[Technical Field] The present invention relates to a screwing agent formed with a spray film for rust prevention, and, for example, according to Japanese Industrial Standard JIS Η 8 3 00 : Aluminum and sprays of such alloys. Zinc, aluminum, and the spray coating of these alloys are used in the formation of alloys, and aluminum-magnesium alloys, such as squeezing squeezing squeegees, bolts, and methods for their manufacture. [Prior Art] Corrosion measures for steel structures such as steel trusses of road bridges The surface of steel structures is formed by spraying a highly corrosion-resistant alloy. Moreover, the steel structure of this kind must be structurally connected at the site, usually by a strong bolt (ΗΤΒ). However, in the strong bolt and the nut itself, there is no high corrosion resistance film of the main body of the body, and the steel structure of the strong bolt and the nut is short, and must be maintained by the strong bolt and the nut. Therefore, it is desirable to have the same surface as the steel structure, and a strong corrosion-resistant film is also formed in the strong cap. For example, in the entire screw portion of the bolt body of Patent Document 1, a bolt of a spray layer having a thickness of 10 to 150 μm made of gold such as molybdenum, chromium or tungsten is provided. Further, 2 describes a bolt which adheres a particle size of 1 Ομιη particles to a surface of a compression screw by a high-speed flame spraying method. Bolting with sealing hole 2005 Γ Zinc · Purpose of the implementation of aluminum, zinc and aluminum body tight, in the factory, high corrosion resistance skin on-site connection, and the formation of nuts such as steel construction durability years than the durability of the number of years In the case of the bolts and the snails, the singularity of the singularity or the alloy is described in the following paragraphs: [Patent Document 1] In addition, in order to use the steel structure body which forms a highly corrosion-resistant film, and the strong bolts and nuts of the same durability years, as shown in the patent documents 1 and 2, the screw part of not only a strong bolt, but also a strong bolt is considered. And whether or not the entire nut has a high corrosion-resistant spray film. However, it has been practically attempted to use a strong bolt and a nut which are sprayed on the entire surface to form a highly corrosion-resistant film to lock the steel structure, and it has been found that the required axial force is not obtained by locking with a specific tightening torque. The problem to be solved by the present invention is to obtain the required axial force when the bolt for forming the rust-preventing spray film is locked by a specific tightening torque. The sealing treatment agent of the present invention is a sealing treatment agent for a bolt having a rust-preventing spray film formed on at least a screw portion, and contains 1 to 10% by mass of wax. According to the sealing treatment agent of the present invention, at least the bolt forming the rust-preventing spray film for the screw portion is subjected to the sealing treatment, and the wax is fixed to the screw portion of the bolt together with the sealing treatment agent. With this bolt, the required axial force can be obtained because the wax fixed to the screw portion reduces the friction with the nut and is locked with a specific locking torque. Further, when the wax contained in the sealing treatment agent is 1% by mass or less, the friction reducing effect with the nut is insufficient. When the specific locking torque is locked, the required axial force cannot be obtained. In addition, when the coating material containing the bolt is applied for the purpose of aesthetics or the like, the sealing treatment agent containing 1 to 5% by mass of the wax is preferably 201231832. When the coating contains more than 5% by mass of the wax in the coating treatment agent, the sealing performance of the sealing treatment agent and the coating is lowered. On the other hand, even if the coating is not carried out, it is preferable that 10% by mass or less is more than ίο% by mass. Since the wax content is too large, the fixing force to the screw portion of the bolt is weakened, and when it is locked, the wax peels off. . Here, the main component of the plugging treatment agent of the present invention is preferably a resin-based sealing agent. As the resin-based sealing agent, an epoxy resin, a stone carbonate resin, a cerium oxide resin, a vinyl resin, a polyester resin, a polyurethane resin, an epoxy carbonate resin, a polyamide resin, and a ring can be used. Oxygen melamine resin and the like. The inventors of the present invention have been careful about the rust-preventing of the quilted body by the bolts and nuts which are formed with the rust-preventing spray film to lock the lapped film having the rust-preventing spray film. When the spray coating surface and the rust-preventing spray coating surface of the bolt and the nut are locked to each other, the sliding surface is sintered, and the soft rust-proof spray coating is integrated with each other, and the lock film cannot be further locked, thereby realizing the present invention. . Further, the squeezing device of the present invention is a squeezing squeezing device for forming a smashed body with a rustproof spray film, the squeezing device comprising: a full body including a head portion and a screw portion a bolt for rust-preventing spray film, and at least a screw portion is sealed with a sealing treatment agent containing 1 to 1% by mass of wax; and a nut for holding the screw portion of the bolt and locking it to the screw portion of the bolt In addition to the inner screw portion and the contact surface on the side of the elastic body, a nut having a rust-preventing spray film is integrally formed. Conventionally, when the squeegee for forming a rust-preventing spray film is formed in the whole, the rust-proof sprayed film surface of the quilt 201231832 and the rust-proof sprayed film surface of the bolt and the nut are slid to each other. When the surface is sintered, the soft rust-preventing spray film is integrated with each other and cannot be further locked. However, in the case of the present invention, the screw portion and the contact surface on the side of the elastic body are not The rust-preventing spray film is formed, and the sliding surface of the nut and the elastic body when the nut is locked, and the sliding surface of the screw portion of the screw and the screw portion of the bolt are provided, and only one of them has a rust-preventing spray film. Therefore, when the nut is locked, there is no possibility that the rust-preventing spray film is integrated on the sliding surface. Moreover, the wax and the sealing treatment agent are fixed to the screw portion of the bolt, and the friction between the nuts can be reduced, and the specific locking torque can be locked to the end. In addition, after the locking of the tightening tool of the present invention, the inner screw portion of the rust-preventing spray film and the contact surface on the side of the squeezing body are not formed on the nut, because they are closely attached to the rust-proof spray film. In addition, the protection of the rust-preventing spray film is obtained. Here, the rust-preventing spray film of the nut is preferably formed by an arc spray method, and the rust-preventing spray film for the bolt is used by the gas jet method. Or the formation of the plasma jet method is preferred. The rust-preventing spray film formed by the arc spray method is more suitable for the rust-preventing spray film formed by the gas jet method or the plasma spray method because of the thicker surface roughness and higher adhesion force. A nut that is rotated by an impact wrench or the like prevents peeling of the rust-preventing spray film. On the other hand, the rust-preventing spray film formed by the gas jet method or the plasma jet method is suitable for bolts because of the fineness of the surface, and the surface of the rust-preventing spray film formed on the screw portion of the bolt is smooth. Easy to lock the nut. -8- 201231832 (1) A sealing agent containing 1 to 10% by mass of wax, and a screw for forming a rust-preventing spray film on the screw portion, and a screw which is fixed to the bolt together with the sealing treatment agent Part, the wax fixed to reduce the friction between the nut and the nut, and locked with a specific locking torque to obtain the required axial force. (2) The rust-preventing spray film is attached to the screw portion of the bolt that is locked to the bolt and is attached to the inner screw portion and the contact surface on the side of the squeezing body. When the sealing cap of the nut containing the sealing agent containing 1% by volume of wax is locked, the rust-preventing spray film is not integrated on the sliding surface, and the screw portion of the bolt is fixed. Hole treatment agent and wax, to reduce the friction between the specific locking torque can be locked to the end, the specific axial force required to lock the locking torque. (3) The anti-rust spray film for the nut is an arc spray method, and the anti-rust spray film for the bolt is formed by a gas jet method or a plasma, and can prevent the anti-shot when the nut is rotated by an impact wrench or the like. The peeling of the film and the surface of the rustproof film formed on the screw portion of the bolt are smooth, and it is easy to lock the nut.

When the surface of the surface is formed by spraying the film, at least the wax portion can be used, the shape of the nut, the shape of the 10, and the snail. In addition, a spray injection pattern for the spray rust is formed with the nut, and FIG. 3 is a view showing the embodiment of the present invention, as shown in FIGS. 1 and 2, and FIG.

As shown in Fig. 3, the surface of the steel passage and the joining plates 102, 103 and the holes 101a, 102a, 103a into which the bolts 1 are inserted are integrally formed with the rustproof spray film l lb, 102b of the alloy. 103b.

The amount of the wax to be added is set to be in the range of 1 to 10% by mass based on the resin-based sealing agent or the like. In the present embodiment, paraffin wax is used. Further, in addition to the animal system, the wax is a petroleum-based paraffin, a microcrystalline cerium, a mineral-based montan wax, a dextran-based FT synthetic wax, a polyethylene hydrazine, a grease-based synthetic wax, and a crucible. When the treatment agent is applied to the purpose of performing a construction including a bolt, etc., a wax containing 1 to 5 mass% of wax is used. For example, the acrylic cerium oxide resin as a resin-based sealing agent is coated with a sealing agent for adding a mass% of paraffin wax, and after drying, the argon-methyl urethane is tightened with the same screw 10 1 each bolt Al-Mg The 3rd surface of 103, the shape is rust-proof. When the main structuring agent is used in the type, the wax can also be waxed or hydrazine hydride. For example, the coating of 1~5 ester resin -10- 201231832 is applied. The addition of sarcophagus is carried out, for example, by diluting the resin-based sealing agent with a diluent, and adding paraffin, and then slowly stirring and mixing by heating with water. On the other hand, when the coating is not applied, a sealing treatment agent containing 8 to 10% by mass of paraffin wax is applied to the resin-based sealing agent. Further, as the resin-based sealer, an epoxy resin, a stone carbonate resin, a cerium oxide resin, a vinyl resin, a polyester resin, a polyurethane resin, an epoxy carbonate resin, or a polyamide resin may be used. And a nut 2 such as an epoxy melamine resin, which is a washer base hex nut that clamps the steel structure 101 and the attachment plates 1〇2, 103 and locks the screw portion lc of the bolt 1. The nut 2 has a seat surface 2b having a smaller diameter than the width of the hexagonal surface. As shown in Fig. 3, the nut 2 is formed of a rust-preventing spray film 20 of an AI-Mg alloy in a comprehensive manner except for the inner screw portion 2a and the contact surface seating surface 2b on the side of the steel structure 10 1 . The rust-preventing spray film 20 of the nut 2 is formed by an arc spray method. The spacer 3' is disposed between the head of the bolt 1 and the spacer 4' between the elastic body 100 and disposed between the nut 2 and the elastic body 1〇〇. As shown in Fig. 3, the spacer 3 is formed of an A1-Mg alloy rust-preventing spray film 30 on the entire surface including the contact surface 3a on the side of the elastic body and the inner surface of the screw hole 3b. The spacer 4' includes an inner surface of the bolt hole 4b, and an rust-preventing spray film 40 of an Al-Mg alloy is formed on the entire surface of the contact surface 4a on the side of the elastic body 100. The rust-preventing spray coatings 30, 40 of the gaskets 3, 4 are formed by an arc spray method. -11 - 201231832 In the above-described configuration, the rust preventive spray film 20 is not formed in the screw portion 2a of the nut 2 and the seat surface 2b of the contact surface on the side of the clamp body 1 side, and the nut 2 is locked. In the case of the sliding surface of the nut 2 and the spacer 4, and the sliding surface of the screw portion 2a of the nut 2 and the screw portion 1c of the bolt 1, the rust-proof spray coatings 1 and 40 exist only in one of them. The face. Therefore, when the nut 2 is locked, the anti-rust spray coating 20 of the nut 2 and the anti-rust spray coatings 10 and 40 of the bolt 1 and the gasket 4 are not integrated on the sliding surface. When it is tightened, the gasket 4 disposed between the nut 2 and the elastic body 100 is tightened when the nut 2 is locked, and the sliding surface of the gasket 4 and the elastic body 1〇〇 is tightened. The anti-rust spray film 40 is not formed on the side contact surface 4a of the body 1. On the sliding surface, only one of the surfaces has the anti-rust spray film 1 〇 3b. Therefore, when the nut 2 is locked, the rust-preventing spray film 40 of the gasket 4 and the rust-preventing spray film 〇3b of the elastic body 100 are not integrated on the sliding surface. That is, when the shank is tightened, the sliding surface of the nut 2 is locked, and the rust-preventing spray film 20 of the nut 2 and the rust-preventing spray film 10, 40 of the bolt 1 and the gasket 4 are not integrated. Since the rust-preventing spray film 40 of the gasket 4 and the rust-preventing spray film 〇3b of the quilted body 100 are not integrated, the specific locking torque can be locked to the end. Therefore, when the clamp is tightened, the required axial force can be obtained when the lock is locked with a specific tightening torque. In addition, the screw portion 1c of the bolt 1 is sealed by a sealing treatment agent containing 1 to 10% by mass of paraffin wax, and the rustproof spray film 1 of the screw portion 1c of the bolt 1 is used. The surface of the crucible is a resin-based sealing agent in which the main component of the sealing treatment agent is fixed, and 1 to 1% by mass of paraffin wax. Therefore, when the screw portion 1c of the bolt 1 is locked to the nut 2 of -12-201231832, the friction between the bolt 1 and the nut 2 is reduced, and the required axial force can be obtained when locked with a specific locking torque. Further, in the case of the clamp of the present embodiment, the spacer 3 disposed between the head 1a of the bolt 1 and the clamped body 1 is formed with rust prevention on the contact surface 3a on the side of the clamped body 100. The spray film 30 is used, however, when it is normally locked by the elastic body 100, since the head 1a of the fixing bolt 1 is fastened and the nut 2 side is rotated to lock, since the contact surface 3a does not become a sliding surface, There will be no problems. Further, the gasket 3 may be formed in the same manner as the gasket 4, except that the blast preventing spray film 30 may be formed in addition to the contact surface 3a. Further, after the tightening is locked, the exposed surfaces are protected by the rust-preventing spray coatings 10, 20, 30, 40, 101b, 102b, 103b. In addition, the screw portion 2a and the seat surface 2b of the rust preventive spray film 20 are not formed in the nut 2, and the rust preventive spray film 40 is integrally adhered to the opposite surface side to obtain the rust preventive effect. Protection by the spray film 40. Further, the gasket 4 does not form the contact surface 4a on the side of the elastic body 100 of the rust-preventing spray film 40, and the rust-preventing spray film 〇3b on the opposite surface side of the rust-preventing surface is integrally bonded thereto. The rust preventive spray film 103b is protected. Further, in the case of the clamp of the present embodiment, the rust preventive spray film 20 is formed on the nut 2 by an arc spray method in which a film having a thick surface and a high adhesion force is formed, and the bolt 1 is formed to form a surface thickness. The rust-preventing spray film 1 is formed by a gas jet method or a plasma jet method of a fine film, and even if the nut 2 is rotated by an impact wrench or the like, the rust-proof spray film of the hexagonal corner portion of the nut 2 can be prevented. 20 peeling. On the other hand, since the surface of the film 〇 which is formed by the gas jet method or the plasma jet method of the screw portion 1 c of the bolt 1 is smooth, it is easy to lock the nut 2 . Further, in the case of the clamp of the present embodiment, the bolt 1, the nut 2, and the spacers 3, 4 are constituted. However, either or both of the spacers 3, 4 may be omitted. At this time, in the same manner, when the nut 2 is locked, the sliding surface of the nut 2 and the elastic body 100, and the screw portion 2a of the nut 2 and the screw portion lc of the bolt 1 are rustproofed. The coating film 1 〇, 40 is present on only one of the faces. Therefore, when the nut 2 is locked, the rust preventive spray coating 20 of the nut 2 and the rust preventive spray coating 1 of the bolt 1 are not slid on the sliding surface, and the same can be specified as described above. When the tightening torque is locked to the end, the required axial force can be obtained when locked with a specific tightening torque. Further, even if the contact surface 4a of the gasket 4 is integrated with the rust-preventing spray coating film 10 3b, the nut 2 and the gasket 4 are not integrated, so that the contact surface 4a of the gasket 4 is formed to prevent rust. There is no problem in spraying the film 40. Further, in the squeezing device of the present embodiment, the rust-preventing spray coatings 1 〇, 20, 30, and 40 are formed by the same Al-Mg alloy as the squeezing body 100, however, the squeezing body 1 can also be used. The anti-rust is sprayed with a film material and formed of zinc, aluminum, or an alloy thereof. [Example 1] [Axial force confirmation test] The axial force confirmation test of the clamp of the above embodiment was carried out. The test was carried out by using a bolt for sealing the pore sealing agent which changes the paraffin mixing ratio of the resin-based sealing agent to measure the tightening torque 値 and the axial force. -14- 201231832 4th to 7th, respectively, are mixed with 〇 mass%, 2.0% by mass, 3.0% by mass, and 5.0% by mass of paraffin waxed acrylic cerium oxide resin (eight water. y ΑΖシ一7 — (trade name): NIPPON PAINT Co., Ltd.) The tightening torque 螺栓 of the bolt subjected to the sealing treatment and the obtained axial force measurement result. Fig. 8 is a graph showing the tightening torque 螺栓 of the bolt which is sealed by the enamel resin varnish mixed with 1% by mass of paraffin wax and the obtained axial force measurement result. As shown in Fig. 4 to Fig. 8, when the bolt subjected to the sealing treatment with paraffin wax is used, the target axial force is achieved by the second tightening with a specific torque. Further, Fig. 9 is a comparison chart of the different paraffin mixing ratios obtained from the results of Figs. 4 to 8 (average 値) and the bolt locking torque 封 of the sealing agent and the axial force obtained. As shown in Figure 9, when different sealing agents are used, the mixing rate of the sarcophagus is changed, and the target axial force can be achieved with a specific locking torque of 2 times. [Example 2] (Adhesion test of coating film and sealing treatment agent) The adhesion test of the sealing treatment agent and the coating film which respectively changed the wax content rate was performed. The test was carried out in accordance with JIS K5600-5-6 C General Test Method for Coatings, Part 5: Mechanical Properties of Coating Film, Section 6 Adhesion (Cross Cutting Method).
