稀释剂对转炉尘灰制备高固体分防腐涂料特性的影响

Influence of Diluents on the Performances of High Solid Anti-corrosion Coating Prepared by Converter Dust

为了研究利用转炉尘灰制备高固体分防腐涂料工艺中稀释剂的影响,选取平均粒度为59.33μm的转炉尘灰制备高固体分防腐涂料,以苯甲醇作为稀释剂研究不同稀释剂用量对高固体分防腐涂料性能的影响。随着稀释剂含量的增加,转炉尘灰制备的高固体分防腐涂料的黏度随之减小,涂膜表面的气泡含量减少,涂膜的耐盐水腐蚀能力下降,而耐酸腐蚀能力增强,稀释剂用量为15%时涂膜耐酸腐蚀能力较强。

In order to study the effects of diluent on the performances of the coatings prepared by converter dust, high solid anti-corrosion coatings were prepared by the converter dust with an average particle size of 59.33 μm. Using benzyl alcohol as the diluent, its effect of addition amount on the properties of the high solid anti-corrosion coatings was investigated. With increase of the diluent content, the viscosity of high solid anti-corrosion coatings reduces coupled with the decrease in surface bubble content of the coating film, and the corrosion resistance to salt water for the coating film decreases but its acid corrosion resistance increases. When the dosage of diluent is 15% ,the coating film is more resistant to acid corrosion.
