Problems solved by technology

However, using this formula will affect the toughness of the material and limit the color of the product
[0006] The above-mentioned method solves the odor problem of the material to varying degrees. However, the above-mentioned method is only aimed at the influence of a certain component on the odor, thereby adding an adsorbent to Reduces odor, but in fact material odor is the result of the interaction of multiple component odors

preparation example Construction

[0038] Preparation of jellyfish pellets:

[0039] High melt strength polypropylene with different melt strength and mineral filler (talcum powder, calcium carbonate or barium sulfate) are fully mixed according to the proportion shown in Table 1, extruded strip polypropylene in the extruder, and then Shred it into polypropylene pre-expanded granules; use water as a foaming agent to foam the polypropylene pre-expanded granules to prepare expanded polypropylene with high melt strength; Polypropylene and water were mixed in a high-speed mixer for 5-10 minutes. By controlling the mixing time, jellyfish particles with the water content shown in Table 1 were prepared and released for use.

[0040] Each component content (weight percent) of table 1 jellyfish grain

[0041]

Embodiment 1

[0043] A low odor, low emission ABS composition, its raw material formula is as shown in table 3, and its preparation method may further comprise the steps:

[0044] Weigh each component according to the weight percentage, mix in the high mixer for 1-3min; mix evenly to obtain the premix; put the premix in the main feeding port of the twin-screw extruder, Add jellyfish pellets, melt extrude, then granulate and cool to obtain ABS composition. Determination of its odor and volatile content, the specific data are listed in Table 4.

[0045] Among them, the ABS resin is selected from 121H of LG Chem, and the compatibilizer PP-g-MAH is selected from ST-9 of Nanjing Sutai Polymer Technology Co., Ltd.

Embodiment 2

[0047] A low smell, low emission ABS composition, its raw material formula is as shown in table 3, and its preparation method is with embodiment 1:

[0048] Among them, the ABS resin is selected from Takahashi's ABS8434, the compatibilizer PP-g-MAH is selected from ST-9 of Nanjing Plastic Technology Polymer Technology Co., Ltd., and the modifier is a maleimide heat-resistant modifier. MS-NB selected from DENKA.

Abstract

The invention discloses a low-odor and low-emission acrylonitrile-butadiene-styrene (ABS) composition and a preparation method thereof. The low-odor and low-emission ABS composition comprises the components by weight percent: 52.4-97.4% of ABS resin, 0-40% of a modifier, 1-3% of a compatilizer, 1-5% of water master batch and 0.1-3% of an assistant. The preparation method comprises the following steps: mixing the ABS resin, the modifier, the compatilizer and the assistant in a high mixing machine for 1-3 minutes; evenly mixing; putting into a main feeding hole of a twin-screw extruder; adding the water master batch from a lateral feeding hole; fusing and extruding; pelleting and drying, so as to obtain the low-odor and low-emission ABS composition. By using a maleic anhydride grafted copolymer, the compatibility of the composite material can be greatly improved, the water master batch taking high-melt foaming polypropylene (PP) as a carrier is adopted as a gas stripping agent, kinds of volatile small molecules and organic compounds generated in the processing process can be effectively removed, and the prepared ABS composition has the characteristics of low odor and low emission, and can meet the requirements of automotive interior parts.

Description

technical field [0001] The invention relates to an ABS composition, in particular to a low-odor, low-emission ABS composition and a preparation method thereof. Background technique [0002] Styrene-butadiene-acrylonitrile (ABS) resin combines the rigidity and heat resistance of acrylonitrile, the gloss and processability of polystyrene, and the impact resistance of polybutadiene, and is widely used in household Electrical appliances, office equipment, instrumentation, transportation, building materials, daily appliances and packaging materials and other fields. However, because ABS has a certain volatility at high temperature, commonly used ABS products often produce some volatiles during the processing and molding process, and the volatiles accumulate and adhere to the surface of the product, affecting the appearance and use of the product. Therefore, in the process of processing, it is often necessary to stop production to clean the mold, thereby reducing production effic...
