The invention discloses a kind of large-scale oil sac water pocket TPU composite materials, and it from top to bottom includes polyester-type TPU face mask layers, the first glue adhesive layer, scrim cloth and the second glue adhesive layer, polyether-type TPU bottom membranes successively, and the scrim cloth passes through sided corona treatment.The present invention is modified to polyester-type TPU materials, using film made of two kinds of material mixed polyester type TPU of ethylene propylene diene rubber and polycarbodiimide, there is stronger oil resistivity and anti-hydrolytic performance simultaneously, with reference to polyether-type TPU film, so that the fabric oil resistivity and anti-hydrolytic performance that are combined further enhance, combined again with PUR PURs after carrying out electric roller processing to fiber cloth simultaneously, enhance the peel strength of composite material, so that composite material good combination property, can be used for making oil sac or water pocket. |
