られている。The vehicle has been strengthened by reinforcing its joints with a reinforcing plate, but recently, a method called weld bonding, in which an adhesive such as epoxy resin is applied to the adherend and then spot welding is often used. ing. In addition to ensuring high strength, this method also makes it possible to reduce the weight of the vehicle body by omitting the reinforcing plate. However, when performing spot welding, a spark of welding may fly to the protruding adhesive and the adhesive may burn, and the adhesive may lose its adhesive function. In order to prevent burning, a small amount of adhesive may be applied so that the adhesive does not stick out from the adherend, but the adhesive strength and the waterproof effect will be reduced. Therefore, a technique for making the adhesive flame-retardant is required.
