PURPOSE: A rock pattern board is provided to express the feeling of a natural granite pattern and reduce weight and manufacturing costs. CONSTITUTION: A cement board(10) is made by mixing cement and water. A reinforcement layer is made by coating the mixture of water, fluoride, surfactant, butyl acrylate, styrene monomer, acrylic acid, hydroxy ethyl acrylate, and acrylonitrile. A barrier layer(20) is made of primer materials. A heat shielding layer(40) is made by coating the mixture of additive, mica pellet, water, and acryl emulsion. A rock pattern layer(50) is coated with composition. An anti-stain layer(60) prevent the contamination due to foreign materials.
