Abstract

The invention belongs to the field of research and development of novel materials, and particularly relates to a standard energy storage material as well as preparation and application thereof. The standard energy storage material is prepared from the following components in parts by weight: 10-50 parts of sodium sulfite, 5-20 parts of a hardening agent, 40-70 parts of crystal wax, 10-25 parts ofwater, 1-4 parts of a curing agent, 0.5-1.0 part of dibenzoyl peroxide and 0.5-1.0 part of dibutyltin diacetate. The standard energy storage material has the advantages of being suitable for phase change temperature, relatively large in heat conductivity coefficient and high in energy storage density.

Description

technical field [0001] The invention belongs to the field of research and development of new materials, and in particular relates to a standard energy storage material and a preparation method thereof. Background technique [0002] Standard energy storage materials use the latent heat capacity of substances in the phase transition process to store or release energy. The theoretical basis of energy storage materials has been established for a long time. Advanced foreign countries began to study them as early as the 1960s, while my country only started the research on standard energy storage materials in the 1980s. There are many kinds of standard energy storage materials, which can be divided into solid-solid, solid-liquid, liquid-gas, and solid-gas standard energy storage materials according to their phase transition modes. According to the material composition, it is divided into inorganic standard energy storage materials, organic standard energy storage materials, and co...
