High and low temperature resistance antibacterial tube for conveying domestic drinking water and preparation method of high and low temperature resistance antibacterial tube

Abstract

The invention provides a high and low temperature resistance antibacterial tube for conveying domestic drinking water. As the inner and outer layers are mainly made of a same polypropylene raw material, the phenomenon that a composite tube is destroyed due to department can be prevented; the outer layer is white, and the inner layer is ash blond, thus the self light transmittance of a PP-R tube is effectively improved under the condition of keeping white appearance and the self toughness of plastic, and bacteria are prevented from breeding; the material of the inner layer contains a high-temperature material so as to enable a product not to be liable in deforming and breaking at high and low temperatures; and the material of the inner layer contains mineral powder, and the mineral powder contains tourmaline powder which is a polar crystalline solid with a special structure, thus the material of the inner layer can release electric ions self for a long time and also release air anions and far infrared rays permanently. Therefore, when a water source accesses the product, by virtue of the anions and the infrared rays released by the material of the inner layer, residual chlorine in water can be eliminated, breeding of harmful bacteria is inhibited, organic compounds, inorganic compounds and heavy metal pollution are purified, water molecular motion is accelerated, and the content of mineral substances in water is also increased.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high and low temperature resistant antibacterial pipe for domestic drinking water delivery and a preparation method thereof. Background technique [0002] About 50% of China's water sources are polluted; Pollutants: There are hundreds of organic compounds and heavy metal ions entering the water source (for micro-pollution dominated by organic pollution, such as: pesticides, environmental endocrine disruptors, algae toxins and heavy metal pollutants, etc. It cannot be completely removed; and there are excessive levels of fluorine, arsenic, iron, manganese, etc.). [0003] The tap water treatment process mainly targets bacteria and viruses in the water, while organic and inorganic compounds and heavy metals cannot be removed, and there are still very few residual microorganisms in the water, and the residual microorganisms will naturally and rapidly reproduce some bacteria.

Problems solved by technology

The all-plastic pipe not only adds a large amount of antioxidants to prevent material degradation, but the antioxidants are extracted into the stagnant water in the pipes, which is likely to cause water pollution, and because there is no light-proof and oxygen-blocking material in the all-plastic pipes, it is easy to breed microorganisms lead to secondary pollution of water quality

In addition, PP-R pipes are translucent or semi-transparent, and bacteria are easy to breed when light is transmitted.
