Unsaturated polyester concrete for pavement repair and preparation method of unsaturated polyester concrete
The invention belongs to the technical field of pavement repair, and particularly relates to unsaturated polyester concrete for pavement repair and a preparation method of the unsaturated polyester concrete. The unsaturated polyester concrete comprises the following raw materials: modified unsaturated polyester, aggregate, fibers and an anti-aging agent. Unsaturated polyester is modified through liquid nitrile rubber, the liquid nitrile rubber and the unsaturated polyester are both liquid and are good in compatibility, the liquid nitrile rubber improves the toughness of the unsaturated polyester and improves the low-temperature bending performance at the same time, and the modification process is simple, convenient and easy to implement; the modified unsaturated polyester is used as an adhesive, the bumping phenomenon caused by incoordination of rigidity of different materials is well avoided, a self-made anti-aging agent is added, the problem that resin concrete is prone to aging is solved, the wear resistance is improved, and the selected aggregate is obtained by recycling and crushing an old asphalt pavement milling material. And the thought of turning waste into wealth, savingenergy and protecting the environment can be well embodied.
本发明属于路面修复技术领域，具体涉及一种用于路面修复的不饱和聚酯混凝土及其制备方法，该不饱和聚氨酯混凝土包括以下原料：改性不饱和聚酯、骨料、纤维、抗老化剂；本发明通过液体丁腈橡胶对不饱和聚酯进行改性，由于液体丁腈橡胶和不饱和聚酯同为液体，相容性好，液体丁腈橡胶提升不饱和聚酯的韧性的同时也改善了低温弯曲性能，并且改性过程简便易行，将改性不饱和聚酯作为胶黏剂也较好地解决了不同材料之间由于刚度不协调造成的“跳车”现象，再添加自制的抗老化剂，改善树脂混凝土易老化的问题且提高了耐磨性能选用的骨料是旧沥青路面铣刨料经过回收、破碎处理而得，能很好地体现变废为宝，节能环保的思想。
