Description
2268503 CYANOACRYLATE ADHESIVE COMPOSITION The present invention relates
to a cyanoacrylate adhesive composition having a weakened adhesion to the skin
and can widely be used in various industries, medical fields, leisure fields, and household fields where cyanoacrylate adhesives are utilized as an instantaneous adhesive.
Cyanoacrylate adhesives containing 2-cyanoacrylate as a principal component have favorably been used in various industries, medical fields, leisure fields, and household fields as an instantaneous adhesive, since the adhesives have the property that 2-cyanoacrylate as a principal component is readily anionic-polymerized to rapidly cure in the presence of a very small amount of moisture or a basic substance.
However,, 2-cyanoacrylate adhesives have such problems that the adhesives bond a part of the skin with another part of the skin of a person who handles the adhesive or that the adhesives bond the skin with other adherends than the skin if the adhesives were used incorrectly. while the adhesives have such a convenient property that they can join glass, metal, plastic, wood, fabric, and paper instantaneously.
The troubles are caused by the existence of moisture and basic substances contained in sweat and secretions on the surface of human skin. The moisture and basic substances accelerate anionic polymerization of 2 cyanoacrylate adhesives so that the skin is readily bonded.
Since the skin adheres to another part of the skin or other adherends through 2-eyanoacrylate adhesives with a high bonding strength, if the adhered skin was forced to be torn off, the skin or subcutaneous tissue may be seriously injured.
Based on the background mentioned above, the development of an instantaneous adhesive is strongly desired, which lowers such a trouble that the adhesive adheres to the skin at the time of adhesion operation and which can be handled more easily and safely than conventional instantaneous adhesives.
As a result of the study to solve the problems mentioned above, it has been found that a cyanoacrylate adhesive composition containing at least one specific aliphatic alcohol, aliphatic carboxylic acid ester, or carboxylic acid ester of a carbocyclic compound has a low bonding rate on the skin, but bonds adherends other than the skin such as woods, plastics, rubbers, metals, and ceramics instantaneously.
The present invention relates to a cyanoacrylate adhesive composition having a lowered adhesion to the skin, which comprises at least one compound selected from the groups mentioned below and an anionic polymerization accelerator:
A: An aliphatic alcohol in which the aliphatic group contains 6 or more carbon atoms directly bonded with each other; B: An aliphatic carboxylic acid ester in which the aliphatic group contains 6 or more carbon atoms directly bonded with each other; C: An aliphatic carboxylic acid ester having at least 2 aliphatic groups in which the aliphatic group contains 4 or more carbon atoms directly bonded with each other; and 35 D: A carboxylic acid ester of a carbocyclic compound having an aliphatic group as a carboxylic acid residue or an alcohol residue, in which said aliphatic group contains 5 or more carbon atoms directly bonded with each other.
The adhesive composition of the present invention will 5 be described in detail below.
A principal component of cyanoacrylate adhesives is a 2-cyanoacrylate. Various kinds of 2-eyanoacrylatds can be used as a principal component even in the adhesive composition of the present invention as in conventional cyanoacrylate adhesives, and specific examples of the 2cyanoacrylates include methyl, ethyl, chloroethyl, npropyl, i-propyl, allyl, propargyl, n-butyl, i-butyl, npentyl, n-hexyl, cyclohexyl, phenyl, tetrahydrofurfuryl, heptyl, 2-ethylhexyl, n-octyl, n-nonyl, oxononyl, n-decyl, n-dodecyl, 2- ethoxyethyl, 3-methoxybutyl, 2-ethoxy-2ethoxyethyl, butoxy-ethoxy-ethyl, 2,2,2-trifluoroethyl, or hexafluoroisopropyl ester of 2-cyanoacrylic acid.
Specific examples of the aliphatic alcohol, under the Group A mentioned above, having an aliphatic group in which 6 or more carbon atoms are directly bonded with each other include monohydric alcohols, such as n-hexyl alcohol, n octyl alcohol, n-nonyl alcohol. 2-nonyl alcohol, decyl alcohol (decanol), lauryl alcohol (dodecyl alcohol/ dodecanol), tridecyl alcohol (tridecanol), tetradecyl alcohol, pentadecyl alcohol, Pcitronellol, 9-decene-l-ol, 1,1-dimethyl-5-methyl-6-heptene-l-ol, dihydromyrcenol. geraniol, 1,5-dimethyl-l-vinyl-4-hexene-l-ol, and coundecenyl alcohol. While alcohols mentioned above are preferable in the present invention, the aliphathic alcohol is not restricted to such alcohols.
The alcohol used in the present invention is an aliphatic alcohol having an aliphatic group in which 6 or more carbon atoms are directly bonded with each other. If all of the aliphatic groups in the molecule have 5 or less carbon atoms directly bonded with each other, the bonding rate on the skin becomes fast and troubles are caused at the time of adhesion operation so that such alcohols can not be used to achieve the purpose of the present invention.
Conversely. when the alcohol has, in its molecule, an aliphatic group in which 16 or more carbon atoms are bonded, the solubility of the alcohol in a cyanoacrylate becomes worse. Accordingly, aliphatic alcohols used for the present invention preferably have an aliphatic group in which 15 or less carbon atoms are directly bonded with each other, and more desirably the alcohols have an aliphatic group in which 8 to 15 carbon atoms, particularly, 9 to 15 carbon atoms are directly bonded with each other.
As will be clear from the specific examples mentioned above, the aliphatic group is preferably a hydrocarbon group (linear or branched polymethylene or polyolefin).
when the amount of the aliphatic alcohol to be added to the adhesive composition of the present invention is small, a sufficient inadhesiveness to the skin can not be obtained. When the amount is too much, however, the bonding rate on adherends other than the skin becomes slow, and thus, it is desirable to adjust the concentration of the alcohol in the cyanoacrylate adhesive composition to 10 to 40 % by weight, and more desirably to 15 to 30 % by weight.
Specific examples of the aliphatic carboxylic acid ester, under the Group B mentioned above,, having an aliphatic group in which 6 or more carbon atoms are directly bonded with each other, and examples of the aliphatic carboxylic acid (ster, under the Group C mentioned above, having at least 2 aliphatic groups in which 4 or more carbon atoms are directly bonded with each other include the following compounds:
Monocarboxylic acid ester Cetyl 2-ethyl hexylate, methyl ester of coconut fatty acid, methyl laurate, isopropyl myristate, methyl caprate, methyl oleate, isobutyl oleate, octyl oleate, 2-ethylhexyl crotonate, octyl acrylate, decyl methacrylate, tridecyl methacrylate, lauryl methacrylate,'and lauryl propiolate.
PolycarboUlic acid ester Bis(2-ethylhexyl) adipate, bis(2-ethylhexyl) maleate, dimethyl sebacate, bis(2-ethylhexyl) sebacate, bis(2- ethylhexyl) decamethylenedicarboxylate, 2,2,4-trimethyl1,3pentanediolmonoisobutylate, 2,2,4-trimethyl-1,3pentanedioldiisobutylate, triglyceride 2-ethyl hexanoate, triglyceride caprylate, diglyceride caprylate, and triglyceride caprate.
Carboxylic acid ester having at least 2 aliphatic groups Diisobutyl fumarate, diisobutyl maleate, tributyl acetyl citrate, and triglyceride caproate.
As explained above, the aliphatic carboxylic acid ester used in the present invention has an aliphatic group in which 6 or more carbon atoms are directly bonded with each other. or has at least 2 aliphatic groups in which 4 or more carbon atoms are directly bonded with each other.
When all of the aliphatic groups in the molecule has 5 or less carbon atoms directly bonded with each other, or the aliphatic carboxylic acid ester does not have at least 2 aliphatic groups in which 4 or more carbon atoms are directly bonded each other, the bonding rate on the skin becomes high and troubles are apt to be caused at the time of adhesion.
However, when the aliphatic group present in the molecule has 16 or more carbon atoms directly bonded with each other, the solubility of the aliphatic carboxylic acid ester in a cyanoacrylate becomes poor. Thus, the number of the carbon atomsdirectly bonded in the aliphatic group is preferably 15 or less. and more preferably 8 to 13. The aliphatic carboxylic acid ester is preferably 150 to 2000 in terms of molecular weight.
Further, as to the aliphatic carboxylic acid ester having at least 2 aliphatic groups in which 4 or more carbon atoms are directly bonded with each other, the ester having at least 3 aliphatic groups are preferably used in the present invention.
The aliphatic carboxylic acid ester mentioned above is added in the cyanoacrylate adhesive composition preferably in an amount of 1 to 40 % by weight, and more preferably 5 to 30 % by weight, since when the amount is small, a sufficient inadhesiveness can not be obtained, while when the amount of the ester to be added is too large, the bonding rate on adherends other than the skin becomes slow.
The carbocyclic carboxylic acid ester. under the Group D, having, in a carboxylic acid residue or alcohol residue. an aliphatic group in which 5 or more carbon atoms are directly bonded with each other is an ester of a carbocyclic carboxylic acid with an alcohol. Specific examples of the acid and the alcohol include the following compounds:
Carbocyclic carbogylic acid Benzoic acid, o-toluic acid, m-toluic acid, p-toluic acid, o- chlorobenzoic acid, salicylic acid, anisic acid, vanillic acid, veratric acid, peperonylic acid, protocatechuic acid, gallic acid, syringic acid, cyclohexane carboxylic acid, 3-biphenyl carboxylic acid, 1,5-naphthalene dicarboxylic acid, 2-naphthalene hexanoic acid, 1,3,6-naphthalene triacetic acid, camphoric acid, phthalic acid, isophthalic acid, terephthalic acid, 5 hemimellitic acid, trimellitic acid, trimesic acid, prehnitic acid, mellophanic acid, pyromellitic acid, benzene pentacarboxylic acid, mellitic acid, phenyl acetic acid, hydrocinnamic acid, V-phenyl butyric acid, d-phenyln-valerianic acid, c-phenyl-n-capric acid, cinnamic acid, phenyl propiolic acid, homophthalic acid, o-phenylene diacetic acid, m- phenylene diacetic acid, p-phenylene diacetic acid, o-phenylene acetic acid-p-propionic acid, cinamal malonic acid, w-phenyl-n-propyl malonic acid, acetyl cumaric acid, and cochenilic acid.
Alcohol n-pentyl alcohol, n-hexyl alcohol, n-octyl alcohol, 2ethylhexyl alcohol, n-nonyl alcohol, isononyl alcohol, decyl alcohol, isodecyl alcohol, tridecyl alcohol, tetradecyl alcohol, pentadecyl alcohol, P-citronellol, 9decene-l-ol, 1,1- dimethyl-5-methyl-6-heptene-l-ol, geraniol, 1,5-dimethyl-l-vinyl-4-hexene- l-ol, and wundecenyl alcohol.
In the carbocyclic carboxylic acid ester, under the Group D, used in the present invention, the aliphatic group in which 5 or more carbon atoms are directly bonded with each other may present in a carboxylic acid residue, for instance, between a carbon ring and a carboxyl group as a substituent on the carbon ring, or may exists in an alcohol residue. In the present invention, the ester prepared by using an alcohol having an aliphatic group in which 5 or more carbon atoms are directly bonded with each other is preferable, and specific examples of such ester include the following compounds.
Carbocyclic carboxylic acid ester Dihexyl phthalate, diheptyl phthalate, dioctyl phthalate, bis(2-ethylhexyl) phthalate, diisononyl phthalate, diisodecyl phthalate, diisotridecyl phthalate, dipentadecyl phthalate,, dioctyl terephthalate. diisononyl isophthalate, decyl toluylate, bis(2-ethylhexyl) camphorate, 2-ethylhexyl cyclohexyl carboxylate, 2ethylhexylbenzoate, bis(2-ethylhexyl) pyromellitate, and tris(2-ethylhexyl) trimellitate.
If the carbocyclic carboxylic acid ester having only aliphatic group in which less than 5 carbon atoms are directly bonded with each other is used, the bonding rate of the adhesive to the skin becomes high and the purpose of the present invention can not be attained.
In order to bring the effect of the present invention into fully play, it is preferable to use a carbocyclic -carboxylic acid ester having an aliphatic group in which 6 or more, more desirably 8 or more, particularly 9 or more carbon atoms are directly bonded with each other.
However, when the carbocyclic carboxylic acid ester having an aliphatic group in which too many carbon atoms are directly bonded with each other was used as the ester in the present invention, the solubility of the ester in a cyanoacrylate becomes poor, and there is a fear that troubles are produced in the preparation of the adhesive.
Thus, the carbocyclic carboxylic acid ester to be used in the present invention preferably has only aliphatic group in which less than 15 carbon atoms are directly bonded with each other, and more preferably less than 13 carbon atoms.
Specific examples of preferable carbocyclic carboxylic acid ester in the present invention include bis(2ethylhexyl) phthalate, diisononyl phthalate, diisodecyl phthalate, diisotridecyl phthalate, and tris(2ethylhexyl) 5 trimellitate.
The amount of the carbocyclic carboxylic acid ester to be added in the present invention is preferably 1 to 40 % by weight, and more preferably 5 to 30 % by weight in the cyanoacrylate adhesive composition. When the amount is small, a sufficient inadhesiveness can not be obtained, while the amount is too much, the bonding rate on adherends other than the skin becomes slow.
It was known that when an anionic polymerization accelerator was blended in a cyanoacrylate adhesive, the bonding rate of the cyanoacrylate adhesive on the skin or on other substances became fast. However, as a result of the study by the present inventors, it has been found that when at least one specific aliphatic alcohol, aliphatic carboxylic acid ester, or carbocyclic carboxylic acid ester as well as an anionic polymerization accelerator were added together to a cyanoacrylate adhesive, the effect of increasing the bonding rate on the skin is low, while the effect of increasing the bonding rate on adherends other than the skin, such as woods, plastics, rubbers, and ceramics is excellent, leading to the preparation of an excellent adhesive of the present invention.

As a fifth anionic polymerization accelerator, a cyclosulfur compound can be mentioned, and the known compounds disclosed, for example, in Japanese Unexamined Patent Publication (Kokai) No. 59-64681 can all be used.
They are cyclosulfur compounds having polysulfide linkage and ether linkage in the molecule, and represented by formula (3).
(R 60), R 7 S.__ (3) wherein R6 and R7 represent hydrocarbon chain having 2 to 6 carbon atoms. m represents an integer of 2 to 4. and n represents an integer of 1 to 3.

When the amount of the anionic polymerization accelerator to be added is smaller than 10 ppm,, rapid cureability of the adhesive can hardly be obtained, while when the amount exceeds 100,000 ppm, the bonding strength and storage stability of the adhesive considerably decrease and much improvement in cureability is no longer expected.
As in conventional cyanoacrylate adhesives, it is preferable to include a very small quantity of, for example, hydroquinone or sulfurous acid gas as a polymerization inhibitor in the cyanoacrylate adhesive composition of the present invention to improve the storage stability.
While 2-cyanoacrylate is inherently a colourless, transparent liquid substance having a low viscosity, a better effect can be obtained when it is made into a viscous or thixotropic liquid by dissolving or dispersing a thickener such as polymethyl methacrylate, acrylic rubber, cellulose derivative, and fumed silica in the present adhesive composition.
Further, the cyanoacrylate adhesive composition of the present invention can be coloured by a specific dye.
While any mechanism has not yet been elucidated, the cyanoacrylate adhesive composition of the present invention exhibits a very remarkable behavior that it shows an excellent instantaneous adhesive property for adherends other than the skin, such as woods, plastics, rubbers, metals. and ceramics, but does not show the instantaneous adhesion property for the skin.
The cyanoacrylate adhesive composition of the present invention will decrease the trouble of "skin adhesion" upon adhesion operation. Thus, the cyanoacrylate adhesive composition of the present invention has advantages that it can widely be used in more applications than conventional cyanoacrylate adhesives and that it can be used more safely. in a house or school for bonding stationery as well as in various industries, medical fields and leisure fields.

(1) Method for determining set time: (Rigid polyvinyl chloride) Test specimens of rigid polyvinyl chloride were pasted together with an adhesive in accordance with the method of JIS K 6849 and the time when the bonding strength reaches a 25 value of higher than 3 kg was assumed to be the set time.
(Balsa, chloroprene rubber) Test specimens were pasted together with an adhesive in accordance with the method of JIS K 6850 and the time when the bonding strength reaches such a degree that the test specimens can not be detached by lightly pulling them by hands toward the direction of a major axis of the test specimens was assumed to be the set time.
(Finger) An adhesive was applied on the surface of a forefinger, the adhesive was spreaded to form a thin film by pressing lightly with a thumb, and the time (t) when the forefinger is separated from the thumb by their own ability without pain, was determined at 5 ranks of t 5 1 sec, 1 sec < t s 15 sec, sec < t 5 30 sec, sec < t s 60 sec, and sec < t.
Environment for the determination was adjusted to a temperature of 230C and humidity of 60 % RH.
The results of the tests are shown in Tables 7, 8, and 9.
