Embodiment 1
[0028] Take 100g of rutile titanium dioxide (using R-996) and put it into a beaker, add 500ml of ethanol, stir for 5-10 minutes to dissolve the rutile titanium dioxide in ethanol, then add 3-aminopropyltriethoxysilane into the beaker (Using KH550) 8.5g, stirred evenly, placed in a condensing reflux device, and condensed and refluxed at 60°C for 3 hours to obtain a mixture, which was filtered, washed, and dried under normal conditions to obtain 3-aminopropyl tris Ethoxysilane modified rutile titanium dioxide.
[0029] Weigh 200g of paraffin-type phase-change microcapsules (model RUBITHERM RT27) into a beaker, add 800ml of ethanol, mix well, add 80g of 3-aminopropyltriethoxysilane modified rutile-type titanium dioxide into the beaker, and Place in a condensing reflux device, adjust the temperature of the water bath to 80°C, and carry out condensing and reflux operation for 4 hours. After reflux, filter and wash to obtain high-reflective phase-change microcapsules.

Embodiment 2
[0033] Take 120g of rutile titanium dioxide (using NTR-606) and put it into a beaker, add 500ml of ethanol, stir for 5-10 minutes to dissolve the rutile titanium dioxide in ethanol, then add tridecafluorooctyltriethoxysilane into the beaker (Using the modifier of ACTYGLON-G617 model) 11g, after stirring evenly, place it in the condensing reflux device, carry out the condensing reflux operation at 70°C for 4 hours to obtain a mixture, which is filtered, washed and dried under normal conditions Tridecafluorooctyltriethoxysilane modified rutile titanium dioxide was obtained.
[0034] Weigh 180g of acrylic wall-type phase-change microcapsules (model ESM-44) into a beaker, add 800ml of ethanol, mix well, and add 110g of tridecafluorooctyltriethoxysilane modified rutile titanium dioxide into the beaker , adjusting the temperature of the water bath to 70° C., performing condensation and reflux operation for 5 hours, and obtaining high-reflective phase-change microcapsules by filterin...
Embodiment 3
[0038] Take 100g of rutile titanium dioxide (using R-258) and put it into a beaker, add 500ml of ethanol, stir for 5-10 minutes, dissolve the rutile titanium dioxide in ethanol, and then add γ-(methacryloyloxy) propane to the beaker 7.5g of trimethoxysilane (using KH570), stirred evenly, and condensed and refluxed at 70°C for 6 hours to obtain a mixture. The mixture was filtered, washed and dried under normal conditions to obtain γ-(methacryloyloxy ) Propyltrimethoxysilane modified rutile titanium dioxide.
[0039] Weigh 160g of acrylic wall-type phase-change microcapsules (model ESM-44) into a beaker, add 800ml of ethanol, mix well, add γ-(methacryloyloxy)propyltrimethoxysilane to the beaker to modify 85g of non-volatile rutile titanium dioxide, adjust the temperature of the water bath to 75°C, carry out the condensation and reflux operation for 6 hours, after reflux, filter and wash to obtain high-reflective phase-change microcapsules.
