AI Technical Summary

Benefits of technology

This patented technology uses special substances called gas or silanes (SiH) instead of traditional plastic materials like PolyVinyl Chloride (PVCl). These new compounds have excellent physical characteristics such as good flame retardant property, low smoke emission during burning, strong impact strength, durability against weather conditions, long life under load, minimal residual charges on conductors, etc., making them ideal candidates for use in various applications where safety concerns exist.

Problems solved by technology

This patented technical solution describes different ways to make polymer compositions suitable for various applications like electrical conductors due to its ability to resist electrostatic charge buildup without causing damage during winding processes. These techniques involve adding special agents called anti-eletronics onto existing plastic materials while maintaining excellent performance characteristics over time. Additionally, these new methods involving specific chemical structures and processing technologies may be developed at home and abroad by companies involved in the relevant fields where AC/DC voltage levels exceed 1 million volts.

Embodiment 1

[0045] The silane cross-linked polyethylene insulating material for wire and cable is prepared from the following components by weight percentage:

[0046]

[0047] and catalyst masterbatch;

[0048] Described catalyst masterbatch is made of following component:

[0049]

[0050] The two-step method for preparing silane cross-linked polyethylene insulating materials for wires and cables mainly consists of two parts, one is the preparation of catalyst masterbatch, and the other is the preparation of finished products.

[0051] 1. Catalyst masterbatch preparation:

[0052] Stir the above materials in the mixer, first stir at low speed for 1 minute and then at high speed for 3 minutes, then release and pour into the hopper of the extruder (extruder temperature: 140-180°C), extrude through the twin-screw, and then pass through the cooling water tank for cooling , and then blown dry by a fan before cutting into pellets. The pellets are dried in a drying tower (set at 80°C) ...

Abstract

The invention relates to the field of insulating materials, in particular to a silane crosslinked polyethylene insulating material for wires and cables and a preparation method of the material. The silane crosslinked polyethylene insulating material for the wires and cables is prepared from LLDPE-7042, LDPE, a silane coupling agent, a cross-linking agent DCP, an antioxidant 300 and catalyst master batches; the catalyst master batches are prepared from LLDPE-7042, LLDPE-8320, PP, an antioxidant 1010, an antioxidant DLTP, an antioxidant 1024, organic tin and fluorine rubber master batches. The insulating material is mainly used for insulating layers of the cables to replace existing PVC materials, the insulating property of the insulating material is superior to that of PVC, PVC can give out poisonous and harmful gases when a fire breaks out due to wire aging and the like, and the silane insulating material is poisonless and harmless.
