Embodiment 1

[0020] An antibacterial and mite-repelling plastic masterbatch and a preparation method thereof, comprising the following steps:

[0021] (1) Mix 90 parts of polyethylene, 3 parts of dimethylpropane carboxylate, 20 parts of chitin, 0.5 part of stearate, and 2 parts of bis(2-ethylhexyl)phthalate.

[0022] (2) Granulate through a twin-screw extruder, wherein the temperatures in zone 1-5 are 150°C, 175°C, 180°C, 190°C, 190°C respectively, the head temperature is 180°C, and the rotation speed is 40r / min.

[0023] The polyethylene plastic masterbatch prepared in this implementation case has a measured mite repelling efficiency of 96%, and has a broad-spectrum antibacterial effect.

Embodiment 2

[0025] An antibacterial and mite-repelling plastic masterbatch and a preparation method thereof, comprising the following steps:

[0026] (3) Mix 100 parts of polyethylene, 5 parts of dimethylpropane carboxylate, 10 parts of chitin, 0.6 parts of stearate, and 4 parts of bis(2-ethylhexyl)phthalate.

[0027] (4) Granulate through a twin-screw extruder, wherein the temperatures in Zones 1-5 are 150°C, 175°C, 180°C, 190°C, and 190°C, respectively, the head temperature is 180°C, and the rotation speed is 45r / min.

[0028] The polyethylene plastic masterbatch prepared in this implementation case has a measured mite repelling efficiency of 97%, and has a broad-spectrum antibacterial effect.

Embodiment 3

[0030] An antibacterial and mite-repelling plastic masterbatch and a preparation method thereof, comprising the following steps:

[0031] (5) Mix 100 parts of polyethylene, 6 parts of dimethylpropane carboxylate, 30 parts of chitin, 0.8 parts of paraffin, and 6 parts of bis(2-ethylhexyl)phthalate.

[0032] (6) Granulate through a twin-screw extruder, wherein the temperatures in Zones 1-5 are 150°C, 175°C, 180°C, 190°C, and 190°C, respectively, the head temperature is 180°C, and the rotation speed is 50r / min.

[0033] The polyethylene plastic masterbatch prepared in this implementation case has a measured mite repelling efficiency of 97%, and has a broad-spectrum antibacterial effect.

Abstract

The invention discloses an antibacterial anti-mite plastic masterbatch and a preparation method thereof. The preparation method of the antibacterial anti-mite plastic masterbatch comprises the following steps: performing uniform mixing on 90-110 parts by mass of polyethylene, 3-8 parts by mass of dimethylpropane carboxylate, 10-30 parts of chitin, 0.5-1 part by mass of a lubricant and 2-8 parts bymass of a plasticizer, and performing extrusion granulation by using a twin-screw extruder. The plastic masterbatch prepared by the method provided by the invention has a remarkable effect of repelling mites, a broad-spectrum antibacterial effect, a simple production process and a wide scope of application.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial and mite-repelling plastic masterbatch and a preparation method thereof. Background technique [0002] Mites are tiny pests that are not easy to see with the naked eye, and can usually be divided into several categories such as dust mites, acaroid mites, and gamata mites. Mites are widely distributed in dark corners of the room, carpets, mattresses, pillows, air conditioners, etc., among which dust mites are the most widely distributed. The corpses, secretions and excreta of mites are allergens, which may cause allergic dermatitis, asthma, bronchitis, allergic rhinitis and other diseases, endanger human health and affect people's quality of life. [0003] Existing methods for removing mites include exposure to sunlight, irradiation with mite removing lamps, and acaricides. Among them, the former two kill mites by ultraviolet rays. Studies have shown that mites...
