The invention discloses a glass magnesium board with a waterproof function. The glass magnesium board is prepared from the following raw materials in parts by weight: 40-60 parts of light calcined magnesia, 20-30 parts of magnesium chloride hexahydrate, 20-30 parts of magnesium sulfate heptahydrate, 20-30 parts of sodium bentonite, 46 parts of glass fibers, 40-60 parts of pure water, 2-4 parts ofa brightening agent, 2-4 parts of a coupling agent, 1-2 parts of a defoaming agent and 2-4 parts of a waterproof agent. A part of magnesium sulfate heptahydrate is used for replacing magnesium chloride, a waterproof agent and a hydrophobic group with a long carbon chain are added, the hydrophobic group with the long carbon chain enables capillary pores of the glass magnesium board and the surfaceof the board to form a hydrophobic layer, the glass magnesium board with the waterproof function is obtained, and the problems that an existing glass magnesium board is poor in waterproof performanceand poor in waterproof performance are effectively solved. The problems that the strength of the product is reduced, the use effect is severely blocked and the service life is greatly shortened due tohalogenation, frosting and buckling deformation on the surface of the product in humid weather or water are solved.
本发明发明公开了一种具有防水功能的玻镁板，由以下重量份数的原料制成：轻烧氧化镁40‑60份、六水氯化镁20‑30份、七水硫酸镁20‑30份、钠基膨润土20‑30份、玻璃纤维4‑6份，纯水40‑60份、增白剂2‑4份、偶联剂2‑4份、消泡剂1‑2份以及防水剂2‑4份；使用部分七水硫酸镁代替氯化镁，且添加了一种防水剂，具有长碳链的疏水基，是一种憎水性防水剂，其长碳链的疏水基使玻镁板的毛细孔以及板的表面成为憎水层，得到了一种具有防水功能的玻镁板，有效解决玻镁板防水性能差，遇到潮湿天气或遇水时，其表面会发生返卤返霜、翘曲变形，从而使产品强度降低，使用效果严重受阻，使用寿命也大大缩短的问题。
