Background technology
The most frequently used glass composition that is used to make the continuous glass fibre precursor is a non-alkali glass, strengthens the matrix material that resin can obtain excellent property with its.But expansion day by day along with the alkali free glass fibre Application Areas; With regard to the present mechanical property of alkali free glass fibre; It can not satisfy the requirement of light-duty military weapon, aerospace parts, special purpose trolley part and field of wind power generation far away, all need seek to be fit to have more HS, erosion resistance and the light matrix material of high thermal resistance good quality.
Can make this matrix material satisfy the requirements at the higher level in these fields through improving fortifying fibre.
To above situation, scientific research institution of many enterprises has carried out big quantity research, to improve spun glass mechanics mechanical property by every means.Like USP 3402055, its tensile strength is significantly increased than alkali free glass fibre, but its liquidus temperature is up to more than 1471 ℃; The bushing temperature is up to 1571 ℃; The production difficulty is very big, has increased the erosion of glass metal to the kiln refractory materials, has shortened the life-span of platinum bushing; Improved its production cost greatly, therefore be difficult to apply.Like Chinese patent 94111349.3; In order to improve the crystallization property of glass; More a large amount of introducings Fe2O3, influence the melting properties of glass metal but Fe2O3 introduces the excessive diathermancy that can reduce glass metal, and obviously make spun glass painted; Too much Fe2O3 also is prone to be reduced to fe by molybdenum electrode, causes the platinum bushing to produce intoxication accident.
In view of above situation,, electronics military for satisfying and industry needs such as civilian the invention describes and a kind ofly both can increase substantially the mechanics mechanical property than alkali free glass fibre, and have the reinforcing glass fiber than high performance-price ratio.
Summary of the invention
The objective of the invention is to problem to above-mentioned existence; A kind of composition high strength glass fiber composition reasonable in design is proposed; Reduce the fiberization temperature of spun glass, reduce task difficulty, improve tensile strength, temperature tolerance, erosion resistance and the acid resistance of spun glass simultaneously.High strength glass fiber composition according to the invention contains Fe through introducing
2O
3Lower calcined oxide aluminium substitution agalmatolite reduces impurity and introduces the purity that has guaranteed to change glass ingredient, has kept the mechanical strength of said composition most possibly, has also improved the diathermancy of glass metal simultaneously, cuts down the consumption of energy stably manufactured.The present invention introduces about 6-12% through using an amount of blast furnace slag according to concrete needs, reaches to reduce fusing difficulty and the purpose that reduces energy consumption.
This glass formula makes it be in the high-temperature stable compositing area through the blend proportion of adjusting silicon, aluminium, magnesium on the basis of traditional silicon, aluminium, magnesium TERNARY GLASS, and has guaranteed the mechanics mechanical property of final fiber through adjustment three ratio.
Compsn of the present invention comprises: 56-65wt%SiO

2O
3, 11.5-23wt%RO (RO is CaO, MgO, SrO and BaO sum), the alkalimetal oxide of 0-2.5%; Greater than 0.15% less than 1.0% CeO2;
In order effectively to improve tensile strength of fiber, acid resistance, temperature tolerance and the erosion resistance of spun glass, improve the melting properties of admixtion, improve the devitrification behavior of glass, in the whole glass ingredient with SiO
2Get about 56-65wt% Al
2O
3Get 18.5-25.8wt%, sum of the two is not less than 78wt%.Fiberization temperature and the high-temperature viscosity of while in order to reduce spun glass, in the work-ing life of prolongation platinum bushing, the MgO content that the present invention is fit to is 7-16wt%.
The glass melting temperature of above-mentioned SiO2-Al2O3-MgO system is high; Clarify relatively poor and wire-drawing operation is difficult; To the characteristics of this glass composition, adopt fluorite and boron cpd as fusing assistant in the traditional glass fiber, but the equal highly volatile of fluorine wherein and boron is very harmful to atmosphere.Not fluorine-containing fully in the present invention and boron, thus destruction reduced to the bulk glass bond structure.
To the characteristics of this glass composition, it is single to introduce chemical ingredients in the glass composition of the present invention, and the Calcined polishing aluminum oxide that Fe2O3 content is lower replaces a certain amount of agalmatolite; Both reduced the applying pressure of pyrophyllite deposit; Can reduce the unnecessary impurity in the glass again, improve the diathermancy of glass metal, effectively reduce the fiberization temperature of glass metal; Reduced the applying pressure of path temperature and kiln; And obviously improved the color of spun glass, alleviated corrosion, prolonged the work-ing life of bushing the platinum bushing.
Calcined polishing aluminum oxide is with bauxite (Al

2O) pulverize the back with high temperature hydrogen sodium hydroxide solution dipping, obtain sodium aluminate solution; Cross and filter to remove residue, the cooling and add aluminum hydroxide crystals of will filtrating, through stirring for a long time, sodium aluminate solution can divide and parses aluminum hydroxide precipitation; Precipitate and separate is come out to clean,, just obtain alpha-alumina powder (mother liquor reusable edible) again at 950-1200 ℃ temperature lower calcination.
Clear up problems in order further to improve glass metal, the CeO2 less than 1% mixes use with process incinerating blast furnace slag greater than 0.15% in interpolation, reaches good clarifying effect.The CeO2 addition did not have obvious effects less than 0.15% o'clock, and usage quantity is greater than after 1%, and not only cost obviously raises but also clarifying effect not have the further trend of growth.Cerium oxide is the oxide compound that appraises at the current rate, and the cerium dioxide pyrolytic decomposition goes out oxygen, and 1 degree centigrade of ability of the every rising of temperature isolated oxygen from its Chemical bond key is many more, and clarification is big more.And the solubility with temperature of oxygen raises and reduces, thus the generation clarification.Prescription according to the invention needs higher glass melting temperature, and cerium oxide is the finings that suits.In reaction, emit simultaneously the oxygen of nascent state, also can be with iron (Fe at a low price
2+) be oxidized to red oxide of iron, further reduce glass coloring, because trivalent Fe
3+Tinting strength only be equivalent to Fe
2+1/10, so in use, can increase the usage quantity of blast furnace slag.Cerium oxide has also played the effect of glass chemistry discoloring agent in this prescription, cerium oxide has higher oxidation potential, thus better than traditional finings, have splendid combining with using simultaneously through the incinerating blast furnace slag.
Because oxygen is emitted in the valence state change under the CeO2 high temperature, can play clarifying effect by stirred glass liquid on the one hand, oxidizing atmosphere can make its reductibility of the better balance of blast furnace slag on the other hand.
Because the more common alkali free glass fibre of this glass formula clarification processing temperature rises about 140 ℃, in order to solve fusing and to clear up problems, at first electricity fusing-aid shared energy distribution ratio in whole fusing has been adjusted in design; Common E glass can not have steady and continuous production on the kiln of electricity fusing-aid.And the production of this glass formula, electricity fusing-aid becomes requisite assembly.Electricity fusing-aid is to adopt electrode directly to insert the mode of glass metal heating, and capacity usage ratio is high, and near the temperature of glass liquid the electrode can have good effect to forcing the glass metal fusing up to more than 1700 ℃.Increase melting area and the electricity fusing-aid power of settling section and the job stabilization that energy input can improve this glass formula effectively.Electricity fusing-aid energy input ratio is crossed to hang down and can be caused glass melting slow, is easy to generate during wire drawing and does not melt raw material calculus completely, makes the flow operation at full capacity of wire-drawing operation, can not satisfy the quantity-produced requirement; The too high meeting of electricity fusing-aid energy input ratio causes temperature of glass liquid wayward and all temperature of glass liquid is not too high; Quicken the erosion of kiln refractory materials; And can produce more blub; Found simulation and the actual adjustment of kiln through laboratory repeatedly, finally confirmed electricity fusing-aid energy input ratio between 20%-35% according to the thawing settling time of this prescription admixtion, the input of the energy consumption of melting area accounts for the whole 60-85% that founds the kiln energy input and can obtain fine melting rate and clarifying glass.Electricity fusing-aid power input melting area accounts for the 40-60% of total electricity fusing-aid power, settling section 30-35%, and melting area and settling section electricity fusing-aid power summation are no less than 72%; The electricity fusing-aid electric current is not higher than 420A, and voltage is not higher than 120V, the cooling of electrodes use water cycle, and the watercooling jacket temperature can not be above 800 ℃. can produce direct wire-drawing shape on the suitable platinum rhodium bushing of E glass after this glass composition fusing homogenizing.
The fibrosis performance of glass composition of the present invention comprises: fiberization temperature, liquidus temperature and △ T.Fiberization temperature is defined as the temperature that viscosity is 1000 pools; Reduce fiberization temperature, can increase operation annex work-ing life, be easy to produce, reduce production costs greatly.Liquidus temperature is defined as glass liquid state equilibrated top temperature between the matrix cystal phase with it, is easy to form crystal when being lower than this temperature, and fiberizing is interrupted.Another fibrosis performance is △ T, is defined as the poor of fiberization temperature and liquidus temperature, and bigger △ T helps fiberizing, has reduced the control requirement to process facility, is easy to control and reduces production costs.
The admixtion of glass of the present invention preferably comprises above institute determinant and processes fiber and have and be lower than about 1300 ℃ fiberization temperature and at least about 70 ℃ △ T.The fiber of this glass composition preparation has above the tensile strength of fiber of alkali free glass fibre more than 20%.
This glass ingredient is owing to remove the very capable fluorine-containing mineral of fluxing fully; The fusing clarification of glass becomes difficult; Use the lower Calcined polishing aluminum oxide of Fe2O3 content as a kind of main raw material through a large amount of experimental exploring and parameter simulation, can effectively improve the melting capacity of glass metal.Add CeO2 and in design, considered clearing up problems of high-viscosity glass liquid.The CeO2 addition did not have obvious effects less than 0.15% o'clock, and CeO2 is higher than at 1% o'clock, and effect is little, and the color of glass is also had certain influence.Steel-making sub product-the blast furnace slag that meanwhile has greater activity has also improved the fusing and the clarification of this glass greatly as a kind of main raw material.
Among the present invention; Except that mentioned component; Introduce total amount compositions such as 2% TiO2, SrO, ZnO, Fe2O3, P2O5, MnO2, ZrO2, Cr2O3, Y2O3 at the most; The introducing of these compositions is played improvement effect energetically to the glass high-temperature stability, has also further improved the tensile strength of spun glass.
The present invention also comprises a kind of matrix material, and this matrix material strengthens base material with above-mentioned spun glass as ideal exactly.This matrix material is applicable in the application of and low weight higher in the strength and stiffness requirement and uses, comprises defence and military, electronic application, civilian industry and other association areas.
