Hydrophobic ultralow-density ceramsite sand proppant and preparation method thereof
The invention relates to the technical field of ceramsite sand, in particular to a hydrophobic ultralow-density ceramsite sand proppant and a preparation method thereof.The preparation method of the hydrophobic ultralow-density ceramsite sand proppant comprises the following steps that powder composed of red mud, ardealite, coal cinder, titanium gypsum and fly ash is ground, and mixed powder is obtained; aluminum oxide magnetic beads and silicon dioxide magnetic beads are added into the mixed powder to be ground, and magnetic bead mixed powder is obtained; adding slurry consisting of polyamide, N-(aminoethyl)-aminopropyltriethoxysilane, carboxymethyl cellulose and acetyl triethyl citrate into the magnetic bead mixed powder, and grinding, so as to obtain magnetic bead mixed slurry; drying, crushing, screening and granulating the magnetic bead mixed slurry to obtain a ceramsite sand semi-finished product; and firing, cooling and screening the ceramsite sand semi-finished product to obtain the hydrophobic ultralow-density ceramsite sand proppant. The hydrophobic ultralow-density ceramsite sand proppant obtained by the invention is lower in density and lower in water absorption rate.
本发明涉及陶粒砂技术领域，具体涉及一种疏水性超低密陶粒砂支撑剂及其制备方法，本发明疏水性超低密陶粒砂支撑剂的制备方法包括以下步骤：将由赤泥、磷石膏、煤渣、钛石膏和粉煤灰组成的粉料进行研磨，得到混合粉料；将氧化铝磁珠和二氧化硅磁珠加入到混合粉料中进行研磨，得到磁珠混合粉料；将由聚酰胺、N‑(氨乙基)‑氨丙基三乙氧基硅烷、羧甲基纤维素和乙酰柠檬酸三乙酯组成的浆料加入到磁珠混合粉料中进行研磨，得到磁珠混合浆料；将磁珠混合浆料进行干燥、粉碎、筛分、造粒，得到陶粒砂半成品；将陶粒砂半成品进行烧制、冷却、筛分，得到疏水性超低密陶粒砂支撑剂。本发明得到的疏水性超低密陶粒砂支撑剂的密度更低、吸水率更低。
