Problems solved by technology

[0010] However, in the prior art described above, since the two components that are mixed and start to solidify remain in the mixer, the composition mixed in the mixer will solidify if it is not used for a long time, so there is a problem. The problem of not being able to start coating again after changing the mixer
In order to solve this problem, there is also a method of discarding the remaining components mixed in the mixer before solidification, but in this case, a large amount of excess components may be consumed
In addition, although there is a method of introducing an organic solvent into a static mixer and cleaning it, sometimes a large amount of solvent is required, or the organic solvent smells during and after cleaning, and the disposal method of the solvent becomes a problem.

Embodiment approach

[0031] Figure 1 to Figure 6 An embodiment to which the two-dose composition discharge device of the present invention is applied is shown. Here, a case where the two-dose type composition discharge device is a two-dose type adhesive discharge device and the fluid is air will be described.

[0032] Hereinafter, embodiments of the present invention will be described based on the drawings. figure 1 It is a schematic front view of the appearance of the two-dose composition discharge device. The composition of the cleaning device includes: a communication device 1, which is installed with a fixed static mixer; a static mixer 2; a mixer holder 3, which is used to connect with the communication device 1; check valves 4A and 4B, which are used to prevent compression The air counterflows to the composition introduction pipeline, and the compressed air is used to clean the static mixer; valves 5A and 5B, which are used to control the introduction of the composition. The valve may, f...

Embodiment 1

[0054] For the two-part adhesive, a two-part mixed type acrylic adhesive was used. It consists of a first agent and a second agent, wherein the first agent contains a curing agent and an acrylic monomer, and the second agent contains a curing accelerator and an acrylic monomer. Figure 1 to Figure 6 The shown double-dose adhesive discharge device applies the double-dose adhesive to the adherend. After the coating is finished, the static mixer 2 is cleaned with compressed air. The pressure of compressed air is 0.5MPa. After cleaning, the inside of the static mixer 2 was checked, and as a result, no two-part adhesive component remained in the static mixer 2 . In addition, no adhering agent components remained in the communicating vessel 1 .

[0055] As described above, the two-dose type composition discharge device according to the present invention can reduce the loss of the composition due to discarding the composition and completely eliminate the use of organic solvents, s...

Abstract

Provided is a device for dispensing compositions of two or more agents that can significantly prevent waste of the compositions for flushing and that does not need an organic solvent for cleaning. The composition-dispensing device for coating with compositions of two or more agents is provided with a supply path for each component of the composition, a static mixer that is connected to the outlet of the supply path for each component, a valve disposed in the supply path of each component for controlling the introduction of each component into the static mixer, and a supply path for air for cleaning that is downstream from the valve and is connected to the supply path for each component via a check valve.

Description

technical field [0001] The present invention relates to a composition discharge device which mixes two or more compositions with a static mixer and discharges them. In addition, the present invention also relates to a cleaning method of the composition discharge device. Background technique [0002] As an application device for a two-dose composition, there are known discharge devices that mix and use two doses immediately before use (Patent Documents 1 to 3). [0003] The above-mentioned device is supplied to a static mixer while measuring the prescribed amounts from tanks containing the first and second doses of the two-dose type, and the two doses are mixed in the mixer and applied to the adhesion site from the nozzle.
