Embodiment 1

[0016] The preparation method of this rosin emulsion special emulsifier is as follows:

[0017] In a stirring state, mix 5kg of cardanol, 2kg of polyethyl ether modified trisiloxane, 8kg of ethanol, 0.15kg of sulfonated lignin, 20kg of sodium lauryl sulfate and 15kg of deionized water with a conductivity of less than 5μS / cm , and then heated to 80 ° C, constant temperature reaction for 2 hours.

[0018] 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

[0020] The special emulsifier for this rosin emulsion comprises the following preparation steps:

[0021] In a stirring state, mix 8 kg of cardanol, 1 kg of polyethyl ether modified trisiloxane, 10 kg of ethanol, 0.1 kg of sulfonated lignin, 15 kg of sodium lauryl sulfate, and 12 kg of deionized water with a conductivity of less than 5 μS / cm , and then heated to 65 ° C, constant temperature reaction for 2 hours.

[0022] 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

[0024] The special emulsifier for this rosin emulsion comprises the following preparation steps:

[0025] In a stirring state, mix 6kg of cardanol, 1.5kg of polyethyl ether modified trisiloxane, 6kg of ethanol, 0.2kg of sulfonated lignin, 25kg of sodium lauryl sulfate and 10kg of deionized water with a conductivity of less than 5μS / cm uniform, then heated to 60°C, and reacted at constant temperature for 1 hour.

[0026] 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 special emulsifier for rosin emulsion and belongs to the technical field of rosin deep processing. The emulsifier is prepared from, by weight, 5-8 parts of cardanol, 1-2 parts of polyethylether modified trisiloxane, 6-10 parts of ethyl alcohol, 0.1-0.2 part of lignin sulfonate, 15-25 parts of sodium lauryl sulfate and 10-15 parts of deionized water with the electric conductivity smaller than 5 microseconds per centimeter. The emulsifier is prepared with cardanol, polyethylether modified trisiloxane, ethyl alcohol, lignin sulfonate, sodium lauryl sulfate and deionized water with the electric conductivity smaller than 5 microseconds per centimeter as the raw materials. The emulsifier is used for preparing the rosin emulsion and has the advantages of being high in activity and high in stability.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to 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 expansion. [0004] Rosin...
