Beschreibung
Zusammenfassung:	The invention discloses a composition for preparing paste paper, application of the composition in paste paper preparation, a preparation method of the paste paper, and the paste paper prepared by using the preparation method. The composition comprises polyethylene, calcium carbonate and starch, and based on the total weight of the composition, the polyethylene accounts for 10-17 wt%, the calcium carbonate accounts for 72-78 wt%, and the starch accounts for 10-15 wt%; the MFR of the polyethylene under the action of load of 2.16 kg at the temperature less than 230 DEG C is 0.03-1 g/10min. The paste paper prepared by using the composition is relatively high in deflection and mechanical property, low in water-absorbing quality, and free from released chlorine, so that the application prospect is widened.
