Problems solved by technology

[0005] However, there are very few studies on improving the flame retardant properties of glass fiber reinforced composites directly by improving the flame retardant properties of glass fibers.
In the market and related reports, there is no glass fiber with low melting point, flame retardant effect, which can be used to reinforce resin-based materials

preparation example Construction

[0049] The preparation method of the glass fiber is not particularly limited in the present invention, and it can be prepared according to the tank kiln method well known to those skilled in the art.

[0050] According to the actual formula of the glass, calculate the required raw material addition ratio; according to the ratio, the various raw materials are quantitatively transported to the mixing bin, fully mixed evenly, and qualified batch materials are obtained; the batch materials are transported to the kiln head bin of the pool kiln, and The feeder is delivered to the pool kiln at a uniform speed; the batch material is heated, melted, clarified and homogenized in the pool kiln at a high temperature of 1100-1400°C to form qualified molten glass; the molten glass is cooled to the forming temperature through the working channel, and then passed through the platinum The bushing plate flows out to form glass filaments; the glass filaments are quickly drawn into glass fibers wi...

[0057] The glass fiber is prepared by the pool kiln method.

[0058] According to this ratio, the various raw materials are quantitatively transported to the mixing bin, fully mixed evenly, and qualified batch materials are obtained;

[0059] Convey the batch material to the kiln head silo of the tank kiln, and deliver it to the tank kiln at a uniform speed by the feeder;

[0060] The batch material is heated, melted, clarified and homogenized at a high temperature of 1400 ℃ in the tank kiln to form qualified glass liquid; the glass liquid is cooled to the forming temperature through the working channel, and then flows out through the platinum drain plate to form glass filaments;

[0061] The glass filaments are quickly drawn into glass fibers with a set diameter under the high-speed traction of the wire drawing machine. After being sprayed and cooled, coated with a sizing agent and bundled, they are wound into a silk cake by the wire drawing machine; in the programmed automat...

Abstract

The invention provides a glass fiber. The glass fiber comprises 42-48wt% of SiO2, 2-8wt% of Al2O3, 15-25wt% of B2O3, 3-8wt% of CaO, 1-4wt% of MgO, 0.5-3wt% of TiO2, 8-15wt% of ZnO, 5-12wt% of Na2O, 1-5wt% of Li2O, and 1-30wt% of B2O3 and Na2O. The softening point of the glass fiber containing the components is not higher than 600 DEG C, the melting temperature is low, and the glass fiber can be quickly softened and melted at a high temperature. When the glass fiber is used for the glass fiber composite material, the glass fiber is quickly melted at a high temperature, a candlewick effect is avoided, and the combustion of organic materials is restrained, so that the glass fiber composite material has the flame-retardant effect. In addition, the glass fiber is small in preparation difficulty, low in production cost, good in mechanical property and good in stability, and the glass fiber can satisfy the requirements for the strength and the service life of the glass fiber composite material.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic materials, in particular to a glass fiber and a glass fiber composite material. Background technique [0002] Glass fiber is a high-performance inorganic material with excellent mechanical properties, corrosion resistance, high temperature resistance and good insulation. It is a glass fiber composite material formed by compounding organic materials such as thermosetting resins or thermoplastic resins, and is widely used in various fields of the national economy. Glass fiber composite material is one of the fastest-growing and most widely used high-performance composite materials. [0003] Since glass fiber composite materials can contain various organic materials, the disadvantage of organic materials is that they are flammable and easy to cause fires. When a fire occurs, the organic material part of the glass fiber composite material will melt, burn, and decompose under the action of high ...
