Composite phase change microcapsule and preparation method thereof
The invention relates to a composite phase change microcapsule and a preparation method thereof, the composite phase change microcapsule comprises a capsule core and a capsule wall, the capsule core comprises paraffin and a clay material, the capsule wall is formed by polymerization of styrene and a second compound, and the second compound is methacrylic acid and/or methyl methacrylate. The paraffin-clay composite phase change material prepared by the method disclosed by the invention is relatively large in phase change latent heat, high in thermal stability and high in mechanical strength. The phase change microcapsule has a heat-resistant and anti-leakage microcapsule shell with enough strength, and the size of the capsule core and the thickness of the capsule shell are controllable.
本发明涉及一种复合相变微胶囊及其制备方法，复合相变微胶囊复合相变微胶囊包括囊芯和囊壁，所述囊芯包括石蜡和粘土材料，所述囊壁由苯乙烯和第二化合物经聚合形成，所述第二化合物为甲基丙烯酸和/或甲基丙烯酸甲酯。本发明方法制备的石蜡‑粘土复合相变材料相变潜热相对大、热稳定性高、机械强度大。本发明相变微胶囊有足够强度的耐热、防渗漏的微胶囊外壳，囊芯大小及囊壳厚度可控。
