Problems solved by technology

Because the steel belt reinforced polyethylene spiral corrugated pipe has the characteristics of high rigidity, high strength, corrosion resistance, wear resistance and strong flexibility, it is widely used in the drainage field as a cost-effective steel-plastic pipe. However, In the production process, the yield strength of the steel strip material varies greatly, therefore, the same bending degree cannot guarantee that the steel strip reaches the yield limit, so that there is a certain rebound stress in the steel strip, which makes the forming of the pipe difficult and easy to break. The bonding is not strong, it is easy to cause delamination problems, and there are certain safety hazards during installation and use

Abstract

The invention discloses a high-rigidity steel belt reinforced polyethylene spiral corrugated pipe and a preparation method thereof. The high-rigidity steel belt reinforced polyethylene spiral corrugated pipe comprises an inner polyethylene pipe, formed steel belts and an outer polyethylene pipe. The formed steel belts are wound around the outer surface of the inner polyethylene pipe at equal intervals and wrapped by the outer polyethylene pipe. The inner polyethylene pipe and the outer polyethylene pipe respectively comprise, by weight, 80-86 parts of high density polyethylene, 8-10 parts of magnesium hydrate, 4-6 parts of compatilizers, 3-4 parts of dibutyltin dilaurate, 2-4 parts of calcium hypophosphite, 2-3 parts of polyoxyethylene, 5-6 parts of polyethylene-graft-maleic anhydride, 7-9 parts of alkyl phosphoric acid, 3-6 parts of superfine talcum powder, 5-7 parts of lustering agents for plastic, 6-8 parts of aluminium-zirconium coupling agents, 4-5 parts of vinyltriethoxysilane, 4-7 parts of beta (3,5 di-tert-butyl-4-hydroxycyclohexyl phenyl ketone) propionic acid octadecyl ester, 5-8 parts of color master batches and 10-12 parts of assistant master batches. According to the high-rigidity steel belt reinforced polyethylene spiral corrugated pipe and the preparation method of the high-rigidity steel belt reinforced polyethylene spiral corrugated pipe, the technology is simple, the production cost is low, pipes are not likely to be fractured, adhesive bonding is firm, the layering problem is not likely to be produced, and using is safe and reliable.

Description

technical field [0001] The invention relates to a polyethylene spiral corrugated pipe, in particular to a high-rigidity steel strip reinforced polyethylene spiral corrugated pipe and a preparation method thereof. Background technique [0002] The steel belt reinforced polyethylene spiral corrugated pipe is based on high-density polyethylene, and the steel belt coated with adhesive resin is formed into a corrugated main support structure, and is wound and compounded with polyethylene material to form an integral double-walled spiral corrugated pipe. Because the steel belt reinforced polyethylene spiral corrugated pipe has the characteristics of high rigidity, high strength, corrosion resistance, wear resistance and strong flexibility, it is widely used in the drainage field as a cost-effective steel-plastic pipe. However, In the production process, the yield strength of the steel strip material varies greatly, therefore, the same bending degree cannot guarantee that the stee...
