Composite modified asphalt based on epoxy resin rubber powder and mixture
The invention discloses composite modified asphalt based on epoxy resin rubber powder and a mixture, during preparation, spirocyclic phosphate is prepared from components such as 2, 4-dihydroxybenzophenone, triethylamine and chlorinated spirocyclic phosphate, a spirocyclic phosphate skeleton structure has excellent flame retardant property and ultraviolet absorption property, and the flame retardant property and ultraviolet absorption property of the spirocyclic phosphate are improved; and the o-hydroxybenzophenone skeleton structure also has excellent ultraviolet absorption performance, so that spirocyclic phosphate is introduced into the asphalt, on one hand, the flame retardant property of the asphalt can be improved, the ultraviolet aging resistance of the prepared asphalt mixture is also improved to a certain extent, and the practicability is more excellent. The process design is reasonable, the component proportion is appropriate, the prepared mixture has excellent mechanical property, temperature resistance, water resistance, solvent corrosion resistance and fatigue resistance, meanwhile, the smoke release amount is obviously reduced during construction, and the high practicability is achieved.
本发明公开了一种基于环氧树脂胶粉的复合改性沥青及混合料，在制备时，本申请先通过2,4‑二羟基二苯甲酮、三乙胺、氯化螺环磷酸酯等组分，制备得到螺环磷酸酯，螺环磷酸酯骨架结构具有较优异的阻燃性能和紫外吸收性能，而邻羟基二苯甲酮骨架结构又具有优异的紫外吸收性能，因此在沥青中引入螺环磷酸酯，一方面不仅能够提高其阻燃性能，制备得到的沥青混合料的抗紫外老化性能也得到一定提升，实用性更加优异。本发明工艺设计合理，组分配比适宜，制备得到的混合料具有优异的力学性能、耐温性能、耐水性能、耐溶剂侵蚀性能和耐疲劳性能，同时，本发明施工时烟气释放量明显降低，具有较高的实用性。
