摘要
通过自由基乳液聚合,合成具有核壳结构的苯丙乳液,以此乳液作为酚醛树脂泡沫材料的界面剂,考察了此种界面剂对酚醛树脂泡沫材料应用性能的影响。试验结果表明,用合成的苯丙乳液界面剂处理酚醛泡沫材料,可以有效地解决酚醛泡沫材料强度低、吸水率大、酸性强等方面的缺点,使得酚醛泡沫材料在建筑外墙保温系统中得到更广泛的应用。
Styrene-acrylic emulsions with core-shell structure had been prepared by the polymerization of free-base emulsion, and applied as interface agent on phenolic foam panel The effects of this kind of interface agent on phenolic foam panel for ex- ternal thermal insulation system were investigated. The results show that phenolic foam strength,water absorption（by mass） and pH value were improved by this emulsion interface agent,and made phenolic foams have a wide range of applications on external ther- mal insulation system.
