Description
Technical field
The invention belongs to a kind of raw material of producing basalt fibre and preparation method thereof that is used to, relate in particular to a kind of raw material matching component of producing basalt fibre and preparation method thereof that is used to.
Background technology
Continuous basalt fiber (CBF) be with natural volcano extrusive rock as raw material, its broken back is added in melting furnaces, after 1450 ℃～1500 ℃ fusions, the continuous fibre of making by the platinum rhodium bushing.With CBF is to strengthen the matrix material that body can be made into various excellent performances, can be widely used in military project and civil areas such as fire-fighting, environmental protection, aerospace, military project, car and boat manufacturing, engineering plastics, building, so CBF is described as the novel material of 21 century.CBF is the fourth-largest hi-tech fiber of carbon fiber, aramid fiber and superhigh molecular weight polyethylene fibers of continuing, and alternative carbon fiber, aramid fiber under many conditions are in some occasion even not worse than above-mentioned two kinds of fibre properties.
The high-performance of basalt fibre and goods thereof is in particular in the following aspects: (1) significant resistance to elevated temperatures and thermal shock resistance.The use temperature scope of CBF is-260 ℃～720 ℃, and this temperature is higher than aramid fiber, alkali-free E glass, asbestos, rock wool, stainless steel far away, near silica fibre, aluminium silicate fiber peacekeeping ceramic fiber; Good thermal shock stability remains unchanged under 500 ℃ of temperature, and original weight only loses 3%[5 in the time of 900 ℃].(2) lower heat-conduction coefficient.The heat-conduction coefficient of CBF is 0.031W/mK～0.038W/mK, is lower than aramid fiber, aluminum silicate fiber, alkali-free glass fiber, rock wool, silica fibre, carbon fiber and stainless steel.(3) high Young's modulus and tensile strength.The Young's modulus of CBF is: 8100kg/mm
2～11000kg/mm
2, be higher than alkali-free glass fiber, asbestos, aramid fiber, polypropylene fiber and silica fibre.The tensile strength of CBF is 3000～4800MPa, and is all higher than large-tow carbon fiber, aramid fiber, PBI fiber, steel fiber, boron fibre, sapphire whisker, suitable with the S glass fibre.(4) chemical stability is good.The acid resistance of CBF and alkali resistance are all good than aluminoborosilicate fiber.Its weather resistance, weathering resistance, UV resistant irradiation, water tolerance, performance such as anti-oxidant all can be compared U.S. with natural basalt stone.(5) sound absorbing coefficient is higher.(6) excellent electric insulating and dielectric properties.(7) lower water absorbability.The water absorbability of CBF is lower than 0.1%, is lower than aramid fiber, rock wool and asbestos.(8) natural silicate intermiscibility.
Just because of basalt fibre the common concern that many premium propertiess can utilize, basalt fibre is subjected to material circle is at present arranged, but the output of basalt fibre can't improve the realization large-scale popularization fast.Mainly contain the reason of following several respects: (1) not all basalt all is fit to draw basalt fibre, basaltic composition fluctuation is big: because basalt is formed by earth lava, therefore cause it congenital defect, be exactly the fluctuation of its composition, not only the fluctuation of the composition in different mineral deposits is bigger, and chemical composition is put in same ore deposit also certain fluctuation range; Though distributing especially extensively, therefore tellurian basalt can be used in stable, efficient stringy basalt and few.Want to realize that by single a kind of basalt stable, efficient wire drawing difficulty is bigger, promptly enable to choose suitable basalt ore deposit also to allow expense great amount of manpower and financial resources and cause that raw material sources are narrow, raw material transportation and the cost rising of gathering; The material of single natural basalt raw material is short: show that by long-term experiment the crystallization ceiling temperature of composition of basalts and its wire-drawing shape temperature are very approaching, become fine temperature range narrow, and the recrystallization temperature of analysing in temperature gradient furnace test further shows basaltic recrystallization temperature point place, and its recrystallization temperature point has bigger discreteness.So just greatly reduce the basalt melt and become fine stability; phenomenons such as fracture of wire appear through regular meeting; thisly found, the inadequate basalt melt of homogenizing should not draw fiber with the bushing of high hole count; even and such basalt melt fiber do not find fracture of wire in pulling process, also can produce bigger fluctuation to the characteristic of aspects such as tensile strength of fiber.(2) the microlitic structure difference of basalt raw material inside: the difference of basaltic composition fluctuation and its suffered thermal history, also caused the difference of inner some crystallisate of basalt raw material, some crystallite thing (as quartz etc.) has higher melt, found in the process in that the basalt raw material is inadequate, these microcrystals fail fully to be melted and homogenizing, therefore in the basalt fibre moulding process, these found that inadequate microcrystal very easily becomes nucleus in drawing process and the appearance of quickening the crystallization phenomenon.Therefore be subjected to the restriction of present melting technology, the basalt raw material of high SiO2 content also is difficult to the raw material as suitable basalt fibre production.The physical and chemical performance of relevant natural basalt raw material and crystal phase structure thereof have comparatively in detail in U.S. Pat 3557575 to be introduced.(3) content of high ferriferous oxide in the basalt raw material: because contain rhombohedral iron ore (Fe2O3) and magnetite (Fe3O4) in the basalt, the diathermancy of basalt melt sharply descends, occur melt temperature inhomogeneous, found that efficient is low, wire drawing is easily breaked end, the bushing hole count also can't increase and finally cause output to reduce and the decline of quality; If the erosion to the platinum rhodium bushing is big and careless slightly on the other hand, iron ion will be reduced into metallic iron and cause bushing to poison, find by inquiry that the higher major part that accounts for of Chinese basalt ore iron level do not allocate most basalt ore deposit and be not suitable for producing basalt fibre.
Will the basalt fibre large-scale promotion to civil area, realize the extensive stably manufactured of basalt fibre, on the basis that does not influence product performance, improve the basalt raw material to be good technical measures, relevant at present document does not appear in the newspapers.
