Problems solved by technology

Plastic bags are also commonly used to hold domestic garbage. Domestic garbage is prone to breed bacteria due to its high organic content, and it is easy to rot in plastic bags and emit peculiar smells. However, the existing plastic bags do not have good antibacterial and antiseptic properties.

preparation example Construction

[0012] The invention provides a kind of preparation method of antibacterial plastic bag, wherein, described preparation method comprises:

[0013] (1) After uniformly mixing polyethylene, acrylonitrile, butadiene, styrene, coupling agent, stabilizer and surfactant, extruding and granulating to obtain masterbatch M;

[0014] (2) Blending the master batch M with the antibacterial agent, through the film blowing process, to obtain a plastic film, and then cutting the film to make bags to obtain the plastic bag, wherein,

[0015] Relative to 100 parts by weight of polyethylene, the content of the acrylonitrile is 50-75 parts by weight, the content of the butadiene is 15-35 parts by weight, the content of the styrene is 65-80 parts by weight, the The content of the coupling agent is 8-15 parts by weight, the content of the stabilizer is 6-15 parts by weight, and the content of the surfactant is 20-35 parts by weight.

[0016] Through the synergistic effect of the above-mentioned v...

Embodiment 1

[0022] After uniformly mixing polyethylene, acrylonitrile, butadiene, styrene, vinyl silane, benzoic acid and sodium stearate in a weight ratio of 100:55:20:70:10:8:25, extrude Granulating to obtain the master batch M; blending the master batch M with an antibacterial agent, and going through a film blowing process to obtain a plastic film, and then cutting the film to make a bag to obtain the plastic bag A1.

[0023] In the above method, the polyethylene has a weight average molecular weight of 50,000, and the antibacterial agent is composed of metallic copper and aluminum oxide.

Embodiment 2

[0025] After uniformly mixing polyethylene, acrylonitrile, butadiene, styrene, aminosilane, cadmium laurate and magnesium stearate in a weight ratio of 100:65:25:75:12:12:30, extrude Granulating to obtain the master batch M; blending the master batch M with an antibacterial agent, and going through a film blowing process to obtain a plastic film, and then cutting the film to make a bag to obtain the plastic bag A2.

[0026] In the above method, the polyethylene has a weight average molecular weight of 80,000, and the antibacterial agent is composed of metal zinc and silicon dioxide.

Abstract

The invention discloses an antibacterial plastic bag and a preparation method thereof. The preparation method includes the steps that after polyethylene, acrylonitrile, butadiene, styrene, a coupling agent, a stabilizer and a surface active agent are evenly mixed, extrusion pelletizing is conducted, so that a master batch M is obtained; the master batch M and an antibacterial agent are blended, and a plastic film is obtained through the film blowing process; afterwards, the film is cut for bag making, and accordingly the plastic bag is obtained; with respect to 100 weight parts of the polyethylene, the content of the acrylonitrile accounts, by weight, for 50-75 parts, the content of the butadiene accounts, by weight, for 15-35 parts, the content of the styrene accounts, by weight, for 65-80 parts, the content of the coupling agent accounts, by weight, for 8-15 parts, the content of the stabilizer accounts, by weight, for 6-15 parts, and the content of the surface active agent accounts, by weight, for 20-35 parts. The antibacterial plastic bag made through the method has a good antibacterial property and antiseptic property.

Description

technical field [0001] The invention relates to plastic products, in particular to an antibacterial plastic bag and a preparation method thereof. Background technique [0002] Plastic bags are indispensable items in people's daily life. They are often used to hold other items. They are widely used because of their cheapness, light weight, large capacity, and easy storage. Plastic bags are also commonly used to hold household garbage. Domestic garbage is easy to breed bacteria due to its high organic content, and it is easy to rot in plastic bags and emit peculiar smell. However, existing plastic bags do not have good antibacterial and antiseptic properties. Contents of the invention [0003] The object of the present invention is to provide an antibacterial plastic bag and a preparation method thereof. The antibacterial plastic bag prepared by the method has good antibacterial performance and anticorrosion performance. [0004] In order to achieve the above object, the in...
