Corrugated paper special for cold and heat resistant medicine

The invention provides a corrugated paper for cold and heat resistant medicine. Because a corrugated board is coated with a functional coating, and the functional coating contains trichloroethylene, dicyclohexylcarbodiimide, p-methylbenzene sulfonic acid, colloidal graphite, copper oxide powder, 3,4-dimethylpyrazole, magnesium stearate, carbon fiber, cryolite and other components, and then a coating material is prepared by three steps, especially in the last step, a gradually warming and mixing process is adopted, and the processing parameters of each stage are strictly controlled to ensure that all the components can be fully mixed to react, and the expressive ability of the functional coating is enhanced, so that the functional coating can have excellent corrosion resistance, low temperature resistance, good heat retaining property, high temperature resistance, and strong environmental temperature difference shock, thus ensuring that a packaging box assembled by the corrugated papercan have excellent cold a
