Method for preparing high-strength building gypsum through chemical modification of titanium gypsum
The invention discloses a method for preparing high-strength building gypsum through chemical modification of titanium gypsum. The method comprises the following steps: pretreating the titanium gypsum, mixing titanium gypsum composition materials, heating and frying the mixture, re-selecting and secondarily frying, storing impurities to prepare a finished product and the like. The additive composed of the outer glass fiber and the heavy calcium powder is adopted, the characteristics of good insulativity, high heat resistance and good corrosion resistance of the glass fiber are utilized, and the characteristics of high whiteness, high purity, soft hue, stable chemical components and the like of the heavy calcium powder are matched, so that the glass fiber and the titanium gypsum material are subjected to a comprehensive chemical reaction during heating and frying, and the heat resistance and the corrosion resistance of the glass fiber are improved. Meanwhile, a layer of colorless, transparent and uvioresistant breathable film which cannot be perceived by naked eyes can be formed on the surface of a building after the building gypsum is sprayed on the surface of the building, and when rainwater blows the film or wet air is encountered, water drops can naturally flow to prevent moisture from invading, so that the building gypsum has a good waterproof effect; and good waterproofness is achieved.
本发明公开了一种钛石膏化学改性制备高强度建筑石膏的方法，包括以下步骤：钛石膏预处理、钛石膏组成料混合、混合料加热炒制、复选二次炒制和储杂制备成品等步骤。本发明采用外玻璃纤维和重钙粉组成的外加剂，利用了玻璃纤维绝缘性好、耐热性强、抗腐蚀性好的特点，配合重钙粉具有白度高、纯度好、色相柔和及化学成分稳定等特点，使得加热炒制时，与钛石膏物料进行全面的化学反应，得到脱水的高强度的建筑石膏，同时采用水性的有机硅防水剂，能够在建筑石膏喷涂于建筑物表面后，可在其表面形成肉眼觉察不到的一层无色透明、抗紫外线的透气薄膜，当雨水吹打其上或遇潮湿空气时，水滴会自然流淌，阻止水分侵入，起到良好的防水性。
