【摘要】 通过预乳化工艺,解决了水性木器涂料配制过程中高效消泡剂难以分散的难题,详细研究了消泡剂预乳化过程中分散方式、分散时间、助剂配比等影响因素对于预乳化效果与消泡效果的影响。采用高压均质技术,加入适量乳化剂对消泡剂进行预乳化,得到的预乳化液方便在水性涂料体系中分散,同时保证了较好的消泡效果。更多还原

【Abstract】 A pre-emulsifilation process was used to find a solution of the difficulty of dispersing effective defoamer in production of waterborne wood coatings.The influence of dispersing approaches of defoamer,the dispersing time and composition of other additives on the pre-emulsification and defoaming effectiveness was investigated in detail.Via high pressure homogenization,the defoamer was pre-emulsified by adding appropriate amount of emulsifying agents,and the obtained pre-emulsion could be easily dispersed in the waterborne coatings with a good defoaming effect.更多还原
