Abstract

The invention discloses an isobornyl acrylamide phosphorus-containing phenanthrene oxide, its preparation method and its application. The structural formula of the isobornyl acrylamide phosphorus-containing phenanthrene oxide is as follows: The present invention isobornyl acrylamide phosphorus-containing Phenanthrene oxide has excellent flame retardancy enhancement performance, and isobornyl acrylamide containing Phosphophenanthrene oxide, and then blended with polyols, isobornyl acrylamide-containing phosphophenanthrene oxides can be dissolved in polyols, and then reacted with polyols and isocyanates to obtain flame retardant and excellent mechanical properties Rigid polyurethane foam.

Description

technical field [0001] The invention relates to an isobornyl acrylamide phosphorus-containing phenanthrene oxide, a preparation method and an application thereof, and belongs to the field of flame-retardant reinforcing materials. Background technique [0002] Polyurethane (PU) is a kind of polymer containing urethane characteristic units in the main chain. Rigid polyurethane foams are widely used in household appliances and construction materials because of their good mechanical properties, low apparent density, and thermal conductivity. However, due to the porous structure and high specific surface area of ​​rigid polyurethane foam, the foam is easy to catch fire, the flame spreads quickly, has high flammability, and has a great fire hazard. In addition, the decomposition of rigid polyurethane foam during combustion will release a large amount of toxic gases (such as CO and HCN), while generating unbearable heat and suffocating smoke, which may cause serious fire accidents...
