Phase-change nano-biochar composite material for asphalt pavement temperature control and preparation method of phase-change nano-biochar composite material
The invention discloses a phase-change nano biochar composite material for asphalt pavement temperature control and a preparation method, and belongs to the technical field of asphalt pavement raw material production, and the phase-change nano biochar composite material comprises the following raw materials by mass: 30-50 parts of 150-250 mesh biochar, 4-6 parts of a high adsorption activity cracking agent, 1-3 parts of a coupling agent, 1-3 parts of a coupling agent, and 1-3 parts of a coupling agent. The phase-change modifier is prepared from the following components in parts by weight: 5-10 parts of a porous modified activator, 4-6 parts of a hydrochloric acid solution, 20-30 parts of a polyethylene glycol organic phase-change modifier, 15-25 parts of a sodium alginate modified nano polymerizing agent, 2-4 parts of a high-strength gelatinized matrix and 1-3 parts of a high-efficiency organic dissolving agent. The polyethylene glycol organic phase-change modifier is more reliably sealed and stored to effectively prevent leakage, so that a better and longer-term phase-change temperature regulation function is realized, and when being used as one of asphalt pavement raw materials, the polyethylene glycol organic phase-change modifier absorbs a large amount of heat at high temperature and releases a large amount of heat at low temperature, so that the purpose of automatically controlling the temperature of an asphalt pavement is achieved; and adverse effects of extreme weather conditions are reduced.
本发明公开了一种用于沥青路面温控的相变纳米生物炭复合材料及制备方法，属于沥青路面原料的生产技术领域，相变纳米生物炭复合材料的制备原料包括以下质量份的各原料：150‑250目的生物炭30‑50份，高吸附活性裂解剂4‑6份，多孔隙改性活化剂5‑10份，盐酸溶液4‑6份，聚乙二醇有机相变改性剂20‑30份，海藻酸钠改性纳米聚合剂15‑25份，高强凝胶化基质2‑4份，高效有机溶解剂1‑3份。本发明对聚乙二醇有机相变改性剂进行更加可靠的封存以有效防止其泄漏，从而实现更好、更长期限的相变调温功能，应用时作为沥青路面原料之一，高温时吸收大量热量，低温时释放大量热量，达到沥青路面的自动温控目的，减轻极端气候条件的不利影响。
