Finished biomass material product and preparation method thereof

Abstract

The present invention discloses a finished biomass material product and a preparation method thereof. The finished biomass material product comprises a first skin layer, an intermediate layer and a second skin layer which are sequentially arranged from top to bottom, the middle layer is a straw layer, and the material of the first skin layer is same to or different from the material of the secondskin layer. The preparation method of the finished biomass material product comprises the following steps: S1, crushing straws used as a raw material to obtain a fine straw material; S2, adding an adhesive to the fine straw material; S3, placing the obtained mixture in a pressing mold, and drying and curing the mixture by a microwave heating process to prepare the straw layer; and S4, respectivelyadhering the first skin layer and the second skin layer to two surfaces of the straw layer coated with the adhesive through the adhesive, and drying the obtained material by a microwave heating process to produce the finished biomass material product. The finished biomass material product and the preparation method thereof have the advantages of simple structure, low cost, effective utilization of agricultural wastes, and promotion of sustainable development of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a biomass material product and a preparation method thereof. Background technique [0002] With the decrease of fossil resources and people's increasing concern about environmental issues, biomass resources, as the only renewable bulk carbon source, are considered to be an important alternative source for large-scale production of renewable fuels and chemicals. my country is a large agricultural country, which produces a large amount of crop straw every year. At present, the main uses of crop straw in my country are returning to the field, raising livestock, fuel and industrial papermaking. However, most of the straw has not been used, some are burned on the spot, and some are stacked in the wild. These unreasonable straw treatment methods not only waste biomass resources, but also seriously pollute the ecological environment. Therefore, the use of crop straws to m...
