Description

200400920 (1) 玖、發明說明 【發明所屬之技術領域】 本發明係關於一種含有鋁的沉澱矽石,其具有可調整 的BET/CTAB比,其製法和其用途。 【先前技術】 已經知道沉澱矽石於彈料混合物(如:輪胎)之使用。 高需求針對用於輪胎的矽石。它們必須容易分散於橡膠 中,及視情況地於偶合劑存在時,必須具有與橡膠或其他 塡料中所含的聚合物鏈之良好連接。除了矽石的可分散性 以外,比表面積(BET或CTAB)和吸油性(DBP)亦重要。比 表面積是矽石的總表面積(B E T)或外在表面積(C T A B )指 標,這兩種方法皆利用尺寸有變化的分子作爲吸附劑。這 些表面積係數比(即BET/CTAB表面積商)提供矽石孔洞尺 寸分佈的指標及矽石的’’總"與”外在”表面積關係。矽石的 表面積性質實質上決定它們的可能應用,或者,矽石的特 定應用(如:用於彈料混合物的載體系統或塡料)須要某些 表面性質。 因此,US 6 013 234提出BET和CTAB表面積是100 至3 5 0 m2/g的沉澱矽石之製造。此矽石特別適用以摻入彈 料混合物中,此處,BET/CTAB比介於1和1.5之間。 EP 〇 9 3 7 7 5 5提出各式各樣沉澱矽石,其BET表面積約 180至約430m2/g,CTAB表面積約160至340m2/g。這些 矽石特別適合作爲載體材料且BET/CTAB比是1.1至 1.3。EP 0 647 591提出一種沉澱矽石,其BET/CTAB表 (2) (2)200400920200400920 (1) 发明. Description of the invention [Technical field to which the invention belongs] The present invention relates to a precipitated silica containing aluminum, which has an adjustable BET / CTAB ratio, a preparation method thereof, and a use thereof. [Previous Technology] The use of precipitated silica in ammunition mixtures (such as tires) has been known. High demand is for silica for tires. They must be readily dispersible in rubber, and optionally in the presence of a coupling agent, must have a good connection to the polymer chains contained in the rubber or other rubber. In addition to the dispersibility of silica, specific surface area (BET or CTAB) and oil absorption (DBP) are also important. The specific surface area is an indicator of the total surface area (B E T) or external surface area (C T A B) of silica. Both methods use molecules with varying sizes as adsorbents. These surface area coefficient ratios (ie BET / CTAB surface area quotients) provide an indicator of the distribution of the pore size of the silica and the relationship between the "total" and "external" surface area of the silica. The surface area properties of silica essentially determine their possible applications, or specific applications of silica (such as carrier systems or aggregates for ammunition mixtures) require certain surface properties. Therefore, US 6 013 234 proposes the manufacture of precipitated silica with a BET and CTAB surface area of 100 to 350 m2 / g. This silica is particularly suitable for incorporation into a bullet mixture, where the BET / CTAB ratio is between 1 and 1.5. EP 0 9 3 7 7 5 5 proposes various precipitated silicas having a BET surface area of about 180 to about 430 m2 / g and a CTAB surface area of about 160 to 340 m2 / g. These silicas are particularly suitable as support materials and have a BET / CTAB ratio of 1.1 to 1.3. EP 0 647 591 proposes a precipitated silica whose BET / CTAB table (2) (2) 200 400 920

EP 〇643 015 proposes precipitated silica, which can be used as a honing and / or thickening component in toothpaste 'whose BET surface area is 10 to 1 〇1112;' CT AB surface area is 10 to 70 m 2 / g, ie , BET / CTAB ratio is about 1 to 5.2 1. In tire manufacturing, aluminum-containing precipitated silica is often used as the material. Therefore, EP 0 9 8 3 9 6 6 proposes a precipitated silica containing aluminum, which has the following physical and chemical properties: BE but surface area 80--18m2 / g CTAB surface area 80-139m2 / g DBF number 100'320g / 100% A 12 Ο 3 content &lt; 5% This type of precipitated silica can be improved to be used as an elastic material. It has been found that precipitated silica containing aluminum and a high surface area of Beta E is particularly suitable as a binder (for example, for tires). [Summary of the Invention] The subject of the present invention is therefore Shendian Silica, whose BET surface area is in the range of 150-400m2 / g, and preferably in the range of 19-30m2 / g. The CTAB surface area is in the range of 140-350m2 / g. The content of 145_25〇nl2 / g is preferably 1 45 to 200 m2 / g, and the content of A12 0 3 is in the range of 0.2 to 5% by weight, and the content of 1 to 3% by weight is preferable, and can be adjusted to a better range, respectively. -6-(3) (3) 200400920 The precipitated silica according to the present invention preferably has a specific BET / CTAB surface area ratio. The BET / CTAB ratio can be in the range of 1.0-1.6, and preferably 1.2-1.6. In addition, this precipitated silica is characterized by a wk coefficient (the particle size distribution of particles that cannot be disintegrated by ultrasound is in the range of 1.0- 1 00 // the highest content and size of disintegrated particles <1 m The ratio between the highest content) is $ 3.4, preferably from 0.1 to 3.4, particularly preferably from 0.1 to 3.0 and / or the DBP absorption is 1 8 0-3 2 0g / 100g, of which 'the first The DBP of silica in one embodiment is within a preferred range of 200-320 g / 100 g, 250-320 g / 100 g, and 250-300 g / 100 g. In another implementation of the present invention, In the example, DBP is in the preferred range of 80-300g / 100g and 180-250g / 1 00g ° It is known that precipitated silica has a significantly higher wk coefficient and / or other peaks appear at the highest point of the particle size distribution. It has been known that the Wk coefficient is an index of the dispersibility of precipitated silica, and it is an index of the disintegration (dispersibility) of precipitated silica. The smaller the wk coefficient, the more easily the precipitated silica is dispersed, that is, the more particles are decomposed when incorporated into the rubber. The BET and CTAB surface areas of precipitated silica according to the present invention or their ratios are preferably within the following ranges: (4) (4) 200 400 920 BET [m 2 / g] CTA Γ m 2 / g] BET / CTAB t 1 95 145 1.34 200 15 0 1 -Ί Λ 1 .jj 2 10 149 1.4 1 2 8 0 14 7 1.90 3 15 1 48 2.13 3 5 0 15 0 2 .jj 3 70 1 52 2.43 Precipitated silicon according to the present invention The surface properties of the stones make them particularly suitable as a material for bullets. It can be determined by the modified Se a r s number V 2, and 値 is preferably between 5 and 35 m 1/5 g, and particularly preferably between 20 and 30 m 1/5 g. Another object of the present invention is a method for preparing precipitated silica with the following properties: BET surface area is within the range of 150-400m2 / g, CTAB surface area is within the range of 1-40-150m2 / g, and the AI2O3 content is within the range of 0.2-5% by weight. ' A) Water glass solution is filled into the container b) When stirring at 5 5-9 5 ° C, water glass and acidifier are weighed into the container at the same time for 30-100 minutes, c) acidified with acidifier to about pH 5, and d) filtered and dried -8- (5) (5) 200400920 where the 'aluminum compound is added in steps b) and / or c). The gravel prepared by the method according to the present invention has the aforementioned preferred parameters BET, CTAB, DBP, Al203 content and sears number. The concentration of the water glass solvent introduced in step a) may be the same as the concentration of the water glass used in step b) (eg, density i.34%, 27.4%, S! 02, 8.1% Na 2 0). Dilute solutions can also be used, such as: 0.5-10% S i Ο 2 and the corresponding 0.1 ° °. -3% N a 2 0. The components (g., Water glass and acidulant) added in steps b) and c) may have the same or different concentrations and / or addition rates. In the variation of the procedure, the component concentrations used in the two steps are the same, and the component feed rate in step c) is 1 2 5 4 0% of the feed rate in step b). Another—in a variation, the feed rate in step c) is only 3 0-1 0 0 in step b), and preferably 50-80%. In addition to water glass (sodium silicate solution), other silicates (eg potassium oxalate) can also be used. It is preferred to use sulfuric acid as the acidifying agent, but other acidifying agents' such as hci, hno3, H3P04, CH3COOH, or CO2 may also be used. The compound can be added in steps b) and c), or it can be added only in step b) or c), which is added as a solid, an aqueous solution, or an acidulant / aluminum compound mixed solution. The aluminum compound may be in the form of an aqueous solution of Ah (S〇4) 3, and it may also be A1 (N03) 3, A1C13, or Al (OAc) 3, and its concentration in water is 50-130 g / l 'to 70-110g / 丨 is better. Alternatively, a mixed solution of an acidifying agent / aluminum compound may be used. (6) (6) 200400920 Experts know the filtration and drying of silica according to the present invention, and can be known from, for example, the aforementioned patent documents. The silicic acid according to the present invention is preferably dried by a short-time drying method (such as: spray drying (optionally in a nozzle dryer), flash evaporation and / or rotary flash dryer).

Modified with one or more of the aforementioned organic silanes, granulated, non-granulated, honed, and / or unhoned, the aforementioned organic silanes can be used in an amount of 0.5 to 50 parts per 100 parts of precipitated silica (especially 1 To 15 parts / 1 Q 0 parts of precipitated silica) 'This will allow the anti-200400920 之间 between the precipitated silica and the organosilane to be sprayed and subsequent mixtures during the manufacturing mixture (in situ) or outside the manufacturing period. Toughening treatment, by mixing the organosilane with the silica suspension and subsequent drying and toughening (for example, according to DE 3 4 3 7 4 7 3 and DE 1 9 6 0 9 6 1 9) or according to DE 1 9 6 0 9 6 1 9 or DE-PS 4 0 04 7 8 1. All difunctional silanes (which can be coupled to silanol-containing compounds on the one hand and to polymers on the other hand) are basically suitable as organosilicon compounds. The typical amount of the organosilicon compound is 1 to 10% by weight relative to the total amount of precipitated silica. Examples of these organosilicon compounds are: bis (3-triethoxysilylpropyl) tetrasulfide, bis (3-triethoxysilylpropyl) disulfide, vinyltrimethoxysilane, ethylene Triethoxysilane, 3 -fluorenylpropyltrimethoxysilane, 3 -ylpropyltriethoxysilane, 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxy Silane. Other organosilicon compounds are described in W099 / 09036, EP 1 108 231, DE 101 37 809, DE 101 6 3 94 5, DE 1 02 2 3 658. In a preferred embodiment of the present invention, bis (3-triethoxysilylpropyl) tetrasulfide and bis (3-triethoxypropyl) disulfide can be used as the silane. Use of silica according to the present invention in a projectile mixture. Silane according to the present invention may be mixed into the bomb in the form of powder, microparticles or granules with or without silane modification in an amount of 5 to 200 parts per 100 parts rubber It is used as a reinforcing material in rubber mixtures, tires or vulcanizable rubber mixtures. -13-(10) (10) 200400920 The aforementioned one or more silanes can be added to the ammunition with silica. Here, the reaction between the aggregate and the sand ends occurs when the temperature is mixed (modified in situ) or In the modified form (for example, DE-PS 4 0 4 7 8 1), that is, the reaction participants reacted when they did not actually make the reaction. In addition to the mixture (with or without the silica according to the invention, with or without the organosilanes according to formulae XI to 111), the bomb may additionally contain one or more reinforced concrete. In the first example, a blend of carbon black (eg, furnace black, gas, flame black 'acetylene carbon black) and silica (with and without silane) according to the present invention, (Eg, clay, silicon-containing chalk), blends of other commercially available silicas, and silicas according to the present invention. The blending ratio with the organosilane here matches the desired properties of the final rubber mixture. It is possible to make the ratio between the silica according to the present invention and the other aforementioned materials to be 5 to 95% ', which is also within this system. In addition to the silica according to the invention, organosilanes and other materials and elastomers are other important constituents of rubber mixtures. The silanes according to the invention can be used for all elastomers which can be accelerator / sulfur crosslinked and also peroxide crosslinked. Examples of these are natural and synthetic, blended or non-blended bullets, which are single polymers or with other bullets (eg natural rubber, butadiene rubber, isoprene rubber, butadiene styrene Blends of rubber (especially SBR, made by solution polymerization), butadiene acrylonitrile rubber, butyl rubber, terpolymer of ethylene / propylene / non-conjugated diene). The following additional rubbers can also be included in the consideration of rubber mixtures with the aforementioned rubbers: carboxylate rubber, epoxy rubber 'trans-polypentenamer' halogenated butyl rubber-14-(11) (11) 200400920 rubber, from 2 _Chloroprene rubber, ethylene / vinyl acetate copolymer 'Ethylene / propylene copolymer and chemical derivatives of selected natural rubber and modified natural rubber. Similar known ones are other components, such as: suitable amounts of plasticizers, AM activators, pigments, antioxidants and processing aids. Silica (with or without silane) according to the invention is used in all rubber applications, such as · tires, conveyor belts' seals, v-belts, hoses, soles, etc. Another object of the present invention is a projectile mixture, especially a vulcanizable rubber mixture, containing silica according to the present invention in an amount of 5 to 200 parts per 100 parts of a projectile or rubber. The processing of the silica and the manufacture of the mixture containing the silica are carried out in an internal mixer or open-drum honing machine in a manner commonly used in the rubber industry. Available forms or forms of use may be powders, granules or granules. Here, the silica according to the present invention is not different from the known white beet. To achieve a good combination of polymer mixtures, the dispersion of precipitated silica in the matrix (polymer) has a decisive effect. Use of Precipitated Silica According to the Invention for Paper Coating The inks currently used (for all types of so-called inkjet printing and related methods) are mostly anionic in nature. Therefore, the particles have at least a part of a cationic surface in terms of fixed colorants (dye and / or pigment), color brightness, print clarity, and print depth on the surface of the medium to be printed or in the surface range thereof. Currently, silica and silicate are commonly used in the aforementioned coating blends (eg: (12) (12) 200 400 920 paper, film coating). The activation modification of these silicas and silicates (ie, cationic sites that can be used (EP 0 49 2 2 6 3)) occur on their surfaces, in accordance with the current requirements for commonly used anionic colorants. Because of the effect of built-in metal ions on the refractive index, the use of transparent media (such as silica / silicates for foils in coatings) has additional advantages. Therefore, the object of the present invention is also to use precipitated sandstone according to the present invention or to manufacture precipitated silica as a paper-making or paper-coating additive by the method according to the present invention. In particular, the precipitated silica according to the present invention can be used for coating paper (for example, inkjet paper) and other printing media (for example, completely immersed film or printable fabric). The precipitated silica according to the present invention may be not only a dried and optionally ground product, a ground product, but also a dispersion. In the case of precipitated silica according to the present invention, the dispersed filter cake is particularly advantageous when it is used for coating applications of pulp or printable media to achieve further processing or cost advantages. When used in paper making, pigments (Ti〇2, Fe oxide, A 丨 metal filter cake) can be used in auxiliary agents (commonly used in the paper industry, such as: polyalcohol, polyvinyl alcohol, synthetic or natural polymers) ( It may also be an undoped silica, that is, an aluminum-free additive (precipitated silica or aerosol) is mixed with the dispersion of precipitated silica according to the present invention. The physical and chemical data of the precipitated silica according to the present invention were determined by the following methods: BET surface area Area meter, Strohlein, according to IS05794 / (13) 200400920 C T A B surface area at ρ Η 9, according to Ja n z e n and Kraus in Rubber ogy 44 (1971) 1287

Three repeated tests were 60 seconds each, and the waiting time between each silica sample was 0. From the raw data curve, the software calculates the particles based on the volume distribution (taking into account Mie theory and the optical model of Fraunhofer). Particle size distribution. Basically, the distribution curves of the two statistical methods found that the A model is between 0 and 1 m (up to about 0.2 m) and the B model is between 1 and 1 0 0 # m (up to about 5 m). μm). According to Figure 1, the wk coefficient can be determined from this. The value shown is the average 値 of 6 measurements. The basic point here is the energy input via ultrasonic waves, which represents the simulation through industrial mixers in the tire industry. The energy input by the mechanical force. This curve shows that the first particle size distribution has a maximum 値 in the range of 1. 0 // m-and another maximum 値 in the range cl.O / zm. Peaks in the range of 1.0-100 # m It is a part of silica particles that have not been pulverized after ultrasonic treatment.

The second peak of a much smaller particle size (&lt; 10 μm) indicates that Sonic Division-22-(19) (19) 200400920 Silica particles that have been crushed during the processing period. These very small particles are well dispersed in the rubber mixture. The wk coefficient is the undisintegrated particles (B) (its largest値 appeared in the peak heights and collapses in the range of 1.0-1000 μm (B '). The ratio between the peak heights of the resolved particles (a) (the largest value of which occurs at &lt; 1 · 0 # m (A)). The modified Sears number of silica (the modified Sears number (hereinafter referred to as The Sears number V2) is an indicator of the number of free hydroxyl groups, which can be determined by titrating stone spar with a potassium hydroxide solution at pH 6 to pH 9.
