Description
: Известные способы придани водоотталкивающих свойств волокнистому материалу, налример , различного вида :ка;рто-ну и бумаге, древесно-волокнистым плитам и- т. д., путем обработки их состава ми из водной двуокиси кремни и силикона, сложны в технологии и не обеспечивают высокого качества обработанного материала.: Known methods for imparting water-repellent properties to fibrous material, nalimer, of various types: ka; rto-nyu and paper, fibreboard, etc. provide high quality processed material.
По предлагаемому способу обработку материала указанными составами производ т одновременно , при этом добавл ют отверждающий катализатор.According to the proposed method, the processing of the material with the indicated compositions is carried out simultaneously, at the same time a curing catalyst is added.
Это дает возможность упростить технологию и повысить качество обрабатываемого материала.This makes it possible to simplify the technology and improve the quality of the processed material.
В качестве силикона быть применен полиалкилводородсилоксан, а в качестве отверждаюодего катализатора - раствор дибутилдилаурината олова в тетраэтоксисилане.Polyalkylhydrogen siloxane should be used as a silicone, and a solution of dibutyldyl uurinate tin in tetraethoxysilane will be used as a curing catalyst.
Водную двуокись кремни приготовл ют путем перемешивани на скоростной мешалке продукта «Аэросил-175 с водой до получени устойчивой водной дисперсии концентрации 10%.Silica water is prepared by mixing the product "Aerosil-175" with water on a high-speed stirrer with water until a stable aqueous dispersion has a concentration of 10%.
В качестве водоотталкиваюш;его силикона примен ют полиэтилводородсилоксан (ГКЖ94 ), в виде эмульсии. Эмульгатором служит поливиниловый спирт.As a water repellent, its silicone is polyethylenesiloxane (GKZh94), in the form of an emulsion. Emulsifier is polyvinyl alcohol.
К эмульсии полиэтилводородсилоксана добавл ют водную дисперсию двуокиси кремни . Волокнистый материал покрывают указанной смесью, затем высушивают и при необходимости разглаживают на сушильном цилиндре .An aqueous dispersion of silica is added to the emulsion of polyethylsiloxane. The fibrous material is coated with the mixture, then dried and, if necessary, smoothed on a drying cylinder.
