摘要
综述了AC发泡剂的制备工艺 ,重点探讨了联二脲中间体氧化制备AC发泡剂的氧化工艺 ,并指出各种氧化工艺的优缺点。此外 ,由于传统氧化工艺制备的AC发泡剂粒径粗大 ,会给微孔泡沫制品的发泡带来困难 ,介绍了AC发泡剂颗粒微细化的途径。
The preparation technique of t he AC blowing agent was reviewed. Especially, the oxidation technique of the biu rea was discussed with emphasis and the advantage and disadvantage of the oxidat ion technique was pointed out. In addition, there is some difficulty in foaming on mipor foam product owing to the AC blowing agent with large particle size, wh ich was prepared by conventional oxidation technique. The minification pathway o f the AC blowing agent was also introduced.
