Abstract： |
The invention discloses a making method of silica clad phase-change energy-reserving material microcapsule, which comprises the following steps: emulsifying organic phase-change material; cladding; blending 10% organic phase-change material and 0.5-5% emulsion; adding in the 75-200% solution with 0.2-3wt% non-ionic surface activator stabilizer; stirring under 40-95 deg. c for 10-60min with 0-2. 5% alkaline metal salt; dispersing phase change material evenly to form emulsion liquid; adding 7. 5-75% silicic acid carbethoxy and 0.15-5% acid in the emulsion liquid; reacting in the water bath under 20-70 deg. c for 3-12h; aging under indoor temperature; filtering; washing to obtain the product. |
