The results indicate that the inhibition performance of the film-forming layer depends on the composition of simulated pickling emulsion,the concentration of water-soluble 1,2-LPB and temperature of the reaction of emulsion polymerization.The film-forming mechanism of 1,2-LPB by in situ on the mild steel is also discussed in this paper. 液体聚丁二烯 乳液聚合 成膜性能 原位涂层 liquid polybutadiene emulsion polymerization performance of film-forming layer coatings by in situ TQ316.3 国家自然科学基金资助的课题 1994-06-01 2021-04-01 6
