Abstract

The invention belongs to the technical field of water supply pipe materials, and in particular relates to a three-layer co-extruded antibacterial PP‑R water supply pipe and a preparation method thereof. The water supply pipe utilizes the synergistic effect of anti-shock agent, anti-bacterial agent and the thickness ratio of each layer. Under specific proportioning conditions, it can achieve 99% anti-bacterial performance and good impact stability, and reduce the precipitation of inorganic ions in the anti-bacterial agent. Improve the impact resistance, solve the problem of the reduction of mechanical properties existing in the addition of inorganic antibacterial agents; at the same time, the total thickness of the prepared antibacterial inner layer and the middle anti-impact layer of the water supply pipe is small, which can significantly reduce the manufacturing cost of the water supply pipe. Huge economic benefits.
