Embodiment 1

[0045] Making Arundis polylactic acid composite board:

[0046] 1. Collect 1-year-old fresh and mature reed bamboo, then cut it off, split it, and flatten it into a reed bamboo board; cut the reed bamboo section into broken strips, flatten it and process it into a reed bamboo strip, and dry the reed bamboo strip to make it Its moisture content is 8% 10%; Plane and process the dried reed bamboo strips into a flattened reed bamboo board 1;

[0047] 2. Heat the polylactic acid resin masterbatch at a temperature of 175 degrees Celsius and a pressure of 3 MPa for 3 minutes to make a polylactic acid resin film 2 with a thickness of about 0.2 mm;

[0048] 3. Alternately arrange the flattened two-layer reed bamboo board 1 according to 0° / 90° lamination and the two-layer polylactic acid film 2, and place the release cloth on the upper and lower outer layers;

[0049] 4. Put all the above-prepared materials into a flat heat press, preheat at 180 degrees Celsius for 3 minutes, and heat ...

Embodiment 2

[0052] Preparation of Arundis sandwich composite board:

[0053] 1. Collect 1-year-old fresh and mature reed bamboo, then cut it off, split it, and flatten it into a reed bamboo board; cut the reed bamboo section into broken strips, flatten it and process it into a reed bamboo strip, and dry the reed bamboo strip to make it Its moisture content is 8%-10%; planing the dried reed bamboo strips into a flattened reed bamboo board 1;

[0054] 2. Heat the polypropylene resin masterbatch at a temperature of 180 degrees Celsius and a pressure of 3 MPa for 2 minutes to make a polypropylene resin film 2 with a thickness of about 0.2 mm;

[0055] 3. Use wood particleboard with a thickness of 1cm as the interlayer 4. The selection requirements for the interlayer material are: it can withstand a high temperature of about 200 degrees Celsius and a pressure of about 2 MPa;

[0056] 4, the polypropylene resin film 2 is placed between the flattened two-layer reed bamboo board 1 and the middle...

Abstract

The invention belongs to the technical field of composite panels, particularly relates to a bamboo reed composite panel and a forming method thereof, and to be specific, a bamboo reed thermoplastic resin composite panel and a forming method thereof. The bamboo reed composite panel comprises multiple layers of bamboo reed boards and thermoplastic resin films, wherein the thermoplastic resin films and the bamboo reed boards are alternately laminated; the thermoplastic resin films is 1 greater than the bamboo reed boards in layer number; the outermost layer of the bamboo reed composite panel is a thermoplastic resin film. According to the bamboo reed composite panel and the forming method thereof, the bamboo reed boards are manufactured by using mature bamboo reeds which are more than 1 year old, as raw material, and the multiple layers of bamboo reed boards are combined together through molten resin by a hot-pressing technology to prepare the bamboo reed composite panel; the bamboo reed composite panel has very good mechanical properties, and has higher hardness, integrality, plasticity and wear resistance and lower cost compared with the conventional wooden particleboard.

Description

Technical field: [0001] The invention relates to the technical field of composite material boards, in particular to a reed bamboo composite material board and a forming method thereof, more specifically to a reed bamboo thermoplastic resin composite material board and a forming method thereof. Background technique: [0002] Reed bamboo is also called Di Luzhu, River Reed, and Dryland Reed. It is a perennial tall and straight herbaceous plant, resembling a reed in shape. Luzhu has a wide distribution range in my country, from Liaoning in the north to Guangxi in the south, and the largest production is in Jiangsu and Zhejiang. Arundis has good adaptability, is easy to grow and reproduce, and has a higher yield than perennial bamboo and wood. The fiber content of reed bamboo is very high, and the fiber length is relatively large, so it is usually used as an ideal raw material for papermaking. The outer wall tissue of the stem contains many highly silicified cells, which are v...
