【摘要】：针对现有化学融雪方法的缺陷,通过在乳化沥青中添加融雪剂,制备一种主动融雪抑冰型乳液。通过乳化沥青蒸发残留物含量和储存稳定性试验,研究融雪剂掺量和搅拌时间对乳液性能的影响;并研究不同融雪剂掺量下乳液的融雪抑冰性能。结果表明,随融雪剂掺量增大,乳液的蒸发残留物含量逐渐增大,1 d储存稳定性先变好后变差,当掺量为12%时,储存稳定性最好;随搅拌时间延长,蒸发残留物含量先增大后减小,1 d储存稳定性先变好后变差,当搅拌时间为15 min时两者都有最佳值;融雪剂掺量越大,融雪抑冰成分的释放量和释放速率越大,冷冻后试件表面结冰越少,冰层越松散,表明融雪抑冰性能越好;随时间延长,融雪抑冰成分的释放速率变慢,结冰后冰层变坚硬,表明融雪抑冰潜力变弱。
[Abstract]:Aiming at the defects of existing chemical melting method, by adding snowmelt agent in asphalt emulsion, preparation of an active anti ice snowmelt type emulsion. The asphalt emulsion evaporation residue content and storage stability test, effects of snow melting agent dosage and stirring time on the properties of the emulsion; and study the different dosage of emulsion of deicing snow anti icing performance. The results show that with the increase of content of snow melting agent, emulsion evaporation residue content gradually increased, 1 D storage stability becomes better then worse, when the content is 12%, the best storage stability; with the increase of stirring time, evaporation residue content decreased after 1 D, the storage stability becomes better after the poor, when the stirring time of 15 min both have the best value; the snow melting agent content is greater, the composition of ice snowmelt suppression release amount and release rate increases, the surface of the specimen after freezing ice less ice more loose, that snow The better the ice suppression performance is, the release rate of snow melting and ice suppression components becomes slower with time, and the ice layer becomes hard after freezing, which indicates that the potential of snow melting and ice suppression is weaker.
