Zusammenfassung: | The invention discloses a carboxylic butadiene-styrene latex special for white paperboards. The carboxylic butadiene-styrene latex special for white paperboards is prepared from, by weight, 100-140 parts of deionized water, 7-8 parts of lauryl sodium sulfate, 4.5-6 parts of caustic soda, 1-4 parts of bentonite, 0.8-1.6 parts of disodium EDTA, 0.5-0.7 part of potassium chloride, 10-12 parts of an emulsifying agent, 20-25 parts of ammonium persulfate, 20-30 parts of sodium dodecyl benzene sulfonate, 20-30 parts of sodium hydroxide, 2-5 parts of a defoaming agent, 55-56 parts of acrylic acid, 200-500 parts of vinyl benzene, 300-600 parts of butadiene and 0.1-0.5 part of an initiator. According to the carboxylic butadiene-styrene latex special for white paperboards, bentonite linkage is integrally adopted to improve the bonding strength between butadiene-styrene latex, and the binding performance of the latex is improved; meanwhile, with the cooperation of the defoaming agent in the raw materials, foaming of the |
