Problems solved by technology

[0006] 1. Corrugated cardboard has poor mechanical properties such as strength and is easy to be damaged or torn, which cannot meet the requirements of high-performance packaging corrugated boxes;
[0007] 2. The environmentally friendly adhesive used to bond the materials of each layer of corrugated cardboard either has low adhesion and low bond strength, which cannot meet the production requirements of environmentally friendly high-strength corrugated cardboard; or the adhesive has a high formaldehyde emission and is not easy to degrade ,Not environmentally friendly

Abstract

The invention discloses an environment-friendly high-strength corrugated cardboard and a manufacturing process thereof. The environment-friendly high-strength corrugated cardboard sequentially comprises: a first waterproof outer layer (1), a first cardboard layer (3), a first nylon-free Woven fabric layer (4), corrugated core paper layer (5), second nylon non-woven fabric layer (6), second cardboard layer (7) and second waterproof outer layer (9), with environmental protection Adhesive bonding; the first waterproof outer layer (1) and the second waterproof outer layer (9) are both waterproof coated paper. The environment-friendly high-strength corrugated cardboard of the present invention has the advantages of high edge crush strength, high bursting strength and high puncture strength, good mechanical properties, not easy to be damaged or torn, and can meet the requirements of high-performance packaging corrugated boxes, and is suitable for The packaging of some fragile items with high quality and high value; the bonding between the layers is firm, and the adhesive has good anti-aging and waterproof effects; it is not easy to absorb moisture and can well maintain its mechanical properties.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard and its production, in particular to an environment-friendly high-strength corrugated cardboard and its production process. Background technique [0002] Corrugated box is an ideal packaging container, which is light, strong, vibration-absorbing and suitable for mechanized production. It has been used for transportation packaging and sales packaging for many years. Corrugated boxes have won the market for their exquisite appearance and inner good quality. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Especially when all countries in the world attach great importance to environmental protection, corrugated boxes have the advantages of recycling, which is beneficial to environmental protection, loading and unloading and transportation, and saving wood. [0003] Corrugated cardboard is the...
