Embodiment 1
[0030] The present invention is implemented according to the following steps:
[0031] (1) Plant waste such as rice straw, corn stalk, wheat straw, bamboo and wood processing industry scraps and waste materials, old materials in the packaging industry and publishing industry, waste paper, etc., are subjected to steam explosion treatment and jet crushing treatment to obtain raw material A, The particle size distribution of raw material A is: the mass fraction of plant particles with a particle size of 1 to 100 nanometers accounts for 6%, and the mass fraction of plant particles with a particle size of 0.1 to 100 microns accounts for 94%;
[0032] (2) Steam explosion treatment of old clothes, old quilts, waste leather, waste packaging bags and waste plastic bags to obtain raw material B;
[0033] (3) Prepare a sodium silicate solution with a mass concentration of 15% to obtain raw material C;
[0034] (4) Evenly mix 84% of raw material A, 9% of raw material B, 6% of raw m...
