Benefits of technology

This patented new type of insulating construction material made up of recycled cellulosic fibrous biomass was developed earlier than previous methods due to its ability to absorb water compared to traditional plaster board products while maintaining durability over longer periods (up to 50 years). Additionally, this new design allows for easier handling when producing thin sheets of thermoplastic resin instead of solid blocks. Overall, these technical improvements improve energy efficiency and lower costs associated with current constructions.

Problems solved by technology

This patented technical problem addressed in this patent relates to finding ways to efficiently recycle excessively discarded chrome water containing various types of organic solvent residues called chromium rubble sludge during the extraction of collagens from wet red belting waste without causing damage to surrounding ecosystems like lakes and rivers due to its complex nature.

Abstract

The invention discloses an environment-friendly building material and a preparation method thereof, and relates to the field of novel building materials. An intermediate layer of the environment-friendly building material is a collagen fiber net; an upper layer and a lower layer are woven fabric; a collagen fiber is extracted from wet blue leather waste. According to the preparation method of a collagen fiber thermal insulation material, the collagen fiber thermal insulation material with good service strength is prepared through simplifying and shortening extraction of the collagen fiber from the wet blue leather waste and a net-forming reinforcing process; the effects of using the collagen fiber in the blue wet leather waste and utilizing the collagen fiber in the blue wet leather waste at low cost on a large scale are reached; on one hand, the burden of the waste is relieved for leather-making enterprises, and a good method is provided for changing waste into treasures; on the other hand, a plurality of advantages that dermal collagen fibers are moisture-absorbing, breathable, lightweight, warm in winter and cool in summer, flame-retardant and the like are fully utilized, the building material is convenient to install on the spot, and is an environment-friendly building material; and an ideal choice is provided for pursuing environment-friendly and comfortable modern architecture.
