高分子包膜材料对抗凝冰剂缓释性能的影响
|
摘要
抗凝冰剂是一种代替沥青混合料中不同粒径的矿料、使沥青路面具有主动除冰雪功能的一种外加剂。国内同类产品缓释性能差,普遍缺乏长效性。为增强抗凝冰剂的缓释效果,研究借鉴农药、化肥包膜技术,分别用聚苯乙烯、环氧树脂、水溶性酚醛树脂对大粒盐进行包膜,并对包膜方法、稀释比例、大粒盐粒径及固化温度等条件进行探究,得出如下结论,采用环氧树脂包膜,4.75～9.5 mm粒径大粒盐,环氧树脂与环己酮稀释比例为4∶1,加入环氧树脂质量30%的固化剂且在100℃下固化,溶液不掺加改性蓄盐载体,粒子表面裹一层改性蓄盐载体,以此条件下制备的抗凝冰剂缓释效果较好。
Anti-freezing additive is a kind of admixture which has the function of removing snow and ice in the asphalt pavement instead of the mineral aggregate with different particle size in the asphalt mixture. Domestic similar products fall short of slow release performance, and generally lack of long-term effect. In order to enhance the sustained release effect of anticoagulant ice cream, in this experiment, the technology of pesticide and chemical fertilizer coating were used. The conditions of coating method, dilution ratio, particle size of large salt and curing temperature were studied, and the following conclusions were drawn: large grain salt with particle size of 4.75-9.5 mm, the dilution ratio between epoxy resin and cyclohexanone of 4∶1, epoxy resin of 30% as curing agent, and curing at 100 ℃. The solution was not add modified salt storage carrier but particle surface was coated with a layer of modified storage carrier. The anticoagulant ice agent prepared under these conditions had a good sustained release effect.
