DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the manufacture of inorganic flame retardants. More particularly, the present invention relates to a method for producing an aluminum hydroxide flame retardant having improved thermal stability. [Prior Art] Aluminum hydroxide has a number of different names, such as hydrated aluminum, trihydrate, etc., but is commonly referred to as ATH. ATH particles have many uses, such as those in φ materials (such as paper, resin, rubber, plastics, etc.). The product can be used in a variety of commercial applications such as cable and wire sheathing, thermoplastic molds, adhesives, and the like. ATH is generally used to improve the properties of this material and also as a smoke suppressant. ATH is also commonly used as a flame retardant in the manufacture of printed circuit board grease. Therefore, the thermal stability of ATH is the quality of the end user's attention. For example, in printed circuit board applications, the thermal stability used to build the slab must be high enough to lead-free soldering. The synthesis and manufacturing methods of ATH are known in the art. However, the demand for the φ ATH rating is increasing, and current methods cannot make all of this. As the demand for custom ATH grades increases, so does the need to manufacture these methods. SUMMARY OF THE INVENTION While experimental evidence indicates that the thermal stability of ATH is related to the total content of ATH, the inventors herein have discovered and believed that although it is not intended to be limiting, the improved thermal stability of invented ATH and the insoluble sodium-base are included. It is generally about 70% of the total sodium alkali content based on the total sodium alkali weight.) Many of these belts of Mingguan, many of the flame retardant trees are stapled to order some of the equivalent grades of sodium bases with 99 200811045 weight % range, the rest is soluble sodium base. The inventors also believe that although it is not desired to be bound by theory, the wetting force of the ATH particles to the resin depends on the morphology of the ATH particles, and the inventors have unexpectedly discovered that improved wetness can be produced with respect to existing ATH using the method of the present invention. ATH ATH particles. While not wishing to be bound by theory, the inventors believe that this improved wetting force is due to an improvement in the morphology of the A Τ particles produced by the methods disclosed herein. The inventors further believe that although not wishing to be bound by theory, this modified form is attributed to the total pore volume ratio of the ruthenium particles and/or the median pore radius ("r5"). The inventors believe that for a particular polymer molecule, the ATH product with a higher structured aggregate contains more and larger pores and appears to be more difficult to wet, resulting in a kneader or twin screw such as a Buss Ko-kneader. Diffuser (higher variation in motor power) during extrusion or other machines known in the art and used for this purpose. The inventors have therefore discovered that a material characterized by a small median pore size and/or a small total pore volume is associated with improved wetting force on the polymeric material, thus resulting in improved composite behavior, i.e., for compounding The engine (motor) of the composite machine containing the flame retardant resin has a small power variation. The inventors have found that the method of the present invention is particularly suitable for use in the manufacture of features. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a method for producing ruthenium product particles by honing dry filtered wet cake to produce honed dry mash particles (containing a binder) and then deagglomerating the honed dry ruthenium particles. In this particular embodiment, the wet cake is filtered to contain cerium particles in the range of from about 25 to about 85% by weight, and the cerium product particles have a median radius of the hole 200811045 in the range of from about 0. 09 to about 0. 3 3 microns (" R5〇"). In another embodiment, the ATH product particles produced in accordance with the present invention have a Vmax in the range of from about 300 to about 700 cubic millimeters per gram, i.e., a maximum pore volume ratio of <RTIgt; R50 in the range of about 0.33 micrometers, i.e., the pore radius at a relative pore volume ratio of 50%, and one or more, preferably two or more, and more preferably three more, in some embodiments. All of the following characteristics: i) d5() from about 5 to about 2.5 microns; ii) less than about 〇·4% by weight of the total sodium alkali φ content based on the total weight of the honed dry ATH particles ; iii) an oil absorption of less than about 50% as determined by ISO 787-5:1 980; and iv) a surface area ratio (BET) of from about 1 to about 15 square meters per gram as determined by DIN-6 6132, wherein honing The conductivity of the dried ATH particles was less than about 200 μS/cm measured in 10 wt% ATH in water. The ruthenium product particles produced by the present invention can be used as flame retardants in various flame retardant resin formulations, sometimes referred to as flame retardant tanning or simply as tanning materials. In some embodiments, the bismuth product particles of the present invention are further characterized by having a soluble sodium alkali content of less than about 0.1% by weight. • [Embodiment] It should be noted that all particle size measurements disclosed herein, i.e., d5G, were measured by laser diffraction using a Cilas 1 064 L laser spectrometer from Quantachrome. The procedure generally used herein for measuring d5G can be carried out by first introducing a suitable water-dispersant solution (prepared as described below) into the sample preparation vessel of the apparatus. Then select the standard measurement called “Particle Expert” and also select the measurement model “Range 1” and then select the internal parameters of the device that are appropriate for the expected particle size distribution. It should be noted that during the measurement, the sample is typically exposed to the ultrasonic wave for about 60 seconds during the measurement and during the measurement period of 200811045. After the background measurement is completed, about 75 to about 100 mg of the sample to be measured is placed in a sample container with a water/dispersant solution and measurement is started. The water/dispersant solution can be prepared by first preparing a concentrate from 500 grams of Calgon from KMF Laborchemie and 3 liters of CAL Polysalt from BASF. This solution was made up of 10 liters of deionized water. The original 10 liters of 10 ml was taken and further diluted to 10 liters with deionized water, and the final solution was used as the above water-dispersant solution. 10 Filter Cake The present invention comprises a filtered wet cake comprising ATH particles, sometimes simply referred to as a filter cake, honed and dried to produce honed and dried ATH particles. The filter cake typically comprises from about 25 to about 85% by weight of ATH particles, based on the total weight of the filter cake. In a preferred embodiment, the filter cake contains from about 40 to about 70 weight percent ATH particles, more preferably ATH particles in the range of from about 55 to about 65 weight percent, which are all based on the same calculations. In other embodiments, the filter cake contains from about 40 to about 60 weight percent of the ATH particles, more preferably from about 45 to about 55 weight percent of the ATH particles' which are all based on the same calculations. In still other embodiments, the filter cake comprises from about 25 to about 50 weight percent ATH particles, more preferably from about 30 to about 45 weight percent ATH particles, which are all based on the same calculations. The filter cake used in the practice of the present invention can be obtained by any of the methods used to make ATH particles. Preferably, the filter cake is obtained by a process involving the manufacture of ATH particles by precipitation and filtration. In an exemplary embodiment, the filter cake is prepared by dissolving the crude aluminum hydroxide in caustic to form a sodium aluminate solution, cooling it and filtering it in 200811045, thus forming a specific embodiment for use in the exemplary embodiment. The method of sodium aluminate solution is obtained. The sodium aluminate solution thus produced generally has a Na2〇 to Al2〇3 molar ratio in the range of from about .4:i to about 1.55:1. For the sodium sulphate® ATH granules, the ATH grain is added to the sodium aluminate solution in an amount of about 3 grams of ATH grain per liter of sodium aluminate solution to about 3 grams of ATH grain per liter of sodium aluminate solution.

After the addition of the ATH grain, the process mixture is stirred for about 1 Torr, or until the ratio of N a2 Ο Φ to Al 2 〇 3 mole is in the range of about 2.2:1 to about 3.5:1, thus forming an ATH suspension. The resulting ATH suspension typically comprises from about 8 Torr to about 160 grams per liter of ATH, based on the suspension. However, the ATH concentration can be varied to fall within the above range. The resulting ATH suspension is then filtered and washed to remove impurities therefrom, thus forming a filter cake. Before the filter cake is honed and dried, it may be washed once with water (preferably with demineralized water) or, in some embodiments, more than once with ATH particles in the mash cake. In some embodiments, The BET of the ATH particles in the cake ranges from about 1.0 to about 4·0 square meters per gram. In these embodiments, it is preferred that the AT ruthenium particles in the filter cake have a BET in the range of from about 1.5 to about 2.5 square meters per gram. In these embodiments, the ruthenium particles in the filter cake may also and preferably are characterized by a range of from about 1.8 to about 3.5 microns, preferably from about 1.8 to about 2.5 microns, which is the ATH product produced herein. The particles are coarse. In other embodiments, the BET of the ATH particles in the filter cake ranges from about 4 Torr to about 8.0 square meters per gram, preferably from about 5 to about 7 square meters per 200811045 grams. In these embodiments, the ATH particles in the filter cake may also and preferably are characterized by a range of from about 1.5 to about 2.5 microns, preferably from about 1.6 to about 2.0 microns, which is more than that produced herein. The ruthenium product particles are coarse. In still other embodiments, the BET of the ATH particles in the filter cake ranges from about 8.0 to about 14 square meters per gram, preferably from about 9 to about 12 square meters per gram. In these embodiments, the ATH particles in the filter cake may also and preferably are characterized by a range of from about 1.5 to about 2.0 microns, preferably from about 1.5 to about 1.8 microns, which is more The manufactured product particles were coarse. The Φ is larger than the ATH product particles, and the upper limit of the d5G ATH of the ATH particles in the filter cake is usually about 0.2 μm higher than the upper limit of the d5G ATH of the ATH product particles produced herein. The ATH particles used in the filter cake of the present invention may also and preferably be characterized as having a total sodium content of less than about 0.2% by weight based on the AT Η particles in the filter cake. In a preferred embodiment, if the soluble sodium alkali content is characteristic of the cerium particles, the total sodium alkali content is less than 〇·18% by weight, more preferably less than 〇·1 2 , based on the total weight of the cerium particles in the filter cake. weight%. The total sodium content of strontium is 0. It can be measured using an M7DC flame photometer from Dr. Bruno Lange GmbH, Dtisseldorf/Germany. In the present invention, the total sodium content of the ath particles is obtained by first adding 1 gram of ATH particles to a quartz glass bowl, then adding 3 ml of concentrated sulfuric acid to the quartz glass bowl, and carefully stirring the glass bowl with a glass rod. Measured by contents. The mixture was then observed, and if the ATH crystals were not completely dissolved, another 3 ml of concentrated sulfuric acid was added and the contents were again mixed. The bowl is then heated on a hot plate until excess sulfuric acid has completely evaporated. The contents of the quartz glass bowl are then cooled to about room temperature and about 50 milliliters of deionized water is added to dissolve the any salt in the bowl. The contents of the bowl are then allowed to warm for about 20 minutes until the salt dissolves. The contents of the glass bowl were then cooled to about 20 ° C, transferred to a 500 ml volumetric flask, then filled with deionized water and shaken to homogenize. The total sodium alkali content of the ATH particles of the solution in the 500 ml vial was then analyzed by flame photometry. The ATH particles used in the filter cake of the present invention may also and preferably are characterized by a soluble sodium alkali content of less than about 0.1% by weight based on the ATH particles in the filter cake. In other embodiments, the ruthenium particles in the filter cake may further be characterized by having a soluble sodium alkali content ranging from greater than about 0.001 to about 0.1 weight percent, and in certain embodiments from about 0.02 to about 0.1 weight percent, They are all based on the ATH particles in the filter cake. In still other embodiments, the ATH particles can be further characterized as having a range of from about 0.001 to less than 0.04 weight percent, and in some embodiments from about 0.001 to less than 0.03 weight percent, in certain embodiments, in the range of from about 0.001 to less than 0.03 weight percent. Some specific examples are from about 0.001 to less than (K 02% by weight of soluble sodium base content, which are all based on the same calculation. The soluble sodium alkali content is measured by a flame photometer. To measure the soluble sodium content, A sample solution was prepared as follows: 20 grams of the sample was transferred to a 1 000 ml volumetric flask and leached in about 25 ml of deionized water for about 45 minutes in a water bath of about 95 ° C. The flask was then cooled to 20 °C, fill with deionized water to the calibration mark, and shake to homogenize. After the sample settles, a clear solution is formed at the neck of the bottle, and the flame photometer can be removed from the flask by the help of a syringe or using a centrifuge. The desired solution. The ATH particles used in the filter cake of the practice of the present invention can also be described as having a total sodium content of from about 70 to about 99.8% by weight of the insoluble -11-200811045 sodium alkaloids described herein. The remainder is soluble sodium. The inventors have unexpectedly discovered that the thermal stability of ATH is related to the total sodium content of ATH. Although experimental evidence indicates that thermal stability is related to the total sodium content of ATH, the inventors believe that although not It is intended that, by theory, the improved thermal stability of the ATH particles produced by the process of the present invention is related to the insoluble sodium base content, which is generally in the range of from about 70 to about 99.8% by weight of the total sodium base content, with the balance being soluble sodium base.

Honing Drying As discussed above, the present invention relates to honing and drying filter cakes. The honed and dried ATH granules are produced, wherein the ATH granules in the filter cake have the specified properties, as described above. The "honing and drying" and "dry honing" used herein means the turbulence of the filter cake in the honing and drying unit. Drying in a hot gas stream. Honing and drying single -12-200811045 includes a rotor that is firmly mounted on a solid shaft that rotates at a high peripheral speed. In combination with the rotational movement of the high air output, the hot air flowing through is converted into a very fast air whirl, which drives the mixture to be dried (ie the filter cake), accelerates, and distributes and drys the mixture, thus producing a honed dry A Τ Η Particles. The honed dry granules are transported out of the honing machine via the turbulent air after they have been completely dried, and are preferably separated from the hot air and steam using conventional filter systems. In another embodiment of the invention, the honed and dried ruthenium particles are transported through the turbulent air through a turbulent air that is integrated into the honing machine, and then transported through the turbulent air. Machine, and use a conventional filter system to separate from hot air and steam. The output of the hot air used to dry the cake is generally greater than about 3,000 Bm3/hour, preferably greater than about 5,000 Bm3/hour, more preferably greater than about 3,000 Bm3/hour to about 40,000 Bm3/hour, and most preferably about 5,000. Bm3 / hour to about 30,000 Bm3 / hour. To achieve this high output, the rotor of the honing and drying unit typically has a greater than about 40 meters per second, preferably greater than about 60 meters per second, more preferably greater than about 70 millimeters per second, and most preferably about 70 meters per second. The peripheral speed in the range of seconds to about 140 m/s. The high rotational speed of the rotor and the high hot air output result in a hot air flow with a Reynolds number greater than about 3,000. The temperature of the hot gas stream used to honed the dried filter cake is typically greater than about 150 ° C, preferably greater than about 27 (TC. In a more preferred embodiment, the temperature of the hot gas stream is from about 150 ° C to about 55 (the range of TC, preferably in the range of from about 270 ° C to about 500 ° C. In a preferred embodiment, the honed dry filter cake is honed to have a large BET surface area ratio of -13 to 200811045 The dried ATH particles, as determined by DIN-66132, then become the starting ATH particles in the filter cake. Generally, the BET of the honed dry ATH is greater than about 10% of the ATH particles in the filter cake. The BET of the dried ATH is greater than about 10% to about 40% of the ATH particles in the filter cake. More preferably, the BET of the ATH by dry honing is greater than about 10% to about 25% of the ATH particles in the filter cake. The honed dry ATH granules produced can be used "directly" for many applications. However, in some embodiments, the ATH dry ATH granules are further processed to reduce, or in some embodiments, Poly. The formation of cohesive polymers is common in ATH granules, and its presence is acceptable in some applications. The damage affects the properties of the ATH particles in the resin. Therefore, ATH is highly desirable to reduce, preferably to eliminate, the binder. In the practice of the present invention, the amount or cohesive of the cohes present in the honed and dried ATH particles The degree is reduced by subjecting the honed and dried ATH particles to a de-agglomeration process. De-agglomeration · De-agglomeration means that the honed dry ATH particles are subjected to further processing, wherein reduction, in some embodiments Substantially eliminating the amount or degree of cohesiveness present in the honed dry ATH particles (ie, the amount of cohes present in the honed dry ATH particles is greater than the amount of cohes present in the ATH product particles) The amount of honed dry mash has a very small particle size reduction. "Small amount of reduced particle size" means that the d5 ATH of the ATH product particles is greater than or equal to 90% of the honed dry ATH granules. In a preferred embodiment, The d5 crucible after honing and drying ATH is in the range of about -14 - 200811045 90% to about 95% of the honed and dried ATH granules, more preferably about 95% to about 99% of the honed and dried granules. In the practice of the present invention The amount or degree of cohesive mass in the honed dry ATH granules is reduced by the use of an air classifier or a pin honing machine. Air classifiers suitable for use herein include the use of gravity, centrifugal force, inertial force, or any combination thereof. While classifying ATH product particles, the use of these classifiers is known in the art, and those skilled in the art and familiar with the final product size can readily select a classifier containing a suitable mesh and/or screen. Pin honing machines include dry and wet pin honing machines. As with air classifiers, the use of pin honing machines is known in the art, and those skilled in the art and familiar with the final product size can easily select the best pin. A honing machine for specific applications. The de-agglomeration of the ATH by dry honing is carried out under conditions effective to produce ATH product particles having the following discussion. The ATH product particles in accordance with the present invention typically produce ATH product particles generally characterized by a specified total pore volume ratio and/or median pore radius ("r5"), in addition to one or more, preferably by the method of the present invention. Two or more, and more preferably three more, in some embodiments, all of the following features: i) d50 from about 5 to about 2.5 microns; ii) based on the total weight of the ATH product particles a total sodium alkali content of less than about 0.4% by weight; iii) an oil absorption of less than about 50% as determined by ISO 7 87-5: 1 890; and iv) from about 1 to about DIN-66 1 32 A surface area ratio (BET) of 15 square meters per gram, wherein the conductivity of the ATH product particles is less than about 200 pS/cm in water at 10% by weight of ATH. -15- 200811045 As noted above, the inventors believe that for a particular polymer molecule, ATH particles with a higher structured aggregate contain more and larger pores and appear to be more difficult to wet, resulting in, for example, Buss Κο- The kneading machine or twin-screw extruder of the kneader or the difficulty of compounding during the compounding of other machines known in the art and used for this purpose (higher variation in motor power). The inventors have found that the process of the invention is particularly suitable for the manufacture of ruthenium product particles characterized by a small median pore size and/or a small total pore volume, which is associated with improved wetting of the polymeric material, thus resulting in improved The composite behavior, that is, the engine (motor) used for composite composite materials containing the flame retardant resin has a small power variation. The r5G of the ruthenium product particles and the pore volume ratio ("Vmax") at about 1 〇〇〇 can be obtained from mercury porosimetry. The principle of mercury porosimetry is based on the physical principle that non-reactive, non-wetting liquid does not penetrate the pores until sufficient pressure is applied to force it into. Therefore, the higher the pressure required for the liquid to enter the hole, the smaller the porosity. It has been found that a smaller pore size and/or a lower total pore volume ratio is associated with a better wetting force of the ATH product particles. The porosity of the ATH product particles produced herein can be calculated using the Porosimeter 20 00 ^ from Italian Carlo Erba Strum entazione. According to the manual of P o r o s i m e t e r 2 0 0 0, the hole radius r is calculated from the measured pressure p using the following equation: r = -2Ycos(e)/p; where Θ is the wetting angle and γ is the surface tension. The measurement used here uses 141.3 ° and γ is set to 480 dynes/cm. In order to improve the reproducibility of the measurement, it is calculated by the second intrusion test to calculate the porosity of the dried ruthenium particles as described in the manual of Porosimeter 2000. The second test was used because the inventors observed that after the intrusion, that is, after releasing the pressure to the surrounding pressure, the amount of mercury remaining in the sample of the ATH-dried ATH particles was -16-200811045. Thus, r5G can be obtained from this data, as explained below. In a first test, a sample of the ATH product particles produced by the method of the present invention was prepared as described in the manual of Porosimeter 2000, and the pore volume was measured as a function of the applied intrusion pressure P using a maximum pressure of 1000 bar. At the end of the first test, the pressure is released and the ambient pressure is reached. A second intrusion test using the same pure ATH product particle sample from the first test (according to the manual of Porosimeter 2000) was carried out, wherein the pore volume ratio of the second test • V(p) measured the volume V〇 as the new starting volume, Then set it to zero for the second test. In the second intrusion test, the pore volume ratio v(p) of the sample was again measured as a function of the applied intrusion pressure p using a maximum pressure of 1 000 bar. Here, the pore volume at about 1 000 bar (ie for measuring the maximum pressure) is called Vmax °. The second ATH product particle intrusion test is performed, and the Porosmeter 2000 is used to calculate the hole according to the formula r = -2YC〇S(e)/p. Radius r; where Θ is the wetting angle, ® γ is the surface tension, and P is the intrusion pressure. For all r-measures used herein, 141 · 3° is used and γ is set to 480 dynes/cm. If necessary, the hole volume ratio can be plotted against the hole radius r to plot the resulting result. By definition, the pore radius at a relative pore volume ratio / 5 〇% is referred to herein as the pore volume median r 5 〇. For a graph of r5D and Vmax, see U.S. Provisional Patent Application Nos. 60/818,632; 60/818,633; 60/818,670; 60/815,515; and 60/8 1 8,426, all of which are hereby incorporated herein by reference.
