Embodiment 1

[0019] Example 1: The expansion ratio is about 136%; the hardness is about 67.

[0020] Such as figure 1 As shown, weigh and take the composition in Table 1 to prepare and mix uniformly, then mold and foam, and the foamed test piece is tested for related physical properties.

Embodiment 2

[0025] The application formula of Example 2, the expansion ratio is about 150% and the hardness is about 38:

[0026] Such as figure 1 As shown, weighed according to the combination formula in Table 3, prepared and mixed uniformly, then molded and foamed, and the foamed test pieces were tested for related physical properties.

Abstract

The invention discloses a composition of a novel polymer material hyperbranched hydrogenated elastic polystyrene substituted for ethylene-vinyl acetate copolymer, which can maintain the advantages of low density and light weight of the product and simultaneously have high anti-slip and low compression deformation application characteristics. The composition of the present invention is calculated in parts by weight, and it includes: polymer hyperbranched hydrogenated elastic polystyrene 50-100 phr; filler 5-20 phr; cooling agent 1-5 phr; processing aid 1-3 phr; bridging agent 0.5 ~1.2phr; bridging aid 0.5~2phr; blowing agent 1~3phr; After uniform mixing and kneading, a composition with low density, high resilience and high slip resistance is prepared. The invention can be applied to the field of polymer foaming materials.

Description

technical field [0001] The invention relates to the field of polymer foaming materials, in particular to a composition with low density, high resilience and high anti-slip properties and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is a polymer material, which is widely used in various foaming materials, such as shoe soles, insoles, floor mats, toys, life jackets and various thermal insulation materials. This material has many application advantages, such as: good cushioning and shock resistance, good heat insulation effect, good moisture resistance and no water absorption, can meet the needs of product appearance, low density can be used for lightweight applications, etc. In addition to the above advantages, the material itself also has some relatively weak characteristics, such as: poor performance on product compression deformation, and poor anti-slip effect. If the application product has relevant requirements for co...
