| 摘要 |
A flexible fabric suitable for weather protection purposes particularly adapted for example to covering agricultural grains in outdoor storage including a woven synthetic substrate with a melt extruded coating where the coating is a blend of an olefin copolymer and a high loading of an anhydrous, high density, insoluble, low toxicity inorganic filler. The high density filler is selected from abundantly available naturally occurring minerals having a specific gravity of 3.5 or more. Particularly suitable minerals may be non-hydrated forms of oxides, carbonates, sulphates and silicates of metals including aluminium, barium, iron, manganese, magnesium, titanium or zinc. A particularly suitable filler is barium sulphate. The high loading of inorganic filler involves inclusion of 10-20 % of the filler with respect to the mass of the coating. A suitable olefin copolymer is ethylene methyl acrylate copolymer or ethylene butyl acrylate copolymer. |
