AI Technical Summary

Problems solved by technology

The currently widely used flame retardants can be divided into halogen-containing and halogen-free flame retardant systems according to their composition. Among them, halogen-containing flame retardants release a large amount of smoke and toxic and corrosive gases during combustion, causing air pollution, hindering lifesaving and Escape; the large amount of metal hydroxide added in halogen-free flame retardants will affect other properties of the material; in addition, flame-retardant oligomers have good flame-retardant effects and low smoke and low toxicity, but the synthesis process is complicated and the cost is high

Abstract

The invention belongs to the technical field of novel materials and particularly relates to an FeAl3(PO4)4-SDS (sodium dodecyl sulfonate) fire retardant as well as a flame-retardant composite material employing the fire retardant and a preparation method for the fire retardant. The preparation method comprises the following steps: weighing Fe(NO3)3.9H2O and Al(NO3)3.9H2O in a ceramic mortar at a molar ratio, and finely grinding for uniformly mixing the two reagents; adding SDS, grinding, and standing; adding (NH3)H2PO4, grinding, and producing a standing reaction; finally, transferring an obtained reactant into a container, and baking the reactant in an oven to obtain the FeAl3(PO4)4-SDS fire retardant. A preparation process of the fire retardant is simple, the prepared polymer-flame-retardant composite material is relatively good in flame retardance and mechanical property, and the processing performance of the flame-retardant composite material cannot be influenced.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular to a FeAl 3 (PO 4 ) 4 -SDS flame retardant and its composite flame retardant material and preparation method using the flame retardant. Background technique [0002] High-molecular compounds are also called high-molecular polymers. Compared with low-molecular compounds, their molecular weights are very high. Due to this outstanding feature, it shows unique properties: high molecular weight, high elasticity, high viscosity, low crystallinity, and no gas. These characteristics also endow high-molecular materials (such as composite flame-retardant materials, rubber, etc.) with excellent characteristics such as high strength, high toughness, and high elasticity. So that it is widely used in electrical and electronic, structural construction, construction technology, vehicle manufacturing and other fields. Although they have good mechanical properties, processability and chemi...
