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.

Abstract

The invention discloses a preparation method of a special emulsifier for rosin emulsion, which belongs to the technical field of rosin deep processing. The present invention adopts the following raw materials in parts by weight: 5 to 8 parts of cardanol, 1 to 2 parts of polyethyl ether modified trisiloxane, 6 to 10 parts of ethanol, 0.1 to 0.2 parts of sulfonated lignin, 0.1 to 0.2 parts of dodecane 15-25 parts of sodium base sulfate and 10-15 parts of deionized water with a conductivity less than 5 μS / cm; including putting the above-mentioned deionized water into the reactor first, then adjusting its pH value to 9, and then adding Cardanol, polyethyl ether modified trisiloxane, ethanol, sulfonated lignin, sodium lauryl sulfate, and then heated to 80°C-95°C for 0.5 hours, then cooled to 55°C-65°C for 1 hour, then Then the temperature was raised to 80°C-95°C for 0.5 hour reaction. The invention is used for preparing the rosin emulsion, and has the advantages of high emulsifying activity and strong stability.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a preparation method of a special emulsifier for rosin emulsion. Background technique [0002] Rosin refers to a non-volatile natural resin obtained through different processing methods using pine resin as raw material. It is an important chemical raw material and is widely used in soap, paper, paint, rubber and other industries. In addition, rosin can also be modified or emulsified to make an emulsion, so that a certain aspect of rosin performance can be significantly improved, thereby expanding the application value of rosin. [0003] Among them, rosin can be used in the paper industry after being emulsified to make emulsion, and it can be filled between fibers to achieve the purpose of "gluing" or "sizing", thereby increasing the water resistance of paper, preventing ink penetration, improving strength and smoothness degree, reducing the degree of ex...
