Waterproof corrugated paperboard

Abstract

The invention relates to the technical field of corrugated paperboards and provides a waterproof corrugated paperboard with good waterproof and dampproof effects, high strength and insusceptibility to deformation. The waterproof corrugated paperboard comprises a corrugated paperboard body, wherein the corrugated paperboard body is prepared from a plurality of layers of single-layer corrugated paperboards sprayed or dipped with a waterproof and dampproof agent by binding through an waterproof adhesive; the upper and lower surfaces of the corrugated paperboard body are provided with buffer layers; and the waterproof and dampproof agent is composed of the following raw materials by weight: 20 to 35 parts of dodecyl dimethyl benzyl ammonium chloride, 30 to 40 parts of octamethylcyclotetrasiloxane, 18 to 25 parts of sodium acrylate, 30 to 40 parts of N-isopropylacrylamide, 10 to 15 parts of butadiene, 10 to 15 parts phenyl diene, 5 to 10 parts of isproportionated potassium rosinate, 30 to 40 parts of trimethylol propane triacrylate, 20 to 30 parts of stearin, 3 to 10 parts of a pH regulator and 50 to 80 parts of water.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard, in particular to a waterproof corrugated cardboard. Background technique [0002] Corrugated cardboard began at the end of the 18th century and the beginning of the 19th century. Because of its light weight, cheap price, wide range of uses, easy production, and the ability to recycle or even reuse, its application has grown significantly. By the beginning of the 20th century, it had been fully popularized, promoted and applied for the production of packaging for various commodities. Since the packaging container made of corrugated cardboard has its unique performance and advantages for beautifying and protecting the goods inside, it has achieved great success in the competition with various packaging materials, and has become a long-lasting and presentable product so far. One of the main materials for the rapid development of packaging containers. Corrugated paper is a board-shaped...

AI Technical Summary

Problems solved by technology

Corrugated cardboard often encounters extrusion during use. When the corrugated cardboard is squeezed, the burst resistance of the corrugated cardboard has a great influence on the extrusion resistance of the cardboard. , there will be obvious deformation, which will affect the use of corrugated paper

The strength of three-layer cardboard in conventional products is low, and it is easy to deform during use. The strength of conventional five-layer cardboard is slightly higher than that of three-layer cardboard. However, due to insufficient manufacturing density, the strength is not high, and the consumption cost is high, occupying space and Big size

In addition, corrugated cardboard may be wetted by rainwater and sea water during use, which will affect its use. Conventional three-layer cardboard and five-layer cardboard are not waterproof and moisture-proof, and generally penetrate within 5 minutes. Sizing is the best It does not exceed 10 minutes and cannot protect the packaged items well
