Production process of refractory rock wool board
The invention relates to the technical field of rock wool board preparation, in particular to a production process of a refractory rock wool board. According to the invention, a fiber yarn mixture isprepared, an adhesive is prepared, and forming matching is conducted, so that the prepared refractory rock wool board has the advantages of low heat conductivity coefficient, high fire resistance, high hardness and durability, high bonding force and the like; asbestos and calcium carbonate are used as basic raw materials, and the fiber produced from asbestos and calcium carbonate has good flame retardance, so that thefire resistance of the refractory rock wool board is improved significantly.The polyether modified silicon is used as a defoaming agent, bubbles in the uniformly mixed materials are eliminated by the polyether modified silicon, air is retarded from entering the refractory rock wool board, and flame retardance can be achieved; sodium bentonite is used as a thickening agent of the adhesive, the compactness of the uniformly mixed materials is improved by the sodium bentonite, and bubble residues can be avoided.
本发明涉及岩棉板制备技术领域，具体涉及一种耐火岩棉板的生产工艺；本发明以制备纤维丝混合物、制备胶黏剂和成型配合，使得所制备的耐火岩棉板导热系数低、耐火性高、硬度，耐久性强、粘接力高等优点，通过石棉和碳酸钙作为基础原料使用，石棉和碳酸钙产生的纤维具有良好的阻燃性能，使得耐火岩棉板耐火性能得到显著提高，本发明中聚醚改性硅作为消泡剂，聚醚改性硅将混合均匀的物料内的气泡进行消除，火灾减缓空气进入耐火岩棉板内，可进行阻燃；钠基膨润土作为胶黏剂的增稠剂，钠基膨润土提升混合均匀的物料密实性，可避免气泡残留。
