Production method of waterproof wear-resistant homogeneous dual-layer corrugated enhanced paperboard

Abstract

The invention discloses a production method of a waterproof wear-resistant homogeneous dual-layer corrugated enhanced paperboard. Silanization modification is conducted in emulsified asphalt modifiedby neoprene latex, the elasticity and wear resistance of silica sol and the water resistance of the emulsified asphalt are effectively combined, and waterproof wear-resistant glue excellent in waterproof and wear-resistant performance is obtained; the glue is used for coating modification of the inner surface and the outer surface of a corrugated paperboard, the glue is pressed into fiber pits andpores of the corrugated paperboard through a high-temperature and high-pressure processing technology, and the glue is combined with fiber to form a compact and firm waterproof wear-resistant layer;in the dynamic transporting process, the coating scratching phenomenon can be effectively reduced, and meanwhile waterproofing is effectively achieved. Two corrugated paper cores coated with the waterproof wear-resistant glue are combined through a corrugated paper core coinciding technology, homogeneous dual-layer real-time combining and corrugating are achieved, processing time can be saved andproduction cost can be reduced compared with an ordinary corrugated paperboard technology, and meanwhile the toughness, strength and waterproof performance of the corrugated paperboard are further enhanced.

Description

technical field [0001] The invention relates to the technical field of corrugated paper, in particular to a production method of waterproof and wear-resistant homogeneous double-layer corrugated reinforced cardboard. Background technique [0002] Corrugated cartons have a good protection function for the packaging. The specifications and sizes of the cartons are easy to change. They can adapt to various types of decoration and printing. They are convenient for sealing and bundling. The box can be recycled, energy saving and environmental protection. However, the strength of corrugated boxes is limited, and it is easy to be worn or even worn out by hard inner products during transportation, thus losing the function of protecting products; and the waterproof and moisture-proof effect of corrugated paper is limited, which limits its application in food transportation such as cold chain packaging. As well as the transportation of products in rainy weather, the poor waterproof e...

Problems solved by technology

However, the strength of corrugated boxes is limited, and it is easy to be worn or even worn out by hard inner products during transportation, thus losing the function of protecting products; and the waterproof and moisture-proof effect of corrugated paper is limited, which limits its application in food transportation such as cold chain packaging. And in the transportation of products in rainy weather, the poor waterproof effect may cause damage to the carton and cause the carton to lose its protective effect

At present, the method of building foam plastic in the carton is used to solve the problem that the carton is easy to be damaged. However, due to the use of foam material, it obviously does not meet the environmental protection requirements. This requires the production of a carton that can be wear-resistant and waterproof. Corrugated boxes with excellent performance to meet the needs of today's social development
