Embodiment Construction

[0018] A nano antibacterial polypropylene pipe mainly consists of polypropylene, an inorganic antibacterial agent and a processing aid, and the percentage by weight of each component of the pipe is:

[0019] Polypropylene resin: 93% to 99%;

[0020] Inorganic nano antibacterial agent: 0.2~3%;

[0021] Antioxidants and anti-ultraviolet absorbers: 0.8 to 4%.

[0022] Concrete preparation process is as follows:

[0023] (1) Preparation of masterbatch:

[0024] First, add 1.0% coupling agent NDZ-1 and 0.5% low molecular weight polyethylene wax into the inorganic nano antibacterial agent according to the percentage of the total weight of the inorganic nano antibacterial agent; Stir 60 times per minute for 1.5-2 minutes for impregnation; dry the mixed powder after impregnation at 90-120°C for 90-100 minutes;

[0025] According to the total weight percentage of inorganic nano antibacterial powder, 19% antibacterial active powder and 1% polyethylene wax and 80% polypropylene resin...

Abstract

The invention discloses a nano antibacterial polypropylene pipe and a preparation method of the same, and relates to the technical field of water supply pipes for building. The pipe mainly comprises polypropylene, an inorganic antibacterial agent and a processing aid. The pipe comprises the following components by weight percent: 93-99% of polypropylene resin, 0.2%-3% of inorganic nano antibacterial agent and 0.8%-4% of processing aid. The nano antibacterial polypropylene pipe is simple in processing technology and easy to produce, and needs no special equipment. Besides having the advantages of being strong in corrosion resistance, easy for hot-melt conjunction, cheap and hard, of the normal polypropylene water supply pipes, the nano antibacterial polypropylene pipe also can kill dozens of strains, such as the bacteria, the fungus and the mycete, in the water supply pipes, especially, has a remarkable antibacterial effect on the bacteria, such as escherichia coli, staphylococcus aureus and Candida albicans, has a long antibacterial effect, can be widely used in cold-hot water pipe systems for building, and can meet the requirements of people on antibacterial performance of the water supply pipes in daily life, thereby having great potential social benefit and economic benefit.

Description

technical field [0001] The invention relates to the technical field of water supply pipes for buildings, in particular to a nano antibacterial polypropylene pipe and a preparation method thereof. Background technique [0002] Galvanized steel pipes have been used for hot and cold water in buildings for nearly a hundred years. According to most water quality monitoring data, the main reason for the deterioration of tap water "red water" and "black water" is the failure of water supply pipes in buildings. The corrosion is serious. In order to improve the water quality and ensure the quality of water supply, the Ministry of Construction has stipulated that since June 1, 2000, the use of galvanized steel pipes in building water supply projects is prohibited. There are plastic pipes, plastic-metal composite pipes, etc. that can be replaced. Among them, polypropylene pipe has the advantages of strong corrosion resistance, easy bonding, low price, and hard texture, and is one of t...
