The invention belongs to the technical field of waterproof agents, and particularly relates to a high-permeability angstrom bio-based waterproof agent and a preparation method thereof. The waterproof agent comprises the following components: sodium methylsilanolate, a plant extract, sodium sulfate, a surfactant, modified nano silicon dioxide and water, the preparation method comprises the following steps: adding the sodium methylsilanolate, the sodium sulfate, the surfactant and the modified nano silicon dioxide into water, uniformly mixing, heating under normal pressure, cooling to room temperature, aging, adding the plant extract after aging, and uniformly mixing again, thereby obtaining the product. The surfactant adopted by the invention not only can reduce the surface tension of the waterproof agent, but also can realize an anti-capillary effect with a base layer, so that the waterproof and hydrophobic effects are achieved. A large number of Si-O-Si bonds are formed on the surface of the modified silicon dioxide, and meanwhile, 3-aminopropyltriethoxysilane molecules do not react, so that the modified silicon dioxide only forms a relatively regular monomolecular layer and does not aggregate, and the dispersing performance of the modified silicon dioxide is improved.
本发明属于防水剂技术领域，具体为一种高渗透性埃米生物基防水剂及其制备方法；所述防水剂，包括以下组分：甲基硅醇钠、植物提取物、硫酸钠、表面活性剂、改性纳米二氧化硅和水；制备方法如下：将甲基硅醇钠、硫酸钠、表面活性剂和改性纳米二氧化硅加入水中并混合均匀，于常压下加热，再冷却至室温陈化，陈化完毕后加入植物提取物再次混合均匀后即得；本发明采用的表面活性剂不仅可以可以降低防水剂的表面张力，还可以与基层实现反毛细管效应，从而达到防水、憎水的效果。通过改性的二氧化硅表面形成了大量的Si‑O‑Si键，同时由于3‑氨丙基三乙氧基硅烷分子间不会反应，因而改性后的二氧化硅仅会形成较规则的单分子层而不会聚集成团，提高了改性二氧化硅的分散性能。
