Problems solved by technology

However, with the development of science and technology and the continuous improvement of people's needs, ABS can no longer meet the actual needs in the following two aspects: 1) The heat distortion temperature of ABS is only about 85°C, and its heat resistance needs to be further improved; 2) ABS is easy to use. Combustible materials need to be flame retardant modified
[0003] CN 102391608A discloses an ultra-high heat-resistant flame-retardant ABS composition and a preparation method thereof. The flame-retardant performance of ABS is improved by adding a bromine-containing flame retardant an

preparation example Construction

[0052] The preparation method of above-mentioned flame-retardant ABS / POK alloy comprises the following steps:

[0053] 1) Dry the raw materials first, and then add each raw material into the mixer to fully stir and mix evenly;

[0054] 2) Transfer the raw materials in the mixer to a twin-screw extruder, extrude, cool, granulate, and dry to obtain a flame-retardant ABS / POK alloy.

[0055] Preferably, the drying described in step 1) is carried out at 80-100° C., and the drying time is 1-2 hours.

[0056] Preferably, the rotation speed of the stirrer in step 1) is 400-800 r / min, and the stirring time is 6-10 min.

[0057] Preferably, in step 2), the temperature of each temperature zone of the twin-screw extruder is 150-230° C., the feeding speed is 12-24 r / min, and the main engine speed is 220-600 r / min.

Embodiment

[0060] The raw material composition of the flame-retardant ABS / POK alloy of Examples 1-8 and the heat-resistant flame-retardant ABS of Comparative Examples 1-2 is shown in the following table (parts by mass):

[0061] Table 1 The raw material composition table of the flame-retardant ABS / POK alloy of Examples 1-8 and the heat-resistant flame-retardant ABS of Comparative Examples 1-2

[0062]

[0063] Dry the above-prepared raw materials at 85°C for 2 hours, and then put them into a high-speed mixer and stir for 10 minutes at a speed of 600 rpm. Put the mixed raw materials into the twin-screw extruder to extrude, cool, granulate and dry. The 11 temperature zones of the twin-screw extruder are respectively set to 150°C, 190°C, 220°C, 220°C, 220°C, 220°C, 215°C, 215°C, 215°C, 215°C, and 220°C. The feeding speed is 15 rpm, and the host speed is 350 rpm.

Abstract

The invention discloses a flame-retarding ABS/POK alloy and its preparation method. The flame-retarding ABS/POK alloy is prepared from, by mass, 30-65 parts of ABS resin, 10-45 parts of polyketone resin, 13-25 parts of flame retardant, 3-8 parts of flame retardant synergist, 2-5 parts of compatilizer, 0.3-1 part of antioxidant, and 0.3-1 part of processing aid. The preparation method includes steps of 1), raw material drying and blending; 2), extrusion, cooling, prilling and drying of raw materials through a dual-screw extruder. The flame-retarding ABS/POK alloy is excellent in heat resistance, and the highest thermal deformation temperature is up to 130 DEG C; the flame-retarding ABS/POK alloy has very good physical performance, flame retarding performance and processing performance; therefore, the application scale of the ABS material is greatly widened, and the preparation technique is simple and convenient to large-scale production.

Description

Technical field [0001] The invention relates to a flame-retardant ABS / POK alloy and a preparation method thereof, and belongs to the technical field of flame-retardant polymer alloy materials. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene. Acrylonitrile gives it good solvent and oil resistance, styrene gives it good processing properties, and butadiene gives it excellent impact resistance. It can be widely used in automobiles, home appliances, electronics and other fields. However, with the development of science and technology and the continuous improvement of people's needs, ABS can no longer meet actual needs in the following two aspects: 1) The heat deformation temperature of ABS is only about 85°C, and its heat resistance needs to be further improved; 2) ABS is easy to use flammable materials need to be flame-retardant modified. [0003] CN 102391608A discloses an ultra-high heat-resistant flame-retardant ABS compositi...
