Problems solved by technology

[0003] At present, most of the high-quality silicone waterproofing agents used in engineering are imported from abroad. Domestic silicone waterproofing agents still have the following technical disadvantages: 1. The surface of the carcass is easy to return to alkali, which directly affects the appearance and service life of the waterproofing agent. It is also greatly reduced; 2. It is easy to cause cracks and water seepage due to changes in ambient temperature, which will affect the overall waterproof effect

Abstract

The invention belongs to the field of building materials and provides a neutral organosilicone waterproofing agent. The neutral organosilicone waterproofing agent is prepared from 20-30 parts by weight of a sodium methylsilanolate water-repellent agent, 20-30 parts by weight of a sodium hydroxide solution with a mass concentration of 25%, 15-25 parts by weight of tap water, 5-10 parts by weight ofpolysiloxane, 5-10 parts by weight of organosilicone, 1-5 parts by weight of ethylene glycol, 1-5 parts by weight of lignin, 1-5 parts by weight of sodium citrate and 1-5 parts by weight of aluminumsulfate. The neutral organosilicone waterproofing agent improves the acidity and alkalinity of the organosilicone waterproofing agent, reduces an alkali return rate, prolongs a service life of the organosilicone waterproofing agent, guarantees the waterproof performances, has high environmental friendliness and is suitable for sustainable development and application.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a neutral organic silicon waterproofing agent. Background technique [0002] At present, many structural parts of housing buildings have waterproof requirements, and polymer coating waterproofing is undoubtedly a relatively good choice. Silicone waterproofing agent is a high-quality new high-efficiency waterproof material. It not only forms a uniform film, but also has a smooth surface, dustproof and dirt-resistant, and has little pollution to the environment. It is a direction for the development of waterproof materials at present. [0003] At present, most of the high-quality silicone waterproofing agents used in engineering are imported from abroad. Domestic silicone waterproofing agents still have the following technical disadvantages: 1. The surface of the carcass is easy to return to alkali, which directly affects the appearance and service life of the waterpro...
