Problems solved by technology

Some large cities in the country have begun to build pipeline direct drinking water (water cups) projects for quality water supply, but only separating drinking water and domestic water with pipelines is far from being able to solve the problem of water pollution. The growth of bacteria on the pipe wall causes secondary pollution of water quality

Abstract

The invention discloses a nano antibacterial plastic tube and a preparation process thereof. The nano antibacterial plastic tube includes a plastic outer layer and a plastic inner layer made of ordinary thermoplastics, and the plastic inner layer is made of 5-10 parts by weight Antibacterial plastics made of nano-scale antibacterial masterbatch and 90-95 parts by weight of ordinary thermoplastics are produced using a double-layer co-extruded composite mold, so that the inner layer of antibacterial plastics is closely bonded to the outer layer of ordinary plastics, shaped like One. Since the inner layer of the present invention is an antibacterial layer added with nano-scale antibacterial materials, it has a killing effect on bacteria in water and can inhibit the growth of bacteria, so this product can keep the water clean and hygienic, and can be applied to water supply by quality Pipeline direct drinking water projects and water supply occasions with high hygienic performance requirements meet people's continuously improving living requirements, and the invention only adds antibacterial materials to the inner plastic, which has the advantage of low cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, relates to an antibacterial plastic pipe, and also relates to a preparation process of the antibacterial plastic pipe. Background technique [0002] The plastic pipes used in water supply and drainage of buildings are generally ordinary plastic pipes such as polypropylene pipes (PP-B, PP-R, PP-H), high-density polyethylene pipes, etc. Although these ordinary plastic pipes can achieve hygiene and health and Requirements, but the bacteria existing in the water quality can neither inhibit their growth nor kill them, and after long-term use, the inner surface of the pipe will adhere to and breed microorganisms. When the water flow in the pipe is slow or the water remains temporarily, the bacteria will adhere to the pipe wall and after a period of reproduction, a layer of bacteria film will be formed, which will reduce the water quality. A special kind of bacteria will grow in the hot wate...
