Embodiment 1

[0049] (1) Mixing of high frosted full matte halogen-free flame retardant TPE system

[0050] Add SEBS and white oil into the mixer, and complete the oil-filling of SEBS under low-speed stirring; mix the oil-extended SEBS and other components evenly under high-speed stirring;

[0051] (2) Extrusion granulation

[0052] Completing the mixing, plasticizing and extruding granulation of the composition in a co-rotating twin-screw extruder;

[0053] (3) Material performance test

[0054] The dried material is injected into the injection molding machine to produce standard samples specified in various test standards, and the relevant material properties are tested. Qualified cables are prepared on the wire and cable pulling equipment, samples are taken and relevant wire and cable tests are carried out.

[0055] Among the main concerns are the tensile properties, gloss, roughness of the material and the flame retardancy of the cable. The materials and proportions in the examples ...

Embodiment 2

[0057] The implementation process is the same as in Example 1, the only difference being the adjustment of the ratio of TPE base material and TPEE. Other materials and proportioning are shown in Table 2, and the obtained material results are shown in Table 2.

Embodiment 3

[0059] The implementation process is the same as in Example 1, the difference is only in adjusting the ratio of TPE base material and PET resin. Other materials and proportioning are shown in Table 2, and the obtained material results are shown in Table 2.

Abstract

The invention discloses a high-frosted all-matte flexible halogen-free flame-retardant thermoplastic elastomer dedicated material for wires and cables, comprising a TPE (thermoplastic elastomer) base material system, a halogen-free flame-retardant system and other aids, and also comprising an appearance adjusting system; the appearance adjusting system comprises TPEE (thermoplastic polyether ester elastomer), PET (polyethylene terephthalate) resin, high-molecular-weight SEBS (styrene-ethylene / butylene-styrene block copolymer) and a high-molecular-weight compatibilizer; the molecular weight of the high-molecular-weight SEBS is 350000 to 450000. In order to solve the problem that both delustering and frosting in the prior art cause performance deterioration in material, the invention provides the high-frosted all-matte flexible halogen-free flame-retardant thermoplastic elastomer dedicated material for wires and cables; the appearance adjusting system is composed of the TPEE, PET resin, high-molecular-weight SEBS and high-molecular-weight compatibilizer, the appearance adjusting system is combined with a base system, and wires and cables prepared have high-delustered appearance and fine frost effect, with properties of the material maintained.

Description

technical field [0001] The invention relates to the technical field of wire and cable materials, in particular to a high-frosted full-matte flexible halogen-free flame-retardant thermoplastic elastomer special material for wires and cables and a preparation method thereof. Background technique [0002] The halogen-free flame-retardant thermoplastic elastomer (TPE) cable material is basically composed of a SEBS-based TPE conventional system 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 It completely avoids the ...
