摘　　要：采用纳米CaCO3粉体对涂层用聚丙烯酸酯乳液胶粘剂进行改性,制得应用于玻纤布涂层的纳米CaCO3/聚丙烯酸酯乳液复合胶粘剂。对加入不同配比CaCO3粉体改性后的胶粘剂进行了粒径测试,并测试分析所制得乳液胶粘剂的固含量、粘度、稳定性的影响。然后对玻纤布进行涂层,测试涂层的耐碱性、粘结力。结果显示:当粉体加入量为2‰左右时,所得乳液胶粘剂的固含量、粘度、稳定性及涂层性能最优,玻纤布表面涂层的耐碱性及粘结力最好,显出最佳的综合性能。Nano-CaCO3 is used for the modification of polyacrylate emulsion adhesive which is used as the coating of glass fiber mesh. The particle size distribution, viscosity, soild content and stability of the resultant emulsion are studied. Then the adhesive property, alkali-resistance performance and mechanical properties of the coating under the influence of nano-CaCOa are measured. It is found that when the load- ing of nano-CaCO3 20%, the viscosity, soild content, stability, alkali-resistance performance and bond strength of the coated glass fiber meshes are the best, the synthesis performance is best.
