い。The body of an automobile is made of steel plate coated with electrodeposition coating. A body sealer is applied or filled to the joints and seams of the steel plates to seal the gaps, thereby maintaining airtightness and improving the rust prevention properties of the steel plates. A solvent-based intermediate coat or top coat is applied over the body sealer. These body sealers, intermediate coats, and top coats are heat cured after each application or in combination with multiple layers. To apply the body sealer, a coating gun that discharges the body sealer from the tip of the nozzle is used. Since the discharge opening of the nozzle of this coating gun is generally circular, the surface of the applied body sealer becomes a curved surface. When intermediate and top coats are applied to the curved surface, the paint may flow, causing the paint to show through or impairing the smoothness of the painted surface. For this reason, in areas where appearance is important, such as door hemmings, measures have been taken to improve the appearance of the paint by minimizing the amount of paint coming off, such as using a gun with a flat nozzle tip. Examples of body sealers include those whose main ingredient is polyvinyl chloride (hereinafter referred to as PvC body sealer) and those whose main ingredient is urethane (hereinafter referred to as urethane body sealer).
There is. PVC body sealers are mainly composed of vinyl chloride resin and are mixed with fillers, plasticizers, stabilizers, additives, and the like. An example thereof is disclosed in Japanese Unexamined Patent Publication No. 62-45641. As mentioned above, PVC body sealers contain materials that are easily extracted into the layering agent in the paint, and these materials are molten in the body sealer and have high compatibility with the intermediate and top coats. Therefore, when medium paints and top coats are layered, they easily migrate into the paint film, which may inhibit the hardening of the paint film.On the other hand, the paint may be absorbed into the body sealer, causing matting. Also, paintability is not good when applying intermediate and top coats. Urethane-based body sealers are thermosetting polyurethane,
It is a mixture of fillers and various additives. That-
An example is disclosed in Japanese Patent Application Laid-Open No. 190516/1983. When using a urethane-based body sealer, there is no problem when applying the intermediate coat and top coat, and paintability equivalent to steel plate can be obtained. However, since urethane is hydrolyzed by water, it has inferior rust prevention properties compared to PVC body sealers. Also, because it is expensive, it is only used in very limited areas.

のものが使用可能である。A method of sealing a joint gap to which the present invention is applied in order to achieve the above object is to seal the joint between member 5 and member 6 with an inner layer body sealer mainly made of polyvinyl chloride, as shown in FIG. Cover the surface with outer layer body sealer 2 whose main ingredient is urethane? ttm sealing method. Inner body sealer I and outer body sealer 2 are supplied from separate sources 23. The inner layer body sealer 1 is discharged from a discharge port 25 which is adjacent to the discharge port 026 of the outer layer body sealer 2 and is located closer to the joint of the members 5 and 6 than the discharge port 26 of the outer layer body sealer 2, and the outer layer body sealer 2 is It is discharged at the same time as the inner layer body sealer 1 is discharged to seal the joint gap between the members 5 and 6. As the PVC body sealer l for the inner layer, for example, the one disclosed in the above-mentioned Japanese Unexamined Patent Application Publication No. 62-45641 or other known sealers can be used. As the urethane-based body sealer 2 for the outer layer, for example, the one disclosed in the above-mentioned Japanese Patent Application Laid-open No. 190516/1983 or a known one can be used.

得ることが出来る他、防錆性も向上する。A two-layer body sealer layer is obtained by applying an inner PVC body sealer 1 to the joint between members 5 and 6, and simultaneously applying an outer urethane body sealer 2 to cover it. The inner layer of the body sealer layer is a highly rust-proof PVC body sealer, which prevents rust from forming. Since the outer layer of the body sealer layer uses urethane body sealer 2, which has good paintability for intermediate and top coats, a painted appearance equivalent to that of a steel plate can be obtained. Since the surface of the PVC body sealer 1 is covered with the urethane body sealer 2, the plasticizer in the PVC body sealer 1 will not transfer to the intermediate coat or top coat and will not volatilize.
Therefore, the elasticity of the PVC body sealer is maintained, the occurrence of sealer cracking is reduced and durability is improved, and the curing of the intermediate coat and top coat is inhibited and the crosslinking density is cured without significantly decreasing. As a result, not only can a good coating appearance be obtained at the sealing portion, but also rust prevention properties are improved.
