C_5和C_9石油树脂改性制备吸音矿棉板防水剂的研究

Preparation of the Waterproofing Agent for the Mineral Wool Board from Modified C_5 and C_9 Petroleum Resin

研究了改性制备C5、C9混合石油树脂乳液的方法,主要讨论了C5、C9混合的最佳质量配比,改性剂马来酸酐及分散剂马来松香的用量,改性时间和碱液用量对乳液性能的影响。实验结果表明,最佳制备工艺条件为:C5石油树脂与C9石油树脂混合质量比为1∶3;改性时间为3h;改性温度为200℃;马来酸酐质量分数为1.5%;马来松香质量分数为9%;碱液为NaOH溶液,质量分数为2%。混合石油树脂乳液与石蜡乳液混合质量比为1∶2,制备出了吸音矿棉板防水剂。

The mixed petroleum resin emulsion prepared from the C5 and C9 petroleum resin were modified with maleic anhydride.The effects of the mixing ratio between the C5 and C9 petroleum resin,amount of maleic rosin and maleic anhydride, modification time and the alkali liquor on properties of the emulsion were discussed.The results showed that the optimum process conditions were：C5 petroleum resin/C9 petroleum resin mixing ratio of 1∶3,maleic anhydride mass fraction of 1.5%, maleic rosin mass fraction of 9%,NaOH mass fraction of 2%,petroleum resin modification temperature of 200 ℃,petroleum resin modification time of 3 h,and modified petroleum resin emulsion/wax emulsion mixing ratio of 1∶2.
