Examples
Embodiment 1
[0032] Embodiment 1: the preparation of cationic dispersed rosin gum (I)
[0033] Step 1: Preparation of 50% rosin ethanol solution:
[0034] Add 50 parts of rosin and 50 parts of ethanol into a 250ml Erlenmeyer flask, place the Erlenmeyer flask in a water bath, stir at a speed of 200-300rpm / min, raise the temperature of the water bath to 50°C, and continue stirring until the rosin dissolves When finished, take out the Erlenmeyer flask, cool to room temperature, plug it, and keep it for later use.
[0035] Step 2: Preparation of cationized maleic rosin A:
[0036] Add 5 parts of maleic rosin, 15 parts of ethanol and 0.8-1 part of NaOH into a four-necked bottle with a stirrer and a reflux condenser in sequence, start the stirrer, heat up to 50-60°C, and wait for the maleic rosin and After the NaOH solid is dissolved, add 6 parts of epichlorohydrin and 5 parts of trimethylamine, heat up to 75-90°C, reflux for 20-30 hours, stop the reaction, transfer the reaction system to a rota...
Embodiment 2
[0043] Embodiment 2: the preparation of cationic dispersed rosin gum (II)
[0044] Step 1: Preparation of 50% rosin ethanol solution:
[0045] Add 40 parts of rosin and 60 parts of ethanol into a 250ml Erlenmeyer flask, place the Erlenmeyer flask in a water bath, stir at a speed of 200-300rpm / min, raise the temperature of the water bath to 50°C, and continue stirring until the rosin dissolves When finished, take out the Erlenmeyer flask, cool to room temperature, plug it, and keep it for later use.
[0046] Step 2: Preparation of cationized maleic rosin A (same as Example 1).
[0047] Step 3: Preparation of cationic complex emulsifier B:

[0049] Step 4: the preparation of cationic rosin gum (II):
[0050] In a 250 ml beaker, mix 3 parts of 50% rosin et...
Embodiment 3
[0053] Embodiment 3: the preparation of cationic dispersed rosin gum (III)
[0054] Step 1: Preparation of 50% maleic rosin ethanol solution:
[0055] Add 50 parts of maleic rosin and 50 parts of ethanol in a 250 ml conical flask, place the conical flask in a water bath, stir at a speed of 200 to 300 rpm / min, raise the temperature of the water bath to 50°C, and continue stirring until Until the rosin is completely dissolved, take out the Erlenmeyer flask, cool to room temperature, plug it, and keep it for later use.
[0056] Step 2: Preparation of cationized maleic rosin A (same as Example 1).
[0057] Step 3: Preparation of cationic complex emulsifier C:
[0058] In a 250ml beaker, mix 1 part of emulsifier OP-10, 1 part of AEO-9, 1 part of dodecyltrimethylammonium chloride and 1.2 parts of cationized maleic rosin A, stir evenly with a glass rod Cationic complex emulsifier C can be obtained.
[0059] Step 4: the preparation of cationic rosin gum (III):
[0060] In a 250 m...
