Embodiment 1
[0029] A preparation method of a comb polymer phase change energy storage material, comprising the steps of:
[0030] Add 3% of its mass of CaH to toluene 2 Carry out vacuum distillation to remove water, obtain anhydrous toluene for subsequent use;
[0031] Then the polyethylene grafted maleic anhydride and n-octadecyl alcohol of 1:2 are joined in the there-necked flask with mechanical stirring, thermometer, reflux condenser, nitrogen protection, then add catalyzer p-toluenesulfonic acid ( The consumption of p-toluenesulfonic acid is 5% of polyethylene graft maleic anhydride and n-octadecyl alcohol quality and), and toluene (the concentration of polyethylene graft maleic anhydride and n-octadecyl alcohol in toluene is 15wt%) , raised the temperature to 80°C, mechanically stirred and refluxed for 8 hours, cooled down, removed the solvent, washed, and dried to obtain a pure comb-like polymer phase-change energy storage material.
[0032] Using NETZSH DSC 200F3 differential sca...
Embodiment 2
[0038] Adjust the molar ratio of polyethylene grafted maleic anhydride to n-stearyl alcohol in Example 1 to be 1:1.5 and the rest of the conditions are the same as those in Example 1, and the properties of the prepared comb polymer phase-change energy storage material are listed in Table 1.
Embodiment 3
[0040] Adjust the molar ratio of polyethylene grafted maleic anhydride and n-octadecyl alcohol to 1:1 in Example 1, and the rest of the conditions are the same as in Example 1. The properties of the prepared comb polymer phase-change energy storage material are listed in Table 1.
