摘　　要：通过乳液聚合的方法合成核壳结构乳液,并用超细无机粉体对核壳比为7/10的乳液进行改性;主要讨论高岭土,海泡石,碳酸钙,二氧化硅4种粉体对涂层玻纤布的强力和耐碱保留率的影响。结果表明:不同类型的粉体对乳液改性的效果有较大差异,当高岭土的填充量达到4‰时,耐碱保留率达87.8%。A kind of coatings is prepared by core-shell structure emulsion polymerization, which is modified with nano-ultrafine powder. Four kinds of powder such as kaolin, sepiolite, calcium carbonate, silica on the strength and alkali-resistance keeping rate of glass fabric with coatings are discussed. The resuits show that with different types of modified powder, the effect is different. The alkali-resistance keeping rate would be 87. 8% when filling amount of kaolin reach 4‰.
