A kind of fireproof flame retardant corrugated paper

Abstract

The application provides a fire-resistant and flame-retardant corrugated paper, which includes an upper cardboard, a corrugated paper core and a lower cardboard, and the upper cardboard and the lower cardboard are respectively bonded to the corrugated paper core by an adhesive. The upper and lower surfaces of the upper cardboard and the lower cardboard are provided with a flame-retardant layer, and the flame-retardant layer is composed of the following raw materials in parts by weight: 20-55 parts of titanate coupling agent modified montmorillonite, 10-30 parts of cerium oxide, 10-35 parts of nano-silica, 5-30 parts of phosphazene compounds, 5-15 parts of phosphate ester, 10-30 parts of polyurethane. The binder is composed of the following raw materials in parts by weight: 10-20 parts of graphene oxide, 15-25 parts of aluminum hydroxide, 5-20 parts of diatomaceous earth, 25-40 parts of ammonium polyphosphate, 12-28 parts of melamine, dispersed 30-55 parts of emulsifier, 1-5 parts of emulsifier, 15-40 parts of terpene phenolic resin. The flame-retardant substances on the outer surface of corrugated paper and in the adhesive can effectively improve the fire-proof and flame-retardant performance of corrugated paper, protect the packaged goods, and also reduce the spread of environmental fire. In addition, the flame retardant material inside the corrugated paper is not easy to drop, which can improve the durability of fire and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of corrugated paper, in particular to a fireproof and flame-retardant corrugated paper. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It has good elasticity and elongation, and is widely used in the manufacture of cartons, carton sandwiches, and fragile goods. Packaging materials to facilitate the transportation and storage of products. [0003] Corrugated cardboard is mainly made of base paper fibers, which are easily affected by external environmental factors such as temperature and humidity. In a high temperature environment, corrugated cardboard fibers are easy to absorb heat and conduct the absorbed heat to the items in the box. Thereby reducing the quality of some items, and even causing damage to the items, resulting in a waste of resources. In an environment such as open flames, due to the flamma...
