Preparation of aldehyde ketone resin
The process of preparing aldehyde ketone resin is divided into two main stages: condensation and hardening.
The polycondensation stage involves the synthesis of polymers from formaldehyde and acetone through a polycondensation reaction. During this process, the monomer structure of the aldehyde ketone resin is generated by the condensation reaction of formaldehyde and acetone, with phenol as the buffer medium to ensure the smooth progress of the reaction.
The hardening stage is the reaction between the resin generated by the condensation reaction and the strengthening agent or hardener, forming a network structure to obtain the resin we need. During this process, various additives and fillers can be added as needed to achieve different performance indicators.
There are six main types of formaldehyde and ketone resins, including epoxidized formaldehyde resin, phenolic resin, diphenol urea formaldehyde resin, diphenol urea formaldehyde resin, phenolic aldehyde resin, and silicone aldehyde resin.
