Super-tough anti-cracking modified asphalt for ultrathin overlay and preparation method and application of super-tough anti-cracking modified asphalt
The invention provides super-tough anti-cracking modified asphalt for an ultrathin overlay and a preparation method and application of the super-tough anti-cracking modified asphalt. The modified asphalt is prepared from the following raw materials in parts by weight: 100 parts of petroleum asphalt, 5 to 10 parts of elastomer binding agent, 5 to 10 parts of internal stress absorbent, 0.1 to 0.3 part of antioxidant, 0.01 to 0.05 part of nano ZnO, 1 to 5 parts of interfacial agent and 0.001 to 0.005 part of vulcanizing agent. Asphalt is compounded and modified through an elastomer binding agent and an internal stress absorbent, a few asphalt molecules are bound through a vulcanization structure of symmetrical linear molecules, the high-temperature performance of the asphalt is improved, and liquid nitrile rubber is dissolved in the bound asphalt molecules by utilizing the excellent low-temperature performance and flowing state of the liquid nitrile rubber; and finally, a boundary-sea-island double-network structure is formed, the peripheral network structure provides certain high and low temperature performance, and the inner network structure mainly improves the low-temperature toughness of the material and enhances the crack resistance of the asphalt.
本发明提供了一种超薄罩面用超韧抗裂型改性沥青及其制备方法和应用，该改性沥青包括以下重量份数的原料：石油沥青100份、弹性体束缚剂5‑10份、内应力吸收剂5‑10份、抗氧化剂0.1‑0.3份、纳米ZnO0.01‑0.05份、界面活性剂1‑5份、硫化剂0.001‑0.005份。通过弹性体束缚剂和内应力吸收剂复合改性沥青，通过对称线性分子的硫化结构束缚少许沥青分子，提高沥青的高温性能，利用液体丁腈橡胶优异的低温性能和流动态，使其溶于被束缚住的沥青分子中，从而起到提高沥青低温抗裂性的作用，最终形成边界‑海‑岛的双网络结构，外围网络结构提供一定的高低温性能，内网络结构主要提升材料低温韧性，增强沥青的抗裂性能。
