Abstract

The invention relates to tin salt hybridized melamine cyanurate and a preparation method and application thereof. In the process of synthesizing melamine cyanurate through melamine and cyanuric acid,metal ions and acid radical ions are introduced before a salt forming reaction, tin salt hybridized melamine cyanurate is prepared, a compound formed by combining the metal ions and the acid radical ions through ionic bonds is tin salt, the metal ions are tin ions or stannous ions, and the acid radical ions are cyanuric acid radical ions or phosphate anions or 2-carboxyethyl phenylphosphonic acidradical ions. Compared with melamine cyanurate, the temperature of prepared tin salt hybridized melamine cyanurate at the thermal weight loss of 5 wt% is improved by 10 DEG C to 50 DEG C, and the carbon yield at the temperature of 650 DEG C is increased by 10% or above, and tin salt hybridized melamine cyanurate can serve as a fire retardant and a smoke suppressant of a high polymer material. Themethod is simple and practicable, and prepared tin salt hybridized melamine cyanurate has a good flame retardant effect and smoke suppression effect.

Description

Technical field [0001] The invention belongs to the field of preparation and application of flame retardant smoke suppressants, and relates to a tin salt hybrid melamine cyanurate and a preparation method thereof. Background technique [0002] The flame retardant properties of polymer materials are generally poor, and the flame retardant properties are mainly obtained by adding flame retardants. The types of flame retardants include inorganic silicon flame retardants, graphite flame retardants, tin-containing flame retardants, organic halogen flame retardants, and melamine flame retardants. At present, the commonly used flame retardant is an organic halogen flame retardant. However, although it has good compatibility with organic polymers, good flame retardant effect, small addition amount, and small impact on other properties of the material, it is burning During the process, the amount of smoke is relatively large, and toxic and corrosive gases will be released, which will adv...
