Embodiment 1

[0013] A hydrogen-containing silicone oil emulsion type waterproofing agent, the proportion of which is calculated in the following parts by weight, is composed of 18 parts of 20 centimeters of hydrogen-containing silicone oil of 1.00% and 65 parts of water through 1 part of tetradecyl di Methyl benzyl ammonium chloride is formulated into an emulsification system, and 0.3% acetic acid is added to adjust the pH value to 3. After high-shear emulsification, a hydrogen-containing silicone oil emulsion type waterproofing agent is formed.

Embodiment 2

[0015] A hydrogen-containing silicone oil emulsion type waterproofing agent, the proportion of which is calculated in the following parts by weight, is composed of 26 parts of 35 centimeters hydrogen-containing silicone oil of 1.28% and 72 parts of water through 2 parts of dodecyl di Methyl benzyl ammonium bromide, 1 part of dodecyl dimethyl benzyl ammonium chloride and 1 part of alkylphenol polyoxyethylene ether are made into an emulsification system, and 0.6 parts of acetic acid are added to adjust the pH value to 5, After high-shear emulsification, it forms a hydrogen-containing silicone oil emulsion type waterproofing agent.

Embodiment 3

[0017] A hydrogen-containing silicone oil emulsion type waterproofing agent, the proportion of which is calculated in the following parts by weight, is composed of 35 parts of 50 centimeters of hydrogen-containing silicone oil of 1.56% and 80 parts of water through 5 parts of dodecyl di Methyl benzyl ammonium bromide and 2 parts of alkylphenol polyoxyethylene ether are formulated into an emulsification system, and 1 part of acetic acid is added to adjust the pH value to 6. After high-shear emulsification, a hydrogen-containing silicone oil emulsion type waterproofing agent is formed.

Abstract

The invention relates to a hydrogen-containing silicone oil emulsion type waterproofing agent. An emulsified system is prepared by compounding hydrogen-containing silicone oil and cationic surfactant or nonionic surfactant, weak acid is added to regulate pH value, and the emulsified system is subjected to high-shear emulsion to form a hydrogen-containing silicone oil emulsion. The hydrogen-containing silicone oil emulsion type waterproofing agent has the effects of waterproofing, moisture proofing, mould proofing, sterilization and the like, and can be widely applied to waterproofing of building materials, waterproofing, moisture proofing and mould proofing of historic buildings, and waterproofing and mould proofing of paper.

Description

technical field [0001] The invention relates to an emulsion type waterproofing agent, in particular to a hydrogen-containing silicone oil emulsion type waterproofing agent. Background technique [0002] As a new type of silicone material, hydrogen-containing silicone oil can be sprayed on the surface of various substrates in the form of solution or emulsion to form a waterproof film. It is widely used as fabric, fire extinguishing agent (dry powder), paper, metal, leather, wood, glass , cement, ceramics, marble waterproofing agent, anti-sticking agent or anti-corrosion agent, etc. [0003] At present, the hydrogen-containing silicone oil waterproofing agent is mainly solvent-based, but the solvent will pollute the environment; the emulsion type also needs to add metal catalysts, preservatives, etc. to affect the stability of the emulsion, or it can be used in a two-component compound. [0004] CN101613574B water-based polishing antifouling liquid adopts 100-500CPS hydrogen-...
