Problems solved by technology

[0002] Polyacrylonitrile-butadiene-styrene (ABS) is a thermoplastic polymer material with good corrosion resistance, rigidity and transparency. It is currently widely used in the production of cosmetic packaging containers, but it also has poor impact resistance and low temperature Defects such as becoming brittle and aging easily lead to poor comprehensive physical and mechanical properties of the existing packaging containers made of ABS, which cannot meet the increasing market demand

Embodiment 1

[0026] A modified ABS material, by mass percentage, its preparation raw materials include the following components: 50% ABS resin, 16.1% ASA resin, 10.7% ultra-high molecular weight polyethylene, 13.2% styrene, 3.5% poly Phenyl ether, 4% styrene grafted maleic anhydride copolymer, 2.5% ethylene bis-stearamide.

[0027] A method for preparing modified ABS material includes the following steps:

[0028] (1) Vacuum dry the ABS resin and ASA resin at 80°C for 8 hours; dry the polyphenylene ether in vacuum at 120°C for 3 hours;

[0029] (2) Add ultra-high molecular weight polyethylene and xylene at a mass ratio of 1:9 into a vacuum reactor and mix them evenly, and then swell at 100°C for 30 minutes to obtain an ultra-high molecular weight polyethylene initial swelling liquid;

[0030] (3) Add excess ethanol to the initial swelling liquid of ultra-high molecular weight polyethylene and filter to obtain the initial swelling ultra-high molecular weight polyethylene, and then add ethylene bis-...

Embodiment 2

[0035] A modified ABS material, in terms of mass percentage, its preparation raw materials include the following components: 63% ABS resin, 10.3% ASA resin, 6% ultra-high molecular weight polyethylene, 11% styrene, 1.7% poly Phenyl ether, 7% styrene grafted maleic anhydride copolymer, 1% ethylene bis-stearamide.

[0036] A method for preparing a modified ABS material, according to the above formula and using the preparation method in Example 1 to prepare a modified ABS material. The difference is that the extrusion temperature of the twin-screw extruder is 205°C.

Embodiment 3

[0038] A modified ABS material, in terms of mass percentage, its preparation raw materials include the following components: 70% ABS resin, 8% ASA resin, 8.5% ultra-high molecular weight polyethylene, 7% styrene, 2% poly Phenyl ether, 3% styrene grafted maleic anhydride copolymer, 1.5% ethylene bis-stearamide.

[0039] A method for preparing a modified ABS material, according to the above formula and using the preparation method in Example 1 to prepare a modified ABS material. The difference is that the extrusion temperature of the twin-screw extruder is 215°C.

Abstract

The invention discloses a modified ABS material and a preparation method thereof. The material is prepared from the following raw materials in percentage by mass: 50-70% of ABS resin, 8-21% of ASA resin, 5-13% of ultrahigh-molecular-weight polyethylene, 6-15% of styrene, 1-5% of polyphenyl ether, 3-7% of a styrene grafted maleic anhydride copolymer and 0.8-2.5% of ethylene bis stearamide. The ABSmodified material prepared by the method has the advantages of high impact resistance, favorable aging resistance, favorable adhesiveness with paint, wear resistance, corrosion resistance and the like, endows ABS with higher economic value, and satisfies the high requirements for manufacturing high-performance materials.

Description

Technical field [0001] The invention relates to the field of polymer technology, in particular to a modified ABS material and a preparation method thereof. Background technique [0002] Polyacrylonitrile-butadiene-styrene (ABS) is a thermoplastic polymer material with good corrosion resistance, rigidity and transparency. It is currently widely used in the production of cosmetic packaging containers, but it also has poor impact resistance and low temperature Defects such as time becoming brittle and easy to aging have resulted in poor comprehensive physical and mechanical properties of the existing packaging containers made of ABS as raw materials, which cannot meet the increasing market demand. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, to provide a modified ABS material and a preparation method thereof, and then can be prepared with high impact resistance, good aging resistance, good adh...
