Abstract

The invention discloses a preparation method of a fabric with high chemical protection performance. According to the invention, a PTFE film and a PPS fabric are subjected to hot-pressing compounding at 80 DEG C, a polymer modified film coated on the surface of the PPS fabric is fused at the temperature, the PTFE film and the polymer modified film are entangled among molecules at high temperature and are transferred along with the molecules, and finally, high-temperature hot-pressing compounding of two interfaces of PTFE and PPS is achieved, so that a skeleton layer is obtained; the polytetrafluoroethylene (PTFE) film is excellent in acid and alkali resistance, so that the PTFE film is selected to coat the surface of the PPS fabric, the prepared fabric has higher acid and alkali corrosion resistance, meanwhile, the polyhalogenated olefin film is selected as a barrier layer material of the chemical protection fabric, the film is compact in structure and excellent in chemical stability, and due to the fact that the film contains halogen elements, the film is nonflammable, and the chemical protection fabric has the advantages of being high in acid and alkali corrosion resistance. The combustion characteristic is carbonization, and no molten drops occur. When the film is used as a barrier layer of the chemical protection fabric, the chemical protection capability of the whole fabric is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of protective fabrics, in particular to a preparation method of highly chemically protective fabrics. Background technique [0002] Chemical protection refers to the protective measures taken by the military against chemical weapons attacks. Organized and implemented by commanders at all levels and headquarters. The purpose is to avoid or reduce injuries, maintain the combat effectiveness of troops and the freedom of combat operations, professional support units and mass protection organizations. It is an important content of combat support. Chemical protection was developed in the fight against chemical weapons attacks. To correctly choose chemical protective clothing, understanding the penetration or penetration of various chemical substances is a necessary prerequisite for the protected fabric. [0003] However, in the use of common fabrics, the protective performance of the fabrics is relatively gene...
