Stearic acid modified organic silicon material
A stearic acid modified organic silicon material is prepared from the following raw materials: an alkane solvent, amino silicon oil, an organic tin catalyst and stearic acid monoisocyanate. The invention also provides a preparation method of the stearic acid monoisocyanate. The preparation method of the stearic acid modified organic silicon material comprises the following process steps: sequentially adding an alkane solvent, amino silicon oil, an organic tin catalyst and stearic acid monoisocyanate into a reaction kettle, heating the mixture, and carrying out constant-temperature reaction; raising the temperature and reacting at constant temperature; and cooling to room temperature to obtain the product. The waterproof coating can be internally mixed in concrete to enable the whole concrete matrix to have waterproof performance, can be sprayed on the surface of the concrete matrix in a coating form to prevent water and carbon dioxide in air and harmful ions such as sulfate and chloride ions in water from invading, and can be sprayed on the surface of the concrete matrix; therefore, under the action of double protection, the durability of the concrete is effectively improved, and the concrete is widely applied to the fields of roads, bridges, subways, tunnels and coastal defense dams.
一种硬脂酸改性的有机硅材料，它是由下述原料制成的：烷烃类溶剂，氨基硅油，有机锡催化剂，硬脂酸单异氰酸酯。还提供了所述硬脂酸单异氰酸酯的制备方法。所述硬脂酸改性的有机硅材料的制备方法包括以下工艺步骤：向反应釜中依次加入烷烃类溶剂、氨基硅油、有机锡催化剂、硬脂酸单异氰酸酯，升温，恒温反应；之后升温，再恒温反应；降温至室温，即得。本发明是一种既可以內掺拌合在混凝土中，使整个混凝土基体具有防水性能，又可以以涂料的形式喷涂在混凝土基体的表面，防止空气中的水和二氧化碳，水中的硫酸盐、氯离子等有害离子的侵入，在双重防护的作用下，有效提高了混凝土的耐久性，广泛应用于道路桥梁、地铁、隧道、海防坝等领域。
