Title: Resin compositions containing polyepoxides and uretdiones
IPC: H01B3/40
Filed: 1976-01-21
Abstract: 1492150 Epoxide resin composition HITACHI Ltd 21 Jan 1976 [7 Feb 1975] 02376/76 Heading C3B A resin composition having good storage stability comprises a polyepoxide having at least two vicinal epoxy groups; a uretdione compound having at least one uretdione ring in its structure and a tetraphenyl borateamine complex curing catalyst in sufficient amount, e.g. from 0À01 to 10 weight per cent of the total weight of the polyepoxide and uretdione compounds, for effecting the dissociation of the uretdione ring at a temperature above the melting point of the complex and for effecting reaction between isocyanate groups formed by the dissociation and between isocyanate groups and epoxy groups, thereby to form isocyanurate and oxazolidone rings in the cured resin of the composition. Suitable tetraphenyl borate complexes are those of aliphatic primary, secondary, tertiary and quaternary amines and of pyridines, imidazoles and morpholines having melting points within the range 100 to 300 C. and molecular weights of 350 to 1,000. The uretdione may be an isocyanate terminated compound having a molecular weight in the range 200 to 2,000 which is either a co-oligomer, e.g. an adduct of 2,4-tolylene diisocyanate and diphenyl methane-4,4<SP>1</SP> diisocyanate or is derived from a single aromatic polyisocyanate, e.g. 1,3- bis(3 - isocyanate - p - tolyl) 2,4 - uretdione. The uretdione and the polyepoxide, e.g. the diglycidyl ether of bisphenol A are used in an equivalent ratio of uretdione to polyepoxide of 0À8 to 4; the equivalent ratio being determined by the relationship between the number of isocyanate groups (including groups formed upon dissociation) of the uretdione and the number of epoxy groups in the polyepoxide. In a typical example 1,3-bis(3-isocyanate-ptolyl)2,4 uretdione and a polyglycidyl ether of a phenol-formaldehyde novolac resin mol. wt. 450 mixed in the equivalent ratio of 2 are kneaded on rolls for 10 mins. at 80 C. with triethylamine tetraphenyl borate, powdered glass and a mould release agent and the mixture crushed to give a powdered resin composition having a "pot life" of more than two months. The resin composition was moulded at 170 C. for 3 mins. under 100 p.s.i. pressure and then cured at 180 C. for 15 hours to produce a thermoset resin having good mechanical and electrical properties.
