Abstract

The invention relates to a thermoplastic polyether ester elastomer foaming material and a preparation method thereof. The foaming material is prepared from the following raw material components in parts by weight: 50 to 95 parts of polyether ester TPEE (Thermoplastic Polyether Ester Elastomer), 0 to 50 parts of a modified polymer material, 0.05 to 2 parts of a nucleating agent and 0.1 to 5 parts of a foaming agent; when the adding amount of the modified polymer material is 0, the difference (T2-T1) of the melting temperature T2 of the polyether ester TPEE and the Vicat softening point temperature T1 is greater than or equal to 30 DEG C. Compared with the prior art, a continuous foaming formula and a continuous foaming technology of the TPEE are provided, and the problems that the foaming material with stale performance is difficult to prepare by existing TPEE, especially continuous foaming is difficult to realize are solved.

Description

technical field [0001] The invention belongs to the technical field of polymer foaming materials, and relates to a preparation method of a thermoplastic polyether ester TPEE elastomer foaming material. Background technique [0002] Thermoplastic polymer elastic materials are widely used in various production and living facilities, equipment, tools and consumables. With the development of society, the demand for environmental protection, energy saving, consumption reduction, etc., the demand for lightweight materials has become more and more more urgent. Thermoplastic polymer elastic materials have also begun a large number of lightweight experiments and verifications and continued to promote their applications. For example, polypropylene PP foam, polyethylene PE foam, polystyrene PS foam, polyester PET foam, polyamide PA foam and polyurethane TPU foam, etc. The melt strength of thermoplastic polyetherester elastomer TPEE is low, and the polyester part of the skin of the me...
