Plastic colorant fluorescent red GK and preparation method thereof

The invention belongs to the technical field of plastic colorants, and particularly relates to a plastic colorant fluorescent red GK and a preparation method thereof. The plastic colorant fluorescentred GK comprises the following raw materials in parts by weight: 37-39 parts of ethylene glycol monoethyl ether, 0.9 - 1.1 parts of malononitrile and 4.9- 5.1 parts of 3 -(1H-benzimidazole -2-yl)-N, N-diethyl -2-imine -2H-1-benzopyran- 7-amine. The preparation method of the plastic colorant fluorescent red GK comprises the following steps: 1) condensation: sequentially adding ethylene glycol monoethyl ether, malononitrile and 3- (1H-benzimidazole- 2-yl)-N, N-diethyl -2-imine -2H-1-benzopyran -7-amine in proportion into a condensation kettle, heating to 125-135 DEG C, reacting for 5.5-6.5 hours, cooling to 45-55 DEG C, discharging, and filtering to obtain a filter cake; and 2) filtering and drying: drying the filter cake in an environment with normal pressure and a temperature of 60-80 DEGC to prepare the plastic colorant fluorescent red GK. The preparation method of the plastic colorant fluorescent red has the characteristics of short reaction time, mild reaction conditions, low equipment requirements and high reaction yield.
