Problems solved by technology

The biggest disadvantage of these waterproofing agents is that after using one type of silicone waterproofing agent, it is very difficult to add another type of waterproofing agent, and the overcoating effect cannot be achieved.
Moreover, the penetration depth of the waterproofing agent in the base material is small, and the waterproofing effect will be lost after a certain period of natural aging.

Embodiment 1

[0015] Add heptadecafluorooctylethylenetrimethoxysilane into the stirrer and stir evenly, then pass through N 2 20 minutes at N 2 Keep adding isopropanol and mix for 20 minutes to form a pre-mixture; stir the pre-mixture for 0.5 hours to carry out aging reaction, and then package it under nitrogen protection to obtain a solvent-based silicone waterproof liquid with a surface dry time of 0.5 hours. The consumption of above-mentioned each component is as follows:

[0016] Heptadecafluorooctylethylenetrimethoxysilane 15g

[0017] Isopropanol 85g.

Embodiment 2

[0019] Add heptadecafluorooctylethylenetrimethoxysilane into the stirrer and stir evenly, then pass through N 2 25 minutes at N 2 Keep adding isopropanol and mix for 25 minutes to form a pre-mixture; stir the pre-mixture for 0.6 hours to carry out aging reaction, and then package it under nitrogen protection to obtain a solvent-based silicone waterproof liquid with a surface-drying time of 0.5 hours. The consumption of above-mentioned each component is as follows:

[0020] Heptadecafluorooctylethylenetrimethoxysilane 1g

[0021] Isopropanol 97g.

Embodiment 3

[0023] Add octyltriethoxysilane to the stirrer and stir evenly, then pass N 2 35 minutes at N 2 Keep adding isopropanol and mix for 35 minutes to form a pre-mixture; stir the pre-mixture for 0.7 hours to carry out aging reaction, and then package it under nitrogen protection to obtain a solvent-based silicone waterproof liquid with a surface-drying time of 0.5 hours. The consumption of above-mentioned each component is as follows:

[0024] Octyltriethoxysilane 99g

[0025] Isopropanol 1g.

Abstract

The invention discloses a preparing method of solvent-typed organic silicon water-proof liquid, which comprises the following steps: blending active organic silicane, active organic silicon oil and active organic silicon resin to stir evenly; aerating N2 for 20-40min; adding organic solvent under N2 to mix 20-40min; adding catalyst; forming pre-mixture; stirring the premixture for 0.5-1h to age; packing protected by nitrogen to obtain the product.

Description

technical field [0001] The invention relates to a method for manufacturing a solvent-based silicone waterproof liquid used for waterproofing treatment of porous substrates. Background technique [0002] Existing silicone waterproofing agents are water-based, paste, emulsion and powder. The biggest disadvantage of these waterproofing agents is that after using one type of silicone waterproofing agent, it is very difficult to add another type of waterproofing agent, and the overcoating effect cannot be achieved. Moreover, the penetration depth of the waterproofing agent in the base material is small, and the waterproofing effect will be lost after a certain period of natural aging. With the improvement of environmental protection requirements, the solvents of decorative materials cannot contain substances that are toxic to human health and pollute the environment. For the convenience of construction, it is required to choose different solvent types according to the change of...
