AI Technical Summary
Technical Problem
Existing wetting agents produce films with poor mechanical properties after film formation in glass fiber reinforced epoxy resin composites, and also have poor compatibility with glass fiber.
Method used
A film-forming agent is formed by blending epoxy resin and hydroxyl-terminated polybutadiene in a specific ratio, and dodecyl glycidyl ether is added as an antistatic agent. Combined with silane coupling agent and antioxidant, a wetting agent is formed, which is then prepared by blending with glass fiber.
Benefits of technology
It improves the film-forming stability of wetting agents, reduces bubbles and pores, enhances the mechanical properties of glass fibers, reduces the defect rate, and has a simple and low-cost preparation process.
