Elastic adhesive, combined product for road seal, anti-skid road seal structure and preparation method and application of anti-skid road seal structure
The invention belongs to the technical field of road maintenance, and particularly relates to an elastic adhesive, a combined product for a road seal, an anti-skid road seal structure as well as a preparation method and application of the anti-skid road seal structure. The elastic adhesive is prepared from the following raw materials in percentage by mass: 45 to 55 percent of petroleum asphalt, 30 to 40 percent of water, 0.9 to 1.2 percent of acid, 0.8 to 1.2 percent of emulsifier, 0.4 to 1 percent of stabilizing aid, 3 to 5 percent of viscoelastic aid, 2 to 3 percent of compatilizer, 0.5 to 0.8 percent of anti-aging agent, 5 to 6 percent of polyurethane block copolymer emulsion and 0.2 to 0.3 percent of sulfide silane coupling agent. The elastic adhesive provided by the invention is high-performance emulsified asphalt which is fast in demulsification, excellent in adhesive performance and resistant to aging, the viscoelastic auxiliary agent is combined with the polyurethane block copolymer emulsion for composite modification, and the elastic adhesive has higher adhesive strength and elastic recovery capability, and can strongly connect anti-skid particles and improve the comprehensive performance of a sand seal layer.
本发明属于道路养护技术领域，具体涉及一种弹性粘合剂、用于道路封层的组合产品、抗滑道路封层结构及其制备方法和应用。所述弹性粘合剂的原料以质量百分含量计，包括石油沥青45～55％、水30～40％、酸0.9～1.2％、乳化剂0.8～1.2％、稳定助剂0.4～1％、粘弹助剂3～5％、相容剂2～3％、抗老化剂0.5～0.8％、聚氨基甲酸酯嵌段共聚物乳液5～6％和硫化物硅烷偶联剂0.2～0.3％。本发明提供的弹性粘合剂是一种破乳快、粘结性能优、耐老化的高性能乳化沥青，其中采用粘弹助剂结合聚氨基甲酸酯嵌段共聚物乳液复合改性，具有更高的粘结强度与弹性恢复能力，能够强力连接抗滑颗粒，提高砂类封层的综合性能。
