preparation example Construction

[0029] The present invention also provides a method for preparing an anti-drop flame retardant ABS material, which comprises the following steps:

[0030] a. Weigh each component according to the above mass percentage, specifically, ABS resin: 70-80%; toughening agent: 2-6%; composite flame retardant: 18-25%; antioxidant: 0.2- 0.6%; processing aid: 0.3-1%; anti-dripping agent: 0.1-0.3%, and mix the weighed components in a high-speed mixer and stir for 2-5 minutes;

[0031] b. Add the homogeneously mixed material in step a into the hopper of the twin-screw extruder, melt, blend and extrude through the high-temperature extruder, cool, air-dry, and granulate;

[0032] Among them, the temperature of each heating zone of the twin-screw extruder is respectively set as follows: first zone temperature: 180-190°C; second zone temperature: 185-195°C; third zone temperature: 190-200°C; fourth zone temperature: 200 ~210℃; temperature in zone five: 200~210℃; temperature in zone six: 200~2...

Embodiment 1

[0036] Weigh acrylonitrile-butadiene-styrene copolymer (ABS)--77.3kg, styrene triblock copolymer (SBS)--4kg, composite flame retardant--18kg (bromotriazine--14kg , Sb 2 o 3 --4kg), antioxidant --0.3kg (main antioxidant 1010--0.2kg, secondary antioxidant 168--0.1kg), ethylene bisstearic acid amide (EBS) --0.3kg, containing Polytetrafluoroethylene (PTFE) - 0.1kg.

[0037]Then mix for 3 minutes in a high speed mixer. Then add the mixed material into the hopper of the twin-screw extruder, and control the temperature of each section: Zone 1: 185°C; Zone 2: 185°C; Zone 3: 195°C; Zone 4: 195°C; Zone 5 : 200°C; Sixth zone: 195°C; Seventh zone: 190°C; Eighth zone: 185°C; Machine head temperature: 180°C; Screw speed 400r / min, after melt blending extrusion, water cooling, air drying, pelletizing, drying Dry, and finally packaged into bags to obtain anti-drop flame-retardant ABS material.

Embodiment 2

[0039] Weigh acrylonitrile-butadiene-styrene copolymer (ABS)--74.3kg, styrene triblock copolymer (SBS)--5kg, composite flame retardant--20kg (bromotriazine--15kg , Sb 2 o 3 --5kg), antioxidant --0.3kg (primary antioxidant 1010--0.2kg, secondary antioxidant 168--0.1kg), ethylene bisstearic acid amide (EBS) --0.3kg, containing Polytetrafluoroethylene (PTFE) - 0.1kg.

[0040] Then mix for 3 minutes in a high speed mixer. Then add the mixed material into the hopper of the twin-screw extruder, and control the temperature of each section: Zone 1: 185°C; Zone 2: 185°C; Zone 3: 195°C; Zone 4: 195°C; Zone 5 : 200°C; Sixth zone: 195°C; Seventh zone: 190°C; Eighth zone: 185°C; Machine head temperature: 180°C; Screw speed 400r / min, after melt blending extrusion, water cooling, air drying, pelletizing, drying Dry, and finally packaged into bags to obtain anti-drop flame-retardant ABS material.

Abstract

The invention discloses an anti-dropping flame-retardant ABS material, which comprises the following components by mass: 70-80% of ABS resin; 2-6% of a flexibilizer; 18-25% of a composite flame retardant; 0.2-0.6% of an anti-oxidant; 0.3-1% of a processing additive; and 0.1-0.3% of an anti-dropping agent. The invention also provides the preparation method of the anti-dropping flame-retardant ABS material. The anti-dropping flame-retardant ABS material provided by the invention not only has the advantages of good mechanical properties, high-efficient flame retardance, easy molding processability, and the like, but also has the advantage of no damage after high-altitude drop.

Description

technical field [0001] The invention relates to the technical field of general plastic modification in polymer materials, in particular to a drop-resistant flame-retardant ABS material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is a material with excellent comprehensive properties, with good toughness, dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, molding Processability and other advantages. In order to meet the requirements of flame retardancy of ABS materials, flame retardant modification of ABS materials has been carried out. Flame retardant ABS materials are widely used in office equipment, home appliances and other fields. [0003] At present, for flame-retardant ABS materials at home and abroad, the generally used toughening system is ABS high-glue powder. The finished products made of flame-retardant ABS materials using this toughening system are di...
