High-strength carboxylic butadiene-styrene latex special for carpet and preparation method thereof

The invention discloses high-strength carboxylic butadiene-styrene latex special for carpet. The carboxylic butadiene-styrene latex is prepared from, by mass, 35-55 parts of butadiene, 45-65 parts of styrene, 0.8-1.5 parts of emulsifier, 1.1-1.8 parts of anti-aging agent, 1-2 parts of reinforcing agent, 40-85 parts of deionized water, 0.8-1.6 parts of filling agent, 1.3-2 parts of softening agent, 5-10 parts of tert-dodecylmercaptan, 20-30 parts of ammonium persulfate, 10-15 parts of caustic soda, 1-3 parts of initiator, 0.5-1.1 parts of anionic surface active agent, 1-2 parts of itaconic acid and 0.7-1.4 parts of fire retardant. The added reinforcing agent improves the strength of carboxylic butadiene-styrene latex, and the added softening agent improves the softness of carboxylic butadiene-styrene latex. 本发明公开了种地毯专用高强度羧基丁苯胶乳，所述羧基丁苯胶乳由以下质量份数的原料制成：丁二烯35-55份、苯乙烯45-65份、乳化剂0.8-1.5份、防老剂1.1-1.8份、补强剂1-2份、去离子水40-85份、填充剂0.8-1.6份、软化剂1.3-2份、叔十二碳硫醇5-10份、过硫酸铵20-30份、烧碱10-15份、引发剂1-3份、阴离子型表面活性剂0.5-1.1份、衣康酸1-2份和阻燃剂0.7-1.4份。本
