Description

A kind of glass fiber compound
(1) technical field
The present invention relates to a kind of glass fiber compound, relate in particular to the no boron with excellent mechanical properties and the glass fiber compound of essentially no magnesium.
(2) background technology
E glass is non-alkali glass, is to be used to produce the most frequently used glass ingredient of continuous glass fibre.Along with science and technology development, the performance of glass fibre reinforced composion has been proposed more and more higher requirement, thereby also required glass fibre to have the better properties performance.Because of containing the B of high level 2O 3, the structural framework of common E glass fibre is more loose, and mechanical property is relatively poor, has been difficult to satisfy the service requirements in fields such as wind power generation blade, high-performance glass steel conduit and automobile making.Simultaneously, high-load B 2O 3Also cause the traditional E glass fibre to have raw materials cost height, shortcoming such as big for environment pollution.
At present, generally contain the MgO of 1-5% in the E glass fiber formula of Cai Yonging, this component is mainly introduced by raw mineral materialss such as rhombspar, calcined dolomites.Consider that from the angle of raw materials cost and quality control most of enterprise adopts rhombspar.Facts have proved in a large number, the admixtion powder that contains rhombspar can cause serious dust from flying when dropping into the high temperature tank furnace, produced many-sided problem thus: first, dust from flying makes the interior sight line of kiln unclear, fusing in industrial television and the kiln, bubbling situation are observed and can't be reached the ideal effect, are unfavorable for the control of kiln melting technology; The second, dust from flying has aggravated the high temperature erosion to kiln refractory materials, metallic recuperator and flue; The 3rd, dust from flying has increased the deashing amount of flue, has improved the environmental improvement expense.In addition, though calcined dolomite can not produce and the rhombspar similar problem, because the activity degree of calcined dolomite is higher, the stably manufactured difficulty is big, the raw material storage difficulty, and parameters such as its composition, COD easily fluctuate, and produce unusually thereby cause easily.
(3) summary of the invention
Above-mentioned shortcoming at common E glass fibre, on the basis of common E glass, the present invention removes the boracic raw material of harm environment, cost costliness fully by the blend proportion of reasonable adjustment silicon oxide, aluminum oxide, calcium oxide, abandon rhombspar, calcined dolomite etc. simultaneously and contain magnesium raw material, to obtain to satisfy on the cost and the requirement on the environment and have excellent mechanical properties and draw the no boron of performance and the glass fiber compound of essentially no magnesium.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of glass fiber compound is characterized in that, contains following component, based on SiO 2, Al 2O 3, CaO, MgO, TiO 2, Fe 2O 3, Na 2O and K 2O, the weight percentage of each component is expressed as follows:
SiO 2 58.5～62％
Al 2O 3 13.5～16％
CaO 23～26％
MgO ＜0.3％
TiO 2 0.1～2％
Fe 2O 3 0.1～0.6％
R 2O＝K 2O+Na 2O 0.1～0.8％
The mold temperature of glass fiber compound of the present invention is 1240～1300 ℃, and liquidus temperature is generally low more than 50 ℃ than mold temperature.
SiO 2Be the main oxides that forms the glass skeleton, and work to stablize each component.The SiO that the present invention limited 2Content range is 58.5～62%, and in order to obtain the favorable mechanical performance, the present invention wishes to improve as far as possible SiO 2Content, but the too high meeting of its content makes too high fusing, the clarification difficulty of causing of glass viscosity.Preferred SiO 2Content range is 59～61%.
Al 2O 3Also be the oxide compound that forms the glass skeleton, with SiO 2In conjunction with the time can play substantial effect to the mechanical property of glass, and playing an important role aspect glass phase-splitting and the water resisting property stoping.The Al that the present invention limited 2O 3Content range is 13.5～16%, and in order to obtain the favorable mechanical performance, the present invention also wishes to improve as far as possible Al 2O 3Content, but the too high meeting of its content makes too high fusing, the clarification difficulty of causing of glass viscosity, and increase the danger of glass devitrification.Preferred Al 2O 3Content range is 14～15.5%.Simultaneously, limit SiO 2And Al 2O 3The content sum greater than 73%, can make glass obtain more outstanding mechanical property like this.
CaO is the network modifying oxide of glass, both can regulate glass viscosity, feed glass crystallization, also can improve chemical stability, the physical strength of glass, and frit is shortened, and improves the shaping speed of glass fibre.The CaO content range that the present invention limited is 23～26%, if the too low above-mentioned effect of its content is not remarkable; If the too high meeting of its content make frit too short-range missile cause the spun yarn difficult forming, and increase the danger of glass devitrification.Preferred CaO content range is 23.5～25%, more preferably greater than 24% and be not higher than 25%.
MgO has with CaO and similarly acts on, and mainly plays the effect of regulating glass viscosity, feed glass crystallization.Initiatively do not adopt rhombspar, calcined dolomite etc. to contain magnesium raw material among the present invention and introduce MgO, micro Mg O contained in the glass ingredient is all brought into the impurity form by other raw mineral materialss, and content range is less than 0.3%.
TiO 2The glass viscosity of introducing not only can reduce high temperature the time, also have certain fluxing action, but because a large amount of TiO 2It is inappropriate painted that glass is produced, so the introducing amount is unsuitable many.The TiO that the present invention limited 2Content range is 0.1～2%.
Fe 2O 3Introducing help founding of glass, also can improve the crystallization property of glass.But because iron ion and ferrous ion have pigmentation, so the introducing amount is unsuitable many.The Fe that the present invention limited 2O 3Content range is 0.1～0.6%.
Alkali-Metal Na 2O and K 2The introducing of O can reduce glass viscosity, improves the crystallization property of glass.But the introducing amount is unsuitable many, to avoid reducing glass intensity and chemical stability.The Na that the present invention limited 2O and K 2O total content scope is 0.1～0.8%.
On the basis of major scheme, each component of the present invention can further be followed following regulation: definition ratio C 1=(SiO 2+ Al 2O 3)/(CaO+MgO), the scope of ratio C 1 are 2.96～3.16.This ratio can be understood as the ratio of component total amount that forms glass network and the alkaline earth metal oxide component total amount of improving glass network, can be with it as the important parameter of regulating strength of glass and viscosity.
