Elastic concrete for expansion joint and preparation method of elastic concrete
The invention relates to the technical field of road and bridge materials, and discloses elastic concrete for expansion joints and a preparation method thereof.The elastic concrete comprises a component A, a component B, a component C and a component D, the component A is a modified titanium dioxide/isocyanate-terminated amino polyether prepolymer compound, and the component A is prepared from isocyanate modified titanium dioxide and isocyanate-terminated amino prepolymer; the component B comprises amino-terminated polyether and an auxiliary additive; and the component C is mixed stone. The mechanical property and toughness of the elastic concrete are improved, and the material is endowed with good durability and ultraviolet resistance.
本发明涉及路桥材料技术领域，公开了一种伸缩缝的弹性混凝土及其制备方法，包括A组分：改性二氧化钛/异氰酸酯封端端氨基聚醚预聚体复合物，由异氰酸酯改性二氧化钛和异氰酸酯封端端氨基预聚体制成；B组分：端氨基聚醚和辅助增剂；C组分：混合石料。提高了弹性混凝土的力学性能和韧性，赋予材料好的耐久性和抗紫外线性能。
