The thread of sheathing the main raw material is plastic steel scrap, in the production process, molten materials twin-screw extruder, Direct though stereotypes, do not use single-screw extruder melting process, so that the production process is simple. This invention is the dominant effect: resolving the waste plastic steel products of recycling, to environmental protection, but also to reduce the existing thread buried cable sheathing of the cost of production, greatly improving the products flame retardant, aging resistance , rigid flexible, and to increase the economic benefits of this enterprise.
Description
Technical field
The present invention relates to a kind of cable recoil inserts pipe, specifically, relate to a kind of fire-retardant buried cable carbon-screw protective tube that utilizes waste plastic-steel to produce.
Background technology
Fire-retardant underground cable protecting pipe has been widely used on the power cable industry at present, and its production technology is also ripe.But, present protecting pipe production raw material, it is general that what adopt is that the pellets such as polyvinyl chloride, chliorinated polyvinyl chloride, polyethylene, polypropylene of finished product are primary raw material.Such as in patent documentation: name is called " power cable plastic protecting casing " (publication number CN1139278A), and the primary raw material that disclosed technical scheme is used is exactly polyvinyl chloride, chliorinated polyvinyl chloride; Name is called " a kind of buried mesohigh power cable sleeve pipe and production method thereof " (publication number CN1508925A), and the primary raw material that disclosed technical scheme is used is a polypropylene.Produce these raw materials that described protecting pipe uses, the price comparison height, institute is so that the also corresponding height of the protecting pipe price of utilizing these raw materials to make.
At present, produce the enterprise of plastic-steel goods, after finished product is made, have a large amount of waste plastic-steel (tailing) to produce, the processing of waste plastic-steel is the problem that enterprise has a headache very much; Also have the waste and old plastic-steel goods after people use, also be difficult to handle.Handle these waste and old plastic-steels and not only will spend great amount of manpower, and waste and old plastic-steel both causes environmental pollution, influence ecological environment as garbage disposal, also cause the significant wastage of limited resources, and the solution of these problems yet there are no relevant report so far.
Summary of the invention
Purpose of the present invention is to provide a kind of buried cable carbon-screw protective tube that utilizes waste plastic-steel to produce.This invention is turned waste into wealth, and utilizes waste and old plastic-steel resource to reduce the production cost of existing underground cable protecting pipe, can effectively reduce pollution, the protection environment of waste and old plastic-steel to environment on the other hand on the one hand.
For achieving the above object, the applicant provides following technical scheme:
A kind of buried cable carbon-screw protective tube that utilizes waste plastic-steel to produce, the raw material of this protecting pipe is formed (% meter by weight) by following component:
Waste plastic-steel powder 82～86%, haloflex 4.0～6.0%, composite lead heat stabilizer 1.35～1.65%, paraffin 0.27～0.33%, stearic acid 0.18～0.22%, carbon black 3～5%, auxiliary material 3.35～6.5%.
Described each proportion of raw materials is: waste plastic-steel powder 84%, haloflex 5.0%, composite lead heat stabilizer 1.5%, paraffin 0.3%, stearic acid 0.2%, carbon black 4%, auxiliary material 5.0%.
Described composite lead heat stabilizer adopts FJ-300, FJ-302 etc. (this product wins plastics Co., Ltd by the sky, Zhejiang and makes).
Described auxiliary material is at least a among Tissuemat E, dioctyl ester, soft PVC, the ACR (acrylic resin).
The manufacture method of above-mentioned buried cable carbon-screw protective tube is as follows:
1) earlier waste plastic-steel is selected materials, reject impurity wherein, the waste plastic-steel after the removal of impurity is ground into≤particle of 10mm, this particle is carried out abrasive dust handle, make waste plastic-steel powder (30～70 order);
2) by above-mentioned said raw material components batching;
3) all batchings are dropped into mixing in batch mixing canisters, drop into then mediate in the kneader to temperature be 90～110 ℃; Material after mediating is put twin-screw melt extrude, the twin-screw rotating speed is controlled at 30～50 rev/mins in this process, and barrel temperature is controlled at 149～180 ℃; The direct per os mould typing of material after melt extruding, wherein die temperature is controlled at 160～180 ℃, and typing penetrates wire final vacuum sizing, and again through cooling, the circle finished product is received in the traction cutting at last
The manufacture method of this cable carbon recoil inserts pipe and the manufacture method main difference of existing cable sheath tube be: after the material twin-screw melt extruded, directly per os mould typing no longer adopted single screw rod to melt extrude treatment process, makes manufacture method simple.
The invention has the beneficial effects as follows:
Because this protecting pipe; adopted waste plastic-steel as primary raw material (PVC regeneration); efficiently solving the plastic-steel tailing of plastic-steel production of articles producer and the waste and old plastic-steel goods after people's use handles problems; reduced of the pollution of waste and old plastic-steel to environment; reach the environmental protection purpose, improved resource utilization simultaneously.
The buried cable carbon-screw protective tube that adopts the technical program to produce is compared with the existing raw material of producing fire-retardant underground cable protecting pipe use, raw material per ton thousands of units that can reduce cost, greatly reduce the producer price of underground cable recoil inserts pipe like this, improved the economic benefit of relevant enterprise greatly.
The product that the buried cable carbon-screw protective tube product quality that adopts the technical program to produce is produced with prior art is compared, and proves through application test, has improved the anti-flammability, ageing resistance, hard and soft property of product etc. greatly.
The production of this protecting pipe has made full use of its main raw material(s)---the intensity of waste plastic-steel, hardness, toughness, fire-retardant, radioresistance, anti-aging characteristic, so this product can be widely used in can also being applied to industries such as building, chemical industry, mine, water conservancy, plumbing outside electric power, the communications industry.
Buried cable carbon-screw protective tube of the present invention (the fire-retardant buried cable carbon-screw protective tube of name of product: SY-PVC, also claim the fire-retardant underground cable recoil inserts of SY-PVC pipe), by " " Chengdu Xing Sanyi building materials Co., Ltd " sample presentation check; through " Deyang City product quality supervision and testing institute " check; its check conclusion: according to the GB/T13381.1-1992GB/T10002.3-1996 standard test, index that this sample is examined qualified (seeing Table).
