Stable rubber powder polymer composite modified asphalt and mixture
The invention discloses stable rubber powder polymer composite modified asphalt and a mixture. A preparation process comprises the following steps of: (1) reacting mercaptoalcohol with triphenyl methanol, and reacting with butylene tricarboxylic acid and furyl acrylic acid to obtain a product B; enabling active magnesium, bromooctane and o-dichlorobenzene to react; reacting with butenedioic anhydride to obtain a product D; enabling the product B, the product D and sodium p-styrenesulfonate to react; and reacting with trifluoroacetic acid and sodium hydroxide to obtain a reaction type additive. (2) co-extruding with waste rubber powder to obtain a stable rubber powder polymer; and (3) mixing with matrix asphalt to obtain the modified asphalt. Two unsaturated monomers are prepared from the raw materials and copolymerized with sodium p-styrenesulfonate to prepare a reaction type additive, the reaction type additive and waste rubber powder are co-extruded at high temperature, a three-dimensional cross-linked structure is reconstructed, and the high-temperature performance of the prepared asphalt is improved. Carboxylate and thiolate are introduced to enhance the prepared stable rubber powder polymer, so that the high-temperature performance, low-temperature performance and fatigue resistance of the prepared modified asphalt are improved.
本发明公开了一种稳定型胶粉聚合物复合改性沥青及混合料，包括以下制备工艺：(1)巯基醇与三苯基甲醇反应，与丁烯三羧酸、呋喃基丙烯酸反应得产物B；活性镁、溴辛烷、邻二氯苯反应；与丁烯二酸酐反应得产物D；产物B、产物D、苯乙烯磺酸钠反应；与三氟乙酸、氢氧化钠反应，得反应型添加剂；(2)与废胶粉共挤得稳定型胶粉聚合物；(3)与基质沥青混合得改性沥青。本发明通过上述原料制备两种不饱和单体，与苯乙烯磺酸钠共聚，制得反应型添加剂，在高温下与废胶粉共挤，重构三维交联结构，改善所制沥青的高温性能；并引入羧酸盐、硫醇盐，对所制稳定型胶粉聚合物，进行增强，改善所制改性沥青的高温性能，低温性能，抗疲劳性能。
