Abstract

The invention belongs to the technical field of highway crack repair materials and preparation methods thereof, and mainly solves the technical problems that the existing materials used for repairing pavement cracks easily cause pavement crack protrusion, the material strength is low, the elongation at break is low, the permeability is low, the environment is polluted, the curing time is long and the pavement binding property is poor. The material is formed by a component A and a component B through curing. The component A comprises 30 to 65 parts of polyoxypropylene diol N220, 40 to 25 parts of polyoxypropylene diol N210, 12 to 5 parts of amino-terminated polyoxypropylene ether D2000, 8 to 2 parts of carbon black, 7 to 2 parts of titanium dioxide and 3 to 1 parts of catalyst; the component B comprises 171.4 parts of polyether polyurethane prepolymer and 28.6 parts of di 2-ethyl hexyl phthalate and the like; after the component A and the component B are mixed according to a mass ratio of 1:1, the immobilization time of mixture is shorter than or equal to 8min under 25DEG C, the curing time is shorter or equal to 90min and the road can be opened to traffic after curing.

Description

technical field [0001] The invention belongs to the technical field of road crack repairing materials and preparation methods thereof, and in particular relates to a composite material for repairing road cracks and a preparation method thereof. Background technique [0002] Cracks are one of the most common and most prone early diseases of pavement. Although the cracks in the initial pavement have no obvious impact on the performance of the highway pavement, as the cracks extend and expand, the pavement will age rapidly and be seriously damaged. At the same time, if the cracks on the highway pavement are not treated in time, the rainwater will infiltrate along the cracks and accumulate under the pavement floor. In severe cases, it will lead to traffic accidents, resulting in personal and property losses. [0003] At present, the seam filling materials used for repairing pavement mainly include: hot asphalt, asphalt emulsion, special materials, etc. Among them, hot asphalt...
