Problems solved by technology

[0003] At present, the TPE material based on SEBS, while improving the flame retardancy by adding a large amount of organic flame retardants, is easy to scratch white, easy to precipitate, low mechanical properties, poor resilience, poor weather resistance and fatigue resistance, etc.
The reduction of these comprehensive properties affects the service life and operational safety of the product, and limits the application of low-smoke, halogen-free and flame-retardant TPE materials in the field of electronic and electrical connecting wires, especially the materials for new energy charging pile cables.

preparation example Construction

[0041] The invention also discloses a preparation method of the flame-retardant TPE sheath material, which specifically comprises the following steps:

[0042] (1) After stirring SEBS and filling oil at low speed for 1 to 3 minutes according to the formula ratio, let it stand for use;

[0043] (2) Add raw material POE, polypropylene, organic flame retardant, flame retardant synergist, anti-scratch agent, antioxidant and processing aid to the silo, and set the program according to the proportion of raw material components, and automatically After batching and mixing, melt extrusion and granulation, and finally the flame retardant TPE sheath material is obtained.

[0044] In order to further realize the technical effect of the present invention, the melt extrusion granulation process in step (2) is specifically as follows: the raw materials are added to the twin-screw extruder through an automatic weight loss weighing scale for melting and mixing, and then extruded through a sin...

Abstract

The invention discloses a flame-retardant TPE sheath material, and a preparation method and an application thereof, and belongs to the technical field of halogen-free flame-retardant materials. The flame-retardant TPE sheath material is prepared from, by weight, 25-30 parts of SEBS, 8-12 parts of POE, 8-12 parts of polypropylene, 20-30 parts of an organic flame retardant, 5-10 parts of a flame retardant synergist, 3-5 parts of a scratch-resistant agent, 0.1-0.3 part of an antioxidant, 10-15 parts of filling oil, 1-3 parts of a processing aid, and the balance of deionized water. The TPE sheathmaterial developed in the invention has the characteristics of high flame retardant property, scratch resistance, no precipitation, high weather resistance, good mechanical properties, stress fatigueresistance, weather aging resistance and other excellent properties, can effectively solve the contradiction between flame retardancy and physical and mechanical properties in the existing halogen-free flame-retardant TPE sheath materials, can be well used as a new energy electric vehicle charging pile cable material, and has great market application and promotion values.

Description

technical field [0001] The invention relates to the technical field of halogen-free flame retardant materials, in particular to a flame retardant TPE sheath material and a preparation method and application thereof. Background technique [0002] Thermoplastic elastomer TPE not only has the high elasticity, high strength and high resilience of rubber, but also has excellent colorability, weather resistance, fatigue resistance and temperature resistance, and is environmentally friendly, non-toxic and safe, with a wide range of hardness, which can be recycled to reduce cost. With the increasing awareness of environmental protection in the whole society, the relevant environmental protection regulations such as EU RoHS standards and REACH regulations have been gradually implemented in the electronic and electrical fields, and the demand for green and environmentally friendly thermoplastic materials is increasing. Halogen-free flame retardant cable material has become the focus ...
