Description
Technical field:
The present invention relates to a kind of epoxyn and preparation method thereof, particularly a kind of can use under water epoxy adhesive and preparation method thereof.
Background technology:
Along with The development in society and economy, water conservancy project construction project field requires bonding various material of construction in water, and reservoir dam is carried out requiring in water, to stick with glue the bonding various patching materials of agent when repair in the crack.In other field, the demand of under water surrounding, using tackiness agent is arranged also like boats and ships, medical treatment, breed etc. equally.But seldom and there are shortcomings such as serviceability is relatively poor, bonding strength is not high, poor water resistance in employable under water at present epoxyn.
Summary of the invention:
The objective of the invention is to overcome the defective of prior art; To serviceability is not good in the present tackiness agent water, bonding strength is low; Not water-proof characteristics, provide a kind of can fast setting in water, the brushing performance is good, bonding strength is high, the epoxy adhesive of water-tolerant and preparation method thereof.
In order to realize the foregoing invention purpose, underwater epoxy tackiness agent of the present invention is made up of A, two kinds of components of B, and the A component is to have added the epoxy resin base fluid of various filler specials, auxiliary agent; The B component is that its weight percent consists of: 15-23% epoxy resin E-51,15-23% epoxy resin E-44,6-8% epoxy active diluent by two kinds of special curing agents and curing catalyst is composite forms under water; 2-5% toughner 304 resins, 13-20% talcum powder, 6-9% active calcium oxide, 1.5-2.0% organobentonite; The 2-4% white titanium pigment, 0.5-1.0% coupling agent, 0.3-1.0% dispersion agent, 0.3-1.0% skimmer; 1085 solidifying agent 10-15%, 810 solidifying agent 5-10%, 1.5-2.2% curing catalyst; Wherein, 1085 solidifying agent, 810 solidifying agent and curing catalyst are B component composition, and surplus is that the A component is formed.
Adopt bisphenol A type epoxy resin E-51 and epoxy resin E-44 to be used among the present invention.The molecular structure of bisphenol A type epoxy resin has determined that its cured article has very high intensity and bonding strength, and higher erosion resistance is arranged.Select bisphenol A type epoxy resin (like E-44, E-51) to be used, the epoxy resin E-44 viscosity is big, but its bonding force is big, and epoxy resin E-51 viscosity will hang down, so be used with epoxy resin E-44, can replenish mutual deficiency.
The epoxy active diluent that adopts among the present invention is an ethylene glycol diglycidylether, and this thinner is less to epoxy curing systems thermal distorsion temperature influence, and the bicyclic oxygen reactive thinner that paint film flexibility and shock resistance are had clear improvement and act on.It not only can reduce the viscosity of epoxy adhesive system, improves the coating and the flowability of glue, improves its wetting capacity and wetting capacity, and has improved the shock resistance of paint film, counter-bending ability and resistance toheat.
The toughner that adopts among the present invention is 304 unsaturated polyesters of resin processing plant of Xinhua.This toughner can be miscible with epoxy resin, participates in curing reaction, improves the fragility of epoxy resin cured product, plays toughening effect.
The filler that adopts among the present invention is the mixture of active calcium oxide, talcum powder and organobentonite, Rutile type Titanium Dioxide.In tackiness agent, suitably add talcum powder and organobentonite as the part filler, can reduce the consumption of resin relatively, reduce cost.Simultaneously also can improve physical and mechanical properties,, reduce linear expansivity as increasing modulus of elasticity; Reduce cure shrinkage, increase thermal conductivity, increase toughness; Increase dielectric properties (electric breakdown strength), increase the ability of sclerosis back glued membrane absorbed oscillation, increase use temperature; Increase bonding strength, and improve water-fast, medium-resistance.In addition, have a layer moisture film under water between tackiness agent and the adherend, so select partly to absorb water filler; Active calcium oxide (unslaked lime) commonly used; It and the surperficial water reaction of adherend generate oxyhydroxide, have improved interface conditions, and the reaction heat of emitting has simultaneously promoted the curing reaction of tackiness agent.
Adopt special-purpose underwater curing agent 1085 and 810 composite uses among the present invention, when general underwater curing agent is used under water, compare with in dry environment, using, cohesive strength reduces by more than 50 at least, and appearance " whiting " phenomenon.1085 fully under water the strong epoxy curing agent be a kind of hydrophobic class solidifying agent, it and water do not react, and get rid of outside the adherend water with the epoxy resin reaction when gluing and bond.It can not only be in wet environment and bonding under water, and its cohesive strength is compared conservation rate and is close to a hundred per cent with under dry environment, using.But because of its amine value is low, consumption is big, so high 810 underwater curing agent and the curing catalyst DMP-30 of complex amine value uses, regulates its consumption, improves curing speed.
The coupling agent that the present invention adopts is γ-glycidyl propyl trimethoxy silicane (KH-560).
The dispersion agent that the present invention adopts is the modest 923S of moral, and it has special interfacial activity, can help pigment wetting and decondensation, and it can be adsorbed on surface of pigments and prevent to return slightly, makes coating have the good preservation stability, and is bentonitic good acvator.
The skimmer that the present invention adopts is that moral is modest 6800, belongs to HV, solvent-free system dedicated defoamer.
The preparation method of underwater epoxy adhesive of the present invention operates according to following steps: (each material consumption all is weight percentage)
The first step, the preparation of A component:
The skimmer moral modest 6800 of the modest 923S of dispersion agent moral of the coupling agent KH-560 of the epoxy resin E-44 of the epoxy resin E-51 of 15-23%, 15-23%, epoxy active diluent ethylene glycol diglycidylether 6-8%, 0.5-1.0%, 0.3-1.0%, toughner 304 unsaturated polyester 2-5%, 0.3-1.0% is poured in the dispersed with stirring still successively; Stir; Pour organobentonite 1.5-2.0% into; Stir again, after stirring, add talcum powder 13-20%, active calcium oxide 6-9%, white titanium pigment 2-4%; High-speed stirring is disperseed, and grinds then, packs;
Second step, the preparation of B component:
The curing catalyst DMP-30 of 1085 solidifying agent 10-15%, 810 solidifying agent 5-10% and 1.5-2.2% is stirred in encloses container;
The 3rd step, before using A, B component are mixed, stir, promptly make underwater epoxy adhesive.
Underwater epoxy adhesive preparation method of the present invention is simple, and technology is strict, and product brushing performance is good, and curing speed is fast, and bonding strength is high, and water-fast, acid-alkali-corrosive-resisting is free from environmental pollution.Can be widely used in various material of construction of bonding and mending concrete crack in water.
