Abstract

The invention discloses a preparation method of a polysulfone composite flame-retardant material. The preparation method comprises the following steps of 1, taking 65 parts by weight of polysulfone, and crushing the polysulfone into polysulfone particles having the diameter less than 5mm by a crusher, 2, uniformly mixing the polysulfone particles and 32 parts by weight of montmorillonite, and adding 3 parts by weight of aluminum hydroxide into the mixture, and 3, heating the mixture until partial fusion, and cooling to obtain the polysulfone composite flame-retardant material. Through utilization of montmorillonite in polysulfone, polysulfone flame retardation is effectively improved. Through utilization of aluminum hydroxide, composite material flame retardation is not influenced and can be improved. The preparation method is simple. The polysulfone composite flame-retardant material has a good flame retardation effect.

Description

technical field [0001] The invention relates to a preparation method of a flame-retardant material, in particular to a preparation method of a polysulfone composite flame-retardant material. Background technique [0002] In modern offices and homes, many materials are flammable. Due to the uncertainty of fire, when a fire occurs, many materials will burn. On the one hand, a lot of heat will be generated, and more importantly, many materials will emit toxic gases and smoke, which will increase the danger of fire. [0003] In order to reduce the hazards of fire, many flame retardant materials have been tested or used. However, many flame retardant materials currently face problems such as high cost, poor flame retardant effect, and low mechanical strength, which limit the application of flame retardant materials. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing a polysulfone composite flame-retardant material with ...
