High-water-absorption corrugated base paper and preparation method thereof

Abstract

The invention discloses high-water-absorption corrugated base paper and a preparation method thereof, wherein the high-water-absorption corrugated base paper is prepared from the following componentsby weight: 7-21 parts of bast fiber, 8-15 parts of glass fiber, 100-155 parts of wood pulp, 0.5-4 parts of a polyester binder, 3-7 parts of a dispersing agent, 3-7 parts of polyethylene, 9-15 parts ofstarch, 150-185 parts of clear water, 3-11 parts of polyester modified dimethyl polysiloxane, 1-3 parts of calcium carbonate, 0.3-2 parts of rosin, and 1-7 parts of sodium peroxide. According to thepresent invention, by adding rosin and bast fiber during the preparation of the high-water-absorption corrugated base paper, the strength and the toughness of the base paper are improved; the starch and the polyester modified dimethyl polysiloxane added to the external sizing can well improve the surface water resistance and the oil resistance of the paper; and through the overpressure treatment,the paper strength is good while the energy consumption is reduced.

Description

technical field [0001] The invention relates to a high water-absorbing corrugated base paper and a preparation method thereof. Background technique [0002] With the progress of society, the rapid development of express delivery industry. The demand for cartons used for the outer packaging of articles is also rising rapidly. Corrugated base paper is the key material for carton production, and the demand is also rising, and the quality of base paper has a decisive impact on the quality of finished cartons. Corrugated cardboard has good mechanical strength, can withstand a certain pressure from the plane, and is elastic and has a good cushioning effect. It can be made into liners or containers of various shapes and sizes according to needs, which is simpler and more convenient than plastic cushioning materials. Fast, less affected by temperature, good shading performance, and will not deteriorate under light, but corrugated paper packaging will easily permeate when exposed to...
