preparation example Construction

[0021] A preparation method of flame-retardant ABS masterbatch, is characterized in that, comprises the following steps:

[0022] a: Weigh the carrier resin and flame retardant according to the ratio of parts by mass, and mix them evenly;

[0023] B: take by weighing zinc stearate and the mixture in a according to the proportioning of parts by mass, and mix uniformly;

[0024] c: Put the mixed raw materials in b into the hopper of the twin-screw extruder, melt and extrude, and granulate to obtain the flame-retardant masterbatch; the processing technology is as follows: the temperature in the first zone of the twin-screw extruder is 200-210°C, The temperature in the second zone is 220-240℃, the temperature in the third zone is 220-240℃, the temperature in the fourth zone is 220-240℃, the temperature in the fifth zone is 220-240℃, the temperature in the sixth zone is 220-240℃, the temperature in the seventh zone is 220-240℃, and the temperature in the eighth zone 220-240°C, the...

Embodiment 1

[0027] Three kinds of carrier resins are respectively 100 parts by mass parts, DBDPO60 parts, Sb 2 o 3 40 parts, 5 parts of zinc stearate, mixed at high and low speed for 3-5 MIN. Afterwards, the mixed materials are put into the hopper of the twin-screw extruder, melted and blended, extruded and granulated to form a composite material. Among them, the processing temperature settings of each zone of the screw are: the temperature of the first zone is 200-210°C, the temperature of the second zone is 220-240°C, the temperature of the third zone is 220-240°C, the temperature of the fourth zone is 220-240°C, the temperature of the fifth zone is 220-240°C, The temperature of the sixth zone is 220-240°C, the temperature of the seventh zone is 220-240°C, the temperature of the eighth zone is 220-240°C, the temperature of the die head is 200-220°C, the residence time is 1-2min, and the pressure is 10-16MPa.

Embodiment 2

[0029] Three kinds of carrier resins are respectively 100 parts by mass parts, DBDPO70 parts, Sb 2 o 3 35 parts, 4 parts of zinc stearate, mixed at high and low speed for 3-5min. Afterwards, the mixed materials are put into the hopper of the twin-screw extruder, melted and blended, extruded and granulated to form a composite material. Among them, the processing temperature settings of each zone of the screw are: the temperature of the first zone is 200-210°C, the temperature of the second zone is 220-140°C, the temperature of the third zone is 220-240°C, the temperature of the fourth zone is 220-240°C, the temperature of the fifth zone is 220-240°C, The temperature of the sixth zone is 220-240°C, the temperature of the seventh zone is 220-240°C, the temperature of the eighth zone is 220-240°C, the temperature of the die head is 200-220°C, the residence time is 1-2min, and the pressure is 10-16MPa.

Abstract

The invention is suitable for the field of polymer, and provides a flame retardant ABS master batch and a preparation method thereof. The method uses a DBDPO / Sb2O3 composite flame retardant system, which comprises 60-80 parts of DBDPO, 30-40 parts of Sb2O3, 100 parts of different carrier resin and other adjuvants. Various flame retardant master batches are prepared through melt blending and extrusion granulation, and then are mixed with ABS to make performance contrast research, thus the ABS master batch, which takes CPE as carrier resin and has good flame retardance and other performances, is obtained. The flame retardant master batch prepared by the invention has small influences on other performances of ABS resin, can reach UL94 V0-level flame retardance, has simpler processing technology, and provides conditions for ABS resin to being applied to military, automobiles, electronic and electrical appliances.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a flame-retardant ABS masterbatch and a preparation method thereof. Background technique [0002] Existing ABS resin has excellent properties such as high surface hardness, toughness, good low temperature resistance, good creep resistance, good dimensional stability, and small molding shrinkage, so it is used in military industry, automobiles, electronic and electrical components and other fields. Big. At the same time, plastic masterbatch additives can simplify the process, improve the mixing quality and reduce dust flying. However, the oxygen index of ABS resin is only 18.3-2010 (less than 21), which is a flammable material, thus limiting its application. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant ABS masterbatch and a preparation method thereof. [0004] The embodiment of the present invention is realized in thi...
