摘要/Abstract

摘要： 以家具厂含漆废水为原料，通过自行配制的絮凝剂回收漆渣并制备一种再生硝基木器漆。探索了漆渣收集条件，对再生硝基木器漆配方进行优选，并对再生硝基木器漆的性能进行检测。结果表明：漆渣絮凝剂中A、B组分体积比为1：1，投放pH值为8~9时具有最佳絮凝效果；在再生漆配制过程中加入成膜物质松香改性醇酸树脂及溶剂新戊二醇，所得再生漆光泽度达到85，硬度达到0.8，都符合木器涂料性能标准；再生硝基木器漆在300 ℃内失重率比硝基木器漆高5.6%，自腐蚀电位与硝基木器漆基本一致，具有良好的耐热抗蚀性能。

Abstract: A regenerated nitrocellulose lacquer was obtained from the spray paint waste water of furniture factory by collection and regeneration of lacquer slag. The optimum flocculation effect of lacquer slag was obtained as the dosage of A and B in the flocculants was 1:1 and the pH value was 8-9. And the performance of lacquer could reach the performance standard when rosin modified alkyd resin and dimethyltrimethylene glycol were added in the progress to make up regenerated lacquer. The weight loss rate of regenerated nitrocellulose lacquer was 5.6% higher than that of the nitrocellulose lacquer and they showed similar free corrosion potential. The regenerated nitrocellulose lacquer showed perfect corrosion and oxidation resistance.

Key words: wood coating, lacquer slag, collection, regeneration, nitrocellulose lacquer
