Abstract

The invention discloses a water-resistant magnesium oxysulfate fire-proof plate and a manufacturing method thereof and belongs to the field of fire-proof plate production. The fire-proof plate is prepared by adding active filler into slurry, mixing, hardening under a certain condition and demoulding, wherein modified magnesium oxysulfate is taken as a base material and medium-alkali glass fiber and non-woven fabrics and other materials are taken as a skeleton. Compared with the prior art, the fire-proof door core plate disclosed by the invention has no moisture absorption, higher durability than a conventional glass magnesium plate and smooth and beautiful appearance. The fire-proof plate can be applied to the field of building fire protection, especially fire protection engineering under a humid environment and has a good popularization and application value.

Description

[0001] technical field [0002] The invention relates to the field of fireproof board production, in particular to a water-resistant magnesium oxysulfide fireproof board and a manufacturing method thereof. Background technique [0003] Glass magnesium fireproof board is one of the most widely used fireproof boards at present. It is a new type of non-combustible building compounded with magnesite cementitious material as base material, medium alkali glass fiber cloth as reinforcement material and light material as filler. sheet. It can be used as thermal insulation building wall panels, door core panels, ceiling panels, packing boxes, etc., and can replace wooden plywood to make dado, door and window frames, furniture, etc. The surface can also be painted with blending paint and clear water paint according to needs, and can be processed into various types of board surfaces. It can also be used in simple fire prevention projects in damp environments such as basements and min...
