Изобретение относитс к способам химической обработки голь , в частности к дублению, и может быть использовано в кожевенной промышленности при выработке кож дл верха обуви.The invention relates to methods of chemical treatment of mole, in particular, to tanning, and can be used in the leather industry for making leather for shoe tops.
Цель изобретени - повышение термостойкости кож при сохранении их качества,The purpose of the invention is to increase the heat resistance of the skin while maintaining their quality,
Сущность изобретени заключаетс в том, что состав дл дублени кож, содержащий алюмокалиевые квасцы, хромпик, сульфит натри и воду, дополнительно содержит сополимер метил- акрилата, бутилакрилата и метакрило- вой кислоты при их массовом соотношении 62:35:3 (МБМ-3) и следующем соотношении компонентов состава, мас.%:The essence of the invention is that the composition for tanning leather, containing aluminum potassium alum, bromide, sodium sulfite and water, additionally contains a copolymer of methyl acrylate, butyl acrylate and methacryloic acid at a mass ratio of 62: 35: 3 (MBM-3) and the following ratio of components, wt.%:

Введение в состав сополимера метилакрилата , бутилакрилата и метакриловой кислоты создает услови дл образовани комплексных дуб щих соединений , содержащих также хром и алюминий . Такие соединени прочно св зываютс в структуре кожи, образу термостойкие поперечные св зи, Поэтому кожа, выдубленна предлагаемым составом, обладает высокой термостойкостью и не требует дополнительного дублени сол ми хрома.The introduction of methyl acrylate, butyl acrylate and methacrylic acid into the composition of the copolymer creates conditions for the formation of complex tanning compounds containing also chromium and aluminum. Such compounds firmly bind in the skin structure to form heat resistant crosslinks. Therefore, the skin that has been dug out by the proposed composition has a high heat resistance and does not require additional tanning with chromium salts.
