Waterproof rock wool board for building outer wall
The invention provides a waterproof rock wool board for a building outer wall. The waterproof rock wool board comprises the following raw materials in parts by weight: 40-55 parts of rock wool, 5-15 parts of glass fibers, 10-20 parts of kaolin, 10-20 parts of bauxite, 5-10 parts of silicon dioxide, 5-10 parts of sodium silicate and 0.5-2 part of a water repellent. The production method comprises the following steps: (1) grinding and crushing the raw materials, proportionally mixing the ground raw materials, adding a certain amount of water, uniformly stirring, and pouring into a reinforcing mesh mold for molding; (2) placing the wet rock wool board formed in the step (1) in a vacuum environment, drying, and pressing the dried rock wool board by using a pressure mold to obtain a rock wool board; and (3) spraying a waterproof coating on the surface of the rock wool board to obtain the waterproof rock wool board. The glass fibers, the kaolin, the bauxite and the silicon dioxide are used for modification, so that the tensile strength and the high-temperature resistance of the rock wool board are improved; the rock wool board has good waterproof performance by adding the organic siliconwater repellent and spraying the waterproof coating.
本发明提供了一种建筑外墙用防水岩棉板，包括以下重量份原料：岩棉40‑55份、玻璃纤维5‑15份、高岭土10‑20份、铝矾土10‑20份、二氧化硅5‑10份、硅酸钠5‑10份、憎水剂0.5‑2份。生产方法，包括以下步骤：（1）将各原料研磨粉碎，将研磨后的各原料按比例混合，再加入一定量的水，搅拌均匀后倒入钢筋网模具中成型；（2）将步骤1中成型的湿岩棉板置于在真空环境中干燥，再用的压力模具进行压制，得到岩棉板；（3）在岩棉板表面喷涂防水涂料，得到防水岩棉板。本发明通过玻璃纤维、高岭土、铝矾土、二氧化硅改性，提高了岩棉板的抗拉强度和耐高温性能，通过添加有机硅憎水剂并喷涂防水涂料，使岩棉板具有良好的防水性能。
