Preparation method of inorganic non-metal plate for ocean trade container

The invention relates to the field of composite materials, in particular to a preparation method of an inorganic non-metal plate for an ocean trade container, which comprises the following steps: step 1, mixing Portland cement, aluminate cement, quartz sand, limestone and silica fume according to a preset mass ratio to obtain powder A; 2, quartz sand and calcium hydroxide are mixed according to a preset molar ratio, the mixture is added into water at 120-140 DEG C to react for at least 12 hours, filtering and drying are conducted, and an accelerant A is obtained; 3, the powder A, an accelerant A, fibers, a polymer and water are mixed according to a preset mass ratio, shearing and stirring are conducted, a mixture A is obtained, and the polymer is at least one of polyvinyl alcohol, polyacrylamide and glycerol; and 4, putting the mixture A into a grinding tool, carrying out compression molding, and maintaining for 28 days after molding, so as to obtain the inorganic non-metal plate for the ocean trade container
