Desulfurized gypsum-based self-leveling mortar waterproof agent as well as preparation method and application thereof
The invention discloses a desulfurized gypsum-based self-leveling mortar waterproof agent as well as a preparation method and application thereof. The waterproof agent is oil-in-water type organic silicon emulsion; the organic silicon raw material is formed by mixing polymethyl triethoxy silane and hydroxyl silicone oil according to the mass ratio of (3-5): 1; and the emulsifier is a nonionic compound emulsifier with a hydrophilic-lipophilic balance (HLB) value of 9-11. The preparation method comprises the following steps: fully stirring and uniformly mixing the polymethyl triethoxy silane and the hydroxyl silicone oil to obtain an organic silicon raw material; the preparation method comprises the following steps: adding a nonionic compound emulsifier into an organic silicon raw material, and uniformly stirring and mixing to obtain a mixed raw material; and adding water into the mixed raw material while stirring, and continuously stirring after the water is added. The desulfurized gypsum-based self-leveling mortar waterproof agent is used for preparing desulfurized gypsum-based self-leveling mortar by using the desulfurized gypsum-based self-leveling mortar waterproof agent. The desulfurized gypsum self-leveling mortar can solve the technical problem that the existing desulfurized gypsum self-leveling mortar is limited due to poor water resistance in the use process.
本发明公开一种脱硫石膏基自流平砂浆防水剂及其制备方法和用途，该防水剂为水包油型有机硅乳液；有机硅原料为聚甲基三乙氧基硅烷和羟基硅油按照质量之比为3～5:1混合而成；乳化剂为亲水亲油平衡值HLB为9～11的非离子复合乳化剂。其制备方法为：将聚甲基三乙氧基硅烷和羟基硅油充分搅拌混合均匀，得到有机硅原料；将非离子复合乳化剂加入到有机硅原料中，搅拌混合均匀，得到混合原料；向混合原料中边搅拌边加入水，待水加入完毕后，继续搅拌即可。其用途为利用上述脱硫石膏基自流平砂浆防水剂制备脱硫石膏基自流平砂浆。本发明能够解决现有脱硫石膏自流平砂浆在使用过程中因耐水性差而受到限制的技术问题。
