Investigation of Preparation and Performance of Flame-retardant Coated Paper
摘要
Abstract
In this study,the aqueous flame-retardant coating was prepared derived from the film-forming of soluble starch,and the flame-re-tardant additive of ammonium sulfate and ammonium dihydrogen phosphate.Then,the flame-retardant coating was coated on the surface of paper with a basis weight of 60 g/m2.When the mass ratio of starch,ammonium sulfate,and ammonium dihydrogen phosphate was 3∶1∶2,the content of flame-retardant additive of the coating was 5%,and the coating amount was 2.0 g/m²,the damage ratio of the flame-retardant coated paper in the vertical combustion test decreased from 100%of the raw paper to 35.9%,and the limiting oxygen index increased from 18.3%to 30.0%.The acids produced by the decomposition of flame-retardant additive exerted catalytic carbonization for cellulose and starch,and the non-flammable gas caused by the decomposition of nitrogen-containing groups diluted the combustibles and oxygen.Conse-quently,the flame-retardant coated paper was endowed excellent flame-retardant performance.Besides,the tear strength of the flame-retar-dant paper 4#was increased from 308 mN for raw paper to 339 mN,and the tensile strength was well retained.关键词
