Description of the Related Art Conventionally, as the above-mentioned heat insulating member with packing, there is one in which an asbestos joint sheet is attached to the surface of a phenol resin molded product. It is manufactured through many steps of mixing rubber and base material (asbestos), forming it into a sheet with a calendar roll, punching it into the specified product shape, and attaching it to the surface of the heat insulating member with an adhesive. It was done. Such a heat insulating member with packing fulfills the functions of heat insulation and airtightness, for example, by being interposed between members constituting a carburettor of an automobile and tightened and fixed by bolts. Asbestos is not used due to safety and hygiene regulations, and a joint sheet using inorganic fibers other than asbestos such as glass or aromatic polyamide fibers instead of asbestos is being used as a base material.

下で、パッキング付き断熱部材の気密性向上の要求が一
層強くなっている。By the way, in an automobile engine, reduction in rigidity and variation in expansion and contraction have become large due to weight reduction (thinning, material change to aluminum). Further, due to the miniaturization (miniaturization and reduction of parts), the size of the bolts for mounting and tightening the heat insulating member has become smaller and the number of bolts has become smaller. Furthermore, due to higher output (turbocharger), the temperature is high. Under such circumstances, there is an increasing demand for improving the airtightness of the heat insulating member with packing.

トルク）。However, the above-mentioned heat insulating member with packing to which the joint sheet is attached cannot sufficiently meet the above requirements. That is, when the heat insulating member with packing interposed between the mating members is tightened with bolts, the packing reduces the thickness by the pressure and adheres to the mating member, but in order to reduce the thickness of the packing, the tightening torque is reduced. It must be large enough (usually a tightening torque of 150 to 200 kg · cm with a bolt of 8 mm diameter).

でなくなっている。However, as described above, if the number of tightening bolts is small and the pitch between the bolts is long, or the rigidity of the mating member for interposing the heat insulating member is low, the thickness of the packing at the position away from the tightening bolts. Is not reduced, the mating member is deformed (curved), and the adhesiveness with the packing deteriorates. Figure 5
This state is shown, and the packing layers 2 and 2 '(joint sheets) attached to both surfaces of the heat insulating member 1 are
Although the thickness is reduced near the tightening bolt 3,
The mating member 4 is deformed at the center between the bolts separated from the tightening bolt 3. Therefore, the surface pressure on the packing is also small in the center between the tightening bolts and is not uniform.

In this case, adhesion can be obtained even with a small tightening torque that does not deform the mating member. However, the difference between the internal pressure and the external pressure is 3Kg
If it exceeds / cm 2 , airtightness cannot be maintained. In addition, the tightening torque during use is significantly reduced.

る。The manufacturing method according to the present invention comprises:
It is characterized in that rubber is applied to the surface of the heat insulating member and heat treatment is performed to integrally form a packing layer on the surface of the heat insulating member. In this heat insulating member with packing, it is desirable that the thickness of the packing layer in the portion away from the position where the bolt is tightened is increased. In addition, it is also desirable to apply a second coating on the first coating layer of rubber to increase the thickness of the packing layer around the liquid or gas circulation port provided in the heat insulating member. is there. The means of applying rubber is
Screen printing is preferred. The surface of the packing layer may be provided with fine irregularities in a grid pattern. When a phenol resin molded product is used as the heat insulating member, a silicone oil-based primer is applied to the surface of the heat insulating member before applying the rubber. Blending the fluororesin powder with the rubber applied to the surface of the heat insulating member is preferable for other purposes.

現象を抑制することができる。In the method according to the present invention, since the heat insulating member is coated with rubber to form the packing layer, a thin packing layer which cannot be realized by the conventional method of attaching a joint sheet or a single rubber piece to the heat insulating member is formed. Is possible with a simple process. Since such a thin packing layer has a small amount of deformation in the thickness direction even when compressed, there is little difference in thickness after tightening between the part located near the tightening bolt and the part distant from the tightening bolt. .. Therefore, even if it is used by interposing it between members having low rigidity, it is possible to suppress the phenomenon that the member having low rigidity is deformed without compressing the packing layer.

材に焼き付くのを抑制することができる。However, in consideration of some deformation of the member having low rigidity, the airtightness can be further improved by slightly increasing the thickness of the packing layer in the portion away from the tightening position. Similarly, the airtightness can be enhanced by increasing the thickness of the packing layer around the liquid or gas passage provided in the heat insulating member. Thus, the partial thickness change of the packing layer can be easily achieved only by the method of forming the packing layer by coating. If the silicone rubber is applied by screen printing, the thickness can be adjusted easily, and if a fine grid-like unevenness is formed on the applied surface by using the screen mesh, the unevenness buffers the adhesiveness. It is possible to improve the airtightness by repairing the scratches on the surface of the mating member.
When using a phenol resin molded product as a heat insulating member,
The residual amines do not easily cure the rubber due to heating, but by applying a silicone oil-based primer to the surface of the heat insulating member beforehand, the adhesion of the formed packing layer to the heat insulating member will be sufficient. Can be big. By blending the fluororesin powder in the rubber applied to the surface of the heat insulating member, it is possible to prevent the packing layer from sticking to the mating member during use at high temperature and high pressure due to the releasing property of the fluororesin.

In particular, when the fluororesin powder is blended in rubber in an amount of 5% by weight or more, the effect of preventing seizure becomes remarkable. Considering the effect of maintaining the airtightness of the packing layer, the upper limit of the blending amount of the fluororesin powder is preferably 20% by weight.

Even if the tightening torque is small, the airtightness is good,
Since the decrease in tightening torque is small, stable airtightness can be maintained for a long period of time. If the thickness of the packing layer is partially changed or if the surface of the packing layer is made finely uneven, the airtightness is further improved although the tightening torque retention rate is slightly lowered.

ている。Further, in a high temperature atmosphere, the difference in thermal expansion between the heat insulating member and the mating member interposing the heat insulating member becomes large and the stress easily breaks the heat insulating member. However, in the heat insulating member according to the present invention, a thin packing is used. The layer absorbs the stress and deforms to prevent cracking of the heat insulating member. Moreover, since the deformation is not so large as in the case where the conventional thick rubber sheet is attached to the heat insulating member, the airtightness is sufficiently maintained.
