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 parts ~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.

Abstract

The invention provides a preparation method for a concrete silane paste impregnation waterproof agent, relates to a preparation method for an impregnation waterproof agent, and aims to solve the problems that the adhesion of existing liquid silane and silane emulsion is poor. The preparation method comprises the following steps: 1, weighing; 2, mixing to obtain a mixed solution; 3, performing initial reaction to obtain a reactant; 4, emulsifying to obtain the concrete silane paste impregnation waterproof agent. The preparation method has the advantages that the shortcoming of poor adhesion of liquid silane and silane emulsion is overcome, the construction is convenient, and multiple construction manners such as spraying, brushing and roll coating can be adopted for coating of vertical surfaces, so that the loss of active substances is reduced; the permeability of a pore structure of the material per se can be maintained; the waterproofness and permeability of the concrete silane paste impregnation waterproof agent are better than those of liquid silane and silane emulsion, the water absorption of a concrete structure can be reduced by 90% or above, the penetration depth of silane is increased, and silane can penetrate into the concrete surface at 3-4 mm. The method is mainly used for preparation of the concrete silane paste impregnation waterproof agent.

Description

technical field [0001] The invention relates to a preparation method of impregnated waterproofing agent. Background technique [0002] Concrete is the most widely used building material in civil engineering today, but many concrete materials fail prematurely due to various reasons, some are caused by improper structural design, but most of them are caused by insufficient durability and corrosion of the structure. , water plays a very important role in the corrosion process, especially the concrete materials in coastal areas are eroded due to the humid moisture in the sea and air, and the chloride salts rich in sea water invade the interior of the concrete structure, cause it to fail due to corrosion. [0003] Traditional concrete surface protective coatings, such as asphalt, polyurethane, acrylic resin, etc., are modeling coatings, which block the pores of concrete by covering the concrete surface to prevent the intrusion of external moisture. However, the biggest disadvan...
