preparation example Construction

[0054] 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.

[0055] The tank kiln method is as follows: calculate the required raw material addition ratio according to the actual glass formula; transport various raw materials quantitatively to the mixing bin according to the ratio, and mix them thoroughly to obtain qualified batch materials; transfer the batch materials to the tank. The kiln head hopper of the kiln is delivered to the pool kiln at a uniform speed by the feeder; the batch material is heated, melted, clarified and homogenized in the pool kiln at a high temperature of 1300-1500°C to form qualified molten glass; the molten glass passes through the working channel Cool to the molding temperature, and then flow out through the platinum bushing to form glass filaments; the glass filaments are quickly drawn into glass fibers with ...

Embodiment 1-6

[0059] The glass fiber was prepared by the pool kiln method. Table 1 shows the chemical composition of the glass composition of each embodiment and comparative example, and the unit is mass percentage.

[0060] Calculate the required raw material addition ratio according to the actual glass formula; according to the ratio, various raw materials are quantitatively transported to the mixing bin, fully mixed evenly, and qualified batch materials are obtained;

[0061] 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;

[0062] After the batch material is heated at 1300-1500 ℃ in the tank kiln, the qualified glass liquid is formed after melting, clarification and homogenization;

[0063] The molten glass is cooled to the molding temperature through the working channel, and then flows out through the platinum bushing plate to form glass filaments; the glass filaments are quickly drawn into glass fibers...

Abstract

The invention discloses a glass fiber with high refractive index and high performance, which comprises the following components: 54-62wt% SiO 2 ; 10‑14 wt% Al 2 o 3 ; 17‑24 wt% CaO; 0‑4.5 wt% MgO; 0‑1 wt% TiO 2 ;5.1‑10w% of Y 2 o 3 , 0‑5wt% ZnO; the ZnO and Y 2 o 3 The total amount does not exceed 10wt%; Li 2 O, Na 2 O and K 2 The sum of the mass percentages of O is 0.2-2wt%; the ZnO and Y 2 o 3 The sum of the mass percentages is not more than 10wt%. The technical problem solved by the present invention is to provide a high-refractive index, high-performance glass fiber glass fiber, which has a better matching refractive index with PC resin, and has lighter color and good mechanical properties at the same time.

Description

technical field [0001] The invention relates to the field of glass fibers, in particular to a glass fiber with high refractive index and high performance. Background technique [0002] Glass fiber is an excellent inorganic non-metallic material. It has the advantages of high tensile strength, high strength, good temperature resistance, good corrosion resistance, heat insulation, sound insulation, and non-combustibility. It is widely used in electronics, electricity, automobiles, aviation, etc. , ships, environmental protection, chemical industry, construction and other fields of the national economy. [0003] Polycarbonate (PC) is an excellent thermoplastic resin with good transparency, non-toxicity, weather and heat resistance, impact resistance, fatigue resistance and electrical properties, and has become the fastest growing general engineering among the five engineering plastics Plastics are widely used in glass assembly industry, automobile industry and electronics, ele...
