Anti-freezing sand-containing fog seal material and preparation method thereof
The invention discloses an anti-freezing sand-containing fog seal material and a preparation method thereof.The anti-freezing sand-containing fog seal material has the advantages that during preparation, by adding argil and sand and matching with the mixing effect of thermoplastic particles, the anti-skid performance and deformation resistance of a pavement can be improved, and the anti-freezing sand-containing fog seal material has good toughness; the preparation method comprises the following steps: firstly, mixing calcium acetate and magnesium acetate according to a proper ratio to prepare a mixed solution, and regulating the mass fraction of an organic silicon water repellent agent to 9% under the matching of the organic silicon water repellent agent, so that the prepared anti-freezing agent has good stability, and the anti-freezing effect is good. The rheological property of the phase-change asphalt is improved under the action of taking the low-density polyethylene LDPE and the epoxidized soybean oil as the composite modifier, so that the prepared sand-containing fog seal material has good and stable anti-freezing property under the condition of taking the waterborne epoxy emulsified asphalt as a matrix, and a good guarantee is provided for long-term use of the sand-containing fog seal material.
本发明公开了一种抗凝冰含砂雾封层材料及其制备方法，本发明在制备时，通过添加陶土、砂子配合热塑性颗粒的混合作用，可以起到提高路面抗滑性能，和抗形变作用，具有良好的韧性，而在利用水性环氧乳化沥青为基体，配合选用玄武岩的砂子作用，可以提高拉拔强度，其次，通过醋酸钙和醋酸镁按照合适的配比制成混合液，且在有机硅疏水剂的配合下，通过将有机硅疏水剂的质量分数调至9％，使得制备成抗凝冰剂具有良好的稳定性，而在采用低密度聚乙烯LDPE和环氧大豆油作为复合改性剂的作用，来改善相变沥青的流变性能，在以水性环氧乳化沥青为基体的情况下，使得制备的含砂雾封层材料具有良好稳定的抗凝冰性，为其长期使用提供了良好的保障。
