Embodiment 1
[0025] A kind of preparation method of glass fiber covered yarn provided by the present embodiment comprises the following steps:
[0026] (1) Weigh the following raw materials by weight percentage: 53.2% silicon dioxide, 12.5% boron oxide, 0.3% sodium oxide, 12.6% aluminum oxide, 20.8% calcium oxide, 0.25% zirconia, 0.13% iron oxide, 0.22 % Porous graphene, crush and mix the weighed raw materials, mix and melt in a furnace at 1450°C to obtain high-temperature molten glass, and then use gravity to make the high-temperature molten glass pass through a spinning box to rapidly cool and unload to extract filaments to obtain Glass fibers with a fineness not greater than 0.3 denier;
[0027] (2) Immerse the glass fiber obtained in step (1) in the mixed solution of hydrochloric acid-ammonium chloride, heat to 80° C., keep the temperature for 30 min, wash with water, dehydrate and dry to obtain the pretreated glass fiber, wherein the hydrochloric acid- In the ammonium chloride mixe...
Embodiment 2
[0033] A kind of preparation method of glass fiber covered yarn provided by the present embodiment comprises the following steps:
[0034] (1) Weigh the following raw materials by weight percentage: 55% silicon dioxide, 14.1% boron oxide, 0.5% sodium oxide, 15% aluminum oxide, 15% calcium oxide, 0.1% zirconia, 0.2% iron oxide, 0.1 % Porous Graphene, after pulverizing and mixing the weighed raw materials, mixing and melting in a furnace at 1200°C to obtain high-temperature molten glass, and then using gravity to make the high-temperature molten glass pass through the spinning box to rapidly cool and unload and extract into filaments to obtain Glass fibers with a fineness not greater than 0.3 denier;
[0035] (2) Immerse the glass fiber obtained in step (1) in the hydrochloric acid-ammonium chloride mixed solution, heat to 70° C., keep the temperature for 40 min, wash, dehydrate, and dry to obtain the pretreated glass fiber, wherein the hydrochloric acid- In the ammonium chlori...
Embodiment 3
[0041] A kind of preparation method of glass fiber covered yarn provided by the present embodiment comprises the following steps:
[0042] (1) Weigh the following raw materials by weight percentage: 50% silicon dioxide, 15% boron oxide, 0.1% sodium oxide, 11.8% aluminum oxide, 22% calcium oxide, 0.5% zirconia, 0.1% iron oxide, 0.5% % Porous Graphene, crush and mix the weighed raw materials, mix and melt in a furnace at 1500°C to obtain high-temperature molten glass, and then use gravity to make the high-temperature molten glass pass through a spinning box to rapidly cool and unload to extract filaments to obtain Glass fibers with a fineness not greater than 0.3 denier;
[0043] (2) Immerse the glass fiber obtained in step (1) in the hydrochloric acid-ammonium chloride mixed solution, heat to 85° C., keep the temperature for 20 min, wash with water, dehydrate, and dry to obtain the pretreated glass fiber, wherein the hydrochloric acid- In the ammonium chloride mixed solution, ...
