Powdered latex toughening agent with good dispersibility as well as preparation method and application thereof
The invention discloses a powdered latex toughening agent with good dispersibility as well as a preparation method and application thereof. The preparation method comprises the steps of weighing a first part of sodium p-styrenesulfonate, low-molecular polybutadiene, a first part of styrene, a second part of sodium p-styrenesulfonate, itaconic acid and a second part of styrene as the total amount of monomers; preparing a first part of sodium p-styrenesulfonate aqueous solution, adding a first part of surfactant, and uniformly mixing to obtain a seed emulsion; dissolving a second part of surfactant in water, adding into the mixture of the low-molecular polybutadiene and the first part of styrene, and uniformly emulsifying to obtain an emulsion; dissolving the second part of sodium p-styrenesulfonate in water, adding itaconic acid, and uniformly stirring to obtain a solution 1; heating the seed emulsion while stirring, adding the second part of styrene, heating, adding a first part of initiator aqueous solution, continuously heating, respectively dropwise adding the emulsion and the solution 1, dropwise adding a second part of initiator aqueous solution, and continuously reacting after dropwise adding to obtain liquid latex; and drying to obtain the powdered latex toughening agent with good dispersibility.
本发明公开了一种分散性良好的粉化胶乳增韧剂及制备方法与应用，制备为：称取第一份苯乙烯磺酸钠、低分子聚丁二烯、第一份苯乙烯、第二份苯乙烯磺酸钠、衣康酸和第二份苯乙烯为单体总量；制备第一份苯乙烯磺酸钠水溶液，加入第一份表面活性剂，混匀得种子乳液；将第二份表面活性剂加水溶解，加入到低分子聚丁二烯和第一份苯乙烯的混合物中，乳化均匀得到乳液；将第二份苯乙烯磺酸钠溶于水中，加入衣康酸，搅拌均匀，得溶液1；将种子乳液在搅拌下，加热，加入第二份苯乙烯，加热，加入第一份引发剂水溶液，继续加热，分别滴加乳液和溶液1，将第二份引发剂水溶液滴加，滴加完毕继续反应得液体胶乳；干燥，得到一种分散性良好的粉化胶乳增韧剂。
