Description

Изобретение относитс  к электротехнической промьдчпенности. .Известен расширитель дл  отрицательного электрода свинцового аккумул тора , состо вший из сульфата бари  и органической составл ющей десульфированной вйсокомолекул рной фракции смол.ванилинового производства 11 . В процессе циклировани  такой расширитель вымываетс  из эле :трода , кроме того, он способствует его разбуханию и не обеспечивает.стабил ные электрические характеристики электрода. Наиболее близким к изобретению по технической сущности и достигаемым результатам  вл етс  расширител . дл  отрицательного электрода свинцо вого аккумул тора, состо щий из сул фата бари  и органической составл ю щей на основе продукта конденсаций нафтолсульфоКислоты с фенолом и формальдегидом 12. Этот расширй .тель легко вымываетс  и не обеспечи вает требуемую емкость на начальных циклах из-за плохой адсорбции на свинце. С целью улучшени  адсорбции на свинце и уменьшени  вымываемости предложено в качестве органической составл юигей вз ть продукт глубокой поликонденсации 2-нафтолсульфокис. лоты с фенолом и .формальдегидрм при следуютем соотйошении компонентов , вес.%: : . Сульфат бари  36-70 Органическа  составл юща  30-64. Эта органичёсЛ а  .составл ю1ца  обладает крупной молекулой/ низкой таннйдностью и Милой вымываемостью, .хорошо сочетаетс  с ингибитором. Пример. Расширитель из 50 вес.% сульфата бари  и 50 вес.% органической сосТавл юшей - продукта глубокой поликонденсации 2-нафтолсульфокислоты с фенолом и формальдегидом был введен в отрицательный электрод и испытан в,свинцовой аккумул торной батарее типа 6 СТ-75. Дл  сравнени  в тех же услови х был испытан расииритель-прототип. Результаты испытаний приведены в таблице .This invention relates to the electrical industry. A extender for the negative electrode of a lead battery is known, consisting of barium sulphate and the organic component of a desulphurized high molecular weight fraction of vaniline resin production 11. During the cycling process, such an expander is washed away from the elec- trode, in addition, it contributes to its swelling and does not provide stable electric characteristics of the electrode. The closest to the invention to the technical essence and the achieved results is the extender. for a negative lead battery electrode, consisting of barium sulphate and an organic component based on the naphtholsulfo condensation product of acids with phenol and formaldehyde 12. This extension is easily leached and does not provide the required capacity during the initial cycles due to poor adsorption on lead. In order to improve the adsorption on lead and reduce leachability, it was proposed to take the product of deep polycondensation 2-naphtholsulfoxis as an organic compound. Lots with phenol and. Formaldehyde when followed by the following components, wt.%::. Barium sulphate 36-70 Organic content 30-64. This organic substance has a large molecule / low tannide and sweet washability. It is well combined with an inhibitor. Example. An expander made from 50 wt.% Barium sulphate and 50 wt.% Organic constituent - a product of deep polycondensation of 2-naphtholsulphonic acid with phenol and formaldehyde was introduced into the negative electrode and tested in a CT-75 lead battery. For comparison, a prototype prototype was tested under the same conditions. The test results are shown in the table.
