Abstract

The invention discloses a preparation method of a phase-change energy-storage flame-retardant material. The material comprises the following components: polyethylene glycol, a thixotropic agent, glassfibers and a flame retardant. Due to the characteristics of high enthalpy of phase change, good thermal conductivity and stability, environmental friendliness and the like, the material can be widelyapplied to lithium batteries and other electrical components which are easy to heat during working, and plays a role in phase change energy storage and protection of coated materials. The phase change enthalpy can reach 120 J / g or above, and meanwhile, the flame retardant grade can reach V-1 grade or above; in addition, the material also has the characteristic of high thixotropy, so that the material has good thermal stability and extremely high shape retention capability, and can be repeatedly used for multiple times; the problem that similar products on the market cannot give considerationto high phase change enthalpy, flame retardance and shape retention capacity is solved.

Description

technical field [0001] The invention relates to a preparation method of a phase-change energy storage flame-retardant material. The preparation method of the phase change energy storage material of aspect. Background technique [0002] When a phase change energy storage material changes from a solid state to a liquid state, it undergoes a change in physical state. During these two phase transitions, the material absorbs heat from the environment and conversely releases heat to the environment. The energy that can be stored or released when the physical state changes is called the heat of phase change, and the temperature range over which the phase change occurs is narrow. During this phase transition, in which the physical state changes, the temperature of the material itself remains almost constant until the phase transition is complete. A large amount of phase change heat is transferred to the environment, resulting in a wide temperature plateau. The emergence of phase...
