Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispersing apparatus for dispersing a liquid compound containing a solid such as a pigment of a paint or ink, and more particularly, to a relatively hard solid such as bead carbon. The present invention relates to a dispersion apparatus capable of performing dispersion.

[0002]

2. Description of the Related Art A coating composition containing a solid material such as a coating or an ink is produced by, for example, a pre-kneading step of mixing a resin varnish and a pigment to obtain a paste, a ball mill using a paste obtained by the pre-kneading step. A dispersing step of obtaining a mill base in which the pigment is uniformly dispersed in a resin varnish by dispersing with a dispersing device such as a roll mill or a sand grind mill, and the mill base obtained by the dispersing step using a dissolver or the like as a solvent, a resin varnish, if necessary. It is manufactured through a dissolving step of mixing and dissolving with additives.

[0003] In recent years, basket mills have been used for the production of paints and inks because of the good workability that the above-mentioned dispersion step and dissolution step can be performed simultaneously.

[0004] In this basket mill, a stirring tank is filled with a liquid (hereinafter, referred to as a "compound") in which a pigment, a solvent, a resin varnish, and if necessary, additives are mixed. A stirring blade is attached to the tip of a stirring shaft provided to reach the composition from the above, and the stirring blade is rotated by a rotary drive device through the stirring shaft, whereby the mixture between the compounds is removed. Pigment particles (secondary particles) aggregated by shear stress are disintegrated into pigment particles alone (primary particles), and a solvent, a resin varnish, an additive, etc. are mixed to disperse the pigment particles in the liquid, A metal sheet material in which a number of small holes are formed in the side wall and the bottom wall on the outside of the stirring blade,
Alternatively, the solid material in the mixture is surrounded by a basket (cage) made of a fine mesh wire mesh, and a dispersion medium such as a glass ball, a steel ball, and a ceramic ball is put into the basket and the stirring blade is rotated. Large particles are crushed by the grinding and mixing action in the basket to become finer, and the finely divided pigment particles flow out of the small holes and meshes on the bottom wall and side of the basket and convection in the stirring tank. Then, it flows into the basket again from above the basket and is further finely crushed and dispersed in the composition (for example, JP-A-60-122033, JP-A-61-293536).
Reference).

In such a basket mill, the composition dispersed in the basket flows out through small holes formed in the bottom and side walls of the basket, and the composition flowing out below the bottom wall of the basket is dispersed in the basket bottom. By the rotation of the liquid flow vanes provided below the wall, convection occurs above the basket, and the liquid flows into the basket again from above to disperse.However, solids such as secondary particles of the pigment in the compound are not contained in the liquid. In this case, since it is a heavy material, a considerable amount thereof is not dispersed and falls directly from the small hole in the bottom wall of the basket to the bottom of the stirring tank. That is, since the dispersion medium charged into the basket is collected around the basket side wall by the rotational centrifugal force generated by the rotation of the stirring blade, at least the compound around the stirring shaft is not dispersed at all in the basket. Since it tends to flow out of the small holes in the bottom wall directly below the basket and settle down below the stirring shaft, it is still a major issue how to improve the dispersing effect in a short time in consideration of these factors. there were.

[0006] Further, in the dispersing apparatus provided with a basket having a large number of small holes as described above, clogging tends to occur due to agglomerated pigment particles in the composition. When the composition containing pigment such as bead carbon formed to have a particle size of about 1 mm is dispersed, the pigment formed in the basket without dispersing the pigment such as bead carbon is dispersed. The clogging of the holes results in the clogging of the basket by the bead carbon, which prevents the composition from circulating in and out of the basket. For this reason, in a conventional basket mill, it is impossible to disperse a compound containing a solid such as a pigment, such as a bead carbon, in which primary particles are strongly agglomerated and secondary particles are hard and are not easily loosened.

[0007] In order to solve such a problem, a dispersing device in which the bottom wall of the basket is formed by a bottom wall having no small holes and only small holes are formed in the side walls, and a small hole of the dispersing device is provided. A side wall flat plate and a plurality of gap plates shorter than the side wall flat plate in the circumferential direction of the side wall are alternately overlapped with each other, and are formed by slits formed by side wall flat plates facing vertically and gap plates facing the circumferential direction of the side wall. A dispersion device having small holes has already been filed by the applicant of the present invention (Japanese Patent Publication No. Hei 8-17).
No. 930).

[0008]

Problems to be Solved by the Invention
In the dispersing apparatus described in Japanese Patent No. 930, the residence time of the compound inside the basket is increased by using the bottom wall of the basket as described above, which is shorter than the conventional basket mill. Dispersion of the formulation can be performed.

In the case of a dispersing apparatus having slit-shaped small holes formed in the side wall of the basket, even if it is used for dispersing a compound containing a pigment having a high hardness such as bead carbon and coarse particles. Small holes in the basket are difficult to clog,
Even such a composition can be dispersed.

However, when a composition containing beaded carbon or the like is dispersed by the above-described dispersing apparatus, it takes a long time to reduce the solid content of the pigment such as beaded carbon to a desired particle size in the formulation. If the formulation is heated by frictional heat due to long-term dispersion and the solvent etc. in the formulation evaporates, the quality of the product will change and the raw material will be lost during the process. It melts into the atmosphere of the working environment and deteriorates the working environment.

Further, the black paint obtained by the above-mentioned conventional dispersing apparatus has a low shearing force, and thus lacks the depth of color.

On the other hand, the above-mentioned ball mill in which a pre-kneaded paste is put into a cylindrical drum together with a dispersion medium composed of spheres such as steel or alumina and the drum is rotated to disperse the paste, or a plurality of rolls having different rotation speeds In the case of performing the dispersion by the above-described roll mill in which the paste that has been pre-kneaded is passed and the dispersion is performed by the shearing force given to the paste by the speed difference between the rolls, a black paint having a deep color is manufactured using bead carbon as a raw material. be able to.

However, when the dispersion is performed using the ball mill or the roll mill as described above, in order to obtain the final paint or ink, the mill base obtained by the dispersion step using the ball mill or the roll mill is used. In addition, it is necessary to go through a dissolving step of dissolving in a resin varnish, a solvent, and an additive using a known dissolver or the like, and in the above-described ball mill, it takes a long time to disperse, and the dispersion medium and the inner wall of the drum are used. There is a problem that the noise generated by the collision with the device is remarkable and noise reduction measures are required when installing the device, and the cost for maintenance of the surrounding environment increases.

Further, in the above-mentioned roll mill, although there is less problem such as generation of noise as compared with the above-mentioned ball mill, it is difficult to disperse a paste containing solid matter such as bead carbon having high hardness. Need to be rotated strongly at high pressure, the drive source such as a motor becomes large and not only makes the device large and expensive, but also consumes power to obtain high output rotation of the roll. Is increased.

Therefore, the object of the present invention has been made in view of the above-mentioned disadvantages of the prior art, and is similar to a basket mill and a dispersing device disclosed in Japanese Patent Publication No. H8-17930. Dissolution can be performed simultaneously,
Therefore, the workability is good, and the work of dispersing the compound containing a solid material having high hardness such as bead carbon can be performed in a short time, and the shearing force or the force capable of producing a black paint having a deep color can be obtained. An object of the present invention is to provide a dispersing device having an extremely high impact attrition force.

Another object of the present invention is to provide the above-described dispersing apparatus, in which the composition filled in the stirring tank is convected well, and the solids in the composition are removed from the bottom of the stirring tank. It is an object of the present invention to provide a dispersing apparatus having a structure capable of preventing sedimentation in a basket and being able to be favorably introduced and dispersed in a basket.

Further, another object of the present invention is to provide a mechanism capable of preventing the heating of the compound in the above-mentioned dispersing apparatus, thereby preventing volatilization of a solvent or the like in the compound and preventing a change in the quality of a product or the like. It is an object of the present invention to provide a dispersing apparatus capable of preventing a raw material loss during a process and deterioration of a working environment.

Further, in the embodiment shown in FIG.
May be provided in the opening 38.

The operation of the entire apparatus including the dispersion apparatus of the present invention configured as described above will be described.

A liquid compound 65 comprising a solid such as a pigment such as a paint or ink, a resin varnish, a solvent, and an additive added as necessary is filled in the stirring tank 60, and The dispersing apparatus main body 10 of the present invention is arranged in the tank as described above.

When the lift valve 57 of the lift device 50 is opened,
A cylinder (not shown) in the elevating device main body 51 is operated, and as the elevating shaft 53 is raised, the rotary drive mechanism 11 is guided by the guide shaft 54 to ascend, and the dispersion provided at the tip of the rotary drive mechanism 11 is provided. The basket 20 of the apparatus body 10 also moves up. In this state, the stirring tank 60 loaded with the compound 65 is moved to a predetermined position below the basket 20, and the lowering valve 58 of the elevating device 50 is opened to move the basket 20 of the dispersing device body 10 to the stirring tank. 60
Into the composition 65.

When the motor 41 of the rotation drive mechanism 11 is driven, the rotation shaft 12 of the dispersion apparatus main body 10 is driven to rotate via transmission means such as a V-belt (not shown). The rotation speed of the rotating shaft 12 is adjusted by the above method.

The rotation of the rotating shaft 12 causes the basket 20 to rotate.
The dispersion pins 14 (141a, 141b, 14
2) rotates in the basket 20 to stir the dispersion medium 37 in the basket, and the composition 65 in the stirring tank 60 is moved by the convection generated by the liquid introduction blade 18 provided on the rotating shaft 12. It is introduced into the basket 20 through an opening 38 provided in the lid plate 22 on the upper surface of the basket 20.

In the case of having the additional dispersion mechanism of FIG. 8,
The fixed and movable pins 73 and 74 pass through the opening 38 by a pre-dispersion action of grinding or polishing the compound by the impact grinding force, or in the embodiment of FIG. The compound 65 introduced into the basket 20 is first supplied to the primary preliminary dispersion chamber 2 in the basket 20.
01a collides with the dispersing medium 37 stirred by the dispersing pins 141a, and is pre-dispersed by the grinding force and shear stress due to the collision between the dispersing media 37, passes through the dispersing medium 37, and passes through the second dispersion chamber. 201b.

The compound 65 introduced into the secondary preliminary dispersion chamber 201b is similarly dispersed by passing through the dispersion medium 37 stirred by the dispersion pins 141b, and is also passed through the dispersion medium 37 to finish. It is introduced into the dispersion chamber 202,
Dispersion medium 3 accommodated in secondary preliminary dispersion chamber 201b
7, the weight of the dispersion medium 37 accommodated in the primary preliminary dispersion chamber 201a is also added, so that the dispersion medium 37 stirred in the secondary preliminary dispersion chamber 201b is The resulting impact force is enhanced, so that the composition pre-dispersed in the primary pre-dispersion chamber 201a is further finely dispersed in the secondary pre-dispersion chamber 201b, and the finishing dispersion chamber 202 which is continuous therebelow. Introduced within.

The dispersion medium 37 disposed in the finishing dispersion chamber 202 is composed of the primary preliminary dispersion chambers 201a and 201a.
In addition to the weight of the dispersion medium 37 disposed in the next preliminary dispersion chamber 201b, the impact force generated when the dispersion medium 37 is stirred is far greater than the impact force in the preliminary dispersion 201, Therefore, by passing through the finishing dispersion chamber 202, the solid matter in the compound 65 is almost completely dispersed in a short time.

As described above, in the dispersing apparatus of the present invention, the primary preliminary dispersing chamber 201a, the secondary preliminary dispersing chamber 201b corresponding to the dispersing chamber formed in each basket in the conventional dispersing apparatus, and the finishing Since the dispersion chamber 202 is formed continuously in the vertical direction, the processing capacity is remarkably improved as compared with the basket of the conventional dispersion apparatus, and the dispersion medium 37 accommodated in the finish dispersion chamber 202 is provided. On the other hand, since the weight of the dispersion medium 37 disposed in the primary pre-dispersion chamber 201a and the secondary pre-dispersion chamber 201b is added, the dispersing ability is dramatically improved.

Therefore, the solid matter in the blend 65 is finely crushed and dispersed as compared with the conventional dispersing apparatus only by passing once through the basket. As a result, even a composition containing a solid substance having a high hardness such as the above-mentioned bead carbon can be dispersed well in a short time, and a black paint having a deeper color can be obtained by dispersing the composition containing bead carbon. Can be manufactured.

As described above, since the basket 20 of the dispersing device is formed in a vertically long shape capable of forming three chambers therein, the amount of the dispersing medium accommodated therein also increases, and Although the amount of heat generated upon stirring also increases, a cooling medium such as cooling water supplied from a cooling medium supply source (not shown) passes through the lid plate 22 and the cooling medium through the cooling medium flow path formed in the rod 13. Since the heat is circulated in the hollow chamber 44 formed in the upper side wall 241, the heat generated during the stirring operation is circulated in the lid plate 22 and the hollow chambers 40 and 44 formed in the upper side wall 241. The solvent is suitably cooled by the cooling medium 37, and therefore, the volatilization of the solvent caused by the compound 65 being excessively heated, the deterioration of the quality of the product due to the volatilization, the loss of raw materials in the process, the deterioration of the working environment, and the like are preferably performed. Can be prevented.

The solid matter such as the pigment dispersed in the solvent, the resin varnish, and the additive in this manner is centrifugally generated by the rotation of the dispersing pin 14 to form a small hole 35 formed of a slit provided in the lower side wall 242. It passes and flows out of the basket 20. At this time, since the solids in the compound 65 are substantially completely dispersed, there is no clogging of the small holes 35, and even a compound containing a solid having a coarse particle size can be satisfactorily dispersed.

After passing through the slit 35, the basket 2
The formulation 65 that has flowed out of the chamber has a spill effect or
The liquid is convected upward by a liquid flowing blade 47 provided below the stirring tank and away from the basket 20, and flows into the basket 20 again.

Among the solid particles dispersed in the basket 20, particles larger than the width of the slit 35 determined by the thickness of the gap plate 28 cannot pass through the slit 35, and thus are further finely dispersed in the basket 20. Is done. Therefore, by adjusting the thickness of the gap plate 28, the dispersion state can be adjusted according to the type of the compound.

After the dispersing process is completed as described above, the motor 41 is stopped, the ascending valve 57 is opened, and the dispersing apparatus main body 1 is opened.
The basket 20 of 0 is raised from the stirring tank 60, and then the stirring tank 60 is unloaded. When the inner surface of the bottom plate 39 is formed in a tapered shape which is inclined downward and outward, the basket 20 is filled with the compound 65 in the stirring tank 60.
When the product 65 is taken out of the basket 20, the composition 65 in the basket 20 is more efficiently drained, so that the composition 65 is not wasted and is effective.

Before dispersing another type of formulation 65,
The dispersing apparatus main body 10 is completely washed, and the subsequent dispersing process is performed in the same manner. The dispersing medium 37 in the basket 20 can be easily removed from the dispersing medium extracting hole 31 of the bottom plate 39, and the dispersing medium 37 can be separately washed.
