Method for obtaining antipyrenes for plastics and polymeric compositions with limited combustibility

摘要

the application relates to how to receive antypirenu plastics, especially polypropylene. the application also relates to polymer compositions containing antypiren. way to receive antypirenu plastics, characterised by the fact that leads to synthesis of intensively stirring water dispersion containing 5 to 20% by weight. melamine, 10 to 70 wt%. polifosforanu ammonium, 10 - 40 wt%.pentaerythritol, 0.5 - 5% by weight. cynianu zinc, 5 to 20% by weight. acid cyjanurowego, initially by 0.5 - 2 hours at room temperature, followed by 3 - 6 hours at a temperature not exceeding 90u00b0c, what shall be the finished product by the evaporation of water and dried in high temperature under reduced pressure.
