INTRODUCTION
Organic Montmorillonite (OMMT), with its unique layered structure and multifunctionality after modification, shows great potential in material science, especially in the field of flame retardants.K100, developed by YINSU Flame Retardant Company, as a kind of OMMT, significantly improves the flame retardant and mechanical properties of the material through specific organic modification technology. mechanical properties.
Research on Organochemical Modification of Montmorillonite
Researchers at YINSU Flame Retardant Company have reported a study on the organic modification of montmorillonite. In this study, organochemical montmorillonite was prepared by ion exchange reaction using quaternary ammonium salt (CTAB) as an intercalating agent. The influence of process parameters such as modifier dosage, reaction time, reaction temperature and pH on the modification effect of montmorillonite was investigated in detail, and the modified samples were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR).
Key points of the modification technology
1. Dosage of intercalation agent: It was found that the optimal dosage of CTAB was 20% of the weight of montmorillonite, in which the ion exchange reaction between montmorillonite and CTAB was the most adequate, which was favorable for the insertion of organic chain segments.
2. Reaction temperature: The experiment shows that the organic modification effect of montmorillonite is best under the reaction temperature of 80℃, which not only ensures the reaction, but also avoids the side reaction that may be caused by too high temperature.
3. reaction time: the optimization of the reaction time found that a reaction time of 2 hours was sufficient for effective ion exchange between CTAB and montmorillonite to form organic montmorillonite.
4. pH value: The effect of pH value on the modification effect is relatively small, but under acidic conditions (pH 3-5), the modification effect is better, so a pH value of 5 was chosen as the optimal condition.
5. Characterization results: By XRD analysis, the crystal spacing of the modified montmorillonite increased from 1.25 nm to 1.93 nm, which proved that the CTAB molecules were successfully inserted into the interlayer of the montmorillonite and enhanced its lipophilicity, thus improving the compatibility with the polymer.
Application Prospects
As a kind of nano-organic montmorillonite developed by YINSU Flame Retardant Company, K100 shows great potential in improving the flame retardancy, mechanical properties and thermal stability of polymers. Through the above modification technology, the application scope of K100 is expected to be further expanded, including but not limited to:
1. Enhancement of polymer matrix: The addition of K100 can significantly improve the mechanical properties of polymers, such as tensile strength and tear strength.
2. Improved thermal stability: K100 modified polymers have higher thermal stability and lower heat release rates.
3. Improved flame retardancy: K100, as a highly effective flame retardant, can effectively reduce the heat release rate and smoke release rate of the material.
Conclusion
YINSU Flame Retardant's K100 organo-montmorillonite represents a major advancement in materials science in the field of flame retardants. By precisely controlling the modification conditions, K100 has demonstrated excellent performance enhancement. With in-depth research and expanding applications, K100 has the potential to become an important player in the field of flame retardant materials in the future, contributing to the safety and environmental protection of the society.
