Abstract

The invention provides an EVA (ethylene-vinyl acetate) foamed elastic material and application thereof. The elastic material is prepared by mixing and foaming the following components in percentage by weight: 30-50% of EVA copolymer, 10-30% of ethylene-octylene copolymer, 5-15% of additional thermoplastic elastomer, 10-30% of flame retardant, 1-9% of foaming agent, 0-1% of foaming promoter, 1-2% of bridging agent and 0-2% of antimicrobial agent. The elastic material provided by the invention has shape memory function and slow-rebound performance, and can be used for pillows, mattresses, automobile mats and the like in household or medical recovery care products.

Description

technical field [0001] The invention relates to an elastic material, in particular to an EVA foamed elastic material and its application. Background technique [0002] Most of the cushion materials on the market are made of polyurethane-based foam. The known soft and rigid polyurethane-based foam cushions are usually made of a mixture of polyols and isocyanates, and finally capped with ethylene oxide (EO). For example, the Chinese patent CN101781454B provides a low-hardness polyurethane elastomer composition, which adopts a two-component system and consists of a prepolymer and a polymer component. The prepolymer is obtained by reacting dibasic methane diisocyanate and polypropylene oxide ether polyol The prepolymer of isocyanate, the polymer component is prepared from polypropylene oxide ether polyol, catalyst and antiaging agent. [0003] However, this kind of foam material is relatively soft. After being made into products such as seat cushions, it cannot always provide a...
