Description
Изобретение относится к резиновой •промышленности, в частности к способу крепления полиэфирного волокна к резине.The invention relates to the rubber industry, • in particular, to the method of attaching polyester fiber to rubber.
Известен способ крепления полиэфирного волокна к резине пропиткой волокна раствором производного диоксибензола, например продукта реакции резорцина и галоидного аллила, сушкой, термообработкой латексным рёэорцинформальдегидным составом, обкладкой резиновой смесью с последующей вулканизацией. £ΐ] .There is a method of attaching polyester fiber to rubber by impregnating the fiber with a solution of a dioxibenzene derivative, for example, a reaction product of resorcinol and allyl halide, drying, heat treatment with a latex Ryoorcin formaldehyde composition, lining with a rubber mixture, followed by vulcanization. £ ΐ].
Однако этот способ крепления не обеспечивает необходимой адгезии волокна к резине, кроме того, он сложен в технологическом отношении (пропиточный раствор имеет сложный состав и требует высокой температуры термообработки 150-250°С ) .However, this method of attachment does not provide the necessary adhesion of the fiber to rubber, in addition, it is technologically difficult (the impregnating solution has a complex composition and requires a high heat treatment temperature of 150-250 ° C).

Цель изобретения состоит в повышении адгезии волокна к резине и снижении температуры термообработки.The purpose of the invention is to increase the adhesion of the fiber to rubber and lowering the temperature of heat treatment.
Поставленная цель достигается 25The goal is reached 25
проведением пропитки водным раствором аллилгидрохинона с концентрацией 2-3 вес.% до привеса после сушки 1-2% от волокна и термообработкой при 130140°С в течение 2-6 мин.impregnation with an aqueous solution of allylhydroquinone with a concentration of 2-3 wt.% to gain after drying 1-2% of the fiber and heat treatment at 130140 ° C for 2-6 minutes.
Пример 1. Полиэфирное волокно (полиэтилентерефталатное) выдерживают в 3%-ном водном растворе аллилгидрохинона в течение 10 с при комнатной температуре, после чего его нагревают при 135°С в течение 46 мин. Привес волокна составляет 1,5%. Затем модифицированное волокно обрабатывают стандартным пропиточным латексным реэорцинформальдегидным составом на основе смолы ФР-12 и латекса бутадиенового каучука СКД-1 с последующей термообработкой при 130140йС в течение 4 мин. После обкладки резиновой смесью и вулканизации прочность связи волокна с резиной в 1,5-1.,8 раза выше по сарвнению с известным способом. Величина разрывной прочности волокна полиэтилентерефталата после пропитки и термообработки при указанных температурах не снижается.Example 1. Polyester fiber (polyethylene terephthalate) is kept in a 3% aqueous solution of allylhydroquinone for 10 s at room temperature, after which it is heated at 135 ° C for 46 min. Fiber weight gain is 1.5%. Then, the modified fiber is treated with the standard impregnating latex composition reeortsinformaldegidnym resin DF-12 and SKD butadiene rubber latex-1, followed by heat treatment at 130 140 nd C for 4 min. After lining with rubber compound and vulcanization, the bond strength of the fiber with rubber is 1.5-1., 8 times higher in comparison with the known method. The value of the tensile strength of polyethylene terephthalate fiber after impregnation and heat treatment at the indicated temperatures does not decrease.
Пример 2. Процесс ведут аналогично примеру 1 с использованием водного раствора аллилгидрохинона концентрации 2 вес.% до привеса 2% от волокна.Example 2. The process is carried out analogously to example 1 using an aqueous solution of allylhydroquinone concentration of 2 wt.% Up to a gain of 2% from the fiber.
Результаты аналогичны примеру 1.The results are similar to example 1.
33
Итак, предложенный ^пособ обеспечивает высокую адгезию полиэфирного волокна к резине (в 1,5-1,8 раза выше известного).So, the proposed guide provides high adhesion of polyester fiber to rubber (1.5-1.8 times higher than the known).
