Problems solved by technology

At present, foreign merchants who provide such lubricants mainly include Rhodia and Condat companies in France, Zeller+Gmelin companies in Germany, etc., but their prices are very expensive, about 20,000 to 30,000 yuan per ton, resulting in the production of radial tire steel cords. The cost of the product has increased significantly, which is not conducive to the market competition of the product

Embodiment Construction

[0009] Describe the preparation method of radial tire steel cord drawing lubricant of the present invention in further detail below in conjunction with specific embodiment:

[0010] 1) Take 9kg of chlorinated paraffin and 9kg of triethanolamine soap and put them into the reaction kettle, stir and heat up to about 145°C, make them thoroughly mixed and ready for use.

[0011] 2) Put 10kg of polyethylene wax, 2kg of sodium benzoate, 5kg of fatty alcohol polyoxyethylene ether, 4kg of benzotriazole, 15kg of sodium soap, and 46kg of soft water into the reaction kettle, stir and heat up to about 85°C to make it Mix thoroughly and set aside.

[0012] 3) Mix and stir the mixture obtained in the above step 1) and step 2) to make it fully emulsified, then cool to normal temperature, filter to remove impurities, and the obtained milky white homogeneous liquid is the radial tire steel cord of the present invention Finished drawing lubricant.

[0013] The lubricant prepared above is used ...

Abstract

The lubricant consists of polyethylene wax, paraffin chloride, triethanolamine, sodium benzoate, fatty alcohol-polyoxyethyleneether, benzotriazole, sodium soap and water in certain proportion. The preparation process includes the following steps: mixing homogeneously paraffin chloride and triethanolamine while heating to 140-150 deg.c; mixing homogeneously polyethylene wax, sodium benzoate, fattyalcohol-polyoxyethyleneether, benzotriazole, sodium soap and water while heating to 80-90 deg.c; mixing the two kinds of mixture in the foregoing steps, emulsifying, cooling and filtering to obtain ivory white liquid as the product. The lubricant ensures complete coating on the steel cord thread, increases the adhesion between the steel card thread and rubber, and has no corrosion to pipeline andapparatus and low cost.

Description

technical field [0001] The invention relates to a metal wire drawing lubricant and its preparation technology, in particular to a radial tire steel cord drawing lubricant and a preparation method thereof. Background technique [0002] With the rapid development of my country's automobile industry and high-grade highways, the demand for automobile tires is increasing rapidly, and the performance requirements for automobile tires are also getting higher and higher. The huge demand in the automobile tire market has directly stimulated the tremendous development of the production of radial tire steel cords, and the drawing lubricant used in the production of radial tire steel cords is extremely critical to the quality and cost of radial tire steel cords. effect. At present, there are no more than two types of metal drawing lubricants produced in China: one is a synthetic fatty acid lubricant, and the other is a solid particle lubricant. On the one hand, t...
