Problems solved by technology

[0002] Furfural acetone resin is a kind of furan resin, which has good miscibility with many thermoplastic and thermosetting resins, so it can be modified by mixing with epoxy resin or phenolic resin. After modification, furfural acetone resin material can have acid resistance Alkali, resistance to organic solvents, strong weather resistance, etc., and furfural acetone resin has a wide range of sources, simple production process, and low cost. It is mainly used to make various corrosion-resistant and high-temperature materials in the cable production industry. However, furfural acetone resin preparation During the process, high brittleness, poor cohesiveness and poor process stability
