| titleOfInvention | High-strength epoxide composition and preparation method thereof |
| abstract | FIELD: chemistry. n SUBSTANCE: invention refers to the high-strength epoxide composition used for impregnation at production of high-strength glass-, carbon,- organic-, and boron plastics working in the wide temperature range and used in different industrial sectors (machinery construction, shipbuilding, aircraft and space industries, for production of the parts of complicated configuration e.g. thin- and thick-walled casings). The invention refers also to the method for preparation of the said composition including the following components (weight parts): 10-100 - diglycidyl resorcinol ether, 10-100 - product of epichlorohydrin condensation with triphenol, 6-12 - oligoether cyclocarbonates with mass ratio of cyclocarbonate groups in the range from 18 to 29, 28-50 - curing agent (primary aromatic amine), 0.5-2.5 - curing agent (tertiary amine), 0.25-1.25 - mixture of carbon and silicate nanomaterials. The mass ratio of diglycidyl resorcinol ether to product of epichlorohydrin condensation with triphenol is in the range from 1 : 9 to 9 : 1. Metaphenylen diamine or 4,4'-diaminodiphenylmethane or their eutectic mixtures in ratio from 40 : 60 to 60 : 40 are used as primary aromatic amine. Mono-, di and trimethylsubstituted pyridine or monovinylsubstituted pyridine are used as tertiary aromatic amine. The carbon nanomaterial is fullerene C 2n , wherein n is no less than 30, the silicate nanomaterial is organobentonite, the fullerene : organobentonite ratio is in the range from 1 : 3 to 3 : 1. The method of composition preparation consists in stirring of nanomaterials mixture with oligoether cyclocarbonates by ultrasonic action at frequency 22-44 kHz during 30-45 min. Then the obtained suspension is mixed with beforehand prepared mixture of diglycidyl resorcinol ether and product of epichlorohydrin condensation with triphenol. After that the curing agent in the form of aromatic primary and tertiary amine mixture is added. The ready composition is cured in step mode with maximal curing temperature 155°C. n EFFECT: invention allows obtaining of the composition with high physical, mechanical and dissipative properties. n 2 cl, 2 tbl, 6 ex |
