Embodiment

[0020] Raw material: Polypropylene resin (Borealis)

[0021] Inorganic nano antibacterial agent (made from commercially available products as raw materials)

[0022] Titanate coupling agent NDZ-1, low molecular weight polyethylene wax

[0023] Manufacturing process:

[0024] (1) Powder preparation:

[0025] 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;

Abstract

The invention relates to an inorganic nano antibacterial polypropylene water-feeding pipe, wherein the pipes is composed of modified polypropylene with charged inorganic nano antimicrobial agent. The pipes can be used for cold and hot water pipeline system in construction, The material can eradicate several dozens of bacterial in the water supply pipe, such as bacteria, fungus, mildew.

Description

Technical field: [0001] The invention relates to a new type of water supply pipe material for building, and in particular provides an inorganic nanometer antibacterial polypropylene water supply pipe material 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. Seriously rusted. In order to 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 ...
