Abstract
The invention provides a kind of improvement warm water crosslinking black insulated aerial cable material, change the most traditional method and i.e. base material A and B are expected to add high-carbon black pigment, carry out in proportion using attached suction method processing mode to become warm water crosslinking black aerial cable material after pelletize.The value that aerial cable and other black crosslinked polyethylene jacketed cable are widely used.
Description
Technical field
The present invention relates to electric wire and manufacture field, the warm water crosslinking black insulated aerial cable of a kind of improvement
Material.
Background technology
The existing traditional method of electric wire manufacturing manufactures black aerial cable, is respectively adopted two step method or one-step method
Add black masterbatch after silane crosslinked insulating material and carry out on-the-spot agitating use.
Two step method and one-step method silanes crosslinked Insulation Material also exist a fatal weakness jointly.
1, be respectively adopted A material B material mixing addition black color masterbatch, generation distributing precision is difficult to control to, special black masterbatch adds
Before to carry out drying otherwise water content and be difficult to produce preferable qualified products, easily give crosslinking.
2, specify according to cable product standard: black aerial cable material content of carbon black has certain requirement, use black masterbatch
Grain does not reaches requirement at all, can disperse inequality when black agglomerate is added, and content of carbon black is the most uneven, more have a strong impact on friendship
Connection degree gel calorimetric extends instability, causes product defective.
Summary of the invention
The present invention is to solve problem of the prior art, it is provided that a kind of improvement warm water crosslinking black insulated aerial cable
Material, content of carbon black is evenly distributed, and heat extends stable, and conforming product rate is high.
The present invention includes the component of following mass fraction:
Primary base material 20-80 part；
Primary B expects 10-50 part；
Silane 1-10 part；
Cross-linking agent 1-10 part；
Described primary base material includes the component of following mass fraction；
LDPE melting means (8-20) 10-80 part；
LDPE melting means (1.5-2.5) 20-30 part；
White carbon black height pigment 2-20 part；
Described primary B material includes the component of following mass fraction；
LLDPE 50-90 part；
LDPE 10-50 part；
Copper resistant agent 1-5 part；
Organotin 1-15 part；
Antioxidant 1-5 part；
Rheological agent 1-5 part；
White carbon black 2-20 part.
The present invention has the beneficial effects that: changes the most traditional method and i.e. base material A and B is expected to add high-carbon black pigment double
Screw pelletizer mixing granulation, carries out using attached suction method processing mode to become warm water crosslinking black insulated aerial cable the most in proportion
Material, content of carbon black is evenly distributed, and heat extends stable, and conforming product rate is high, protects aerial cable and other black crosslinked polyethylene
The value that set cable is widely used.
