Abstract

PURPOSE:To improve radio wave reflectivity and long-period weather resistance by forming a radio wave reflecting layer of room-temperature plastic metallic foil having adjacent slits provided passing by one another at end parts, and covering said radio wave reflecting layer with a synthetic resin layer for reinforcement. CONSTITUTION:The radio wave reflecting layer 2 is formed on the room-temperature plastic metallic foil having adjacent slits 3 provided passing by one another at their end parts. The concave curved surface of the reflecting layer 2 is covered with a synthetic resin layer 3 with radio wave transmissivity, and the convex back surface is constituted in one body with the synthetic resin reinforcing layer 5. Therefore, the room-temperature plastic metallic foil expands on a three-dimensional curved surface uniformly because of the slits 3, and the resin layers 4 and 5 are combined together through the slits 3; and the reflecting layer 2 is reinforced by the covering and shielded from the outside air, so that raio wave reflectivity and long-period weather resistance are improved.

Description

[Detailed description of the invention] Mizuben Akira number: 1. Concerning a parabolic container made of 44 synthetic resins such as reinforced plastic, especially molding and IF, 1: good quality, 1. Radio wave counter layer shaped J11. Radio wave collection;
It concerns a parabolic refractor with good efficiency.

? , Y* parabolic refractor is made of j′ aluminum or [R1] C2, aluminum cum (:1
It is a small parabola with a straight line fY of 1 m or less, and its forming is done by spatula drawing or 1,1 sheet metal press forming. In the case of spatula drawing, there is a limit to the number of times B can be produced commercially.

J, In the case of sheet metal press forming, there is springback, and a high press mold setting; 11 techniques are required.
In order to carry out the drawing process described below, a multi-step nosue culm, which has been specially installed with a high degree of precision, is required. Even in the case of 4, extremely advanced forming techniques are required to form the aluminum plate without causing cracks or wrinkles.

In addition, in order to increase the radio wave reflectivity (=1) of parabolic refractors using synthetic resins such as those made of R1, metal spraying, sputtering, and metal foil pasting on the surface of the molded product are required. However, in this method, the formation of the conductive film is a post-processing process.
If the synthetic resin monthly rate is Borini (-stell, polypropylene, polypropylene, poly[-tylene, ΔBS1 phenol or melamine, etc.), the adhesion of the metal film is poor, and the I think I'm going to apply a precondition jIP to the j interface.
