Method for producing novel express box composite board by utilizing waste cartons

Abstract

The invention discloses a method for producing a novel express box composite board by utilizing waste cartons, which comprises the production steps of a, firstly, putting the waste cartons into a pulverizer to be pulverized to form carton scraps; b, after the step a is completed, coating super glue on an inner base plate of the composite board to form a strong coating, then uniformly laying the crushed scraps on the strong coating, then coating the super glue on the scrap layer to form a strong coating, and laying a layer of aluminum-foil paper on the strong coating to form a composite layer;and c, after the step b is completed, laying the outer base plate of the composite board outside the composite layer. According to the invention, the aluminum foil is laid in the composite board, protection and heat insulation are effectively achieved when the composite board is used, the phenomenon that objects in the composite board express box are wetted by water is prevented, the probability that the objects in the composite board express box are damaged is reduced, and the cargo protection effect of the express box made of the composite board is improved.

Description

technical field [0001] The invention relates to the technical field of composite boards for express boxes, in particular to a method for producing novel composite boards for express boxes by using discarded cartons. Background technique [0002] The main way to deal with waste cartons is that pulp mills use them as secondary raw materials to make pulp for reuse. However, the water pollution in this process is relatively serious, and the water consumption and drainage are relatively large (generally, more than 300 tons of water per ton of pulp and paper) , The content of organic matter in wastewater is high (PPT reflects: high biochemical oxygen demand (BOD) and high suspended solids (SS)), containing toxic substances that endanger the growth of aquatic organisms and affect industrial, agricultural, animal husbandry and residential water use. Accumulated for a long time, the suspended matter will silt up the river bed port and produce toxic odor of hydrogen sulfide, which wil...

[0002] The main way to deal with waste cartons is that pulp mills use them as secondary raw materials to make pulp for reuse. However, the water pollution in this process is relatively serious, and the water consumption and drainage are relatively large (generally, more than 300 tons of water per ton of pulp and paper) , the content of organic matter in wastewater is high (PPT reflects: high biochemical oxygen demand (BOD) and high suspended solids (SS)), containing toxic substances that endanger the growth of aquatic organisms and affect industrial, agricultural, animal husbandry and residential water use

Accumulated for a long time, the suspended solids will silt up the river bed port and produce toxic odor of hydrogen sulfide, which will pollute the environment and affect people's lives

[0003] At present, there are still some deficiencies in the existing composite panels for new express boxes produced by using waste cartons, for example; Objects are prone to being wetted by water, which increases the probability of damage to objects inside the composite sheet express box, and reduces the effect of the express box made of composite sheet on the protection of goods, and the existing use of waste cartons to produce new express boxes Composite sheets use The wear resistance is relatively low, which shortens the service life of the express box composite plate
