、精度が悪いという問題がある。(Prior art) In order to apply a glass coating to the surface of a base material made of metal, ceramics, etc., a mixture of glass powder and a vehicle is applied onto the surface of the base material by means such as screen printing, transfer spraying, etc. , firing is the most common method. However, the screen printing method has problems in that uniform printing may not be possible depending on the shape of the base material, and that equipment costs are high. Although the transfer method requires low equipment costs, it has the problem that the film is thin and it is difficult to achieve precision. Furthermore, although the spray method can be applied to a wide area, it has the problem of large variations in film thickness and poor accuracy.

ある。On the other hand, as a method for glass-bonding other members to the surface of a base material, in addition to the screen printing method described above, a method is known in which a thin glass plate called a preform is placed on the surface of the base material and fired. However, this method reduces the film thickness to 200 μm.

It is an object of the present invention to provide a glass bonding method that allows members of various shapes to be easily glass bonded using a glass layer of any thickness using this glass coating method.

決される。(Means for Solving the Problems) The above problems are achieved by using a sheet of kneaded fine glass powder and a resin binder, using an adhesive that is readily soluble in solvents when the resin binder is water-soluble, and is readily soluble in a solvent, the glass coating method is characterized by adhering to the surface of the substrate using a water-soluble adhesive and baking it in a furnace to form a glass layer on the surface of the substrate. resolved. Moreover, the above-mentioned problem is solved by a glass bonding method characterized in that another member is bonded to the surface of a base material using the glass layer thus formed.
このように本発明においてはガラスの微粉末と樹脂バイ
ンダとを混練したシートが用いられる。As described above, in the present invention, a sheet obtained by kneading fine glass powder and a resin binder is used.
ガラスの微粉末としては従来からガラス接合用等に用い

に応じて使用され、目的によっては結晶化ガラスの微粉
末を用いることもできる。As the fine powder of glass, low melting point glasses conventionally used for glass bonding, frinoto for enamel, etc. are used depending on the purpose, and fine powder of crystallized glass can also be used depending on the purpose.

加してもよい。The resin binder is used to form the entire sheet into a sheet, and can be made of water-soluble resins such as polyvinyl alcohol, carboxymethylcellulose, and methylcellulose, and organic resins such as polyvinyl butyral, styrene resin emulsion, acrylic resin emulsion, and butadiene resin emulsion. A readily solvent soluble resin is used. In addition, a small amount of plasticizer such as diptyl phthalate or diethylene glycol may be added.
シート中におけるガラスの微粉末の混合比は２０〜９０
重量％が適当である。これはガラスの混合比が２０％未

不足してシート化が困難となるためである。またシート
全体の厚さは５０〜４００μｍ程度が好ましい。The mixing ratio of fine glass powder in the sheet is 20 to 90
Weight % is appropriate. This is because if the glass mixing ratio is less than 20%, it will not be possible to obtain a uniform glass coating or sufficient bonding strength, whereas if it exceeds 90%, there will be a relative lack of resin binder, making it difficult to form a sheet. . Further, the thickness of the entire sheet is preferably about 50 to 400 μm.

ることを防止するためである。In the first invention, such a sheet is cut to fit the intended glass coating area, and then adhered to the surface of the base material and fired. Also in the second aspect of the invention, the sheet is cut to fit the intended glass bonding area, adhered between the base material and another member to be bonded thereto, and fired. For this purpose, if the resin binder in the sheet is water-soluble, use an adhesive that is easily soluble in organic solvents, or if the resin binder in the sheet is easily soluble in organic solvents, use a water-soluble adhesive. A sterile adhesive shall be used. This is to prevent the adhesive from damaging the sheet.

好ましい。これはシートと基材との間に隙間を設けるこ

るために基材上から移動してしまうこととなる。Further, in the present invention, it is preferable that the entire surface of the sheet is not bonded to the base material, but rather that several points are bonded in a dotted or mesh pattern. This is because by creating a gap between the sheet and the base material, the gas generated by thermal decomposition of the adhesive during firing can escape from the bottom surface of the sheet.If the entire surface is bonded, the gas will be released inside the sheet. There is a risk of foaming and not forming a uniform glass coating layer or glass bonding layer. Also, if there is no adhesion at all, the sheet will be so thin that it will move off the base material.
このようにシートを基材の表面に点状または網目状に接
着したものを焼成すれば、樹脂バインダが熱分解して飛

材の表面に均一な膜厚のガラスコーティング層が形成さ
れる。また第２の発明によれば、このシートが溶融して
生じたガラス層を利用して基材の表面に他の部材を気密
にガラス接合することができる。When the sheet is bonded to the surface of the base material in dots or meshes and then fired, the resin binder thermally decomposes and scatters, and the fine glass powder in the sheet melts and attaches to the surface of the base material. A glass coating layer with a uniform thickness is formed. Further, according to the second invention, other members can be airtightly glass-bonded to the surface of the base material by using the glass layer produced by melting this sheet.

こともない。Is the thickness of the sheet used in the present invention the same as that of conventional sheets? Since it can be manufactured much thinner and more uniformly than in the case of renovation, it is possible to apply a glass coating of uniform thickness to the surface of the base material. Moreover, since this sheet can be cut into any size and used, it is possible to apply glass coating with high precision to the surface of a base material of any shape. Moreover, according to the present invention, there is no fear that the sheet will be melted by the adhesive, and gas generated by thermal decomposition of the adhesive will not cause foaming of the glass coating surface or the glass bonding surface.
