Embodiment 1

[0040] Example 1: The components and their parts by weight are as follows.

[0041]

[0042] All of the above components are commercially available from the market.

[0043] Firstly mix EVA (with 14% VA content), LLDPE, AT-10, DSTP, PE-g-MAH, silicone, aluminum hydroxide, and calcium carbonate on the internal mixer, and granulate them as A and B materials The public masterbatch. The silane coupling agent, antioxidant, and initiator are formulated into silane additives, the master batch is used to absorb the silane additives, and the obtained material A is vacuum-packed in an aluminum-plastic composite bag; the master batch is used to absorb dibutyl tin dilaurate, and aluminum-plastic The compound bag is packaged with material B.

[0044] Combine material A and material B (material A: material B=95:5 (weight ratio)) to obtain a polyolefin insulating material.

Embodiment 2

[0045] Example 2: The components and their parts by weight are as follows.

[0046]

[0047] A polyolefin insulating material was prepared according to the same method as in Example 1, wherein material A: material B=96:4 (weight ratio).

Embodiment 3

[0048] Example 3: The components and their parts by weight are as follows.

[0049]

[0050]

[0051] A polyolefin insulating material was prepared according to the same method as in Example 1, wherein material A: material B=95:5 (weight ratio).

Abstract

The invention relates to an easy-peel highlighted silane crosslinking flame-retardant polyolefin insulation material, a preparation method and application thereof, and aims to provide the polyolefin insulation material relatively good in mechanical property and electrical property. A prepared insulating layer of a low-smoke halogen-free flame-retardant cable is uniform in crosslinking, excellent in temperature endurance and easy to peel after being made into the cable, and in a high-speed paying-off situation, the cable surface is free of melt fracture, smooth, highlighted and easy to peel. The technical scheme is as follows: the polyolefin insulation material comprises an A material and a B material, wherein the A material comprises the following components: EVA, PE, a silane coupling agent, a primary antioxidant, an auxiliary antioxidant, an initiator, a compatilizer, a lubricating agent, a fire retardant and a filler; the B material comprises the following components: EVA, PE, a catalyst, a primary antioxidant, an auxiliary antioxidant, a compatilizer, a lubricating agent, a fire retardant and a filler.

Description

Technical field [0001] This application relates to a polyolefin insulating material and its preparation method and application, and more particularly to a cable with low cost, good temperature resistance (resistance to 125°C), bright cable surface and easy peeling characteristics of cable insulation Silane cross-linked low-smoke halogen-free flame-retardant polyolefin insulating material and preparation method and application thereof belong to the technical field of wire and cable materials. Background technique [0002] With the rapid development of China's economy and the rapid development of various electronic products, home appliances, and lighting products, the market has explosive growth in demand for various processing lines such as stripped terminal wires. In particular, some high-end cables have special requirements such as high temperature resistance, low smoke, halogen free and flame retardant. The material requirements for this type of processing line are upgraded fr...
