金属表面脱漆剂的研究

摘要：金属防护和装饰过程中不可避免的使用涂料，但如果涂层遭到破坏，就需要把旧漆膜除掉以重新进行涂装。脱漆剂的配方对脱漆的效果和对基体的影响不可忽视，合适的脱漆剂对某个基材的处理非常重要。本文主要研究了脱漆剂的多种配方，通过改变脱漆剂配方的种类，配方的含量，以及控制脱漆环境下温度来研究配方对基体表面漆膜的脱漆效果。结果表明：在以二氯乙烷为主溶剂的脱漆配方中加入18ml正己醇，15ml正丁酸和5ml液体石蜡会对硝基漆有较好的脱漆效果；在此基础上将正己醇改为正丁醇得到新的脱漆配方：100ml二氯乙烷，15ml正丁醇和5ml液体石蜡，此配方有更好的脱漆效果；为了减少有机溶剂的使用，可采用20ml20%浓度的氢氧化钠，10ml二乙二醇丁醚和70ml蒸馏水的配方，该水性配方对铁片表面的硝基漆有最佳的脱漆效果。47046

The study of metal surface paint remover

Abstract: Metal protective and decorative coatings used during the inevitable, but if the coating is damaged, you will need to remove the old paint to re-paint. Strippers stripping formula and the effect on the substrate to be reckoned with, a suitable paint remover for processing a substrate is very important. This paper studies a variety of formulations paint remover, paint remover by changing the kind of recipe, recipe content, as well as under the control of ambient temperature and stirred for paint stripping and other factors to the study of the substrate surface paint stripping effect. The results show that: N-hexyl alcohol was added 18ml dichloroethane main solvent stripping formulations, 15ml n-butyric acid and 5ml of liquid paraffin will have better stripping effect lacquer ; On this basis will hexanol instead of n-butanol to give the new paint stripping formulations: 100ml dichloroethane, 15ml of n-butanol and 5ml liquid paraffin, this formulation has a better effect of stripping; To reduce the use of organic solvents, can be 20ml20% sodium hydroxide, 10ml and 70ml distilled water, diethylene glycol butyl ether formulations, the aqueous formulation of lacquer surface iron has the best stripping results.
