POLYOLEFIN COMPOSITION, METHOD OF METALLIC SURFACE COVERING AND METALLIC TUBE |
摘要 |
chemical technology. SUBSTANCE: invention relates to technology of preparing polyolefin compositions filled with hole microspheres and used for covering metallic surfaces by welding torch spraying. Composition has, wt. %: (1) from 1 to 40 hole microspheres; (2) from 60 to 99 of the parent polyolefin composition containing: (a) from 25 to 95 of polypropylene, polyethylene or crystalline copolymers of propylene or their mixtures; (b) from 0.01 to 70 of elastomeric copolymer; (c) from 0.5 to 10 of polypropylene or polyethylene modified with polar groups; (d) from 0.01 to 10 of titanium dioxide. EFFECT: improved physical-mechanical properties of covers on metallic tubes, simplified equipment using. 9 cl, 1 tbl, 4 ex
