Embodiment 1

[0040] A degradable foamed slipper material with high starch content, prepared from the following raw materials in parts by weight: 55 parts of starch, 28 parts of EVA resin, 5 parts of modified plant fiber, 4 parts of reactive additives, and 2.5 parts of compatibilizer , 2 parts of blowing agent, 1.8 parts of hydrophobic auxiliary agent, 0.8 part of lubricant, 0.6 part of grafting auxiliary agent, 0.15 part of antibacterial agent, 0.15 part of antioxidant.

[0041] The slipper material is degradable, has high bio-based content, and has good mechanical strength, and the foamed slipper material has good resilience, and uses starch as the base material, which can significantly reduce costs. Compared with traditional EVA foam material, the cost can be reduced by 30%, with starch as the base material, the coloring is stable and uniform, and there is no obvious plastic taste.

Abstract

The invention belongs to the technical field of slipper materials, and particularly discloses a degradable foaming slipper material with high starch content and a preparation method thereof. The composite material is prepared from the following raw materials in parts by weight: 40-65 parts of starch, 15-45 parts of EVA resin, 2-6 parts of modified plant fibers, 3-8 parts of a reactive aid, 0.6-4 parts of a compatibilizer, 1-3 parts of a foaming agent, 0.8-2 parts of a hydrophobic aid, 0.4-1 part of a lubricant, 0.5-1.2 parts of a grafting aid, 0.1-0.5 part of an antibacterial agent and 0.1-0.5 part of an antioxidant. The slipper material is degradable, high in bio-based content and good in mechanical strength, the foaming slipper material is good in rebound resilience, starch is adopted as a base material, the cost can be remarkably reduced, compared with a traditional EVA foaming material, the cost can be reduced by 30%, the starch is adopted as the base material, coloring is stable and uniform, and no obvious plastic taste exists.

Description

technical field [0001] The invention relates to the technical field of slipper materials, in particular to a degradable foamed slipper material with high starch content and a preparation method thereof. Background technique [0002] At present, EVA foam slippers and TPR foam slippers have obvious cost competitive advantages, and they will seriously pollute the natural environment after being discarded. [0003] CN102226015A discloses a starch composite foaming material, and specifically discloses that the starch composite foaming material is composed of the following components by mass fraction: starch 1%-50%; EVA 10%-60%; elastomer 1%~50%; organic bentonite 0~5%; inorganic powder 0~50%; plasticizer 0.1%~15%; crosslinking agent 0.5~2%; composite foaming agent 2~11%; surface treatment agent 0~3%; compatibilizer 0~5%; other additives 0~5%; the elastomer is POE (ethylene octene copolymer), SEBS (styrene-ethylene / butylene-styrene copolymer) , ESI (ethylene-styrene copolymer), ...
