A corrugated (or flat) board for a deck of a truck or a container is manufactured by immersing linen and colored calico into a glue composed of carbolic acid, formalin, ammonia liquor, hardening agent, talc, calcium carbonate, zinc oxide and talcum, drying the linen and colored calico, severing the linen and colored calico into desired size, heat-pressing the linen and colored calico into a corrugated or flat shape, and cooling the linen and colored calico, whereby the corrugated or flat board will be of high strength, acid and alkaline resistance, heat resistance, wear resistance, insulation, and brightness and have colored patterns thereon. |
