問題点があった。(Problems to be Solved by the Invention) Such adhesives do not allow excessive input in the peeling direction to the panel joints due to external factors such as collisions with protrusions, contact between cars, or collisions during the use of the car. If this occurs, cracking will occur at the interface between the panel member and the adhesive used for rust prevention, and if you cannot find a single crack when repairing the member, this area will become a bare member later. If left exposed, the rust-preventing ability is lost, and rainwater or water from car washing may enter through the joints, causing rust.

づくものである。(Means for Solving the Problems) This invention provides that when a cohesive failure type rust preventive agent is used at the joints of panel members, when the joints are subjected to excessive strain in the peeling direction, the rust preventive agent is completely destroyed. This is based on the finding that due to cohesive failure, the metal remains evenly in both parts, and the corrosion resistance of the parts is maintained.

、両者をほぼ同じ分量で使用するのが好ましい。Steel plate panels for automobiles are usually assembled after being pressed L71 and coated with rust preventive oil, so the panel joints are also coated with rust preventive oil in the same manner. Therefore, in this invention, in order to improve the adhesive strength on curved steel plates, 0 to 60 parts by weight of bisphenol A type and bisphenol F type epoxy resins, which are compatible with rust preventive oil (sulfur-based oil), are used. 1 Preferably bisphenol A type 60 to 40 parts by weight, bisphenol F type 40 to 6 parts by weight
The amount is 0 parts by weight and used as a single resin. Both types of bisphenol epoxy resins are equivalent in terms of physical properties and rust prevention properties, and are used together to adjust liquid properties, especially viscosity, and bisphenol A type is superior to bisphenol F type in terms of shower resistance. However, since the dischargeability is poor, it is preferable to use almost the same amount of both.

It is. In particular, dimer acid-modified epoxy resin gives flexibility to rust preventive agents and improves bendability, impact resistance, and peelability.

130 parts by weight of the rust preventive pigment is blended.The reason for this is: ``The rust preventive of this invention is originally required to be in a cohesive failure type. 1. Also, the rust preventive pigment is used to protect the steel surface of the panel from rust by blending it in the above amount.・The rust preventive pigment that contains the above ingredients usually contains a conductive pigment.

If the input in the peeling direction is smaller than the interfacial adhesive force between the panel 2 and the rust preventive agent 1, the interfacial adhesive force between the panel 8 and the rust preventive agent 1, and the cohesive force of the rust preventive agent l, it is a component of the rust preventive agent. The covering ring 8, which is based on the conductive pigment 7 and is integrally electrodeposited with the panel surface, maintains the rust prevention caused by the rust preventive agent at the panel joints. on the other hand,
If the input in the peeling direction is large, the interfacial adhesive force between panels 2 and 3 and rust preventive agent 1 is greater than the cohesive force of the rust preventive agent.
Furthermore, since it contains scale-like rust preventive pigments such as fine vermiculite, talc, and graphite (aluminum powder), complete cohesive failure occurs, leaving the rust preventive agent evenly on both parts. A resin component consisting of bisphenol A1 bisphenol F1 dimer-modified epoxy resin and reactive synthetic rubber, as well as rust preventive materials that chemically protect the iron base, such as iron oxide, zinc powder, zinc phosphate, zinc carbonate, and trizinc phosphate. Since the pigment 5 is included, sufficient rust-preventive power is maintained with only the rust-preventive agent remaining after destruction.
