Abstract

The invention provides an antibacterial heat-insulating master batch for a PPR pipe, and a preparation method thereof, and belongs to the technical field of polymer synthesis modification and processing. The preparation method comprises the following steps: activating glass micro-beads by a coupling agent; kneading with an antibacterial agent, a dispersing agent, a lubricating agent and linear low-density polyethylene; crushing; mixing with an antioxidant, an anti-UV auxiliary agent and PPR resin; and extruding through an extruder, cooling, drying, and pelletizing to obtain master batch with double functions of heat insulation and antibiosis. With the direct application of the master batch to prepare a PPR pipe, the obtained PPR pipe has excellent mechanical property and high yield while having excellent double functions of antibiosis and heat insulation.

Description

Technical field [0001] The invention belongs to the technical field of polymer synthesis modification and processing, and specifically relates to an antibacterial and heat-insulating master batch for PPR pipes and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, the demand for multifunctional PPR (random polypropylene) pipes continues to increase. At the same time, the concept of healthy water continues to gain popularity, and the market for antibacterial tube products is also expanding. However, the current antibacterial masterbatches used for PPR pipes only have a single antibacterial function. To produce composite functional PPR pipes, different functional masterbatches must be used, resulting in low production efficiency. The present invention develops an antibacterial and heat-insulating multifunctional masterbatch suitable for PPR pipes by studying the technological formula technology of the functional masterb...
