Protective agent for improving self-protection capability of cement concrete in active service and preparation method of protective agent
The invention discloses a protective agent for improving the self-protection capability of cement concrete in active service and a preparation method. The protective agent is prepared from the following raw materials in parts by weight: 2-4 parts of methyl silicone resin, 2-4 parts of orthosilicic acid, 4-10 parts of a double-alkali solution and a non-ionic surface active agent with alkali resistance, the dual-alkali solution is an aqueous solution prepared from water and soluble alkali, and the soluble alkali adopts two of lithium hydroxide, potassium hydroxide and sodium hydroxide. According to the present invention, the self-protection ability of the active cement concrete can be improved, and after the coating material is sprayed on the active cement concrete surface, the coating material can permeate into the active cement concrete to react with the active cement concrete to form the permanent whole body; according to the present invention, the self-protection ability such as water resistance, stain resistance, corrosion resistance, freeze thawing resistance, carbonization resistance, chloride ion permeation resistance, wear resistance and the like of the cement concrete in service is improved, no additional coating is provided on the surface of the cement concrete, such that the falling risk does not exist, the construction method is simple, and the application cost is low.
本发明公开了一种提升现役水泥砼自我性防护能力的防护剂及制备方法，该防护剂包括以下重量份的原料：甲硅树脂2～4份、原硅酸2～4份、双碱溶液4～10份以及具有抗碱能力非离子表面活性剂；所述双碱溶液是由水和可溶性碱制成的水溶液，并且所述可溶性碱采用氢氧化锂、氢氧化钾、氢氧化钠中的两种。本发明能够提升现役水泥砼自我性防护能力，喷涂于现役水泥砼表面后，能渗透至现役水泥砼内部，与现役水泥砼反应形成永久整体，伴随现役水泥砼的全寿命周期，提高现役水泥砼的防水、耐沾污、抗腐蚀、抗冻融、抗碳化、抗氯离子渗透、耐磨度等自我性防护能力，在水泥砼表面没有附加涂层，不会有脱落的风险，而且施工方法非常简单，应用成本低廉。
