There are methods such as the air-filled stock method and the 9° independent wall microencapsulation method. However, using this manufacturing method, it is possible to microcapsule substances that are liquid or lose their stickiness at room temperature, such as water, bath additives, starch syrup, dipping agents, adhesives, etc. There are disadvantages in this case: That is, in the methods of / to j, when a core substance such as a self-containing substance is dispersed in a dispersion medium, if the core substance has stickiness, the VC is agglomerated with core substance particles. Further, it is necessary to adjust the wetting between the core material and the molecule solution and the specific gravity, and the drawing is done on the surface @1, and the properties of the finished capsule are not good. Also, method 6 makes micron-order capsules! 1llVC<, production efficiency is also low. Furthermore, although the method described in 5.7.8 is used to encapsulate toner, it is difficult to produce capsules with uniform film thickness and complete coverage, and in the case of highly adhesive substances such as toner, agglomeration occurs. invite. In addition, since methods 1 to 8 use water or organic solvents, it is not possible to encapsulate the reacting core substance soaked in water or organic solvents, and post-treatment of the organic solvents is troublesome. In order to extract the capsules as a powder, drying is necessary, which poses the risk of fire and explosion. Furthermore, in method 9, if the core material is a soft material, a large amount of wall material will be mixed into the core material, and capsules are more likely to become a mixture.

Examples include plastic fine powder such as 11L lead, aluminum powder, ceramic fine powder, polyethylene 17, nylon, methacrylic powder, etc., phytic acid and its metal salts, starch, and fine powder obtained by surface modification of these fine powders, but the core material The one that has no affinity with is selected. 'Cj K If the liquid r1 has a viscosity of about 100 centiboise, fine powder that has an affinity for it must be absolutely avoided. That is, if the core substance is hydrophilic, it is necessary to select a hydrophobic fine powder, and if the core substance is hydrophobic, it is necessary to select an X-hydrophobic powder. In addition, a fine powder with a particle size smaller than the diameter of the powder to be freeze-pulverized, preferably less than 10% is used.Next, regarding microencapsulation, do.

~to seconds. In particular, when this type of stirrer is used, freezing and pulverization can also be carried out within this apparatus J', which is advantageous in terms of the process. 1++, a ball mill, a cutter mixer, an attritor, etc. can also be used for mixing and stirring. The temperature during stirring is about the same as the temperature during freeze-grinding, and in order to prevent temperature rise due to frictional heat, fii'
However, it may be necessary to continue cooling by using a coolant such as nitrogen dispersion in the stirrer. In addition, the mixing ratio of the core material powder and the fine powder is determined depending on the shape of the core material powder.If the powder is spherical, the amount of fine powder may be small f, j-, but it is usually l-L core material.

0,'+i101;parts]L. Furthermore, the particle size of the obtained microcapsules is determined by the particle size of the core material powder and the film thickness VC of the fine powder, so it can be set to any value depending on the freeze-pulverization conditions, the mixing ratio of the core material and the fine powder, and the mixing and stirring conditions.
Microcapsules with an average particle size of /~/, !00 μn1 can be obtained.

That is, the core material powder is coated with a relatively fine powder and then coated with a polymer film by a conventional microencapsulation method. In this case, the compatibility of the capsule with the polymer film and the polymer film solution must be taken into account. For microcapsules coated with hydrophilic fine powder, microencapsulation using a water-soluble polymer is suitable, and a coacervation method using gelatin can be used. Hydrophobic 11: For microcapsules V made of fine powder, the coacervation method from a bath medium and the microencapsulation method using a hydrophobic polymer (t) are effective.

好ましい。Note 1. The material has a high viscosity, and the shape retention of group microcapsules is excellent and the stability is good, so in the case of a low viscosity core material, VC is a filler and a thickening agent. It is preferable to add a gelling agent or the like in advance to thicken or gel.

よくしたかつて製造コストが著るしく低いものとなる。The manufacturing method of such microcapsules VC, 1:iL is to freeze and crush the core material to powder, add fine powder to this, mix and stir under low temperature expansion. Because of this, there are very few particles;
By efficiently inspecting the materials, the deterioration of the performance of the microcapsule core can be minimized due to the powder.In addition, there is no loss of core material or fine powder during the manufacturing process. Microcapsules can be formed with a yield of 100 cm, and step 75
It can be produced in a short time with a simple process, and the production cost is significantly lower than in the past when only a stirrer was required for production equipment.

利点を４１する。[Example 5] Microcapsule powder 10 obtained in Example 4 VC1
The powder was mixed with phida 2 VCN'J by adding 1 tbsp of 0.0% vinegar to incorporate the above powder on the coacervate surface. After further cooling this dispersion, 30% formalin/T
Ll! Then add VC10% NaOH water to adjust the pH to 9, and then raise the temperature to 50°C at a heating rate of 7°C/min.
When the mixture was heated to a temperature of 100.degree. C., double microcapsules were formed in which the blush surface of the microcapsules was coated with gelatin. When this double microcapsule was added to Utami-dou IV1, it had excellent shape retention and strength! 1. Microcapsule powder with good IJ properties was obtained. 1. As explained above, the method for producing microcapsules of the present invention, when made into powder, always
(The powder melts the core material, which is a material that becomes a lump or agglomerates and cannot maintain its powder form.)
Since it is frozen at a low temperature that does not cause agglomeration, pulverized, and then mixed and stirred with fine powder at this temperature, it is possible to freeze the material at a low temperature that does not cause agglomeration, and then mix it with the fine powder at this temperature. Substances that are immersed in water or organic solutions or that are compatible with these can be used as core substances, and these core substances can be extremely f+i) with a simple process operation, in a short period of time, with a yield of ioo%. It can be made into microcapsules, and can be used for adhesives, adhesives, paints, toner, etc. In addition, compared to conventional methods, no water or organic solvents are used during production, so there is no need for drying or wastewater treatment, and the safety of chestnut production is high. It has the advantage that microcapsules can be easily manufactured, and microcapsules can be manufactured with a wide variety of 1-I characteristics.
