As a type of polymer material that can maintain excellent performance under extremely high temperature environments, the selection and ratio of its chemical composition are crucial. This type of resin is usually based on a variety of complex and fine chemical substances and is made through a specific synthesis process to meet the requirements of refractory materials for high strength, high hardness, high thermal stability and chemical inertness.Among the chemical components of liquid resins, the most common are polymer skeletons based on phenolic resins, epoxy resins, polyurethane resins, etc. These resins are usually made through polycondensation reactions or addition polymerization reactions, have a three-dimensional structure, and can form a stable cross-linked network during the curing process, thereby giving refractory materials excellent mechanical strength and heat resistance.As an important component of refractory matter liquid resin, phenolic resin is mainly made of phenol and formaldehyde. Under the action of a catalyst, phenol and formaldehyde form phenolic resin through polycondensation reactions. This resin has excellent heat resistance, chemical corrosion resistance and high mechanical strength. In refractory materials, phenolic resin is not only used as a binder, but also can effectively improve the overall performance of the material due to its unique chemical structure.Epoxy resin is another commonly used refractory matter liquid resin. The synthetic raw materials of epoxy resin include bisphenol A, epichlorohydrin, etc., which are obtained by polycondensation reaction. Epoxy resin has excellent adhesion, chemical corrosion resistance and mechanical strength, and the cured product has good thermal stability and electrical insulation properties. In refractory materials, epoxy resin is often used to improve the toughness and impact resistance of materials.Polyurethane resin, with its unique elasticity and wear resistance, is also widely used in refractory materials. The synthetic raw materials of polyurethane resin include polyols, isocyanates, etc., which are obtained by addition polymerization reaction. In refractory materials, polyurethane resin is not only used as a binder, but also can effectively improve the crack resistance and wear resistance of the material.In addition to the above-mentioned base resins, various functional fillers and additives may be added to refractory matter liquid resin, such as inorganic fillers such as graphite powder, porcelain powder, quartz powder, and organic additives such as curing agents, catalysts, and diluents. The selection and proportion of these fillers and additives have an important impact on the performance of refractory materials. For example, graphite powder can improve the thermal conductivity and electrical conductivity of the material; porcelain powder and quartz powder can enhance the hardness and wear resistance of the material; curing agents and catalysts can accelerate the curing process of the resin and improve production efficiency.In summary, the chemical composition of refractory matter liquid resin is complex and delicate, and the selection and proportion of various raw materials have been strictly considered and optimized. These resins not only provide excellent physical and chemical properties for refractory materials, but also promote the continuous development and innovation of the refractory industry.
