This invention relates to a sodium silicate adhesive mixed with a curing accelerator. Conventionally, sodium silicate (Na 2 SiF 6 ) has been generally known as a curing accelerator for sodium silicate, but this has had the problem of causing pollution because the wastewater contains F - ions and the like. In addition, especially when a sodium silicate adhesive with no hardening accelerator added is used as a heat-resistant air sealant to bond porcelain and metal parts, fine cracks and foam-like blowouts may occur during the drying process, reducing the bond strength. ,airtightness,
There was a problem that heat resistance, mechanical impact strength, etc. decreased. The present invention was made for the purpose of improving the above-mentioned drawbacks, and it combines metal oxide powder and No. 1 or No. 2 sodium silicate (liquid SiO 2 :Na 2 O specified in JIS standards). 36-38% for No. 1: 17-18%
So, n of Na 2 O・nSiO 2 is 2.0, and in No. 2 it is 34~
36%: A mixture of 99 to 90% by weight (hereinafter omitted by weight) of an equal amount of 14 to 15% Na 2 O. The present invention provides a sodium silicate adhesive characterized in that the frit is made of one or more of soda glass powder, borosilicate glass powder, and lead glass powder. The adhesive made of sodium silicate added as a curing accelerator is cured by dehydration, and the moisture on the surface first decreases, forming gel-like water glass. When 1 to 10% of one or more of soda glass powder, borosilicate glass powder, and lead glass powder is contained as a substitute for the sodium silicide powder, gelation progresses from the inside, resulting in a dense foam with less blow-out. The frit has good chemical affinity with sodium silicate, so it has a strong adhesive force and is resistant to mechanical shock. To explain an example below, calcined clay powder containing 50% of particles of 5μ or less, liquid No. 1 sodium silicate, soda glass powder of 105μ or less (passed through 150 meshes), borosilicate glass powder, and lead glass powder. One or more of them are blended in a weight ratio giving a total amount of 100 as shown in Table 1, kneaded for 30 minutes, and water is added so that the kneading viscosity becomes the optimum viscosity of 350±50 poise. Prepare. Next, the above-mentioned mixture was placed in a porcelain cylinder 1 having a diameter of 8.5 mm and a length of 20 mm, as shown in Fig. Cylindrical part 2a with a length of 20 mm
The 2b portion of the stepped cylindrical iron core 2 consisting of the cylindrical portion 2b with a diameter of 5.2 mm and a length of 10 mm is coated with the above adjusted adhesive 3 to a length of 10 mm and inserted and bonded. After drying the bonded sample naturally for more than 10 hours in a room at 25℃/
The temperature was increased at a rate of 130° C. for 5 hours and dried by heating. Boundary line 4 between the porcelain and metal fittings of the sample completed above
We visually inspected 1000 pieces of cement blowing out of each sample, fixed the porcelain part of each of the 10 samples, applied torque to the iron core, and measured the torque that would cause the adhesive surface to break. The average value is shown in kg/cm and entered in Table 1 along with the cement blowout results.
It is shown in Figure 1 for clarity. In the figure, the solid line indicates the adhesive force in kg·cm, and the dotted line indicates the percentage of the blown product. Figure 1 shows that the adhesive strength of the adhesive containing the frit of the present invention ranges from a minimum of 96 to a maximum of 122 kg cm, and this value is comparable to that of the adhesive using sodium silicate as a hardening agent, and the adhesive strength of the adhesive without a hardening agent. The adhesive strength is 85
Kg·cm, which clearly had a significant effect, and the effect of adding the curing agent of the present invention on the cement blowout rate was reduced to 1/8 or less in the worst case compared to a comparative product without additives.

る。[Table] Furthermore, when the frit content of the present invention exceeds 10%, the adhesive strength of the adhesive containing 12% of one of soda glass powder, borosilicate glass powder, and lead glass powder is 93,
94, 94 Kg·cm, which clearly shows a tendency to decrease compared to 99, 104, and 108 Kg·cm, which is the adhesive force of the adhesive containing 10% of the upper limit of the present invention. Furthermore, if the content exceeds 10%, the amount of water added will increase to meet the viscosity regulation of 350 poise, and the curing time will become faster. As a result, the upper limit of the frit content in the present invention was set at 10%, since this would impede workability during constant continuous use. The difference in adhesive strength between the hardening agents of the present invention, soda glass powder, borosilicate glass powder, and lead glass powder, is that when each hardening agent contains 4%, the soda glass powder is 108 kg cm, the borosilicate glass powder is 108 kg cm. is 118Kg・
cm, lead glass powder is 122Kg・cm, and
When containing 10%, soda glass powder is 99Kg・cm, borosilicate glass powder is 104Kg・cm, and lead glass powder is 108Kg・cm. Lead glass powder, borosilicate glass powder, and soda glass powder are superior in order. There was a difference. The adhesion strength of the adhesive was examined for the hardening agent of the present invention, which is a mixture of two or three of the following: soda glass powder, borosilicate glass powder, and lead glass powder. powder 3%
Adhesive containing 3% of borosilicate glass powder and
Two types of adhesives No. 10 and No. 11 containing 3% borosilicate glass powder and 3% lead glass powder had weights of 112 and 117 kg・cm, respectively, and contained 6% borosilicate glass powder alone. Judging from the adhesive strength of the adhesive of 108 kg cm, the difference between the one containing one kind and the one containing two kinds is small, and the one containing three kinds, 8%, that is, 2% soda glass powder and 3% borosilicate glass powder. % and adhesive No. 12 containing 3% lead glass powder, the adhesive strength of the adhesive was 105 kg cm, which is the adhesive strength of 6 and 10% adhesives containing single ingredients in Table 1.
Compared to 108 and 104 Kg.cm, it can be judged that the adhesive strength of the adhesive containing two or three types of frits is not much different from that of the adhesive containing one type of frit. As mentioned above, the addition of one or more of soda glass powder, borosilicate glass powder, and lead glass powder as a curing agent to the sodium silicate adhesive according to the present invention is F as a curing accelerator that converts into sodium silicate. Since it does not contain ions, it does not cause pollution, has no microscopic cracks or foam-like blowouts, has a high adhesive effect, and can be used as an additive with excellent heat resistance, airtightness, and mechanical impact resistance. It is an effective additive with a wide range of uses, such as fixing the electrodes of piezoelectric ignition devices that require special characteristics, fixing sensor elements, and adhesive fixing the spark plug insulator and central shaft. In the above embodiments, calcined clay powder was selected as an example of the metal oxide powder, but the present invention is not limited to this, and porcelain powder, refractory powder, and natural stone powder can equally be used. Further, although soda glass powder, borosilicate glass powder, and lead glass powder were used as the frit, any other glass powder can be equally used in place of soda glass. Furthermore, although liquid No. 1 sodium silicate was used as the sodium silicate, it is also possible to use No. 2 sodium silicate in the same manner.
