Phenolic resin is the earliest resin to realize industrial production, which has the advantages of low price, easily available raw materials, simple process and excellent performance. The production capacity of phenolic resin in China is about 6.5438+500,000 tons, which will increase to more than 200,000 tons in 2000, ranking first among thermosetting resins. At present, it is facing a new situation of expanding production capacity, improving product performance, developing new varieties and improving technical level.
The production technology of granular phenolic resin by suspension method is an advanced technology pioneered by our school in China. It has passed the appraisal of the Ministry of Chemical Industry, and has been appraised as "reaching the international advanced level" by experts, and won the Science and Technology Progress Award of the Ministry of Chemical Industry. The production technology of 100 tons and 1000 tons has been successfully developed and has been running normally.
This product has a wide range of uses, and is suitable for phenolic molding compound, and its quality conforms to PF2A2 specified in the national standard GBl403-86. 13l, PF2A4. 16 1 index, and its insulation performance is superior to the national standard. It has the advantages of high strength and stable performance, and can replace imported resin to manufacture diamond grinding wheels. Used for manufacturing brake pads not only meets the national standard GB5763. 86, it also has the advantages of saving dosage, easy processing, no foaming and high yield.
Phenolic resin is produced by suspension method. Phenol, formaldehyde, dispersant and water are added into a reaction kettle, heated to the reaction temperature, discharged after a period of reaction, washed and dried to obtain the product. Compared with the traditional method, it has the advantages of simple process, energy saving, less pollution, easy control of reaction, easy realization of large-scale and automatic production, stable product quality, adjustable resin particle size between 80 mesh and 200 mesh, no need for crushing, good fluidity, easy storage and so on. All the raw materials are made in China, which is cheap and easy to obtain.
