Polymer material wrappage of pigment yellow 138 or derivative of pigment yellow 138, preparation method of polymer material wrappage, and downstream product of polymer material wrappage

Abstract

The invention relates to a polymer material wrappage of pigment yellow 138 or a derivative of pigment yellow 138, a preparation method of the polymer material wrappage, and a downstream product of thepolymer material wrappage. The method comprises the following steps: mixing a monoanhydride aromatic compound, an 8-aminoquinaldine compound, a solid organic acid and a thermoplastic polymer material; adjusting the reaction molar ratio of the raw materials and the mass content of pigment yellow 138 or the derivative of pigment yellow 138 in a final product so as to realize extruding or kneading of an obtained mixture and obtain the polymer material wrappage of pigment yellow 138 or the derivative of pigment yellow 138 in one step. The raw material reactants of pigment yellow 138 or the derivative of pigment yellow 138 have better dispersity in the high polymer material; therefore, pigment yellow 138 or the derivative of pigment yellow 138 can be directly generated and uniformly dispersedin the high polymer material in the extrusion or kneading process, no solvent is required to be added in the process, separation and purification are not required after the reaction is finished, the generation of three wastes in the traditional synthesis process of pigment yellow 138 or the derivative is avoided, the process flow is greatly simplified, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a polymer material wrapper of Pigment Yellow 138 or its derivatives, its preparation method and its downstream products. Background technique [0002] Pigment Yellow 138 is a high-performance organic pigment. Because of its strong coloring ability and excellent heat resistance, weather resistance and solvent resistance, it occupies a large proportion in the yellow pigment market. In addition, in addition to being used in conventional industrial fields such as coatings, inks, paints, etc., Pigment Yellow 138 is also widely used in high-tech aspects of LEDs and photosensitive films. Usually, Pigment Yellow 138 is prepared through traditional organic synthesis steps, which requires the use of a large amount of organic solvents, such as alcohols, ammonia, organic acids, and organic high-boiling solvents (including DMF, NMP, DMSO, etc.), and organic synthesis reactions to obtain crud...

Problems solved by technology

Equally, this method also can inevitably produce a large amount of waste acid, waste caustic, highly saline waste water and waste alcohol

[0005] In addition, Pigment Yellow 138 obtained by traditional organic synthesis methods is mostly not suitable for high-temperature thermoplastic resins. Although its heat resistance is as high as 300 ° C, it cannot be used for PMMA (polymethyl methacrylate), PC (poly Carbonate), PET (polyethylene terephthalate) and other high-temperature materials, such as BASF's PALIOTOLYELLOW K 0961HD (pigment yellow 138 powder product), clearly stated in its product description that the pigment is not suitable for PMMA , PC, PA (polyamide) and PET, its main application is hydrocarbon polymers, such as polyvinyl chloride, polyethylene, polystyrene, etc.
