Production manner null of the latex for paper coat

摘要

Topic Although this invention relating to the styrene - butadiene latex, especially, being included by the composition for paper coating and maintaining printing physical properties it is something regarding the production method of the latex for paper coating which can grant the adhesive strength which is superior.SolutionsThis invention because of this, i) single functionality thiol based chemical compound, and II) the chain transfer agent adding 0.1 which includes the multi functionality thiol based chemical compounds which possess the thiol basis of two or more or 10 weight sections vis-a-vis the styrene and the butadiene monomer composition 100 weight section, offers the production method of the styrene - butadiene latex which includes the stage which it makes emulsify makes polymerize.Because the latex which is produced with method of this invention the adjustment of the molecular weight and gel content being easy, improves the physical properties of polymerization stability and mechanical stability, including this, it makes high-speed printing of the paper which is produced possible, it is possible to improve adhesive strength.
