Abstract

The invention relates to a composition for foaming material with high rebound resilience and a preparation method thereof. The composition is prepared from the following components in parts by weight: 5 to 95 parts of alkene polymer, 5 to 95 parts of TPU (thermoplastic polyurethane) elastomer, 0.1 to 45 parts of compatilizer, 0.1 to 10 parts of foaming agent, 0.01 to 5 parts of crosslinking agent, 0 to 5 parts of crosslinking additive, and 0 to 10 parts of other additive. The composition has the advantages that by utilizing the comptilzier with polarity groups or double active groups, the interface tension between the alkene polymer and TPU is reduced, an alkene polymer/TPU IPN (inter-penetrating polymer network) structure is formed, and the problem of compatibility between two types of materials is solved; by successfully introducing the TPU component into the alkene polymer, the excellent resilience of TPU is utilized, and the rebound resilience, compression permanent deformation and the like of the alkene polymer are greatly improved.

Description

technical field [0001] The invention relates to a composition for high-resilience foaming materials and a preparation method thereof, belonging to the field of lightweight materials. Background technique [0002] Olefin polymer foaming materials (such as EVA, SEBS, POE, etc.) have good softness, rubber-like elasticity, good flexibility below 0°C, good chemical stability, anti-aging and With good ozone strength, it is widely used in foamed shoe materials, luggage linings, toy materials, sporting goods materials, building materials, and various emerging applications including electronic accessories and automotive interiors. [0003] However, high expansion ratio olefin polymer foaming materials have poor resilience, large permanent deformation, serious decline in mechanical properties, and poor wear resistance, which greatly reduces their performance and seriously affects their application range. Thereby, develop a kind of high resilience, and can keep the olefinic polymer / TP...
