| titleOfInvention | Binding compound for cold-curing mould and core sand |
| abstract | The invention relates to a foundry and can be used to make casting molds and cores from cold-hardening resin mixtures. The purpose of the invention is to increase the strength of rods and molds in the initial stages of curing and improve sanitary and hygienic working conditions. The binding composition contains May. %: carbamidofuran resin 73-84; VAT residue of periodic distillation of caprolactam 1-2; acidic waste from the production of monochloramine 15-25. The introduction of the periodic distillation of caprolactam and the acidic waste from the production of monochloramine to the composition of the binding composition of the bottoms residue allows modification of the furan resin, increasing its pH, which makes it possible to use highly concentrated p-chlorobenzenesulfonic acid. 3 tab.
