Problems solved by technology

Chinese patent application 102127395A prepares a microcapsule phase change material, which solves the technical problems of low paraffin incorporation, poor energy storage performance, and easy leakage, but the preparation process is complicated.
Chinese patent application 102531506A obtains a composite phase change material by stirring and mixing a porous matrix and a paraffin phase change material. This method overcomes the shortcomings of the capsule encapsulation method such as complicated process and high cost.
Chinese patent application 103694963A discloses a paraffin composite phase change material prepared by using graphitized carbon microspheres as a carrier. The carrier has a high thermal conductivity, but the preparation method is complicated and cumbersome and needs further improvement
Chinese patent application 102212339A provides a ternary composite preparation method of expanded graphite / montmorillonite / paraffin nano-shaped phase change material. The obtained material has high thermal conductivity and stable phase change, but the phase change value is also relatively low, the highest up to 159J / g,

Abstract

The invention discloses a preparation method of a paraffin-SEBS thermoplastic elastomer composite phase change material. The paraffin-SEBS thermoplastic elastomer composite phase change material comprises the following components in parts by weight: 30-80 parts of phase change paraffin and 20-70 parts of SEBS elastic plastic. The flexible composite phase-change material has the beneficial effectsthat the blank of the current flexible composite phase-change material in the market is solved, the adsorption capacity is high, and the phase-change enthalpy value is large. Besides, the phase-changematerial with controllable phase-change temperature can be obtained by adjusting the mass ratio of the phase-change materials with different marks, so that the application field of the paraffin-basedcomposite phase-change material is further widened, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of energy-saving energy storage materials, in particular to a preparation method of a paraffin-SEBS thermoplastic elastomer composite phase change material. Background technique [0002] With the continuous development of the world economy, industrial energy consumption continues to increase, and the energy crisis and environmental pollution caused by the consumption of traditional fossil energy have prompted people to improve the utilization efficiency of fossil energy and develop new energy, such as wind energy, solar energy, and geothermal energy. Wait for new energy. Heat storage technology is an effective means to realize efficient utilization of resources, and at the same time plays an important role in shifting peaks and filling valleys in new energy sources such as solar energy and power development. [0003] The core of heat storage technology is energy storage materials. Phase change materials use the phase...
