Composite aluminum-magnesium paste and preparation method thereof
The invention discloses a composite aluminum-magnesium paste material and a preparation method thereof, and the composite aluminum-magnesium paste material comprises the following components in percentage by weight: 30-40% of sepiolite fabric, 30-40% of inorganic fiber, 10-20% of nanoscale fumed silica micropowder, 2-4% of lightweight aggregate, 4-7% of hollow glass beads, 0.5-1% of an additive silane coupling agent KH-550, 0.3-0.6% of hydrated alumina, 0.2-0.4% of water glass, 0.5-1% of a penetrant T and 1-2% of silane group powder. The preparation method of the composite aluminum-magnesium paste comprises the following steps: proportioning, pulping and filtering, filling into a mold, sizing, performing a waterproof process, performing high-temperature decomposition treatment, packaging, storing and using. The composite aluminum-magnesium paste disclosed by the invention has the advantages of low heat conductivity coefficient, small heat loss, long service life, A-grade noninflammability and hydrophobicity, can be applied to heat preservation of equipment surfaces such as boilers and pipelines and special-shaped parts, and is particularly suitable for heat preservation and repair of buried pipelines.
本发明公开了一种复合铝镁质膏料及其制备方法，复合铝镁质膏料按照重量百分比包括以下组分：海泡石绒30～40％，无机纤维30～40％，纳米级气相二氧化硅微粉10～20％，轻质骨料2～4％，空心玻璃微珠4～7％，添加剂硅烷偶联剂KH‑550 0.5～1％，水合氧化铝0.3～0.6％，水玻璃0.2～0.4％，渗透剂T 0.5～1％，硅烷基粉末1～2％；该复合铝镁质膏料制备方法包括配料、打浆过滤、灌模、定型、防水工艺、高温分解处理、包装和储藏、使用。本发明中复合铝镁质膏料具有导热系数低、热损失小、使用寿命长、A级不燃，且憎水，可应用在锅炉、管道等设备表面、异形件保温，特别适用于地埋管道的保温修复。
