Abstract
The invention belongs to the field of chemical industry, and particularly relates to a melamine benzalation Schiff base and a preparation method thereof. The Schiff base is prepared by taking melamine and benzaldehyde as the raw materials, by controlling the reasonable reaction temperature and raw material ratio, three amidogens in melamine can react with an aldehyde group of benzaldehyde, condensation is conducted, and a C=N structure is formed. The prepared Schiff base comprises three C=N structures, lone pair electrons on the C=N structures can play a role in transmitting electricity, and therefore the conductive function is achieved; due to a special structure of hexahydroxy nitrogen-containing heterocycles, the prepared Schiff base has multiple nitrogen atoms, and a good effect on flame retardance is achieved. In addition, the preparation method has the advantages of being simple, easy to operate and the like.
