NANOCOMPOSITE OF UNSATURATED POLYESTER RESIN AND CLAY AND SHEET MOLDING COMPOUND COMPOSITION CONTAINING THE NANOCOMPOSITE

摘要

PURPOSE: A nanocomposite of an unsaturated polyester resin and clay, a sheet molding compound composition containing the nanocomposite and a container for an aircraft unit loading container prepared by using the composition are provided to improve the lightweight of the container without deterioration of the strength. CONSTITUTION: The nanocomposite comprises 100 parts by weight of an unsaturated polyester resin; and 2-10 parts by weight of clay modified organic-friendly by being mixed with an organic modifier. Preferably the organic modifier is selected from the group consisting of dimethylbenzyl hydrogenated-tallow ammonium, dimethyl hydrogenated-tallow (2-ethylhexyl)ammonium, methyl tallow bis-2-hydroxyethylammonium and dimethyl dihydrogenated-tallow ammonium. The composition comprises 100 parts by weight of the unsaturated polyester resin; 2-10 parts by weight of clay modified by the organic modifier; 0.5-2.0 parts by weight of a curing agent; and 30-300 parts by weight of a filler.
