視所形成之加工物及用以媒合瀝青所使用之溶劑而定 ,該製造方法可要求以適合於本製備方法之溶劑代替媒合 •瀝青。此步驟爲已知之溶劑交換,可由幾種方法達成。一 種方法:要求乾燥成溶劑化物之瀝青而趕走溶劑,接著以 合適之溶劑再媒合該瀝青。而另一種方法提供添加一種具 有高於起始媒合瀝青之沸點之溶劑至成溶劑化物之瀝青中 。然後,加熱此混合物至沸騰而移除較低沸點之溶劑(從 包含較髙沸點溶劑之成溶劑化物之瀝青中離開)。不管何 種方法,典型之製造溶劑將具有約8至約12且可能更高 之溶解度參數。該製造溶劑(非消耗性地)可包括下列溶 劑之一或多種溶劑:甲苯,苯,二甲苯,四氫萘,四氫呋 喃,氯仿,庚烷,吡啶,喹嚀,經鹵化之苯,氯氟苯,及 2至4環芳香族之溶劑,及其部份烷圖化與氫化之衍生物 Ο 一旦該成溶劑化物之瀝青包含一種適合該製造方法之 溶劑,其可藉由在此技藝中已知之方法形成爲碳加工物。 目前,最普通之碳加工物爲碳纖維。 在從成溶劑化物之瀝青中紡織碳纖維之方法中,部份 溶劑將從產品纖維中遺失。在拉絲之後,任何剩餘之溶劑 藉由乾燥纖維而立即移除。溶劑之損失產生具有至少 2 8 0 °C軟化點之碳纖維。另外,所得之纖維將具有高於 纖維之拉絲溫度之熔點。最終,視起始化之進料瀝青而定 ,所得之纖維在碳化之前將不需要額外之處理。

熱纖維而達成碳化作用。至於纖維發展之碳化作用,纖維 之軟化溫度上昇,允許碳化反應之溫度相對增加。然而, 在碳化反應期間,該纖維從來不會加熱超過其軟化點。對 於具有高於5 0 0 °C軟化點之纖維可在每分鐘2 0 °C之上 昇或更快但不會軟化該纖維之速率下加熱。一般,在 6 0 0 °C加熱,碳化作用完成之。然而,可在甚至較高之 溫度下處理該纖維。 對於具有約2 8 0 °C至5 0 0 °C之間之軟化點之瀝青 ,在碳化之前較佳進行氧化安定化作用。另外,在某些環 境之下,可能需要氧化安定化具有高於5 0 0 °C軟化點之 瀝青。 本發明之一利益爲在相對高溫與低氧濃度中,能夠快 速地氧化安定瀝青且/或由該瀝青所製成之碳加工物。更 明確而言,安定化作用可在高於加工物形成溫度之溫度下 及包含低於5 %氧之大氣中完成之。本發明超過先前氧化 安定化作用之方法之利益由例2與圖1論證之。圖1比較 一種傳統瀝青與成溶劑化物之瀝青之氧化安定化作用。如 圖1之論證,在氧化安定化作用之前,成溶劑化物之瀝青 不需冷卻,且安定化作用發生於較高溫度較短週期時間。 因此,本發明提供一種重要之安全利益,其安全性超過在 氧化安定化作用時藉由排除燃燒危險性之先前技藝。 本紙張尺度適用中國國家標準(CNS ) A4規格(210 X 297公釐) (請先閲讀背面之注意事項再填寫本頁) 1

%氧之大氣下,在足夠短之週期時間進行時 是需要安定化作用。 一旦經拉絲之纖維碳化,本發明之碳纖維可從連續各 向同性至連續各向異性變化之。然而,出現在這些纖維中 任何各向異性區域之主要部份不具有中間物瀝青碳纖維之 髙度延長範圍特徵。這些纖維具有相當於傳統各向同性瀝 青纖維之張力强度。爲了達成包含各向異性區域之纖維程 度,與完全各向同性之纖維比較,其具有經改良之熱與電 特性。

Description of the Invention (1) Background and Abstract This application is about the invention of high melting point isotropic asphalt which can be converted into solvate isotropic asphalt to reduce The actual melting point of low bitumen. The solvated bitumen prepared by the method of the present invention can be spun into fibers. It requires little or no stabilization. For the traditional method of spinning non-solvated isotropic bitumen, It is well known. Currently Ku re ha Chemical Industries is a leading pioneer with a capacity of 900 tons per year. Other manufacturers include Ashland Oil and Kawasaki Steel. Isotropic carbon fibers are often used as reinforcing materials for concrete structures. In this view, carbon fiber must be comparable to steel and glass fiber. Therefore, it is necessary to provide the lowest possible cost of carbon fiber. In the method of manufacturing carbon fiber, the slowest and most costly step is to make the textile before the carbonization of the fiber. The stabilization of the fibers (usually by oxidation). The stabilization step is required to prevent the fibers from melting. During the carbonization process, the temperature that has occurred exceeds the printing of the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) 3 5 0 ° C And usually higher than 1000 ° C. In order to reduce the time and cost of this step, it is preferred to make fibers from high melting point asphalt. Prior to the present invention, however, asphalt that melted above the textile temperature was not available. Therefore, an object of the present invention is to provide a method for preparing carbon fibers, which method does not require oxidation before stabilization. In addition, the present invention provides a solvated isotropic pitch that has a fluid temperature of at least 40 ° C, which is lower than the melting point of the same pitch in a non-solvated state. In addition, the present invention provides a solvated bitumen that can be woven into fibers. The bitumen is devolatilized at a temperature equal to or greater than the textile temperature.

Isotropic isotropy Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics and Preparation (please read the precautions on the back before filling this page). The preparation of isotropic asphalt that is solvated initially selects a suitable feed asphalt. Suitable for use in the present invention The pitch will have a composition of about 88% to 96% by weight of carbon, up to about 12% by weight of hydrogen and not more than 6% by weight of sulfur, oxygen, nitrogen, or other components. Preferably, the pitch molecules are The main part is aromatic. In addition, the asphalt should have a low concentration of mobile insolubles. It is preferred that the asphalt has a mobile insoluble of less than 20%. If necessary, it is filtered before or after solvation. The bitumen reaches the level of appropriate insoluble matter. The bitumen is dissolved with an organic co-solvent, such as toluene, chloroform or tetrahydrofuran, followed by physical separation of the dissolved insoluble matter. These flowing insolubles typically contain pitch impurities such as ash and inorganic compounds. In some cases, very high melting organic compounds can also be removed as flowing insolubles. Generally, pitches having less than 30% by weight of quinoline insoluble matter (Q I) will be appropriate; however, preferred pitches should have Q I between 0% and 10% by weight. Typically, these pitches have a melting point range from about 100 ° C to about 300 ° C. Another parameter for a suitable pitch is the degree of insolubility in a solvent, such as toluene. Generally, the bitumen must contain at least 5% by weight of toluene insolubles to produce an isotropic pitch product that becomes a solvate. Preferably, the asphalt will contain at least 20% by weight of toluene-insoluble matter. Compared with flowing insolubles, toluene insolubles usually require more concentrated solvents to become soluble organic compounds. Asphalts that meet the above requirements include the Chinese paper standard (CNS) A4 specification (210 > < 297 mm) for the paper size. A7 B7 printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. Medium, petroleum and ethylene tar pitch. Commercially available bitumen includes Ash land A240 asphalt, heat treated Ashland A240 and Ashland Aerocarb asphalt. The selection of a suitable solvating solvent is very important in the present invention. Typically, suitable solvents have a solubility parameter ranging from 8.0 to 1 1.0. The term * solubility parameter is defined as 1 where H v: = heat of evaporation R = Mohr gas constant T = temperature (° κ) V = Mohr volume For a discussion of solubility parameters, please refer to the non-electrolyte solubility olubilitv of Nnn- Electrolvtes), 1948, J. Hildebra. Nd and R. Scott, incorporated herein by reference. Useful solvents found in the present invention include: benzene, toluene, xylene, tetrahydrogen. In addition, other substituted aromatic solvents such as heteroaromatics (e.g., quinoline and pyridoxine) and 1 to 3 ring aromatic compounds and their partially hydrogenated or alkylated derivatives can be used in the present invention. Substituted aromatic aromatic blends and paraffin solvents such as heptane are also suitable in the present invention. In general, a suitable solvent will produce a quarter to twice the amount of heavy asphalt insoluble matter (the amount of heavy asphalt insoluble matter prepared from toluene). For the purpose of the present invention, the solubility is measured at room temperature by combining one gram of asphalt and a solvent of 25 m Θ at room temperature.

Description of the invention (8) 〇 The method of the present invention combines the asphalt and the solvent as described above to provide a solvate-oriented solution Homosexual asphalt. According to the method of the present invention, the isotropic pitch is mixed with a solvent at a temperature sufficient to convert all phases in the mixture to a liquid state and at a pressure sufficient to prevent boiling in a period of about one hour. After mixing, the asphalt / solvent system is precipitated and cooled. During this step, phase separation occurs, producing a liquid solvent phase and a solvated asphalt phase. Depending on the equipment, the completion time of precipitation is about 5 to 30 minutes. If necessary, a mechanical method such as centrifugation can be used to accelerate the phase separation. After phase separation, the recovered solvated asphalt is either liquid or a liquid that can cool the mixture, and the recovered asphalt is a precipitated solid. In any case, a more convenient recovery method will be suitable, for example: gently decanting the liquid phase or filtering to remove solid solvated asphalt. The bitumen and solvent phases can be continuously recovered as a solvate in the liquid state. If necessary, the asphalt recovered in the liquid state, which has been recovered as a solvate, can be filtered to remove contaminants. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) by forming the same combination of isotropically fed asphalt and solvent (at lower temperatures, the solvent phase is liquid The solvated asphalt phase is solid) to obtain a solvated asphalt. When using this method, the solid solvated pitch can be recovered by conventional methods such as filtration. The properties of the non-volatile portion of the solvated asphalt can be measured at a temperature of about 150 ° C by removing the solvent by drying the solvated asphalt for about 60 minutes. After drying the asphalt, apply the Chinese National Standard (CNS) A4 specification (210X297 mm) at the paper size of the inert gas pressure. Printed by A7 __B7_ 'in the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. The softening point and melting point are determined by heating on a thermal stage microscope at a rate of about 5 ° C / minute. After the solvent is removed, the bitumen of the present invention will normally have a softening point of at least 280 ° C. At temperatures greater than 500 ° C • Harder dried asphalt will soften; however, these asphalts will not melt when heated at 5 ° C / min in an inert gas. These asphalts are considered to be self-stabilizing, so they will be carbonized directly to carbon processed products when continuously heated. II. Solvated Isotropic Asphalt ‘The solvated isotropic pitch of the present invention provides several important benefits over unsolvated isotropic pitch. Generally, the solvated asphalt will contain from about 5 weight percent to about 4 weight percent solvent. In addition, the solvated pitch has at least 50% by weight of toluene-insoluble matter and may consist of up to 40% by volume of optical anisotropy. Once the solvent is removed from the pitch, the anisotropic content can be increased. The isosolved bitumen of the present invention has a fluid temperature of at least 40 ° C, in some cases exceeding 100 ° C, which is lower than in the unsolvated state, meaning dry asphalt, the same asphalt Of melting point. III. Method for preparing carbon processed product The present invention also provides a method for manufacturing a carbon processed product from a solvated isotropic pitch. In particular, the present invention provides a method for producing carbon fibers from a solvated isotropic pitch. The method of manufacturing carbon processed products from solvated isotropic pitch is to apply the Chinese National Standard (CNS) A4 specification (210X2.97 mm) from the solvated paper size (please read the precautions on the back first) (Fill in this page again) Strike-Book 12 I. Printing of A 7 _____ £ 7_ by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs, V. Description of Invention (10) Isotropic asphalt. Depending on the formed processed product and the solvent used to mediate the asphalt, the manufacturing method may require that a solvent suitable for this preparation method be used in place of the mediated asphalt. This step is known as solvent exchange and can be achieved by several methods. One method: require the asphalt to be dried to a solvate to drive off the solvent, and then re-mediate the asphalt with a suitable solvent. Yet another method provides the addition of a solvent having a boiling point higher than the starting mediated pitch to the solvated pitch. The mixture is then heated to boiling to remove lower boiling solvents (leaving from solvated asphalt containing higher boiling solvents). Regardless of the method, a typical manufacturing solvent will have a solubility parameter of about 8 to about 12 and possibly higher. The manufacturing solvent (non-expendable) may include one or more of the following solvents: toluene, benzene, xylene, tetrahydronaphthalene, tetrahydrofuran, chloroform, heptane, pyridine, quinone, halogenated benzene, chlorofluorobenzene And 2- to 4-ring aromatic solvents, and their partially alkylated and hydrogenated derivatives. Once the solvated bitumen contains a solvent suitable for the manufacturing method, it can be obtained by using a solvent known in the art. The method is formed into a carbon processed product. At present, the most common carbon processed product is carbon fiber. In the method of weaving carbon fibers from solvated pitch, some of the solvent will be lost from the product fibers. After drawing, any remaining solvent is removed immediately by drying the fibers. The loss of solvent produces carbon fibers with a softening point of at least 280 ° C. In addition, the resulting fiber will have a melting point that is higher than the fiber drawing temperature. Finally, depending on the starting feed pitch, the resulting fibers will not require additional treatment before carbonization.

Packing.-Order _ Printed by A7, Employees' Cooperatives, Ministry of Economic Affairs ______B7_ '1 V. Description of the invention (11) The dried fibers with a softening temperature greater than 350 ° C starting temperature need not be stabilized before carbonization. The preferred fibers are those with a softening point above 500 ° C. When the temperature is slightly lower than the softening point of the fiber, the fiber is heated to achieve carbonization. As for the carbonization of fiber development, the softening temperature of the fiber rises, allowing the temperature of the carbonization reaction to increase relatively. During the carbonization reaction, however, the fiber never heats past its softening point. For fibers with a softening point above 500 ° C, heating can be performed at a rate above 20 ° C per minute or faster but without softening the fiber. Generally, carbonization is completed by heating at 600 ° C. However, the fibers can be treated at even higher temperatures. For bitumen with a softening point between about 280 ° C and 500 ° C, oxidative stabilization is preferably performed before carbonization. In addition, under certain circumstances, it may be necessary to oxidize and stabilize asphalt with a softening point above 500 ° C. An advantage of the present invention is that it can rapidly oxidize stable asphalt and / or a carbon processed product made of the asphalt at relatively high temperature and low oxygen concentration. More specifically, stabilization can be performed at temperatures above the temperature at which the workpiece is formed and in an atmosphere containing less than 5% oxygen. The benefits of the present invention over previous methods of oxidative stabilization are demonstrated by Example 2 and Figure 1. Figure 1 compares the oxidative stabilization of a conventional pitch with a solvated pitch. As demonstrated in Figure 1, prior to oxidative stabilization, the solvated asphalt does not need to be cooled, and stabilization occurs at higher temperatures and shorter cycle times. Thus, the present invention provides an important safety benefit that exceeds the prior art by eliminating the danger of combustion during oxidative stabilization.

Description of the invention (12) IV. Carbon fiber formation from solvated asphalt. The solvated asphalt melts above the wire drawing temperature. After the solvent is removed, the fibers of the present invention are typically infusible. As a result, the fibers of the present invention often do not require chemical stabilization before carbonization. However, in some cases stabilization is required: in an atmosphere containing only about 2 to 5% oxygen, stabilization is required when performed in a sufficiently short cycle time. Once the drawn fiber is carbonized, the carbon fiber of the present invention can be changed from continuous isotropic to continuous anisotropic. However, the major part of any anisotropic region appearing in these fibers does not have the characteristics of the extended range of the pitch pitch carbon fiber. These fibers have a tensile strength equivalent to that of conventional isotropic asphalt fibers. In order to achieve a degree of fiber containing anisotropic regions, it has improved thermal and electrical characteristics compared to fully isotropic fibers. The following examples illustrate the invention. Unless otherwise specified, all parts and percentages are by weight. Applicants do not want examples to limit this theory. The true scope of the invention is based on the scope of the attached patent application. Example 1 In a stirred pressure cooker, A 2 40 homogeneous asphalt sample (8% by weight toluene-insoluble matter) was mixed at a ratio of 1 g of asphalt per 8 cc of solvent: commercially available from Ashland Chemical Company, Columbus, Ohio This paper size applies to China National Standards (CNS) 8-4 specifications (210X 297 mm) (Please read the notes on the back before filling out this page)-Binding and ordering printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 5. Description of the invention (13)) and toluene. Fill the pressure cooker with nitrogen, drain briefly and seal. During 80 minutes, the mixture was heated until a temperature of 2 3 ° C was reached. The mixture was kept at 230 ° C for 10 minutes and stirred. The mixture was kept at 2 3 3 ° C for 15 minutes without stirring, and then cooled. During heating, the maximum pressure generated in a closed pressure cooker was 175 ps i g 〇 solid asphalt was recovered from the bottom of the pressure cooker, and the yield of the asphalt was calculated to be 6.4%. The pitch was analyzed by an optical microscope and found to contain 5% of intermediates in the form of small spheres. Dry the solid bitumen sample by heating at 360 ° C for 30 minutes under air. This step removes 28.2% of volatiles from the bitumen. Under the microscope thermal stage, under nitrogen, the heating rate is increased by 5 ° C per minute to 650 ° C. The dried asphalt will not soften or melt. Example 2 A solvate pitch was prepared by combining Aerocarb 80 (30% by weight of toluene-insoluble matter) with toluene at a ratio of 1 g pitch to 8 πθ toluene. The mixture was stirred at 230 ° C for 1 hour, allowed to settle for 15 minutes, and then cooled. A dense solid solvated asphalt layer was recovered from the bottom of the container with a yield of 54%. The solvated asphalt is sufficiently homogeneous, with only a fine sphere type with a non-isotropic direction of 5 to 10 ||%, and some larger spheres. Dry the solvated asphalt sample at 150 ° C for 1 hour under air to remove the solvent. After drying, the asphalt loses 22.1 weight. The paper size is in accordance with China National Standard (CNS) A4 (210X297 mm) _ (Please read the precautions on the back before filling this page):,-r7 ~-.. >} /, -I-11--1 I —1 I —Clothing — — IIII Order IIII --- Printed by A7 __B7__ 'in the Consumer Consumption Cooperative of the China Standards Bureau of the Ministry of Economy . Under emptying, the asphalt was further heated to 360 ° C to remove another 4.9% of volatiles. This additional loss appears to be due to the removal of any remaining solvents and the loss of some light oil. Analysis of this sample revealed a total of 52% by volume anisotropy. This argument demonstrates that the isotropic cyanocyanate that is a solvate produces additional anisotropy due to the loss of solvent. The temperature of the solvated homogeneous pitch is determined in a small pressure cooker by measuring the stirring resistance. The toluene-solvated bitumen is heated to a temperature above its fluid temperature, in this case 2 3 5 and then slowly cooled at about 1 ° C per minute. Using this method, the toluene-solvated asphalt reaches a viscosity of 600 Opoise at 191 ° C. Therefore, the fluid temperature of the solvated asphalt is 4 2 ° C, which is lower than the melting point of the Aero car b feed asphalt. Later, by using a thermal stage microscope, the solvent and softening point of the solvated asphalt after the removal of the solvent were determined. As previously defined, softening occurs when the sharp angle of the asphalt particles first becomes round. Melting occurs when the first observable flow of the softened asphalt is seen. Using these procedures and definitions, the dried solvated asphalt softens at 3 2 3 ° C and melts at 3 2 8 ° C. The melting point of the dried solvated asphalt is 95 ° C, which is higher than the Aerocarb 80 feed asphalt. Notably, the difference in melting point between the fluid temperature of the dried solvated bitumen and the solvated bitumen was at least 137 ° C in this experiment. In order to demonstrate the improved stabilization characteristics of the dried unsolvated asphalt, the dried solvated asphalt sample and A e r oc a r b 80 were oxidized. Two kinds of asphalt samples are crushed into particles of 10 to 200 microns, and the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _ ·!

Silkworm Explanation (I7) Example 3 This example demonstrates that the benefits of spinning the carbon fiber from the solvated isotropic pitch of the solvate of Example 3 outweigh the benefits of feeding asphalt spinning fibers from Aer Dear b. Before spinning from the solvated pitch of Example 3 into fibers, the solvated pitch was redissolved with tetrahydrogen. The re-dissolving step includes drying the solvated asphalt to remove toluene, and then combining the asphalt with tetrahydrogen (in a ratio of 7: 2 = asphalt: solvent). Tetrahydrous solvated asphalt was equilibrated at 230 ° C for 30 minutes. The redissolved asphalt has a fluid temperature of 161 ° C. Printed by the Consumers' Cooperative of the Central Bureau of Standards, Ministry of Economic Affairs (please read the precautions on the back before filling this page) The solvated asphalt and Aerocarb feed asphalt are melted and woven into fibers. At 18 ° C, the solvated pitch forms fibers of 50 to 65 microns. Textiles made from solvated pitch contain the remaining solvent. Under nitrogen, these fibers are heated to 290 ° C in two minutes, and then heated at a rate of 5 ° C / minute to determine the softening point and melting point of the woven fiber. Softening, as indicated by the rounded edges of sharp edges and the bending of some fibers, was observed at 30.2 ° C. Melting, as indicated by the rounding and swelling of the edges of the fibers and the melting of the fiber joints, was observed at 3 5 3 ° C. It must be noted that fibers made as weaving are usually easier to soften and fibers that dry less carefully melt slowly. In contrast to the present invention, AerDcarb feed bitumen needs to be heated before spinning into 40 to 6 G micron fibers To 298 ° C ° These woven fibers are heated to 200 ° C in two minutes, and then heated at a rate of 5 ° C per minute. These fibers are softened at 2 7 ° C and the Chinese national standard (CNS) A4 specification (210X297 mm) _ 20-B7 is applied at the paper size. V. Description of the invention (is) 2 3 4 ° C melting. In addition, both groups of fibers are stabilized. The solvated pitch fiber was stabilized at 270 ° C by exposure to 2% oxygen in nitrogen for 60 minutes (83 ° C higher than the textile temperature). The fiber was then heated to 650 ° C under nitrogen at 20 ° C per minute. The fiber does not soften or melt. Aero car b feed pitch fibers were exposed to the same oxygen-containing gas at 19 5 ° C for 60 minutes. Note: Due to the melting point of these fibers, lower temperatures are required. Under nitrogen, at a rising temperature of 20 ° C per minute, these fibers softened at 248 ° C and melted at 258 ° C. As shown in Table 2, these results clearly demonstrate that solvated asphalt is easy to improve stability and achieve lower textile temperatures.
