Problems solved by technology

[0003] However, the existing cartons made of corrugated cardboard have relatively poor deformation resistance, and most of them do not have waterproof effect, which makes the carton easily deformed by moisture and reduces the protective effect. Therefore, we propose a corrugated cardboard production process to solve the above problems

Abstract

The invention discloses a production process of a corrugated board. The production process comprises the following steps of Step 1, material preparation: preparing corrugated paper base paper, epoxy resin, polyvinyl chloride resin, dioctyl phthalate, white carbon black, triethylene glycol amine, phosphoric acid and a waterproof agent; Step 2, melting of main raw materials of an adhesive: sequentially weighing raw materials according to a raw material ratio of the adhesive; preparing a glue storage container; and putting the epoxy resin and the polyvinyl chloride resin into the glue storage container for primary melting to obtain a melt; and Step 3, adhesive preparation, and the like. The designed and prepared corrugated board is prepared by bonding multiple layers of corrugated paper basepaper through the adhesive, performing pressurization and lamination to form corrugated paper interlayer paper, and then bonding and laminating a layer of wave-shaped corrugated paper and two layers of corrugated paper interlayer paper. The prepared corrugated board has good strength and certain waterproof and moisture-proof properties; the proper laminating thickness can be freely selected according to use requirements; and the application scene of the corrugated paper is increased.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production and processing, in particular to a corrugated cardboard production process. Background technique [0002] With the rapid development of the economy, the application of packaging materials is becoming more and more popular, especially with the rapid development of the express delivery industry, the processing and production of packaging materials is in short supply. Corrugated cardboard is widely used, easy to make, and can be recycled or even reused, which has significantly increased its application. 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. After ...
