2. Description of the Related Art The above-mentioned two-component reaction-curable epoxy resin or two-component reaction-curable urethane resin has a very high liquid viscosity in a low temperature region or a normal temperature region and should be mixed.
The liquid has the characteristic that there is a difference in viscosity at the same temperature,
In addition, unless the two liquids are mixed in an accurate ratio and mixed sufficiently, a curing failure due to a reaction failure will occur.
Construction difficulty is high when forming the resin floor layer and the like.

Therefore, when a resin floor surface layer or a resin waterproof layer is formed by the two-component reaction curable resin agent, for example,
Unlike ordinary paint coating, it is not possible to apply a simple supply coating method in which a large amount of a mixture of the main agent and curing agent is sprayed with a spray gun. Weighed in the main agent and curing agent, mixed them by manual stirring, and let them react, remove the mixture to the floor surface, etc. and finish it by hand trowel, finish each small area, and repeat the work one by one to get the required area. Is manually mixed and applied on the resin floor layer.

The conventional manual mixing and feeding method described above is extremely poor in work efficiency because of the manual work from heating and mixing of the main resin component and the curing agent to the coating. Not suitable for high productivity of construction,
Since there is naturally "work variation" due to manual work, the occurrence of defective curing due to poor mixing and the occurrence of defective trowel finishing due to differences in operator skills are inevitable, and a homogeneous high-quality resin layer is formed. There are difficult quality problems.

Further, since such manual work is easily tired and, in addition, it is often performed at a high place, there is a problem that the work strength is high and skill is required. The present invention solves the above-mentioned problems of the prior art, makes it possible to form a high-quality floor surface layer / waterproof layer by simply and efficiently supplying and applying a mixture of a main agent and a curing agent to form a two-component reactive curable resin. The present invention provides an agent mixing and applying apparatus.
