Preparation method and application of rock wool heat preservation cotton
The invention discloses a preparation method and application of rock wool heat preservation cotton, and belongs to the technical field of heat preservation materials. Comprising the following steps: S1, preparing the following raw materials in parts by weight: 15 to 25 parts of rock wool fiber, 5 to 10 parts of modified silica sol, 20 to 60 parts of solid additive, 5 to 6 parts of modified adhesive, 40 to 50 parts of water glass, 45 to 85 parts of aging liquid, 60 to 70 parts of modified liquid and 75 to 85 parts of normal hexane; s2, blending the base materials; step S3, dipping; step S4, aging; step S5, modifying; and step S6, preparing. The modified adhesive and the modified silica sol are added, the modified adhesive contains rich active hydroxyl, benzene rings, trifluoromethyl, humic acid structures and unsaturated double bonds, can participate in the curing reaction of the adhesive and can also react with the modified silica sol, the overall crosslinking density of the rock wool heat preservation cotton coating is improved, the heat preservation performance of the rock wool heat preservation cotton coating is improved, and the service life of the rock wool heat preservation cotton coating is prolonged. The waterproof performance of the rock wool heat preservation cotton is improved, and meanwhile the weather resistance and the heat preservation performance of the rock wool heat preservation cotton are improved.
本发明公开了一种岩棉保温棉的制备方法及应用，属于保温材料技术领域，包括以下步骤：步骤S1、准备以下重量份原料：步骤S1、准备以下重量份原料：岩棉纤维15‑25份、改性硅溶胶5‑10份、固体添加物20‑60份、改性粘接剂5‑6份、水玻璃40‑50份、老化液45‑85份、改性液60‑70份、正己烷75‑85份；步骤S2、基料共混；步骤S3、浸渍；步骤S4、老化；步骤S5、改性；步骤S6、制成；本发明中加入了改性粘接剂和改性硅溶胶，改性粘接剂含有丰富的活性羟基、苯环、三氟甲基、腐植酸结构和不饱和双键，不仅能够参与粘接剂的固化反应，还能够与改性硅溶胶反应，提高岩棉保温棉涂层的整体交联密度，提高岩棉保温棉的防水性能同时，提高岩棉保温棉的耐候性和保温性能。
