Problems solved by technology

[0003] However, the products currently on the market using crop residues, including artificial wood boards, straw tiles, straw tableware, etc., use chemically synthesized substances as biomass adhesives in the preparation process of these products, and these substances are used in production and use. In the process, a large amount of harmful gas will be produced, which is not conducive to human health; in addition, the existing products produced by using the leftovers of crops do not have the characteristic of texture, and the process of texture treatment needs to be added in the processing process steps, which makes the entire processing steps more cumbersome, and the texture layer added later will be easily damaged with the prolongation of product use time, making the product unusable or needing to be textured again, increasing the cost

Abstract

The invention provides a preparation method of a biomass composite material. The preparation method comprises the following steps: (1) cleaning a biomass material; (2) soaking: soaking the cleaned biomass material in clear water or a coloring agent aqueous solution at room temperature; (3) grinding or weaving and recombining: grinding the soaked biomass material in a grinding machine to obtain fibers with the length of 3-10cm, or weaving and combining the soaked biomass material into an integrated state, and pre-pressing; (4) drying: placing the biomass material obtained in the step (3) in a natural ventilation state for 2-3 days; and (5) mixing: mixing the dried biomass material with a biomass adhesive according to a certain proportion to form an assembly, or brushing a certain amount ofbiomass adhesive on the dried biomass material to form an assembly, namely the biomass composite material. A biomass container or a biomass plate made of the biomass composite material has natural textures and does not contain toxic substances.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and in particular relates to a preparation method and application of a biomass composite material. Background technique [0002] my country is a large agricultural country, with an annual crop output of hundreds of millions of tons, and a large amount of agricultural residues will be generated during the processing of crop products. Most of these agricultural residues are directly discarded or burned on the spot, thus causing environmental pollution. Pollution and data waste, and the development of using agricultural residues as environmentally friendly products in the current industrial production development has been highly valued by people. [0003] However, the products currently on the market using crop residues, including artificial wood boards, straw tiles, straw tableware, etc., use chemically synthesized substances as biomass adhesives in the preparation process of these prod...
