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.
