Abstract

The invention discloses ardealite fireproof door core filler and a preparation method thereof, belongs to the technical field of door core filler processing, and aims at solving the problems that an existing fireproof door core plate is poor in mechanical property and tedious in door core plate installation. The preparation method comprises the following steps: weighing alpha type phosphogypsum, polyester fiber, redispersible latex powder, expanded foaming microbeads, fly ash microbeads, a waterproof agent, aluminum powder and lime according to component amounts, mixing to obtain composite phosphogypsum powder, mixing the composite phosphogypsum powder with water according to a mass ratio of 1: 2 to obtain a component A, mixing the aluminum powder with the lime to obtain a component B, mixing the component A with the component B according to a mass ratio of 1: 1 to obtain a liquid slurry filler, and mixing the liquid slurry filler with water according to a mass ratio of 1: 1 to obtain the waterproof material. And the liquid slurry filler is poured into the door plate cavity, the liquid slurry filler is naturally foamed for 1.5-2 h, and the liquid slurry filler is in a solid state after being foamed. The problems that a fireproof door core plate is poor in mechanical property and tedious in door core plate installation are solved, and the fireproof door core plate has the advantages of sound insulation, heat insulation, heat preservation, fire prevention, light volume weight and the like.

Description

technical field [0001] The invention belongs to the technical field of door core processing, and in particular relates to a phosphogypsum fireproof door core filler and a preparation method thereof. Background technique [0002] The door panel is composed of skeleton, door core filling material and fireproof hardware. The filling material of the door core panel is the core material to improve the performance of the door core panel. Existing door core board Most of the filling materials of the existing door core board are rock wool, aluminum silicate wool, mineral wool, perlite board, foamed magnesium oxychloride cement board, foamed cement board and other materials. Aluminum silicate wool board, rock wool, slag wool or glass wool fireproof door board, although these materials are light in weight and good in heat insulation, but high energy consumption in the production process, using organic adhesive to form, the production process and use process produce Pollution, it is d...
