Abstract

PURPOSE:To make two liquid hardenable paint applicable by jetting main agent and hardener through a separate spray gun, and mixing them on the way of injection and in a painted film, and using air for a control system. CONSTITUTION:Main agent paint 5 is filled up in a main agent paint tank 4, and hardener 14 is filled up in a hardener tank 13. Next a pump 3 is actuated to pressurizedly store the main agent 5 in a main agent accumulater 9, and air is supplied from a compressor 31 into an air accumulating tank 17. Next the air is supplied from the tank 17 to the tank 13 and a gun opening and closing conroller 23. A gun operating valve 24 is operated to open a main agent spray gun 12 and a hardener spray gun 16 through the controller 23 for jetting the main agent 5 and the hardener 14. In addition, the injection timing of the main agent 5 and the hardener 14 is regulated by the controller 23 and the valve 24, and their mixing ratio is regulated through pressure and the diameter of an injection nozzle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small marking line construction machine which is constructed by using a paint of a type which cures by mixing two liquids of a main agent and a curing agent.

[0002]

2. Description of the Related Art A coating material conventionally used as a marking line is a solvent type paint which is hardened by vaporization of a volatile solvent or is melted by heating and is cooled to an ambient temperature because of its easy handling during construction. It was a material mainly composed of a melt-type paint that was cured by the above.

Recently, two-component curable paints have attracted attention for the purpose of improving the durability of lane markings, shortening traffic regulation time, and improving high-speed workability.

However, a two-component curable paint is used by mixing a main component and a curing agent in a fixed ratio, but in the case of a lane marking paint, it is necessary to increase the curing speed for reasons such as shortening of traffic regulation and so on. Since the (time from mixing to starting curing) becomes extremely short, there is a problem that the paint solidifies inside the mixer of the device or in a place where there is little convection in the pipe after that. Since it occurs and continuous work cannot be performed for a long time, it is currently used only for very special lane markings.

[0005]

DISCLOSURE OF THE INVENTION As described above, in a device for constructing a marking line with a paint that uses two liquids of a main agent and a curing agent, it has been difficult to put it into practical use. It is intended to provide a small marking line construction machine using a practical two-component curable paint by devising the method and the coating conditions.

[0006]

[Means for Solving the Problems]

1. Air-free injection of the main agent and curing agent with separate spray guns, and mixing and curing in the middle of spraying and in the coating film prevents the coating from solidifying before injection and also mixes the main agent and curing agent. Make sure and completely eliminate uneven solidification after application.

2. The main agent was applied by airless spray injection using the same airless pump and spray gun as the conventional paint application device, and the curing agent was applied in a separate accumulating air tank. The pressure is applied from above the curing agent tank with air, and the curing agent is pressure-fed by the pressure, and is sprayed by airless injection into the main agent spray through the spray gun or onto the main agent application surface.

3. Regarding the mixing ratio of the main agent and the curing agent,
First, the application conditions of the main agent are determined, and the amount of the curing agent adapted to this is adjusted by adjusting the air pressure and the spray gun diameter.

4. The opening and closing of each spray gun for the main agent and the curing agent is performed by operating the controller at the same time or at a fixed time difference, thereby airlessly injecting the curing agent immediately after the application of the main agent injection or after an appropriate time to prevent uneven curing.

5. The spray gun is opened and closed, and the controller is air-operated so that the power source such as the battery is eliminated. By the above means, it is possible to provide an inexpensive small-sized partition construction machine using the two-component curable paint.

The present invention has the following effects.

Since the main coating material and the curing agent are respectively airless sprayed and mixed on the road surface after spraying, the trouble due to solidification in the spraying device has been completely eliminated.

The injection amount that determines the mixing ratio can be easily adjusted by adjusting the injection nozzle diameter and pressure of the spray gun, and the injection timing can also be easily adjusted by combining the gun opening / closing controller and the gun opening / closing operation valve. .

Since the on-off valves used in each part are all of the air type, no battery is required,
It can be made smaller and lighter.

Further, since the base material coating material and the curing agent are sprayed by airless, both the base material coating material and the curing agent are sprayed in a band shape, and the two can be mixed evenly after coating.

Since the two-component curable coating material is used, it is possible to efficiently construct road marking lines by improving durability, shortening traffic regulation time, improving high-speed workability, and the like.
