摘要： PURPOSE:To enable a liquid gasket to satisfactorily follow a shift of jointed surfaces or an opening, by containing 5 to 50vol% of granular filler having particles of a diameter of about 0.11mm. and is hard to be broken against compression, into a liquid gasket. CONSTITUTION:Granular filler such as, for example, glass particles (glass beads), iron particles or plastic particles (plastic powder) which is insuolble to organic solvent such as polypropylene, polyethylene or the like, is contained at 5 to 50vol% in a, for example, viscoelastic liquid gasket. The rate of the content of the granular material depends on the particle size thereof. For example, in order to maintain 0.01mm. of self-clearance, it is necessary to contain 5% of granular filler having particles of at least 0.1mm. diameter. If the content of granular filler is less than 5vol%, the layer of the liquid gasket is blown out by fluid pressure so that leak is brought about, and if the content is more than 50vol%, the gasket layer itself is caused to deteriorate which is not preferable.

摘要： PURPOSE:To obtain stability of long period and high reliability to grooved type flanges of various shapes, by casting liquid sealing material in the groove of the grooved type flange into which an annular bank of one of joint surfaces is fitted, and pressingly mating both joint surfaces after the sealing material is cured. CONSTITUTION:A circular bank 3 on one of flanges is abutted to a sealing material 7 which is made resilient in a groove 5, and then the opposite surfaces of both flanges are pressingly contacted together by fastening a bolt 6 so that sealing is obtained. Since the sealing material 7 is held in a thickness larger than the clearance between the top of the bank 3 and the bottom of the groove 5, the sealing material 7 is partly built up into the gaps each defined between one of the lateral walls of the circular bank 3 and the associated lateral wall of the groove 5 when both flanges are mated at their opposed contacting surfaces 8 in the condition of metal touch. Thereby, the surface pressure exerted to the outer surface of the resilient material 7 given with resiliency, is relaxed so that it is not subjected directly to rigid strain due to flange vibration, thereby liquid leakage due to pumping action may be prevented.

摘要： PURPOSE:The titled sealer that contains a vinyl chloride resin or its copolymer as a base resin, a temperature-sensitive thixotropic agent and thermally expandable particles, thus showing good inflowing properties and sealing ability, because it has specific flowing properties and thermal expansion. CONSTITUTION:(A) A vinyl chloride or its copolymer is used as a base resin, which is mixed with (B) (i) a temperature-sensitive thixotropic agent of hydrogenated linseed or castor oil and (ii) thermally expandable particles to give the objective thermally setting type sealer. The sealer has horizontal and vertical flowability of less than 10mm. at room temperature for 30min and more than 10mm. at 110 deg.C for 30min. Further, the expansion of the sealer is less than 50% at 110 deg.C for 10min and more than 50% at 140 deg.C for 30min. The flowability of the sealer is preferably more than 50mm. in the horizontal direction and more than 100mm. in the vertical direction at 110 deg.C for 30min and the thermal expansion is preferably more than 80% at 140 deg.C for 30min.

摘要： PURPOSE:To prevent leakage of oil and improve the incorporating property of a pan by a method wherein liquid gasket is coated on the protruded arcic surface of a member at the side of an engine and the oil pan, coated with the liquid gasket on the mounting surface thereof, is pressed against and fixed to the engine side member when the liquid gasket, coated on the engine side member, is dried or half dried. CONSTITUTION:The semi-arcic protruded surface of an oil seal retainer 6 of the engine side member, which is positioned so as to oppose to the recessed arciform surface 4 of the oil pan 2, is the mounting surface for the oil pan and the engine side mounting surface except said mounting surface is flat. A recess 10 is formed on the recessed semi-arciform surface 4 of the oil pan 2 along the whole length thereof while a recessed groove 11 is indented at the center of axial direction of the semi-arciform protruded mounting surface 7 of the oil seal retainer 6 along the whole periphery of circumferential direction of the semi-arciform protruded mounting surface 7 and a part of the flat mounting surface. The liquid gasket is coated on the recessed groove 11 and is half dried or dried, thereafter, the liquid gasket is coated on the whole periphery of the mounting surface 3 of the oil pan 2 and, then, both of them are pressed and fixed.

摘要： PURPOSE:To provide a sealer particularly suitable for cars, which does not exhibit the flowability at normal temperatures and therefore may be handled with ease but may flow under the influence of heat and exhibit a high sealing effect after the hardening, by incorporating a thermosensitive thixotropic agent into a vinyl chloride resin. CONSTITUTION:10-50wt% vinyl chloride or vinyl chloride copolymer resin, 0.1-10wt% thermosensitive thixotropic agent (e.g. hydrogenated linseed oil, hydrogenated castor oil, or a low temperature melting type PE), 20-60wt% filler (e.g. calcium carbonate, or talk), 5-50wt% plasticizer (e.g. a phthalate ester) and 0.1-10wt% tackifier are kneaded to obtain the titled sealer that has horizontal and vertical flowabilities of not greater than 10mm. at normal temperatures for 30min and a horizontal flowability of 10-200mm. and a vertical flowability of 10-400mm. at 140 deg.C.

摘要： PURPOSE:To make plural draft holes stoppable with a single grommet, by installing a ribbed part consisting of plural members of ribs in position around the grommet. CONSTITUTION:A head part 5 at the push-in side is made to be thick, while a ribbed part 6 is installed in a shaft part 7 beneath the head part at specified intervals. With this constitution, even if a bore diameter and plate thickness differ in size, the ribbed part 6 can extensively meet requirements. That is to say, plural draft holes can be stopped up with a single grommet.

摘要： PURPOSE:To maintain a liquid gasket to the prescribed thickness by coating a mating surface of one member with the liquid gasket, dropping spherical granules on the liquid gasket at suitable intervals, and thereafter connecting the other member with that mating surface. CONSTITUTION:When mating surfaces of two members are sealed by a liquid gasket, the mating surface of one member 2 to be sealed is coated with the liquid gasket 3 supplied from a coating nozzle 4, and granules 6 are dropped on the liquid gasket 3 at suitable intervals from an extrusion nozzle 5 integral with the coating nozzle 4. Accordinly, the liquid gasket 3 is maintained to the prescribed thickness and the noise caused by the contact of the two members is prevented, as well as the sealing ability therebetween is improved. Further, the coating operation of the liquid gasket 3 is smoothed by supplying the liquid gasket 3 and the granules 6 separately as described above.
