Antibacterial pipe and preparation method thereof

Abstract

The invention provides an antibacterial pipe and a preparation method thereof. The antibacterial pipe comprises an inner layer, a middle layer and an outer layer; the inner layer comprises polypropylene resin, linear low-density polyethylene resin, modified tetrapod-like zinc oxide whiskers, chitosan, an antioxidant and a dispersing agent; the modified tetrapod-like zinc oxide whiskers are gamma-aminopropyltriethoxysilane surface modified tetrapod-like zinc oxide whiskers, the weight of the modified tetrapod-like zinc oxide whiskers account for 0.0080%-0.070% of the weight of the inner layer,and the weight of the chitosan accounts for 0.085%-0.42% of the weight of the inner layer; the middle layer comprises polypropylene resin, basalt fibers, a compatilizer, a lubricant and an antioxidant, and the basalt fibers account for 15.0%-23.0% of the weight of the middle layer; and the outer layer comprises polypropylene resin and color master batch. The antibacterial pipe is good in mechanical property and excellent in antibacterial and bacteriostatic effect, the used materials are environmentally friendly and free of heavy metal residues, the antibacterial pipe can be directly degraded in the environment after being discarded, no harm is caused, and the antibacterial pipe is a genuine green and environment-friendly material.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to an antibacterial pipe and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for water quality sanitation and water safety are getting higher and higher, and the national level is also advocating a green, environmentally friendly and healthy lifestyle. [0003] Since domestic water is generally tap water, the water often contains bacteria such as Escherichia coli and Staphylococcus aureus, which will endanger people's health; existing pipes are usually removed by adding silver ion antibacterial agents to the inner layer of the pipe. To achieve antibacterial and antibacterial effects, although the antibacterial and antibacterial effects of silver ion antibacterial agents are very good, silver ions are heavy metals after all. Drinking water containing silver ions for a long time may cause silver ions to d...

Problems solved by technology

[0003] Since domestic water is generally tap water, the water often contains bacteria such as Escherichia coli and Staphylococcus aureus, which will endanger people's health; existing pipes are usually removed by adding silver ion antibacterial agents to the inner layer of the pipe. To achieve antibacterial and antibacterial effects, although the antibacterial and antibacterial effects of silver ion antibacterial agents are very good, silver ions are heavy metals after all. Drinking water containing silver ions for a long time may cause silver ions to deposit in the human body and easily cause chronic poisoning , but endanger people's health

Moreover, the existing antibacterial pipes have poor mechanical properties
