200819470, * IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to fine particles which are highly controlled in particle size, and a resin composition using the same. [Prior Art] First, an attempt is made to contain fine particles in a resin or a resin composition used for various purposes, and to enhance the properties of the resin or resin composition, and to be useful or useful. At the same time, optical resin materials for optical applications such as liquid crystal displays (LCDs), plasma display panels (cracks), electroluminescent displays (ELD), transmissive screens, and touch panels are similarly performed. For example, a resin film (sheet, plate) for imparting light diffusibility and anti-glare glare resistance is used for opticals containing microparticles composed of organic temporary materials... A resin composition is used as a raw material. ;,,,: In recent years, the image as described above has become more and more written or contains... In the field of clothing, there is a tendency to Up/Way, for the surrounding technology = seeking, "Poetry, Shouting (four) lines with other materials (resin or /, his additives), a wide range of research on the mechanical properties of the U particles themselves and the improvement of the pre-study characteristics. Also, for iso-optics It is made of resin film or liquid crystal. The text is 5 hai., the spacer for the L-shell is micro+ vertical; plus the above required characteristics, it is also expected that the particle size distribution is narrow, coarse and small, and the amount is small. When the spacers are widely used in the wide, and/or uncles, it is difficult to hold the liquid as a liquid crystal display element, and it is difficult to keep the thickness of the liquid crystal in a uniform manner. The stator will cause damage on the surface of the film, or the coarse particles may be directly observed. In the case of the microparticles 2226-9085-PF; Ahddub 5 200819470 . . , it is a cause of reducing the display quality of the image display device. For example, Patent Document 1 showing microparticles for optical use, according to the particle Manufacturing method, available according to The particle size distribution of the intended use is extremely sharp in particle size distribution. Moreover, in the patent reading 4, the coarse particles will reduce the display quality of the display device, and the disadvantage of the optical film is reduced, and the average particle size is reduced. Particles of the particle size of the size of the diameter: The method for producing the fine particles (Patent Document 2) is proposed to use a method of removing the coarse particles by the emulsion treatment of the fine particles in the state of the gel or the dispersion. Patent Document 3 and 4) [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A-2005-309399 [Patent Document 3] JP-A-2005-309399 (Patent Document 3) 4] 曰本特开2〇〇4_1 91 956 [Invention] However, as in Patent Document i, it is difficult to highly control the particle size distribution in the synthesis stage of fine particles, and also, as in the patent document W According to the fingering, even if the particle size distribution is managed in the dry circumference of the better pregnant soil, there is a large particle which is largely separated from the average particle size, which may cause a decrease in the mouth opening or a lack of optical film. Therefore, it is difficult to obtain fine particles which sufficiently satisfy the requirements of the above-mentioned patent documents 2 to 4, from the viewpoint of improving the visibility and productivity from the viewpoint of improving the visibility of the coarse particles. The present invention has been made in view of the above circumstances, and its object is to provide a method for reducing the inclusion of coarse particles of optimum particle size (IV) low-level particles, 2226-9085-PF; Ahddub 6 200819470 and the manufacturer of the related particles. And the composition of the resin and the resin composition containing the fine particles. The fine particles of the present invention which solve the above-mentioned problems are those in which the coarse particles having a particle diameter of 2 times or more of the average particle size are ι or less. The fine particles are preferably an organic-inorganic composite containing an organic polymer skeleton and a polyoxo-oxygen skeleton.制造 The method for producing fine particles of the present invention, characterized by comprising a step of grading a solid concentration of 0.5, a mass%, a B-type viscosity 〇 5 to 2 〇 mPa.*s, and a fine particle dispersion; The step of drying and pulverizing the powder microparticles containing water in an amount of from 〇·5 to 2% by mass; and the step of drying the above-mentioned powder microparticles in eight grades. In this way, by processing the raw material (fine particle dispersion, powder) having specific = in combination with wet classification and dry classification, it is possible to more effectively reduce the particle size from the large particle of the appropriate range or Tiny particles. The present invention also includes an optical film comprising the above-mentioned fine particles and a coating composition comprising the resin composition, and an optical film (light-diffusion film, anti-glare) obtained by coating the coating composition on a substrate. A film or the like having a concavo-convex shape on the surface). The U particles of the present invention reduce the content of coarse particles having a particle size out of the appropriate range to a low level. Further, according to the method of the present invention, the amount of fine particles can be reduced while the wire is controlled to be separated from the coarse particles of a suitable range. Therefore, it is considered that the molded article obtained from the resin composition containing the particles of the present invention is difficult to produce defects from coarse particles. Moreover, since the content of fine particles can also be reduced, it is considered that the transparency of the resin itself is not hindered. 2226-9085-PF; Ahddub 7 200819470 * Sex. The fine particles of the present invention are particularly suitable for an optical resin composition, a light-diffusing film obtained from the sap composition, an anti-glare film, and then a light-diffusing sheet comprising the fine particles of the present invention, which exhibits excellent optical characteristics. By. [Embodiment] The fine particles of the present invention are characterized in that the coarse particles having a particle diameter of twice or more the average particle diameter are 1 000 pieces/〇 5 g or less. / The microparticles used in the field of optics, which contain coarse particles with a particle size that deviates from the appropriate dry circumference, cause damage on the surface of the film, or it is easy to visualize the defects of the particles. In particular, according to the study by the present inventors, it is confirmed that the above phenomenon becomes remarkable when fine particles having a particle diameter of twice or more the average particle diameter are present (increased). The coarse particles having a particle diameter of 2 or more times the average particle diameter are preferably 5 Å / 〇 52 or less, more preferably 0.5 g or less, and further preferably 1 〇〇 / 〇 5 以下 or less. It is best to use 50 / 0. 5g or less. * In addition, when the amount of coarse particles is within the above range, and the number of coarse particles having a particle diameter of 2.5 times or more of the average particle diameter is 5 〇 / 〇 5 g or less, 'when used for optical use' is more difficult to produce. Bad from coarse particles and good. More preferably, it is preferably 30 or less. 5 § or less, and further preferably 1 〇 / 〇 "The following is preferable. Further, the fine particles of the present invention are preferably used to reduce the number of fine particles having an average particle diameter of 1 or less. When a large amount of the fine particles are contained, the transparency or brightness is reduced when the microparticles are used for optical purposes (for example, a light-diffusing film provided on the image display surface of various image display devices, an anti-glare film for reflection prevention, etc.). Therefore, the average particle diameter of ι/2 2226-9085-PF; Ahddub 8 200819470 or less granules of granules is preferably 1% by volume or less, more preferably the following. 〖to f 贝 /〇再者' The average particle size of the microparticles of the present invention is only a good one, preferably "." better, further; When the average particle diameter is within the above range, for example, optical:: day-to-day, it is advantageous in that it can exhibit good light diffusibility or surface luminescence (brightness). When the average particle size is too small, the yak low is a resin for the media, and when it is too large, there is a possibility that sufficient light diffusion effect cannot be obtained. 2: 'Particle size distribution measurement, average particle size, and 3 I of the above-mentioned fine particles, which is a precision particle size distribution device using the Coulter principle (for example, 'Beckman Coulter Beckman Coulter Co., Ltd.' Such as n

The measurement was calculated at a volume basis rate. J The shape of the fine particles of the present invention is not particularly limited, and is, for example, a spherical shape, a scaly shape, a scaly shape, a pulverized shape, a slanted shape, a stupid shape, and a gold syrup type ^ particularly when used for optical purposes (for The optical resin composition or the like, a spherical shape or a shape close to a substantially true sphere, and the ratio of the long particle size to the short particle diameter is 1 Q to 〗 〖, and the variation coefficient of the particle diameter is 1%. The above-mentioned fine particles of the present invention are obtained by dry-grading powder fine particles having a predetermined moisture content, true specific gravity, bulk specific gravity, and particle diameter. The powder particles for the above-mentioned dry classification have moisture content. In the case of 〇〇5~2, when the water content is too large, the water to be closed at the time of classification is agglomerated as a binder. In addition, when the water content is too small, the particles are condensed by static electricity in any case. All of them make the classification accuracy lower 9 2226-9085-PF; Ahddub 200819470 and there is an increase in the coarse particles of the two A », the employee's direction. As long as the moisture content is in the above range, the particles are not easy to coagulate, #7, Grading operation smoothly In addition, the true specific gravity is 1~1. 25g/ml, and the ping-pong 4 4 has a specific gravity of 〇·1~lg/ml, and the average particle size is 1~5 0 /zm. Powder and private za When the true specific gravity of the particles is too small, it is difficult to generate a centrifugal force of the size of the mouth particles or a 1* moon shape which is lowered in accuracy due to the difference in the impedance of the wind. When the true specific gravity is too large, _ requires a large amount of equipment and power. However, when the proportion of the product is too large, it requires a lot of equipment and power, and on the other hand, it is difficult to produce a situation in which the classification accuracy is lowered due to the difficulty in particle size. In the hour, the powders are strongly agglomerated together. 'There is no good dispersion state and the classification accuracy is lowered. When it is too large, it is not good because of the large equipment and power required.

By the wet classification, the content of the coarse particles having an average particle diameter of 2 times or more of the powder particles for dry classification and the dispersion solution obtained by wet classification is preferably 200,000 or less in 0.5 g. . Take 1 million: Better, step-by-step is better than 50,000. 5gw. As long as the dry-classified powder particles' and the coarse-sized particles of a specific size of the dispersion solution obtained by wet classification are within the above range, it is easy to obtain high yield and/or high by performing dry classification. The classification processing speed is preferably obtained by using fine particles having a small content of coarse particles. Therefore, the moisture content, the true specific gravity, the specific gravity and the particle diameter are preferably in the above range, and more preferably, the moisture content of the powder particles is preferably 〇. 〇5 !! % is good, and the true specific gravity is 1 to 1·5 g. /ral is preferred, the volume specific gravity is preferably 0.3 to 0.8 §/1111, and the average particle diameter is preferably 2 to 20//111. In addition, the above-mentioned "water content" is a value measured by a Karl Fischer moisture meter (Example 2226-9085-PF; Ahddub 10 200819470, a moisture measuring device manufactured by Hiratsuka Kogyo Co., Ltd.). The above-mentioned "monthly integration" refers to the amount of powder entering the container when the powder is placed in a certain volume in a certain state, and the mass per unit volume is not the case. The value 'is measured by a powder tester (manufactured by h〇s〇kaw MICRON). The "true specific gravity" of the powder particles is obtained by filling the powder particles into a container of a certain volume, and further replacing the gap of the sample with a liquid, by subtracting the volume of the liquid required at this time from the volume of the container f 2 The value of the relationship with the quality of the powder particles filled in the container is measured by the true specific gravity, and the value of the particle diameter is measured by the true weight of the 疋祛 丨 j疋祛G column, manufactured by SEISHIN Co., Ltd. The value based on the volume is measured by the above-described precise particle size distribution measuring apparatus (for example, "Multisizer-n" manufactured by Beckman Coulter Co., Ltd.). In the dry classification of the above powder fine particles, it is preferred to use a gas flow classifying device using wind power. The airflow classifying device 々1 is a device that separates fine particles (particle size (particle size, mass) of powder particles) by turbulent flow (that is, the inertia of the particles, that is, the resistance by the airflow) The balance determines the flight distance and is classified.) Usually, the material of the particles recovered by using only the sieve or the transition device of the transition device, / » r will depend on the mesh of the sieve used or the efficiency of the sieve. In order to obtain desired physical properties, for example, it is desired to obtain only a plurality of particles having a particle diameter in a specific range, and a plurality of classification operations are required. For this, a gas flow classifying device can be used to simultaneously remove coarse particles and fine particles. The classification mechanism is not particularly limited. Therefore, only the airflower's rotary rotor that imparts thrust to the airflow, or the air guide 2226-9085-PF; the deflector of Ahddub 200819470' uses the airflow generated by the composite action Furthermore, it is also possible to combine these and other classification means (screen or screen). As a specific air classification device, it can be mentioned: DXF type (曰本Pneumatic industry: system) Such as the south precision airflow classifying device; the turbo classifier (manufactured by Nissin Engineering Co., Ltd.), TURB〇pLEX (registered trademark, manufactured by H0S0KAW MICRON Co., Ltd.), etc. Use of the airflow classification device (Elbow-jet type classifier) using the Coanda effect, such as the Jet (the Nippon Mining Co., Ltd.), the dry type HIB0LTA (made by Toyo HITEC Co., Ltd.), the dry type bl〇wershifter (made by Y0UGR0P company), etc. The mesh classification device of the mesh. Among these, the high-precision airflow classifying device, the rotary rotor type airflow classifying device, and the airflow classifying device using the Coanda effect can effectively remove coarse particles. In the above-described surface-accurate airflow classifying device, there is no moving part (movable member) that generates a high-speed swirling airflow by dispersing the band and the gas flowing into the stepped zone, imparting centrifugal force to the particles in the supply device, and pairing them By imparting resistance to the force of the particles, the air is exhausted from the grading zone by the suction fan, and the device is classified into coarse powder and (4) by the balance of the force and the resistance. The rotary rotor type airflow classifying device , with freely rotatable: cylindrical rotor), and a suction port for taking in air from the outside of the device. The particles that are produced by the high-speed rotation of the rotor in the device are vortexed to impart centrifugal force. - Aspect, by the suction port, " becomes the resistance of the air of the force, by the balance of the centrifugal force and the resistance, the particles are classified into a device of coarse powder and fine powder. Using the Coanda effect gas 12 2226-9085-PF; Ahddub 200819470 flow grading device, the use of the wall surface only on the other side, the jet will flow along the wall surface of the Kangda effector, the earthquake Provided at any position: an injection portion that ejects particles together with a gas stream (supply gas) into the device, and a Kangda block that directs the jet to the classification chamber (including particles), and the particles are in accordance with the properties (coarse powder) , fine powder (object), micronized, etc.) isolated graded edges. The jet (including particles) ejected by the above-described emitting portion flows along the Coanda block. At this time, the inertial force acting on the particles (which acts on the inertial force of the small particles and the coarse particles is too far away), and the particles are classified into coarse particles and fine particles by the balance of the fluid impedance. Among the above airflow classifying devices, a gas flow classifying device (Elb〇W-Jet type classifier) using the Coanda effect is preferred. When using this Eib〇w_jet type classifier, it is better to increase the supply gas to the maximum recommended gas pressure in order to improve the classification accuracy. Furthermore, the 'normal' supply of gas is used. · Bu operation, suggested by the viewpoint of improving the classification accuracy. Generally, if the supply gas is too high, the flying distance of the coarse particles becomes long, and the collision of the coarse particles of the wall colliding with the front surface is likely to be mixed with fine powder. However, the microparticles of the present invention are obtained by the dry classification step after the wet classification step, and the coarse particles are removed by the above-described wet classification step: Degree: there is no coarse particle Bounce back and mix in fine powder. Because &, the classification accuracy can be improved by increasing the supply gas. Further, the use of a slim edge as a graded edge is also preferable for improving the classification accuracy. As described above, the graded edge is a user who isolates the particles according to the trait, and has a - end (particle entry side) thin ' with a thickened shape toward the other end. Further, the bottom section (having a thicker one end in the wedge shape) is slightly rectangular 2226-9085-PF; and the Ahddub 13 200819470 has a specific width. Further, the width of the graded edge is generally set to be slightly equal to the width of the flow path through which the jet containing the particles flows. Here, the above-mentioned cut, 'edge, and 彖 are formed at a short distance between the wedge-shaped slantes than the standard edges which are generally used (in particular, the bottom section is about half of the standard edge). Slim edges, usually used to prevent the handling of highly charged particles, will accumulate at the leading edge of the edge, reducing the accuracy of the classification. By using the fine edges, the reason for improving the accuracy of the knife level, and the purpose of the above-mentioned slim edges (suppressing the reduction of the classification accuracy due to the accumulation of particles), it is considered to be difficult to transmit.

Further, it is a particle for wet classification, and a large phase female worker has a double particle diameter of 2 times the particle size of the large coarse particle. The content of coarse particles with a large particle size of 2 times, the slaves are all pulled from the Ding 3 in the 5 g of the 5 g. It is better to use 500,000/0.5, and the next is better. Steps of 204/〇.5g or less may be used to disperse the pre-manufactured fine particles 2226-9085-PF; Ahddub 200819470 in a dispersion medium (water, organic solvent, etc.), and the microparticles are organically polymerized as described later. When the material or the organic inorganic composite material is composed, the reaction liquid after the polymerization reaction may be used as it is. Further, the fine particle dispersion obtained by the wet process can also be used as it is. The apparatus for wet classification of the above-mentioned fine particle dispersion can be particularly limited, and a centrifugal device, a liquid swirling device of inertial force, or the like can be used. f As a specific wet type grading device, a clip-on filter (for example, manufactured by Memori Co., Ltd., manufactured by Japan PAU Co., Ltd.), which is classified by centrifugal force (for example, manufactured by Touch Industries, Inc., (5) coffee company... ). The above-mentioned clip-on filter can also be used in combination, for example, for the purpose of reducing the operating cost by the life-saving, and the combination of the final filter for satisfying the required over-accuracy, and for the most desirable state.

Fine particles (amine-based resin) composed of an organic polymer, and fine particles composed of an organic inorganic composite material (the above (C)), structure and production method thereof f "Production method of amine-based resin bridging particles> % First, description A method for producing an amine-based resin (amine-based resin bridging particles) of fine particles composed of the above-mentioned organic polymer. The method for producing the amine-based resin bridging particles includes the first production method and the second production method described below. In the first and second manufacturing methods, in the synthesis stage of the fine particles, since the particle diameter can be controlled, the formation of coarse particles can be suppressed in some cases. Therefore, by the manufacturing method The obtained amino-based resin bridging particles can be easily subjected to the above-described process for obtaining the fine particles k of the present invention, and the content of the particles having a particle diameter deviated from the appropriate range can be easily reduced. First, the second production method will be described. - First Manufacturing Method - The first production method of the amine-based resin bridging particles (hereinafter referred to as "the first production method"), comprising: a resinization step of obtaining an amine-based resin precursor by reacting an amine-based compound with furfural The emulsification step of emulsifying the amine-based resin precursor obtained by the above resination step in an aqueous medium to obtain an emulsion of the amine-based resin precursor; and adding the catalyst to the emulsion obtained by the emulsification step to emulsify the amine group The resin precursor is subjected to a hardening reaction to obtain a hardening step of 2226-9085-PF; Ahddub 19 200819470 to the amine resin bridging particles. The above resination step is to cause the amine group compound to react with formaldehyde to form an initial condensation reaction amine group. The step of the resin precursor, the solvent ',,, soil', θ ^ in the reaction with formaldehyde, is used as the "application" of the resination step. The method is preferably a method of adding a reaction of an amine-based compound to a state in which formaldehyde is used as an aqueous solution (formalin), and a trioxane or a para-plate is added to water to produce a squash in water. A method of reacting an amine-based compound with a lyophilized aqueous solution, wherein the method of the former does not require the preparation of an aqueous solution, and the raw material is easy to handle, so that the economical point is even more ambiguous. In the case of any of the methods, the resination step is preferably carried out under stirring with a conventional mixing device, etc., and the amine group-based compound used as the distillate in the resination step is not particularly limited, and for example, , benzo melamine (2, [diamino 6 phenyl hexamethylene), hexylene carbonate melamine, cyclohexene carbon tripolycyanamide and dense material. Among these, an amine group having a triazine ring is more preferred. In particular, benzo melamine diamine contains a benzene ring and a reactive group of 2, and contains: polycyanide: an amine as an amine-based compound, and the resulting amine-based resin bridging particles are resistant to flexibility (hardness). It is particularly good for pollution, heat resistance, I* resistance/combination, and excellent chemical resistance. These amine-based compounds may be used alone or in combination of two or more. Among the total amount of the amine-based compound to be used, the above-mentioned amine-based compound (benzo-indole cyano-cyanoamine, cyclohexane-carbon melamine, cyclohexene-carbon di-dicyanoimide and dense The proportion of the amine is preferably 40% by mass or more, more preferably 60% by mass or more, further preferably 8% by mass or more, and 2226 to 9085-PF; Ahddub 20 200819470 0. ι 〇 0% by mass optimal. When the content of the above-mentioned amine-based compound is 40 or more, the resulting amino-based resin bridging particles are excellent in (iv) heat resistance and solvent resistance. The molar ratio of the amine-based compound to formaldehyde in the resinification step (amine-based compound (mole) / formaldehyde (mole)), preferably 1/3·5~1/; ι·5 It is preferably 1/3.5 to 1/1.8, and further preferably 1/3.2 to 1/2. When the above molar ratio is less than 1/3.5, the unreacted matter of formaldehyde is more and more, and the super-t is over 1 / 1 · 5 days, and the unreacted substance of the amine-based compound is more and more. Further, the concentration of the amine-based compound and the formaldehyde at the time of preparing the resination step is preferably a high concentration without hindering the reaction. Specifically, the viscosity of the reaction liquid containing the amine-based resin precursor of the reaction product in the temperature range of 9 5 to 9 8 is adjusted to 2 χ 1 (Γ2 to 5. 5xl 〇 2Pa · s (2 0~ The concentration in the range of 55cP) is preferably. In the emulsification step described later, the concentration of the amine-based resin precursor in the emulsion is in the range of 3 〇 6 to 6 畺 %, and the reaction liquid is used. The concentration of the aqueous solution added to the emulsifier or the aqueous solution of the emulsifier or the emulsifier may be added to the reaction solution. Therefore, the viscosity of the reaction liquid containing the amino resin precursor obtained by the resinification step in the temperature range of 95 to 98 C is obtained. , 2χ1〇-2~5. 5χ1 〇_2pa · s(20 ～55cP) is better, with 2.5χ1 (Γ2~5.5xl〇-2pa·s (25~55cp) more 仫, further to 3·0χ102 〜 5·5xl〇-2pa · s (3〇~55cp) is preferred. As a method for measuring the viscosity described above, it is possible to immediately grasp the progress of the reaction, and it is possible to correctly see the viscosity measuring machine using the end point of the reaction. The method is preferable. As such a viscosity measuring machine, a vibrating viscometer (manufactured by MIVIITS Japan Co., Ltd.) can be used. Product Name: MIVI6〇〇1). The viscometer, 2226-9085-PF; Ahddub 21 200819470 The vibration with constant vibration is immersed in the reaction liquid by the vibrating part, and the ▲ When a load is applied to the vibrating portion, the load is immediately converted into a viscosity index.

The amine-based resin precursor of the initial condensate can be transferred by reacting the amine-based compound with water in water (in an aqueous medium). The reaction temperature is as follows in the progress of the reaction, and the end point of the reaction can be accurately seen, preferably in the temperature range of 95 to 98 〇C. Then, the reaction of the amine-based compound human quinone 2 aldehyde is carried out by the operation of the reaction = cooling, etc., when the viscosity of the reaction liquid is within the range of 2xl 〇 2 to 5 · 5x10, can. Thereby, a reaction liquid containing an amine-based resin oxime body can be obtained. Further, the reaction time is not particularly limited. The amine-based resin precursor obtained in the step of deuteration, to form the molar ratio of the structural unit derived from the amine-based compound and the k-unit derived from formaldehyde to the precursor of the amine-based resin (from the amine-based compound) Construction unit (mole) / structural unit (mole) from A disk, preferably 1/3.5~1/L5, preferably 1/3.5~1/1.8, further 1/3·2~1/ 2 is better. When the molar ratio is within the above range, particles having a narrow particle size distribution can be obtained. Amine-based resin precursor, usually, for acetone or dioxane, decyl alcohol, ethanol, isopropanol, butanol, ethyl acetate, butyl acetate, thiol cellosolve, ethyl cellosolve, methyl ethyl ketone, hydrazine It is soluble in organic solvents such as benzene and paraben, and is substantially insoluble in water. In the first production method, the viscosity of the reaction liquid of the resinization step of preparing the reaction liquid containing the precursor of the above-mentioned amine resin is low, so that the particle diameter of the finally obtained amino resin bridged particles can be made small. However, when the viscosity of the reaction liquid is 22 2226-9085-PF; when Ahddub 200819470 is less than 2x10 2pa · s, or when it exceeds 5·5xi〇_2pa · s, it is difficult to obtain a final uniform particle size (small particle size distribution). The case of the amine-based resin bridging particles. That is, the viscosity of the reaction liquid is less than 2x1 (T2Pa · s (20cP)', and the emulsion obtained by the emulsification step described later lacks stability. Therefore, the amino resin precursor hardening-based resin bridging particles are enlarged in the curing step. Or the particles that agglomerate each other:: The particle size of the amine-based resin bridging particles has the advantage of being an amine-based resin bridging particle having a wide particle size distribution. Moreover, when the emulsion lacks stability, each (each Manufactured in batches, the particle size (average particle size) of the amine-based resin bridging particles changes, and there is a dispersion in the product. On the other hand, the viscosity of the reaction liquid exceeds 5×10 Pa s (55 cP), which is used for the latter. The load applied by the high-speed pulverizer or the like in the emulsification step is too large, so that the shearing force is lowered, so that the reaction liquid (which is opaque) cannot be sufficiently mixed. Therefore, it is difficult to control the finally obtained amine-based resin bridging particles. The particle size may be a case of an amine-based resin bridging particle having a wide particle size distribution. Therefore, it is preferable to adjust the reaction liquid to the above-mentioned viscosity range in advance in the "waxing step". >Emulsification step II' will be Resin The step of preparing the amine-based resin precursor precursor to prepare the emulsion of the amine-based resin precursor by the step of preparing the emulsion of the protective colloid by using, for example, 'using, for example, ' can constitute an emulsion of the protective colloid.

Use of an emulsifier The mass portion of the amine-based resin precursor (10) obtained in the above resination step is preferably a mass portion of the material, and a mass portion of the material is preferably 5. If the amount of use deviates from the above range, there is a lack of stability of the emulsion. Further, the more the amount of the emulsifier used for the amine-based resin precursor, the smaller the particle size of the generated particles tends to be smaller. In the emulsification step, for example, in the aqueous solution of the emulsifier, the amine-based resin is The concentration of the body (that is, the solid parting itching, the core knife/length) is added in the range of 30 to 60% by mass, and the reaction liquid obtained by the above resination step is added to a temperature range of 5 〇 to 1 〇〇. It is preferable to make it turbid in the range of 60 to 10 (r is more preferable, and further preferably 7 to 95 ° C. The concentration of the aqueous solution of the emulsifier is not particularly limited as long as the concentration of the amine resin precursor is made. It is sufficient to adjust the concentration within the above range. In the case where the concentration of the amine-based resin is less than 3 G mass%, the productivity of the amine-based resin bridging particles is lowered to 'more than 6 G mass%, and the resulting amine-based resin bridging particles are enlarged' or the particles are agglomerated together. The particle size distribution of the amine-based resin bridging particles which are trapped in the amine-based resin bridging agent & In the emulsification step, as a means for imparting a mixture, a device which can more strongly impart an aqueous solution of the above-mentioned amine-based resin precursor and an emulsifier (having a high shear force of 2226-9085-PF; Ahddub 24 200819470) is preferably used. As a specific stirring device, a mixer, a homogenizer, a TK homogenizer (Special Machine Chemicals Co., Ltd.) H = a disperser, a very original grinder (manufactured by Shirahara Seisakusho Co., Ltd.), a high = mixer (for example) (manufactured by MZUMJ FOOD MACHINARY), static-beat (manufactured by N0Rm〇Co·Ud), etc. ~, in the emulsification step, the amino resin precursor obtained by the resination step promotes emulsification to a predetermined particle size Further, it is preferable that the predetermined particle diameter, f is the amino resin bridge bridging particle of the final desired particle size. Specifically, by considering the speed of the container or the stirring blade, the mixing time, and the emulsification The temperature, etc., the average particle size of the emulsified amine-based precursor is 〇."0" emulsification is better, to .5~2. "Better, further with Bu 5 " is better. By setting the amine-based resin precursor to the above-described particle diameter range, the amine-based resin bridging particles can be in a desired range. The first production method is in order to reliably prevent the final amine-based resin from bridging the particles. Cohesion, as needed, In the emulsification step, inorganic particles are added to the obtained emulsion.

As the acid catalyst, hydrochloric acid, sulfuric acid, magnetic chu zhi into the mineral acid of the yak 酉夂 4; the ammonium salt of the mineral acid; sulfinic acid, benzoate acid, 斟田免# A sulfonic acid such as a sulfonic acid or a lauryl benzene sulfonic acid; a phthalic acid; a vegetable acid such as a phthalic acid, a vegetable, a vinegar, a propionic acid, a salicylic acid, or the like. Among the above-mentioned acid catalysts, it is preferable to use mineral acid at the point of speeding up, and further, to the rot of the device, to use the safety of the mineral acid, such as the use of soda, to sulfuric acid. Better. In addition, when sulfuric acid is used as the above catalyst, for example, when the use of lauryl benzoic acid is used, the resulting amine-based resin bridging particles are less likely to change 2226-9085-PF; Ahddub 26 200819470 can be used in combination with color and solvent resistance. High and good. These acid catalysts may be used alone or in combination of two or more. The amount of the above-mentioned catalyst used is preferably from the mass fraction of the amine-based resin precursor in the turbid liquid obtained by the above-mentioned emulsification step, and is preferably 〇·1 to 5, and 暂. 3 to 4 · 5 mass parts are better, and further, the mass of the 质量·5~4. 0 mass part is more than 5 mass parts, which will destroy the opaque energy, and the particles will condense together. 〇·丨 Quality Department, it takes a long time to react, or hardening is not very difficult.

The end of the hardening reaction can be judged by sampling or visual observation. Moreover, the reaction time of the hardening reaction is not particularly limited. It is preferred to carry out the stirring and the lowering, as a stirring means, as long as the conventional stirring device is used. In the hardening step, the turbid amine 2226-9085-PF; Ahddub 27 200819470 base resin w is hardened. The average particle size of the amine-based resin bridging particles is 〇·1 20/zm is preferred, preferably 〇·5~20//m, further preferably 卜5#m. 、,, in the first manufacturing method, may also be included in the emulsion or amine of the amine resin precursor. The coloring step of the aqueous solution of the resin bridged particles is added to the coloring step of dissolving the dye in water. In the first manufacturing method, the suspension containing the amine resin bridging particles obtained by the hardening step may be carried out. And a neutralization step. The neutralization step is carried out in the above-mentioned hardening step, using an acid catalyst such as sulfuric acid as a hardening catalyst. By performing a neutralization step, the above acid catalyst can be removed (specifically, an amine resin bridge is bridged). The discoloration of the amine-based resin bridging particles when the particles are hot (for example, discoloration into yellow). ^ The 悬 of the suspension of the granules of the granules is more than 5, making it (4) better. When the suspension is less than 5, the acid catalyst remains in the heating step described later, etc., in which the amine resin bridging particles are discolored.

Can only be on. 1 Emperor uses δ 荨 荨 1 type can also be used in combination with 2 kinds of 2226-9085-PF; Ahddub 28 200819470 In the first manufacturing method, it can also be set after the hardening step or after the neutralization step, the female-based resin bridging particles The suspension, & the separation step of the amine-based resin bridging particles. As a method of separating the amine-based resin bridging particles from the suspension (separation method), a method of filtering or a separator using a centrifugal separator or the like can be used as a simple method, and i is not particularly limited [a conventionally known separation method) Can be used. Further, the amine-based resin bridging particles taken out from the suspension may be washed with water or the like as needed. In the first production method, it is preferred to carry out a heating step of heating the temperature of the amino resin bridged particles 'α 130 to 1 90 C taken out through the separation step. By performing a heating step, the moisture attached to the amine-based resin bridging particles and the remaining free (unreacted) furfural can be removed, and the condensation (bridging) in the particles of the amine tree eucalyptus bridge can be further promoted. The above heating temperature is higher than that of work 3. . . When it is low, the condensation (bridge) in the bridging agent of the amine resin cannot be sufficiently promoted, and the hardness, solvent resistance, and heat resistance of the amine-based resin bridging particles cannot be improved. When the ratio exceeds 19 (TC, the obtained amino-based resin) The bridging particles have discoloration. Even in the case of the above neutralization step, the influence of the heating temperature outside the above temperature range is the same. The characteristics of the obtained amine-based resin bridging particles (hardness, solvent resistance, heat resistance) can be improved. From the viewpoint of the property and the discoloration resistance, it is preferred that the heating temperature of the amine-based Schausal bridging particles is within the above range in the preparation and the step n. The heating method in the heating step is not particularly limited as long as it is usually used. The heating method may be any.

The amine-based resin bridging particles obtained by the manufacturing method of Yudi 1 are drawn from the water system in the above emulsification. After drying and pulverization, the obtained (I) may be dispersed in the suspension for the wet and dry classification steps. Further, the suspension after the hardening step (including the hardening step, after the neutralization step) The liquid or the like "any suspension for the separation step" for wet classification is also a preferred aspect of the method of the present invention. The wet-graded suspension is subjected to the above-mentioned knife-off step After the heating step, it is dried and pulverized to obtain powder fine particles having a water content of 5% to 2% by mass, which is preferably used for the dry classification step. The second method for producing the amine resin bridging particles will be described. - Second Production Method - "The second production method of the amide-based resin bridging particles (hereinafter, referred to simply as the second production method)" is an amine obtained by reacting an amine-based compound with formaldehyde. a base resin precursor mixed with a surfactant in an aqueous medium, #, after the mixture is added to the mixture to cause the amino resin precursor to be particle-formed in the aqueous medium, the amine resin bridging particles are A method in which the medium is separated and dried, and the obtained dried product is pulverized. In the second production method, similarly to the Jth production method, a resination step is employed in which the amine-based compound is reacted with formaldehyde to form an amine-based resin precursor. In the second manufacturing method, by using a mixing step of mixing the amine-based resin precursor obtained by the resination step with an surfactant in an aqueous medium, the precursor comprising the amine-based resin and the interface = 2226 to 9085 ~PF; Ahddub 30 200819470 The mixture of the catalysts is added to the catalyst to form particles and precipitate by hardening of the amine resin precursor. The point of obtaining the curing and particle-forming step of the amine resin bridging particles is different from that of the first production method. In the second production method, the amine-based resin bridging particles having a small particle diameter are easily prepared by starting the curing of the amino resin precursor in an aqueous solution state (for example, the average particle size is from 〇1 to 50//m). In addition, as the amine-based compound to be used in the second production method, the type and composition ratio of the water-mixing property described later in the following paragraphs are appropriately set, for example, and can be reacted with formalin to form a water-soluble amino resin precursor. The amine compound of the body is preferably as necessary. Further, the amine-based resin precursor obtained by the resination step is a surfactant which is used in the second production method in water solubility, and is used in water (IV) for the amino resin precursor, and is suitable for water affinity. The surfactant ' does not contain the emulsifier used in the i-th manufacturing process.

The amine-based resin precursor drops the amount of swarf water until the amount of white turbid water is dropped; ^ the mass of the condensate (hereinafter, referred to as water mixing degree), the heart is large, and the water is not affinitive The higher. Further, in the second production method, the water mixture degree from the base resin precursor is preferably im or more. In the water-mixed core 100% amino-based resin precursor, even if the basket is dispersed in the aqueous liquid containing the interface agent, the r? band can be used, and the 曰, which forms a relatively large particle size. The spheroidal microparticles that are finally obtained are difficult to be uniform particle size (grain stone cloth is wider). In the mixing step, the amine-based resin precursor obtained by the resinification step is used, and the mixed solution is prepared by mixing with a surfactant in a water-based medium. As the above surfactant, for example, an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, or the like, in particular, an anionic surfactant or a nonionic surfactant can be used. Sexual surfactants or mixtures of these are preferred.

The amount of the surfactant to be used is preferably in the range of 100 parts by mass of the amine-based resin oxime body obtained by the above-mentioned resinification step. In the case of less than 0.01 parts by mass, there is a case where a suspension of the stability of the amine-based resin bridging particles is not obtained, and if it exceeds 10 parts by mass, unnecessary foaming occurs in the suspension or there is an amine obtained finally. The situation in which the physical properties of the resin bridging particles cause adverse effects. 2226~9085-PF; Ahddub 32 200819470 In the mixing step 'for example, in the aqueous solution of the surfactant, the concentration of the resin precursor (ie, the solid concentration, the mouth-shaped concentration) is in the range of 3 to 25% by mass. In the interior, it is preferred to add the reaction solution after the addition of the above resinization step. In this case, the aqueous solution of the surfactant is not particularly limited, and it is only necessary to adjust the concentration of the amine-based resin precursor to the concentration within the above range. In the above-mentioned amine-based resin precursor, if the Cong/Chen degree is less than 3% by mass, the reduction of the supply of the amine-based resin bridging particles is reduced, and if it exceeds 25% by mass, the obtained amine-based resin bridging particles are obtained. In the case of hypertrophy or aggregation of particles, since the particle size of the amine-based resin bridging particles cannot be controlled, there is a problem that the amine-based resin bridging particles having a wide particle size distribution are available. As a stirring method in the mixing step, the mouth/and the general stirring method may be used, for example, a disk turbine, a blade, a quotation, a wheel, a method, a spiral, a multi-segment, and the like.

The quality part is better, and further the quality part is better.” The amount of use is not less than the above range, and it takes a long time for the condensation hardening, and the suspension of the stability of the amine-based resin bridging particles cannot be obtained, and finally, only a large amount of agglomerated coarse state can be obtained. Further, in the case where the amount exceeds the above-mentioned range, the catalyst of the above-mentioned phenolic acid or the like is distributed in the amine resin bridging particles in the resulting suspension, and the amine resin bridging particles are plasticized. On the other hand, it is easy to cause aggregation or fusion between particles in condensation hardening, and finally, it is impossible to obtain an amine-based resin bridging particle having a uniform particle diameter.

The average particle diameter of the preferred amine-based resin bridging particles is the same as that of the amine-based resin bridging particles in the hardening step of the first production method. The second manufacturing method may include: performing a step of neutralizing a suspension containing the amine-based resin bridging particles obtained by the above-mentioned hardening step. The details of the pH range of the neutralization step or the type of the neutralizing agent can be the same as in the first production method. / 2nd manufacturing method, the suspension of the amine-based resin bridging particles obtained after the hardening, the particle-forming step or after the neutralization step may be a separation step of taking out the amine-based resin bridging particles. Further, in the second production method, the amine resin bridging particles are separated and removed from the suspension, and the amino group-branched particles obtained by the hardening are separated and taken out from the aqueous medium in the mixing step. The method (separation method) of taking out the amine-based resin bridging particles from the suspension can be carried out in the same manner as the second method.
