Problems solved by technology

[0003] However, magnesium oxychloride cement gelling materials also have many obvious disadvantages: poor water resistance, easy cracking, warping deformation, return to halogen and frost, etc., seriously restricting its development. Poor water resistance is manifested in: general magnesium oxychloride cement products After soaking in water for 28 days, its strength will be reduced by 70% to 80%.

Abstract

The invention discloses a waterproof glass magnesium board and a preparation method thereof and relates to the technical field of building materials. The waterproof glass magnesium board is mainly prepared from magnesium oxide, anhydrous magnesium chloride, refractory brick dust, tourmaline powder, zirconium dioxide aerogel, aluminum phosphate, silica fume, trisodium phosphate, magnesium silicofluoride, sugar calcium, styrene-butadiene latex, bamboo fibers, graphite powder, sodium dodecyl benzene sulfonate, stearic acid and the like. The waterproof glass magnesium board is good in waterproof performance through coordination of the zirconium dioxide aerogel, the aluminum phosphate, the magnesium silicofluoride, the stearic acid and the like and is improved in fireproof performance by the aid of the graphite powder, the refractory brick dust and the like, thereby being excellent in overall performance and high in applicability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-resistant glass magnesium board and a preparation method thereof. Background technique [0002] Glass magnesium plate (commonly known as magnesia plate) is made of magnesia, magnesium chloride, and water ternary system, which is made by configuring and adding modifiers. It is a magnesium cementitious material with stable performance. It is made of medium alkaline glass fiber The net is a reinforcing material, and it is a new type of non-combustible decorative material compounded with lightweight materials as fillers. Due to its excellent performance, it is widely used in building materials such as wall panels, ceiling panels, fireproof panels, waterproof panels, etc. It can replace wooden plywood to make wall skirts, window panels, door panels, furniture and other interior decoration appliances, and can also be used as a blending paint according to needs. , cl...
