Abstract
The invention discloses a fluoride-free, boron-free and alkali-free glass fibre and a preparation method for the same. The fluoride-free, boron-free and alkali-free glass fibre is characterized by being prepared from following raw materials in parts by weight via melting and wire-drawing: 30-35 parts of quartzite sandstone, 10-13 parts of kaolin, 10-20 parts of pyrophyllite, 20-25 parts of lime, 5-10 parts of dolomite, and 8-20 parts of lithium-containing tailings, wherein the content of lithium oxide in the lithium-containing tailings is less than 5%; and fluoride and boron are completely not contained in the used raw materials. The fluoride-free, boron-free and alkali-free glass fibre has the ingredients in the following contents: 58-60% of SiO2, 22-25% of CaO, 2-3.5% of MgO, 13-15.0% of Al2O3, 0.3-0.45% of Fe2O3, 0.2-0.8% of R2O and 0.1-0.4% of Li2O3, wherein R2O is Na2O and K2O. Compared with the existing traditionally-applied E-glass fibres, fluoride-containing raw materials with the highest hazard, and volatile ingredients, namely, boron-containing raw materials are completely removed from the prescription of the glass fibre, industrial lithium-containing tailings are chosen preferably as one of the main raw materials, the melting temperature is lowered, and the emission of waste gases is greatly reduced. The fluoride-free, boron-free and alkali-free glass fibre can be directly produced in a large scale on a tank furnace with a pure oxygen combustion and electric boosting structure.
Description
Technical field
The present invention relates to a kind of production formula of alkali free glass fibre, be specifically related to few, environmentally friendly floride-free boron-free and alkali-free glass fiber of a kind of noxious gas emission and preparation method thereof.
Background technology
At present, traditional alkali free glass fibre formula all contains the F of 1% left and right of having an appointment
2With 6 ~ 8% boron oxide; When founding non-alkali glass due to F
2With SiO
2In conjunction with highly volatile, nearly fluorochemical more than 50% can vapor away with flue gas etc. in melting process, waste gas containing fluoride is processed need to expend a large amount of manpower and materials, off gas treatment causes heavy economical load to glass fiber industry, enter atmosphere and can cause serious consequence if deal with improperly, the harm common people's is healthy.Simultaneously boron compound is also a kind of composition of volatile costliness, enter atmosphere and can damage plant and human body equally if deal with its volatile matter improperly, and preparation cost is high, and the product glass fibre performance that makes is low.
Application number is that 200910231248.8 patent discloses a kind of Floride-free low-boron and alkaline-free glass fiber prescription and preparation method, although removed fluorine-containing raw material in this formula fully, but still contain easy volatile composition boron, can cause topsoil equally, and the product glass fibre performance that makes is low.
Summary of the invention
The object of the present invention is to provide a kind of floride-free boron-free and alkali-free glass fiber formula, on the basis of traditional E glass fiber formula, by adjusting the blend proportion of silicon, aluminium, calcium, magnesium, designed new environment-protective glass fibre formula, this formula is removed environmentally hazardous fluorochemicals and boron-containing compound fully, thereby it is few to reach noxious gas emission, and preparation cost is low, the purpose that product performance are high.
In order to reach the foregoing invention purpose, the technical solution used in the present invention is: a kind of floride-free boron-free and alkali-free glass fiber is provided, it is characterized in that, made through founding wire drawing by the raw material of following weight part:
30 ~ 35 parts of quartzite sandstones, 10 ~ 13 parts of kaolin, 10 ~ 20 parts of agalmatolites, 20 ~ 25 parts, lime, 5 ~ 10 parts of rhombspars and contain 8 ~ 20 parts of lithium mine tailings;
Fully not fluorine-containing in raw material and the boron of using;
The composition of described floride-free boron-free and alkali-free glass fiber and content thereof are:

Owing to removing the very capable fluorine-containing and boracic raw material of fluxing fully, the fusing clarification of glass becomes more difficult, and the process researchist is research and probe constantly, selects industry to contain the lithium mine tailing as raw material, has greatly improved fusing and the clarification of glass of the present invention; It is byproduct after industrial extracting metals lithium that industry contains the lithium mine tailing, in this mine tailing, the content of lithium in Lithium Oxide 98min less than 5%;
The preparation method of above-mentioned floride-free boron-free and alkali-free glass fiber is: with quartzite sandstone, kaolin, agalmatolite, lime, rhombspar with contain to add in agitator air after the lithium mine tailing measures by proportioning and mix, be transported in furnace hopper after mixing, send in tank furnace again and found, the glass metal of fusing is delivered to the platinum rhodium bushing after path, draw through drawing wire machine again, make the floride-free boron-free and alkali-free glass fiber of finished product.
In sum: floride-free boron-free and alkali-free glass fiber formula provided by the invention is compared the fluorine-containing raw material of having removed tool hazardness fully with the E glass fibre that present tradition is used, and removed easy volatile composition boracic raw material fully, and preferred a kind of industry contains the lithium mine tailing as one of main raw material, reduced glass melting temperature, significantly reduced exhaust gas emission, can be on the tank furnace of pure oxygen burning and electricity fusing-aid structure directly scale operation; And the present invention contains the lithium mine tailing by being added with the industry that benefits fusing and clarification, makes this glass fibre have similar processability to the E glass fibre, and the glass fiber product performance of producing is all higher than existing E glass fiber product performance.
