【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a 2-cyanoacrylate adhesive composition. 2-Cyanoacrylate adhesives exhibit adhesive ability by instantaneously polymerizing and curing at room temperature using moisture in the atmosphere or trace amounts of moisture adsorbed on the surface of adherends, so they are widely used in various industrial fields for plastics, It is widely praised for its instant adhesive properties for bonding rubber, glass, metal, etc. However, peel resistance and impact resistance are not necessarily satisfactory, and as a result, it is currently considered that there are problems in using it in areas that require a high degree of adhesive strength, and the original purpose of adhesion is There are cases in which it is used only for temporary fixing purposes rather than for temporary fixing purposes, which has the problem that it is not always satisfactory. 2-cyanoacrylate adhesives are usually made of 2-cyanoacrylate as the main component, to which small amounts of stabilizers, thickeners, plasticizers, etc. are added. There is a tendency that the higher the purity of cyanoacrylate, the better the performance as an instant adhesive. Therefore, when other ingredients are added to improve this adhesive, it loses its original properties of instant adhesiveness or lacks storage stability.
Various attempts to improve the properties of cyanoacrylate adhesives by adding other ingredients have been extremely difficult and rarely successful. The inventors wanted to improve the properties of adhesives by adding additives, but the original properties of the additives would be impaired. without any damage,
The present invention was completed as a result of extensive research into additives that can increase adhesive strength, especially peel and impact strength. That is, the present invention relates to a 2-cyanoacrylate adhesive composition characterized by containing one or more compounds selected from nitrides or carbides of elements of group 1 or group 1 of the periodic table. Specific examples of the nitride or carbide contained in the 2-cyanoacrylate adhesive composition of the present invention include the following. Nitride: silicon nitride, aluminum nitride, boron nitride, titanium nitride, sialon (oxynitride containing silicon and aluminum) Carbide: silicon carbide, boron carbide, aluminum carbide, titanium carbide These nitrides or carbides have covalent bonds It is a compound with low polarity, low water absorption, and 2
- Probably due to its strong affinity with cyanoacrylates and metals, etc., when added to 2-cyanoacrylate adhesives, it improves adhesive strength, especially metals, without impairing the stability of the adhesive. It significantly improves the peel resistance and impact resistance in adhesion, making it an extremely excellent adhesive, which is an effect that could not have been predicted in the past. The content of nitride or carbide in the composition of the present invention is preferably 0.01 to 100 parts by weight, more preferably, based on 100 parts by weight of 2-cyanoacrylate.
It is 0.1 to 10 parts by weight. If the content exceeds 100 parts by weight, adhesive strength and curing speed will decrease.
If the content is less than 0.01 part by weight, the performance as an instant adhesive will be impaired, and if the content is less than 0.01 part by weight, the adhesive strength, especially the properties such as peel and impact strength, which are the features of the present invention, will be lost to the 2-cyanoacrylate adhesive. Not able to give enough. Since the nitride or carbide in the present invention is added to the 2-cyanoacrylate adhesive, it is preferable that the shape is granular, needle-like, powder-like, or whisker-like, and particularly preferable for the present invention are It is a compound of silicon nitride, boron nitride, silicon carbide, etc., and has a needle-like or whisker-like shape. The 2-cyanoacrylate in the present invention includes all common esters. Specifically, methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, sec-butyl, t
-butyl, amyl, n-hexyl, cyclohexyl, hebutyl, n-octyl, 2-ethylhexyl, dodecyl, allyl, brovagil, benzyl,
Examples include 2-cyanoacrylates such as phenyl, methyl cellosolve, ethyl cellosolve, 2-chloroethyl, hexafluoroisopropyl, trifluoroethyl, and 2-cyanoethyl. Typically, 2-cyanoacrylate adhesives include:
Stabilizers, thickeners, plasticizers, crosslinking agents, etc. are added, and these may be added in the same way in the present invention. Stabilizers include SO 2 , sulfonic acids,
Saltone, lactone, boron fluoride, hydroquinone hydroquinone monomethyl ether, catechol, pyrogallol, etc. are added in an amount of 1 to 1000 ppm. When a highly viscous adhesive is required, several percent of a polymer such as methyl methacrylate polymer, 2-cyanoacrylate polymer, or acrylic rubber is added as a thickener. Also, to improve the flexibility of the polymer, dioctyl phthalate,
Plasticizers such as sebacic acid esters and phosphoric acid esters may be added. In order to give the adhesively cured polymer a three-dimensional structure, a small amount of a polyfunctional vinyl monomer such as alkylene diacrylate, alkylene dimethacrylate, trimethylolpropane triacrylate, triallyl isocyanurate, etc. may be added. In such cases, an improvement in heat resistance is observed. The adhesive composition obtained in the present invention can be applied to iron, stainless steel, copper, brass, aluminum, zinc,
It is particularly effective for metals such as tin and ferrite.
It can also be used as an instant adhesive for other materials on which conventional 2-cyanoacrylate adhesives are used, such as plastic, wood, rubber, glass, ceramics, leather, paper, cloth, and thread. can. The adhesive of the present invention has improved adhesive strength, particularly peel resistance and impact resistance, compared to conventional 2-cyanoacrylate adhesives, and is superior to instant adhesives. It has been desired for a long time because it has the performance of a structural adhesive. Because of these excellent features, the adhesive composition of the present invention can be used not only for the fields of use of conventional 2-cyanoacrylate adhesives, but also for locking screws, screws, bolts and nuts, bearings, motor shafts, It can also be used for fixing fittings such as gears and axles, sealing gaskets, flanges, and pipe joints, and potting. The present invention will be specifically described below with reference to Examples and Comparative Examples. Examples 1 to 12 and Comparative Examples To 100 parts by weight of ethyl-2-cyanoacrylate containing 500 ppm of hydroquinone and 30 ppm of SO2 ,
0.1 to 10 parts by weight of nitrides or carbides shown in Table 1 were added, and the mixture was shaken at room temperature for 1 hour. The adhesive composition thus obtained was subjected to the following adhesion test. Further, as a comparative example, a similar test was conducted on a product containing no nitride or carbide. The tensile shear strength was measured according to JIS K 6850 using iron as a test piece. The impact strength was measured according to JIS K 6855 using iron as a test piece. Measurement of T-type peel strength is based on JIS K
6854, using a 200 μm thick aluminum plate as a test piece. In addition, the setting time using iron was within 10 seconds in both the example and the comparative example.
The storage stability and dispersibility were examined by shaking the product after it was left indoors for one month. The results are shown in Table 1. 【table】
