The present invention relates to a reactive two-component adhesive comprising a main component of an acrylic monomer and an activator for initiating polymerization thereof. More specifically, it relates to improving the storage stability of the main ingredient. Reactive adhesives that substantially do not contain a solvent and are cured by polymerization of monomer components to strongly bond various types of adherends are known. For example, it is a two-component adhesive, in which the first component consists of an acrylic or methacrylic monomer and a peroxide or hydroperoxide, and the second component allows the polymerization of the acrylic or methacrylic monomer at room temperature. Consists of an activator to initiate. Here, the activator is preferably one that can provide sufficient adhesive strength even in a non-scientific amount relative to the monomer. U.S. Patent No. 3,890,407 (Japanese equivalent patent is JP-A-49-132119) discloses a sulfur-containing composition selected from the group consisting of chlorosulfonated polyethylene and a mixture of sulfonyl chloride and chlorinated polyethylene. An adhesive composition is shown comprising a solution of at least one polymerizable monomer selected from the group consisting of acrylic monomers and methacrylic monomers and a free radical generator. However, although this type of adhesive composition provides excellent bonding, it lacks long-term storage stability, and there is a need to improve this point. Adhesives need to have excellent performance such as adhesion speed and adhesive strength, and it is extremely important to maintain this performance for as long as possible. It is often observed that such adhesives gel in a relatively short period of time, that the adhesion speed becomes very slow, and that the adhesion strength decreases. U.S. Patent No. 3962372 (Japanese equivalent patent is Japanese Patent Publication No. 57-20347), U.S. Patent No. 3890407
A method for improving the shelf life of adhesive compositions has been proposed. According to this, 2,6-
Di-tert-butyl-4-methylphenol (BHT)
It is stated that the storage stability is improved if the weight ratio of organic hydroperoxide to organic hydroperoxide is 1:1 to 1:4. According to the inventors' investigation, the stability has certainly been improved, but in an accelerated storage test, 7 to 10
It was observed that it gelled within a few days. However, storage stability of this type of adhesive at 50 DEG C. for 7 to 10 days is insufficient in an accelerated test, and is required to last for at least 20 to 30 days. The present inventors conducted studies from various angles in order to significantly improve such insufficient storage stability, and as a result, they found that it was difficult to expect improvement with stabilizers such as BHT alone, and that the addition of organic tin compounds was necessary. It was found to be extremely effective. That is, the first invention of the present application is a reaction type 2 consisting of a main component consisting of an acrylic monomer or methacrylic monomer and an organic peroxide, and an activator that initiates polymerization of the acrylic monomer or methacrylic monomer at room temperature. In the component type adhesive, the main component is (A) at least one monomer selected from the group consisting of acrylic monomers or methacrylic monomers (B) chlorosulfonated polyethylene or organic chlorinated sulfonyl compound and chlorinated polyethylene (The ratio of component A and component B is 50 to 500 parts by weight of component A per 100 parts by weight of component B) (C) Organic peroxide (0.01 to 10% by weight of the main component) (D) Phenol System stabilizer (0.01 to 10% by weight of the main component) (E) A composition consisting of an organic tin compound (0.01 to 20% by weight of the main component), and the activator is a tertiary amine or aldehyde and a primary A reactive two-component adhesive characterized by being a condensation product with a primary amine or a secondary amine. The main component did not gel even after an extremely long period of time, and no decrease in adhesion speed or strength was observed. Examples of the acrylic monomer or methacrylic monomer used in the present invention include methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, and cyclohexyl (meth)acrylate.
Acrylate, 2-ethylhexyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, methoxyethyl (meth)acrylate, ethoxyethyl (meth)acrylate
Examples include acrylate, butoxyethyl (meth)acrylate, tetrahydrofurfuryl (meth)acrylate, (meth)acrylic acid, ethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, and these monomers can be used alone or in combination. You can. The mixture of chlorosulfonated polyethylene or organic chlorinated sulfonyl compound and chlorinated polyethylene used in the present invention is 25 to 75% by weight per 100 g of polymer.
of chlorine and 3 to 160 mmol of sulfonyl chloride moieties, and the chlorosulfonated polyethylene and chlorinated polyethylene are made from polyethylene having a melting coefficient of 4 to 500. Organic sulfonyl chloride compounds include, for example, toluenesulfonyl chloride, diphenyl ether-
4,4'-disulfonyl chloride and the like are suitable.
The ratio of the chlorosulfonated polyethylene or the mixture of the organic sulfonyl chloride compound and the chlorinated polyethylene to the polymerizable monomer is 50 to 500 parts by weight of monomer per 100 parts by weight of the polymer. Alternatively, organic peroxides and organic hydroperoxides are used as free radical generating agents in the present invention. Specific examples include benzoyl peroxide, t-butyl hydroperoxide, and yumenehydroperoxide, and the amount of these organic peroxides is 0.01 to 10% by weight of the base ingredient. Examples of the organic tin compounds used in the present invention include dibutyltin maleate, di-n-octyltin maleate, dibutyltin distearate, dibutyltin dinonylate, dibutyltin dilaurate, and tribenzyltin laurate.
The preferred amount of these organic tin compounds is 0.01 to 20% by weight of the main ingredient. Adding more than this is not preferable because the adhesive strength will decrease. The phenolic stabilizers used in the present invention to improve shelf life include hydroquinone, hydroquinone monomethyl ether, 2,6-di-t-
Examples include butyl-4-methylphenol, but the most preferred stabilizer is 2,6-di-t-butyl-4-methylphenol. The preferred amount of stabilizer is 0.01 to 10% by weight of the base ingredient. The main component of the first invention of the present application is a uniform mixture of acrylic monomer or methacrylic monomer, chlorosulfonated polyethylene or a mixture of sulfonyl chloride and chlorinated polyethylene, an organic peroxide, a stabilizer, and an organic tin compound. It can be easily manufactured. In addition, the present inventors have found that by adding an epoxy resin to the main component of the first invention of the present application described above, the storage stability can be further improved. This new phenomenon occurs only when an organic tin compound and an epoxy resin are used together, and no effect is observed when the epoxy resin is used alone. That is, the second invention of the present application is a reactive type consisting of a main component consisting of an acrylic monomer or methacrylic monomer and an organic peroxide, and an activator that initiates polymerization of the acrylic monomer or methacrylic monomer at room temperature. In a two-component adhesive, the main component is (A) at least one monomer selected from the group consisting of acrylic monomers or methacrylic monomers (B) chlorosulfonated polyethylene or organic chlorinated sulfonyl compound and chlorinated Mixture with polyethylene (ratio of component A and component B is 50 to 500 parts by weight of component A per 100 weight of component B) (C) Organic peroxide (0.01 to 10% by weight of the main component) (D) Phenol A composition consisting of a system stabilizer (0.01 to 10% by weight of the main component) (E) an organic tin compound (0.01 to 20% by weight of the total composition) (F) an epoxy compound (0.01 to 20% by weight of the main composition) It is a reactive two-component adhesive characterized in that the activator is a condensation product of a tertiary amine or aldehyde and a primary amine or secondary amine, and its main component is It has better stability over time than the main ingredient of the first invention of the present application. Commercially available epoxy resins are suitable as the epoxy resin used in the present invention, examples of which include polyglycidyl ether and polyglycidyl ester, and they may be in either liquid or solid form. By adding and mixing an epoxy resin to the base component of the first invention of the present application, the base component of the second invention of the present application can be obtained.
It is 0.01-20% by weight. The activator compound that initiates the polymerization of the main component consisting of the acrylic monomer or methacrylic monomer obtained in this way is, for example, a tertiary amine (for example, N,
N'-dimethylaniline, N,N'diisopropyl-P-toluidine) or condensation products of aldehydes with primary or secondary amines (e.g. condensation products of butyraldehyde with aniline or butylamine; Exemplary compounds include DuPont's Activators 808 and 833. Adhesion is achieved immediately by applying the base component to one side of the adherend, applying a thin layer of activator to the other side, and pressing both sides together. Polymerization occurs and the bond forms within a few minutes.
Maximum adhesive strength is reached in 24 hours. The amount of the activator to be used is preferably 15 parts by weight at most, preferably 0.01 to 1.5 parts by weight, per 100 parts by weight of the main ingredient. According to the present invention, an accelerator is used in conjunction with an activator to increase the rate of adhesive curing. Suitable promoters include oxidizing compounds of transition metals. For example, copper naphthenate, cobalt naphthenate,
Included are complex compounds of iron naphthenate, nickel naphthenate, or acetylacetone with iron, copper, cobalt, or vanadium. Since the adhesive of the present invention has high adhesive strength,
Suitable as a structural adhesive for steel-to-steel bonding, etc. The effects of the present invention will be shown below through examples. The activator compound used was Dupont's activator.
808 was used. Further, the adhesive effect was evaluated by the following accelerated test method. Examples 1 to 9, Comparative Examples 1 to 2 50 parts by weight of methyl methacrylate, 10 parts by weight of 2-ethylhexyl methacrylate, 2 parts by weight of ethylene glycol methacrylate, 1 part by weight of trimethylolpropane trimethacrylate, and 7 parts by weight of methacrylic acid were uniformly mixed. To 70 parts by weight of the monomer composition prepared above, chlorosulfonated polyethylene, organic peroxide, BHT, and organic tin compound shown in Table 1, or Epicoat 828 were added and mixed uniformly to obtain each adhesive. Table 1 shows the results of a storage test using these adhesives.
