Phenolic resin is earliest industrialized synthetic resin, and there is raw material to be easy to get, synthesize convenient, cheap spy for it
Point, there are good mechanical performance, against weather, corrosion resistance, water resistance and certain heat resistance, therefore be widely used in making mould
The industries such as plastics, adhesive, coating.But because the fragility of unmodified phenolic resin is larger, free formaldehyde and free
The presence of phenol causes that its harm to environment is larger, and this causes the application field of synvaren to be restricted.
Anacardol is by cashew nut shell liquid（Cashew nut oil）Middle extraction, cashew nut oil can obtain more pure waist through vacuum distillation
Fruit phenol.In commodity cashew nut oil containing about 90 % anacardol, 10 % cashew nut between diphenol and a small amount of tannic acid, glucose and
Glucoside, other polymers etc..It is cashew nut oil aboundresources, cheap, there is highly important development and application to be worth, can
It is widely used in synthetic surfactant, improvement natural rubber and ion exchange resin etc..There is the meta of phenolic hydroxyl group in anacardol
The fatty chain substituent of one 15 carbon, make anacardol that both there is the feature of phenolic compound, there is the soft of aliphatic compound again
Property, so anacardol is used as biomass modified dose of synvaren.
