Abstract
The invention discloses a manufacturing method of a special-shaped corrugated board hollow building block, and belongs to the technical field of special-shaped corrugated boards. The manufacturing method comprises the following steps: S1, sampling, specifically, screening out special-shaped corrugated boards with required sizes; S2, forming, specifically, putting the special-shaped corrugated boards in the step S1 into a corrugated paper forming machine for forming treatment, so as to prepare the special-shaped corrugated board hollow building block; and S3, coating, specifically, placing a waterproof flame-retardant coating in a coating machine, conducting roller type quantitative coating on one face or two faces of the corrugated boards, the total coating weight is not lower than 1.5 / m<2> in terms of dry film, wherein the waterproof flame-retardant coating is prepared from the following components in percentage by weight: 37% of organic silicon modified polyurethane aqueous dispersoid. The corrugated board hollow building block has better waterproof and flame-retardant properties, fire disasters caused by accumulation of corrugated cartons can be avoided, the safety of the corrugated cartons during use is improved, and meanwhile, the manufacturing method is reasonable in design, simple in process and energy-saving.
Description
technical field [0001] The invention relates to the technical field of special-shaped corrugated cardboard, in particular to a method for manufacturing a hollow block made of special-shaped corrugated cardboard. Background technique [0002] With the rise and explosive development of e-commerce, logistics and express delivery industries, the amount of corrugated cardboard used as packaging materials has also shown a substantial increase, and the corrugated cardboard industry has entered a period of rapid development and growth. Corrugated cardboard, also known as corrugated cardboard, is a multi-layer cardboard formed by processing corrugated base paper into a corrugated shape and bonding it with boxboard in a certain way. It is made of at least one layer of corrugated paper and a layer of boxboard. Good strength, elasticity and stiffness. [0003] Since the main component of corrugated cardboard is plant cellulose, it will be dehydrated and oxidized as the temperature rise...
