Embodiment

[0030]Example: such asfigure 1 As shown, a liquid colorant injection device for polymer coloring includes a storage tank 10, a screw pump 20, a three-way valve 30, a solenoid valve 40, and a polymerizer 60 connected in sequence through pipelines, the solenoid valve 40 and Several sets of syringes 50 connected in parallel are arranged between the polymerization tanks 60. The storage tank 10 is provided with a thermostatic jacket 11 and a filter screen 12, the thermostatic jacket 11 is arranged around the outer side of the side wall and the lower bottom surface of the storage tank 10, and the filter screen 12 is arranged on the storage tank 10. Compared with a thermostat or a thermostatic barrel, the use of a thermostatic jacket saves resources and space, and is more convenient to install. The filter is used to prevent impurities from entering the next process. The temperature of the medium in the thermostatic jacket 11 is used to maintain the temperature of the liquid colorant in the...

Abstract

The invention relates to a device for injecting a liquid colorant used for polymer coloring. The device comprises a storage tank, a screw pump, a three-way valve, an electromagnetic valve and a polymerization kettle which are sequentially connected through a pipeline, wherein a plurality of groups of injectors connected in parallel are arranged between the electromagnetic valve and the polymerization kettle; and a guide pipe, a material inlet and a spray nozzle are arranged on the injector, the material inlet and the spray nozzle communicate with the guide pipe, the material inlet is connectedto the electromagnetic valve through a pipeline, and the spray nozzle is connected to the polymerization kettle. According to the device and method, continuous injection of the liquid colorant for polymer coloring is achieved; and the device is simple in structure, small in workload and high in polymer liquid colorant injection efficiency, and blocking and wall sticking can be reduced.

Description

Technical field[0001]The invention relates to a liquid colorant injection device, in particular to a liquid colorant injection device and method for polymer coloring which solves clogging and wall sticking, and is suitable for injecting liquid colorant into molten polymer during high-temperature polymerization.Background technique[0002]In the traditional process, the use of colorants such as masterbatch and toner for coloring is the main coloring method for plastics or fibers formed from polymer materials such as polyester and polyamide. However, the direct use of toner for coloring is likely to cause environmental pollution, and Coloring uniformity is poor, coloring power and vividness are low. Using masterbatch for coloring will face problems such as poor coloring uniformity, low vividness, and the need for secondary melting of polymer materials. Liquid colorant refers to a colorant formed by using organic solvents, polymer monomers and other liquid solvents as a carrier to disper...
