In modern industry, advancements in materials science play a crucial role in driving social progress. Styrene-Butadiene Rubber (SBR) and thermosetting resins (BT) are two important materials widely used in various fields. With the development of technology, effectively combining these two materials to achieve better performance has become a hot research topic. This paper aims to explore the preparation methods, performance characteristics, and practical applications of SBR-modified thermosetting resins (hereafter referred to as BT resin).

I. Preparation Methods of SBR-Modified BT Resin

SBR is a synthetic rubber known for its excellent elasticity, wear resistance, and oil resistance. BT resin, on the other hand, is a thermosetting plastic with superior mechanical strength and chemical stability. Combining these two materials requires a specific chemical reaction. A common method involves free radical polymerization, where initiators break the macromolecular chains in SBR, generating new free radicals. These radicals then copolymerize with monomers in BT resin, ultimately producing the modified BT resin.

II. Performance Characteristics of SBR-Modified BT Resin

1. Enhanced Physical Properties The tensile strength and compressive strength of BT resin are improved after SBR modification. This is because the introduction of SBR increases the material's toughness, enabling BT resin to withstand external forces better without fracturing. Additionally, the hardness of BT resin is enhanced by SBR, making it more suitable for manufacturing wear-resistant and impact-resistant components.

2. Improved Chemical Stability The incorporation of SBR significantly enhances the chemical stability of BT resin. Due to SBR's excellent oxidation resistance, it effectively prevents oxidative degradation of BT resin under high-temperature conditions, thereby extending the material's service life.

3. Better Processing Performance SBR-modified BT resin exhibits improved fluidity and plasticity during processing. The addition of SBR reduces the viscosity of BT resin, making it easier to handle during molding and processing. This also reduces the risk of material deformation or cracking caused by excessive processing temperatures.

III. Application Fields of SBR-Modified BT Resin

1. Automotive Manufacturing Due to its higher mechanical strength and better chemical stability, SBR-modified BT resin is widely used in automotive components such as engine parts and transmission system parts. These components require high strength, wear resistance, heat resistance, and corrosion resistance.

2. Electronics and Electrical Industry In the electronics and electrical field, SBR-modified BT resin can be used to manufacture various electronic components, such as circuit boards and connectors. These products demand good electrical and mechanical properties to ensure stable operation of electronic devices.

3. Construction Industry In construction, SBR-modified BT resin is employed to manufacture building materials like doors, windows, flooring, and ceilings. These materials require excellent weather resistance and aging resistance to ensure the longevity of buildings.

SBR-modified thermosetting resin (BT resin) is a high-performance composite material. Through appropriate preparation methods, the advantages of SBR and BT resin can be effectively combined, developing materials with superior comprehensive properties. With the continuous advancement of technology, it is believed that more applications of SBR-modified BT resin will emerge in the future, providing stronger technical support for the development of various industries.
