Abstract

The invention discloses a preparation method of a phosphogypsum fireproof door core board and relates to the technical field of fireproof building materials. The method includes: alkali-washing livistona chinensis leaf fibers and performing ionization surface modification; mixing raw materials in batches to prepare a thick material; pouring the thick material in a mold, allowing the material to stand, and maintaining, cutting and shaping the material. The fireproof door core board is improved significantly in aspects of mechanical strength, fireproof and waterproof properties, heat resistanceand anti-freeze effect, and oil resistance, etc., has better overall performance, is better in applicability, and is guaranteed in service life well.

Description

technical field [0001] The invention relates to the technical field of fireproof building materials, in particular to a preparation method of a phosphogypsum fireproof door core board. Background technique [0002] The fire door is composed of skeleton, door core filling material and fireproof hardware. The filling material of the door core board is the core material of the fire door, and its quality and performance are particularly important. Most of the filling materials of the existing door core board adopt materials such as rock wool, aluminum silicate wool, mineral wool, perlite board, foamed magnesium oxychloride cement board, foamed cement board. Aluminum silicate wool board, rock wool, slag wool or glass wool fireproof door panels. Although these materials are light in weight and good in heat insulation, they consume a lot of energy in the production process. Pollution, it is difficult to meet environmental protection requirements, and there are problems such as poo...
