(2) adopt the decompression absorbing process that the complete adsorption and permeation of emulsion that step (1) obtains is entered pearlstone, promptly obtained phase change material composite expanded perlite particle;
(3) wilkinite with 0.5～10 weight part mixes in the particle of step (2) preparation, and uniform mixing had both got wilkinite and coated expanded pearlite batholith phase-changing energy storage material.
Described organic phase change material is a paraffin, perhaps lipid acid, perhaps organic alcohol, the perhaps mixture of the organic alcohol of organic acid.
The particle diameter of described expanded perlite granule is 150～2000 μ m.
The particle diameter of described bentonite clay particle≤44 μ m.
Compared with prior art, the present invention has following advantage:
1, makes full use of the strong characteristics of pearlstone internal void adsorptive power, realized high organic phase change material infiltration capacity;
2, adopt ultra-fine wilkinite that the opening micropore of phase change material carrier pearlstone is carried out end-blocking, liquid matrix is intercepted by wilkinite and adsorbs under the high temperature, can effectively prevent the leakage that phase change material may cause when the thing phase transformation, thereby solve the leakage problem of phase change material in the porous medium;
