Embodiment 1

[0047] (1) Oil-extending and plasticizing of SBS

[0048] Add SBS, softener vinyl polysiloxane (XHG-206-60000) and cross-linking system into the internal mixer, set the temperature of the internal mixer to 200°C, and the internal mixing time should not be less than 3 hours to complete the plasticization of SBS and mixing with softeners;

[0049] The crosslinking system is composed of di-tert-butyl peroxide and triallyl isocyanurate in a mass ratio of 1:1.

[0050] (2) Mixing of high-matte halogen-free flame-retardant TPE system

[0051] Add TPE matrix material system, phosphorus nitrogen flame retardant system and other additives, and mix the materials evenly under high-speed stirring;

[0052] The TPE matrix material system is obtained by mixing SEBS (Kraton G1651), 68# white oil and polypropylene (T30S) in a weight percentage of 50:30:20;

[0053] The phosphorus-nitrogen flame retardant system is obtained by mixing aluminum diethyl hypophosphite, polyphenylene oxide (PPO)...

Embodiment 2

[0061] The implementation process is the same as in Example 1, except that the ratio of SBS and vinyl polysiloxane is adjusted, and the ratio of SBS is increased. See Table 1 for other materials and their proportions, and see Table 1 for the performance test results of the obtained materials.

Embodiment 3

[0063] The implementation process is the same as in Example 1, except that the ratio of SBS and vinyl polysiloxane is adjusted, and the ratio of vinyl polysiloxane is increased. See Table 1 for other materials and their proportions, and see Table 1 for the performance test results of the obtained materials.

Abstract

The invention discloses a high-fogging halogen-free flame-retardant thermoplastic elastomer for electric wires and cables. The high-fogging halogen-free flame-retardant thermoplastic elastomer comprises the following raw materials in percentage by weight: 30-60wt% of a TPE base material system, 25-55wt% of a phosphorus-nitrogen composite flame-retardant system, 10-20wt% of SBS, 3-10wt% of vinyl polysiloxane and 1-5wt% OF A crosslinking system. In order to solve the problem of poor fogging effects of halogen-free flame-retardant TPE cable materials, the invention provides a halogen-free flame-retardant TPE cable material and a preparation method thereof, the appearance of the prepared cable has high fog surface effects, and other properties of the cable material can be maintained.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-matte halogen-free flame-retardant thermoplastic elastomer for wires and cables and a preparation method thereof. Background technique [0002] The halogen-free flame-retardant thermoplastic elastomer cable material is basically composed of a TPE (thermoplastic elastomer) conventional system based on SEBS (hydrogenated styrene-butadiene block copolymer) and a phosphorus-nitrogen-based halogen-free flame-retardant system. It is a kind of polymer alloy material with general-purpose plastic processing properties, but the product has properties similar to cross-linked rubber. The double bond in the molecular structure of SEBS is saturated, so it has anti-aging characteristics; the composition does not contain halogen, it is safe and non-toxic, good stability, soft texture, beautiful appearance, comfortable hand feeling, good resilience and strong moisture resistance ...
