Abstract

(57) [Summary] [Structure] A resin molded body 4 in which a fusion-bonding varnish is applied to the outer peripheral surface of a round wire 5b having resilience, and a resin 6 is extruded on the outer periphery thereof to embed a reinforcing member. is there. [Effect] Since the fusion-bonding round wire 5 in which the fusible varnish is applied to the outer peripheral surface of the restoration-resilient round wire 5b is used as the reinforcing member,
A very long product can be manufactured as compared with the conventional tape-like reinforcing member. Therefore, the number of times the reinforcing member is supplied to the supply device of the extrusion line can be reduced. Further, since the round wire 5b has no directionality and is hard to be deformed, it can be easily embedded in a predetermined position of the resin molded body 4, and as a result, the linear speed of the extrusion line can be made faster than in the past, and the productivity is improved. To do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin molded product in which a round wire having a restoring property is embedded inside a resin for reinforcement or prevention of deformation.

[0002]

[Prior Art]

 A resin molded body in which a reinforcing member is embedded in a resin is known for the purpose of reinforcement or prevention of resin shrinkage deformation due to temperature change. As an example, as shown in FIG. 2, a resin molded body 1 in which a resin layer 3 made of polyvinyl chloride is provided on both surfaces of a tape-shaped reinforcing member 2 made of aluminum with an adhesive 2a interposed therebetween is known. .. As shown in FIG. 3, such a resin molded body 1 continuously supplies a tape-shaped reinforcing member 2 having adhesive materials 2a applied to both surfaces thereof in advance and a tape-shaped reinforcing member 2 on the outer peripheral surface thereof. It is manufactured using an extrusion line including an extruder 11 for extruding a resin, a cooling tank 12 for cooling the extruded resin, and a cutting device 13 for cutting the resin into a predetermined length. In the resin molded body 1 having such a structure, the presence of the reinforcing member 2 prevents the resin layer 3 from being deformed due to an external force or a temperature change.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional resin molded body, since the reinforcing member 2 has a tape shape, it is effective only for the external force from one direction. Also in the manufacturing, since the reinforcing member 2 has a tape-like shape, the length wound around the bobbin was short and only the strip length of about 500 m could be continuously supplied. Therefore, it was necessary to frequently supply the reinforcement member 2 to the supply device 10 of the extrusion line. Furthermore, it was difficult to arrange the reinforcing member 2 in the resin 3 at a predetermined position. Therefore, it is an object of the present invention to provide a resin molded product that can further prevent deformation and contraction due to external force or temperature change and improve productivity.

[0004]

[Means for Solving the Problems]

 In the resin molded product of the present invention, a fusible varnish is applied on the outer peripheral surface of a round wire having resilience, resin is extruded onto the outer circumference in a predetermined shape, and the fusion varnish is heated by the heat at the time of extrusion. Is characterized in that the round wire is melted and the round wire is adhered to the resin.

[0005]

【Example】

 An embodiment of the resin molding of the present invention will be shown below. First, as shown in FIG. 1, a polyester-based heat-fusible varnish was applied and baked on the outer periphery of a long brass round wire 5a to form a fusion-bonding layer 5b, which was a fusion-bonding round wire 5. Then, a resin layer 6 made of polyvinyl chloride was extruded on the outer circumference of the fusion-bonded round wire 5 and cut into a predetermined length to obtain a resin molded body 4. Although polyvinyl chloride and polyester fusion varnish are used as the resin layer and the fusion layer in the above-mentioned embodiments, they may be formed of other materials. The material of the round wire may be aluminum as in the conventional case, but brass, stainless steel, or the like, which is elastically deformable, is preferable. As still another embodiment, a plurality of round wires 5 fused in parallel may be embedded. By doing so, the surface area of the fusion varnish layer is increased, the adhesion with the resin layer is strengthened, and the reinforcing effect is further enhanced.

[0006]

[Effect of the device]

 In the resin molded product of the present invention, a reinforcing member coated with a fusible varnish on the entire outer periphery of the round wire is used, so that a long product having a strip length of about 10,000 m can be manufactured. Therefore, the number of times the reinforcing member is supplied to the supply device of the extrusion line can be reduced. Further, since the round wire has a circular cross section, it can withstand an external force from a wide range and can be easily arranged at a predetermined position in the resin layer. Therefore, it is less likely to be deformed during extrusion and the linear velocity of the extrusion line can be increased as compared with the conventional method, so that productivity can be improved.
