TABLE 1 PC/ABS materials Performance test results
As can be seen from Table 1, the modified BDP flame retardant prepared by adding the carboxyl-terminated hyperbranched polyester modified nano-silica particles into the BDP flame retardant is beneficial to improving the toughness and the flame retardance of the material, improving the precipitation property of the material, this is probably because the nano-silica after surface treatment has improved compatibility with resin matrix, and is helpful for dispersing nano-particles, and more importantly, the nano-particles after surface treatment have some reactive groups, in the process of mixing with BDP liquid, the modified nano silicon dioxide is riveted on a BDP molecular chain to form a plurality of cross-linked networks taking the modified nano silicon dioxide as a core, in the process of mixing with the plastic melt, the defects of flame retardance, toughness reduction and precipitation degree increase caused by BDP dispersion unevenness due to large viscosity difference between BDP and the melt in the processing process are greatly improved; in addition, the modified nanoparticles are riveted with the molecular chain of the BDP and the molecular chain of the PC resin during the mixing process, so that the activity of the low-molecular flame retardant in a high-temperature and high-humidity environment is limited, and the precipitation degree of the BDP flame retardant is reduced. If the addition amount of the modified nano silicon dioxide is too small, the density of a cross-linked network is insufficient, the riveting effect is insufficient, the dispersity is also poor, the addition amount is too large, the riveting effect is too strong, the reaction is too violent, and the maintenance of the toughness of the material is not facilitated.
