Abstract

The invention discloses anti-impact composite kerb and a preparation method thereof. The kerb comprises a decorative surface layer and a base layer, wherein the decorative surface layer is prepared from the following raw materials in parts by weight: 80-100 parts of waste plastics, 20-30 parts of pulverized fuel ash, 10-20 parts of silicon dioxide, 5-15 parts of SBS modified asphalt, 3-8 parts of stabilizer, 1-5 parts of a coupling agent and 1-3 parts of antioxidant; and the base layer is prepared from the following raw materials in parts by weight: 50-60 parts of silicate cement, 20-30 parts of quartz sands and 6-12 parts of construction glue powder. The preparation method of kerb comprises the steps of preparing the decorative surface layer, preparing materials of the base layer and combining the decorative surface layer with the base layer. According to the composite kerb and the preparation method, the composite kerb has good corrosion resistance, good temperature resistance, strong tensile strength, strong impact resistance and simple preparation process, and can be easily molded.

Description

technical field [0001] The invention relates to the technical field of road construction materials, in particular to an impact-resistant composite curb stone and a preparation method thereof. Background technique [0002] Curb stones generally refer to the boundary stones used on the edge of the road surface, also known as curb stones or edge stones, which are used to distinguish roadways, sidewalks, green spaces, isolation belts and other parts of the road on the road surface, so as to ensure the traffic safety of pedestrians and vehicles. And to ensure that the edge of the road is neat. The roadside stone is made of uniform natural stone by mechanical cutting. The strength of the stone must be qualified. It is required to have uniform color, no cracks on the surface, complete edges and corners, consistent appearance, no obvious spots, color difference, and weathering is not allowed. It is not allowed to drop, smash, bump or touch at any time, so as not to cause damage. ...
