Mildew-proof alkali-efflorescence-proof mortar and preparation method thereof
The invention discloses mildew-proof alkali efflorescence prevention mortar which comprises the following components in percentage by mass: 90%-97% of semi-hydrated phosphogypsum, 1%-3% of a mildew-proof auxiliary agent, 1%-3% of an alkali efflorescence prevention auxiliary agent, 0.05%-2% of a retarder and 0.05%-2% of a water reducing agent. The invention also discloses a preparation method of the mildew-proof and alkali-efflorescence-proof mortar, which comprises the following steps: S1, stirring and turning over the retarder and the water reducing agent respectively under a closed condition, and sterilizing while stirring and turning over; and S2, uniformly stirring and mixing the sterilized retarder and water reducer with the semi-hydrated phosphogypsum, the mildew-proof auxiliary agent and the alkali efflorescence prevention auxiliary agent, and carrying out sterilization treatment while stirring and mixing. According to the method, whole-process bacteriostasis is achieved through sterilization of the organic raw materials, sterilization in the mortar preparation process and bacteriostasis of the inorganic nano-bactericide in the using process, mildew-proof and alkali-efflorescence-proof performance of the phosphogypsum mortar is achieved by adding the alkali-efflorescence-proof agent, and the phosphogypsum mortar is more advanced and environmentally friendly compared with the prior art.
本发明公开了防霉防返碱砂浆，包括按质量百分比计的如下组份：半水磷石膏90％～97％、防霉助剂1％～3％、防返碱助剂1％～3％、缓凝剂0.05％～2％、减水剂0.05％～2％。本发明还公开了防霉防返碱砂浆的制备方法，包括如下步骤：S1、将缓凝剂、减水剂分别在密闭条件下搅拌翻动，搅拌翻动的同时进行灭菌处理；S2、将经灭菌后的缓凝剂、减水剂与半水磷石膏、防霉助剂、防返碱助剂搅拌混匀，在搅拌混合的同时进行灭菌处理。本发明的方法从有机原料灭菌、砂浆配制过程灭菌、使用过程中通过无机纳米杀菌剂抑菌实现全过程抑菌，并通过添加防返碱剂同时实现磷石膏砂浆的防霉、防返碱性能，较现有技术更为先进、环保。
