Functional PE water supply pipe formula and preparation method thereof

Abstract

The invention discloses a functional PE water supply pipe formula and a preparation method thereof. The PE water supply pipe formula consists of an inner layer and an outer layer; the inner layer is prepared from a composite material with the anti-corrosion and antibacterial functions; the composite material is prepared from the following ingredients in parts by weight: 100 parts of high-density PE resin, 0.2 to 1.5 parts of anti-corrosion antibacterial agents, 0.2 to 0.8 part of antioxidants and 0.5 to 2 parts of lubricating agents, the outer layer is prepared from anti-ultraviolet-aging PE modification materials; the double-layer supply and extrusion process is used for the water supply pipe production. The PE water supply pipe provided by the invention has good anti-aging, anti-corrosion and anti-bacterial performance, so that the problem of color change of the conventional water supply pipe in the sunlight for a long time is solved; the service life is prolonged; the bacterium breeding in the pipe is avoided; the guarantee is provided for the drinking water safety of people.

Description

technical field [0001] The invention belongs to the field of development and application of polymer materials, and in particular relates to a functional PE water supply pipe and a preparation method of the material. Background technique [0002] According to the US Centers for Disease Control and Prevention, about 1.7 million Americans are hospitalized for various bacterial infections each year, and about 100,000 people die as a result. Globally, hospitals and public areas of public activities consider adopting all feasible sanitation measures to control the spread of bacteria and viruses, but drug-resistant strains continue to emerge, and 760,000 Americans are still infected with viruses and eating bacteria-contaminated food every year. sick from food. [0003] Legislative departments are improving the hygienic standards of medical services, food processing and other industries. Traditional indoor panel materials and disinfection and sterilization methods have exposed more...

AI Technical Summary

Problems solved by technology

[0006] Existing water supply pipes include cast iron pipes, PVC pipes, PPR pipes, PE pipes, etc. Large-scale water supply pipes are mainly made of PE pipes and cast iron pipes, which have a multi-single-layer structure and have no antibacterial effect. Long-term use will cause bacteria to grow. Bring certain safety hazards to people's health
