[0027] Example 1
[0028] 1. A preparation method of a straw sheet, the preparation method comprising:
[0029] S1: Puff the straw in an extruder to obtain fibrous straw fine material;
[0030] S2: mixing the fibrous straw fine material with water to obtain a fibrous straw fine material solution, and the mass fraction of the straw in the fibrous straw fine material solution is 5%;
[0031] S3: The fibrous straw fine material solution is made into a wet billet by the copying method;
[0032] The primary layer is formed by dehydration and filtration on the screen surface of the cylinder wheel, and then one primary layer is formed into a thin material layer on the endless felt. After vacuum dehydration, the thin material layer is wound on the rotating forming cylinder to form a wet blank, which passes through the forming cylinder The pressurizing system applies pressure to the wet billet to make it dehydrate and compact;
[0033] S4: Extrusion dehydration: drying the wet billet obtained in...

[0040] Example 2
[0041] 1. A preparation method of a straw sheet, the preparation method comprising:
[0042] S1: Puff the straw in an extruder to obtain fibrous straw fine material;
[0043] S2: mixing the fibrous straw fine material with water to obtain a fibrous straw fine material solution, and the mass fraction of the straw in the fibrous straw fine material solution is 5.5%;
[0044] The obtained fibrous straw fine material solution can be mixed with auxiliary materials 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 blank by a copying method;
[0046] The primary layer is formed by dehydration and filtration on the mesh surface of the cylinder wheel, and then one primary layer is formed into a thin layer on the endless felt. After vacuum dehydration, the thin layer is wound ...
