Description
Повышение водостойкости и износоустойчивости кожи и колоных деталей путем пропитки их дисперси ми синтетических высокополимеров , например полиизобутилена, известно. При этом дл растворени или диспергировани последних обычно примен ют такие летучие органические растворители, как бензин , бензол и т. п., что усложн ет и удорожает технологический процесс , ввиду необходимости в последующем удалени растворител из пропитанной кожи и рекуперации его.Increasing the water resistance and durability of the skin and colony parts by impregnating them with dispersions of synthetic high polymers, for example polyisobutylene, is known. In addition, volatile organic solvents such as gasoline, benzene, etc., are usually used to dissolve or disperse the latter, which complicates and increases the cost of the process, due to the need for subsequent removal of the solvent from the impregnated skin and its recovery.
С целью устранени этих недостатков , предлагаетс способ обработки кож и кожаных деталей гидрофобизирующими растворами или дисперси ми вышеуказанных высокополимеров, заключающийс 3 том, что в качестве растворител (или диспергатора) последних примен ют твердые углеводороды, например высокоплавкий парафин.In order to eliminate these drawbacks, a method for treating leather and leather parts with hydrophobic solutions or dispersions of the above high polymers is proposed, consisting in the fact that solid hydrocarbons, such as high melting paraffin, are used as a solvent (or dispersant).
Пример. Подвещенную деталь из рыхлого топографического участка воротка с влагосодсржанием 10-12% погружают в раствор полиизобутилена (молекул рный вес- 40000) в высокоплавком парафине. Температура раствора 70-90°, продолжительность сквозной пропитки - несколько минут. Дл устранени налета на ,поверх ности пропитанной детали, ее дополнительно прогревают в термостате или под инфракрасным облучателем. В результате , прочность детали на истирание (на стандартном приборе УКРПИКП) возрастает на 40-50% .Example. A substitute detail from the loose topographic section of the crank with a moisture holding of 10-12% is immersed in a solution of polyisobutylene (molecular weight of 40,000) in high-melting paraffin. The temperature of the solution is 70-90 °, the duration of through impregnation is several minutes. To eliminate plaque on the surface of the impregnated part, it is additionally heated in a thermostat or under an infrared illuminator. As a result, the strength of parts for abrasion (on a standard device UKRPIKP) increases by 40-50%.
