Definitions
- the present invention relates to an ethylene vinyl acetate-elastomer composite resin composition comprising a high expansibility ethylene vinyl acetate copolymer resin. More specifically, it relates to an ethylene vinyl acetate-elastomer composite resin composition having an expansion ratio of 50% or more using ethylene vinyl acetate having an expansion ratio of 80% or more using melt elasticity control.
- ethylene vinyl acetate copolymer the most representative cushion material for sports shoes, which plays a key part in the function of sports shoes, is easy to process at low temperatures, easy to crosslink, and has excellent foam cell formation. , as a functional sneaker material, is being continuously developed.
- thermoplastic elastomer may exhibit improved physical properties by combining the advantages of an ethylene vinyl acetate copolymer and a thermoplastic elastomer, but it is difficult to meet the expected physical properties when the two materials are simply mixed.
- the expansion rate must be high in a certain foam or thermal processing process such as foaming, but conventional ethylene vinyl acetate copolymer resins do not exhibit sufficient expansion properties.
- thermoplastic elastomer used together with the conventional ethylene vinyl acetate copolymer has low melt elasticity, so that the composite material mixed with the two components does not show sufficient foaming properties during the expansion process or during the foaming process, and the foaming properties are poor. Even if it appears, it is difficult to have a uniform cell structure, so there is a limit to its use.
- the expansion ratio of the composite material itself should be 50% or more, preferably 80% or more.
- An object of the present invention is to provide an ethylene vinyl acetate-elastomer composite resin composition having a high expansion ratio and forming a uniform foamed cell structure.
- Another object of the present invention is to provide an ethylene vinyl acetate-elastomer composite resin composition in which processability can be significantly improved when processed with a resin having a high melting point, such as a thermoplastic elastomer.
- an object of the present invention is to provide a high expansion ethylene vinyl acetate copolymer resin that is excellent in foamability and elasticity, and can provide a foam having a smooth surface.
- the present invention can provide an ethylene-vinyl acetate-elastomer composite resin composition with an expansion rate of 50% or more, which is prepared by including a thermoplastic elastomer in a high expansibility ethylene vinyl acetate copolymer resin having an expansion rate of 80% or more.
- the composite resin composition may include 1 to 100 parts by weight of the thermoplastic elastomer based on 100 parts by weight of the high expansibility ethylene vinyl acetate copolymer resin having the expansion coefficient of 80% or more.
- the expansion coefficient of the high expansibility ethylene vinyl acetate copolymer resin may include 100% or more.
- the expansion coefficient of the high expansibility ethylene vinyl acetate copolymer resin may include 130% or more.
- the ethylene vinyl acetate-elastomer composite resin composition may have an expansion rate of 50% or more.
- the ethylene vinyl acetate-elastomer composite resin composition may have an expansion rate of 80% or more.
- the high expansion ethylene vinyl acetate copolymer resin is prepared by modifying the ethylene vinyl acetate copolymer resin by any one method selected from thermal crosslinking, radiation crosslinking, X-ray crosslinking, and electron beam crosslinking.
