Abstract
The present invention relates to a method for concentrating organic silicate polymer solution, and more precisely, a method for concentrating organic silicate polymer solution by distillation which is characterized by remarkably reduced distillation time realized by the short-term continuous distillation at low temperature under low pressure, minimized physical property changes attributed to the inhibition of the heat-induced reaction by making the solution pass through the thin film evaporator shortly, concentration without cake generation, and easy manipulation with high capacity, making the method highly economical.
Claims5
A method for concentrating organic silicate polymer solution, said method characterized by the distillation of an organic silicate polymer solution comprising an organic silicate in the range of 2 to 30 wt % and an organic solvent in the range of 70 to 98 wt % using an agitated thin film evaporator under low pressure with a jacket temperature in the range of 29 to 36° C.
