摘要

Problem to be solved: to provide a construction board having flexibility and flexibility, a method of manufacturing the same, a method for semi permanently increasing the durability of a building plate, and a method of forming a pattern, a character or a figure on the surface of a building plate, and fixing it permanently.A method of forming a mixture of a paste shaped synthetic resin having a viscosity of 79 to 89 weight% of cement, 2.5 to 11.5 weight% of cement, 1 to 3% by weight of a cement accelerator, 2 to 8% by weight of aggregate, and 2 to 3% by weight of an aggregate, and a flame retardant inorganic fiber having a ratio of 0.7 to 3% by weight to form and dry the same And the manufactured plate material is manufactured.Further, a method of improving the durability of the plate material in a semi permanent manner by heating or carbonizing the entire surface or part of a building plate material, a method of forming a predetermined pattern, a character or a figure on the surface of the plate material in a semi permanent manner, and a plate member thereof.Diagram
