摘要：

为满足秋冬季热力设备检修维护需要，研究了一种可以室温快速固化，同时具有良好隔热效果的新型隔热涂料。 在相同掺量的玻璃纤维、石英砂、珍珠岩、纤维素、减水剂、石灰的基础上，研究了不同掺量聚丙烯酸酯乳液、水玻璃和水泥对涂料固化时间的影响。 通过测试该涂料的固化时间及力学性能，得到了最佳配方。 结果表明：当水泥用量为450g，聚丙烯酸酯乳液用量为水泥用量的20%，水玻璃用量为水泥用量的13%时，涂料能够快速固化，而且具有良好的抗折和抗压强度。

Abstract: In order to meet the need of thermal power equipment maintenance in autumn and winter, a novel heat-insulation coatings system with good fast curing property at room temperatures and good heat insulation effect was prepared. Based on the same content of glass fiber, quartz sand, perlite, cellulose, water reducing agent and lime, the effect of different dosage of polyacrylate latex, water glass and cement on curing time of coatings was analyzed.An optimal formulation of coatings was obtained via the test of curing time and mechanical properties. The results showed that a coatings system comprising cement 450 g, polyacrylate latex 20wt % of the cement and water glass 13wt % of the cement gave good fast curing property and allowed the film to show good flexural and compressive strength.
