Abstract

The invention belongs to the technical field of special paper, and particularly relates to high-toughness non-woven coated paper and a preparation method thereof. The high-toughness non-woven coated paper comprises, in weight percent, 50-60% of bleached sulfate hardwood pulp, 30-40% of sulfate softwood pulp, 5-15% of polyester fibers, 2-5% of adhesives and 3-5% of auxiliaries, wherein the auxiliaries are mixture of dry strength agents, wet strength agents, dispersing agents, defoaming agents, ultraviolet absorbents and antioxidants. The high-toughness non-woven coated paper is soft, good in folding endurance, uniform in color, stable and compatible and natural in hand feeling, the materials are more environmentally friendly than PVC (polyvinyl chloride), and the use range of decorative paper is widened. The preparation method is simple in process operation and easy to control, product quality is stable, a large number of manpower and material resources are saved, the production processof products is optimized, product quality is improved, the production requirements of users can be more effectively met, and production technology and technical level reach international advanced level.

Description

technical field [0001] The invention belongs to the technical field of special paper, and particularly relates to a high tenacity non-woven wrapping paper and a preparation method thereof. Background technique [0002] At present, the use of paper materials to replace PVC has become the norm for the continuously developing decoration industry. After the replacement, the damage to the environment can be reduced in the later processing. In the long run, decorative paper will also be selected in terms of environmental protection. [0003] At the same time, the decoration industry is indispensable to use irregular decoration styles such as arcs and curved edges. The use of decorative paper can improve the scope of decoration, and can achieve the decoration effect of bright and stable colors and rich patterns. This will affect the selection of decoration materials, and the demand for the market will also increase, which will bring good economic benefits for enterprises to produce...
