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.

preparation example Construction

[0035] A method for preparing a polymer material wrapping of Pigment Yellow 138 or its derivatives in one embodiment, comprising the following steps:

[0036] The monoacid anhydride aromatic compound, 8-aminoquinaldine compound, solid organic acid and thermoplastic polymer material are mixed, extruded or kneaded to obtain the polymer material wrapping of Pigment Yellow 138 or its derivatives.

[0037] Wherein, 8-aminoquinaldine compound, structure is as shown in formula (I):

[0038] R1, R2, R3, R4 and R5 are each independently H, methyl, ethyl, alkoxy, alkylthio or halogen.

[0039] Monoacid anhydride aromatic compound, the structure is as shown in formula (II):

[0040] X is an aromatic group (such as benzene ring, naphthalene, pyrene, anthracene, phenanthrene, etc.) or a halogenated derivative of an aromatic group.

[0041] Further, the 8-aminoquinaldine compound is one of the following compounds:

[0042] R1', R2', R3', R4', R5', R6' are each independently methy...

Embodiment 1

[0075]

[0076] Mix (40g, 140mmol) tetrachlorophthalic anhydride, (11g, 70mmol) 8-aminoquinaldine, (3g, 16mmol) citric acid and 0.5kg PMMA, extrude the reaction in a single-screw extruder, cool and dry and cut into pellets , to obtain PMMA masterbatch of yellow pigment yellow 138.

[0077] After grinding the PMMA masterbatch of Pigment Yellow 138 prepared in Example 1, toner particles are obtained, and its size distribution spectrum is as follows: Figure 4 shown. Tested by Malvern particle size analyzer, D50=4.09 μm, D99=10.6 μm.

[0078] figure 1 The reflectance spectrogram of the PMMA color masterbatch crude product of the pigment yellow 138 prepared by embodiment 1 is mixed with ABS and injected into a sheet, by figure 1 It can be seen that the plastic sheet exhibits similar absorption spectrum properties to traditional pigment yellow.

Embodiment 2

[0080] Mix (40g, 140mmol) tetrachlorophthalic anhydride, (11g, 70mmol) 8-aminoquinaldine, (3g, 16mmol) citric acid and 0.5kg PC, extrude the reaction in a twin-screw extruder, cool and dry and cut into pellets , to obtain yellow pigment yellow 138 PC masterbatch.

Abstract

The application relates to a polymer material wrapping of Pigment Yellow 138 or its derivatives, its preparation method and its downstream products. The method is by mixing monoacid anhydride aromatic compounds, 8-aminoquinaldine compounds, solid organic acids and thermoplastic polymer materials, and adjusting the reaction molar ratio between each raw material and the amount of Pigment Yellow 138 or its derivatives in the final product. Mass content, so that their mixture can be extruded or kneaded, one step to obtain the polymer material wrapping of Pigment Yellow 138 or its derivatives, because the raw material reactants of Pigment Yellow 138 or its derivatives have better presence in polymer materials Excellent dispersibility, so they can be directly generated and uniformly dispersed in polymer materials during extrusion or kneading, and this process does not require adding any solvent, and does not require separation and purification after the reaction, avoiding the traditional pigment yellow 138 or its derivatives The generation of three wastes in the process of compound synthesis greatly simplifies the process and reduces energy consumption.

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...
