specific Embodiment approach

[0014] The present invention proposes a kind of antibacterial polypropylene material, and its component and content are:

[0015] 100 parts of polypropylene (PP) resin;

[0016] Filling agent 25-35 parts;

[0017] Toughening agent 5-15 parts;

[0018] 0.2-0.8 parts of antibacterial agent;

[0019] Dispersant 0.5~1.5 parts;

[0020] Antioxidant 0.1~0.5 parts;

[0021] UV absorber 0.1~0.5 part;

[0022] The above contents are by weight.

[0023] The polypropylene resin is homopolypropylene.

[0024] The antibacterial agent is compounded by nano-silver and organic silicon antibacterial agent in a mass ratio of 5:1.

[0025] The filler is nanometer calcium carbonate.

[0026] The toughening agent is polyolefin elastomer ethylene-1-octene copolymer (POE), which is 8150 type POE produced by DuPont Company of the United States.

[0027] The dispersant is TAS-2A, an ethylene bis fatty acid amide high-gloss lubricating dispersant.

[0028] The antioxidant is phosphite antioxi...

Embodiment 1

[0038] In parts by weight, mix 100 parts of PP resin, 25 parts of filler, 5 parts of toughening agent, 0.2 part of antibacterial agent, 0.5 part of dispersant, 0.1 part of antioxidant, and 0.1 part of ultraviolet absorber in a high-speed mixer 3 to 5 minutes, the speed of the high-speed mixer is 800 rpm; then the mixed raw materials are placed in a parallel twin-screw extruder for melt extrusion and granulation. The extrusion process is: 1 zone 170--180 ℃ , Zone 2 180--190°C, Zone 3 180--190°C, Zone 4 175--185°C, screw speed 300-350r / min, feeding frequency 15-20Hz, melt pressure 3.0-4.0MPa, vacuum degree -0.03---0.06MPa.

Embodiment 2

[0040] In parts by weight, 100 parts of PP resin, 30 parts of filler, 10 parts of toughening agent, 0.5 part of antibacterial agent, 1 part of dispersant, 0.3 part of antioxidant, 0.3 part of ultraviolet absorber, mixed in a high-speed mixer 3 to 5 minutes, the speed of the high-speed mixer is 800 rpm; then the mixed raw materials are placed in a parallel twin-screw extruder for melt extrusion and granulation. The extrusion process is: 1 zone 170--180 ℃ , Zone 2 180--190°C, Zone 3 180--190°C, Zone 4 175--185°C, screw speed 300-350r / min, feeding frequency 15-20Hz, melt pressure 3.0-4.0MPa, vacuum degree -0.03---0.06MPa.

Abstract

The antibacterial polypropylene material consists of polypropylene resin 100 weight portions, stuffing 25-35 weight portions, toughening agent 5-15 weight portions, antiseptic 0.2-0.8 weight portion, dispersant 0.5-1.5 weight portions, antioxidant 0.1-0.5 weight portion and ultraviolet absorber 0.1-0.5 weight portion. The polypropylene resin is homopolypropylene, and the antiseptic is compounded with nanometer silver and organosilicon antiseptic. The present invention also provides the preparation process of the antibacterial polypropylene material with low production cost, excellent antiseptic performance.

Description

technical field [0001] The invention relates to an antibacterial polypropylene material and a preparation method thereof, in particular to an antibacterial and durable polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the five general-purpose plastics with a density of 0.90g / cm 3 , is the second lightest polymer material in existing resins (only larger than polymethylpentene, with a density of 0.85g / cm 3 ). [0003] In people's daily life, polypropylene plastic products are widely used: such as kitchen utensils, toilet facilities, trash cans, plastic shells of household appliances, wallpapers, food packaging bags, etc. Due to the appropriate temperature and humidity, it is very easy to be infected with bacteria. Therefore, it is extremely necessary to develop an antibacterial polypropylene material. [0004] At present, there are mainly two methods of making antibacterial polypropylene materials: filling t...
