Abstract

The invention discloses a preparation method of a magnesium oxide board, and belongs to the technical field of decoration materials of buildings. The preparation method comprises the following steps of uniformly stirring and mixing rice husk, quicklime and water, sealing and standing, and filtering, so as to obtain rice husk and quicklime mixed wet material; stirring light burning powder, hydrochloric acid and polyethylene glycol to react at constant temperature, filtering to obtain filtrate, and uniformly stirring and mixing with the light burning powder, magnesium chloride hexahydrate and the rice husk and quicklime mixed wet material, so as to obtain slurry; paving one layer of nonwoven cloth and one layer of magnesium oxide cloth at the bottom of a die, pouring the slurry into the die, forming, paving one layer of magnesium oxide cloth and one layer of nonwoven cloth, and drying, so as to obtain a blank of the magnesium oxide board; moving into a curing chamber to cure, fumigating by nitrogen carrying trimethylaluminum in the curing period, and discharging material after the curing is finished, so as to obtain the magnesium oxide board. The preparation method has the beneficial effects that the better property of resisting moisture absorbing and halogen reforming is realized; the bending strengths in dry and wet states are high; the weight increasing rate is low after moisture absorbing; the deformation of the magnesium oxide board in the use process is effectively avoided; the magnesium oxide board is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to a method for preparing a glass magnesium board, which belongs to the field of building decoration materials. Background technique [0002] Glass magnesium plate (commonly known as magnesium oxide plate) is a magnesia cementitious material with stable performance made of magnesium oxide, magnesium chloride and water as a ternary system, configured and added with a modifier. It is also a medium-alkaline glass fiber mesh It is a new type of non-combustible decorative material compounded with lightweight materials as fillers for reinforcing materials. Material composition for the production of glass magnesium board: active high-purity magnesium oxide, high-quality magnesium chloride, alkali-resistant glass fiber cloth, extremely flexible plant fiber, non-combustible and light perlite, chemically stable lithopone, high-molecular polymer, high-performance modified sex agent. Glass magnesium board is a structure that can be made int...
