摘要
Abstract
Bending strength was used to characterize the strength of coatings, the effects of different binders and suspending agents on the strength and suspension of EPC water-base coating were studied with single factor test method. The results show that, with the increase of the content of different binders, the flexural strength has a tendency to increase. At the same content of binder, the flexural strength of the coating taking potato modified starch as a binder significantly is greater than that taking latex powder and dextrin as binder, so the modified potato starch is used as the binder of EPC water-base coating, the content of 1.5%~2.0%. With the increase of the content of different suspending agent, the suspension has a tendency to increase. The suspension of the coatings in the same levels of Ca bentonite and Na bentonite is not very different. When the content is less than 2.5%, the effect of HCE on suspension of the coating is better than that of CMC; when the content is greater than 2.5%, the effects of HCE and CMC on suspension of the coating is without difference. Taking into account cost factors, choosing Ca bentonite and CMC as composite suspension agent, Ca bentonite of 2.5%~3.5%, CMC of 1.5% ~2.0%, the formulated coating has excellent comprehensive performance, and is able to meet the actual production needs.关键词
