Rubber foam composition having a high tensile strength and high elongation and a processe for the preparation of ruber foam using thereof

摘要

The present invention relates to a high-strength and high elongation rubber foam composition, a rubber foam using the same and a method for manufacturing the same, and more particularly to a high viscosity rubber-based resin as a resin composition to solve low tensile strength and elongation, which is a major disadvantage of the rubber foam And functional elastomer, mixed with appropriate crosslinking agent and foaming agent, and manufactured by chemical crosslinking or photocrosslinking method, which significantly lowers breakage, airtightness, and consequent deterioration of thermal insulation, and is widely used in various fields such as construction, construction, transportation, and sports. It relates to a rubber foam composition of high strength and high elongation, which is suitable for use, a rubber foam using the same and a method for producing the same. The rubber foam composition prepared according to the present invention can lower the linear crosslinking rate and induce proper crosslinking foaming, thereby using a good cell structure and having an excellent closed cell structure while maintaining a proper foaming rate, flame retardancy, tensile strength and elongation rate. It can be used to produce this significantly increased rubber foam. Therefore, the rubber foam composition having a high strength and high elongation according to the present invention is a heat insulating material, a sound insulation material, a structural material, a toy material, an auxiliary material in a wide range of fields such as various construction, construction, transportation (car, railway, ship), sports, other industrial products, etc. It can be used as a heat insulating material, a sound insulation material, a structural material, etc. in wide field | areas, such as these.
