Embodiment 1

[0023] The concrete substance and mass fraction thereof of each component selected in this embodiment are as follows:

[0024] (1) base oil is neutral mineral oil, and its mass fraction is 86.5%;

[0025] (2) The barium-free rust inhibitor includes two kinds of calcium dinonylnaphthalene sulfonate and oxidized wax calcium soap, the mass fractions of which are 5% and 5% respectively;

[0026] (3) The thixotropic agent is hydrogenated castor oil, and its mass fraction is 1%;

[0027] (4) auxiliary agent is imidazoline, and its mass fraction is 2%;

[0028] (5) The antioxidant is 2,6-di-tert-butyl-4-cresol, and its mass fraction is 0.5%.

[0029] When making, first put the base oil into the reaction kettle for heating and stirring, then put in the barium-free rust inhibitor, heat and stir to 100-120°C for dehydration, and add thixotropic agent, additives and antioxidants when it is cooled to below 80°C. After stirring, the finished product is obtained after 1μ filtration.

Embodiment 2

[0031] The concrete substance and mass fraction thereof of each component selected in this embodiment are as follows:

Abstract

The invention discloses an environment-friendly thixotropic antirust oil which is composed of base oil, barium-free antirusting agent, thixotropic agent, accessory ingredient and antioxygen. The manufacturing method comprises the following steps: pouring the base oil with a weight of 73-96% into a reaction kettle to be heated and stirred; then pouring, heating and stirring barium-free antirusting agent with a weight of 2-20% to 100-120 DEG C before carrying out dehydration; adding thixotropic agent with a weight of 0.5-5.0%, antioxygen with a weight of 0.1-5.0% when cooling the mixture to below 80 DEG C; then carrying out 1 mu filtration to obtain the finished product. The antirust oil features excellent antirusting property and cleanable property and a certain degree of lubricity. A certain degree of calendering operation can be satisfied without the user adding lubricating agent. With excellent thixotropy, stable oil film can be formed on metal skin, flow can be reduced, oil comsumption can be saved, operating environment can be improved and environment-friendliness can be ensured.

Description

Technical field: [0001] The invention relates to a production method of thixotropic antirust oil. Background technique: [0002] At present, anti-rust oils on the market use barium-containing anti-rust oils. Barium is a heavy metal that has an impact on the environment, soil, and human health. At present, European and American countries have promulgated regulations on barium-containing articles, and its use is strictly prohibited. Therefore, in order to protect the environment, a barium-free antirust oil is developed, and a barium-free antirust agent is used as a composition of the antirust oil. [0003] In addition, the steel plate anti-rust oil used by many steel mills is sprayed on the surface of the steel plate and rolled up for storage. Due to the influence of rolling tension and extrusion, a lot of oil is accumulated at the bottom of the steel coil, causing pollution to the ground and the transportation environment. Invention content: [0004] The purpose of the p...
