Abstract
The epoxy resin adhesive for use in water consists of a component I and a component II. The component I contains epoxy resin, active filler, tackifier and solvent; and the component II is mixed curing agent containing polyamide, phenolic imine and coupling agent. The epoxy resin adhesive may be used in water, and may be smeared well to the surface of cement mortar, concrete and steel material in water. It has high binding strength, high tensile strength and high shearing strength.
Description
Technical field
The present invention relates to a kind of binder formula and production technology, be mainly used in the bonding of underwater concrete and steel construction.
Background technology
Port and pier, oceans such as marine Longspan Bridge construct with the water transport hydro project in, often run into the situation of constructing under humidity and the underwater environment condition, as bonding repairing of port engineering mesotidal range district and underwater concrete structure etc.With Resins, epoxy is the matrix material of base-material, because cohesive force is strong, and good mechanical property, characteristics such as shrinkability is little have been widely used in the bonding repairing of all kinds of construction work concrete structures.But general epoxy bond material can only just can reach the adhesive effect of expection at the exsiccant bonding interface, has limited the use range of epoxy adhesive widely.
Traditional improving one's methods is with ketoimine or polyamide curing agent, adds plaster stone or unslaked lime again, and the general viscosifying power of the binding agent that so makes is low, can not satisfy high-strength requirement efficiently.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide the bonding steel construction that a kind of underwater construction uses and the binding agent of concrete structure, this binding agent is under water to sand-cement slurry, and concrete and steel surface all have good applying property.
Realize that technical scheme of the present invention is: a kind of epoxy resin adhesive for use in water, it is characterized in that being made up of component I and component I I, wherein: component I comprises Resins, epoxy, active filler, tackifier and solvent, component I I are polymeric amide, phenolic aldehyde imines and the mixing cured system of coupling agent.Calculate by weight, component I comprises: 100 parts of Resins, epoxy, 60～80 parts of active fillers, 1～5 part of tackifier, 5～15 parts of solvents; Component I I comprises: 18～30 parts of polymeric amide, 12～20 parts of phenolic aldehyde imines, 1～3 part of coupling agent; The weight proportion of component I and component I I is 4～6: 1.Component I and component I I can construct after mixing under water, solidify, and obtain excellent cohesive force with steel construction or concrete structure.
The present invention is under water to sand-cement slurry, concrete and steel surface all have good applying property, once smear just can flatten and adhere to, and molten diffusing, floating and phenomenon such as crispatura can not take place, and can stand the impact of wave, completely solidified under water, its mechanical properties of concrete mechanical performance index that bonds under water near the C50 strength grade of concrete, the intensity of bonding under water A3 steel is also higher, and its tension and slip resistance can reach 5.3M Pa and 13.6M Pa respectively.
Embodiment
The present invention is a kind of epoxy resin adhesive for use in water, form by component I and component I I, wherein: component I is the host of high-solid level content, is mainly liquid epoxies, wherein can be mixed with suitable tackifier, active filler, solvent, dispersion agent and rust-preventive agent etc. according to actual needs; Component I I is a mixed curing agent, and main component is a modified amine, is polymeric amide, phenolic aldehyde imines and coupling agent mixed system.
Resins, epoxy is low molecular weight liquid epoxy, preferably adopts the bisphenol A-type low molecular weight liquid epoxy.The active filler of used filler for reacting with water, silicate cement for example when constructing under water, helps to eliminate the influence to bonding force of residual moisture content that bonding interface exists.Tackifier structurally are a kind of aromatic compounds that hydrophilic radical is arranged, p-methyl benzenesulfonic acid sodium for example, it can replace the water molecules that is present between epoxy adhesive and the bonding interface, and binding agent is directly contacted with bonding plane, makes binding agent to having the excellent adhesivity that applies.Solvent can be adopted as dibutyl phthalate.Polymeric amide can be adopted as Versamid.Coupling agent is a silane coupling agent, it is a kind of compound that can produce certain bonding force simultaneously with polar material and apolar substance, the active group of its molecule one end and the sticking inorganics surface bonding of quilt, and the active group of the molecule the other end can combine with epoxy resin-matrix in the binding agent, so just between binding agent and adherend, play so-called " bridge formation " effect, helped improving cohesive force.
Calculate by weight, component I comprises: 100 parts of Resins, epoxy, 60～80 parts of active fillers, 1～5 part of tackifier, 5～15 parts of solvents; Component I I comprises: 18～30 parts of polymeric amide, 12～20 parts of phenolic aldehyde imines, 1～3 part of coupling agent; The weight proportion of component I and component I I is 4～6: 1, can construct under water after the mixing, solidifies, and obtains excellent cohesive force with steel construction or concrete structure.
Below in conjunction with embodiment the present invention is further described in detail, but is not limited thereto specific examples.
