Problems solved by technology

[0005] Traditional fiberboard and particleboard manufacturing usually use ordinary urea-formaldehyde resin as adhesive, but due to the special properties of wheat straw, corn stalk, etc., especially its high content of silicon and wax, urea-formaldehyde resin cannot be used for wheat straw, corn stalk and other particles. firmly glued together

Abstract

The invention relates to the technical field of decorating and building materials, in particular to a novel environment-friendly and fireproof biomass board. The board is characterized by comprising the following components in percentage by weight: 65.0-75.0% of biomass packings, 15.0-25.0% of sodium silicate, 5.0-10.0% of sodium fluosilicate and 0.05-1.0% of fiberglass mesh, wherein the biomass packings are wood scraps, wood branches or crop straws. The environment-friendly and fireproof composite biomass board prepared by organically combining the wastes with good impact resistance and nail holding power, such as crop straw fibers or wood fibers, fiberglass with excellent tensile property and inorganic adhesives with unique fireproofness and waterproofness can be widely applied to the household products such as furniture, indoor and outdoor decoration of buildings, advertisement designing, building templates and other special-purpose boards.

Description

Technical field: [0001] The invention relates to the technical fields of furniture, home furnishing and decoration materials, in particular to a novel environmentally friendly and fireproof biomass composite board. Background technique: [0002] In recent years, with the rapid development of China's economy, the domestic demand for lumber is increasing. The country's attitude towards "protecting forest resources" has become increasingly clear. Faced with great challenges, seeking new materials to replace natural wood to develop panels has become the natural choice for the panel market to survive and develop, and "natural biological straw" has become the focus of the panel market with its special advantages of "cheap and good quality, turning waste into treasure" Focus. [0003] In the international board market, high-quality medium-density straw boards have been developed and produced in the 1990s. Its performance is superior to wood particle boards and comparable to ordina...
