Abstract

The invention discloses an ardealite fireproof door core plate and a preparation method thereof, belongs to the technical field of ardealite fireproof door cores, and aims at solving the problems that an existing fireproof door core plate is poor in mechanical property, short in fireproof time and large in volume weight. The invention relates to an ardealite fireproof door core board and a preparation method thereof. The ardealite fireproof door core board comprises the following components: alpha-type ardealite, fibers, redispersible latex powder, expanded foaming microspheres, fly ash microspheres, a foaming agent and a waterproof agent, the foaming agent and water are mixed and foamed by a foaming machine to obtain foam, the alpha-type phosphogypsum, the fibers, the redispersible latex powder and the waterproof agent are uniformly mixed, then water is added, stirring is performed to obtain slurry, and the slurry and the foaming liquid are combined and mixed. And adding expanded foaming microspheres and pulverized coal microspheres, uniformly stirring and mixing, pouring into a mold, curing, and leaving a factory after curing. The fireproof door core plate solves the problem of poor mechanical property of the fireproof door core plate, and 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 board processing, and in particular relates to a phosphogypsum fireproof door core board and a preparation method thereof. Background technique [0002] With the development of the construction industry and the economy, the construction industry has achieved unprecedented rapid development, and people's needs are becoming more and more diverse. The ordinary door panels can no longer meet people's needs, and the requirements for building materials for door panels are getting higher and higher. The performance of the door panel has become an important technical consideration, and it is also the focus and difficulty of door industry research and development. The performance of the door panel ultimately depends on the performance of the door core. To effectively improve the performance of the door core, it is necessary Research on technology. [0003] The door panel is composed of skeleton, door co...
