Description
Technical field
The two component polyurethane repair sheets and preparation method thereof that the present invention relates to a kind of for road surface belong to adhesive neck
Domain.
Background technique
Crack is that road surface is most common, one of most incident early disease.Although the crack that initial stage generates is to highway pavement
Service performance have no significant effect, if but not in time to highway pavement occur crack handle, rainwater is along fracture void
It penetrates into and accumulates under road deck, under traffic load repeated action, rainwater and the roadbed effect of accumulation generate purt mud phenomenon, into
And make pavement distress, and it is serious to lead to the broken of slab, there is pit slot, road surface is made structural damage occur, reduces
The service life on road surface.It is therefore desirable to carry out timely cementation of fissures maintenance process to highway pavement.
Traditional patching material is all with modified pitch for main substrate, since pitch is heat-sensitive material, summer intensity meeting
Decline, can feel like jelly bellding or is passed rupture；Become fragile when low temperature, the power of expanding with heat and contract with cold of destruction and pitch itself is rolled by vehicle
Influence originally repairing road surface rupture again quickly；In addition, the water resistance and resistance to ag(e)ing of pitch are poor, it is also easy to produce water damage
Bad, durability is not easy to guarantee.
Polyurethane repair glue has many advantages, such as that curing time is adjustable, viscosity is low, caking property is strong, solves previous road surface and opens
The problem of digging, long-time close traffic, cost is saved, has been to safeguard the method for road surface economically and efficiently.
Publication number CN103214823A discloses a kind of polyurethane grouting material and preparation method thereof, first in reaction kettle
Chain extender, MDI is added through temperature reaction after polyether polyol, dioctyl phthalate dehydration cooling is added, cooling is added and helps
It is made after agent nitrogen charging.Packaging can be directly opened to use, it is more convenient and efficient than previous grouting material.
Publication number CN102516492A disclose it is a kind of for road maintenance maintenance two-component polyurethane grouting material and
Polyether polyol is added in the reaction kettle with condenser, blender first in preparation method, crosslinking agent is uniformly mixed and is added
Heat heating after adding water, foam stabiliser, catalyst held for some time, cools down up to component A, at normal temperature with more benzene
Quito methylene polyisocyanates is uniformly mixed.Institute can be solidified by adjusting the additional amount control of catalyst as gap-grouting material
The time needed.
Publication number CN101649040A discloses a kind of oil soluble polyurethane grouting material of high flash point antiflaming type, feature
Be using TDI or MDI etc. be raw material, react to form performed polymer with polyether compound, and use higher boiling double solvents and phosphoric acid
Species compound is efficient flame-retarding agent, and has finally obtained the polyurethane material of rigid foam induration, induration compression strength
Up to 10MPa.
Summary of the invention
The technical problems to be solved by the invention are proposing a kind of double groups for road surface with for the above-mentioned prior art
Divide polyurethane repair glue, with excellent water repellence, even if construct still has excellent performance in a humidity environment,
It is secondary its with excellent weather-proof high and low temperature resistance, even if under rugged environment still have excellent bonding force and elongation.
