Lightweight high-strength composite material and preparation method thereof
The invention provides a lightweight high-strength composite material and a preparation method thereof. The lightweight high-strength composite material is prepared from the following raw materials in parts by weight: 20-30 parts of magnesium oxide, 2-5 parts of floating beads, 0.09-0.15 part of citric acid, 4.5-11.5 parts of magnesium sulfate and 7-10 parts of water. The preparation method comprises the following steps: uniformly mixing magnesium oxide and floating beads to obtain a mixture A, and dissolving citric acid and magnesium sulfate in water at 40-50 DEG C to obtain a solution B; adding the mixture A into the solution B, stirring for 1 min at a low speed of 140 rpm, then stirring for 2-3 min at a high speed of 200 rpm or above, and finally curing at 20-30 DEG C. The prepared light high-strength composite material is small in volume weight and has high breaking strength and compressive strength.
本发明提出了一种轻质高强复合材料及其制备方法,所述轻质高强复合材料由以下重量份的原料制备:氧化镁20‑30份、漂珠2‑5份、柠檬酸0.09‑0.15份、硫酸镁4.5‑11.5份和水7‑10份;所述制备方法将氧化镁和漂珠混匀,得到混合物A,将柠檬酸和硫酸镁在40‑50℃溶解于水中,得到溶液B;将混合物A加入到溶液B中,先140rpm低速搅拌1min,然后再200rpm以上高速搅拌2‑3min,最后在20‑30℃的条件下进行养护。本发明制备的轻质高强复合材料容重小,而且具有较高的抗折强度和抗压强度。
