Flame retardant polyurethane microporous membrane preparation and the performance testing

摘要

Take liquid phase separation method to prepare polyurethane microporous membrane. In the preparation of microporous membrane process phosphorus add modification flame retardant agent in order to improve the polyurethane flame retardant properties. Experiments prove that the add of flame retardant can increase the flame retardant performance of polyurethane greatly when phosphorus add quantity of flame retardant agent for 8% polyurethane microporous membrane flame retardant was the best effect. And microporous membrane other performance also have no obvious effect. Because of flame retardant performance was good, this kind of polyurethane can be widely used in floor synthetic leather, wall paper, decoration, etc.
