Embodiment 2
[0065] This embodiment discloses a method for producing a reinforced pipe body 11 using the production device of the pipe body in Embodiment 1. Step 1: After mixing polyvinyl chloride resin and glass fiber modified polypropylene in a mixing device, add titanate Coupling agent, vinyltrimethoxysilane, calcium carbonate, n-octadecyl propionate, titanium dioxide, and benzophenone-type ultraviolet absorbers are mixed;
[0066] Step 2: After being extruded by an extruder, the product is obtained after successively sizing, cooling, pulling, cutting, and testing.
[0067] Preferably, 70~90 parts of polyvinyl chloride resin, 1~3 parts of titanate coupling agent, 1~2 parts of vinyltrimethoxysilane, 10~20 parts of glass fiber modified polypropylene, 20~20 parts of calcium carbonate 35 parts, 0.1 to 0.5 parts of n-octadecanyl propionate, 1 to 2 parts of titanium dioxide, 2 to 5 parts of benzophenone ultraviolet absorbers; the temperatures of the extruder from the hopper to the die are res...
Embodiment 3
[0069] Such as Figure 10-12 As shown, this embodiment discloses a composite pipe body 11, which sequentially includes raw material mixing, extrusion, cooling, pulling, and cutting. The tube body 11 includes an inner layer tube body 111 and an outer layer tube body 112, and a gap layer is formed between the inner layer tube body 111 and the outer layer tube body 112;
[0070] A skeleton 13 is arranged in the gap layer, and the two ends of the skeleton 13 are respectively connected with the inner layer pipe body 111 and the outer layer pipe body 112; Surrounding the center at intervals, an accommodating cavity 14 is formed between the adjacent skeleton 13 and the inner tube body 111 and the outer tube body 112 .
[0071] The pipe body 11 is prepared from the following raw materials in parts by mass: 70-90 parts of polyvinyl chloride resin, 1-3 parts of titanate coupling agent, 1-2 parts of vinyltrimethoxysilane, glass fiber modified 10-20 parts of polypropylene, 20-35 parts o...
