COMPOSICAO DE RESINA RESISTENTE AO IMPACTO E CORPO DE CAIXA DE REFRIGERADOR |
摘要 |
<p>An impact-resistant resin composition comprising a graft polymer (in which an aromatic alkenyl compound and an alkenyl cyanide compound are grafted onto a rubbery polymer) and a matrix (comprising a copolymer of an aromatic alkenyl compound and an alkenyl cyanide compound) can have improved vacuum-formability and the moulded articles prepared by vacuum-forming the composition can have smaller variations in thickness from point to point and a smaller reduction in strength due to contact with foamed polyurethane by ensuring that the following conditions are met:… (a) the proportion of rubber polymer in the composition is from 10 to 30% by weight;… (b) the graft polymer has a degree of grafting of from 70 to 120% by weight;… (c) the matrix has an intrinsic viscosity of from 0.55 to 0.80 dl/g, measured at 30 DEG C in methyl ethyl ketone; and… (d) the weight ratio of the aromatic alkenyl compound to the alkenyl cyanide compound in the composition is from 2.0 : 1 to 2.8 : 1. …<??>Incorporation in the composition of from 0.01 to 2% by weight of a diorganopolysiloxane having a viscosity of from 5 to 100,000 centistokes at 25 DEG C and/or from 0.1 to 3% by weight of a metal salt of a fatty acid improves the ability of the composition to maintain its strength upon contact with foamed polyurethane. The resulting composition is of value in forming the box body of a refrigerator.</p> |
