specific Embodiment approach 1
[0010] Embodiment 1: This embodiment is a method for preparing concrete silane paste impregnated with waterproofing agent, which is specifically completed according to the following steps:
[0011] 1. Weighing: Weigh 50-80 parts by weight of n-octyltriethoxysilane, 1-6 parts of octadecylamine polyoxyethylene ether, 1-10 parts of isotridecanyl polyoxyethylene ether, 0.15 ~2 parts of triethylamine, 1~6 parts of sodium dodecylbenzenesulfonate, 0.1~2 parts of polyethylene glycol 6000, 0.1~0.5 parts of bactericide, 0.1~0.5 parts of defoamer and 20~50 parts of water ; 2. Mixing: Add 1 to 6 parts of octadecylamine polyoxyethylene ether, 1 to 10 parts of isotridecanyl polyoxyethylene ether and 1 to 6 parts of sodium dodecylbenzenesulfonate as a compound emulsifier to 20 ~50 parts of water, stirring and mixing at a stirring speed of 300rpm~500rpm, while stirring and mixing starts, the temperature is raised from room temperature to 50~70°C, and after the temperature is raised to 50~70°C...
specific Embodiment approach 2
[0018] Specific embodiment two: the difference between this embodiment and specific embodiment one is: in step one, weigh 60-80 parts of n-octyltriethoxysilane, 1-6 parts of octadecylamine polyoxyethylene Ether, 1-10 parts of isotridecanyl polyoxyethylene ether, 0.15-2 parts of triethylamine, 1-6 parts of sodium dodecylbenzenesulfonate, 0.1-2 parts of polyethylene glycol 6000, 0.1-0.5 parts Fungicide, 0.1-0.5 parts of defoamer and 20-40 parts of water. Others are the same as the first embodiment.
specific Embodiment approach 3
[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step one, 60-80 parts of n-octyltriethoxysilane and 2-5 parts of octadecylamine are weighed in parts by weight Polyoxyethylene ether, 2-6 parts of isotridecanyl polyoxyethylene ether, 0.15-2 parts of triethylamine, 1-3 parts of sodium dodecylbenzenesulfonate, 0.1-2 parts of polyethylene glycol 6000, 0.1 ~0.5 parts of fungicide, 0.1~0.5 parts of defoamer and 20~40 parts of water. Others are the same as those in Embodiment 1 or 2.
