THE PROCESS FOR PREPARING HIGH POLYMERIZED URUSHIOL FROM NATURAL LACQUER AND INDUSTRIAL LACQUER-GOLD PAINTSCOATING MATERIALS

摘要

PURPOSE: A manufacturing method of a high-polymerized urushiol polymer is provided to provide a high-polymerized urushiol polymer not scattering particles to air by using reformed urushiol, and having excellent compatibility with various vehicles. CONSTITUTION: A manufacturing method of a high-polymerized urushiol polymer comprises: a step of generating urushiol polymer by condensation polymerization of urushiol and formaldehyde under the presence of a basic catalyst; a step of removing a part of whole part of residual formaldehyde from the urushiol polymer; and a step of manufacturing high-polymerized urushiol through polymerization by heating the urushiol polymer under the presence of an inert gas. The urushiol is originated from natural lacquer.
