Abstract

The invention relates to a steel band reinforced antibacterial PE (polyethylene) water supply pipe and a preparation method thereof. The steel band reinforced antibacterial PE water supply pipe sequentially comprises an antibacterial layer, an inner PE layer, a steel band layer and an outer PE layer from interior to exterior. The preparation method comprises the following steps of precoating the steel band layer with the inner PE layer; respectively extruding the antibacterial layer and the outer PE layer to the inner side and the outer side of the steel band layer precoated with the inner PE layer. The steel band reinforced antibacterial PE water supply pipe has the characteristics that the strength is high, the corrosion-resistant property is realized, the service life is long, the environment-friendly and sanitation effects are realized, the pollution is avoided, the connection property is firm and reliable, the sealing property is strong, the water leakage is avoided, the blasting is avoided, and the like; the preparation method of the steel band reinforced antibacterial PE water supply pipe has the advantages that the steel band reinforced antibacterial PE water supply pipe with the characteristics can be prepared; the antibacterial layer, the inner PE layer and the outer PE layer are co-extruded to the steel band layer, and all the layers can be melted to form a firm non-disengaging whole structure, so that the use of hot melt glue is avoided.

Description

Technical field [0001] The invention relates to the technical field of pipelines, in particular to a steel belt reinforced antibacterial PE water supply pipe and a preparation method thereof. Background technique [0002] At present, the water supply pipes on the market mainly include galvanized steel pipes, PP-R pipes, PE pipes and PE-RT pipes, etc., which have low corrosion resistance. After long-term use, it is easy to form scale, attach or breed microorganisms, and cause water quality to decline. Affect the health of the people; and the shortcomings of low impact resistance and compressive strength, frequent occurrence of explosion accidents, and increase in pipeline network leakage rate year by year. Summary of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a steel belt reinforced antibacterial PE water supply pipe with high strength, corrosion resistance, anti...
