摘要
为改善硅酸盐类无机胶的性能,将改性纳米蒙脱土(MMT)引入硅酸钠Na2SiO3基胶黏剂中,用于压制胶合板。对胶合板的胶合强度、燃烧性能及胶黏剂热稳定性的检测结果表明:MMT改性Na2SiO3胶的干胶合强度和热稳定性增强;制备胶合板的阻燃性能增强。
In order to improve bond strength and fire retardant of inorganic adhesive based on sodium silicate for plywood manufacturing,modified nano-montmorillonite (MMT) was added to the adhesive.The results showed that MMT could improve bond strength and fire retardant of the plywood considerably.Thermal stability of inorganic adhesive increased.Compared with the control samples,the total heat release (THR),total smoke production (TSP),heat release rate (HRR) and CO production rate (COP) of the plywood also decreased.
