Embodiment 1

[0032] The HDPE double-wall corrugated pipe is prepared through the following steps:

[0033] Step 1. In parts by weight, weigh 100 parts of HDPE resin, 40 parts of wood powder, 1 part of titanate coupling agent, 7 parts of EPDM rubber, and 30 parts of ultrafine glass fiber cotton;

[0034] Step 2. Dry the wood powder with two-stage combined pulse air flow, and dry it at 120°C for 1 hour to make its moisture lower than 300mg / kg. After cooling to normal temperature, mix it with titanate coupling agent, and heat it to 60°C. , stirred and dispersed at 1100 rpm for 5 minutes, then added EPDM rubber, stirred evenly and cooled automatically; then mixed the above-mentioned mixture with HDPE resin and ultra-fine glass fiber cotton, and sent it to the machine through a vacuum pipeline The platform is used to extrude the melt in the single-screw extruder on the outer wall of the double-wall corrugated pipe, and the melted embryo passes through the forming machine, cooling water tank, tr...

Abstract

The invention discloses a high-strength ultra-micro glass fiber cotton reinforced HDPE double-wall corrugated pipe. The HDPE double-wall corrugated pipe is prepared through the following steps that 1,100-120 parts by weight of HDPE resin, 40-60 parts by weight of wood flour, 1-3 parts by weight of a titanate coupling agent, 7-9 parts by weight of ethylene propylene diene monomer and 30-45 parts by weight of ultramicro glass fiber cotton are weighed; and 2, the wood flour is dried through two-stage combined pulse airflow. One side of the corrugated pipe makes contact with a second L-shaped rod, one end of the pipe is inserted into the clamping mechanism; meanwhile, three cylinders II are driven; a piston rod pushes a lifting block to ascend upwards in a sliding groove. A rubber base is pushed to move through a second rotating block, a connecting rod and a first rotating block, under cooperation of a rocker, the corrugated pipe is clamped through a rubber belt, the connecting rod is sleeved with a spring, through the arrangement of the spring, in the moving process of the rubber base, good buffering performance is achieved, and the corrugated pipe is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength ultramicro glass fiber cotton reinforced HDPE double-wall corrugated pipe. Background technique [0002] HDPE is one of the five most commonly used plastics in the world. Due to its good toughness and processability, it is widely used, and it is also widely used in municipal water supply and drainage pipes. Conventional HDPE double-wall corrugated pipes generally use talcum powder and calcium carbonate as reinforcement materials. Compared with glass fiber, there are disadvantages such as low strength, large weight, and obvious size shrinkage, which lead to problems such as low pipe ring stiffness, poor external pressure resistance, and high cost; Equipment, resulting in low efficiency of corrugated pipe forming, inconvenient for forming corrugated pipes with different diameters, poor practicability, and easy to bend during the forming process.
