AI Technical Summary

Technical Problem

Traditional flame retardants release toxic gases during combustion, polluting the environment and cannot meet the environmental protection and safety requirements of modern industry. Existing nylon materials are flammable and release harmful gases during fire, threatening human health and the environment.

Method used

Iron nitrate and modified hydrotalcite are used as environmentally friendly flame retardants. By intercalation treatment and tannin modification of hydrotalcite, combined with branched nylon 6, a polymer nylon modified flame retardant plastic is prepared, and the use of The chelating catalytic carbonization of tannin acid improves flame retardant properties.

Benefits of technology

It has achieved excellent flame retardant properties and mechanical properties of polymer nylon modified flame retardant plastics, and its materials are environmentally friendly, non-toxic and smoke-resisting, meeting the requirements of modern industry for environmental protection and safety.

Abstract

The invention discloses environment-friendly macromolecular nylon modified flame-retardant plastic and a preparation method thereof, and relates to the technical field of plastic. The environment-friendly polymer nylon modified flame-retardant plastic prepared from the nylon 66, the branched nylon 6, the ABS resin, the flame-retardant modified hydrotalcite and the plasticizer is excellent in flame retardance. The hydrotalcite is subjected to intercalation treatment by using 3-aminophthalate, so that the interlayer spacing of the hydrotalcite is increased, the dispersity of the hydrotalcite is improved, meanwhile, the specific surface area of the hydrotalcite is increased, more active sites can react with tannic acid, more iron ions can be chelated, and the adsorption capacity of the hydrotalcite is improved. The flame-retardant property of the high-molecular nylon modified flame-retardant plastic is further improved. The tannic acid is used for further modifying the intercalated hydrotalcite, and then iron ions are chelated by using the chelating property of the tannic acid, so that a catalytic carbonization effect is achieved, and the flame retardant property of the macromolecular nylon modified flame-retardant plastic is enhanced.
