叔碳酸酯改性聚酯印铁涂料的研究

Study on Versatate Modified Polyester Overprinting Coatings

采用叔碳酸酯合成高固体分的聚酯树脂 ,与甲醚化三聚氰胺甲醛树脂配制印铁涂料。研究了叔碳酸酯的用量对涂膜性能的影响 ,当叔碳酸酯的用量为 3%～ 5 %时 ,印铁涂膜具有良好的耐冲击性。

An overprinting coatings has been developed based on high solid polyester prepared with versatic acid,and methylated melamine resin.The influence of incorporation level of versatate on film performance was studied,showing that when the addition level of versatate ranges between 3%～5%,the film will have better impact strength,excellent adhesion,and chemical resistance.
