摘要：在环保型喷漆的调色打样过程中，以LPG（液化石油气）为抛射剂，按一定料气比灌装，喷制样板，出现漆膜起泡的异常现象。为解决漾膜起泡间题，以LPG在环保型喷漆中的应用为切人点，通过单因素实验方法，研究料气比、漆料黏度、溶剂体系、助剂等因素对漆膜起泡的影响。结果表明：将料气比调整为1.73：1，涂料黏度调整到12.5~13.5s，增加真溶剂和慢干溶剂用量，漆膜起泡现象有所改善：在配方中添加HANSAADD1010助剂后，成功解决了漆膜起泡的问题。

Abstract:In theprocess of environmental color proofingpaint,with LPG as apropellant, according to a certain ratio of material to air jet plate after filling, appear an abnormal phenom enon of film bubbling.To solve film foaming problem, with LPG application in environmenta protection paint as starting point. Through single factor experiment method, study the ratio of material to gas, paint material viscosity, solvent system, promoter and other factors on the paint blistering. The result show that the film foaming phenomenon was improved, while the ratio of material to gas was adjusted to 1. 73 :1, the viscosity of paint was adjusted to 12. 5~ 13.5 s, the amount of true solvent and slow dry solvent was increased. after adding HANSA ADD 1010 auxiliary in the formula, the success of the film bubble is solved.

抛射剂是指能将气雾剂容器中的内容物喷射出
来的物质。抛射剂可分为氢氟烃、氢氯氟烃、氯氟烃、
烃类化合物、醛类化合物和压缩气体6大类。喷漆中常用抛射剂为烃类化合物（如LPC）、醛类化合物
