Description

Method for Neoprene Conjugation The present invention relates to a method for manufacturing neoprene laminates, and more specifically, to a method for manufacturing neoprene laminates that effectively combines neoprene with fabrics, films, and other synthetic materials to provide high-quality laminates with enhanced water resistance, durability, thermal insulation, and aesthetic elements. Generally, neoprene is a synthetic rubber based on chlorinated polychloroprene that is widely used in various industrial fields because it provides excellent elasticity and durability while possessing waterproof, windproof, and thermal insulation properties. Typically, neoprene is used in products such as suits, sports protective equipment, waterproof bags, and various industrial pads. Conventional methods for manufacturing neoprene laminates have primarily consisted of two approaches. The first method involves bonding a neoprene sheet with other materials using an adhesive. While this method can provide high bonding strength, it presents drawbacks. For example, if the adhesive is applied unevenly, bonding strength may decrease at certain joints, or the laminate may separate due to adhesive degradation over long-term use. Additionally, there are disadvantages such as increased manufacturing costs as adhesive usage increases, and potential environmental issues. The second method involves bonding neoprene sheets with other materials using thermal bonding. Thermal bonding is a process that bonds materials by applying high temperature and pressure without the need for separate adhesives, offering the advantages of being simpler and more economical than adhesive-based methods. However, conventional thermal bonding methods had limitations in ensuring bond quality, as the difference in thermal conductivity between neoprene and other materials resulted in uneven bond strength or deformation of the materials themselves due to the heat. To solve these problems, the present invention aims to provide a manufacturing method that provides a more stable and uniform bond when combining neoprene with other materials.
