Abstract
The invention provides a fireproof flame-retardant corrugated paperboard, and a preparation method thereof. According to the preparation method, in a flame-retardant adhesive glue, aerosol, an enhancing resin, and a terpene resin are taken as the main raw materials, and accessory materials such as melamine, polyimide, and formaldehyde are added; in preparation, the ingredients are prepared into materials 1, 2, 3, 4, and 5 respectively; the obtained material 5 is subjected to baking so as to obtain the flame-retardant adhesive glue; and the flame-retardant adhesive glue is used for bonding corrugated paper, so that the excellent flame resistance and tear strength of the obtained fireproof flame-retardant corrugated paperboard can be ensured, the fireproof flame-retardant corrugated paperboard is suitable to be used for preparing corrugated cases used for packing products which are highly dangerous and extremly incendive, the safety of packaged products can be ensured in transportation process, and the preparation process is friendly to the environment.
Description
technical field [0001] The invention relates to the field of corrugated cardboard, in particular to a fireproof and flame-retardant corrugated cardboard and a preparation process thereof. Background technique [0002] Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. At present, the corrugated paper on the market cannot be effectively flame-retardant and fire-resistant. If it is too large, corrugated paper may burn, which greatly increases the safety of corrugated paper and is not conducive to the use of corrugated paper by users. Contents of the invention [0003] In order to overcome the above problems, the present invention provides a fireproof and flame retardant corrugated cardboard and its preparation process. [0004] To achieve the above object, the technical solution provided by the invention is: [0005] A fire-proof and flame-retardant corr...
