Embodiment 1
[0026] A plastic hollow pipe network, raw materials include polypropylene, polyethylene, and auxiliary materials; auxiliary materials include linear materials, elastic bodies, tackifiers, tackifiers, anti-aging agents, and anti-ultraviolet agents.
[0027] Polypropylene and polyethylene account for 70-80wt% of the total formula, and other auxiliary materials account for 20-30wt%. The shape of the hollow network pipe is a rhombus network (such as figure 1 shown):
[0028] An extrusion die is used to manufacture the above-mentioned plastic hollow pipe network to produce a tubular strip-shaped plastic net. On the production line for extruding the diamond-shaped net, the extrusion die is designed with the following structure:
[0029] A C-shaped die for extrusion; comprising an inner film tool 5 and an outer film tool 4; the inner film tool 5 is fixed on the inner rotating body 7 of the die head, the outer film tool 4 is fixed on the outer rotating body 6 of the die head, and the...
Embodiment 2
[0042] A plastic hollow pipe network, raw materials include polypropylene, polyethylene, and auxiliary materials; auxiliary materials include linear materials, elastic bodies, tackifiers, tackifiers, anti-aging agents, and anti-ultraviolet agents.
[0043] Polypropylene and polyethylene account for 70-80wt% of the total formula, and other auxiliary materials account for 20-30wt%. The shape of the hollow network pipe is a square grid (such as figure 2 shown):
[0044] An extrusion mouth mold is used to manufacture the above-mentioned plastic hollow pipe network to produce tubular strip-molded plastic nets. On the production line for extrusion grids, the extrusion mouth mold is designed with the following structure:
[0045] A C-shaped die for extrusion; comprising an inner film tool 5 and an outer film tool 4; the inner film tool 5 is fixed on the inner rotating body 7 of the die head, the outer film tool 4 is fixed on the outer rotating body 6 of the die head, and the inner ...

Abstract
The invention belongs to the technical field of plastic molds, and discloses a plastic hollow pipe network and a manufacturing mold and a manufacturing method thereof. The plastic hollow pipe networkis prepared from polypropylene, polyethylene or modified raw materials of polypropylene and polyethylene and auxiliary materials, wherein the auxiliary materials comprise a linear material, an elastomer, a tackifier, an anti-aging agent and an anti-ultraviolet agent. The plastic hollow pipe network can replace a foaming net to be used for packaging products, and has the advantages of being low incost, green, environmentally friendly and recyclable. The plastic hollow pipe network can replace a ground mat product and has high rebound resilience; and the mold is used for producing, so that thestructure is simple, and the lighter plastic hollow pipe network can be produced without using a foaming agent.
Description
technical field [0001] The invention belongs to the technical field of plastic moulds, and in particular relates to a plastic hollow pipe network and its manufacturing mold and manufacturing method. Background technique [0002] The existing traditional products are solid plastic mesh products or physically and chemically foamed plastic mesh products, which are generally produced by plastic extrusion through dies and moulds. Existing solid products are generally heavy in weight, inconvenient to use in some fields, and costly and wasteful during recycling. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a plastic hollow pipe network and its manufacturing mold and manufacturing method. The plastic hollow pipe network of the present invention can replace the foamed net for packaging products, and has the advantages of low cost, environmental protection, and renewable Recycled features. It can replace ...
