Embodiment 1
[0017] A sound insulation material, mainly made from the following raw materials in parts by weight: 25 parts of cotton rock, 1 part of orange peel, 6 parts of dried lotus root stems and leaves, 3 parts of
[0018] Parts Schima, 6 parts Stuart, 5 parts Jujube, 2 parts polyacrylamide, 10 parts basalt, 10 parts stone, 8 parts chlorine
[0019] Paraffin wax, 5 parts acrylic resin;
[0020] Concrete preparation method comprises the following steps:
[0021] 1) First, the orange peel, dry lotus root stems and leaves, Schima superba, Situya bean wood, and jujube wood are pulverized and processed into granules, and the pulverized granules are mixed and put into a high-pressure container for heat treatment with steam at a pressure of 5 MPa , soften the particles, partially hydrolyze the carbohydrates, then increase the vapor pressure to 8MPa, keep it for 6 seconds, and then quickly open the valve, and the particles explode into flocculent fibers to obtain flocculent fibers;
