Embodiment 1
[0033] Add 1 part hectorite powder gradually to preheated to 60°C with constant stirring o C in 100 parts of deionized water, after uniform dispersion, cooled to room temperature, directly used as the water phase. Take 50 parts of ASA (octadecenyl succinic anhydride) as the oil phase. Add the water phase prepared above into the oil phase under stirring, and use high-speed emulsification and shearing equipment to stir and emulsify at a speed of 1000 rpm for 10 minutes to obtain an oil-in-water ASA emulsion. The mass percentage of ASA in the emulsion is About 33%, after the emulsion was left for 24 hours, the water phase precipitated out at the bottom.
[0034] Take 100 parts of beating degree is about 42 o SR poplar bleached thermomechanical pulp was added to 9900 parts of water, and after being decomposed by a fiber deflagging machine, 1 part of Al was added 2 (SO 4 ) 2 ?18H 2 O, mix and stir for 1 minute, add 1 part of the ASA emulsion sizing agent prepared above, stir ...
Embodiment 2
[0037] Add 1 part hectorite powder gradually to preheated to 60°C with constant stirring o 50 parts of deionized water of C, after uniform dispersion, cooled to room temperature; 0.1 part of melamine was dissolved in 50 parts of deionized water under stirring, and mixed with the above laponite dispersion as the water phase; 50 parts of ASA ( octadecenyl succinic anhydride) as the oil phase. Add the water phase prepared above into the oil phase under stirring, and use high-speed emulsification and shearing equipment to stir and emulsify at a speed of 1000 rpm for 10 minutes to obtain a stable and uniform oil-in-water ASA emulsion. The mass percentage of ASA was about 33%, and the appearance of the emulsion did not change after standing for 24 hours.
[0038] Take 100 parts of beating degree is about 42 o SR poplar bleached thermomechanical pulp was added to 9900 parts of water, and after being decomposed by a fiber deflagging machine, 1 part of Al was added 2 (SO 4 ) 2 ?18...
Embodiment 3
[0041] Gradually add 0.5 parts of hectorite powder to the preheated to 40 o 40 parts of deionized water of C, after uniform dispersion, cooled to room temperature; 0.005 parts of melamine was dissolved in 10 parts of deionized water under stirring, and mixed with the above laponite dispersion as the water phase; another 50 parts of ASA (hexadecenyl succinic anhydride) as the oil phase. Add the above-prepared water phase into the oil phase under stirring, and use high-speed emulsification and shearing equipment to stir and emulsify at a speed of 7500 rpm for 3 minutes to obtain a stable and uniform oil-in-water ASA emulsion. The mass percentage of ASA is about 50%, and the appearance of the emulsion does not change after standing for 24 hours.
[0042] Take 100 parts of beating degree is about 40 o SR poplar alkaline hydrogen peroxide mechanical pulp was added to 9900 parts of water, and after being decomposed by a fiber disintegrating machine, 1 part of Al 2 (SO 4 ) 2 ?18...
