Embodiment 1

[0008] According to the weight percentage of the above raw materials: PVC resin 60%, calcium carbonate 24%, chlorinated polyethylene 5.4%, stabilizer 3.9%, ACR resin 2.7%, paraffin wax 0.6%, polyethylene wax 1.8%, stearic acid 1.6%, Put it into the mixer, mix it at 110°C, and cool it automatically after reaching the requirements. After passing through the vibrating screen, it will automatically feed the material, extrude it through high temperature and high pressure by the twin-screw extruder, and pull the product out through the molding machine. Machine fixed-length cutting, sent to the flaring machine, after the flaring is completed, it is packaged and put into storage.

Embodiment 2

[0010] According to the weight percentage of the above raw materials: PVC resin 64%, calcium carbonate 18%, chlorinated polyethylene 5.6%, stabilizer 4.2%, ACR resin 3%, paraffin wax 1.2%, polyethylene wax 1.8%, stearic acid 2.2%, Put it into the mixer, mix it at 130°C, and cool it automatically after reaching the requirements. After passing through the vibrating screen, it will automatically feed the material, extrude it through high temperature and high pressure by the twin-screw extruder, and pull the product out through the molding machine. Machine fixed-length cutting, sent to the flaring machine, after the flaring is completed, it is packaged and put into storage.

Embodiment 3

[0012] The above-mentioned raw materials are by weight percentage: PVC resin 62%, calcium carbonate 20%, chlorinated polyethylene 6%, stabilizer 4%, ACR resin 3%, paraffin 1%, polyethylene wax 2%, stearic acid 2%, Put it into the mixer, mix it at 140°C, and cool it automatically after reaching the requirements. After passing through the vibrating screen, the material is automatically loaded, extruded by the twin-screw extruder through high temperature and high pressure, and the product is pulled out by the molding machine. Machine fixed-length cutting, sent to the flaring machine, after the flaring is completed, it is packaged and put into storage.

Abstract

The invention discloses a formula of a PVC (Poly Vinyl Chloride) double-wall corrugated pipe, and a production technology of the PVC (Poly Vinyl Chloride) double-wall corrugated pipe. The formula comprises the components as follows: PVC resin, calcium carbonate, chlorinated polyethylene, stabilizing agent, ACR resin, paraffin, polyethylene wax and stearic acid, wherein the components are in percentage by weights as follows: 60 to 72% of PVC resin, 18 to 30% of calcium carbonate, 5.4 to 7.2% of chlorinated polyethylene, 3.9 to 4.8% of stabilizing agent, 2.7 to 3% of ACR resin, 0.6 to 1.2% of paraffin, 1.2 to 2.4% of polyethylene wax, and 1.5 to 2.4% of stearic acid. The formula has the advantages that the PVC double-wall corrugated pipe is formed by extruding PVC resin which is served as the main raw material at high temperature and high pressure; the PVC double-wall corrugated pipe has resistance to impacting, resistance to high temperature and coldness, and has long service life, and is applied to paving underground communication pipelines, as well as performing protection to communication optical cables and cables.

Description
