Embodiment Construction

[0026] In the following, the embodiments of the present invention will be described in detail.

[0027] Step 1: Prepare raw materials. Raw material of the present invention comprises:

[0028] 1. The hydrogen bond donor is one or more of amide compounds, carboxylic acid compounds, and polyols. For example, oxalic acid, ethylene glycol, and the like.

[0029] metal salts. The metal salt can be selected from a wide range, for example, it can be selected from hydrated metal salts or anhydrous metal salts. The cation of the metal salt is selected from: H + , Li + 、Na + 、K + , Mg 2+ , Ca 3+ 、Sr 2+ 、Ba 2+ 、Cr 2+ , Fe 2+ 、Co 2+ 、Ni 2+ 、Cu 2+ , Zn 2+ 、Cd 2+ 、Al 3+ , Ga 3+ , Sn 2+ 、In 3+ , Pb2+ One or more in; the anion of the metal salt is selected from NO 3 - , SO 4 2- , Cl - 、Br - , F - , I - 、PO 4 3- , BF 4 - 、PF 6 - one or more of. For example, the composition includes copper chloride, zinc nitrate tetrahydrate, lithium nitrate, disodium hydrog...

Abstract

The invention provides an inorganic icon liquid-based phase-change energy storage material. The inorganic icon liquid-based phase-change energy storage material is prepared from the following components of any one of an H-bond donor and metal salt and any one of quaternary ammonium salt and quaternary phosphonium salt, wherein the H-bond donor is prepared from one or multiple of an amide compound, carboxylic acid and polyhydric alcohol; the mass percentage of the metal salt in the total mass of the inorganic icon liquid-based phase-change energy storage material is not lower than 5 percent. The invention also provides a preparation method of the inorganic icon liquid-based phase-change energy storage material. The inorganic icon liquid-based phase-change energy storage material provided by the invention has a higher heat conductivity coefficient and a higher phase-change enthalpy, is low in cost and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of material synthesis, in particular to the application of phase change energy storage materials. Background technique [0002] Phase-change energy storage materials can store temporarily unused energy and release it when needed, which can alleviate the contradiction between energy supply and demand and save energy. Utilizing this characteristic of phase change energy storage materials, it can be used in the fields of air conditioning energy saving, solar energy, aerospace, and electric power. Since the performance of a single phase change material is unstable during use, it cannot meet the requirements of practical applications. The improvement of phase change materials and the research on composite phase change energy storage materials have become the focus of research in recent years. [0003] According to the way of energy storage, energy storage materials can be roughly divided into three categories: s...
