| 简介 |
The group of inventions relates to binders for polymeric composite materials, more particularly for materials for outer space applications, and to methods for producing same. Proposed is a method for producing a composition of melt binders based on metal chelates and oligocyanurate resins with reactive cyanate groups for impregnating reinforcing material in polymer composite materials for outer space applications, wherein a resin is heated to a molten state, a catalyst, consisting of metal chelates in the form of dry powder with a particle size of 40-125 µm, is introduced into the melt produced, the amount of catalyst added being 50-600 ppm based on the ratio of metal ion mass to the total weight of the composition, and the melt is then mixed to a visually uniform state. The composition for impregnating reinforcing material in polymer composite materials for outer space applications produced by the proposed method is in the form of a solution or melt comprising 50-600 ppm of complex compounds or mixtures thereof comprising ions of aluminium, transition metals and rare-earth elements with various organic ligands in resins having reactive cyanate groups, and is solvent- or diluent-free. |
