The present invention relates to an ultraviolet curable adhesive composition having a specific composition. In recent years, instead of thermosetting adhesives, the use of ultraviolet curable adhesives has been considered in the field of components that are transparent to ultraviolet rays and can be cured by irradiation with ultraviolet rays. Thermosetting adhesives usually need to be kept at high temperatures for long periods of time to cure and bond, but with UV-curable adhesives, adhesion or position fixation is achieved by irradiating UV light for seconds at room temperature. This makes it possible to significantly improve work efficiency and significantly reduce energy consumption. However, on the other hand, UV-curable adhesives have problems such as increased internal strain due to the curing reaction occurring in seconds, making it impossible to obtain sufficient adhesive strength. The inventors of the present invention have conducted intensive studies in order to obtain a highly practical adhesive composition that eliminates these problems while providing the characteristics of ultraviolet curing, and as a result, they have succeeded in developing a composition that meets the purpose. did. The present invention is as follows. An ultraviolet curable adhesive composition containing the following [A] to [D]. [A] 100 parts by weight of ethylenically unsaturated bond-containing unsaturated polyester with a molecular weight of 1,000 to 10,000 [B] The following formula [In the formula, A represents a saturated or unsaturated alkylene group having 2 to 28 carbon atoms which may have a substituent, and R represents a hydrogen atom or a methyl group. ] 30 to 100 parts by weight of di(meth)acrylate [C] 20 to 100 parts by weight of hydroxyalkyl (meth)acrylate [D] The following formula [In the formula, Ar is a phenyl group that may have a substituent, R is a hydrogen atom or a methyl group, and n is 1 to
Represents an integer of 5. ] Phenoxy derivative represented by 20 to 100 parts by weight In this specification, "(meth)acrylate" is used to mean acrylate or methacrylate. The composition of the present invention can be effectively used not only for its original adhesive use of bonding two base materials, but also for so-called one-sided adhesive use, where it is applied to the surface to protect the surface, impart gloss, impart corrosion resistance, etc. be able to. When using the composition of the present invention, adhesion is performed by ultraviolet irradiation in seconds, so workability is greatly improved, energy is saved, and adhesive strength sufficient for practical use can be obtained. Essential component [A] in the composition of the present invention
[D] will be explained. [A] Component This component is an ethylenically unsaturated bond-containing unsaturated polyester having a molecular weight of 1,000 to 10,000. This product combines unsaturated dibasic acids such as phthalic anhydride, isophthalic acid, maleic anhydride, and fumaric acid with diols such as propylene glycol, ethylene glycol, or bisphenol A, and tetrabutyl zirconate, tetraoctyl titanate, etc. It is produced by esterification in the presence of a catalyst. Usually acid number 10
~60 or so are advantageously used. As is well known, many unsaturated polyesters are commercially available in the form of solutions diluted with polymerizable monomers such as styrene. It is desirable to use it in a form that does not contain the above polymerizable monomer. [B] Component This component is expressed by the following formula (The meanings of the symbols are as described above.) It is a di(meth)acrylate represented by the following. The method for producing this product is as follows, taking as an example the case where diacrylate is obtained using succinic acid as a dibasic aliphatic acid as a starting material. Examples of dibasic aliphatic acids include saturated acids such as succinic acid, glutaric acid, adipic acid, dimethyladipic acid, suberic acid, ethylpropylglutaric acid, and brassylic acid (tridecanedioic acid), as well as heptenedioic acid and dimethyloctenedioic acid. Unsaturated acids such as , undecanedioic acid, pentadecanedioic acid, etc. are used. Among these, it is generally advantageous to use saturated or unsaturated acids having 10 to 30 carbon atoms. In this case, the number of carbon atoms in the alkylene group of A in the above formula of the obtained component [B] will be 8 to 28. Although dibasic aliphatic acids of this type can be used as single compounds, it is advantageous to use them in the form of mixtures. As a mixture,
For example, there is an aliphatic acid mixture obtained by reacting cyclohexanone with Fenton's reagent, and this mixture is commercially available. [C] Component This component is a hydroxyalkyl (meth)acrylate, which is produced, for example, from acrylic acid or methacrylic acid and ethylene oxide or propylene oxide. Specifically, β
-Hydroxyethyl (meth)acrylate, β-
Examples include hydroxypropyl (meth)acrylate. [D] Component This component is expressed by the following formula (The meanings of the symbols are as above) A phenoxy derivative represented by
Each of these may be used alone, or a mixture thereof may be used. This product is produced by dehydration condensation of a polyethylene oxide derivative of the following formula ArO(CH 2 CH 2 O) o H and acrylic acid or methacrylic acid. The components [A] to [D] are essential to the composition of the present invention. In other words, unsaturated polyester [A] is a resin that is solid or highly viscous at room temperature, and it must be diluted to reduce the viscosity to a level suitable for handling. It must be able to do this without impairing the adhesive properties inherent to unsaturated polyester. Among various compounds having ethylenically unsaturated bonds, hydroxyalkyl (meth)acrylates [C] and phenoxy derivatives [D] are particularly selected as diluents suitable for this purpose. However, [A], [C],
[D] The cured product obtained from the three-component composition is generally brittle and does not necessarily have sufficient adhesive properties. Therefore, di(meth)acrylate [B] was further added, and as a result, the adhesiveness was greatly improved, and [A]
The ultraviolet curable composition of the present invention containing component ~[D] can exhibit excellent adhesive properties. Regarding the content of the composition of the present invention, the di(meth)acrylate [B] is 30 to 100 parts by weight per 100 parts by weight of the unsaturated polyester [A]. [B]
If the amount of ingredients is less than 30 parts by weight, the adhesiveness will decrease,
If it exceeds 100 parts by weight, the hardness of the cured product will decrease significantly. Hydroxyalkyl (meth)acrylate [C] and phenoxy derivative [D] are each
20 to 100 parts by weight. If [C] or [D] is less than 20 parts by weight, the diluting effect on the unsaturated polyester will not be sufficiently exhibited and the viscosity of the composition will be too high, resulting in poor workability and poor wetting with the substrate. Poor adhesion results. If it exceeds 10 parts by weight, the dilution becomes excessive and the crosslinking density in the cured product decreases, resulting in a decrease in ultraviolet curability and adhesive strength. The relative amount ratio of hydroxyalkyl (meth)acrylate [C] and phenoxy derivative [D] is:
[C]/[D]=1/0.3 to 1/3 is advantageous. The composition of the present invention may contain other substances as described below, if desired. In order to adjust the viscosity or leveling property, 2-
Ethylhexyl acrylate, tetrahydrofurfuryl acrylate, α-methylstyrene, N-
Low viscosity monofunctional monomers having one ethylenically unsaturated bond such as vinylpyrrolidone are used to increase the curing speed or strength of the cured product. A polyfunctional monomer having multiple ethylenically unsaturated bonds such as pentaerythritol hexaacrylate can be mixed. These monofunctional monomers or polyfunctional monomers can be added to the total weight of the composition consisting of the essential components.
It is desirable to contain within 10 parts of each. It is advantageous to add to the compositions of the invention photosensitizers effective for accelerating UV curing of compounds containing ethylenically unsaturated bonds. For this purpose, ketones such as benzophenone, benzyl, Michler's ketone, benzoins such as benzoin, benzoin methyl ether, benzoin ethyl ether, benzoin isopropyl ether,
Quinones such as naphthoquinone, 2-tert-butylanthraquinone and acenaphthenequinone, and heterocyclic compounds such as xanthone, thioxanthone and 2-chlorothioxanthone can be used. Further, when ultraviolet irradiation and heating are used together in using the composition, it is preferable to add a thermosetting catalyst to the composition. As such a catalyst, a usual radical initiator is used, and specifically, ketone peroxides such as methyl ethyl ketone peroxide and cyclohexanone peroxide, diacyl peroxides such as acetyl peroxide and benzoyl peroxide, and tert-butyl hydroperoxide are used. oxide, hydroperoxides such as cumene hydroperoxide, di-tert-butyl peroxide,
Dialkyl peroxides such as dicumyl peroxide, alkyl peresters such as tert-butyl peracetate and tert-butyl perbenzoate, diisopropyl peroxide carbonate,
Examples include percarbonates such as bis(4-tert-butylcyclohexyl) peroxydicarbonate, azobisisobutyronitrile, and the like. In addition, it is advantageous to add a small amount of a thermal polymerization inhibitor to prevent the composition of the present invention from thermally curing during storage. This small amount of thermal polymerization inhibitor does not substantially inhibit curing by heating after irradiation with ultraviolet rays. Typical examples of such thermal polymerization inhibitors include hydroquinone, hydroquinone monomethyl ether,
Examples include phenothiazine and cuperone. Furthermore, in the composition of the present invention containing a thermosetting catalyst, an organic acid metal salt (metal soap) such as cobalt naphthenate, cobalt octenoate, manganese naphthenate, manganese octenoate, etc. is added as a curing accelerator.
It is also possible to add amines such as dimethylaniline, N-phenylmorpholine, trimethylbenzylammonium chloride, or quaternary ammonium salts thereof. In addition, as necessary,
It is also possible to use colorants such as organic/inorganic pigments and dyes, or thixotropic agents such as ultrafine silica. Furthermore, powders such as fused silica, magnesium silicate, or aluminum hydroxide may be added as inorganic fillers. All of the above-mentioned subsidiary components are commonly used in the technical field and are added in appropriate amounts depending on the purpose of use. The composition of the present invention can be used as an adhesive in its original sense, and can also be used as a surface coating agent, which can be referred to as one-sided adhesive. The composition is injected between adherends using a dispenser, or applied to adherends using a screen printing machine, roll coating method, or the like. The selection of the coating method is made according to the shape of the adherend. Examples of adherends include metals, plastics, glass, ceramics, and the like. The composition of the present invention is actually useful for fixing plastic cases and metal cases of electrical and electronic parts, adhering glass to glass, etc.
It can be used for a wide variety of purposes, such as fixing parts on solder resists of printed circuit boards and on printed circuit boards in the electronics industry. It goes without saying that the shape or material of the adherend is selected to be convenient for irradiating the applied ultraviolet curable adhesive composition with ultraviolet rays. For the ultraviolet irradiation, a chemical lamp, a medium-pressure/high-pressure mercury lamp, a xenon mercury lamp, a metal halide mercury lamp, etc., which provide light rays with a wavelength of 240 to 450 nm, are used as a light source effective for activating the photosensitizer. In addition, when the composition of the present invention contains a thermosetting catalyst, after irradiation with ultraviolet rays, if necessary, the composition may be placed in a hot air heating furnace, an infrared heating furnace, or a far infrared heating furnace at 40°C to 250°C, preferably at 80°C. It is advantageous to heat to between 180°C and 180°C to complete the curing. Hereinafter, the present invention will be explained with reference to examples, and comparative examples will be listed. Examples 1 to 3 and Comparative Examples 1 to 6 2.2 mol of diethylene glycol, 1 mol of maleic anhydride, and 1 mol of phthalic anhydride in a nitrogen stream at 190%
