Problems solved by technology

[0002] At present, the main problem of domestic HDPE double-wall corrugated pipes is that it is difficult to produce high-ring stiffness pipes. Many manufacturers use high-strength filler masterbatch to enhance the ring stiffness of the pipes, but the amount of high-strength filler masterbatch cannot be increased, otherwise It will lead to the brittleness of the pipe, so only the size and weight of the pipe will be increased, which will increase the production cost virtually, and will fall behind in the competition with the coiled pipe and carat pipe

Embodiment 1

[0016] First weigh 125KG of HDPE recycled material, 7KG of defoamer, and 7KG of black masterbatch into the mixer, mix for 5 minutes, then add 200KG of HDPE polyethylene grade 80 new material, 150KG of PP polypropylene raw material, mix for 5 minutes, and finally Weigh 6KG of plasticizer, 4KG of coupling agent, and 1KG of dispersant. After mixing for 20 minutes, transport them to the granulator for granulation to obtain a stable HDPE formula mixture; the prepared HDPE formula mixture Add to the mixer, weigh 270KG high-strength filler masterbatch for HDPE, 16KG black masterbatch, mix for 5 minutes, then add lubricant 14KG, defoamer 24KG, elastomer material 60KG, stabilizer 16KG, mix and stir for half an hour , sucked into the outer wall of the corrugated pipe, plasticized and extruded to produce HDPE corrugated pipes with a new production formula. In the production process, process adjustments can be made according to the actual situation of the extruded material in order to ach...

Embodiment 2

[0021] First, weigh 100KG of HDPE recycled material, 6.4KG of defoamer, and 4.8KG of black masterbatch, add them to the mixer, mix for 5 minutes, then add 160KG of HDPE polyethylene 80 grade new material, 120KG of PP polypropylene raw material, and mix for 5 minutes. Minutes, finally weigh 4.8KG of plasticizer, 3.2KG of coupling agent, and 0.8KG of dispersant. After mixing for 18 minutes, transport them to the granulator for granulation to obtain a stable HDPE formula mixture; Put the good HDPE formula mixture into the mixer, weigh 210KG high-strength filler masterbatch for HDPE, 14KG black masterbatch, mix for 5 minutes, then add lubricant 12KG, defoamer 16KG, elastomer material 40KG, stabilizer 8KG , After mixing and stirring for 25 minutes, it is sucked into the outer wall of the bellows to be plasticized and extruded to produce HDPE bellows with a new production formula. In the production process, process adjustments can be made according to the actual situation of the ext...

Embodiment 3

[0023] First, weigh 75KG of HDPE regenerated material, 4.8KG of defoamer, and 3.6KG of black masterbatch, add them to the mixer, mix for 4 minutes, then add 120KG of HDPE polyethylene grade 80 new material, 90KG of PP polypropylene raw material, and mix for 4 minutes. Minutes, finally weighed 3.6KG of plasticizer, 2.4KG of coupling agent, 0.6KG of dispersant, after mixing for 15 minutes, transported to the granulator for granulation to obtain a stable HDPE formula mixture; Put the good HDPE formula mixture into the mixer, weigh 150KG high-strength filler masterbatch for HDPE, 8KG black masterbatch, mix for 4 minutes, then add lubricant 6KG, defoamer 10KG, elastomer material 22KG, stabilizer 4KG, after mixing and stirring for 20 minutes, it is sucked into the outer wall of the bellows to be plasticized and extruded to produce HDPE bellows with a new production formula. In the production process, process adjustments can be made according to the actual situation of the extruded m...

Abstract

Mixed materials of HDPE bellows and a manufacturing method thereof are disclosed. The raw materials contain the following ingredients (by weight): 50-60% of HDPE formula mixture, 25-30% of HDPE high-strength filling master-batch, 1-3% of an antifoaming agent, 1-2% of black master-batch, 4-7% of an elastomer material, 0.5-2% of a lubricant, and 0.5-2% of a sterilizing agent. The HDPE formula mixture comprises the following ingredients (by weight): 30-40% of HDPE polyethylene 80-class or 100-class fresh material, 10-25% of HDPE reclaimed material, 20-30% of PP polypropylene material, 1-2% of black master-batch, 0.5-2% of a coupling agent, 1-3% of an antifoaming agent, 1-3% of a plasticizer and 0.1-0.2% of a dispersant. The HDPE bellows produced by the use of the mixed raw materials has high strength, high toughness, good shock strength and high ring stiffness. The manufacturing method comprises steps of weighing materials, mixing and manufacturing pipes. The technology is simple and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of HDPE pipes, in particular to a mixed raw material and a manufacturing method of HDPE corrugated pipes. Background technique [0002] At present, the main problem of domestic HDPE double-wall corrugated pipes is that it is difficult to produce high-ring stiffness pipes. Many manufacturers use high-strength filler masterbatch to enhance the ring stiffness of the pipes, but the amount of high-strength filler masterbatch cannot be increased, otherwise It will cause the pipe to be brittle, so the only way to increase the size and weight of the pipe is to increase the production cost virtually, and it will fall behind in the competition with the coiled pipe and the carat pipe.
