Embodiment 1
[0032] A preparation method of modified red mud alkali-resistant glass fiber and the prepared alkali-resistant glass fiber, the ingredients are as follows:
[0033] In parts by weight, the components and dosage of the glass fiber batch (100 parts in total) are: red mud 20.7, SiO 2 59.3, Al 2 o 3 8.5, Na 2 O 0.7, CaO 6.5, MgO 4.2, TiO 2 0.1.
[0034] The experimental steps are: 1) Raw material pretreatment: Put the red mud into a high-temperature furnace and treat it at 650°C for 130 minutes to remove moisture and other impurities in the ingredients, then grind and pass through a 200-mesh sieve to make the final product The particle size and composition of the red mud are uniform and stable.
[0035] 2) Mixing: According to the ratio of raw materials, weigh each raw material and mix them evenly. The mixing time is 25 minutes.
[0036] 3) Melting: Melt the uniformly mixed batch at 1515°C and keep it warm for 120 minutes to obtain a uniform glass melt.
[0037] 4) Drawin...
