摘要

制备了纳米CaCO3复合丙烯酸涂料，通过对其主要性能进行检测表明，当改性纳米CaCO3的添加量为1.5%（质量）时，涂料的耐光性、耐水性、自洁性和贮存稳定性等显著改善。研究了添加轻钙、未改性纳米CaCO3、改性纳米CaCO3及其用量对丙烯酸涂料流变性的影响，结果表明，该体系的流动特性均符合Casson模型；当在丙烯酸涂料中添加1.5%改性纳米CaCO3时，其黏度对温度的敏感性下降，黏度显著降低，剪切稀化能力较强，Casson屈服应力较小，触变性增大，涂料性能改善与其流变性变化基本一致。此外，固体分改变或添加丁醇对添加改性纳米CaCO3复合丙烯酸涂料和传统丙烯酸涂料流变性的影响规律基本相同。

Abstract

Nano-CaCO3 (nanometer calcium carbonate) composite acrylic coatings were prepared

and their application performance was tested.The result indicated that when the dosage of the modified nano-CaCO3 was 1.5%(mass)

the coatings were obviously improved in such properties as light resistance

water resistance

self-cleaning and storage stability.The effects of adding light calcium carbonate

unmodified nano-CaCO3

modified nano-CaCO3 into the acrylic coatings and its dosage on the rheological property were studied.The results showed that the rheological property of this system conformed to the Casson model.When the dosage of modified nano-CaCO3 was 1.5% (mass)

the coatings showed lower viscosity sensitivity to temperature

decreased viscosity

strong shear thinning ability

low Casson yield stress

and increased thixotropy

and the performance improvement was basically consistent with the change in rheological property.In addition

changing the solid content or adding butyl alcohol had basically the same influence on the rheological property of modified nano-CaCO3 composite acrylic coatings and the traditional acrylic coatings.
