Rock wool composite board forming process
The invention discloses a rock wool composite board forming process, which belongs to the field of composite board materials, and comprises the following steps: crushing and melting ores, centrifuging at a high speed to form rock wool fibers, and spraying a proper amount of binder at the same time; adding modified aerogel and a binder, and carrying out glue mixing treatment; pre-pressing to form a rock wool fiber plate blank; and performing sectional type high-temperature curing and cutting to form a rock wool fiber board finished product. The silicon dioxide aerogel is modified, a-COOH group is introduced to the surface of the silicon dioxide aerogel, and the silicon dioxide aerogel and a self-made binder can generate a chemical bonding effect through the group, so that the binding force of the aerogel and a plate is improved, dispersion of the aerogel is promoted, and the thermal insulation effect of the aerogel is better exerted; besides, benzene rings and amino groups are introduced to molecular chains of the self-made adhesive, so that the compactness and uniformity of a cross-linked network structure can be improved, and the adhesive strength is relatively high, so that the mechanical properties, uniform compactness and other properties of the plate are improved.
本发明公开了一种岩棉复合板成型工艺，属于复合板材料领域，包括如下步骤：将矿石粉碎熔化后高速离心形成岩棉纤维，与此同时喷入适量粘结剂；加入改性气凝胶和粘结剂，进行拌胶处理；预压，形成岩棉纤维板坯；分段式高温固化，切割，形成岩棉纤维板成品。本发明通过对二氧化硅气凝胶进行改性，在其表面引入‑COOH基团，通过该基团，二氧化硅气凝胶能够与自制的粘结剂产生化学键合作用，从而提高气凝胶与板材的结合力以及促进气凝胶分散，更好的发挥气凝胶保温隔热效果；另外，自制的粘结剂在分子链上引入了苯环和氨基，能够提高交联网络结构的致密性和均匀性，具有较高的粘结强度，从而提升板材的机械性能、均匀致密性等多项性能。
