preparation example Construction

[0042] The present invention also provides a method for preparing said high-damping, low-gloss nylon 6 / ABS alloy material, comprising the following steps:

[0043] After mixing PA6 resin, ABS resin 1, ABS resin 2, polyolefin elastomer, maleic anhydride grafted polyolefin elastomer, compatibilizer, antioxidant and lubricant, put them into a twin-screw extruder, Melt extrusion and granulation to obtain nylon 6 / ABS alloy material with high damping and low gloss.

[0044] Under optimal conditions, the melt extrusion process is: twin-screw extruder barrel temperature 210-240°C, screw speed 300-500r / min, vacuum degree -0.1-0.04MPaMPa.

Embodiment 1

[0050] The preparation method of a kind of high damping, low luster nylon 6 / ABS alloy material is as follows: 40 parts by weight of PA6 resin (M2800), 20 parts by weight of ABS AE8000, 25 parts by weight of ABS PA746, 2 parts by weight of POE 6202, 5 parts by weight of POE - g-MAH (N493D), 8 parts by weight of S601N, 0.2 parts by weight of antioxidant 1098, and 0.6 parts by weight of polyethylene wax were stirred in a high-speed mixer for 1 to 3 minutes to obtain a premix;

[0051] Put the premixed material into an intermeshing parallel co-rotating twin-screw extruder, melt extrude, granulate high-damping, low-gloss nylon 6 / ABS alloy material; wherein, the melt extrusion process is: twin-screw extrusion The barrel temperature of the machine is 240°C, the screw speed is 300r / min, and the vacuum degree is -0.1MPa.

Embodiment 2

[0053] The preparation method of a high-damping, low-gloss nylon 6 / ABS alloy material is as follows: 45 parts by weight of PA6 resin (YH3000), 23 parts by weight of ABS AE8000, 20 parts by weight of ABS 121H, 3 parts by weight of POE 6202, 3 parts by weight of POE- g-MAH (N493D), 6 parts by weight of S601N, 0.4 parts by weight of antioxidant 1098, and 0.4 parts by weight of polysiloxane were stirred in a high-speed mixer for 1 to 3 minutes to obtain a premix;

[0054] Put the premixed material into an intermeshed parallel co-rotating twin-screw extruder, and obtain high damping and low gloss nylon 6 / ABS alloy material through melt extrusion and granulation; wherein, the melt extrusion process is: twin-screw extrusion Exit barrel temperature is 210°C, screw speed is 500r / min, vacuum degree is -0.04MPa.

Abstract

The present invention relates to high-damping, low-gloss nylon 6 / ABS alloy material and a preparation method thereof. The high-damping, low-gloss nylon 6 / ABS alloy material is made of a raw material composition, and the raw material composition includes: PA6 resin 40~ 50 parts by weight, ABS resin 1 20~25 parts by weight, ABS resin 2 15~25 parts by weight, polyolefin elastomer 2~5 parts by weight, maleic anhydride grafted polyolefin elastomer 1~5 parts by weight, compatibilizer 4-8 parts by weight, 0.2-0.6 parts by weight of antioxidant, 0.2-0.6 parts by weight of lubricant, the particle size of the ABS resin 1 is 500-1000 nm, and the particle size of the ABS resin 2 is 100-300 nm. The PA6 / ABS alloy material prepared by the invention has high damping coefficient and excellent noise reduction effect; it also has ultra-low gloss, is non-toxic and environment-friendly, and is beneficial to material recovery; it fills a gap in the market and has extremely high added value.

Description

technical field [0001] The invention relates to the technical field of polymer material blending and modification, in particular to a nylon 6 / ABS alloy material with high damping and low gloss and a preparation method thereof. Background technique [0002] Safety, comfort and energy saving are the future development directions of the automotive field, which puts forward higher requirements for automotive polymer modified materials. In the automotive interior, in addition to requiring the parts to ensure certain mechanical properties, the material must first have a certain matte effect to reduce the driver's visual fatigue and ensure safe driving. There are two main ways to obtain the matte effect of automotive interior parts: first, adding a matting agent; second, spraying a matte paint. Although these two methods can obtain a good matting effect, the matting agent is generally cross-linked resin Gel cannot be melted, which will have a certain impact on the performance of t...
