Embodiment 1
[0018] The preparation method of this rosin emulsion special emulsifier comprises the following steps:
[0019] Put 15kg of deionized water with a conductivity of less than 5μS / cm into the reactor, then adjust its pH to 9, then add 5kg of cardanol, 2kg of polyethyl ether modified trisiloxane, 8kg of ethanol, and 0.15kg of sulfonated lignin , 20kg of sodium lauryl sulfate, and heated for reaction to obtain; wherein, the specific process of heating is: first heating to 90°C for 0.5 hours, then cooling to 60°C for 1 hour, and then heating to 90°C React for 0.5 hours.
[0020] When the emulsifier prepared in this example is used to prepare rosin emulsion, its dosage is only 1% of the mass of rosin, and the obtained rosin emulsion has good stability and can be stored for 2 years at 40°C.
Embodiment 2
[0022] The preparation method of this rosin emulsion special emulsifier comprises the following steps:
[0023] Put 12kg of deionized water with a conductivity of less than 5μS / cm into the reactor, then adjust its pH value to 9, then add 8kg of cardanol, 1kg of polyethyl ether modified trisiloxane, 10kg of ethanol, and 0.1kg of sulfonated lignin , 15kg of sodium lauryl sulfate, and heated for reaction to obtain; wherein, the specific process of heating is: first heated to 95°C for 0.5 hours, then cooled to 55°C for 1 hour, and then heated to 95°C React for 0.5 hours.
[0024] When the emulsifier prepared in this example is used to prepare rosin emulsion, its dosage is only 2% of the mass of rosin, and the obtained rosin emulsion has good stability and can be stored for 2 years at 40°C.
Embodiment 3
[0026] The preparation method of this rosin emulsion special emulsifier comprises the following steps:
[0027] Put 10kg of deionized water with a conductivity of less than 5μS / cm into the reactor, then adjust its pH value to 9, then add 6kg of cardanol, 1.5kg of polyethyl ether modified trisiloxane, 6kg of ethanol, and 0.2kg of sulfonated wood element, 25kg sodium lauryl sulfate, and heated for reaction to obtain; wherein, the specific process of heating is as follows: first heating to 80°C for 0.5 hours, then cooling to 65°C for 1 hour, and then raising the temperature to 80°C °C for 0.5 hours.
[0028] When the emulsifier prepared in this example is used to prepare rosin emulsion, its dosage is only 1% of the mass of rosin, and the obtained rosin emulsion has good stability and can be stored for 2 years at 40°C.
