| Abstract:In this paper, the GWT transparent agent was prepared with complex formulation and the properties and applications of the transparent agent were studied in detail. The GWT transparent agent was a pale yellow emulsion with solids content 30% wt, refractive index 1.51 and viscosity 18.8mPa·s at 25℃. The GWT transparent agent could keep a stable property without layering and feculent in a long time under room temperature. The transparency of the paper treated with GWT transparent agent increased by 32.95% compared to the base paper, namely from 38.66% to 71.61%. At the same time, the mechanical strengthes of the paper were decreased. The transparent agent can be permeated into the paper rapidly under room temperature, the optimal permeating time was 5 seconds. The scanning electron microscopy analysis showed that, the transparent agent had a good retention rate in base paper with its adhesive ability to the fiber surface, and also the transparent agent could fill in the interspace beteeen the fibers. |
