Description
The invention belongs to the epoxy adhesive field.
Engineering adhesive must have good Joint strength and toughness, but also must have the processing performance that is suitable for constructing.For example in the fabrication line of automobile, tackiness agent is carried with mechanical pump usually, therefore, requires tackiness agent to have lower viscosity.Splicing face is on the position perpendicular to ground under many situations, does not allow the tackiness agent trickling during curing.This just requires tackiness agent not only when mobile lower viscosity to be arranged, and can not trickle when static.
The tough epoxy tackiness agent that the invention provides a kind of single component, does not trickle, be characterized in having very high strength and toughness, have the viscosity that to carry with mechanical pump, and on surface, park for a long time at normal temperatures perpendicular to ground, when perhaps being heating and curing, do not trickle.This tackiness agent is made up of Resins, epoxy, snappiness microgel, reactive thinner, solidifying agent, curing catalyst, mineral filler, silane coupling agent etc.It is that the snappiness microgel combines with the suitable of mineral filler that the present invention is different from existing technical characterictic, tackiness agent is not only had satisfy bonding required bonding strength of engineering and toughness, and do not trickle when solidifying.
Because Resins, epoxy has highly cross-linked structure, though not toughness reinforcing epoxy adhesive has higher shearing resistance, toughness is good inadequately.The toughness of tackiness agent is normally weighed with stripping strength.In order to improve the toughness of epoxy adhesive, can in resin, introduce the rubber disperse phase.
The preparation rubber-toughened epoxy resin use fluid rubber usually, for example, with liquid nbr carboxyl terminal as toughner.In solidification process, be separated, form the rubber disperse phase.Fluid rubber exists as toughner and is separated not exclusively and problem such as the rubber phase crosslinking structure is imperfect.Present inventors etc. are at the paper of publishing (Chin.J, Polym.Sci.) 1987,5(1), 76 and Angew.Makromol.Chem., 1989,171,65) proof can overcome the shortcoming of fluid rubber toughner in as the toughner of Resins, epoxy with the snappiness microgel.
The snappiness microgel is the rubber microballoon with crosslinking structure, and its second-order transition temperature is lower than-30 ℃.In Resins, epoxy, add the snappiness microgel, can improve the energy that material is absorbed greatly in destructive process, promptly improved the toughness of material widely.In addition, this crosslinked microballoon has very big specific surface area, and the interaction of the interaction between them and they and inorganic filler surface makes system have special rheological property.
For tackiness agent is not trickled, in system, must form the reversible physical structure.This texture ratio a little less than, under the effect of shearing force, take apart easily.Forming this physical structure method commonly used is to add solid packing in the tackiness agent of liquid state.The surface properties of solid packing and particle size distribution are for the decisive influence that is formed with of reversible physical structure.Clear and the 63(1988 of day disclosure special permission)-156,817 used the white carbon black handled through hydrophobic and silica powder as filler, preparation has good thixotropic epoxy adhesive.
The present invention is different from existing technology and is to adopt the snappiness microgel to combine with mineral filler, the character that system is had when static, do not trickle, and mineral filler needn't be passed through special surface treatment.
The Resins, epoxy that epoxy adhesive of the present invention adopted is the resin that has two above epoxy group(ing) in the molecule, comprises bisphenol A type epoxy resin, novolac epoxy, polyprotonic acid glycidyl ester type epoxy resin.This based epoxy resin can use separately, also can several mixed with resin use, so that obtain required performance.
The snappiness microgel that epoxy adhesive of the present invention adopted is the multipolymer of unsaturated polyester and vinyl monomer, and its particle diameter is in 50 millimicrons to 2000 millimicrons scopes.Second-order transition temperature is in-30 ℃ to-70 ℃ scopes.The umber of contained snappiness microgel can change in 5 parts to 50 parts scopes in per 100 parts (weight, down with) Resins, epoxy, and the over-all properties of tackiness agent is better in 10 parts to 30 parts scopes.
The dispersion system of preparation snappiness microgel in Resins, epoxy, can be according to the method that is adopted among aforementioned paper of having published of present inventor or the Chinese patent publication number CN1033062A, be about to unsaturated polyester and vinyl monomer and carry out emulsion copolymerization, then resulting microgel is separated, make solution, mix with Resins, epoxy again through behind the purifying, remove at last and desolvate.
The invention provides a kind of more easy method for preparing the dispersion system of snappiness microgel in Resins, epoxy, i.e. in situ polymerization method.The in situ polymerization method is unsaturated polyester and directly polymerization in Resins, epoxy of vinyl monomer, the preparation dispersion system.Compare with emulsion polymerisation process, can save microgel is separated from emulsion, make solution, mix and remove the step of complexity such as desolvating again with Resins, epoxy.
The technology for preparing the two-phase Polymer Systems by in situ polymerization is known, and for example United States Patent (USP) 4,708,996 and the method that proposed of European patent 137,634.In order to make disperse phase is the elastomerics microballoon with crosslinking structure, adds the polyfunctional group vinyl monomer usually, as Vinylstyrene or glycol methacrylate as linking agent.The control ratio of in situ polymerization is difficult in the presence of linking agent, and the gelation of whole polymkeric substance takes place easily.
Different with existing technology, dispersion system, the disperse phase of microgel of the present invention in Resins, epoxy is the multipolymer of unsaturated polyester and vinyl monomer.Here unsaturated polyester is the linking agent of snappiness microgel, and it plays the effect of dispersion stabilizer simultaneously again.So, the very easy control of unsaturated polyester of the present invention and the vinyl monomer in situ polymerization in Resins, epoxy, and resulting dispersion system is very stable.
The microgel of making by unsaturated polyester and vinyl monomer in situ polymerization, with add the resulting microgel of polyfunctional group alkene class linking agent copolymerization by vinyl monomer and compare, other has tangible characteristics, only some participates in copolymerization to two keys when in situ polymerization in the unsaturated polyester ester molecule, do not participate in that part of pair of key of polymeric when epoxy resin cure can with the amido generation addition reaction in the solidifying agent, therefore increased chemical bond combination firm in the two-phase interface.
By the prepared dispersion system of microgel in Resins, epoxy of in situ polymerization method of the present invention, except that being used for tackiness agent, can also be used for coating, matrix material and cast material etc.
