Long-fiber glass has been used for various purposes in various industrial fields due to its high strength, insulation, non-flammability, dimensional stability and chemical resistance. Among them, alumina borosilicate-based long fiber glass is called "E-glass" And it is used as a reinforcing material for strength of plastics using building materials and electrical insulation characteristics because of its excellent electrical characteristics and weatherability.

Such an alumina borosilicate-based long fiber glass is RO-B 2 O 3 / Al 2 O 3 -SiO 2 (Where RO is an alkaline earth metal oxide), and when these components are contained in an appropriate composition, characteristics such as melting property, chemical durability, heat resistance, and insulation of the long-fiber glass can be imparted. Attempts have been made to provide the composition in a more economical manner.

Korean Patent No. 10-0917269 discloses a borosilicate-based long-fiber glass badge composition made of alkali-free glass of a thin film transistor liquid crystal display (TFT-LCD) glass substrate.

In addition, Korean Patent No. 10-1305447 discloses a wave glass produced in the production process of alkali-free alumina borosilicate based substrate glass used for an organic light emitting diode (OLED) display and a thin film transistor liquid crystal display (TFT-LCD) Discloses a badge composition of borosilicate roving fiberglass.

The wave glass used in the above patents is an alumina borosilicate glass which is alkali-free, that is, contains no or little alkali component, and has a composition of B 2 O 3 , Al 2 O 3 and SiO 2 , But it contains a considerable amount of borax, which is an additional expensive raw material, to supplement the deficient boron content and provide a certain level of alkali content.

Accordingly, there is a continuing need to develop a badge composition that can improve the performance of long fiber glass through more economical raw materials.

Korean Patent No. 10-0917269 Korean Patent No. 10-1305447

The present invention provides a badge composition capable of efficiently producing long-fiber glass by not only using a high-priced borax raw material but also imparting excellent meltability for producing long-fiber glass.

On the other hand, the present invention relates to a badge composition for the production of long-fiberglass which comprises, based on the total weight of the total components, 0.5 to 10% by weight of alkali-containing alumina borosilicate glass, 50 to 70% by weight of pyrophyllite, At least 2 to 30 wt%, and 10 to 18 wt% of faujasite.

In one embodiment of the present invention, the alkali-containing alumina borosilicate-based wave glass contains an alkali component in an amount of 5 to 15% by weight based on the total weight thereof.

In one embodiment of the invention, the badge composition may further comprise less than 2.5% by weight of borax and less than 0.3% by weight of gum, if necessary, based on the total weight of the total components.

In one embodiment of the present invention, the long fiber glass comprises 50 to 65% by weight of SiO 2 , 12 to 16% by weight of Al 2 O 3 , 0.1 to 10% by weight of B 2 O 3 , CaO 20 to 25% by weight, and MgO to 0.1 to 5% by weight.

In one embodiment of the present invention, the long fiber glass may contain less than 1.5% by weight R 2 O.

The badge composition for producing long-fiber glass of the present invention includes an alkali-containing alumina borosilicate-based glass to minimize the amount of expensive borax used in the production of long-fiber glass, exhibits excellent melting characteristics, It is possible to provide a composition suitable for glass.

Hereinafter, the present invention will be described in more detail.

A badge composition for making long-fiberglass according to an embodiment of the present invention includes alkali-containing alumina borosilicate-based glass, pyrophyllite, limestone or quicklime, and talc.

In one embodiment of the present invention, the alkali-containing alumina borosilicate-based wave glass is supplied with components of B 2 O 3 , Al 2 O 3 and SiO 2 necessary for glass formation, and an alkali component In an amount of 5 to 15% by weight, so that the melting temperature of the composition can be lowered during the production of the glass. Such an alkali-containing wave glass can be obtained, for example, in the production process of a cover glass for a touch sensor of an image display. The alkali component lowers the high melting temperature of SiO 2 , which is the main glass-forming oxide, and promotes dissolution, thereby reducing energy required for melting. On the other hand, when the alkali component is contained in an amount exceeding a certain amount, it is regarded as an impurity in the final long fiber glass, so that the content should not be out of the above range.

The alkali-containing alumina borosilicate-based wax glass may be contained in an amount of 0.5 to 10% by weight based on the total weight of the badge composition. When the content of the wave glass is less than 0.5% by weight, the amount of expensive borax used to supplement the boron component may increase. When the content of the wave glass exceeds 10% by weight, -It can deteriorate the electric insulation property which is the characteristic of the glass glass.

In one embodiment of the present invention, the pyrophyllite is a major source of SiO 2 and Al 2 O 3 which are glass forming oxides, in which pyrophosphate itself contains 70 to 80% of SiO 2 and 15 to 25% of Al 2 O 3 have. The badge composition of the present invention may contain such pyrophyllite in an amount of 50 to 70% by weight based on the total weight of the composition. When the content is less than 50% by weight, the content of SiO 2 or Al 2 O 3 becomes insufficient, If it exceeds 70% by weight, SiO 2 or Al 2 O 3 becomes excessively large, which is not preferable.

In one embodiment of the present invention, the limestone and quicklime are used to provide the CaO component of the glass to be produced, and the badge composition of the present invention contains at least one of limestone and quicklime in an amount of 2 to 30 wt% can do. When the content of at least one of the limestone and the quicklime is less than the above range, the content of CaO in the glass becomes insufficient. When the content exceeds the above range, CaO is excessively present in the glass.

In one embodiment of the present invention, the perovskite is a component used to supplement the B 2 O 3 component of the glass to be produced, and the perovskite is cheaper than borax which is a source of boron in the prior art, Can be lowered. The loop stone may be contained in an amount of 10 to 18% by weight based on the total weight of the badge composition. When the content is less than 10% by weight, the amount of expensive borax used to supplement the boron component may increase, Exceeds the above range, B 2 O 3 is excessively present in the glass, which is not preferable.

In one embodiment of the invention, the badge composition may further comprise less than 2.5% by weight of borax and less than 0.3% by weight of gypsum, if necessary, and if the content of borax exceeds 2.5% by weight, It is not preferable because it increases the manufacturing cost. In addition, Na 2 SO 4 serves as a refining agent in the melting process of the badge composition. In this process, gas is generated while decomposing in the melting process to grow fine bubbles, and bubbles Not only accelerates the defoaming process of the glass, but also helps to homogenize the glass. On the other hand, when the content of the gum is more than 0.3% by weight, the generation of sulfur oxides as an air pollutant can be increased.

The above-described badge composition for producing long-fiber glass of the present invention is meaningful in terms of resource utilization in that alkali-containing alumina borosilicate based glass which has been treated with waste or limited in its recycling has a meaning, It is possible not only to minimize the amount of expensive borax used, but also to exhibit excellent melting characteristics and to provide compositions suitable for long fiber glass. Thus, the badge composition according to the present invention can attain the improvement of the meltability of the long fiber glass and the effect of the substitution of the raw material for import by recycling the resources at the time of producing the long fiber glass.

That is, after melting the badge, the composition is cooled after homogenization to the molten glass, it is possible to prepare a long-fiber glass, such as alumina borosilicate long fiber glass, thus producing a long-fiber glass, SiO 2 50 to 65 wt. % Of Al 2 O 3, 12 to 16 wt% of Al 2 O 3 , 0.1 to 10 wt% of B 2 O 3 , 20 to 25 wt% of CaO and 0.1 to 5 wt% of MgO.

Among the components of the long fiber glass that can be produced using the badge composition according to the present invention, the SiO 2 is a network structural product oxide which forms a glass and can increase the chemical resistance of the glass. However, when the SiO 2 content is too high, the glass devitrification property may deteriorate. When the SiO 2 content is too low, the chemical resistance is decreased and the density is increased. Therefore, it is preferable that the content of SiO 2 be in the range of 50 to 65 wt%.

In addition, the Al 2 O 3 increases the high-temperature viscosity, chemical stability, thermal shock resistance and the like of the glass, and can contribute to increase the strain point and the Young's modulus. However, when the content of Al 2 O 3 is too high, the devitrification property and the chemical resistance may be lowered and the viscosity may be increased. When the content of Al 2 O 3 is too low, the elastic modulus may be lowered. Therefore, the content of Al 2 O 3 is preferably in the range of 12 to 16 wt%.

The above B 2 O 3 is a glass network structure product oxide which can improve the dissolution reactivity of the glass, improve the sealability, improve the chemical resistance, and contribute to lowering the density. However, when B 2 O 3 is contained too much, the acid resistance of the glass may deteriorate, the density may be increased, the strain point may be lowered and the heat resistance may be deteriorated. When B 2 O 3 is contained too low, And the resistance to such a phenomenon may be lowered. Therefore, the content of B 2 O 3 is preferably in the range of 0.1 to 10% by weight.

The CaO may contribute to lowering the density and improving the melting property. However, if the CaO content is too high, the density may be increased and the chemical resistance may be deteriorated. When the CaO content is too low, it is difficult to achieve the property improving effect due to the addition of CaO. Therefore, the content of CaO is preferably 20 to 25% by weight.

The MgO may contribute to lowering the density and improving the melting property similar to CaO, and the amount thereof may be 0.1 to 5% by weight.

On the other hand, the long-fiber glass may contain less than 1.5% by weight of R 2 O (alkali metal oxide).

R 2 O is a component regarded as an impurity of glass. If the content of R 2 O is 1.5% by weight or more, the electrical insulating property of the glass may be impaired. Accordingly, in the present invention, the content of R 2 O is controlled to a very small amount by suitably adjusting the composition of the badge composition for glass production as described above.

Hereinafter, the present invention will be described more specifically with reference to Examples, Comparative Examples and Experimental Examples. It should be apparent to those skilled in the art that these examples, comparative examples and experimental examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto.
