Abstract

The invention discloses aphosphaphenanthrene-containing isobornyl acrylamide oxide, and a preparation method and application thereof. The structural formula of thephosphaphenanthrene-containing isobornyl acrylamide oxide is shown in the specification, the phosphaphenanthrene-containing isobornyl acrylamide oxide has excellent flame-retardant enhancement performance. N-isobornyl acrylamide reacts with 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide to obtain the phosphaphenanthrene-containing isobornyl acrylamide oxide, then the phosphaphenanthrene-containing isobornyl acrylamide oxide is blended with polyhydric alcohol, and is dissolved in the polyhydric alcohol, and then the polyhydric alcohol reacts with isocyanate to prepare rigid polyurethane foam with good flame retardant property and excellent mechanical property.

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...
