METHOD FOR PROCESSING CONSTRUCTION MATERIALS USING PULP-MINERAL COMPOSITION

摘要

The present invention relates to a method for manufacturing a constructional interior material manufactured by mixing pulp, mineral, and polyolefin resin and extrusion-molding the mixture. A mineral composition comprises: 15-60 parts by weight of the mineral of which main component is calcium carbonate; 3-40 parts by weight of the natural pulp; 28-75.3 parts by weight of the polyolefin resin; and 1.5-4 parts by weight of one or more among an antistatic agent, a forming agent, a coupling agent, a lubricant, a flame retardant, and a dehumidifying agent; thereby providing a constructional interior material capable of being easily formed while having excellent water resistance and printability, high strength in spite of thin thickness, and high flame retardant. Also, the constructional interior material manufactured by the present invention is environmentally friendly and thus can be disposed of without environmental pollution; is suitable for a constructional interior material stored for a long time; and enables mass production at low costs. In terms of a function, the constructional interior material has excellent ultraviolet ray protection, fire resistance, oil resistance, water resistance, damp proof property, flame retardant, and durability.
