Abstract

The invention discloses a novel modification formula of a steel belt pipe. The specific production method comprises the following steps that S1, a production technology principal compiles a special scheme for the production of the novel steel belt pipe, compiles a targeted emergency plan, and carries out the technical disclosure work on the production principal and a worker before production; S2, the steel belt, HDPE polyethylene resin, a PP toughening agent, adhesive resin, an HDPE linear material, glass fibers, a defoaming agent, an antioxidant and a coupling agent are weighed in corresponding parts by weight for later use; S3, the steel belt weighed in the second step is put into an ultrasonic cleaning machine in a segmented mode, clear water and a sodium carbonate solution are added for ultrasonic cleaning, the steel belt is quickly blow-dried in warm air, and dirt and impurities on the surfaces of particles are removed. The produced steel belt pipe is good in quality and performance, the wave crest of the steel belt corrugated pipe can be reduced, the external force impact resistance of the steel belt corrugated pipe is enhanced, and materials can flow smoothly.

Description

technical field [0001] The invention belongs to the technical field of steel strip pipe production, and in particular relates to a novel modified formula for steel strip pipes. Background technique [0002] 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 drainage and other fields as a cost-effective steel-plastic composite pipe. The structure of the steel belt reinforced polyethylene spiral corrugated pipe is: the inner layer is a continuous solid wall polyethylene inner pipe, the inner pipe is wound and compounded with a V-shaped steel belt pressed by a coated steel belt, and the inner pipe layer and The V-shaped steel belt is compounded with a polyethylene outer layer. The steel belt reinforced polyethylene spiral corrugated pipe is made into a solid steel belt reinforced polyethylene spiral corrugated pipe throu...
