Problems solved by technology

[0002] In real life, cultural relics are usually protected by packaging paper capsules for cultural relics, but the processing methods of the existing capsules on the market are usually more complicated. The packaging paper capsules for cultural relics are usually made of acid-free cardboard, while the existing acid-free cardboard is usually The service life is short, and the strength of the cardboard is small, it is easy to deform and bend, and it is prone to creases and cracks. Moreover, the surface of the existing acid-free cardboard is prone to mildew, and it is also easy to cause mildew to the carried objects

Abstract

The invention discloses an acid-free paper board manufacturing method which includes the steps: A, producing a corrugated paper board on a paperboard machine by first acid-free paper; B, pasting second acid-free paper on the lower surface of the corrugated paper board; C, pasting third acid-free paper on the upper surface of the corrugated paper board; D, pasting acid-free dark grey coated paper on the upper surface of the third acid-free paper to prepare an acid-free paper board. The acid-free paper board prepared by the acid-free paper board manufacturing method has the advantages of comprehensive moisture protection, dust prevention, mold prevention, water vapor permeability prevention and oxidation resistance. Moreover, the acid-free paper board prepared by the manufacturing method ishigh in physical strength and has good breaking resistance, folding resistance and puncture resistance, the surface of the acid-free paper board is easily cleaned, the acid-free paper board is stablein color, and cultural relics can be more effectively protected.

Description
