Description
The present invention relates to a kind of acrylate structural adhesive and manufacture method thereof of fine properties.
Since in 1974 du pont company takes the lead in developing s-generation acrylic ester adhesive (SGA), cause extensive attention, competitively study, improve various countries, has obtained many progress in all many-sides such as bounding force, stability, thermotolerances.Yet it is still unsatisfactory aspect package stability.General SGA product must stored below 20 ℃, though the SGA of Japan brings up to 25 ℃ with storage temperature, period of storage also has only three to six months.Close month type acrylate adhesive of last marine products storage temperature is no more than 20 ℃, and the phase of depositing only is half a year.Present SGA both domestic and external because package stability is failed fine solution, is subject to many limitations in storage, transportation, application facet, it is lower to add its sticking temperature, its tensile strength 〉=20-22Mpa, shear strength 〉=24-32Mpa has restricted applying of SGA.
The present invention just provides a kind of acrylate structural adhesive of fine properties, can store more than 2 years its cohesive force and equally matched before 2 years in subzero 20 ℃ to 35 ℃ temperature range.
The present invention is a kind of bi-component acrylic ester structure glue, and the proportioning of main glue and solidifying agent is: main glue 85-95%, and solidifying agent 3-18%, above-mentioned each component sum equals 100%.Wherein main glue component and proportioning are: methyl methacrylate 22-27%, methacrylic acid 22-27%, methacrylate ethyl ester 2-5%, Jia Jibingxisuanyizhi 2-5%, epoxy acrylate prepolymer 27-33%, methacrylic ester grafting paracril 3-6%, 304 polyester 2-5%, coupling agent KH570 (γ-methacrylate based Trimethoxy silane) 3-6%, antioxidant 264 (2,6-ditertbutylparacresol) 2-5%, and the special-purpose promotor of above total amount 9-18%.Curing agent component and proportioning are: cumene hydroperoxide hydrogen 32-38%, benzoyl peroxide 30-34%, cyclohexanone peroxide 30-36%, and the dibutyl phthalate of above total amount 3-9%.
The component and the proportioning of the special-purpose promotor of the present invention are: N, accelerine 70-80%, E51 Resins, epoxy (bisphenol A type epoxy resin) 20-30%.
The preparation method of master's glue of the present invention is: with methyl methacrylate, methacrylic acid, the methacrylate ethyl ester, Jia Jibingxisuanyizhi, epoxy acrylate performed polymer, methacrylic ester connect skill paracril, 304 polyester, coupling agent KH570, antioxidant 264, drop into reactor by aforementioned proportioning, stir under the normal temperature, drop into the special-purpose promotor of aforementioned proportioning again, stirred 56 hours with 110 rev/mins rotating speeds.The preparation method of solidifying agent is: with cumene hydroperoxide hydrogen, and benzoyl peroxide, cyclohexanone peroxide, dibutyl phthalate drops into reactor by aforementioned proportioning, stirs 40 hours with 70 rev/mins of rotating speeds under the normal temperature.The making method of special-purpose promotor is: with N, and accelerine, E51 Resins, epoxy joins in the reactor by aforementioned proportioning, and normal temperature stirred 32 hours down.
Acrylate structural adhesive of the present invention, the optimum formula of main glue is: methyl methacrylate 25%, methacrylic acid 25%, methacrylate ethyl ester 3%, Jia Jibingxisuanyizhi 3%, epoxy acrylate performed polymer 29%, methacrylic ester grafting paracril 4%, 304 polyester 3%, coupling agent KH5705%, antioxidant 264 3%, and the special-purpose promotor of aforementioned total amount 11%.The optimum formula of solidifying agent is a cumene hydroperoxide hydrogen 35%, benzoyl peroxide 32%, cyclohexanone peroxide 33%, and the dibutyl phthalate of above total amount 5%.The optimum formula of special-purpose promotor is: N, accelerine 75%, E51 Resins, epoxy 25%.
The present invention is monomer and performed polymer with the acrylate derivative with multi-functional high reactivity group, and with the elastomerics with unsaturated link(age), special-purpose promotor and other auxiliary agent constitute main glue according to a certain ratio.Superoxide adding assistant with the different transformation period is re-dubbed powerful redox system as solidifying agent.Because this kind system can play the initiation that comprehensively goes forward one by one, and has improved velocity of initiation, has reduced the consumption of initiator.When main glue mixes according to a certain ratio with solidifying agent, the rapid reaction under the initiation of solidifying agent of main glue, its elastomerics percentage of grafting reaches more than 95%.Thereby the adhesive property and the package stability of tackiness agent have been improved effectively.The cohesive strength height of acrylate structural adhesive of the present invention, after measured, can reach tensile strength 〉=25-39Mpa, shear strength 〉=28-36Mpa, with bonding one end have copper rod and the rod iron of the φ 40mm of 20mm wireline, with the reverse direction tractive of two lorries, the bonding part of wire cable rupture and copper rod and rod iron is excellent as a result.Acrylate structural adhesive of the present invention can be deposited in subzero 20 ℃ to 35 ℃ scope more than 2 years, and Ci Shi tensile strength and shear strength can reach 33.3Mpa and 32.3Mpa after measured.Not only cohesive force is strong owing to the present invention, and fine properties, will be widely used in temperature different each countries and regions and every field.
