Abstract
The invention discloses an interface binding agent used between polyurethane or polyurea elastomer and hydraulic engineering concrete substrate, and is characterized by comprising the components: epoxide resin, butyl glycidyl ether, polysulfide rubber, 2, 4, 6 N, N-dimethyl aminomethyl phenol and r-aminopropyl triethoxy silane. By utilizing the polyurethane and the polyurea elastomer which are wear resistant and have excellent impact resistance, the interface binding agent can be successfully applied to hydraulic engineering water release buildings.
Description
Technical field
The invention belongs to binding agent matrix material and preparation method thereof, especially a kind of interface adhesive that is used between urethane or polyurea elastomer and concrete for hydraulic structure ground.
Background technology
At present, be that urethane or polyurea elastomer directly are coated in the base material concrete surface in the construction process, but its cohesive strength is very low, can not bear the impact of high velocity flow, and the binding agent of the reactionless type of prior art solves this problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reactive interfacial binding agent and preparation method thereof that is used between urethane or polyurea elastomer and concrete for hydraulic structure ground, use this interface adhesive can make the tool excellent anti be applied to hydraulic structure sluicing flow-passing surface, reduce maintenance cost towards attrition resistant urethane or polyurea elastomer.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: a kind of interface adhesive that is used between urethane or polyurea elastomer and concrete for hydraulic structure ground, its composition contain Resins, epoxy, butylglycidyl ether, thiorubber,
R-aminopropyl triethoxysilane and organic amine curing agent.The quality proportioning of its each component is:
132 parts of Resins, epoxy
Butylglycidyl ether 10-100 part
Thiorubber 10-80 part
R-aminopropyl triethoxysilane 1-15 part
Organic amine curing agent 20-132 part.
The preparation method who is used for the interface adhesive between urethane or polyurea elastomer and concrete for hydraulic structure ground of the present invention is:
A, butylglycidyl ether, r-aminopropyl triethoxysilane are added in the Resins, epoxy successively, and stir respectively successively, be formulated as the A component;
B, general
Thiorubber adds in the organic amine curing agent successively, and stirs respectively successively, is formulated as the B component;
When c, application, A component and B component mix and get final product.
Described organic amine curing agent can be diethylenetriamine or polymeric amide.
The invention has the beneficial effects as follows: by the present invention can with the tool excellent anti towards attrition resistant urethane, polyurea elastomer can success be applied to hydraulic structure sluicing flow-passing surface, reduce maintenance cost.Urethane, polyurea elastomer directly are applied to concrete binding intensity less than 1MPa; coating is easily washed away by current; can reach more than the 3MPa by interface adhesive urethane of the present invention, polyurea elastomer and concrete cohesive strength; coating is difficult for being dashed by current, has satisfied high velocity flow flow-passing surface protection requirement.
