摘　　要：以低熔点石蜡微胶囊为相变储能材料,配以水泥、砂和外加剂制成低熔点石蜡微胶囊相变蓄热砂浆。研究了低熔点石蜡微胶囊掺量对相变蓄热砂浆施工性能、力学性能以及热工性能的影响,并进行了模拟上墙试验。结果表明,石蜡微胶囊掺量对相变蓄热砂浆的性能有着重要的影响,当其掺量在6.5%～10%时,其施工性能、力学性能和热工性能达到最佳;掺量为8%时,相变蓄热砂浆上墙无开裂,适宜于工程应用。Phase-change thermal storage insulation mortar was prepared by using low melting point paraffin as phase change material, added with appropriate cement, sand and additive. The effect of different dosage of microencapsulated paraffin on construction performance, mechanical and thermal properties of the insulation mortar were tested, and simulation experiment with insulation mortar on the wall was analyzed in this paper. The result shows： the dosage of the microeucapsulated paraffin has an important impact on the properties of the insulation mortar. When the dosage of the microencapsulated paraffin is in 6.5%-10%, the insulation mortar has the best construction performance, mechanical and thermal properties. When the dosage of the microencapsulated paraffin is 8%, the simulation wall with the insulation mortar has no crack, which is suitable for engineering application.
