Abstract

PURPOSE:To remove water intruded between a dam rubber and window frame and adhesive, by providing repellency to the dam rubber inserted between the window panel and window frame for preventing the adhesive from bulging. CONSTITUTION:A dam rubber 9 for preventing the adhesive from bulging into the cabin is provided on the inner face at the circumferential section of window panel 1. Said adhesive is filled in the outside of said dam rubber 9 to secure the window panel 1 and window frame 4. Here, the dam rubber 9 is formed with an adhesive section 9a with the window panel 1 and a shielding section 9b curved to the cabin said and repellency is provided to the dam rubber 9 itself. For that purpose, silicon is mixed in the material for forming the dam rubber 9 and molded. Alternatively, a treated layer 10 where repellent surface treating agent is applied and burnt is provided on the surface of dam rubber 9.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for fixing a wind panel in an automobile window, and more particularly to an adhesive type window in which the peripheral edge of the wind panel and the wind frame are fixed by interposing an adhesive between the wind panel and the wind frame.

In the conventional adhesive type window, as shown in FIG. After filling the adhesive 3, the wind panel 1 and the wind frame 4 are fixed by pressing them against the wind frame 4 l[1, ll and bringing them into close contact.In the figure, 5 is the wind molding, and 6 is the body. It shows.

However, in such a conventional fixed-layer window fixing structure, the wind panel 1 is attached to the wind frame 4.
When pressed, air pockets 7 shown in FIG. 2 are generated, resulting in insufficient bonding strength due to a decrease in bonding area.
Alternatively, when the air in the air reservoir 7 expands and escapes while the backing agent 3 is not hardened, a fine gap 8 shown in FIG. It had the disadvantage of entering the room. Furthermore, if the wind frame 4 has a step at the joint or deformation due to spot welding with other parts, the adhesive pressed onto these deformed parts will not be able to fully cover the step and deformation and will cause slight damage. It also has the disadvantage that gaps are often formed, and the intrusion of moisture due to capillary action through these gaps is unavoidable.

The purpose of the present invention is to improve the various drawbacks of the conventional adhesive-type window fixing structure as described above, and to remove moisture that enters between the adhesive and the dam rubber and the wind frame. In order to achieve this, the main objective is to impart a water-repellent function to the dumb rubber.

The present invention will be described in detail below with reference to the drawings.

That is, the dam rubber 9 shown in FIG. 4 consists of a bonded portion 9a to the wind panel 1, and a shielding portion 9b curved from the inner end of the bonded portion 9a toward the imperial family.
It has a letter shape. That is, the first embodiment of the present invention is characterized in that the dumb rubber 9 itself is made water repellent. The method is to mix silicone or water-repellent wax in a predetermined ratio into the material forming the dumb rubber 9, and then mold it into one piece. Water-based substances exhibit waterproof function. As an example of the water repellent substance, there is a silicon-based resin or wax made of an organosiloxane composition containing silicon atoms, and by mixing 20 to 50% by weight of these into the rubber layer, the above-mentioned characteristics can be improved. A dumb rubber having the following properties is obtained.

Next, a second embodiment of the present invention will be described. That is, as shown in FIG. 5, the assembly is performed by providing a treatment layer 10 on a predetermined surface of the dam rubber 9 by applying and baking a land-based surface treatment agent. The same material as in the first embodiment is used for the water-repellent surface treatment agent, and it is applied onto a predetermined surface of the dam rubber 9 or, if necessary, over the entire surface, and a baking treatment is also used to form a layer. According to the embodiment shown in Figure 5, an air pocket is generated between the dam rubber 9 and the adhesive 3, and a gap is generated between the adhesive 3 and the wind frame 4 or the wind panel 1, allowing moisture to enter. This can be effectively stopped by the treatment layer 10, thereby preventing moisture from entering the vehicle interior.

Next, a third embodiment of the present invention will be explained. That is, in the third embodiment, a breathable open-cell material is selected as the material for the dumb rubber 9, and the material is impregnated with a water-repellent substance such as silicone or wax. There is. In the above implementation, the material of the dumb rubber 9 can be easily imparted with water repellency by immersing the material of the dumb rubber 9 in a melting agent such as silicone or wax for a certain period of time.

Next, a fourth embodiment of the present invention will be explained. That is, it is manufactured in the same manner as the first embodiment, and is characterized in that the dam rubber 9 itself is made water repellent, and a large number of air holes are provided inside the dam rubber 9.

In terms of manufacturability, it is possible to select a material that generates a large number of bubbles during molding, mix a water-breaking substance into this material, and then mold it. According to this embodiment, the dam rubber 9 itself has both air permeability and water repellency, so even if an air pocket 7 as shown in FIG. 9 and is discharged into the vehicle interior, there is no risk of the minute gap 8 shown in FIG. 3 occurring, and there is an advantage that the waterproofing effect is more complete.

The method of attaching the wind panel 1 to the wind frame 4 of the body 6 using the dam rubber 9 shown on the valley underflow side is the same as the conventional method. Pasting part 9a
is pasted slightly inward from the edge of the wind panel 1.

Next, the adhesive 3 is ejected from the nozzle tip of the sealant gun and filled into the recess surrounded by the sticking part 9a and the shielding part 9b. Next, move the wind panel 1 to the wind frame 4.
The installation is completed by pressing it onto your back and holding it.

The water-breaking substance used in each of the above examples is made of a silicon-containing organosilsaquin composition, commonly known as silicone, and has the property of curing at room temperature or under heating. are doing. Moreover, when coated on other materials, 1
11F In addition to water repellency, weather resistance, non-circular? f14. It also has excellent abrasion resistance, and has the effect of improving slipperiness and preventing ``squeak''.

The present invention is characterized in that a water-repellent function is imparted by mixing or coating a carbon substance having the above-mentioned characteristics inside or on the surface of the dumb rubber.

As explained above, in the present invention, water-repellent function is imparted to the dam rubber for preventing adhesive from extruding in the fixed structure of the adhesive type window.
Even if a curved gap occurs, a structure is obtained in which rainwater, washing water, etc. are stopped by the dam rubber and do not enter the vehicle interior. Furthermore, even if moisture infiltrates through gaps caused by steps or deformations such as spot welding that occur in the wind frame 4, the surface tension of the water that comes into contact with the dam rubber, which has water-breaking properties, becomes relatively strong. It exhibits the effect of preventing moisture from entering the vehicle interior, and is useful as a wind panel fixing structure for automatic vehicles.
