Problems solved by technology

Due to the high technical content of manufacturing high-end products, the industry has high entry barriers, and the comprehensive performance meets the requirements of different grades of cables. In particular, there is a lack of TPE-S that can be industrially produced with a service temperature of 90°C / 105°C and above. (thermoplastic elastomer) high temperature resistant halogen-free flame retardant material

Embodiment 1 5

[0032] Embodiment operation process: the preparation method of thermoplastic elastomer composition for electric cable, has the following steps:

[0033] 1) Accurately weigh each component according to the mass percentage set by the formula;

[0034] 2) Divide the components of the above 1) into three parts according to the category of resin, flame retardant and small materials, small materials include char-forming agents, compatibilizers, flame-retardant synergists, antioxidants, processing aids, and Add weightless electronic scales respectively;

[0035] 3) Through the weight loss electronic weighing system, it enters the screw cylinder of the BUSS machine uniformly from the feeding port according to the preset ratio; through the unique reciprocating single-screw mixing process of the BUSS machine, the granulation process is completed by underwater granulation and the finished product is obtained.

[0036] The following table is the relevant performance parameters of the raw...

Abstract

The invention relates to insulated plastic, in particular to a cable thermoplastic elastomer composition and a preparation method thereof. The cable thermoplastic elastomer composition comprises the following components: 30 to 65 weight percent of styrene-ethylene-butadiene-styrene (SEBS), 5 to 20 weight percent of polypropylene, 5 to 15 weight percent of polyolefin elastomer (POE), 13 to 40 weight percent of fire retardant, 2 to 10 weight percent of charring gent, 0.5 to 5 weight percent of fire retarding assistant, 0.1 to 6 weight percent of compatilizer, 0.1 to 2 weight percent of antioxygen and 0.01 to 2 weight percent of processing assistant. The invention provides a formula technique and a production method of a halogen-free TPE-S thermoplastic elastomer composition with proper hardness (Shore A of 80 to 85), high-temperature resistance and high fire retarding resistance for wire and cable protective sleeves and insulation layers.

Description

technical field [0001] The invention relates to insulating plastics, in particular to a thermoplastic elastomer composition for cables and a preparation method thereof. Background technique [0002] Over the past two decades, elastomer halogen-free flame retardant systems have gradually entered the ranks of plastic research and have been accepted as a part of cable manufacturing technology. At present, there are a large number of suppliers of wire and cable materials in the world, and most of them are engaged in the development, development and production of halogen-free materials. Foreign companies that develop low-smoke, halogen-free and flame-retardant cable materials are relatively well-known companies such as American Carbon Union, PolyOne, Linders and Williams in the United Kingdom, Pandena Plastics in Italy, and Hitachi Electric Wire Co., Ltd. in Japan. clubs, etc. [0003] The development and industrialization of low-smoke halogen-free flame-retardant cable materia...
