Description
Technical field
The present invention relates to technical field of inorganic nonmetallic materials, more particularly to a kind of glass fiber compound and glass fibers
Dimension.
Background technology
Glass fibre belongs to inorganic non-metallic material, and it has, and high mechanical strength, electrical insulating property are good, heat resistance is strong, physics
Many advantages, such as chemical property is stable, is widely used in Aero-Space, automobile, ship, petrochemical industry, the energy, electric power, building etc. many
Field, is the maximum inorfil reinforcing material of current application amount.In the application process of glass fibre, with composite system
Product sizes is continuously increased, and people propose higher and higher require to the mechanical property especially modulus of elasticity of glass fibre.
For lifting glass fiber strength and the method for modulus, at present existing many correlative studys.Most typical is exactly S
Glass and R glass.S glass basic composition is：65wt% SiO2, 25wt% Al2O3, 10wt% MgO.S glass fibres
Theoretical filament strength is up to 4500MPa, and modulus of elasticity is more than 85GPa, and mechanical property is very excellent.But its forming temperature exceedes
1470 DEG C, and easily crystallization, production difficulty is very big, it is impossible to realize large-scale promotion application.R glass is also that a kind of high intensity is done
Modulus glass fiber, it is usually by SiO2、Al2O3, CaO, MgO composition, be generally considered to be production difficulty and mechanical property
One kind is compromise, so that compared with S glass, with more producing feasibility.
Japan Patent JP8231240 discloses a kind of glass fiber compound, and it contains 62~67wt% SiO2, 22~
27wt% Al2O3, 7~15wt% MgO, 0.1~1.1wt% CaO, 0.1~1.1wt% B2O3.The glass fibre leads to
Cross and add a small amount of CaO and B2O3So that number of bubbles is obviously improved with respect to S glass fibres, but shaping is still extremely difficult, into
Type temperature is more than 1460 DEG C.
Japan Patent JP2003171143 also illustrates a kind of high-strength high-modulus glass fiber, and it contains 55~65wt%
SiO2, 17~23wt% Al2O3, 7~15wt% MgO, 2~6wt% CaO, 1~7wt% TiO2.Compared with S glass
Glass, although the glass fibre mechanical property has been sacrificed, processability, which has, to be obviously improved, forming temperature is about 1340~
1380℃.But TiO in the glass2Content is very high so that glass colour is partially deep, which has limited its some fields application.
A kind of high-performance glass fiber composition of Publication No. US2010/0160139 U.S. Patent Publication, including：
64~75wt% SiO2, 16~24wt% Al2O3, 8~12wt% MgO, 0.25~3wt% Li2O+Na2O.Relative to
S glasses, this glass fibre adds a certain amount of Li2O and Na2O, thus reduce the high temperature viscosity and shaping difficulty of glass.
But, if Li in the system glass2O and Na2O additions are relatively low, then act on unobvious；Addition is too high, then has a strong impact on glass
The insulating properties and decay resistance of glass fiber, therefore the fibre-forming performance of glass fibre is still difficult to control to.
Application No. CN201080070857.0 patent discloses a kind of high strength glass fiber, and its composition is included：
56~61wt% SiO2, 16~23wt% Al2O3, 8~12wt% MgO, 6~10wt% CaO, 0~2wt%'s
Na2O, the Li less than 1wt%2O, and the transition metal oxide less than 2wt%.The glass fibre obtains good really
Mechanical performance, but can be seen from its practical embodiments, in order to balance its production difficulty, it adds the Na more than 1%2O, and
Too high Na2O can have an impact to the chemical stability of glass fibre.
Application No. CN201180028428.1 patent also discloses that a kind of high strength glass fiber, its composition bag
Contain：57~63wt% SiO2, 19~23wt% Al2O3, 10~15wt% MgO, 4~11wt% CaO, and SiO2、
Al2O3, CaO, MgO total total content be more than 99.5wt%.Glass fibre modulus of elasticity is up to more than 96GPa in the patent,
But simultaneously because it requires to control very low Fe2O3And alkali metal oxide content, not only cost of material is high, devitrification problem and molten
All there is certain solution difficulty in change problem.
The content of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of glass fiber compound and glass fibers
Dimension, while having excellent mechanical property and the processability compared with low viscosity.
The invention provides a kind of glass fiber compound, including following component：
Said components amount to 100%.
Silica (SiO2) it is to form one of main oxides of glass network, it, which mainly rises, improves the mechanical strong of glass
The effect of degree, chemical stability and heat endurance, but too high levels can increase the viscosity and fusion temperature of glass, cause glass fibers
Dimension shaping difficulty and production cost are higher.SiO of the present invention2Content be 50.0wt%~56.0wt%, preferably 52.4wt%~
55.8wt%.
Aluminum oxide (Al2O3) be also to form one of main oxides of glass network, it have reduction devitrification of glass tendency,
Chemical durability of glass, the effect of mechanical strength are improved, if but Al2O3Too high levels, can cause glass viscosity excessive, glass again
Into fine difficult, it is also easy to devitrification problem occur.Al of the present invention2O3Content be 18.0~24.0wt%, preferably 19.0wt%~
23.6wt%.
The Al2O3、SiO2Total content and mass fraction ratio are significant to alumina silicate glass modulus of elasticity,
Al2O3Relative scale is higher, and glass modulus is big, but production difficulty and tendency towards devitrification can also be dramatically increased simultaneously, present invention limit
Determine SiO2With Al2O3Total content be 72.5wt%~79.5wt%, it is preferred that the SiO2With Al2O3Total content be
74.2wt%~78.8wt%.Al2O3/SiO2Mass fraction ratio is 0.32~0.45, preferably 0.34~0.44.The ratio
Scope ensure that glass fibre has optimal modulus of elasticity and melt drawing performance, recrystallization temperature.
Calcium oxide (CaO) and magnesia (MgO) belong to glass structure network modifying oxide, with reduction glass high temperature
Viscosity, the effect for improving devitrification of glass tendency.Wherein MgO ionic radius are less than CaO, thus higher MgO ratios, contribute to shape
Into finer and close glass network structure, glass modulus is lifted.But if content of MgO is too high, production difficulty can become to be difficult to
Receive.CaO content of the present invention is 8.0wt%~10.0wt%, more preferably 9.0wt%~9.7wt%, and content of MgO is
9.0wt%~12.0wt%, more preferably 10.0wt%~11.8wt%.CaO and MgO total content be 18.2wt%~

MgO/CaO mass fractions ratio is 1.10~1.44.
In the present invention, titanium dioxide (TiO2) addition help to improve glass temperature flowing and tendency towards devitrification, improve
Fiberglass machine performance and decay resistance.But otherwise the content of titanium dioxide can influence glass face no more than 1.5wt%
Color.TiO of the present invention2Content be 0.2wt%~1.5wt%, more preferably preferably 0.5wt%~1.0wt%, 0.2wt%
~0.8wt%.
A small amount of Fe contained therein2O3Be conducive to tank furnace heat transfer, but if too high levels, to the face of glass fibre
Color and heat transfer property are all adversely affected.Iron oxide content of the present invention is defined to 0.1wt%~0.6wt%, preferably 0.2wt%
~0.5wt%.
Li2O is the special composition of the comparison of the invention added, and it has good fluxing effect in silicate glass,
Reduction glass high temperature viscosity that can be obvious, while its ionic radius is small, electric-field intensity big, to improving glass springform
Amount, reduction glass density have positive role.In order to effectively play Li2Li in O positive effects, the present invention2O content is defined to
1.0wt%~3.0wt%, more preferably 1.05wt%~2.0wt%.
The a small amount of Na added2O and K2O improves devitrification of glass tendency helpful to reduction glass viscosity.But in glass
Overall alkali metal content also can not be too high, otherwise can damage the chemical stability of glass.Therefore glass composition Na of the present invention2O and
K2O total contents are 0.1wt%~0.8wt%, more preferably 0.1wt%~0.6wt%.
