TPU composite material, TPU composite laminated fabric and preparing method of TPU composite laminated fabric

Abstract

The invention provides TPU composite laminated fabric and a preparing method of the TPU composite laminated fabric. The TPU composite laminated fabric is used for manufacturing various packaging and treatment ton bags for nuclear pollutants and nuclear waste, anti-nuclear-radiation shielding materials, anti-seepage ton bags, high-weight object bearing bags, case materials, life rafts and the like. The TPU composite laminated fabric comprises a TPU coating layer, a unimolecule coating, base cloth, a unimolecule coating and a TPU coating layer, wherein the TPU coating layer, the unimolecule coating, the base cloth, the unimolecule coating and the TPU coating layer are connected in sequence from top to bottom, and each TPU coating layer comprises thermoplastics type polyurethane, rubber, high molecular weight polyethylene, an antioxygen, an ultraviolet light absorber, a light stabilizer, a peroxide crosslinking agent, a silane coupling agent, calcium stearate, titanium dioxide, calcium carbonate, rare earth, talcum powder, mica powder and organic dyestuff.

Description

technical field

[0001] The invention relates to a TPU composite material, a TPU-type composite sandwich cloth and a preparation method thereof, belonging to the field of polymer materials and preparation. technical background

[0002] Sandwich cloth is a kind of textile mesh cloth as the base material, and one or more layers of plastic resin materials with different physical properties or modified materials such as plastic resin and rubber are compounded on both sides of the mesh cloth. In order to achieve water resistance, gas resistance, oxygen resistance, and weather resistance (GB / T16422.2 for 2500 hours, the performance is not lower than 80% of the original). UV resistance: (UVA-340, 0.77w / m 2 at310nm, the intensity after 1500 hours of irradiation is not lower than 70% of the original intensity). Resistance to nuclear radiation: (at 10 10 mGy (rad) radiation dose remains stable). Corrosion resistance, high temperature resistance 100 degrees Celsius, low temperature ...
