Rushan Beihua to share with you to oxidize polyethylene wax as the main raw material for the preparation of paper coating special lubricant production process
The process for producing a special lubricant for papermaking coating with oxidized polyethylene wax as a main raw material is characterized by comprising the steps of:
(1) 0.1 part of morpholine was added as a raw material of 1 part of oxidized polyethylene wax, and the mixture was stirred at about 2,500 rpm for 2 hours in a glass-lined reactor and subjected to nitrogen protection during the reaction at 115 to 120C Dropping to 80 ° C, adding 20% of the amount of polyethylene oxide wax of deionized water, stirring at the same speed for 2 hours to produce water-in-oil emulsion into A component;
(3) alkylphenol polyoxyethylene ether-10 (OP-10) or octylphenol polyoxyethylene ether-10 (TX-10) or nonylphenol polyoxyethylene ether-10 (NP-10 ) Surfactant and 0.2 part of sodium trimetaphosphate were used in a baking glass reactor and the mixture was stirred at 80 to 85 ° C for 5 hours to convert the surfactant to an anionic type and adjusted to a pH of 8 to 9, B component;
(3) 0.2 part of sorbitan monooleate (pan-80) emulsifier was added to 1 part of creek as a raw material and stirred in a glass-lined reactor at a temperature of 180 to 185 ° C at about 1200 rpm 2 hours, and then cooled to 80 ° C, adding 50% of the amount of deionized water, the formation of water mixture mixture from the C component;
(4) The A component, the B component, the C component and the deionized water were mixed with a 2: 1.5: 0.5: 6 ratio and the mixture was emulsified at 120 to 125 ° C for 2 hours with a homogeneous emulsifier , In 10 minutes to -10 ~ 0 ℃ frozen saline as coolant in the mixing kettle jacket cycle, cooling to 30 ~ 35 ℃ to continue emulsification for 30 minutes, to obtain its solid content of 25% oil-in-water emulsion products.
