Abstract
Selecting bauxite refractory aggregate and chromium slag as composite refractory aggregate,phenolic resin and silica sol as composite binder,and sodium bentonite and powdered sodium carboxymethyl cellulose (CMC) as composite suspension agent,the best ratio in EPC water-based paint was determined through the orthogonal test and production validation,that is sodium bentonite content 5％,CMC 0.5％,resin 2％,silica sol content 5％.The results show that,the coating has good processing performance,the problems of paint in the process of using sand,porosity and other issues were solved,which can better meet the needs of practical production,and the cost is low.关键词
