表面光沢押出品の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a surface-gloss extruded product made of synthetic resin, which includes an insert I section which is formed by bending an insert I section and is extrusion coated with a resin material.

う。このとき。Conventionally, when manufacturing a synthetic resin cytomolding (extruded product) A equipped with an insert part l for inserting a car body access clip as shown in Fig. 1, the inserts I and 2 immediately after bending were made of resin material. The insert part 1 is formed by extrusion coating, and the main body part 3 is also extruded integrally with the insert part 1. At this time.

となる。Since the insert 2 vibrates within the extrusion tie due to vibrations generated from a roll forming machine for bending, minute undulations occur on the surface of the main body 3 that is integrally extruded. This waving does not pose a problem in extruded products with a matte or textured surface, but in the case of extruded products with a glossy surface, it appears as a wavy pattern and becomes a product defect. Therefore, in order to obtain a glossy surface product with such a structure as an extrusion molded product, the product must be immersed in a solvent after molding, heated to melt the surface, or painted. However, the process was complicated and the cost was high, so even though there was a demand for such a product, it was not practical, so it was not actually produced. In addition, since there is a large difference in the wall thickness of the main body 3 between the surface and both sides, shrinkage is likely to occur due to resin shrinkage during curing, and this shrinkage is noticeable in the case of extruded products with a glossy surface and can lead to product defects.・Causes

ることに４８ ｍを有する。In view of the above, the present invention provides an insert in which a bent insert is extruded and coated with a resin material.
The purpose of the present invention is to provide a method for manufacturing a glossy surface extrusion product made of synthetic resin with a main body portion so that wavy patterns and shrinkage do not occur on the surface of the main body portion. , in a method for manufacturing an extruded product made of synthetic resin having an insert portion in which a bent insert is extruded and coated with a resin material, the main body portion and the insert portion having approximately the same wall thickness and having a glossy surface are separated. It has a length of 48 m after being integrated into the body.
以下、この発明の方法を図例に基づいて説明する。Hereinafter, the method of the present invention will be explained based on illustrated examples.

Let us take as an example a side molding B having a configuration consisting of B.

入される。As shown in Figure 3, inserts of 02~(1', 5mmt) that are unwound from a reel stand (not shown) are degreased one after another in a 75-air trichloroethane washer 5, and then dip-coated. An adhesive is applied at 4i a 6, dried in a hot air dryer 7, further bent in a roll forming machine 8, and introduced into an extrusion head of an extrusion device 9.

い。For this reason, the insert portion IB coated with the resin material M of the insert 2B or PVCL and the main body portion 3B having a glossy surface are separated and extruded simultaneously. Therefore, even if vibrations from the roll forming machine 8 are transmitted to the insert 2B, the extrusion of the main body portion 3B is not affected by the vibrations, and even if the extruded product has a glossy surface, no wavy pattern is generated on the surface of the extruded product.

means the presser roll 21 disposed in front of the extrusion tie 15.
and the receiving roll 22. At this time, the resin materials of the insert part IB and the main body part 3B are both in a semi-molten state because they have just been extruded, and both parts are reliably crimped and integrated.

要である。Note that the insert 2B does not need to be coated on the entire surface, but only on the main body 3.
It is sufficient that only the side to be bonded to B is coated. Further, if the inserter 2B has high rigidity, the receiving o-ru 22 is not necessary.

波打ち模様は発生しない。In this way, the main body part 3B and the insert part IB are formed separately and then integrated, so that the main body part 3B is not affected by the vibration of the insert 2B during extrusion, and there is no wavy pattern on the surface of the main body part 3B. Does not occur.
また、本体部３Ｂは略同−肉厚であるので押出後の硬化

い。In addition, since the main body portion 3B has approximately the same thickness, there is almost no occurrence of shrinkage due to resin contraction during curing after extrusion.
