Description
Изобретение относитей к области повышенн адгезии нитей из гюлиэтилентерефталата к резин&м на основе пол рных каучуков в процессе вулкаиизацни.The invention relates to the field of enhanced adhesion of filaments from H-ethylenterephthalate to rubbers & m based on polar rubbers in the process of vulcanization.
Известен способ модификации нити в процессе формовани волокна днснерсией диизоцпанатов , блокированных фенолом 1 и 2. существуют определенные трудности при приготовлении адгезионной препарации с указанным адгезивом ввиду его нерастворимости в воде. Кроме того, известно, что адгезионна способность полиэфиров, модифицированных изоцианатами, резко ухудшаетс во времени 3.There is a method of modifying the filament in the process of forming a fiber by dnsneric diisocanes, blocked with phenol 1 and 2. There are certain difficulties in preparing adhesive preparation with the specified adhesive due to its insolubility in water. In addition, it is known that the adhesion ability of polyesters modified with isocyanates sharply deteriorates over time 3.
При использовапин водных растворов адгезивов дл полиэфирных нитей по вл етс реальна возможность модификации полиэфирных ннтей с целью улучшепн адгезии в про-, дессе получени волокна.When used with aqueous solutions of adhesives for polyester yarns, there is a real possibility of modifying polyester nnty in order to improve adhesion in pro-fiber production.
Известен способ обработги полиэфирной нити, включающий пропптку растворов поливинилового снирта, латекспорезорцпнформальдегидмым составом и термообработку . Однако такой способ не обеспечивает достаточной адгезии полиэфирной нити к резппе.A known method of processing polyester yarn, including propptku solutions of polyvinyl tape, latexporezorpnformaldehym composition and heat treatment. However, this method does not provide sufficient adhesion of the polyester yarn to the rezppe.
С целью повышени адгезии к резине по предлагаемому способу нмть иосле пропитки полпвиипловым спиртом дополнительно ироиптыкают насыщенным раствором KHS04 и термообрабат;,.вают в кпп;-пш;м гептане нIn order to increase the adhesion to rubber according to the proposed method, after impregnation with semi-alcohol with alcohol and additionally with a saturated solution of KHS04 and heat treatment, heat dissolve in a check point;
Tcneniie 1-4 час или на воздухе 2 мин при 220-С.Tcneniie 1-4 hours or in air for 2 minutes at 220-C.
По предлагаемому способу иолнвпииловый снирт нанос т в виде 0,5-10%-ного раствораAccording to the proposed method, a molded coating is applied in the form of a 0.5-10% solution
на нить. Нить с поверхностной пленкой из полпвинилового сппрта (ПВС) подвергают обработке раствором KHSO4 и термообрабатывают . Затем провод т обработку латекснорезорцинформальдегидным составом с последующей сущкой при повышениой температуре. Модифицированную таким образом нить можно обработать 2%-ным водным раствором брома дл галогенированп дегидратированной пленки ПВС на поверхности нити ири 20°С вon the thread. The filament with a surface film of polvovinilovogo sppre (PVA) is subjected to treatment with a solution of KHSO4 and thermoablative. A lateral resorcinol formaldehyde composition is then carried out, followed by drying with an increase in temperature. The filament thus modified can be treated with a 2% aqueous solution of bromine for a halogenated dehydrated PVA film on the surface of the ir thread 20 ° C in
