Abstract

The present invention belongs to the technical field of building materials, and specifically relates to a magnesium oxysulfate plate and a preparation method thereof. The magnesium oxysulfate plate comprises the following components in parts by weight: 200-300 parts of magnesium oxysulfate cement, 10-20 parts of alkali-resistant glass fiber, 30-50 parts of an aggregate, 10-50 parts of water, 5-10 parts of an early strength agent, 5-10 parts of a water reducing agent and 20-80 parts of a reinforcement material. The magnesium oxysulfate plate is low-cost, strength and water resistance are greatly improved; the magnesium oxysulfate plate has the advantages of lightweight, low alkali, water resistance, high-temperature resistance, no corrosion of reinforcing steel bar, and the like, and is very suitable for the production of fire protection boards, fire-resistant decorative materials and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a magnesium oxysulfide plate and a preparation method thereof. Background technique [0002] 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 mines. [0003] In the pr...
