Problems solved by technology

The ceramic fiber building fireproof board made in this way consumes more energy in the drying process, and at the same time, there is a disadvantage of large material loss, especially the loss of silicone oil emulsion waterproofing agent during the slurry forming process. This traditional wet method Mode of production unintentionally wastes energy and materials

Abstract

The invention relates to a dry formed hydrophobic ceramic fiber building fireproof plate and a preparation method thereof. The dry formed hydrophobic ceramic fiber building fireproof plate is characterized by consisting of the following raw materials in part by weight: 50 to 90 parts of aluminium silicate fibers, 0 to 20 parts of expanded vermiculite powder, 0 to 20 parts of clay, 2 to 8 parts of resin powder, 0.2 to 0.6 parts of mineral grease and 0.1 to 0.5 parts of organic silicone emulsion. In the ceramic fiber plate prepared by the method, ceramic fibers are used as a substrate; and due to the addition of the expanded vermiculite powder (light packing) and clay packing according to a suitable proportion, the heat resistance, the fireproof performance, the heat insulation performance and the strength of the building fireproof plate can be effectively improved, and the volume, the density and the production cost of the building fireproof plate are greatly reduced. Moreover, the dry formed hydrophobic ceramic fiber building fireproof plate can be used as an upgrade product of conventional building fireproof plates such as a magnesium oxychloride inorganic fireproof plate, a calcium silicate plate and the like.

Description

Technical field [0001] The invention belongs to the technical field of ceramic fiber materials, and specifically relates to a ceramic fiber building fireproof board and a preparation method thereof. Background technique [0002] Traditional ceramic fiber building fireproof boards are generally produced by two process routes. One is to use wet vacuum forming or wet fourdrinier forming process to make ceramic fiber slurry with a moisture content of 150-250% (dry basis) The wet billet is then dried to make a product. The ceramic fiber building fireproof board made in this way consumes more energy during the drying process, and there is a large loss of materials during the slurry forming process, especially the disadvantage of large loss of silicone oil emulsion waterproofing agent. This traditional wet method The production mode inadvertently caused waste of energy and materials. The other is a dry resin thermal curing process, but the ceramic fiber dry-process board produced by t...
