11зобретение относитс к способам The invention relates to methods.
получени водостойких св зукицих на основе технических лигносульфонатов и может быть использовано на предпри ти х целлюлозно-бумажной промьшшен- ности и при строительстве и эксплуатации гравийных дорог.production of water resistant bonds based on technical lignosulfonates and can be used in pulp and paper industry and in the construction and operation of gravel roads.
Цель изобретени - повышение водостойкости и прочнЪсти покрытий. The purpose of the invention is to increase the water resistance and durability of coatings.
Способ осуществл етс следующим образом.The method is carried out as follows.
Сульфитно-дрожжевую бражку, содержащую в основном лигносульфонаты натри , упаривают до концентрации сухих веществ 47%. Полученный концентрат охлаждают до 60-80°С и при посто нном перемешивании ввод т в него фосфогипс в виде 50%-ного раствора в количестве 5-5,7%, затем продукт нейтрализуют аммиачной водой до рН 5,5-6,0.Sulfite-yeast brew, containing mainly sodium lignosulfonates, is evaporated to a dry matter concentration of 47%. The resulting concentrate is cooled to 60-80 ° C and, with constant stirring, phosphogypsum is introduced into it in the form of a 50% aqueous solution in an amount of 5-5.7%, then the product is neutralized with ammonia water to a pH of 5.5-6.0.
В таблице приведены примеры осуществлени способа.The table shows examples of the implementation of the method.
Как видно, при введении фосфогипсаAs you can see, with the introduction of phosphogypsum
в количестве, меньшем чем 5%, увеличиваетс в зкость продукта, снижаетс его прочность и растворимость. При введении фосфо1:ипса в количестве,, большем чем 7,5%,-хот и не снижаетс предел йрочности образцов, но ухудшаетс их водостойкость.in quantities less than 5%, increases the viscosity of the product, decreases its strength and solubility. With the introduction of phospho1: ipsa in an amount of more than 7.5%, although the limit of the urgency of the samples does not decrease, but their water resistance deteriorates.
Пример выполнени известного способа . Сульфитно-дрожжевую бражку, содержащую в основном лигносульфонат натри j упаривают до концентрации сухих веществ 47%. Полученньй концентрат охлаждают до 60-80 С и при посто нном перемешивании ввод т в него 50%-ный раствор хлористого кальци в количестве 30%. После получени однородной массы смесь нейтрализуют аммиачной водой до рН 5,0- 5,2. В св зующем, полученном по описанному способу, определ ют товарные свойства: предел прочности высушенных образцов 0,87 МН/м, растворимость высушенных образцов 5,0 мг/мин.An example of a known method. A sulphite yeast brew containing mainly sodium lignosulfonate j is evaporated to a dry matter concentration of 47%. The resulting concentrate is cooled to 60-80 ° C and, with constant stirring, a 50% solution of calcium chloride in an amount of 30% is introduced into it. After a homogeneous mass is obtained, the mixture is neutralized with ammonia water to a pH of 5.0-5.2. In the binder obtained by the described method, commercial properties are determined: the tensile strength of the dried samples is 0.87 MN / m, the solubility of the dried samples is 5.0 mg / min.
