Abstract
A kind of polyethylene foamed composite pipe, belongs to pipe structure technical field.It is the outer three-layer co-extruded extruding and moulding of the high density polyethylene (HDPE) PE100 internal layer of 2:7:1, high density polyethylene (HDPE) PE100 microporous foam mesosphere and organosilane crosslinked polyethylene by wall ratio.The utility model is by adopting above-mentioned technology, the foam material density in high density polyethylene (HDPE) PE100 microporous foam mesosphere is only the 68%-74% of original resin, materials are saved, economic benefit is obvious, and pipeline overall weight alleviates about 20%, reduce cost of transportation, convenient construction is carried, be used in drainage system and can reduce current noise, its skin thickness and expansion ratio easily control, the outward appearance of goods and inherent quality are all better, impact resistance improves, as communication cable cage walls, optical cable pipe box, can available protecting interior cables, also can be used for low-pressure industrial and low pressure domestic water line etc.
Description
Technical field
The utility model belongs to pipe structure technical field, is specifically related to one and has both had certain resistance to cracking and withstand voltage properties, has again the polyethylene foamed composite pipe of economic and practical simultaneously.
Background technique
Plastic tube, because having the advantages such as current loss little, energy-conservation, material-saving, protecting ecology, construction be convenient, is widely used in the fields such as building water supply and drainage, cities and towns plumbing and fuel tube, becoming the main force of new century urban construction pipe network.Because plastic tube rigidity is poor, general bigbore wall thickness is all comparatively large, and cost of raw material accounting is higher.The constantly progress of poly foaming technique, all can obtain the higher polyethylene foam-material of specific strength by chemical blowing or physical blowing, reduce raw-material use amount.A lot of pipeline producer also attempts applying in the duct, but the more difficult control of polyvinyl piping materials surface skining layer thickness after foaming, cause tubing resistance to cracking sharply to decline, there is serious potential safety hazard.In polyethylene foamed tube extrusion process, internal surface is owing to can not get cooling skinning timely, and foaming causes internal surface comparatively coarse, reduces pipeline transmission capacity.
Model utility content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide one both to have certain resistance to cracking and withstand voltage properties, have again the polyethylene foamed composite pipe of economic and practical simultaneously, may be used for low pressure feed water pipeline, polyethylene foamed composite pipe that communication cable covers pipe, optical cable pipe box etc.
Described a kind of polyethylene foamed composite pipe, for three-layer composite structure, it is characterized in that by high density polyethylene (HDPE) PE100 internal layer, high density polyethylene (HDPE) PE100 microporous foam mesosphere and organosilane crosslinked polyethylene outer three-layer co-extruded shaping, described high density polyethylene (HDPE) PE100 internal layer has smooth inner surface of pipeline; High density polyethylene (HDPE) PE100 microporous foam mesosphere cell size is even, effectively ensure that tubing intensity and connection reliability; The density of material in mesosphere is 0.65-0.70g/cm
3, the cell size in mesosphere is 20-40 μm.
Described a kind of polyethylene foamed composite pipe, is characterized in that described high density polyethylene (HDPE) PE100 internal layer, high density polyethylene (HDPE) PE100 microporous foam mesosphere and organosilane crosslinked polyethylene outer wall thickness rate are 2:7:1.
Above-mentioned a kind of polyethylene foamed composite pipe, for three-layer composite structure, it is by the outer three-layer co-extruded extruding and moulding of high density polyethylene (HDPE) PE100 internal layer, high density polyethylene (HDPE) PE100 microporous foam mesosphere and organosilane crosslinked polyethylene, and described high density polyethylene (HDPE) PE100 internal layer has smooth inner surface of pipeline; High density polyethylene (HDPE) PE100 microporous foam mesosphere cell size is even, effectively ensure that tubing intensity and connection reliability; The density of material in mesosphere is 0.65-0.70g/cm
3, the cell size in mesosphere is 20-40 μm.The utility model is by adopting above-mentioned technology, the foam material density in high density polyethylene (HDPE) PE100 microporous foam mesosphere is only the 68%-74% material saving of original resin, economic benefit is obvious, and pipeline overall weight alleviates about 20%, reduce cost of transportation, convenient construction is carried, be used in drainage system and can reduce current noise, its skin thickness and expansion ratio easily control, the outward appearance of goods and inherent quality are all better, impact resistance improves, as communication cable cage walls, optical cable pipe box can available protecting interior cables, also can be used for the field such as low-pressure industrial and low pressure domestic water line.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-high density polyethylene (HDPE) PE100 internal layer, 2-high density polyethylene (HDPE) PE100 microporous foam mesosphere, 3-organosilane crosslinked polyethylene is outer.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As shown in Figure 1, polyethylene foamed composite pipe of the present utility model, for three-layer composite structure, it is by the outer 3 three-layer co-extruded extruding and moulding of high density polyethylene (HDPE) PE100 internal layer 1, high density polyethylene (HDPE) PE100 microporous foam mesosphere 2 and organosilane crosslinked polyethylene, the material that high density polyethylene (HDPE) PE100 internal layer 1 uses is special material for pipeline high density polyethylene (HDPE) PE100, provides smooth inner surface of pipeline; High density polyethylene (HDPE) PE100 microporous foam mesosphere 2, by controlling mesosphere cell size and uniformity, effectively ensure that tubing intensity and connection reliability; The density of material that this layer uses is 0.65-0.70g/cm3, and the cell size in mesosphere is 20-40 μm; Organosilane crosslinked polyethylene outer 3 is organosilane crosslinked polyethylene layer PE-Xb, provides excellent anti-scratch performance.
The preparation method of polyethylene foamed composite pipe of the present utility model is:
This tubing is by coextrusion mold, and three extruders put into respectively by the material of three layers, got to know by a co-extrusion, respectively shaping high density polyethylene (HDPE) PE100 internal layer 1, high density polyethylene (HDPE) PE100 microporous foam mesosphere 2 and organosilane crosslinked polyethylene skin 3; High density polyethylene (HDPE) PE100 microporous foam mesosphere 2 adopts chemical blowing, stabilizer and resin, auxiliary agent etc. stir all, directly extruded by extruder and co-extrusion die head, outer 3 wall ratios of high density polyethylene (HDPE) PE100 internal layer 1 of the present utility model, high density polyethylene (HDPE) PE100 microporous foam mesosphere 2 and organosilane crosslinked polyethylene are 2:7:1.
