Embodiment 1

[0028] 1. A preparation method of straw sheet, said preparation method comprising:

[0029] S1: Expand the straw in an extruder to obtain fibrous straw fines;

[0030] S2: Mixing fibrous straw fines and water to obtain a fibrous straw fines solution, the mass fraction of straw in the fibrous straw fines solution is 5%;

[0031] S3: making the fibrous straw fine material solution into a wet billet by the extraction method;

[0032] The first layer is formed by dehydration and filtration on the mesh surface of the cylinder wheel, and then one of the first layers forms a thin material layer on the endless felt. After vacuum dehydration, the thin material layer is wound on the running forming cylinder to form a wet billet, which passes through the forming cylinder. The pressurization system exerts pressure on the wet billet to make it dehydrated and dense;

[0033] S4: extrusion dehydration: drying the wet base obtained in step S3 by extrusion dehydration;

[0034] S5: Hot pres...

Embodiment 2

[0041] 1. A preparation method of straw sheet, said preparation method comprising:

[0042] S1: Expand the straw in an extruder to obtain fibrous straw fines;

[0043] S2: Mixing fibrous straw fines and water to obtain a fibrous straw fines solution, the mass fraction of straw in the fibrous straw fines solution is 5.5%;

[0044] The obtained fibrous straw fine material solution can be mixed with an auxiliary material selected from one or more of wood fiber, bamboo fiber or chemical fiber; the mass ratio of the auxiliary material to the straw fiber is 1:6.

[0045] S3: the fibrous straw fine material solution mixed with auxiliary materials in step S2 is made into a wet billet by a copying method;

[0046] The first layer is formed by dehydration and filtration on the mesh surface of the cylinder wheel, and then one of the first layers forms a thin material layer on the endless felt. After vacuum dehydration, the thin material layer is wound on the running forming cylinder to ...

Embodiment 3

[0056] 1. a preparation method of straw thin board, is characterized in that, described preparation method comprises:

[0057]S1: Expand the straw in an extruder to obtain fibrous straw fines;

[0058] S2: Mixing fibrous straw fines and water to obtain a fibrous straw fines solution, the mass fraction of straw in the fibrous straw fines solution is 6%; the obtained fibrous straw fines solution can be mixed with auxiliary materials The auxiliary material is selected from one or more of wood fiber, bamboo fiber or chemical fiber; the mass ratio of the auxiliary material to straw fiber is 1:7;

[0059] S3: the fibrous straw fine material solution mixed with auxiliary materials in step S2 is made into a wet billet by a copying method;

[0060] The first layer is formed by dehydration and filtration on the mesh surface of the cylinder wheel, and then one of the first layers forms a thin material layer on the endless felt. After vacuum dehydration, the thin material layer is wound ...

Abstract

The invention discloses a thin straw plate and a manufacturing method of the thin straw plate. The manufacturing method of the thin straw plate comprises the steps that S1, straw is expanded in an expanding machine, so that fibrous straw fine materials are obtained; S2, the fibrous straw fine materials and water are mixed, so that a solution is obtained, wherein the mass percentage of straw in thefibrous straw fine material solution ranges from 5% to 6%; S3, the fibrous straw fine material solution is mixed with an auxiliary material, wherein the auxiliary material is one or more fibers selected from wood fibers, bamboo fibers and chemical fibers; S4, the fibrous straw fine material solution is processed according to a hatschek process to form a wet blank; S5, extrusion and water removalare conducted; S6, hot-press forming is conducted; and S7, press polishing is conducted. According to the thin straw plate and the manufacturing method of the thin straw plate, the straw serves as theraw material, all chemical components are not added, energy saving and environmental protection are achieved, the cost of the straw is low, and the straw is a renewable resource. The thin straw plateis quite high in degradability, and cannot bring the additional burden for the environment. In addition, the thin straw plate is high in surface smoothness and can be widely applied to production ofpaper tubes and the like.

Description

technical field [0001] The invention relates to the technical field of building and furniture boards, in particular to a straw thin board and a preparation method thereof. Background technique [0002] At present, due to the protection of the environment and forest resources in various countries, the use of wood-based panels is gradually restricted, but the demand for wood-based panels in society is increasing. Therefore, people are paying more and more attention to the issue of wood substitutes. However, kraft paper, paper tubes, etc. are still widely used in the market at present, and the source of raw materials is limited and the cost is high. Wheat straw is a renewable resource, and a large amount of wheat straw is produced every year. In some economic areas, it will be burned by people, which causes a kind of pollution and wastes resources. Increasing its economic added value has become a problem that needs to be solved urgently. . Therefore, it is one of the effectiv...
