摘　　要：采用环氧大豆油调整产品体系黏度,以潜固化剂固化方式制备了无溶剂单组分聚氨酯防水涂料。讨论了环氧大豆油和醛亚胺类潜固化剂的用量对产品的黏度、VOC含量以及涂膜力学性能的影响。结果表明,环氧大豆油用量在25~30份、潜固化剂的用量在1.5~2.0份时,所制备的无溶剂环保型单组分潜固化聚氨酯防水涂料能满足PU防水涂料GB/T 19250—2013的要求。In the development of solvent-free and environmental-friendly one component latent curing poly-urethane waterproof coatings,epoxy soybean oil instead of organic solvent was used in these formulas to adjust the viscosity,and a self-made latent curing agent was added.The influences of the amount of epoxy soybean oil,latent curing agent and other chemical additives on the viscosity,volatile organic compounds(VOC)content,physical and mechanical properties of polyurethane waterproof coating were studied.The results showed that,when the dosage of epoxy soybean oil was 25~30 parts and the dosage of latent curing agent was 1.5~2.0 parts,the solvent-free and environmentally friendly one-component latent curing polyurethane waterproofing coating had optimal comprehensive performance which could meet the requirements of PU waterproofing coating GB/T 19250-2013.
