- An object of the present invention is to provide a method of manufacturing a gasket capable of improving adhesion.
- the present inventors have found that the degreasing effect by conventional alkali treatment such as sodium hydroxide alone is not sufficient to improve the adhesion of the metal surface. Furthermore, they have found that the etching effect (anchor effect) affects the adhesion, and found that the force and the etching effect (anchor effect) are exerted by a carboxylate, leading to the present invention.

- FIG. 11 A sectional view taken along the line xii-xii of FIG. Explanation of sign
- the alkali treatment liquid used in the method for producing a gasket of the present invention contains the following (A), (B) and (C).
- the hydrophobic groups of (A) and (B) adhere to the oil on the surface of the stainless steel plate, and the oil is pulled off.
- a plurality of OH groups are formed so as to cover the entire surface in a state of being singly bonded to the surface metal, and the wettability is improved (3).
- the OH group achieves adhesion between the stainless steel plate and the rubber by, for example, an intermolecular force with a silicone rubber or a hydrogen bond.
- the etching process (2B) is due to the action of (C) carboxylate. COO in carboxylate
- the H group removes the oxide film on the surface of the stainless steel plate. As a result, the hydrophilicity of the stainless steel sheet surface is improved, and the wettability is also improved (3).
- the carboxylate not only removes the oxide film on the surface of the stainless steel plate, but also forms irregularities on the surface. That is, this is the etching effect. If the etching is appropriate, the anchor effect with rubber is exhibited and the adhesiveness is improved (4).
- FIG. 2 shows the experimental results showing the relationship between the degreasing time and the wettability
- FIG. 3 shows the experimental results showing the relationship between the etching time and the wettability.
- curve A shows how the organic film decreases with degreasing time.
- Curve B shows the state in which SiO increases with the degreasing time. Since the wettability decreases as the amount of SiO increases, it is not considered that there is an acceptable range of wettability which can exert the effects of the present invention, the present inventors think that the good region of the degreasing time in the drawing is X. We found it to be desirable in terms of tackiness.
- curve C shows the state in which the wettability changes with the etching time. It was found that the cause of the change in the wettability is that as the etching time is increased, the irregularities on the surface of the stainless steel plate are combined and the tackiness is deteriorated.
- the inventors of the present invention have found that the allowable range of wettability which can exert the effects of the present invention is preferable in terms of improving the adhesion, in the good region Y of the etching time in the drawing.

- the core 2 after alkali treatment is not shown.
- the rubber is filled with the uncured rubber 1 in the mold.
- the rubber 1 is coated and bonded so as to sandwich the core 2 from the outer periphery of the core 2 by vulcanizing the rubber 1 according to a conventional method. At this time, no adhesive is used to bond the core 2 to the rubber 1.
- the core material 2 adheres to the core material 2 by alkali treatment of both degreasing and etching, and the core material 2 and the rubber 1 are integrated without peeling.
- the core material 2 and the rubber 1 need to be closely integrated by providing the core material 2 with a conventional through hole and providing the rubber 1 with a connecting part penetrating the through hole. Although it is possible, it does not exclude the structure which provides a through-hole and a connection part conventionally.
- a stainless steel plate (SUS 304) having a thickness of 1 mm was pressed to form an annular core as shown in FIG.
- the treatment liquid shown in Table 1 was added to water at a compounding concentration shown in Table 1 to prepare an alkali treatment liquid.
- Al-Nion E (made by Ruken Kogyo Co., Ltd.): Alkaline treatment solution containing agent C
- Al-Nion G (made by Ruken Kogyo Co., Ltd.): Alkaline treatment solution containing agent C
- the core material was immersed in the above-mentioned alkali treatment liquid (temperature 55 ° C.) for the time shown in Table 1, treated with alkali, pulled up, washed with water and dried.
- silicone rubber in an unvulcanized state (“S256” manufactured by NOK) is filled in the mold and the core material is inserted into the silicone rubber.
- silicone rubber was vulcanized to prepare a gasket in which the core material and the rubber were integrated.
- the composition was coated with a cotton swab and the wettability was measured within 2 to 5 seconds after the application (JIS K6768-1995). If it is 54 dyn / cm or more, it can be evaluated as good wettability. The results are shown in Table 1.
- the rubber and the core material are in close contact with each other and do not peel off even if compressed!
- Example 1 the results of the evaluation in which alkali treatment was similarly evaluated instead of the formulations shown in Table 1 are shown in Table 1.
- the wettability is excellent in the plasma treatment (Comparative Example 3) or the corona treatment (Comparative Example 4), but it is understood that the adhesion is inferior.
- Example 14 it is found that both the wettability and the adhesive strength are excellent.
- Example 1 the alkali treatment time was changed, and the wettability and the tackiness were measured, and the results are shown in FIGS. 7 and 8.
- the adhesive strength was 13 N or more, and the rubber and the core material were in close contact and did not peel even if compressed.
