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] Each component content (percentage by weight) of jellyfish grain of table 1

[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 ABS8434, the compatibilizer PP-g-MAH is selected from ST-9 of Nanjing Plastic 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, antibacterial ABS composition and a preparation method thereof, comprising the following components: ABS resin: 50.4-97.4%; modifier: 0-40%; compatibilizer: 1-3% ; Antibacterial agent: 0.5-2%; jellyfish granule 1-5%; auxiliary agent 0.1-3%; the preparation method is to mix ABS resin, modifier, compatibilizer, antibacterial agent and auxiliary agent in a high mixer 1-3min; mix evenly, place in the main feeding port of the twin-screw extruder, add jellyfish pellets from the side feeding port, melt and extrude, granulate and dry, and the product is ready. The invention uses jellyfish granules with high-melt foaming PP as the carrier as the air stripping agent, which can effectively remove various volatile small molecules and organic compounds produced in the processing process. After adding the antibacterial agent, the antibacterial ability of the material is significantly increased. The prepared ABS composition not only has the characteristics of low odor and low emission, but also has excellent antibacterial 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...
