Abstract

The invention provides an EVA composite material, an EVA composite clip net cloth prepared from the composite material, and a preparation method for the clip net cloth. The clip net cloth is used for producing ton-bags for encapsulation processing of various nuclear contaminations and nuclear wastes, anti-nuclear radiation tents, anti-seepage ton-bags, bearing bags, suitcase fabrics, life rafts and the like. The EVA composite material comprises the components of an ethylene vinyl acetate copolymer, rubber, polypropylene, polythene, an anti-oxidant, an ultraviolet light absorber, a photostabilizer, a peroxide crosslinking, a silane coupling agent, calcium stearate, titanium dioxide, calcium carbonate, talcum powder, mica powder, graphite and an organic dye.

Description

technical field [0001] The invention relates to an EVA composite material, an EVA composite sandwich cloth and a preparation method thereof, belonging to the field of polymer materials and preparation. technical background [0002] The sandwich cloth is a kind of textile mesh cloth as the base material, and one or more layers of plastic resin materials or plastic resin, rubber and other modified materials with different physical properties are compounded on both sides of the mesh cloth to achieve water resistance and air resistance. , Oxygen resistance, 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 120 degrees Celsius, low temperature resistanc...
