I. Preparation Methods of Modified Phenolic Resin Powder

1. Raw Material Selection: Modified phenolic resin powder typically uses thermosetting phenolic resin as the base material, combined with specific modifiers such as organosilicon, polyether polyols, nano-fillers, etc., to enhance overall performance.
2. Mixing Process: The proportions of raw materials must be precisely controlled to ensure uniform dispersion of modifiers and full reaction with the base resin. Common mixing equipment includes high-speed mixers and twin-screw extruders.
3. Molding and Processing: Different molding processes (e.g., compression molding, injection molding, transfer molding) are selected based on product requirements, directly impacting the physical properties and surface quality of the final product.
4. Drying and Curing: After molding, appropriate drying is required to remove internal moisture and promote curing reactions. Temperature and time control during curing are critical to product quality.
5. Post-Processing: To further improve performance, heat treatment, surface finishing, or other post-processing steps (e.g., tempering, coating, sanding) may be employed.
