があった。2. Description of the Related Art Conventionally, synthetic resins exemplified by polyolefin resins such as vinyl chloride resin, nylon resin and polypropylene resin have been used for automobile side protection moldings and rocker panel moldings. However, the resin moldings produced by molding these synthetic resins alone have low rigidity and are easily affected by the installation environment, and the dimensional stability deteriorates during repeated expansion and contraction due to temperature changes, especially in the longitudinal direction. There was a risk of distortion.

が困難であった。In order to make up for this drawback, a resin molded body in which a synthetic resin is coated on a stainless steel core material formed into a tape or a predetermined shape for molding has been widely used, but the metal portion is large. Therefore, the weight becomes heavy, the cost is high, and it is difficult to process the core material into a predetermined sectional shape.

る。Therefore, as shown in Japanese Patent Application No. 3-67562, a resin is extruded onto the outer periphery of a shrinkage-preventing material in which a fusion-bonding layer made of a heat-fusion varnish such as polyester is provided on a wire having high tensile strength. A resin molded body has been proposed in which a fusion layer is melted by heat during extrusion to bond a wire and a resin. In such a resin molded product, since the wire rod has high tensile strength and the adhesion between the wire rod and the resin is good, it is known that the dimensional stability of the resin molded product is not deteriorated even when the temperature is changed. Has been.

かながらも反ってしまうおそれがあった。The cross-sectional shape of the resin molded body is becoming more and more complicated year by year, and a wire rod having a fusion layer developed by the present applicants in order to improve the moldability of its fine portion is provided. It is also practiced to embed in a fine portion of a resin molded body. However, when the wire rod as described above is embedded in the details or protruding parts of the resin molded body, its excellent adhesiveness rather causes damage, and due to the difference in the coefficient of thermal expansion between the wire rod and the resin, the wire rod is embedded. Moreover, there is a possibility that the details and protruding portions of the resin molded body may warp although they are slight.

In the reinforcing material according to the first aspect of the present invention, the reinforcing material that is used by being embedded in the resin molded body has a releasability from the resin molded body with respect to the metal wire and the metal wire directly or through another layer. The gist of the present invention is to have a coating layer made of the resin.

状に加工するなども、本発明に包含される。The metal wire used in the present invention preferably has a high tensile strength, that is, a tensile strength of 400 N / mm 2 or more, and specific examples thereof include brass, phosphor bronze, stainless steel, nickel silver, iron and the like. . Tensile strength is 400N
/ Mm2 or more metal is less likely to be deformed by external force,
Since it has a straightening property, it is suitable as a core material. When a metal wire having a tensile strength of less than 400 N / mm 2 is used for the resin molded body, the metal wire may be broken due to contraction and expansion of the resin layer extruded on the coating layer. Further, those obtained by plating these metals are preferable because they have a high rust preventive effect.
The shape of the metal wire is preferably circular in cross section or a combination of a plurality of wire having circular cross section. The metal wire rod having such a shape has no directionality as compared with other cross-sectional shapes, can be easily thinned, and has good moldability. Particularly, in the latter case of a stranded wire using a wire rod having tensile strength, not only the tensile strength but also excellent flexibility is combined. In addition,
The present invention also includes roughening the outer peripheral surface of the metal wire rod, corrugating the metal wire rod in the longitudinal direction, and the like in order to improve the adhesiveness with the coating layer to be coated.

When it is embedded in a resin molded body as a resin, that is, a reinforcing material, a pulling force of 20 N is applied to the resin layer.
Refers to a resin that shows a low value as below, for example, a fluorine-based resin,
Examples include silicone-based resins and polyamide resins (nylon). In addition, the resin layer of the resin molded body is a resin having relatively few polar groups such as polyolefin resin, ABS / PV
In the case of C alloy, EPDM, etc., it is possible to use a polyester resin that does not adhere to them as a coating layer. These resins having releasability are applied directly onto the metal wire or through another layer, and baked sufficiently so as not to melt at the extrusion temperature when the resin layer is extruded.

Even when embedded, the resin layer does not warp. The resin molded body of the present invention has a molded shape when the resin molded body is molded by bending or the like by the action of the embedded metal wire although the resin layer and the reinforcing material are not bonded to each other. Can be held for a long time. The reinforcing material of the present invention exerts its effect particularly when it is embedded in the protruding portion or the details of the resin molded body which is likely to warp.
Further, in the present invention, when the resin layer of the resin molded body is extrusion molded, "dripping" or deformation of the extruded resin is prevented, the extrusion dimensional accuracy of the resin molded body is improved, and the workability is improved. .
