Abstract

The invention discloses a carbon fiber-added microcapsule shape-stabilized phase-change material and a preparation method thereof. The carbon fiber-added microcapsule shape-stabilized phase-change material comprises the following components in parts by weight: 50 to 100 parts of a core material, 200 to 500 parts of chloroform, 0.2 to 0.6 part of an emulsifying agent, 15 to 30 parts of toluene diisocynate, 6 to 15 parts of ethidene diamine and 0 to 100 parts of distilled water, wherein the core material comprises paraffin, polyethylene and carbon fiber powder, and the weight ratio of the paraffin to the polyethylene to the carbon fiber powder is (30-70):(20-50):(5-15). The microcapsule shape-stabilized phase-change material provided by the invention adopts the polyethylene and the carbon fiber as composite supporting materials, the mechanical strength of the microcapsules is greatly enhanced, the microcapsules are not broken when 10-Kg pressure is applied, and the microcapsule shape-stabilized phase-change material can be widely applied to various aspects in the field of buildings and in the fields of military, civil use, household appliances and the like. The carbon fiber-added microcapsule shape-stabilized phase-change material is wrapped by an interface polymerization method, loss of the paraffin can be retarded or stopped, heat storage and release functions of the phase-change material are guaranteed, the service life of the phase-change material is prolonged (after heat storage and release is conducted for 50 times, attenuation is zero), and the carbon fiber-added microcapsule shape-stabilized phase-change material can adapt to more use environments.

Description

Technical field [0001] The invention relates to a functional heat storage microcapsule phase change material and a preparation method thereof, in particular to a microcapsule shaped phase change material added with carbon fiber and a preparation method thereof. Background technique [0002] Phase Change Material (PCM-Phase Change Material) refers to a substance that changes the state of a substance with temperature changes and can provide latent heat. Phase change materials have the ability to change their physical state within a certain temperature range. Take the solid-liquid phase transformation for example. When heated to the melting temperature, a phase change from solid to liquid occurs. During the melting process, the phase change material absorbs and stores a large amount of latent heat; when the phase change material cools, the stored Heat must be dissipated to the environment within a certain temperature range, and the reverse phase change from liquid to solid is perfo...
