The core reason and application of silica as matting agentSilicon dioxide can become a mainstream matting agent, primarily due to its porous structure and high specific surface area, which can disrupt the regular reflection of light and regulate the glossiness of the coating.
Production Process
There are mainly two methods for preparation in industry. The first is the vapor phase method, which uses silicon tetrachloride as a raw material, hydrolyzing it in a high-temperature flame to produce nano-sized vapor-phase silicon dioxide, resulting in high purity and good dispersion. The second is the precipitation method, where sodium silicate reacts with acid to generate a precipitate, which is then washed, dried, and crushed, resulting in lower costs and suitability for large-scale production. Both processes can precisely control the particle size and porosity of silicon dioxide to meet different matting requirements.
Matting Principle
After silicon dioxide powder is added to the coating, it will evenly disperse to form tiny rough surfaces. When light strikes, it cannot form on the coating surface.
High-Performance Silica Anti-Corrosion PigmentsSilicon dioxide can become an efficient anti-rust pigment, with the core being its dense structure and chemical stability, which can build a protective barrier on the metal surface to block the erosion of corrosive factors.
Production Process
Industrial production mostly uses a modified precipitation method: sodium silicate is used as the raw material, which reacts with dilute sulfuric acid to generate silicon dioxide precipitate. After washing to remove impurities, zinc salts, chromates, and other anti-rust components are added for surface modification, and then the particle size is controlled through spray drying, ultimately obtaining a composite anti-rust pigment. This process has controllable costs and can enhance compatibility with coatings through modification.
Anti-Rust Principle
Its anti-rust effect is reflected in two aspects: first, physical shielding; silicon dioxide particles are densely packed in the coating, forming a continuous and dense barrier layer that prevents corrosive media such as water, oxygen, and chloride ions from contacting the metal substrate.
