Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the variation chart with the increase fiber tensile strength of cesium silicate content；Fig. 2 is the glass for being added to SrF2 ingredient
The micro- enlarged drawing of glass fibre when the content of glass fiber and SrF2 are 2.8~3.0 wt%；Fig. 3 be not added with SrF2 at
The micro- enlarged drawing of glass fibre or SrF2 addition non-2.8~3.0 wt% glass fibre of content divided.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
- Fig. 3 referring to Fig.1, the composite fibre is mutually mixed with on-line continuous glass fibre by offline terylene and is formed, described
On the basis of its total weight by constituent of glass fibre, content in component containing SiO2 be 55.0~59.0 wt%,
The content of Al2O3 is that the content that the content of 19.0~23.0 wt%, MgO is 2~3.8 wt%, CaO is 14.0
The content of~16.0 wt%, SrF2 are 2.8~3.0 wt%, and SiO2, Al2O3, MgO, SrF2 and CaO's is total
Content is the composition of 99.5 wt% or more, and the glass fibre is to draw online, and the terylene is finished silk, multi beam difference into
The terylene of yarn angle is drawn converges slabbing after tension adjustment, the terylene tow after convergence after separation with infiltrated
The processed glass fibre of agent carries out compound.
The present invention increases unique SrF2 ingredient on the basis of traditional fiberglass component is constituted, we are by anti-
Retrial is tested, and the tensile strength of glass fibre itself can not be significantly improved when SrF2 ingredient is excessive and very few, in glass
In the identical situation of fibre fractionation SiO2, Al2O3, MgO, CaO, we gradually pass SrF2 ingredient by lower 1%
Increase to before 2.8%, the tensile strength of glass fibre fluctuates within normal range (NR), have no and significantly improve, and when SrF2 at
When point increasing to 2.8%, significantly rising to occurs in the tensile strength of glass fibre, we will mix the fiber and not of SrF2 ingredient
The fibre section for mixing SrF2 ingredient has carried out micro- amplification discovery, is added to the glass fibre of SrF2 ingredient as shown in Figures 2 and 3
And the content of SrF2 is different compared to the glass fibre that is not added with SrF2 ingredient and SrF2 content when being 2.8~3.0 wt%
Glass fibre, structure is even closer, and the gap of appearance significantly reduces, and is commonly not added with the tension of the glass fibre of SrF2 ingredient
Intensity is stretched generally between 37 ~ 43KMpa, and the component that we use, intensity is stirred near 43KMpa, and adds SrF2 ingredient
Glass fibre and SrF2 content be 2.8~3.0 wt% when, rising to occurs in the tensile strength of glass fibre, and reaches
53 ~ 58.3KMpa, peak value is reached when the content of SrF2 is 2.9 wt% is 58.3KMpa.Use glass fibre of the present invention
Glass fibre made of component, intensity improves 30% or more, in molecules experimentation, hence it is evident that reduce glass fibre and fracture
Probability, improve experiment success rate, reduce experimental cost, reduce experimental period.
The glass fibre its in constituent also containing the TiF4 of 0.2~0.3wt%.
We have found by further experiment, and after the TiF4 that 0.2~0.3wt% is added, addition is added to SrF2 ingredient
Glass fibre and SrF2 content be 2.8~3.0 wt% when, so that the tensile strength of glass fibre is more easily reachd height
Numerical value, it is easier to enter within the scope of 56.8 ~ 58.3KMpa.Further depth analysis, one side Ti ingredient is to the strong of glass fibre
Degree makes moderate progress, and the addition of another aspect TiF4 increases the content of F element in glass fibre, so as to supplement glass fibre
The F element of evaporating loss when raw material melts.Glass fibre is set to more easily reach high intensity.
The glass fibre its in constituent also containing the ZnMoO4 of 0.1~0.15wt%.
We by it has furthermore been found that be added be added to SrF2 ingredient glass fibre and SrF2 content be 2.8~
When 3.0 wt%, while increasing glass fibre finished product made of the ZnMoO4 of 0.1~0.2wt% compared to common glass fibers
For dimension at 700~800 degrees Celsius, tensile resistance has obtained certain raising, takes the photograph compared to simple glass fiber, 700~800
Tensile strength improves 1.1~1.7% or so when family name spends, and glass fibre is made to have preferable high temperature resistance.
Glass fibre its in constituent also containing the Na2S2 of 0.01~0.5wt%.
We have found after further research, are in the content that the glass fibre and SrF2 that are added to SrF2 ingredient is added
When 2.8~3.0 wt%, while increasing glass finished-product made of the Na2S2 of 0.01~0.5wt% compared to being not added with SeS2
Glass finished-product peak value is increased to 58.93KMpa, Na2S2 in conjunction with SrF2 after make glass fiber strength peak value is made and be improved,
This point research further improved for glass fiber strength is extremely important, and Na2S2 there is no to improve fibre strength at present
Existing literature record.
It by glass fibre raw material in platinum material crucible, at 1400 DEG C~1500 DEG C, melts, melts while stirring
System 8 hours, the glass melted is put into fiber drawing furnace, remelted at 1430~1450 DEG C, melten glass passes through platinum
Leting slip a remark for golden bushing is drawn into diameter as 5~13 μm of continuous fibers, is directly immersed in 0 DEG C from the glass fibre for output of leting slip a remark
In mixture of ice and water, finished product is obtained.
As shown in table 1, we provide part as strontium fluoride (SrF2) glass fibre is adulterated in the raising of fluorination content of strontium
The value of tensile strength (KMPa), when 43KMpa near stir during 0 ~ 2.8 by fiber tensile strength for SrF2 content,
And when SrF2 content increases to 2.8 or more, fiber tensile strength rises to suddenly, and peak value 58.3 has been reached between 2.8 ~ 3,
It further increases, is back to 43KMpa and nearby stirs.
Table 1 adulterates strontium fluoride (SrF2) glass fibre tensile strength (KMPa) table with the raising of fluorination content of strontium
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention, although
Present invention has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, still can be right
Technical solution documented by foregoing embodiments is modified or equivalent replacement of some of the technical features.It is all
