本発明は金属製防蝕体及びその製造方法に関す

キやメタリコンに比べると防蝕効果は優れている
が、なおピンホールの発生を避け得ないため、数
回にわたり入念な塗装をする必要があり、煩瑣な
欠点があつた。 Since the surface of iron-based metals is easily rusted and corroded, anti-corrosion measures such as plating, metallic coating, and painting have traditionally been taken to prevent rusting and corrosion. Among these methods, plating is superior in terms of making the surface beautiful, but the waste liquid causes pollution, is expensive to implement, and has the disadvantage that its corrosion prevention effect is not sufficient. Metallicon is made by thermally spraying other rust-resistant metals into particles to create a porous layer of metal that adheres to the surface, similar to a chestnut paste. Therefore, the surface of metallicon contains a large number of pores, which has the disadvantage that it does not have a sufficient corrosion protection effect, and since it is simply a porous layer of metal attached to the surface, it is difficult to form pores due to external force. The problem was that the quality layer easily peeled off. Furthermore, although painting has a superior corrosion-proofing effect compared to the above-mentioned plating or metallicon, it still cannot avoid the occurrence of pinholes, so it is necessary to carefully apply the paint several times, which has a troublesome drawback.
本発明者はかかる従来の欠点に鑑み鋭意研究の

A synthetic resin coating film 6 is formed by solution coating or the like.
As the resin forming the synthetic resin coating film 6, a thermosetting resin different from the resin forming the thermosetting resin layer 5, or a thermoplastic resin is used as a paint. Powder coating is preferable as a method for forming the synthetic resin coating film 6. According to powder coating, powdered resin is melted and fused to form a coating film, so a smooth surface with no pinholes can be obtained. A coating film of

The surface of an iron pipe with an outer diameter of 25 mm, a wall thickness of 3 mm, and a length of 1 m was polished to an unevenness with an average roughness of 30 microns using a #30 cast iron abrasive. Next, a zinc wire was sprayed on top of this using a gas-sprayed metallicon to a thickness of 100 mm.
A micron layer of zinc was formed. Next, the iron pipe was heated at 430°C for 1 minute using a high-frequency induction heating device, and the joint surface between the iron pipe and the zinc layer was rapidly raised in temperature to melt and integrate. At this time, many vacancies remained in the zinc layer. Subsequently, after cooling the iron pipe, an undercoat layer was formed on the zinc layer using phenoxy resin (YP-40-ASM40) manufactured by Toto Kasei Co., Ltd. This phenoxy resin is curable at high temperatures and has a curing initiation temperature of 170 to 180°C. As a primer, 40 parts by weight of phenoxy resin, 20 parts by weight of titanium oxide, and 20 parts by weight of talc are dissolved or dispersed in 10 parts by weight of cellosolve acetate and 10 parts by weight of xylene, and then 10 parts by weight of Desmodyur AP is added to this.
was dissolved in 90 parts by weight of xylene and used in a 1:1 ratio. After applying the primer, the temperature of the iron pipe was raised to 220°C, and all the solvents such as cellosolve acetate volatilized at the initial stage. The above resin was cured by holding at 220°C for 10 minutes. Next, a polyester powder paint was applied on top of it by electrostatic powder coating, and 200%
A coating film was formed by holding at ℃ for 20 minutes.

In addition, no abnormalities such as peeling or blistering of the coating film were observed even after a 60-minute boiling test. or,
No abnormality was observed even after 500 hours of salt spray resistance test.

できる。 As described in detail above, the present invention involves forming a porous layer of metal on the roughened surface of a metal base material, and forming an alloy layer by melting the bonding surface between the base material and the porous layer. As a result, the adhesion between the base material and the porous layer is strong, and the porous layer does not peel off due to external forces such as bending, impact, and distortion due to expansion and contraction due to heating, resulting in excellent durability. It can be made into a corrosion-resistant body.

It is easy to form and has excellent secondary processability such as bending of metal corrosion-resistant bodies.

It is possible to form an alloy metal by melting only the joint surface between the base material and the porous layer. At this time, since the sprayed layer is porous, its thermal conductivity is low, so the heat conduction is suppressed due to its insulation effect, and only the part in contact with the base material is melted, effectively forming an alloy with the base material. , are strongly integrated not only mechanically but also chemically.

きる。 In addition, the voids in the porous layer with an uneven surface are filled with thermosetting resin, and a synthetic resin coating is formed on top of it, so the porous layer and thermosetting resin blend well and bond well. It is possible to obtain a corrosion-resistant body which is strong and has a synthetic resin coating firmly adhered thereto.
