Embodiment 1

[0025] According to parts by weight, 89.9 parts of polypropylene, 3 parts of KAlSi 3 o 8 , 5 parts of vinyl elastomer (POE), 0.2 parts of tetrakis [β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, 0.3 parts of tris[2,4-di-tert-butyl Base phenyl] phosphite, 1.2 parts of silicone powder and 0.4 parts of polypropylene grafted maleic anhydride were added to the high mixer and dry mixed for 8 minutes, and then the uniform mixture was added to the twin-screw extruder for melt extrusion and granulation , to obtain an antibacterial polypropylene material, wherein the temperature of the first zone of the twin-screw extruder is 170°C, the second zone is 175°C, the third zone is 205°C, the fourth zone is 205°C, and the fifth zone is 195°C.

Embodiment 2

[0027] According to parts by weight, 90.5 parts of polypropylene, 4 parts of NaAlSi 3 o 8 , 5 parts of ethylene-propylene-diene rubber (EPDM), 0.3 parts of tetrakis [β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, 0.4 parts of three [2,4-di-tert Butylphenyl] phosphite, 1.3 parts of calcium stearate and 0.5 parts of silane coupling agent are added to the high mixer and dry mixed for 6 minutes, and then the uniform mixture is added to the twin-screw extruder to melt and extrude to granulate. An antibacterial polypropylene material was prepared, wherein the temperature of the first zone of the twin-screw extruder was 170°C, that of the second zone was 170°C, that of the third zone was 205°C, that of the fourth zone was 200°C, and that of the fifth zone was 195°C.

Embodiment 3

[0029] According to parts by weight, 87.2 parts of polypropylene, 2.5 parts of CaAl 2 Si 2 o 8 , 4 parts of styrene-butadiene elastomer (SBS) and 4 parts of styrene-butadiene-styrene elastomer (SEBS), 0.2 parts of tetrakis[β-(3,5-di-tert-butyl-4- Add 0.4 parts of tris[2,4-di-tert-butylphenyl] phosphite, 1.4 parts of zinc stearate and 0.3 parts of titanate coupling agent into the high mixer and dry After mixing for 7 minutes, put the uniform mixed material into the twin-screw extruder to melt and extrude to obtain antibacterial polypropylene material. Zone 205°C, Zone 4 200°C, Zone 5 195°C.

Abstract

The invention discloses an antibacterial polypropylene material and a preparation method thereof. The antibacterial polypropylene material is prepared from 82-96.4 parts by weight of polypropylene, 2-5 parts by weight of an inorganic antibacterial agent, 0-10 parts by weight of a flexibilizer, 0.4-0.9 part by weight of an antioxidant, 1-1.5 parts by weight of a lubricant and 0.2-0.6 part by weight of a coupling agent, and the inorganic antibacterial agent is a feldspar inorganic mineral. The antibacterial polypropylene disclosed by the invention is excellent in antibacterial property, green and environment-friendly, and can realize long-acting antibacterial property.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antibacterial polypropylene material and a preparation method thereof. Background technique [0002] As one of the most common general-purpose engineering plastics, polypropylene is widely used in automobiles, electronic appliances, daily consumables, and packaging materials due to its good mechanical properties, aging resistance, and low price. With the development of the plastic industry, plastic products have become an indispensable product in people's life and industrial production. However, when the objective conditions such as temperature and humidity are suitable, harmful microorganisms such as bacteria and mold will breed on plastic products, seriously endangering the human body. Human health, even life-threatening. [0003] The demand for antibacterial polypropylene is also increasing. Since polypropylene itself has no antibacterial properties, antibacter...
