Description

Inorganic Carbonate Application Rubber Composition Manufacturing Method The present invention relates to a method for manufacturing a rubber composition with an inorganic carbonate, and more specifically, to a method for manufacturing a rubber composition with an inorganic carbonate that improves physical properties and durability by applying an inorganic carbonate to a rubber composition. Generally, rubber compositions are widely used in various industries and are essential for products requiring high physical properties and durability, particularly automobile tires, industrial belts, waterproof products, and electronic device components. Conventional rubber compositions consist mainly of mixtures of natural rubber (NR) and synthetic rubber (SBR, NBR, BR, etc.) and include fillers, vulcanizing agents, stabilizers, and other additives. These components play an important role in controlling the strength, elasticity, durability, and processability of the rubber. However, traditional rubber compositions have limitations in terms of physical properties and durability. In particular, carbon black or silica, which are conventionally used as fillers to enhance the abrasion resistance, tensile strength, and durability of rubber products, have certain limitations. As a result, rubber products may experience performance degradation or damage during continuous use, which consequently adversely affects product lifespan and reliability. Recent studies have highlighted the use of inorganic carbonates, particularly calcium carbonate and magnesium carbonate, as potential additives capable of improving the physical properties of rubber compositions. Inorganic carbonates possess excellent chemical stability and heat resistance, as well as eco-friendly characteristics, making them a safe and economical alternative to conventional additives. However, due to their inherent characteristics, inorganic carbonates are difficult to disperse uniformly within rubber compositions, and improper use can degrade the physical properties of the rubber. Therefore, to properly apply inorganic carbonates to rubber compositions, a technology is required to uniformly mix them and effectively bond them within the rubber structure. This allows for the maximization of the benefits of inorganic carbonates and enhances the tensile strength, wear resistance, and durability of the rubber. The present invention solves these problems and provides a manufacturing method that improves the performance of a rubber composition by utilizing inorganic carbonates. This method ensures that inorganic carbonates are uniformly dispersed within the rubber composition and presents a technical solution capable of improving durability and strength without degrading physical properties.
