2) with 1 part of emulsifiers dissolve in 100~400 parts of water, form the aqueous solution; After oil solution and aqueous solution, after the high shear field effect, pulverize, make miniemulsion;
3) miniemulsion is moved in the reactor, add the aqueous solution of water soluble starter, initiated polymerization after polymerization is finished, slowly cools to discharging after the room temperature.
The preparation method of another kind of organic phase transition material capsule water miscible liquid, it is characterized in that: the step of method is:
1) miscellany, the oil-soluble initiator with 10~50 parts phase change materials, 10~200 parts of one or more vinyl monomers or two (many) vinyl monomers mixes, and forms oil solution; 1 part of emulsifiers dissolve in 100~400 parts of water, is formed the aqueous solution;
2) with after oil solution and the aqueous solution, after the high shear field effect, pulverize, make miniemulsion;
3) miniemulsion is moved in the reactor, the rising reactor temperature carries out polymerization, after polymerization is finished, slowly cools to discharging after the room temperature.
