Preparation method of anti-freezing emulsified asphalt cement mortar material
The invention relates to a preparation method of an anti-freezing emulsified asphalt cement mortar material, and belongs to the technical field of building materials. In the technical scheme of the invention, a prepared composite elastomer material is subjected to filling modification, elastomer particles are in contact with asphalt to generate a swelling effect, and light oil in Jianqing can be absorbed firstly, so that the contents of saturated components and aromatic components are reduced, and the contents of colloid and Manqing are relatively increased; contest tendency on the componentsis formed in modified Jianqing, at last, a new balanced system is formed; the elastomer material is added firstly to effectively improve the plasticity of Jianqing and transmit the excellent performance to the matrix Jianqing so as to enhance the low-temperature deformation resistance of the modification system, meanwhile, according to the technical scheme, the modified calcium sulfate whiskers are added into the material, effective dispersion entanglement is formed in the material, the dispersion performance of the material is further improved, and meanwhile the mechanical property and toughness strength of the material are effectively improved through the formed three-position network structure.
本发明涉及一种抗冻型乳化沥青水泥砂浆材料的制备方法，属于建筑材料技术领域。在本发明技术方案中，通过制备的复合弹性体材料进行填充改性，弹性体颗粒与沥青接触后发生溶胀作用，首先能吸收渐青中的轻质油分，使得饱和分和芳香分含量降低，胶质和满青质含量相对上升，在改性渐青中将形成争夺这部分组分的倾向，最终形成一种新的平衡体系，首先弹性体材料的添加，有效提升渐青的塑性同时将其优越的性能传递到基质渐青，使得改性体系低温抗变形能力增强，同时本发明技术方案在材料内部添加了改性的硫酸钙晶须，在材料内部形成有效的分散缠结，进一步改善材料的分散行性能，同时，其形成的三位网络结构，有效提高材料的力学性能和韧性强度。
