The application research of precipitated silica as paint thickener is an important research field in the paint industry. Paint thickeners can play a role in increasing viscosity, improving fluidity and controlling the rheology of paint in paint. Precipitated silica has excellent thickening effect due to its high specific surface area and rich pore structure, making it an ideal choice for paint thickeners. The following are several aspects of research on the application of precipitated silica as a paint thickener:

Thickening effect research: By adding precipitated silica with different particle sizes and different addition amounts to the paint, study its influence on the viscosity and rheology of the paint. Analyze the thickening mechanism of silica, explore its interaction with the coating matrix, and provide a theoretical basis for optimizing the thickening effect.

Coating performance optimization: To study the effect of different particle sizes and different addition amounts of precipitated silica on the coating performance, including the hardness, abrasion resistance, adhesion and leveling of the coating film. Optimize the addition amount and dispersion of silica to achieve a balance between performance and processability.

Dispersion and stability: study the dispersibility and stability of precipitated silica in coatings, including the effect of surface modification on dispersibility, the enhancement effect of surfactants on dispersion stability, etc. Optimize dispersion and stability to prevent aggregation and settling of silica, ensuring uniformity and stability of coatings.

Environmental friendliness: study the environmental friendliness of precipitated silica in coatings, including volatile organic compound (VOC) emissions, potential impact on the environment, etc. Find more environmentally friendly silica models or formulations to meet the needs of the coatings industry for green environmental protection.

Coating performance research: Through the research of the addition of precipitated silica in the coating, its influence on the coating performance, such as the thickness, uniformity and coverage of the coating film, etc. is discussed. Optimize the addition amount and dispersibility of silica to achieve good application performance of the coating.

Coating construction technology: study the influence of precipitated silica on coating construction technology, such as spraying performance, rolling performance and brushing performance, etc. Optimize the addition amount and dispersibility of silica to improve the construction efficiency and coating quality of the coating.

Through these application studies, we can better understand the performance and application characteristics of precipitated silica as a paint thickener, provide higher performance and more environmentally friendly paint products for the paint industry, and promote the innovation and development of the paint industry.
