Description
В производстве эмульсионных сннтетических бутадиенстирольных каучуков в качестве эмульгатора нримен етс некаль. Весьма желательна замена некал на канифольные мыла. Однако в прин тых промышленностью рецептах реакци полимеризации при использовании дл изготовлени мыла товарной канифоли идет крайне медленно.In the production of emulsion snfty styrene rubbers, non-scale is used as an emulsifier. It is highly desirable to replace nekal for rosin soaps. However, in commercially accepted recipes, the polymerization reaction is extremely slow when used to make commercial rosin soap.
Дл обеспечени нормального ведени процесса полимеризации предлагаетс товарную живичную канифоль подвергать предварительному нагреванию до 200-250°. Выдержанна при этой температуре в течение не менее 10 мин. живична канифоль модифицируетс и использование ее в виде мыла в р де рецептов эмульсионной полимеризации значительно ускор ет процесс, а также повышает воспроизводимость эмульсионной полимеризации.To ensure the normal conduct of the polymerization process, commercial gum rosin is proposed to be preheated to 200-250 °. Sustained at this temperature for at least 10 min. Gum rosin is modified and its use in the form of soap in a series of emulsion polymerization recipes significantly speeds up the process and also increases the reproducibility of emulsion polymerization.
Прогрев канифоли может осушествл тьс в открытом или закрытом стальном аппарате в атмосфере воздуха или инертного газа. Така обработка канифоли вл етс простой по аппаратурному оформлению, не требует катализатора и может быть легко осуществлена на канифольных заводах или на заводах синтетического каучука.Heating of rosin can be carried out in an open or closed steel apparatus in an atmosphere of air or inert gas. This treatment of rosin is simple in hardware, does not require a catalyst, and can be easily carried out in rosin factories or synthetic rubber plants.
Предмет изобретени Subject invention
Способ полимеризации синтетических ка т1уков в эмульси х, стабилизованных канифольными мылами, отличаюшийс тем, что, с целью ускорени процесса полимеризации,.примен ют товарную живичную канифоль, которую предварительно подвергают нагреванию до ; 200-250° и выдерживают при этой температуре не менее 10 мин.The method of polymerization of synthetic materials in emulsions stabilized with rosin soaps, characterized in that, in order to accelerate the polymerization process, commercial gum rosin is used, which is preliminarily heated to; 200-250 ° C and maintained at this temperature for at least 10 minutes.
