Problems solved by technology

In the traditional process, nylon fibers are reinforced by mixing ultra-high molecular weight polyethylene and nylon during spinning and then melt spinning, but this method will reduce the hardness, tensile strength and elongation of the composite, and This method needs to use more ultra-high molecular weight polyethylene fibers to strengthen the material, and the increase in cost is not conducive to production

Abstract

The invention belongs to the technical field of materials, and specifically relates to a high-intensity fabric film composition and a preparation method thereof. The composition comprises the following components: a low-melting-point TPU surface film layer, a PU surface adhering layer, a polyethylene fiber reinforced nylon based fabric layer, a PU bottom adhering layer and a low-melting-point TPUbottom film layer. The preparation method comprises the following steps: drying ultrahigh molecular weight polyethylene fiber reinforced nylon base fabric; coating with glue; then adhering with the TPU film which is extruded by using a casting film machine; then performing mirror counter-pressing, cooling, shearing and pressure-increase coiling to obtain the high-intensity fabric film composition.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a high-strength fabric film compound and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane (TPU) is a high molecular polymer with excellent properties. According to the structure, it can be divided into two types: polyester type and polyether type. TPU has good oil and water resistance, chemical corrosion resistance, antibacterial properties, abrasion resistance, tensile strength, and elongation at break. TPU has incomparable advantages over other polymers in medical, food, clothing, sports and other fields. [0003] In order to obtain a fabric film composite with excellent mechanical properties, ultra-high molecular weight polyethylene fibers can be used without considering the cost, but the ultra-high molecular weight is relatively expensive, and the bonding effect with the TPU film is not good. At the same time, the processi...
