preparation example Construction

[0050] Preparation of jellyfish pellets:

[0051] Fully mix high-melt-strength polypropylene with different melt strengths and mineral fillers (talc powder, calcium carbonate or barium sulfate) according to the ratio shown in Table 1, extrude strip-shaped polypropylene in an 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.

[0052] Table 1 The content of each component of jellyfish pellets (weight percent)

[0053]

Embodiment 1

[0055] A kind of low odor, low emission, antibacterial ABS composition, its raw material formula is as shown in table 3, and its preparation method comprises the following steps:

[0056] 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.

[0057] 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

[0059] A kind of low odor, low emission, antibacterial ABS composition, its raw material formula is as shown in table 3, and its preparation method is with embodiment 1:

[0060] Among them, the ABS resin is selected from Takahashi's ABS 8434, 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, low-emission anti-bacterial ABS composition and a preparation method thereof. The composition comprises the following components: 50.4-97.4 percent of ABS resin, 0-40 percent of a modifying agent, 1-3 percent of a compatilizer, 0.5-2 percent of an antibacterial agent, 1-5 percent of medusa grains, and 0.1-3 percent of an additive. The method comprises the following steps: mixing the ABS resin, the modifying agent, the compatilizer, the antibacterial agent and the additive in a high mixing machine for 1-3 minutes; uniformly mixing, placing in a main feed inlet of a double-screw extruder, adding the medusa grains from a lateral feed inlet, and performing melt extrusion, pelletization and drying, thereby obtaining the ABS composition. According to the invention, the medusa grains taking HMSPP as a carrier are adopted as an air lift agent, various volatiled small molecules and organic compounds generated during the manufacturing process can be removed; with the antibacterial agent added, the anti-bacterial capability of materials can be greatly improved. The prepared ABS composition has low odor, low emission, and an excellent anti-bacterial effect.

Description

technical field [0001] The invention relates to an ABS composition, in particular to a low-odor, low-emission, antibacterial 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. ABS resin has good mechanical properties and excellent molding processing characteristics, and has also been widely used in the automotive industry. Such as door panels, dashboards, sub-dashboards, and sun visors in automotive interiors. The volatile gas contained in interior materials is the main source of new car smell, so it is necessary to control the gas volatilization of automotive interior part...
