Embodiment 1

[0030] (1) Weigh the raw materials of each component according to the following parts by weight:

[0031]

[0032] Wherein the flame retardant is bromotriazine and antimony trioxide, and its weight ratio is 3:1;

[0033] (2) The above raw materials are mixed at high speed by a high-speed mixer, the speed of the high-speed mixer is controlled to 700rmp, the mixing temperature is 80°C, and the mixture is mixed for 3 minutes; the mixed material is passed through a twin-screw extruder, and the temperature of each zone is controlled at 190 ABS / PET weather-resistant and flame-retardant material can be obtained by extruding strands and pelletizing at -250°C. The mechanical properties of the test are shown in Table 1.

Embodiment 2

[0035] (1) Weigh the raw materials of each component according to the following parts by weight:

[0036]

[0037]

[0038] (2) Mix the above raw materials at a high speed with a high-speed mixer, control the speed of the high-speed mixer to 700rmp, mix the temperature at 60°C, and mix for 6 minutes; pass the mixed material through a twin-screw extruder, and the temperature of each zone is controlled. At 195-260°C, the weather-resistant and flame-retardant ABS / PET material can be obtained by pelletizing the strands. The mechanical performance test is shown in Table 1.

Embodiment 3

[0040] (1) Weigh the raw materials of each component according to the following parts by weight:

[0041]

[0042] (2) The above-mentioned raw materials are mixed at high speed by a high-speed mixer, the speed of the high-speed mixer is 700rmp, the mixing temperature is 60°C, and mixed for 5 minutes; the mixed material is passed through a twin-screw extruder, and the temperature of each zone is controlled at 220 -265°C, the weather-resistant and flame-retardant ABS / PET material can be obtained by cutting the strands into pellets.

Abstract

The invention belongs to the technical field of polymer materials, and relates to an ABS / PET material and a preparation method thereof. The material is made of the following components by weight: 100 parts of ABS resin, 10-50 parts of PET resin, 20-60 parts of glass fiber, 12-30 parts of flame retardant, 5-15 parts of compatibilizer, light stable 0.2-1.0 parts of lubricant, 0.2-1.5 parts of lubricant, 0.4-1.2 parts of antioxidant. The weather-resistant and flame-retardant ABS / PET material for extrusion prepared by the present invention has excellent extrusion formability, outstanding flame retardancy and weather resistance, can meet the needs of outdoor use, and greatly expands the application range of ABS materials , Oil resistance, solvent resistance and physical and mechanical properties are significantly better than unmodified ABS materials, and the extruded products have excellent performance. It can be widely used in various fields of social life such as pipelines, building profiles and panels, and has great economic and social value.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an ABS / PET material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) is widely used in various fields of social life because of its excellent mechanical properties, dimensional stability, easy processing, coloring, and convenient post-processing. One of the wide range of polymers. At the same time, ABS has the advantages of high melt strength and good extrusion performance. But at the same time, ABS plastic also has disadvantages such as low heat distortion temperature, poor chemical resistance, especially oil resistance, and poor weather resistance, which limit its application. [0003] Polyethylene terephthalate (PET) has the advantages of non-toxicity, weather resistance, good stability against chemicals, high mechanical strength, outstanding oil and solvent resistance, and is cheap, but due to low viscosity and lo...
