The present invention relates to the technical field of new materials, and relates to a thermal conduction enhanced organic composite shape-stabilized phase change material and a preparation method thereof. A thermal conduction enhanced organic composite shape-stabilized phase change material, which is composed of a coordination crosslinked network polymer, an organic solid-liquid phase change material and a thermal conduction enhancer, the mass percent are as follows: coordination crosslinked network polymer 1-50%, organic solid-liquid phase change material 40-98.9%, and thermal conduction enhancer 0.1-10%, the coordination crosslinked network polymer being formed by complexing of polymer compound with metal ions. The invention has simple synthesis process and convenient applications, the material having large enthalpy of phase change, excellent shape stabilizing effect, while the phenomenon of liquid leakage will not occur during operation. The material has broad application prospects in the field of thermal energy storage and management.

Thermal conduction enhanced organic composite shape-stabilized phase change material and preparation method thereof

Disclosed is a method for continuously preparing a water-soluble azo dye by coupling a nebulizer with a pipeline. According to the method, the nebulizer is coupled with a pipeline with an interception tower plate, atomized and mixed reaction liquid flow flows through the pipeline with the interception tower plate, and mixing and reacting are further enhanced through turbulent mixing on the tower plate, so that instant separation of reaction heat generated in an atomizing contact reaction from a reactant is achieved, and normal-temperature rapid continuous production of the water-soluble azo dye is achieved. Fog drops which are atomized by using the nebulizer have small particle diameter and large specific surface area, so that a diazo salt and a coupling component are sprayed separately, move face to face and can be fully contacted, and mixing and reacting speeds are increased. The preparation method is simple, and compared with preparation of a dye of the same kind with a batch reactor, in the reparation process of the water-soluble azo dye, a cold source is not required to be added additionally for cooling, thereby reducing energy consumption and improving production quality and efficiency.
