SURFACE BLUSH-RESISTANT, FIRE-RETARDANT POLYOLEFIN RESIN COMPOSITION.

摘要

A surface blush-resistant and fire-retardant polyolefin resin comprises 100 pts. wt. of resin component contg. (a) polyolefin resin (99-60 wt.%) and (b) an olefin polymer modified with an unsatd. carboxylic acid or its deriv. 5-200 pts. wt. of a fire-retardant, and another component (d). Component (d) can be (1) mineral oil, wax or a paraffin, (2) a higher fatty acid or its ester, amide or metal salt, (3) silicone, (4) a polyhydric alcohol partially esterified with fatty acid, or an alkylene oxide adduct or aliphatic alcohol, fatty acid, aliphatic amine, fatty acid amide, alkylphenol or alkylnaphthanol, (5) a fluorinated elastomer. (a) is at least one ethylene copolymer selected from among ethylene-alpha-olefin copolymer, ethylene-vinyl ester copolymer and ethylene-unsatd. carboxylic acid (or its ester or metal salt) copolymer. The density of (b) is 0.86-0.97 g/cm3. (c) is an inorganic metal cpd. hydrate, such as Al(OH)3, Mg(OH)2 hydrates.
