Abstract

The invention discloses a teflon composite film for a protective garment. The teflon composite film comprises a teflon film layer and a PU coating. The PU coating comprises a bottom layer and an upper layer. The upper surface and the lower surface of the teflon film layer are coated with the bottom layer and the upper layer respectively. The teflon film layer comprises, by weight, 85-95 parts of polyflon, 5-8 parts of silicone powder, 2-4 parts of polyether ether ketone and 3.5-6.5 parts of lubricant. The PU coating comprises, by weight, 100 parts of PU resin, 10-15 parts of polyethylene wax, 5-10 parts of nanometer titania and 10-18 parts of N,N- nanometer titania. In this way, according to the teflon composite film for the protective garment, elasticity and protective performance of the film product are improved, the multiple functions of high temperature resisting, abrasion resisting, water resisting, moisture permeating, corrosion preventing and the like are achieved, and the teflon composite film is especially suitable for the protective garment used in a workplace where the working environment is severe.

Description

technical field [0001] The invention relates to a polytetrafluoroethylene composite film, in particular to a polytetrafluoroethylene composite film for protective clothing. Background technique [0002] PTFE film has many excellent functions such as windproof, feng shui, and moisture permeability. However, PTFE film lacks elasticity and poor wear resistance. If it is directly compounded in textile materials, it will affect its application effect with textile materials. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a polytetrafluoroethylene composite film for protective clothing of the present invention, which increases the elasticity and protection of film products, and has various properties such as high temperature resistance, wear resistance, waterproof, moisture permeability, and corrosion resistance. It is especially suitable for protective clothing in workplaces with harsh working environments. [0004]...
