In the construction industry, waterproofing is a key link to ensure the safety of building structures and extend their service life. With the advancement of materials science, more and more high-performance waterproofing agents have been developed. Among them, methylsilicic acid, as an important raw material for the preparation of silicone waterproofing agents, has gradually occupied an important position in the field of building waterproofing due to its unique chemical properties and excellent waterproofing performance. This article aims to explore in depth the application of methylsilicic acid in building waterproofing agents and its many advantages.
1. Basic properties of methylsilicic acid
Methylsilicic acid, also known as monomethylsilicone resin, is a white granular solid refined by hydrolysis, washing, and centrifugal dehydration of monomethyltrichlorosilane. Its solid content is usually ≥65%, acid content ≤1%, and sesquioxygen content (measured in CH3SiO3) is between 36 and 50%, with good hydrophobic properties. These characteristics make methylsilicic acid an ideal raw material for the preparation of silicone waterproofing agents.
2. Preparation of methylsilicic acid waterproofing agent
Methylsilicic acid can be converted into a variety of silicone waterproofing agents through a specific chemical reaction process. During the preparation process of these waterproofing agents, the hydrophobicity of methylsilicic acid is effectively retained and further enhanced, thus giving the waterproofing agent excellent waterproof, moisture-proof and anti-seepage functions. At the same time, by adjusting the formula and process, the waterproofing agent can also be optimized in terms of breathability, anti-aging, anti-pollution, and weather resistance.
3. Advantages of methylsilicic acid waterproofing agent
Excellent waterproofing performance: Methylsilicic acid waterproofing agent can form a dense waterproof film on the surface of the substrate, effectively blocking moisture penetration and ensuring a dry environment for the building.
Good air permeability: Unlike some traditional waterproofing materials, methylsilicic acid waterproofing agent can maintain a certain air permeability while ensuring waterproof performance, which is conducive to the discharge of moisture inside the building and avoiding problems such as mildew.
Excellent anti-aging performance: Methylsilicic acid waterproofing agent has excellent weather resistance and UV resistance, and can maintain a stable waterproof effect even if used for a long time in harsh natural environments.
Environmentally friendly and pollution-free: Methylsilicic acid waterproofing agent is an environmentally friendly material, non-toxic and harmless, with no irritating odor during construction, and is friendly to the human body and the environment.
Easy construction: Methylsilicic acid waterproofing agent can be applied by spraying, brushing and other methods, which is easy and quick to operate, greatly improving the construction efficiency.
Wide range of applications: Methylsilicic Acid waterproofing agent is not only suitable for conventional waterproofing parts such as roofs, walls, and floors, but also can be used for places with high humidity such as basements, bathrooms, swimming pools, and waterproofing treatment of various substrates such as stone, wood, and concrete.
As an important raw material for the preparation of silicone waterproofing agent, Methylsilicic Acid's unique chemical properties and excellent waterproofing performance provide strong support for building waterproofing projects. With the continuous development of the construction industry and the increasing requirements for waterproofing performance, the application prospects of Methylsilicic Acid waterproofing agent will be broader. In the future, through continuous technological innovation and product research and development, Methylsilicic Acid waterproofing agent will play an important role in more fields and escort the safety, comfort and durability of buildings.
