Spherical thermosetting fluorescent pigment production system

Abstract

The invention relates to a spherical thermosetting fluorescent pigment production system. The system contains a production reaction assembly and a drying assembly which is arranged behind the production reaction assembly. The system has a simple structure and is convenient to operate. According to the system, a high-pressure homogenizer is used to eliminate shearing blind-angle, and particle size distribution of a spherical thermosetting fluorescent pigment is narrower (1-3 microns). As an electric-gasoline complementary heating mode is used during the drying segment, accurate temperature control is realized, crosslinking density of resin is raised, and anti-bleeding performance is more excellent. The system provided by the invention can completely meet requirements of printing ink industry.

Description

technical field [0001] The invention relates to a spherical thermosetting fluorescent pigment production system. Background technique [0002] During the production of fluorescent pigments, when heated, some volatile substances with small molecular weight escape to the outside of the reactor to pollute the production environment and endanger the health of employees. Not only that, the spherical fluorescent pigments produced by the traditional single high-shear emulsification production method have The dead angle of shearing leads to a wide particle size distribution of 5-10um. The traditional box or rake drying method takes a long time, uneven heating, and inability to accurately control the drying temperature, resulting in low crosslinking density and serious bleeding, which does not meet the requirements of the downstream ink industry. application performance requirements. Contents of the invention [0003] In order to solve the above problems, the present invention pro...
