Abstract

The invention relates to the technical field of energy storage materials, in particular to a 89 DEG C phase change material (PCM) and a preparation method and application thereof. The material is prepared from the following components of, in parts by weight, 100 parts of magnesium nitrate hexahydrate, 0.5-5 parts of graphite, 0.5-10 parts of thickeners, 0.1-2 parts of corrosion inhibitors, 0.1-2 parts of surface active agents and 0.1-1 part of a coloring agent. The89 DEG C phase change material can solve the problems that a material is prone to be condensed on the surface of a thermal conductive pipe, the corrosion performance is high, the thermal conductivity is poor, and the material is prone to leak to cause dangers. The phase change temperature of the material is matched with the working temperature of a heat supply net, and the material can be applied to phase change energy storage heat exchangers in a combined heat and power generation system.

Description

technical field [0001] The present invention relates to the technical field of energy storage materials, and more specifically, relates to an 89-degree phase change energy storage material and its preparation method and application. Background technique [0002] Energy is the foundation of human survival and development, among which electric energy and thermal energy are one of the forms of energy widely used by human society. At present, the combined heat and power system can output both electric energy and thermal energy to the outside world, which can simultaneously meet the demand for electricity and heat in urban and rural life and production. However, since the heat and electricity peaks are often staggered, when the heat output of the combined heat and power system is greater than the real-time heat demand, energy storage is required to reduce energy waste. The development of energy storage technology is inseparable from the development of efficient energy storage ma...
