By means of the reasonable utilization of volcanic rock and the organic combination with other components, properties such as humidity adjustment, non-slip, mold resistance, thermal insulation and noise reduction of the product are effectively improved, the structural strength thereof is superior to that of other similar products, the cost of the product is low, and the needs of a wide usage range are satisfied; meanwhile, the preparation process of the product only requires slight modification of the existing process, and production investment is low, and thus new uses of volcanic rock are created, and a new self-purification cycle can also be introduced for the environment, satisfying the requirements of green environmental protection.
