Surface retarder and preparation method thereof
The invention relates to the technical field of surface retarders, in particular to a surface retarder which is prepared from the following components in parts by weight: 3 to 10 parts of fulvic acid, 4 to 12 parts of a thickening component, 0.05 to 0.1 part of a regulator component, 3 to 10 parts of phosphogypsum, 2 to 8 parts of fly ash, 0.4 to 0.8 part of borax, 0.1 to 0.2 part of sodium fluosilicate, 1 to 5 parts of glucose, 0.3 to 1.2 parts of sodium salt, 0.3 to 1.2 parts of hydroxy carboxylate, 0.1 to 1 part of a corrosion inhibitor, 3 to 10 parts of deionized water, 1 to 6 parts of glycerol and 2 to 8 parts of a nonionic emulsifier. The surface retarder solves the problem of interface connection of new and old concrete, not only ensures the bonding quality of the concrete interface, but also reduces the working intensity, is not added with a preservative, is more environment-friendly to use, delays cement hardening through fulvic acid, adsorbs water molecules through a thickening component to form paste, is convenient to brush and coat, and is convenient to use. The ion concentration of each component in the paste is regulated and balanced through the regulator component, the action effect of the surface retarder is promoted, and the action depth of the surface retarder is effectively controlled.
本发明涉及表面缓凝剂技术领域，具体是一种表面缓凝剂，由以下重量份组成：3～10份富里酸、4～12份增稠组分、0.05～0.1份调节剂组分、3～10份磷石膏、2～8份粉煤灰、0.4～0.8份硼砂、0.1～0.2份氟硅酸钠、1～5份葡萄糖、0.3～1.2份钠盐、0.3～1.2份羟基羧酸盐、0.1～1份阻锈剂、3～10份去离子水、1～6份甘油、2～8份非离子乳化剂。本发明表面缓凝剂解决新旧混凝土界面连接的问题，既保证混凝土界面粘结质量，又降低工作强度，不添加防腐剂，使用更加的环保，通过富里酸延缓水泥硬化，增稠组分吸附水分子，形成膏体，便于表面缓凝剂涂刷，通过调节剂组分调节平衡膏体中各组分离子浓度，促进表面缓凝剂作用效果，有效控制表面缓凝剂的作用深度。
