Composite waterproof and heat preservation building materials and preparation methods thereof
A composite waterproof and heat preservation building material comprises an upper and a lower water-proof layer 1, 3 and a middle layer of nano-ceramic mycelia thermal insulation. The water-proof layers consist of 50-60 parts expanded perlite, 20-30 parts methyl-sodium and 10-20 parts polyvinyl alcohol. The nano-ceramic mycelia thermal insulation layer consists of 5-8 parts mycelia, 30-50 parts limestone, 15-25 parts nano-ceramic particles and 50-80 parts wheat straw. The nano-ceramic mycelia thermal insulation layer is prepared by crushing the limestone and wheat stone, and limestone powder and the nano-ceramic particles are evenly dispersed in water. Wheat stray powder is added when stirring to adjust moisture and pH of the culture materials. The culture materials are then sterilised. The mycelia and the cultured materials are mixed evenly, moulded and then lowered to a sterile room to culture for 17 days. After the mycelia overgrows the mould, it is then dried at 90°C to obtain the nano-ceramic thermal insulation layer.
