Abstract

The invention provides a flame-retardant polyethylene fabric with ultrahigh molecular weight and a preparation method thereof. The method comprises the following steps: firstly, carrying out a two-leaching and two-mangling process on a polyethylene fabric with ultrahigh molecular weight in a fire retardant solution for a polymer, which has the mass percent of 20%-30%, wherein the mangle expression is 70%; drying at 60 DEG C for 15min and drying the fabric; carrying out single-face or double-face coating on the surface of the fabric by utilizing a polyvinylidene fluoride solution with the mass percent of 10%-20%, and controlling the thickness of the coating to be 0.5mm-2mm; and drying the coating fabric at a drying temperature of 60 DEG C-85 DEG C to prepare the flame-retardant polyethylene fabric with the ultrahigh molecular weight. The oxygen index of the flame-retardant polyethylene fabric with the ultrahigh molecular weight is more than 27; the flame-retardant polyethylene fabric can be rapidly self-extinguished when leaving away from fire; meanwhile, the flame-retardant polyethylene fabric has flame-retardant, high-strength and non-ventilation performances; and the process method is simple, and industrial implementation is easy to realize. The fabric can be used for high-strength, flame-retardant and non-ventilation conditions in the fields of military affairs or terrorism prevention and the like.

Description

Technical field [0001] The invention relates to a flame-retardant fabric and a preparation technology thereof, in particular to a flame-retardant ultra-high molecular weight polyethylene fabric and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene fiber is the third generation of high-strength, high-modulus, high-tech special fiber after carbon fiber and aramid fiber. Due to its extremely high molecular mass, good combination of the molecular backbone, high crystallinity and orientation of the fiber, and excellent tensile properties of the fiber, its tensile strength is currently the existing industrialized high-performance fiber. The highest, the specific strength is equivalent to 15 times that of high-quality steel wire, 2.6 times that of carbon fiber, and 1.7 times that of aramid. In addition, it also has excellent weather resistance, chemical corrosion resistance, sea water resistance, impact resistance, fatigue resistance, ...
