Example Embodiment

[0055] Example

[0056] The present invention will be further described below in conjunction with specific embodiments. However, these examples are only for illustrative purposes, and are not used to limit the protection scope of the present invention.

[0057] The polyetherester elastomer copolymer and various stabilizers were blended and granulated in proportion in the TSSJ-25 twin-screw extruder of Sichuan Chenguang Plastic Machinery Research Institute, and were granulated in accordance with ISO37 on the CJ80E injection molding machine of Guangdong Zhende Plastic Machinery Factory Standard production of tensile spline, visual inspection of the surface after aging in an aging oven, if it has cracked, then no tensile performance test, if the surface is intact, the tensile performance test is done on the CMT4202 tensile machine of Shenzhen Xinsansi Test Equipment Factory.

[0058] Observe whether the appearance of the product is deformed and cracked after 180℃ / 3 hours;

[0059] Obser...

Example Embodiment

[0068] Example 1:

[0069] By changing the combination of stabilizers, the effect on the heat resistance of HP3511 was investigated.

[0070] Table I

[0071]

[0072] NA: Surface cracking, no test

[0073] It can be seen from Table 1 that when the Irganox 1098 / DSTP / Naugard445 stabilizer combination is used, the heat-resistant stability effect of the product is obvious.

[0074] Experiment 2

[0075] By changing the combination of stabilizers, the impact on the heat resistance of HP4701 was investigated.

[0076] Table II

[0077]

[0078] NA: Surface cracking, no test

[0079] It can be seen from Table 2 that when a single stabilizer is used, the thermal stabilization effect is poor, and the product is deformed or cracked, which does not meet the requirements. When the phenol and thiosulfate stabilizers are combined, they have good effects, the product has no deformation and cracking phenomenon, and the retention rate of tensile strength is 65.3%, but it still does not reach the retention...

Abstract

The invention provides a high temperature resisting thermoplastic polyether ester elastomer composition, which comprises a thermoplastic polyether ester elastomer copolymer and a heat stabilizer composition. The heat stabilizer composition comprises a phenolic heat stabilizer, a sulpho-ester stabilizer and an aromatic amine stabilizer. The heat stability of the thermoplastic polyether ester elastomer composition is improved remarkably, and the thermoplastic polyether ester elastomer composition has good dyeing property.

Description

technical field [0001] The invention relates to a thermoplastic polyether ester elastomer composition and a preparation method thereof, in particular to a white thermoplastic polyether ester elastomer composition with good thermal stability and a preparation method thereof. Background technique [0002] As an engineering grade elastomer, thermoplastic polyether ester elastomer has excellent physical and mechanical properties, such as high strength, high toughness, fatigue resistance, abrasion resistance, oil resistance, chlorine resistance, good electrical properties and low temperature resistance Therefore, it has been continuously used in various aspects in recent years. However, due to the existence of a large number of ether bonds in thermoplastic polyetherester elastomers, it is easy to oxidatively degrade, resulting in poor high temperature thermal stability, which limits its application in some high-end fields. For example, for wires and cables with a temperature res...
