Abstract
The invention provides a superstrength anaerbic adhesive capable of fast curing under low temperature and a preparation method. The anaerbic adhesive is prepared by the following steps: mixing dimethacrylates monomer with EDTA disodium salt at the temperature of 60-90 DEG C and stirring the mixture for 1-3h; adding organic hydrazide, organic acid, O-sulfonylbenaylsuamine, unsaturated polyester resin and aerosil into the above solution to be stirred until the ingredients are fully dissolved, and cooling the ingredients to room temperature; adding organic peroxide into the solution and evenly stirring the mixture. The anaerbic adhesive is fast cured into thermoset plastics under low temperature, which has superstrength after curing, saves working time and reduces cost.
Description
Technical field
The present invention relates to a kind of glue and preparation method, relate in particular to quick-setting anaerobic glue of low temperature of a kind of superstrength and preparation method thereof.
Background technology
Along with the development of modern science and technology, anaerobic adhesive has played more and more important effect in people's life.Especially in automobile industry, the track traffic industry, anaerobic glue has replaced traditional locking seal means, has not only guaranteed quality, has also reduced cost, has made things convenient for workman's operation.A large amount of in the market what exist is the safe product of pleasure under the Henkel KGaA, and the various homemade anaerobic glue of domestic big or small manufacturer production.These anaerobic glues are in the lower area of northern temperature, and curing speed can be very slow, influenced construction speed, also influenced final strength simultaneously.Though the existence of the promotor that cooperates is with it arranged at present, has increased cost like this.
Summary of the invention
The quick-setting anaerobic glue of low temperature that the purpose of this invention is to provide a kind of superstrength is to solve the difficult problem that present anaerobic glue low-temperature curing speed is slow, intensity is low.
Another object of the present invention provides a kind of preparation method of above-mentioned anaerobic glue.
The quick-setting anaerobic glue of the low temperature of superstrength of the present invention, this anaerobic glue is composed of the following components by weight:

Above-mentioned methacrylic acid diester monomer is polyoxyethylene glycol methacrylic acid diester, multicondensed ethylene glycol double methyl methacrylate, ethoxyquin bisphenol a dimethacrylate, trimethylolpropane trimethacrylate, 1,3-butylene glycol dimethacrylate, 1, the mixture of one or more in 4-butylene glycol dimethacrylate, polyurethane-type polymethacrylate, hydroxyethyl methylacrylate or the tetraethylene-glycol dimethacrylate.
Above-mentioned organic hydrazides is benzoyl hydrazine or pyrodin.
Above-mentioned organo-peroxide is isopropyl benzene hydroperoxide or tertbutyl peroxide.
Above-mentioned organic acid is acrylic or methacrylic acid.
Above-mentioned unsaturated polyester is the fumaric acid bisphenol a resin.
The method for preparing the quick-setting anaerobic glue of low temperature of above-mentioned a kind of superstrength: this method is made up of following steps successively:
(a) methacrylic acid diester monomer and disodium EDTA are mixed stirring 1～3 hour under 60～90 ℃;
(b) with organic hydrazides, organic acid, adjacent benzoyl sulfimide, unsaturated polyester resin and aerosil, join be stirred to whole dissolvings in the above-mentioned solution after, be cooled to room temperature;
(c) adding organo-peroxide again in this solution stirs.
The invention has the beneficial effects as follows by preferable methyl diester acrylate monomer, select specific promotor simultaneously for use, stablizer, fast setting becomes thermosetting resin at low temperatures, has superstrength after the curing, has saved the working hour and has reduced cost.
