摘要/Abstract

摘要：

为进一步扩展聚酰胺6织物的应用领域,采用磺胺作为阻燃整理剂,在高温条件下,通过浸渍沉积法对聚酰胺6织物进行阻燃防熔滴整理。并对整理后聚酰胺6织物的热稳定性、热释放性能、抗熔滴性能、阻燃性能和阻燃机制进行分析。结果表明:经磺胺阻燃整理后,聚酰胺6织物的极限氧指数达到32.2%,损毁长度和损毁面积均减小,无熔滴产生,达到阻燃B₁级的要求,具有较好的阻燃效果;同时整理后聚酰胺6织物的最大热释放速率下降了16.9%,火灾危害性显著降低;磺胺主要通过气相阻燃机制提高聚酰胺6织物的阻燃性能,且阻燃整理对聚酰胺6织物的强力和手感影响较小。

关键词: 聚酰胺织物, 磺胺, 阻燃整理, 抗熔滴, 气相机制

Abstract:

In order to further expand the application field of polyamide 6(PA6) fabric, sulfanilamide was used as flame retardant agent to finish polyamide 6 fabrics by impregnation deposition at high temperature. The thermal stability, heat release ability, melt dripping performance, flame retardant property and mechanism of the treated PA6 fabric were investigated. The results showed that the treated PA6 fabric had a high LOI value of 32.2%, and the damaged length and area were reduced without dripping phenomenon, suggesting that the treated PA6 fabric reached the B₁ classification with good flame retardant performance. Meanwhile, the peak heat release rate of the treated PA6 fabric decreased by 16.9%, indicating significant decrease of fire hazard. It was suggested that sulfanilamide improved the flame retardancy of PA6 fabric mainly through the gas-phase mechanism. The flame retardant treatment exerted little influence on the tensile strength and handle of the treated PA6 fabric.

Key words: polyamide fabric, sulfanilamide, flame retardant modification, anti-dripping, gas-phase mechanism
