Generally, synthetic resin materials such as urethane or epoxy are applied to interior and exterior walls of buildings and ships for improving aesthetics, waterproofing heat insulation, etc., and various methods and apparatuses for applying such synthetic resins to walls are developed. The situation is being used.

In particular, the synthetic resin material used as described above is divided into one-component and two-component according to the form of the material. In the case of the one-component synthetic resin, it is convenient to store and use only by applying one liquid synthetic resin. There is a problem in that the drying time is long, the working efficiency is lowered to be solidified by natural drying, and where the rapid application effect is required due to the deformation of the coating due to the external temperature difference.

In the case of a two-component synthetic resin, it is composed of a liquid main body in which a solid synthetic resin is formed after solidification, and a curing agent which solidifies the main body by a chemical reaction. The main body can be cured quickly by the reaction, so that the coating effect, heat insulation, heat insulation and waterproof effect can be obtained, but the main material and the curing agent must be mixed in an appropriate ratio, and the application must be performed quickly before the mixed main material and the curing agent solidify with each other. There was an inconvenience.

In order to apply the two-component synthetic resin, a two-component injector for mixing the main body and the curing agent in an appropriate ratio and spraying at the same time has been devised. Not only there was a problem, there was a problem that the maintenance of the painting device is difficult.
