Polyamide is commonly called nylon (PA) and has excellent mechanical properties, excellent chemical reagent resistance, good self-lubricating property and flexibility, so that the polyamide is widely applied to automobile parts, electric tool shells, electronic and electric appliance parts and the like, but polyamide is not resistant to strong alkali, poor in dimensional stability and notch impact and large in water absorption. These disadvantages in turn limit the application of PAs. The acrylonitrile-butadiene-styrene resin is commonly called ABS resin, and has good impact resistance, heat resistance, good chemical stability and low water absorption rate. The PA is subjected to blending modification by using the ABS to prepare the PA/ABS alloy material, so that the water absorption of the PA can be greatly reduced on the premise of improving the toughness of the PA resin, and the problem of unstable size is solved; and the ABS can also improve the tensile strength and heat resistance of ABS, reduce the viscosity of PA, improve the processability and improve the impact property and dimensional stability, so the ABS is widely developed and applied in the last two decades. However, the colorability is poor, most of which are limited to grey black, limiting further applications, especially bright orange red.

The PA resin is PA6 resin, and PA6 YH800 can be adopted.
The ABS resin comprises a first ABS resin and a second ABS resin, wherein the first ABS resin accounts for 15% of the total mass of the alloy material, and the second ABS resin accounts for 21.85-29.55% of the total mass of the alloy material. The first ABS resin is ABS 717K; and the second ABS resin is ABS HR-181.
The light stabilizer comprises a first light stabilizer and a second light stabilizer, wherein the first light stabilizer is Chimassorb 944 and accounts for 0.15% of the total mass of the alloy material; the second light stabilizer is Tinuvin 770, and accounts for 0.15% of the total mass of the alloy material.
The preparation method of the PA/ABS alloy material based on pyrene ketone dye coloring comprises the following steps: the components are uniformly mixed according to a set proportion, and then extrusion molding is carried out by adopting an extrusion process, wherein the extrusion temperature is 230-260 ℃, and the screw extrusion speed is 300-500 rpm.
In this example, when a product was prepared using a PA/ABS alloy material colored with a pyrene ketone-based dye, the equipment used included a coblon STS 50 twin-screw extruder, a Brabender loss-in-weight feeder, a 5m circulating water tank, an ormamage pelletizer, a sinki high-speed mixer, and a macbeck vibrating screen. The extrusion process is a mature molding process, and is not described in detail in this embodiment.
To verify the effectiveness of this protocol, 4-group comparative examples and 4-group examples are provided below, as shown in table 1.
TABLE 1 component ratios of the respective comparative examples and examples
Description of the drawings:
1 part of compatilizer: DENKA IP MS-NB styrene-N-phenylmaleimide-maleic anhydride copolymer;
compatilizer 2: UMG AXS Resin S601N acrylonitrile-styrene-methacrylic acid copolymer;
macrolex EG Red: LANXESS pyreneone red dye (solvent red 135);
tensile test standard: ISO527:2012;

TABLE 2 results of various performance tests carried out on the products obtained according to the compounding ratios in Table 1
The amido bond (-CO-NH-), the PA/ABS processing temperature and the color limit the red coloring performance of the PA resin, and the scheme adopts the pyrene ketone red dye to be applied to the PA/ABS alloy material, thereby greatly improving the coloring performance of the PA/ABS alloy material.
Since ABS and PA are typically non-crystalline and crystalline incompatibleIn order to improve the compatibility of the system and improve various performances of PA/ABS, a compatibility technology is adopted. However, MAH-g-ABS or similar additives (such as styrene-N-phenylmaleimide-maleic anhydride) are mostly selected as compatilizers in the market, and when the pyrene ketone red dye is used for coloring PA/ABS, the maleic anhydride grafting additives and the pyrene ketone red dye can generate chemical reaction in the blending process, and the mechanical properties of the PA/ABS alloy are greatly reduced. The performance of the produced product is not satisfactory and can not meet the performance requirement. According to the scheme, the acrylonitrile-styrene-methacrylic acid copolymer is used as the compatilizer, so that the compatilizer can be well matched with the pyreneone red dye, various mechanical properties of an extruded product are guaranteed, and the notch impact strength and the red coloring performance of the alloy material are greatly improved; the notch impact strength of the alloy material can reach 60KJ/m 2 The color of the product (bright red) is not obviously changed within three months under the condition of light protection (delta E)<1.0)。
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications, equivalents, flow charts, and other related technical fields that are made by the present invention will be included in the scope of the present invention.
