<p>The present invention relates to a method to manufacture a board for an interior material comprising: a step of generating a composition by mixing a fiber-reinforced plastic hardener and a stone dust mixed solution in the weight ratio of 1:1-5:1; a step of generating a mixture by adding 5-20 parts by weight of flame retardant Styrofoam grains as an additive to 80-95 parts by weight of the generated composition; a step of stirring the generated mixture for 1-2 hours at room temperature-50 degrees Celsius; a step of injecting 50 parts by weight of the mixture into a mold; a step of stacking a mesh net on the upper part of the injected mixture; a step of injecting 50 parts by weight of the rest of the mixture into the upper part of the stacked mesh net; and a step of curing and removing the same.</p> |
