Abstract
The invention relates to a polyethylene jacket material, in particular to a polyethylene jacket material for a cable. The polyethylene jacket material for the cable consists of high-density polyethylene resin, medium-density polyethylene resin, linear low-density polyethylene resin and an antioxidant processing aid and is prepared by weighing, mixing, extruding, grain cutting, drying and packaging.
Description
Technical field
The present invention relates to a kind of polyethylene sheath material, relate in particular to a kind of Polethylene protecting sheath material for optical cable.
Background technology
At present, along with China's development of economic construction, communication career also makes rapid progress is taking place to change, the specification of quality that is used for the communication cable sheath material is more and more higher, people wish that it has good weathering resistance, toughness, outside wear resistance and the environmental stress crack resistance, people also wish simultaneously good technology capability and flexibility to be arranged, the optical cable smooth surface that grows is smooth, and the existing optical cable of producing mostly is the high density polyethylene(HDPE) sheath material with sheath, its processing temperature is than higher, and this has just proposed higher requirement to the equipment of producing optical cable, and difficulty of processing is bigger, and the optical cable hardness height of producing, relatively more difficult for the one-tenth dish of optical cable.In a word, the optical cable product that existing sheath material is produced is not ideal enough, so existing sheath material and preparation technology thereof await further improvement.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of polyethylene sheathing material for optical cable, it is made up of high-density polyethylene resin, medium-density polyethylene resin, ldpe resin, type low density polyethylene resin, antioxidant processing aid, through weighing, mix, extrude, pelletizing, drying, packing form, and it is characterized in that it is an optical cable sheath material by the raw material preparing of following weight (kg) proportioning:
High-density polyethylene resin 35-55 antioxidant 0.1-0.5
Medium-density polyethylene resin 5-15 processing aid 0.05--0.2
Type low density polyethylene resin 35-50 carbon black master batch 4.8-5.6.
Wherein, described polyethylene sheathing material, its feature also is: it is the sheath material of the raw material preparing of preferred following weight (kg) proportioning:
High-density polyethylene resin 42.5 antioxidants 0.2
Medium-density polyethylene resin 9 processing aids 0.1
Type low density polyethylene resin 43 carbon black master batches 5.2.
Embodiment
Below in conjunction with covering example further specifies the present invention in fact
Embodiment
1. be purchased the also starting material of weighing following weight (1c9) proportioning
High-density polyethylene resin 42.5 antioxidants 0.2
Medium-density polyethylene resin 9 processing aids 0.1
Type low density polyethylene resin 43 carbon black master batches 5.2.
2. above-mentioned starting material are mixed, standby @ extrudes standby mixing material with twin screw extruder, and its screw speed is 240-280 rev/min
3. pelletizing, its granular size is cut into the round shaped grain of towel 3mm,
4. use the drying machine drying, promptly get 100K9 polyethylene sheathing material for optical cable of the present invention.Have another name called and be optical cable
Use the medium-density polyethylene sheath material.
Polyethylene sheathing material for optical cable of the present invention carries out performance test through the sheath material to trial-production, and its every performance is the requirement of energy accord with Q/HFT001-1997 standard all.
On optical cable factory optical fiber cable RVV this sheath material has been carried out technological test, main condition are as follows:
1. processing temperature barrel zone temperature: 150-250 " C head temperature: 200-230 ℃ filter screen: so-120 order
2. the plasticizing of sheath material material is even, and it is better to extrude processing characteristics
3. the jacket surface of extruding is smooth, surround whole, no magazine and other defective, and the jacket surface quality according with process requirements,
4. the sheath spark test does not have breakdown point.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of claim of the present invention.
