Description
Technical field
The present invention relates to a kind of production formula of continuous glass fibre, relate in particular to a kind of glass fiber formula with good acid attack resistance, this fiber is applicable in the sour environment.
Background technology
Be used to make the most frequently used glass composition of continuous glass fibre precursor and be " E glass ".The liquidus temperature of E glass is 1050 ℃ or lower, and E glass is alkali metal oxide content less than 1% aluminium, boron, silicate glass.Because of containing higher boron content, structural framework is loose, is not sufficiently complete, and acid attack resistance is relatively poor, is very peeled off with resin matrix by acid attack easily under sour environment by the glass reinforced plastic of its preparation, loses intensity rapidly.
To this shortcoming, scientific research institution of many enterprises has carried out big quantity research.Spun glass like the said glass ingredient production of the patent of number of patent application 200710069773.5 compares the acid attack resistance that has improved glass greatly with the E glassy phase.But because it does not contain boron and fluorine etc. fully and fluxes, reduces capillary composition; Viscosity is very big under its high temperature; Be difficult to clarify, be easy to during wire-drawing shape to occur the fiber quality that defectives such as calculus, striped cause being produced at present technology condition poor; And product cost is high, is difficult to large-scale promotion application.
The present invention is directed to these characteristics of traditional E glass and existing acidproof erosion glass; Seek the factor that influences the glass acid resistance in the glass ingredient through a large amount of experiments; The adjustment prescription is sought best composition blend proportion, improving the acidproof rodent while, has guaranteed its good working performance.
Summary of the invention
For solving the shortcoming of traditional E glass acid resistance difference, the invention provides the glass formula that a kind of acid resistance is extremely superior, operation is more stable.
A kind of acidproof erosive spun glass is characterized in that: described spun glass each composition by weight percentage comprises that SiO2 56.5%; Al203 13.5%, and B203 0.8%, and CaO 23.0%; MgO 2.0%, and ZnO 1.2%, and F 0.4%; R20 (K20+Na20) 0.8%, TiO2 1.25%; It is to use silica powder, agalmatolite, unslaked lime, borocalcite, fluorite, zinc oxide, white titanium pigment, Natural manganese dioxide and soda ash, mixes the back fusion draw in weight part according to 68 parts silica powder, 688 parts agalmatolite, 240 parts of unslaked limes, 19 parts of borocalcites, 10 parts of fluorites, 22 parts Natural manganese dioxide, 17 parts of zinc oxide, 10 parts of white titanium pigments and 8 parts of soda ash and forms.
The fibre property of glass composition of the present invention comprises: fiberization temperature, liquidus temperature and Δ T.Fiberization temperature is defined as the temperature that viscosity is 1000 pools; Reduce fiberization temperature, increase operation annex work-ing life, be easy to produce, reduce production costs greatly.Liquidus temperature is defined as glass liquid state equilibrated top temperature between the matrix cystal phase with it, is easy to form crystal when being lower than this temperature, and fiberizing is interrupted.Another fibrosis performance is Δ T, is defined as the poor of fiberization temperature and liquidus temperature, and bigger Δ T helps fiberizing, has reduced the control requirement to process facility, reduces production costs.
The present invention partly is a kind of glass composition, and this glass composition is fit to make acidproof erosive continuous glass fibre.This glass composition is adapted at large tank furnace used middle production of existing E glass; Agalmatolite, living lime stone, borocalcite, silica powder, fluorite, Natural manganese dioxide and the soda ash etc. that use present E glass generally to adopt are main raw material, adopt the direct fusion method to process spun glass at an easy rate.

3Get 0.8%, F gets 0.4%, and introduces 1.25% TiO
2, TiO
2Can reduce the viscosity of glass when high temperature and play certain fluxing action, and also can improve the acid resistance of glass; For improving the acid resistance of glass, introduce 1.2% ZnO, ZnO is that glass forms midbody, in the glass forming process, with ZnO
4Form gets in the network structure, can improve the chemicalstability and the acidproof aggressiveness of glass; R
2O gets the electrical insulation capability of 0.8% assurance spun glass.
Prescription of the present invention has kept 0.8% B
2O
3, therefore 0.4% F has guaranteed temperature of fusion and the viscosity that glass is lower.In addition, with E glassy phase ratio, because B
2O
3, F reduces greatly, so its volatilization in kiln significantly reduces, alleviated environmental pollution.
Acid-resistant glass prescription of the present invention is characterized in that: this glass formula in 10% sulphuric acid soln, to set acid liquor temperature be digestion 4h, 24h, 48h, 96h respectively under 99 ℃ the condition, the weight residual rate is used K value representation, K
(96h)>=90%, and the weight residual rate of traditional E glass under similarity condition, K
(96h)Value is about 60%.
Among the present invention, glass is formed the reasons are as follows of being defined as above:
SiO

2O
3And B
2O
3Be both the composition that forms the glass skeleton, so SiO
2Be defined as at 56.5% o'clock, can provide enough skeleton structures to be unlikely to improve greatly the fusing difficulty again.
Al
2O
3Can effectively stop the glass phase-splitting at 13.5% o'clock, the stabilized glass skeleton structure is unlikely to improve greatly glass viscosity again well, guarantees transaction capabilities.
B
2O
3Not only guarantee glass excellent acid aggressiveness at 0.8% o'clock, also effectively reduced the temperature of fusion and the glass viscosity of glass.
CaO, MgO can reduce the viscosity of glass metal, are beneficial to glass melting, make the fibrosis difficulty but CaO, MgO and amount the crystallization noted phase separation phenomena can occur greater than 25% o'clock glass, and particularly MgO content was greater than 5% o'clock, and the crystallization noted phase separation phenomena can increase the weight of.Therefore CaO is defined as 23%, and MgO is defined as 2.0%.
