preparation example Construction

[0048] Embodiments 1-6 disclose a preparation method of a halogen-free thermoplastic elastomer cable material, comprising the following steps:

[0049] (1) Fill the styrene-based thermoplastic elastomer with filler oil and let it stand for 15-20 minutes;

[0050] (2) Combine the styrene-based thermoplastic elastomer filled with oil in step (1) with polypropylene resin, compatibilizer, extender oil, toughening agent, ethylene-propylene rubber, halogen-free flame retardant, antioxidant, anti-oxidant Add the copper agent and lubricant into the high-speed mixer for mixing;

[0051] (3) adding the mixture obtained in step (2) to a banbury mixer;

[0052] (4) Feed the mixture mixed in the step (3) into a twin-screw extruder and cut it into pellets at 160-200° C. to obtain the halogen-free thermoplastic elastomer insulating material.

[0053] The raw material components of Examples 1-6 are shown in Table 1.

[0054] See Table 2 for the parts by weight of the raw material component...

Embodiment 7

[0060] Embodiment 7: The products obtained in Examples 1-6 were tested for performance, and the results are shown in Table 3.

[0061] Table 3: Performance testing results of Examples 1-6

[0062]

[0063] It can be seen from Table 3 that using hydrogenated SEBS as the base material has better performance than SBS base material in all aspects, using SEBS grafted maleic anhydride as compatibilizer, the overall performance improvement is more obvious; using metallocene polyolefin resin and poly The compound use of olefin elastomer is helpful to the tear resistance and elasticity of the material. Using non-PPO system, the processing temperature is low and the flame retardant level can also reach V0 level.

[0064] In summary, the halogen-free thermoplastic elastomer insulating material prepared by the present invention has excellent insulation and mechanical properties, low density, low hardness, and good scratch resistance; tensile strength and elongation at break are better ...

Abstract

The invention relates to a halogen-free thermoplastic elastomer insulating material and a preparation method thereof. The halogen-free thermoplastic elastomer insulating material comprises the following components: styrene thermoplastic elastomer, polypropylene resin, compatilizer, filling oil, ethylene propylene rubber, toughening agent, halogen-free flame retardant, antioxidant, copper resistantagent and lubricant. The preparation method comprises the following steps: 1) filling styrene thermoplastic elastomer with filling oil; 2) adding that oil and other components into a high-speed mixerfor mixing after the oil filling is completed; 3) adding that mixture into an internal mixer for internal mixing; 4) feeding the mixture after internal mixing into a twin-screw extruder to draw the strip and cut the grain at 160-200 DEG C. The halogen-free thermoplastic elastomer insulating material disclosed by the invention has low processing temperature, low hardness, superior insulation performance, high temperature resistance grade, scratch resistance, environmental protection, flame retardancy and excellent comprehensive performance, and is suitable for charging pile cables of electricvehicles.

Description

technical field [0001] The invention relates to a cable material, in particular to a halogen-free thermoplastic elastomer insulating material and a preparation method thereof. Background technique [0002] With the continuous maturity of new energy vehicle technology, major auto manufacturers at home and abroad have invested in the development and promotion of new energy charging vehicles. With the support of Chinese government policies, new energy vehicles have entered a stage of rapid development. The corresponding new energy vehicles The construction of supporting charging facilities is also the focus of national development. Under the trend of environmental protection, traditional polyvinyl chloride charging pile insulating materials have been gradually eliminated, and new environmentally friendly halogen-free thermoplastic elastomer charging pile insulating materials have been demanded by market development. [0003] After continuous improvement, various types of halog...
