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.
