Preparation method of high-strength ardealite-based road functional aggregate
The invention discloses a preparation method of a high-strength ardealite-based road functional aggregate, which is characterized in that a polyurethane solid-solid phase change material is loaded on the high-strength ardealite-based road aggregate to prepare the high-strength ardealite-based functional aggregate loaded with the polyurethane solid-solid phase change material. The phase change material comprises the following components: methylene diphenyl diisocyanate serving as a hard segment, polyethylene glycol 4000 serving as a soft segment and 1, 4-butanediol serving as a chain extender. The phase-change material has the advantages that the phase-change material spontaneously reduces the adverse effect of the temperature on the road through heat storage energy, meanwhile, the phosphogypsum-based road aggregate is used as a support to meet the requirement of the road aggregate, and resource comprehensive utilization of wet-process phosphoric acid solid waste and reduction of road temperature diseases are facilitated; the prepared phase-change material has good phase stability, no leakage phenomenon occurs in the whole phase-change heat storage process, the phase-change behavior is represented from a solid state to a solid state, and the phase-change material is widely applied to temperature regulation for roads in China.
本发明公开了一种高强度磷石膏基路用功能骨料的制备方法，将聚氨酯固‑固相变材料负载于高强度磷石膏基路用骨料制成负载聚氨酯固‑固相变材料的高强度磷石膏基功能骨料，相变材料成分包括亚甲基二苯基二异氰酸酯作为硬段，聚乙二醇4000作为软段，1,4‑丁二醇作为扩链剂。本发明的优点：相变材料通过储热能自发降低温度对道路的不利影响的同时磷石膏基路用骨料作为支撑可以满足路用骨料需求，有利于推动湿法制磷酸固废的资源化综合利用与道路温度病害的减轻；制备的相变材料有较好的相态稳定性，在整个相变储热过程中未发生泄露现象，相变行为表现为由固态至固态，广泛适用于我国路用调温。
