Magnesian cementing material binder, composite wall material and preparation method of composite wall material
The invention relates to a magnesium binding material binder, a composite wall material and a preparation method of the magnesium binding material binder, and the magnesium binding material binder comprises the following components in parts by weight: 800-1100 parts of a magnesium binding material, 30-200 parts of fly ash, 10-50 parts of silica fume, 100-500 parts of sand for construction, 2-10 parts of phosphoric acid or phosphate, 400-600 parts of water and 10-70 parts of wood fiber. The fly ash and the silica fume are doped to physically and chemically modify the magnesium oxychloride cement binder, phosphoric acid or phosphate is doped to form a compact indissolvable magnesium phosphate protective film on the surface of a hydration product, the water resistance is improved, moisture absorption and halogenation or deformation are not prone to occurring, the contact face between the binder and a wood-bamboo board is more compact, and the service life of the binder is prolonged. The construction sand is doped to reduce the expansion rate of the magnesium cementing material binder, the composite wall material is not easy to crack, warp and the like, the wood fiber is doped to reduce the volume weight of the cement binder, and the magnesium cementing material has the characteristics of high fire resistance, light weight, fire resistance, heat insulation effect and the like compared with ordinary cement.
本发明涉及一种镁质胶凝材料粘结剂和一种复合墙材及其制备方法，镁质胶凝材料粘结剂以重量份计，包括以下组分，镁质胶凝材料800～1100份、粉煤灰30～200份、硅灰10～50份、建设用砂100～500份、磷酸或磷酸盐2～10份、水400～600份和木质纤维10～70份。掺入粉煤灰和硅灰对氯氧镁水泥粘结剂进行物理和化学的改性，掺入磷酸或磷酸盐在水化产物表面形成了致密的难溶磷酸镁保护膜，提高了耐水性能，不易吸潮返卤或变形，粘结剂与木‑竹板之间接触面更加密实，掺入建设用砂降低了镁质胶凝材料粘结剂的膨胀率，复合墙材不易发生开裂、翘曲等现象，掺入木质纤维，降低了水泥粘结剂自身的容重，镁质胶凝材料较普通水泥耐火程度高，具有轻质、防火和保温隔热效果等特质。
