the phase change material, the phase change heat storage asphalt adopting the formula and the preparation method has excellent heat storage temperature control performance, and the cost is far lower than the cost of a potting adhesive on the market.

Description

technical field [0001] The invention relates to the technical field of asphalt and its preparation method, in particular to phase change heat storage asphalt and its preparation method. Background technique [0002] Electronic potting glue is liquid before it is cured and has fluidity. The viscosity of the glue varies according to the material, performance, and production process of the product. Only when the potting glue is completely cured can its use value be realized. After curing, it can play the role of waterproof, moisture-proof, dust-proof, insulation, heat conduction, confidentiality, corrosion resistance, temperature resistance, and shock resistance. However, the existing electronic potting adhesives do not have the function of heat storage and temperature control, and the cost is relatively high. [0003] Phase change energy storage technology is a technology that can store energy in the form of phase change latent heat at high density. Asphalt has a wide source ...
