C5石油树脂制备防水涂料

C5石油树脂制备防水涂料
摘  要
实验针对C5石油树脂颜色深、热稳定性差和与其它高分子聚合物相容性不好等缺点，采用加氢改性和化学改性两种方法对C5石油树脂进行改性，并以改性后的石油树脂为原料，研制防水涂料。实验以镍基加氢催化剂对石油树脂进行加氢改性，在固定床微型加氢反应装置上进行催化加氢反应，考察了催化剂制备条件对石油树脂性质的影响，确定最佳加氢工艺。实验以马来酸酐为改性剂对石油树脂进行化学改性，考察了马来酸酐的用量、引发剂用量、反应时间以及反应温度等因素对石油树脂性质的影响，确定了最佳改性工艺条件。实验通过乳化剂的筛选、乳化温度和乳化时间的考察，确定了乳化工艺的最佳条件，从而制备出三种石油树脂乳液，然后加入增强剂，增稠剂，消泡剂，pH调节剂，溶剂等助剂，制备出三种防水涂料产品，并对涂料的性能进行了测定。结果表明，以氢化C5石油树脂作为涂料的成膜物质制备出的产品，各方面性能都优于另外两种，因此实验最终以氢化C5石油树脂作为成膜物质，得到了一个最佳的防水涂料配方，此配方制备出的环保型防水涂料，可以较好的应用在内墙涂料和家居装饰等领域中。

Abstract
  C5 petroleum resin test for depth of color, poor thermal stability and compatibility with other, modified and chemically modified by hydrogenation of two methods modified C5 petroleum resin, and to the modified petroleum resin as raw material, waterproof coating. Hydrogenation experiments with nickel catalysts for hydrogenation of petroleum resin modified, in the fixed bed hydrogenation reactor on micro-hydrogenation reaction, catalyst preparation conditions on the properties of petroleum resin, to determine the optimum. Experiments with maleic anhydride modifier resin chemical modification of oil, investigated the amount of maleic anhydride, the amount of initiator, reaction time and reaction temperature on the properties of petroleum resin, to determine the optimal modification conditions. Screening test by emulsifier, emulsifying temperature and emulsification time of inspection, the emulsifying process to determine the best conditions, thus prepared three kinds of petroleum resin emulsion, then join the enhancer, thickener, defoamer, PH regulators, solvents and other additives, waterproofing coatings prepared three kinds of products, and the performance of coatings was determined. The results showed that hydrogenated C5 petroleum resin coating film-forming material as prepared products, all aspects of performance are better than the other two, Therefore, the ultimate test to hydrogenated C5 petroleum resin as a film-forming substances, has been one of the best waterproof coating formulations. This recipe produced a green waterproof coating, can be better used in interior wall paints and home decoration field.
Key words: C5 petroleum resin;  Hydrogenation modification; Chemical modification; Waterproof coat
