Problems solved by technology

[0004] However, the existing corrugated cardboard also has some shortcomings as packaging materials: on the one hand, corrugated paper has poor moisture resistance, and it is easy to cause the strength of corrugated paper to decrease due to water infiltration, or even collapse and damage. When the stack is heavy, it is difficult to bear its weight, easy to deform or cause collapse damage

Abstract

The invention discloses a three-layer composite waterproof corrugated board and a preparation technology thereof. The preparation technology of the three-layer composite waterproof corrugated board comprises the following steps: 1, preparing corrugated paper layers; 2, treating surface paper and inner paper: immersing the surface paper and inner paper in a reinforcing solution, taking out the surface paper and the inner paper after the surface paper and the inner paper are completely soaked, and drying the surface paper and the inner paper in a 45-55 DEG C environment, wherein the reinforcingsolution is prepared through mixing, by weight, 0.7-1.1 parts of modified bentonite, 0.5-0.9 part of nano-silica, 1.2-1.6 parts of ceramic powder, 5-10 parts of an acrylate emulsion and 1.3-1.6 partsof silica sol; 3, performing gluing and compounding; and 4, coating with a waterproof coating. The three-layer composite waterproof corrugated board of the invention has the advantages of high strength, good bending resistance, and good waterproof and moisture-proof performances; and the preparation technology of the invention has a simple preparation process.

Description

technical field [0001] The invention relates to the technical field of corrugated paper, more specifically, it relates to a three-layer composite waterproof corrugated board and its preparation process. Background technique [0002] As the most important packaging material, corrugated paper has the advantages of light weight and low cost compared to other packaging materials (such as wood, cardboard, etc.). The weight of three-layer corrugated cardboard is about 600g / m 2 , while the weight of a board of the same thickness is about 2000g / m 2 , It is more than 3 times that of corrugated cardboard. [0003] Corrugated paper is a composite material composed of cellulose fibers and polymer binders. Its raw material is base paper, which can be made from wood pulp (wood leftovers) and straw pulp, and can be reused conveniently. Due to the flatness of the cardboard, it can be printed conveniently, and can be folded, occupying a small space during storage and transportation. [00...
