Description

Применение консистентных смазок , содержащих в качестве антикоррозийной присадки бензоат натри , ограничено, так как водные растворы бензоата натри , представл ющие собой соли слабой кислоты и сильного основани , имеют сильно щелочную реакцию и вызывают коррозию изделий из цинка, алюмини , меди и др. металлов.The use of greases containing sodium benzoate as an anticorrosive additive is limited because aqueous solutions of sodium benzoate, which are salts of a weak acid and a strong base, are highly alkaline and corrosive to products made from zinc, aluminum, copper and other metals.

Предлагаемое изобретение позвол ет устранить корродирующее действие бензоата натри  путем введени  в смазки смеси бензоата натри  и бензойной кислоты, имеющей рН 7, в количестве не менее 0,2%. Предложенна  присадка оказывает защитное антикоррозионноеThe present invention eliminates the corrosive effect of sodium benzoate by introducing into the lubricant a mixture of sodium benzoate and benzoic acid having a pH of 7 in an amount of at least 0.2%. The proposed additive has a protective anti-corrosion.

действие как на черные, так и на цветные металлы.action on both ferrous and non-ferrous metals.

Claims (2)

1.Сиособ приготовлени  на ос-, нове бензоата натри  противокоррозийной присадки к смазкам, отличающийс  тем, что, с целью защиты от коррозии изделий как из черных, так и из цветных металлов , присадку готов т в виде водного раствора из смеси бензоата натри  и бензойной кислоты, вз тых в количествах, обеспечивающих нейтральность присадки, т. е. рН 7.1. A method for preparing sodium nitrate benzoate based on an anticorrosive lubricant additive, characterized in that, in order to protect products from ferrous and non-ferrous metals from corrosion, the additive is prepared as an aqueous solution from a mixture of sodium benzoate and benzoic acids taken in amounts that ensure the neutrality of the additive, i.e. pH 7. 2.Прием выполнени  способа по п. I. отличающийс  тем, что присадку добавл ют к смазке в количестве не менее 0,2%.2. A method according to claim 1, wherein the additive is added to the lubricant in an amount of at least 0.2%.
