AI Technical Summary
Technical Problem
In the prior art, microfibrillated cellulose does not have flame retardancy, and when inorganic compound flame retardants are added, large amounts need to be added and they are not easy to disperse evenly. The flame retardancy of anionic modified microfibrillated cellulose has not been fully utilized.
Method used
By converting the anionic groups of anionicly modified microfibrillated cellulose into metal salts, metal ions are introduced to form flame-retardant coatings and sheets, thereby improving the coatability and film strength of the coating.
Benefits of technology
It achieves highly efficient flame retardancy of microfibrillated cellulose, improves the coatability and film strength of the coating agent, and eliminates the need for additional flame retardants.
