生产维生素B6的固废作为固化剂在防腐涂料中的应用

Application of Solid Waste From the Production of Vitamin B6 as Curing Agent in Anticorrosion Coatings

为了将噁唑法工艺生产维生素B6中的一种难处理固废资源化,主要研究了三聚氰胺与黑膏的质量比,以及反应后产物是否分离,和反应后的产物与环氧树脂的质量比对涂膜防腐效果的影响。实验结果表明:三聚氰胺与黑膏反应分离时,其质量比为4∶1,反应产物与环氧树脂的质量比为1∶3时,涂膜的防腐效果比较好。进一步可以得到结论:利用三聚氰胺改性黑膏的产物可以用作环氧树脂固化剂使用,从而达到废物资源利用,实现绿色化学。

In order to realize the resource utilization of a refractory solid waste from the production of vatimin B6 by oxazole method, the effect of the mass ratio of melamine to black paste, the separation condition of the products, and the mass ratio of the products to the epoxy resin on the anticorrosive effect of the coating was investigated. The results showed that： when products from the reaction between melamine and black paste were separated, and the mass ratio of melamine and black paste was 4：1 and the mass ratio of reaction product to epoxy resin was 1：3, the prepared coating film had good anticorrosive effect. It＇s pointed out that melamine-modified black paste products can be used as epoxy resin curing agent, so as to achieve the resource utilization of waste.
