Wood-wool reinforced straw stalk board and preparation method thereof

Abstract

The invention discloses a wood-wool reinforced straw stalk board and a preparation method thereof, and belongs to the technical field of artificial boards. The board comprises a surface layer, a corelayer and a bottom layer which are sequentially arranged from top to bottom, wherein the surface layer and the bottom layer are straw stalk layers, the core layer is formed by stacking and placing a plurality of layers of wood-wool straw stalk layers together, wherein each wood-wool straw stalk layer is composed of wood wool and straw stalks, the wood wool are arranged in a directional mode in thewood-wool straw stalk layers, and the wood wool in every two adjacent wood-wool straw stalk layers are perpendicular to each other; and the straw stalks in the wood-wool straw stalk layers are arranged in a gap of the wood wool to play a role in filling. According to the board and the method, a three-layer directional space structure of the wood wool and the straw stalks is constructed to serve as the core layer of the straw board, the wood wool can play a framework supporting role in the plates, a structure with a stable size is formed between the wood wool and the straw stalks, so that thedensity of the straw stalk board is reduced, the consumption of raw materials is reduced, and the light weight of the straw stalk board is realized.

Description

technical field [0001] The invention belongs to the technical field of artificial boards, and in particular relates to a wood wool reinforced rice straw board and a preparation method thereof. Background technique [0002] With the implementation of my country's natural forest protection policy, the forest timber resources available for logging are becoming more and more scarce. However, with the increasing demand for architectural decoration and furniture consumption, domestic timber consumption is increasing rapidly. At the same time, our country produces a large amount of crop straws every year. Some of these straws are burned on the spot, and some are stacked in the wild. These unreasonable straw disposal methods not only waste biomass resources, but also seriously pollute the ecological environment. . Using crop straw as the main raw material to manufacture artificial boards and developing the crop straw straw board industry is an effective way to alleviate the contrad...

AI Technical Summary

Problems solved by technology

However, the main raw material of rice straw board is rice straw, which has the characteristics of scattered sources, difficult collection and strong seasonality, which makes the supply of raw materials difficult to meet large-scale industrial production, and the structure of rice straw board is unstable and easy to deform. Difficult to be widely used in the field of furniture and building materials
