The present invention relates to a sodium silicate adhesive, and more particularly to a sodium silicate adhesive having a buffering effect capable of absorbing strain caused by a difference in thermal expansion when a metal member and a ceramic member are bonded together. In particular, after inserting a metal rod into the inside of a porcelain cylinder with a slight gap, filling the gap with a sodium silicate adhesive and drying it, it will be bonded.
When exposed to temperatures of °C, there was a problem of porcelain cracking because the coefficient of thermal expansion of the metal rod is much larger than that of the porcelain cylinder. On the other hand, by adding lard oil or silicone oil to the adhesive, it was possible to provide a buffering effect and prevent porcelain cracking, but lard oil could not be mixed uniformly with sodium silicate, and silicone oil It was difficult to make drastic changes. The present invention is an improvement on these, and is No. 1 or No. 2.
No. 1 sodium silicate (liquid SiO 2 :Na 2 O specified in JIS standards is 35-38%: 17-19% for No. 1)
n of Na 2 O・nSiO 2 is 2.1 to 2.2, and 34 in No. 2
~36%: n of Na2O・nSiO2 is 2.4-2.5 at 14-15%
) 49.95~47.5% by weight and inorganic powder 49.95~
This product provides a sodium silicate adhesive consisting of 47.5% by weight and the balance being a surfactant, which forms many extremely fine bubbles in the sodium silicate adhesive after heat treatment, giving it elasticity. This absorbs distortion caused by the difference in thermal expansion between porcelain and metal, improves the wettability between sodium silicate and inorganic powder, porcelain and metal members, and increases adhesive strength. There are cationic, anionic, and nonionic types of surfactants, and any surfactant can be used without being specified in the present invention, but the anionic type is stable in alkaline sodium silicate. showing the characteristics of
The nonionic type exhibits stable properties even when used in alkaline and acidic conditions. The anionic surfactant is alkyl sulfate ester soda (trade name: Monogen T-
423, manufactured by Daiichi Kogyo Seiyaku, hereinafter referred to as Monogen T-423), and nonionic surfactants include polyethylene glycol nonyl phenol ether (trade name Neugen EA-140, manufactured by Daiichi Kogyo Seiyaku hereinafter referred to as Monogen T-423). uniformly filled out in Neugen EA-140),
The cationic surfactant is polyacrylamide special polymer (trade name Hiset C-721, manufactured by Daiichi Kogyo Seiyaku, hereafter referred to as Hiset C-721), and it is the result of repeated tests to create a foaming state. It was found that these three types showed the best effect. Example 1 Anionic surfactant Monogen T-423 was simultaneously mixed with calcined clay powder containing 50% particles of 5μ or less and liquid No. 1 sodium silicate in the proportions shown in Table 1, and kneaded for 1 hour. The viscosity is optimal for adhesion.
Add water to make it 350±50 poise. Next, the above-mentioned mixture was applied to the inner hole 4 of a porcelain cylinder 1 having a shape as shown in Fig. 1, ie, an outer diameter of 5 mm, an inner diameter of 2.8 mm, and a length of 50 mm, for a heating test and a cement blowout investigation. 60mm nickel wire 2 length
Apply adhesive 3 prepared above to 50 mm and insert and bond. After naturally drying the bonded sample at room temperature for 10 hours or more, the temperature was increased at a rate of 20℃/Hr, and the temperature was raised to 400℃.
Heat drying was performed for 30 minutes. For each of the 10,000 samples completed above, the cement blowout from the porcelain end face 4a, which is the contact area between the porcelain and the metal fittings, was visually inspected, and one end of each of the 100 samples was heated to 800°C using a Bunsen burner. The number of broken pieces of the porcelain body was determined by repeating the test 600 times under conditions of heating for 5 hours and cooling for 5 minutes, and the results are shown in Table 1 as a percentage.

る。[Table] From Table 1, the occurrence rate of porcelain cracking in the burner heating test of the adhesive containing Monogen T-423 of the present invention was 1% in sample No. 1 with 0.1% added, and 1.0% to 5.0%. There was no occurrence in Samples No. 2 to No. 9 of additives containing surfactants, and 18% occurred in Sample No. 11, a comparative product with no surfactant added. Clearly, the effect of addition was significant, and cement blowout Samples containing 0.1% to 3.0% of the invention product
Samples No. 1 to No. 6 had an incidence of 0.01% or less, and Samples No. 7 to No. 9, in which 3.5% to 5.0% had been added, had an incidence of 0%. As a comparison, sample No. 11 to which no surfactant was added had an occurrence rate of 0.2%, and the product of the present invention significantly reduced the occurrence rate. In addition, sample No. 10 with a content of 6.0% as a comparative product exceeding 5.0% of Monogen T-423 of the present invention had no incidence of porcelain cracking or cement blowout in the burner heating test; Amount 5.0%
If the temperature exceeds that level, the kneaded product will generate more bubbles and the workability will deteriorate. In addition, the upper limit of the content in the present invention was set at 5.0% because there are extremely many bubbles after drying, which deteriorates properties such as adhesive strength and airtightness. Example 2 Non-ionic surfactant Neugen EA-140 was added to liquid No. 2 sodium silicate and stirred uniformly and evenly, and calcined clay powder containing 50% of particles of 5μ or less was added thereto. Knead for 30 minutes and add water to adjust the viscosity to 350±50 poise, the optimum viscosity for adhesion. The above formulations are in weight proportions giving a total amount of 100 as shown in Table 2. Next, the above-mentioned mixture was prepared in the same shape and method as in Example 1 for heating tests and cement blowout investigations, and dried. The completed samples were tested using the same test method as in Example 1, and the percentages are shown in Table 2. Table 2 shows the occurrence rate of porcelain cracks and cement blow-out in the burner heating test of the adhesive of the present invention containing Noogen EA-140 of Example 1.
There is almost no difference from the adhesive containing 423, and it is much better than a comparative product that does not contain surfactant.

Add water to make it 350±50 poise. In this case, the surface of the preparation tends to harden and storage is difficult, so it is necessary to prepare the preparation immediately before use. Next, the above-mentioned mixture was manufactured in the same shape and method as in Examples 1 and 2 for use in heating tests and cement blowout investigations, and was dried. In addition, the completed sample was tested using the same test method as in Examples 1 and 2, and the percentage was 3.
Shown in the table. In Table 3, the incidence of porcelain cracking in the burner heating test of the adhesive of the present invention containing Hiset C-721 was as follows: Sample No. 1 with 0.1% added, Sample No. 2B and No. 2 with 1.0% and 2.0% added, respectively. .3B is Example 1
Monogen T-423 of Example 2 and Neugen EA- of Example 2
1% more than those containing 140.
Also, the incidence of cement blowout was for the sample with 0.1% added.
Sample No.2B with No.1B added with 0.03% and 1.0%
Although it is 0.02%, which is a slight increase from the samples of Example 1 and 2, it is better than the comparative product without the addition of surfactant, and there is no problem in use.

Neugen EA-140 was mixed and stirred evenly and evenly, and then the calcined clay powder was mixed and kneaded, but the samples obtained by both mixing methods were similar to Examples 1 and 2, but The latter mixing method adopted in Example 2 allows stirring in a shorter time and is better. In addition, No. 1 sodium silicate was used in Examples 1 and 3, and No. 2 sodium silicate was used in Example 2, but judging from the test results of the assembled parts, there was no abnormality in both No. 1 and No. 2 sodium silicate. There is no problem in using it. Observation of the fractured surface of the above example using a magnifying glass reveals that the surfactant according to the present invention is well dispersed in sodium silicate, creates a uniform foamed state, and forms an adhesive with elasticity even after drying. It is a widely used and effective additive for bonding and fixing spark plug insulators and central shafts, with almost no porcelain cracking caused by cement blowing and heating. In addition, although calcined clay powder is used as an example of the inorganic powder, for example, alumina, nitride, carbide, or metal powder may be substituted or used in combination, and higher adhesive strength or airtightness is required. In some cases, it is used in place of or in combination with frits such as soda glass, borosilicate glass, lead glass powder, etc.
