Embodiment 1

[0023] The present embodiment prepares environment-friendly cold heading oil according to the following steps:

[0024] First, weigh 45g of epoxidized soybean oil (the kinematic viscosity at 40°C is 34mm 2 / s). Add to the blending kettle, then add 20g of trimethylolpropane fatty acid ester, 10g of chlorinated paraffin S-52, 15g of sulfurized lard, 4g of sulfur-containing extreme pressure agent RC2540, 1g of oily phosphoric acid Esters, warmed up slightly to 55°C, stirred for 30min; then added a mixture of 1g of sodium petroleum sulfonate and 1g of benzotriazole, 0.8g of benzisothiazolinone and 0.2g of 3-iodo-2- The mixture of propynyl butyl carbamate, continue to stir for 40min; finally add 0.1g of TBHQ and 0.2g of polymethacrylate pour point depressant (SANYO's ACLUBEP-2100), and stir for another 30min to obtain the product .

[0025] The appearance of the obtained product is a tan transparent viscous liquid, and the maximum non-jamming load PB value can reach 180kg.

Embodiment 2

[0027] First, weigh 55g of epoxidized soybean oil (the kinematic viscosity at 40°C is 34mm 2 / s). Add to the blending kettle, then add 10g of trimethylolpropane fatty acid ester, 10g of chlorinated paraffin S-52, 15g of sulfurized lard, 4g of sulfur-containing extreme pressure agent RC2540, 1g of oily phosphoric acid Esters, warmed up slightly to 55°C, stirred for 30min; then added a mixture of 1g of sodium petroleum sulfonate and 1g of benzotriazole, 0.8g of benzisothiazolinone and 0.2g of 3-iodo-2- The mixture of propynyl butyl carbamate, continue to stir for 40min; finally add 0.1g of TBHQ and 0.2g of polymethacrylate pour point depressant (SANYO's ACLUBEP-2100), and stir for another 30min to obtain the product .

[0028] The appearance of the obtained product is a tan transparent viscous liquid, and the maximum non-jamming load PB value can reach 170kg.

Embodiment 3

[0030] First, weigh 65g of epoxidized soybean oil (the kinematic viscosity at 40°C is 34mm 2 / s) into the blending kettle, then add 10g of chlorinated paraffin S-52, 15g of vulcanized lard, 4g of sulfur-containing extreme pressure agent RC2540, and 1g of oily phosphate, slightly warm up to 55°C, and stir for 30min; then Then add the mixture of 1g of sodium petroleum sulfonate and 1g of benzotriazole, the mixture of 0.8g of benzisothiazolinone and 0.2g of 3-iodo-2-propynyl butyl carbamate, Continue stirring for 40 minutes; finally add 0.1 g of TBHQ and 0.2 g of polymethacrylate pour point depressant (ACLUBEP-2100 from SANYO), and stir for another 30 minutes to obtain the product.

[0031] The appearance of the obtained product is a brown transparent viscous liquid, and the maximum non-jamming load PB value can reach 160kg.

Abstract

The invention discloses an environmentally-friendly cold heading oil with epoxidized vegetable oil as base oil, and a preparation method thereof. The environmentally-friendly cold heading oil is prepared through adding a lubricant, an antirust agent, an extreme pressure agent, an antiseptic, an antioxidant and pour-point depressant to the epoxidized vegetable oil used as the base oil. The epoxidized vegetable oil is used as the base oil to substitute traditional non-renewable mineral oil, so consumption of non-renewable resources is avoided, and pollution to environment is greatly reduced. The environmentally-friendly cold heading oil is suitable for various machining, such as carbon steel cold heading, molding processing hot headed nuts, high-strength bolt sleeves and hollow and semi-hollow rivets, and molding processing of rivets; and the preparation method is simple and has low requirements about devices.

Description

technical field [0001] The invention belongs to the field of cold forming processing of metal workpieces, and in particular relates to a novel cold heading oil and a preparation method thereof. Background technique [0002] With the development of metallurgy, automobiles, ships, aerospace and other technologies, more and more metal parts need to be formed and processed, and the required precision and load are also getting higher and higher. Pressure, cleaning, antirust and other performance requirements are getting higher and higher, and the requirements for environmental protection are becoming more and more stringent. Traditional cold heading oil is based on mineral oil. Although it has a little advantage in cost performance, it is a derivative of non-renewable resources and has poor biodegradability. After long-term discharge and accumulation, it will cause serious pollution to the ecological environment. When manufacturers adopt products, they should not only consider t...
