The present invention has simple technological process and low cost, and is suitable for industrial production.
Description
Technical field
The invention belongs to a kind of method for preparing universal pitch charcoal fibre.
Background technology
The research of pitch based carbon fiber originates from the sixties in 20th century, sends out the manufacturing technique of understanding pitch based carbon fiber by Japanese large space between muscles China fir youth, and has realized suitability for industrialized production in 1970 by Wu Yu chemical company.It is the pitch based carbon fiber of raw material that U.S. associating carbide company also successfully developed with asphalt in 1970, and nineteen eighty-two begins to drop into suitability for industrialized production.The technical strength of Japanese iron and steel and Japan petroleum two major companies has been inherited by Japan graphite fibre company, established " Granoc " asphalt carbon fiber company jointly in nineteen ninety-five, actively develop the application study of pitch based carbon fiber, properties of product have not only been improved, and developed a lot of new varieties, as low modulus type, middle modulus type, aerospace grade product etc.
The raw material of pitch based carbon fiber is comparatively extensive, coal and PETROLEUM PROCESSING accessory substance and synthetic asphalts etc. all can be used as the raw material of asphalt carbon fiber, it be through pitch refining, spinning, do not melt, charing or graphitization and the special fibre that makes, having the characteristic of low-density, high-tensile strength and modulus, high temperature resistant, a series of excellences such as thermal coefficient of expansion is little, resist chemical, high conduction and heat conduction, is dual-use indispensable new material.The charcoal fiber often joins in the matrixes such as resin, metal or pottery, charcoal, cement as the application of composite reinforcing agent, constitutes the charcoal fibre reinforced composites, is a kind of extremely useful structural material.Along with the diversification of charcoal fiber applications development in recent years, its Application Areas is constantly widened, and the charcoal fiber year growth rate of demand reaches 20%, and abroad each main charcoal fiber production merchant enhances production capacities one after another, and the demand of global charcoal fiber in 2010 will be above 100,000 tons.
The research of China's asphalt carbon fiber is started late, and also has certain gap in exploitation, production and application facet with comparing abroad.Although universal pitch charcoal fibre (GPCF), the high-performance asphalt carbon fiber (HPCF) of development have reached external like product level on performance, all do not form production capacity.Along with Chinese economic development, charcoal fiber applications field constantly enlarges, and market demand will further increase, and owing to low, its cheap market price of pitch based carbon fiber production cost, development prospect will be very considerable simultaneously.
Among the preparation method of number of patent application 00123361.0 petroleum asphalt-base common carbon fiber material, adopting ethylene cracking tar is feedstock production high softening-point spinning asphalt and refining carbon fiber asphalt raw material, and this method is ethylene cracking tar to be produced the high softening point bitumen of retinasphal and 200～250 ℃ by normal pressure, reduced pressure distillation process; Retinasphal carries out thermal polycondensation again under anoxybiotic, gas such as carry at specified conditions and separating reaction just is refined into the carbon fibre asphalt raw material.98117508.2 1 kinds of number of patent applications are produced in the method for carbon fibre asphalt and acicular petroleum coke simultaneously, and the employing ethylene bottom oil is a raw material, prepares the carbon fibre asphalt raw material by heat treatment and vacuum flashing.These two kinds of method technological process complexity, the cost height requires also high to equipment simultaneously.
Summary of the invention
The object of the present invention is to provide the preparation method of the universal pitch charcoal fibre that a kind of technological process is simple, cost is low.
This method is that ethylene bottom oil passes through heat of oxidation polycondensation and nitrogen purging or oxidative polycondensation and the preparation of decompression distillation two-step method.Ethylene bottom oil is put into reactor, and bubbling air carries out oxidative polycondensation or feeds nitrogen purging, and when temperature is raised to designated value constant temperature a period of time, carries out decompression distillation in this temperature then, makes asphalt carbon fiber material asphalt.With this pitch by melt spinning, do not melt, charing makes the asphalt carbon fiber.
Preparation method of the present invention is following step:
(1) with carbon residue be 7～10%, ash content is that 0.01～0.04% ethylene bottom oil is put into reactor, bubbling air stirs simultaneously, the quality of ethylene bottom oil and the ratio of air mass flow are 1800～2000g: 0.2～0.4m
3/ h is that 0.5～1.5 ℃/min is warmed up to 260～330 ℃ of constant temperature 1～7 hour with heating rate, is warming up to 320～380 ℃ under nitrogen protection, and constant temperature 0.5～4 hour makes preparation charcoal fiber raw material spinning asphalt;
(2) with the spinning material pitch that makes by melt spinning, do not melt, charing makes universal pitch charcoal fibre.
Aforesaid spinning temperature is for being 290～360 ℃, and spinning pressure is 0.2～1.0MPa; Fusion temperature is not 260～320 ℃, and fusing time is not 3～11 hours; Carbonization temperature is 900～1200 ℃, and heating rate is 1～3 ℃/min.
Step (1) is warming up to 320～380 ℃ under nitrogen protection, constant temperature can also carry out decompression distillation 10～30 minutes after 0.5～4 hour, makes preparation charcoal fiber material asphalt.Advantage of the present invention and effect are as follows:
The present invention is logical to have prepared the universal pitch charcoal fibre spinning asphalt with ethylene bottom oil by heat of oxidation polycondensation and nitrogen purging or heat of oxidation polycondensation and decompression distillation two-step method, and prepared universal pitch charcoal fibre with this asphalt stock, preparation technology is simple, is fit to suitability for industrialized production.Prepared asphalt stock carbon residue height, little, the good spinnability of discreteness, continuous length reaches more than 50000 meters, even also can fracture of wire 1250 rev/mins of high rotating speeds, the diameter of charcoal fiber be at 10～14 μ m, intensity is 800～1100MPa.
