specific Embodiment approach 1

[0024] Specific embodiment one: the preparation method of a kind of water-soluble concrete silane emulsion waterproofing agent of the present embodiment is carried out according to the following steps:

[0025] 1. Preparation of polymer base material: Add compound emulsifier to distilled water, turn on the magnetic stirrer at 400-600rpm, and heat to 60-80°C at the same time, until the compound emulsifier is completely dissolved in water and becomes a transparent solution, then adjust the temperature To 90 ° C, add amino silicone oil, then add 5 drops of triethylamine as a catalyst, then control the temperature of the system at 60 ~ 80 ° C, use a peristaltic pump to add the reaction monomer n-octyl triethoxy at a rate of one drop per second Silane and reflux, then add acrylic synthetic resin emulsion, react for 6 to 8 hours, cool to obtain a white emulsion; wherein, the mass ratio of the distilled water to the composite emulsifier is 5 to 10:1; the composite emulsifier consists ...

specific Embodiment approach 2

[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the mass ratio of the distilled water and the compound emulsifier described in step 1 is 10:1. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0037] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the composite emulsifier described in step one is made of 18 amine polyoxyethylene ether, iso-13 alcohol polyoxyethylene ether and dodecylsulfonic acid Sodium is composed in a mass ratio of 1:1:2. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a preparation method for a concrete silane emulsion water-proofing agent, in particular to a preparation method for a water-soluble concrete silane emulsion water-proofing agent and aims to solve the technical problems that silane emulsion is hard to prepare and poor in stability. The preparation method comprises the steps that 1, compound emulsifier is added to distilled water till the compound emulsifier is completely dissolved in the water, amino silicon oil is added, then triethylamine is added, triethoxyoctylsilane is added for flow returning, acrylic acid synthetic resin emulsion is added, reacting and cooling are carried out, and white emulsion is obtained; 2, phosphoric acid is added to the emulsion obtained in the step 1, the pH value of a system is adjusted to 6-10, the system is placed in a high-speed emulsifying machine to be emulsified, stabilizer polyethylene glycol 6000 and bactericide are added to the system, emulsification continues to be carried out through the high-speed emulsifying machine, and the water-soluble concrete silane emulsion water-proofing agent is obtained. The problem that silane emulsion is unstable and is prone to layering is solved, and hydrophobicity is further improved. The preparation method is applied to the field of preparation of water-proofing agents.

Description

technical field [0001] The invention relates to a preparation method of a concrete silane emulsion type waterproofing agent. Background technique [0002] Concrete is the most widely used building material today, but many concretes fail due to corrosion. Water plays an important role in the corrosion process, especially for concrete materials in coastal areas. Corrosion leads to failure. [0003] Traditional protective coatings on the surface of modeled concrete cover the concrete surface to block the pores of the concrete to prevent the intrusion of external moisture. The disadvantage is that when the internal moisture is discharged, the surface coating will be damaged and the coating will fail, and the concrete material itself cannot be guaranteed. It has excellent air permeability. [0004] Silane is a high-permeability waterproof material that can be sprayed on the surface of concrete to improve the waterproof, anti-fouling, dust-proof, anti-corrosion, anti-weathering ...
