The present invention relates to a method of processing rubber glass launch channel corner portions. The corners of a glass launch channel must be shaped to relieve stress and prevent the ingress of wind and rain, and the same applies to rubber glass launch channels. As a method for forming rubber glass launch channel corner sections, a method is known in which rubber or synthetic resin is injected into a corner space provided with a notch or notch to match the window frame. However, among these methods, the rubber injection molding method requires vulcanization of the injected rubber, which takes time. Furthermore, the method of injecting synthetic resin has drawbacks such as low adhesive strength with rubber and easy separation of rubber and synthetic resin. Especially when the rubber is a blend rubber (EP/NR) of ethylene/propylene rubber (e.g. EPM, EPDM) and natural rubber (NR) or a blend rubber (EP/NR) of ethylene/propylene rubber and styrene-butadiene rubber (SBR). /
Rubbers containing ethylene/propylene rubber, such as SBR), have poor adhesion with synthetic resins and separate very easily. Another known method is to add a small hole to the cutout part of a rubber glass run, inject synthetic resin into the hole, and physically suture it (Utility Model Publication No. 6617, 1982). However, the corners created using this method lack strength because they are physically sewn together, and there are gaps, making it difficult to prevent wind and rain from entering. As a solution to the above problem, ethylene/vinyl acetate copolymer (EV) was added to the corner space.
A method of injection injection exists as a prior art (Japanese Unexamined Patent Publication No. 170624/1983). However, this method has the disadvantage that if an EVA with a high vinyl acetate (VA) content is used, the heat resistance of the corner portion will be poor, and if the VA content is low, the adhesive strength will be low. As a way to solve this problem, a cross-linked type is installed in the corner space.
There is a method of filling EVA or a method of filling the corner space with hot melt adhesive after surface treatment of the rubber surface. However, both cross-linked EVA and hot-melt adhesive are expensive, and any method beyond filling them will inevitably be expensive. The present invention was made with the aim of improving the above-mentioned drawbacks of the corner portions of conventional glass launch channels, and provides a method for forming rubber glass launch channel corner sections that is inexpensive and has excellent adhesive strength and heat resistance. It is something. The method for forming a rubber glass launch channel corner portion of the present invention involves surface-treating the end face or notch end face of a rubber glass launch channel member, applying a solvent-based hot melt adhesive to the surface-treated end face or notch end face, and chemically The end surfaces or notched end surfaces to which the adhesive is bonded are placed opposite each other to form a corner in the mold, and the corner space is filled with a high-temperature thermoplastic resin. The present invention is characterized in that the adhesive is activated by the heat of the thermoplastic resin, and the rubber glass launch channel member and the thermoplastic resin are chemically bonded via the adhesive. The corner space 3 is formed by making a notch 5 in the back of the glass launch channel member 1 (FIG. 1) and then opening the notch 5 in accordance with the shape of the window frame (FIG. 2a). In addition, two glass launch channel members 1
They may be formed by facing each other in accordance with the shape of the window frame (FIG. 2b). In the latter case, the two glass launch channel members may be made of different materials. The glass launch channel member 1 is made of vulcanized rubber, and any type of rubber may be used, for example, EP/NR or EP/SBR. In the present invention, the end surface 2 or notch end surface 2' of the glass launch channel member 1 is first subjected to surface treatment before filling. The surface treatment is carried out to activate the rubber surface, and the treatment method itself is known. For example, when the rubber is EP/SBR or EP/NR, a 2% solution of trichloroisocyanuric acid (C 3 Cl 3 N 3 O 3 ) or a solution of tertiary butyl hypochloride is applied to the end face or notch end face. 2000 if the rubber is EPM or EPDM
Irradiate the end face or notch end face with ultraviolet rays of Å or less for about 10 seconds. After the surface treatment, a hot melt adhesive is applied to the end face or notch end face for adhesion. Hot melt adhesives include those using EVA, polyamide, polyester, polyurethane, etc. as a base polymer, but urethane-based or nylon-based solvent-based hot melt adhesives are preferred. Among these, when heat resistance is particularly required, adhesion during heat resistance can be improved by adding isocyanate compounds with terminal NCO groups to urethane systems and melamine compounds such as cyanamide to nylon systems. Can be done. Next, the space 3 is filled with a high temperature thermoplastic resin. Examples of thermoplastic resins used include polyvinyl chloride, polyethylene, polypropylene, polystyrene, and polyurethane. Of course, it is not limited to these. Filling is usually carried out by setting the glass launch channel member 1 in a mold and injecting thermoplastic resin into the space 3 (FIG. 3). The heat of the injected high-temperature thermoplastic resin activates the solvent-type hot melt adhesive, exhibits adhesive strength, and adheres to the thermoplastic resin. Therefore, when cooled, the rubber glass launch channel member and the thermoplastic resin are strongly chemically bonded via the adhesive. Example 1 After the end face of EP/SBR rubber was surface treated with a 2% solution of trichloroisocyanuric acid, a 10% methanol solution of nylon hot melt adhesive (6,6-10, aromatic diamine tripolymer) was applied to the end face. It was dried and set in a mold. A test piece was created by injecting PVC into the mold. A tensile test and a creep test were conducted on the test piece thus obtained. The tensile test was conducted at room temperature and 80℃. The breaking strength at room temperature was 20Kg/cm 2 and at 80℃ was 2.7Kg/cm 2
It was hot. The creep test was conducted at 70°C and 80°C, and the deformation rate at 70°C was 10% and the deformation rate at 80°C was 18%. The above results are shown in Table 1 along with comparative examples. The breaking strength in the tensile test indicates adhesive strength, and the deformation rate in the creep test indicates heat resistance. As can be seen from Table 1, the rubber glass launch channel corner section according to the present invention has excellent adhesive strength and heat resistance. It turns out that there is also a combination. Moreover, it is inexpensive because it only requires applying and drying a solution containing an expensive hot melt adhesive, and the amount used is extremely small. Comparative Example 1 EP/SBR rubber was directly set in a mold, and the mold was filled with polyvinyl chloride (PVC). The results of the tensile test and creep test are shown in Table 1. Comparative Example 2 EP/SBR rubber was set in a mold as it was, and EVA (VA content 28 wt%) was injected into the mold. The test results are shown in Table 1. Comparative Example 3 A test piece was prepared in the same manner as Comparative Example 2 except that cross-linked EVA was injected instead of EVA. The test results are shown in Table 1. Comparative Example 4 The end face of EP/SBR rubber was surface treated with a 2% solution of trichloroisocyanuric acid and set in a mold. A test piece was prepared by injecting a hot melt adhesive containing nylon as a base polymer into the mold. The test was conducted in the same manner as in Example 1. The test results are shown in Table 1.

形方法。1 Surface-treating the end face or notch end face of a rubber glass launch channel member, applying a solvent-based hot melt adhesive to the surface-treated end face or notch end face to chemically bond the end face or notch end face to which the adhesive is attached. The notched end surfaces are arranged to face each other to form a corner in the mold, the corner space is filled with a high temperature thermoplastic resin, and the adhesive is activated by the heat of the high temperature thermoplastic resin. A method for forming a corner portion of a rubber glass launch channel, comprising: chemically adhering the rubber glass launch channel member and the thermoplastic resin via the adhesive.
