Abstract

The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of high-strength flame-retardant waterproof glass wool. The method comprises the following steps: mixing and crushing bagasse and wheat straw; mixing and grinding a solid product, cullet, calcite and other raw materials; performing high-temperature treatment to obtain molten glass; and putting the molten glass in a glass wool centrifuge for processing and drying to obtain the high-strength flame-retardant waterproof glass wool. According to the preparation method, thebagasse and the wheat straw are subjected to hydrochloric acid soaking and alkali liquor high-temperature treatment, fiber molecules are subjected to oxidation treatment through sodium hypochlorite,the bonding effect among all components in the glass wool is improved, the impact resistance of the glass wool is improved, and the durability is enhanced; aluminum ions are introduced into plant fibers, the mechanical strength of the glass wool is improved, meanwhile, elemental aluminum is dispersed in the glass wool by using the fiber component, the flame retardant performance of the glass woolis enhanced under the condition of high temperature, and the fiber component and carbohydrate compounds are carbonized to improve the waterproof performance and mechanical strength, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a preparation method of high-strength flame-retardant and waterproof glass wool. Background technique [0002] CN201410853918.0 discloses a glass wool ceiling, which includes a glass wool board layer, a glass fiber felt layer, a gypsum coating layer, and the glass wool board layer is made of centrifugal glass wool fibers with an environmentally friendly resin binder. The mass ratio of the environmentally friendly resin binder and gypsum paint is: 85-93:7-15:2-3; the preparation method is to spray the environmentally friendly resin binder evenly on the surface of the centrifugal glass wool fiber in an atomized state, Then the cotton is collected by the cotton collector, compressed and transported into the curing furnace for curing to obtain a glass wool board, which is then veneered with glass fiber felt, and then sprayed with compressed gypsum pa...
