| titleOfInvention | Nano-alumina modified silane waterproofing agent and preparation method and application thereof |
| abstract | The invention discloses a nano-alumina modified silane waterproof agent and a preparation method and application thereof. The preparation method comprises the following steps: adding an alkaline catalyst into a non-ionic composite emulsifier aqueous solution, adding a silane monomer under the conditions of heating at 60-80 ℃ and stirring, and reacting to obtain an emulsion; and cooling the emulsion to 30-50 ℃, adding modified nano alumina, and stirring for reaction to obtain the nano alumina modified silane waterproof agent, wherein the modified nano alumina is obtained by modifying a nano alumina aqueous solution with silica sol or fumed silica. The prepared silane waterproof agent has no VOC emission, good stability and good waterproof performance, can effectively prevent moisture from entering and keep the air permeability of the pore structure of the material, and can be widely applied to the field of building materials. |
