Preservative for compound concrete admixture
The invention relates to the field of building materials, in particular to a preservative for a composite concrete admixture, which is prepared from the following raw materials in percentage by mass: 10-15% of isobutyltriethoxysilane, 10-15% of triethoxysilane, 10-15% of triethoxysilane, 10-15% of triethoxysilane, 10-15% of 10%-15% of cinnamyl aldehyde; 3%-5% of isobutyl p-hydroxybenzoate; 5%-7% of polymeric polyol; 3%-6% of an SF-4000 series polycarboxylic acid type high-performance water reducing agent; 3%-5% of a perfluoroalkyl acrylic acid series additive; 3%-6% of sodium lignin sulfonate; 0.5%-3% of inorganic nanoparticles; and the balance of water. The bactericidal composition has broad-spectrum strong bactericidal activity, and has a relatively strong killing effect on viruses, bacteria, fungi and mold spores; the paint has excellent physical and chemical compatibility, does not change color in a container and a paint film, and is wide in effective pH value range; the mildew-proof validity period is long, the effect is stable, and no adverse effect is caused to the environment under the recommended use adding amount.
本发明涉及建筑材料领域，具体涉及一种复合型混凝土外加水剂的防腐剂，由以下质量百分比的原料制备而成：异丁基三乙氧基硅烷10％～15％；肉桂醛10％～15％；对羟基苯甲酸异丁酯3％～5％；聚合多元醇5％～7％；SF‑4000系列聚羧酸系高性能减水剂3％～6％；全氟烷基的丙烯酸系添加剂3％～5％；木质素磺酸钠3％～6％；无机纳米粒子0.5％～3％；余量为水。本发明具有广谱的强力杀菌性，对病毒、细菌、真菌及霉菌孢子都具有较强的杀灭作用；具有优异的物理及化学相容性，不会在容器和漆膜中变色，有效pH值范围广；防霉有效期长久，且效果稳定，在推荐使用添加量下对环境无不良影响。
