Fumed silica is a new inorganic nanomaterial, also known as fumed silica. It is widely used in coatings and inks, adhesives and sealants, plastics, rubber, food, medicine, chemical mechanical polishing, catalyst carriers and other industries and fields. It is commonly used as thickener, thixotropic agent, anti-settling agent, anti-sag agent, matting agent and defoaming agent in liquid systems. It can be used as anti-caking agent and flow aid in solid powder, with excellent chemical stability and thermal stability.

Two-component epoxy wind energy blade adhesive is mainly used for wind turbine blade bonding, internal electromechanical sealing, hub and bearing bonding. Due to the advantages of epoxy adhesive such as small curing shrinkage, excellent workmanship, and good chemical stability, it has become mainstream. Structural adhesives are used for wind turbine blades.

Wind energy has been a key area and direction of research and development, exploration and layout in recent years. By studying the application and changes of fumed silica in epoxy wind power adhesives, we compared the hydrophilic fumed silica with the hydrophobic one obtained after the hydrophilic treatment. The experimental performance of fumed silica provides constructive new ideas and methods for improving the performance of wind turbine adhesives.

A series of experimental research results show that fumed silica as an inorganic thickener can effectively improve the viscosity and thixotropy of epoxy leaf glue, and hydrophobic products have better thickening effects and thixotropy.

Fumed silica serves as a filler, reinforcing agent, and thickener. When added to the epoxy wind power adhesive at the recommended dosage of 6%-8%, it can improve the mechanical properties, wear resistance, and weather resistance of the rubber, which is helpful to Improve the strength and life of wind energy blade glue.
