Embodiment 1

[0037] like figure 1 Shown, a kind of manufacturing method of the reed composite material of this embodiment specifically comprises the following steps:

[0038] S1: Drying of reed segments: process reeds with branches and leaves into reed segments with a length of 1.92 m using a guillotine; then use a conventional mesh belt dryer to dry them at a temperature of 100 °C, and dry them to The moisture content is about 20%, and the dried reed segments are obtained.

[0039] S2: Preparation of the reed unit: Use a flat press to roll the dried reed section, and then use a differential roller to knead it, so that the end surface of the reed section is flat, and there are continuous or discontinuous lines in the length direction. Open the longitudinal cracks so that the fluid can flow freely between the reed nodes and inside and outside the reed, so that the reed unit is obtained, such as figure 2 shown.

[0040] S3: Impregnation and drying of the reed unit: Place the crushed reed...

Embodiment 2

[0048] A method for manufacturing the reed composite material of the present embodiment, specifically comprising the following steps:

[0049] S1: Drying of the reed section: Firstly remove the branches and leaves of the reed manually, and then process the reed stalk into a reed section with a length of 1.5m by using a cross-cut saw; then dry it by superheated steam drying method, and the drying temperature is controlled at At 130°C, dry it to a moisture content of about 18% to obtain dried reed segments.

[0050] S2: Preparation of the reed unit: Roll the dried reed section with a roller press, and then knead it with a differential chain blanket, so that the end surface of the reed section is flat and continuous or discontinuous along the length direction Open longitudinal cracks in the reed so that the fluid can flow freely between the reed nodes and inside and outside the reed, and the reed unit is obtained.

[0051] S3: Impregnation and drying of the reed unit: place the ...

Abstract

The invention discloses a reed composite material. The density of the reed composite material ranges from 0.7 g/cm<3> to 1.3 g/cm<3>. Reeds or reed rods are used as raw materials, the raw materials are processed into reed sections, the reed sections are processed into reed units, then the reed units are subjected to gum dipping, drying, equalization treatment, assembling, solidification forming and aftertreatment, the reed composite material is obtained, the end surfaces of the reed units are flat, and the reed units have open longitudinal cracks in the length direction. The invention furtherprovides a manufacturing method of the reed composite material. The method includes the steps including drying of the reed sections, preparation of the reed units, gum dipping and drying, equalizationtreatment, assembling and solidification forming, later machining treatment and the like. The reed composite material has the advantages that original unit structures of the reeds can be reserved, and the reed composite is high in mechanical strength and good in decoration effect.

Description

technical field [0001] The invention relates to the field of reed-based panels, in particular to a reed composite material and a manufacturing method thereof. Background technique [0002] Phragmites reed is an annual or perennial, renewable plant that mostly grows in low-lying wetlands or shallow water. The area around Dongting Lake is an excellent place for reeds to grow. The Dongting Lake area is rich in reed resources, with an area of ​​more than 1.3 million mu and an annual output of more than 1 million tons. With the implementation of the project of returning farmland to the lake, the reed resources in the Dongting Lake area are constantly increasing. [0003] For a long time in the past, reed resources in the Dongting Lake area were mainly harvested manually and used for papermaking. In recent years, especially in the past 1-2 years, with the continuous strengthening of environmental protection measures, the country and Hunan Province have continuously strengthened t...
