Description
Technical field
The present invention relates to the factory formula of a kind 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 about about 1%2With 6 ~ 8% boron oxide; When founding alkali-free glass due to F2With SiO2In conjunction with highly volatile, the fluoride of nearly more than 50% can vapor away with flue gas etc. in fusion process, waste gas containing fluoride processes to be needed to expend substantial amounts of manpower and materials, exhaust-gas treatment causes heavy financial burden to glass fiber industry, entering air can cause serious consequence if dealing with improperly, the harm common people's is healthy. Simultaneously boron compound is also the composition of a kind of volatile costliness, enters air can plant and human body be damaged equally if dealing with its volatile matter improperly, and preparation cost is high, and the product glass fibre performance prepared is low.
Application number be the patent disclosure of 200910231248.8 a kind of Floride-free low-boron and alkaline-free glass fiber prescription and preparation method, although this formula completely eliminated fluorine-containing raw material, but still contain effumability composition boron, atmospheric pollution can be caused equally, and the product glass fibre performance prepared is low.
Summary of the invention
It is an object of the invention to provide a kind of floride-free boron-free and alkali-free glass fiber formula, it is on the basis of traditional E glass fiber formula, by adjusting the blend proportion of silicon, aluminum, calcium, magnesium, devise new environment-protective glass fibre formula, this formula removes environmentally hazardous fluorochemical and boron-containing compound completely, thus it is few to reach noxious gas emission, preparation cost is low, the purpose that properties of product are high.
In order to reach foregoing invention purpose, the technical solution used in the present invention is: provide a kind of floride-free boron-free and alkali-free glass fiber, it is characterised in that prepared through founding wire drawing by the raw material of following weight portion:
Quartzite sandstone 30 ~ 35 parts, Kaolin 10 ~ 13 parts, pyrophillite 10 ~ 20 parts, 20 ~ 25 parts of Calx, dolomite 5 ~ 10 parts and containing lithium mine tailing 8 ~ 20 parts;
Used raw material is entirely free of fluorine and boron;
Composition and the content thereof of described floride-free boron-free and alkali-free glass fiber is:
SiO258~60%��CaO22~25%��MgO2~3.5%��Al2O313~15.0%��Fe2O30.3~0.45%��R2O0.2 ~ 0.8% and Li2O0.1 ~ 0.4%; Wherein, R2O is Na2O and K2O��
Fluorine-containing and the boracic raw material very strong owing to removing fluxing capabilities completely, the fusing clarification of glass becomes more difficult, through research worker constantly research and probe, selects industry containing lithium mine tailing as raw material, substantially improves fusing and the clarification of glass of the present invention; Industry the mine tailing containing lithium be the side-product after industrial extracting metals lithium, in this mine tailing, the content of lithium in lithium oxide less than 5%;
The preparation method of above-mentioned floride-free boron-free and alkali-free glass fiber is: adds in air agitator after quartzite sandstone, Kaolin, pyrophillite, Calx, dolomite and the mine tailing containing lithium being measured by proportioning and mixes, it is transported to after mix homogeneously in furnace hopper, it is re-fed in tank furnace to found, platinum-rhodium alloy bushing delivered to by the vitreous humour of fusing after path, draw then through wire drawing machine, prepare finished product free-floride boron-free and alkali-free glass fiber.
In sum: floride-free boron-free and alkali-free glass fiber formula provided by the invention completely eliminated the fluorine-containing raw material of most hazardness compared with the E glass fibre of tradition application at present, and eliminate effumability composition boracic raw material completely, and preferred a kind of industry mine tailing containing lithium is as one of primary raw material, reduce glass melting temperature, drastically reduce the area toxic emission, it is possible to direct large-scale production on the tank furnace of pure oxygen burning and electric boosting structure; And the present invention is by being added with the industry benefiting fusing and clarification containing lithium mine tailing, makes this glass fibre have similar processability to E glass fibre, and the glass fiber product performance produced is above existing E glass fiber product performance.
