Problems solved by technology

[0004] On the other hand, at present, the utilization rate of agricultural waste mainly composed of crop straws in my country is not high. Although the method of returning straws to the field has solved the problem of straw outlets to a certain extent, its utilization value is still relatively low, and for The utilization of other plants such as weeds and waste branches has basically not been realized, which also caused a waste of these resources

preparation example Construction

[0020] The preparation method of the side plate can be as follows: laying a layer of the mixed slurry first, then laying a layer of reinforcing layer on the surface of the laid mixed slurry and pasting the reinforcing layer with the mixed slurry below, and then Lay the second layer of mixed slurry on the reinforced layer. When it is necessary to set more layers of adhesive layer and reinforced layer, cycle in this way until the set number of layers of adhesive layer and reinforced layer is reached, and then carry out natural Curing and drying to shape.

[0021] The core board can be any suitable board material. In order to realize waste utilization, preferably, the core board can use one, multiple or all of the following boards: waste glass steel plate, waste color steel plate, waste hard plastic board, waste rock wool board, waste stone board and foamed cement plate.

[0022] The number of layers of the core board can be one or more layers, and the multi-layer core boards 2...

Abstract

The invention relates to a wood type reinforced light composite board, comprising a core board and two lateral plates respectively positioned at the two sides of the core board, the lateral plates are bonded with the core board to form a whole, wherein at most one lateral plate is a single layer structure and at least one lateral plate is a multi-layer structure, the lateral plate with the singlelayer structure is provided with an adhesive layer and the lateral plate(s) is(are) provided with a plurality of adhesive layers, reinforced layers are arranged between the adjacent adhesive layers, the two sides of the reinforced layers are respectively bonded with the adjacent adhesive layers to form a whole; the reinforced layers are made from net, fabrics or non-woven fabrics, the adhesive layer is obtained by curing mixed slurry, the raw materials of the mixed slurry at least comprises 100 parts by weight of magnesium bonded material and 100-800 parts by weight of agricultural wastes, the magnesium bonded material is composed of magnesium oxide and magnesium salt. The invention can be mainly used as various building boards, industrial boards and daily life boards, so that effective use of agricultural wastes is realized.

Description

technical field [0001] The invention relates to a board, which can be mainly used as various building boards and industrial boards except load-bearing walls. Background technique [0002] There are many forms of building boards other than load-bearing walls, such as gypsum boards used as decorative boards, cement composite boards used as interior wall boards and partition boards, etc., and these boards have their own advantages. It has been effectively applied in a certain field, but there is a common disadvantage, that is, it consumes more natural resources, and as industrial boards such as packing boxes, wood boards are mostly used, which not only consumes a lot of tree resources, but also because the wood board itself It can also be attacked by insects, corrosion, etc., and is easily deformed, which affects the use effect. [0003] Therefore, based on the consideration of environmental friendliness and resource conservation, the recycling of waste materials should be rea...
