Description
Technical field
The invention belongs to technical field of road engineering materials, particularly a kind of road gap-grouting glue suitable for wet facial cleft seam and
Its preparation method.
Background technology
The pavement crack of any road all along with the whole validity period of road, and can directly affect the use longevity of road
Life and traffic safety.Pavement crack processes the destruction for easily causing pavement structure not in time.The crack repairing commonly used at present
Material mainly has pitch, modified pitch, polyurethane and epoxy resin etc..When pitch, modified pitch class crack patching material are used
Complex process is, it is necessary to slot, and require that fracture faces are dried, the top that can only be mended a split causes crack repairing not thorough, splits
Seam may may proceed to development destruction roadbed.The elongation of this kind of gap-grouting material is low simultaneously, in the presence of expanding with heat and contract with cold easily again
Secondary cracking.Conventional urethane class base joint grouting glue is met water and is easily foamed, and wet face bond effect is poor.Epoxy resin base joint grouting glue adhesive property
It is good, modest viscosity, but elongation is low, is suitable for the microcrack treatment of concrete surface.In sum, current road gap-grouting glue
Simply solve the subproblem of crack repairing, it is impossible to realize the requirement of the wet facial cleft seam high bond strength of road and elongation.
The content of the invention
In sum, it is difficult to bond the low shortcoming of wet face, elongation for existing road gap-grouting material, the present invention is provided
A kind of suitable wet environment, adhesion strength are high, elongation is high, low cost road gap-grouting glue, and the present invention uses the double-component cementation of fissures
Glue material, causes that gap-grouting material in the presence of water also can be very using amine terminated polyether, amino chain extender and prepolymer reaction
Solidify well；Acted on by interface treating agent, base joint grouting glue can well infiltrate crack and destroy the moisture film of fracture faces, while
Can be reacted with gap-grouting material and fracture faces after interface treating agent hydrolysis, base joint grouting glue is firmly bonded on crack.The cementation of fissures
The wet face bond effect of glue is good, elongation is high, viscosity is low, can be full of whole crack from Slit bottom injection, it is not necessary to slot, work
Skill is simple.
In order to achieve the above object, the technical solution adopted by the present invention is：
