摘　　要：采用聚醚多元醇、MDI-50、增塑剂、粉状填料、潜固化剂X、环保溶剂HW及其他助剂,制备了环保型单组分聚氨酯防水涂料。研究聚醚二醇/聚醚三醇配比、环保溶剂HW用量和潜固化剂X用量对防水涂料性能的影响。结果表明,其他组分不变,当聚醚二醇、聚醚三醇、环保型溶剂HW和潜固化剂X用量分别为60、40、15和6份时,制备的防水涂料物理性能和环保性能最佳。The environment-friendly one-component polyurethane(PU)waterproof coating was prepared by polyether polyols,diphenylmethane diisocyanate(MDI),plasticizer,powder filler,latent curing agent X,environment-friendly solvent HW and other additives.The effects of the ratio of polyether glycol and polyether triol,usages of the solvent HW and latent curing agent X on the performances of waterproof coating were studied.The results showed that the physical properties and environmental performances of the waterproof coating were the best when the amount of the polyether glycol,polyether triol,solvent HW and latent curing agent X was 60,40,15 and 6 parts,respectively,and other additives kept unchanging.
