Problems solved by technology

[0007] However, in the field of papermaking, there are no relevant technical solutions and literature reports on adding metal powder to pulp. This is mainly due to the different properties of metal powder and graphite powder. Adding metal powder to pulp will lead to the final strength of the paper. Reduced, no longer able to meet the basic needs of making corrugated cardboard
In addition, although coating coatings on corrugated cardboard is a technical means often used by those skilled in the art, for example, the process of coating antistatic coatings on the surface of corrugated cardboards is mentioned in the patent document CN107022926B. However, the coating Insufficient adhesion to cardboard will cause the coating film to be easily scratched off and cannot perform its function well
It is difficult to find a coating on the market that has both antistatic and waterproof functions and has good adhesion to corrugated cardboard. However, the method of using double coatings will cause the corrugated cardboard to become thicker and cause the corrugated cardboard to lose its lightness. texture
In summary, it is difficult to obtain a corrugated packaging material with good waterproof performance and good antistatic function through some methods of the prior art

Abstract

The invention relates to the field of corrugated paper processing, in particular to a waterproof antistatic corrugated board, which is manufactured by the steps of burdening, paper pulp manufacturing,body paper manufacturing, paperboard manufacturing, paperboard forming and waterproof layer coating and brushing. The paper pulp comprises the following components: premixed water, basic cellulose powder, added water, functional cellulose powder, silver powder, sodium hydroxide, a bridging agent and a stabilizer. A waterproof layer coating is prepared from the following components: waterborne polyurethane emulsion, functional cellulose powder, water for adjusting viscosity and a coalescing agent. The functional cellulose powder is glycine grafted cellulose, and the grafting rate is 1.5-3%. The corrugated board prepared from the paper pulp has a good antistatic effect; the waterproof coating coated on the corrugated board can effectively realize a waterproof function; the paper pulp manufacturing method is simple and convenient, the obtained paper pulp is uniform and stable, and subsequent paper forming is facilitated.

Description

Technical field [0001] The invention relates to the field of corrugated paper processing, more specifically, it relates to a waterproof and antistatic corrugated paperboard. Background technique [0002] Corrugated cardboard is a commonly used packaging material that can be used to make packaging boxes. [0003] When packaging electronic products, there are often antistatic requirements for packaging materials. Therefore, there are many patent documents in the prior art that record related improvements to corrugated paper or corrugated paper packaging boxes. [0004] For example, the Chinese Invention Patent with the Patent Authorization Announcement Number CN102154900B discloses a method for preparing antistatic carbon fiber corrugated paper. The pulp is added with graphite with good conductivity, and the process steps to make the graphite better mixed in the pulp are designed accordingly. . For example, the Chinese Invention Patent with the Patent Authorization Announcement No. C...
