The curing agent for sticking glue, a plasticizer and a formula thereof break through the traditional patterns and have the characteristics of high bonding strength and fast curing.
Description
The present invention relates to a kind of tackiness agent, specifically be based on the tackiness agent of Resins, epoxy.
Existing is that base material doses that other solidifying agent, coupling agent etc. are auxilliary to be added tackiness agent that agent constitutes and have multiplely with Resins, epoxy, but when being used for bonded metal, defectives such as the low and tackiness agent of bonding fastness time of coagulation is long then generally being arranged, thereby influenced construction quality and progress.Crack, perforation etc. in use appear in many equipment, support, oil tank etc., and welding is inapplicable, is a kind of very easy, economic and feasible maintaining method with sticking benefit of tackiness agent then.
Purpose of the present invention just provides a kind of new tackiness agent, makes it have the characteristic that cohesive force is strong, setting time is short.
The present invention is achieved in that adhesive is to include Resins, epoxy, solidifying agent and coupling agent, Resins, epoxy is selected E-44 and E-51 Resins, epoxy for use, solidifying agent is selected T31 epoxy hardener, polyamide 6 50# and benzoic sulfimide for use, adds a kind of homemade amine-phenolic condensation compound solidifying agent.T
31Epoxy hardener is auxiliary reagent factory, Kunshan, a Jiangsu product.Coupling agent is selected r-(2,3 epoxies, third amino) propyl trimethoxy silicane for use.The proportioning raw materials of this adhesive (weight percent) is:
E-44 Resins, epoxy 29-32%, E-51 Resins, epoxy 5-9%, liquid polysulphide rubber 3-5%, r-(2,3 epoxies, third amino) propyl trimethoxy silicane 1-2%, tributyl phosphate 1-3%, dinoctyl phthalate 1-3%, amine-phenolic condensation compound 4-6%, T
31Epoxy hardener 2-4%, Versamid 650#2-3%, benzoic sulfimide 1-2%, 2,4,6-three (dimethylamino methyl) phenol 1-3%, activated magnesia 2-4%, reduced iron powder 34-38%.Wherein except that homemade solidifying agent, other raw materials are the commercially available prod.The preparation of amine-phenolic condensation compound is to be 1: 1 with phenol, hexanediamine and industrial formol three mol ratio: 0.5-1 gets material, earlier phenol and hexanediamine are mixed stirring, and by warming-in-water, temperature is controlled at 60-75 ℃, drips industrial formol, is warmed up to 95-105 ℃ after adding, stirred 3-4 hour, cool to 85-95 ℃ again, and then be warming up to 105-110 ℃, and under 60 mmhg decompression dehydration 2 hours.
Generally this adhesive is first and second liang of components, and the first component has E-44 Resins, epoxy, E-51 Resins, epoxy, liquid polysulphide rubber, r-(2,3 epoxies, third amino) propyl trimethoxy silicane and tributyl phosphate, component B has dinoctyl phthalate, amine-phenolic condensation compound, T
31Epoxy hardener, Versamid, benzoic sulfimide, 2,4,6-three (dimethylamino methyl) phenol and activated magnesia, reduced iron powder is added in two components as counterweight, and making first and second liang of component weight ratios is 3: 1.
This metal adhesive is based on Resins, epoxy, and reason is that E-44 Resins, epoxy is good adhesive substrate, but its low temperature process performance is not really desirable, therefore uses E-51 Resins, epoxy and it compound again.Because the molecular weight of E-51 is slightly little, viscosity is also less, and low-temperature fluidity is better, can improve the blending process and the application property of adhesive like this, simultaneously owing to adjusted molecular weight distribution, thereby has also improved the wetting property on adherend surface.Experimental results show that composite epoxy base-material effective than general single epoxy base material.
Though Resins, epoxy intensity height, cementability is good, but still has shortcomings such as easily aging, that curing back property is crisp.Use the liquid polysulphide rubber modification, can improve its toughness and ageing resistance greatly.Because the thiorubber good springiness, ageing resistance is good.Thiorubber after participating in solidifying and vulcanizing has improved the interior poly-state of the solidification internal stress of glue-line, so improved cementitious thermotolerance and reliability.The general molecular weight that adopts gets final product at 3000-4000 (as JZY-124).
R-(2,3 epoxies, third amino) propyl trimethoxy silicane is a kind of organo-silicon coupling agent, and it glues material with transfer method coupling glue and quilt in tackiness agent, and can soak into and improve interfacial state, increases adhesive effect, also can improve the glue-applying technique performance of preparation simultaneously.
The liquid polymeric amide of low molecule is good ambient cure agent, simultaneously because itself has snappiness preferably, after participating in solidifying, the plasticity of glue is increased, because this plasticity is created in the structure after the curing, therefore plays a kind of self-plasticizing action again.This internal plasticization attribute that this glue has is not moved it, so can improve cementitious resistance to deterioration.
Benzoic sulfimide is nontoxic solidifying agent, and it and polymeric amide, r-(2,3 epoxies, third amino) propyl trimethoxy silicane and softening agent cooperatively interact effective, can improve adhering speed and adhesive effect.
Tributyl phosphate and dinoctyl phthalate all are softening agent, add the plasticity that can further improve glue in this glue.The former increases the induced dipole of molecule because the existence of phosphate radical is arranged, and can strengthen and intermetallic interaction force, thereby can improve adhesive effect, accelerates curing speed.The latter further improves the glue-applying technique performance of preparation because molecular chain length is flexible good.Its neighbour phthalic acid dibutyl ester has more persistent plastification, and is difficult for being moved.
The adding of activated magnesia can improve the heat-resistant stability of glue, and it can vulcanize thiorubber again simultaneously, improves cementitious over-all properties.
Add reduced iron powder, at first can reduce the electropotential of adhesively bonded joint, prevent the development of electrochemical process, also can increase intermetallic molecular force simultaneously, and reduce cure shrinkage, increase the hardness and the cohesive strength of glue-line, also can reduce the cost of glue.
The homemade solidifying agent that is added in this adhesive is a kind of amine-phenolic condensation compound, modification at normal temperatures and cured epoxy resin, improve the intensity and the hardness of epoxy glue, dexterously phenolic structure is introduced in the amine curing agent, can also use simultaneously with multiple properties-correcting agent again, improve glue to the stability of chemical mediator and thermotolerance etc., improved the over-all properties of this glue significantly, and make usually the glue of can only many components and depositing become two components, guarantee storage period, helped the use and the commercialization of this glue.
The optimum combination of solidifying agent, softening agent and Recipe that this adhesive is used has all broken through traditional pattern, has adopted the composite curing principle, and the allotment scope is big, and is easy to use, and bonding force is strong.At ambient temperature, solidified the tensile strength 〉=23.5MPa of bonding 45# steel, shearing resistance 〉=15MPa in this glue 2-3 hour; Shearing resistance 〉=the 12.3MPa of bonding aluminium alloy.In that " the sticking aluminium shearing resistance of " YY-921 " the two component glue on the 830th page of the adhesive applications handbook is 8-9MPa only.This glue is compared with the poly-sulphur two-component adhesive product of similar both at home and abroad epoxy, all has remarkable advantages at aspects such as condition of cure, curing speed, mechanical strength, costs.
