Problems solved by technology

Reed particleboard is made by drying and crushing reeds, and the strength and toughness of the reed stalk itself are destroyed. Although the pressed particleboard is light and cheap, its strength is low. Making full use of the strength of the reed stalk itself to make boards has become a solution One way of current reed particleboard disadvantages, but there is no related product yet
Furthermore, although the boards made of plant fibers such as woody plants and herbs have certain strength, they still do not have the high strength and strong supporting force of metal boards, and the disadvantages of metal boards are that they are relatively heavy and expensive. From the perspective of economy, environmental protection and reducing the weight of the board, combining the metal board and the plant fiber board is a method that combines the advantages of the two, and is suitable for making a light, cheap, high-strength, easy-to-process, and decorative board. Compared with commonly used wooden boards, reed boards are lighter and more economical, and are good materials for making composite boards

[0028] The method for preparing a reed pole aluminum composite board provided by the present invention has the following specific steps:

[0029] (1) The preparation steps of reed bark include:

[0030] (1a) After removing the leaves of the original reed stalk, select the middle part of the original reed stalk and cut it into sections according to the required length;

[0031] (1b) The reed rod obtained in step (1a) is subjected to surface modification treatment to destroy the silicified and resinous structure of the reed rod surface and improve the adhesion of the reed rod. The surface modification treatment is to The reed rods are soaked in hot water at 90-100°C for 1 to 1.5 hours, or placed in a NaOH solution with a concentration of 0.5 to 1% and a temperature of 40-50°C for 0.5 to 1 hour;

[0032] (1c) After the reed stems treated in step (1b) are dried to a moisture content of 6-8%, the reed stems are gathered side by side, and then rolled and flattened along the stem direction o...

[0047] The steps for preparing the reed pole aluminum composite material are as follows:

[0048] (1) The preparation steps of reed bark include:

[0049] (1a) After removing the leaves of the original reed stalk, select the middle part of the original reed stalk and cut it into 60mm sections;

[0050] (1b) The reed rod obtained in step (1a) is subjected to surface modification treatment to destroy the silicified and resinous structure of the reed rod surface and improve the adhesion of the reed rod. The surface modification treatment is to The reed rods are soaked in hot water at 90°C for 1.5 hours, or placed at a concentration of 0.5%;

[0051] (1c) After the reed stems processed in step (1b) are dried to a moisture content of 6%, the reed stems are gathered side by side, and then rolled and flattened along the stem direction of the reed stems;

Abstract

The invention discloses a reed rod aluminum plate composite board and a manufacture method thereof. Different from the traditional method that a wood shaving board is made after reeds are smashed, the reeds stems are directly ground, adhered and rolled into reed stem shells for lamination, and then the reed stem shells are laminated into a reed rod composite layer. The structural strength of the reed stems is sufficiently maintained, and the defect that the strength of a composite board made through the smashing processing mode is low is overcome. According to the composite board, the reed stem composite layer is adhered to an aluminum base plate, and a waterproof board wraps the reed stem composite layer, so that interlamination sliding or coming-off of the reed stem composite layer after long time utilization are avoided, the reed stem composite layer is prevented from deteriorating and being rotted due to the fact that the reed stem composite layer is affected with damp, and the composite board which is light, large in strength, endurable and capable of protecting the environment is obtained.

Description

Technical field [0001] The invention relates to a reed pole aluminum composite board and a preparation method thereof. Background technique [0002] Under the current general direction of protecting forests and trees in environmental protection, herb fiber is used in papermaking and building materials industries instead of wood fiber, which is an economical and effective choice. Reed is also widely used as a material that is easy to grow, easy to plant, and inexpensive. But most of them are used in papermaking, and in building materials applications, they are mostly used as pastoral-style decorations or used to make particleboard. Reed particleboard is made by pressing reeds after drying and crushing. The strength and toughness of the reed rods are destroyed. Although the pressed particleboard is light and cheap, the strength is low. It is a solution to make full use of the strength of the reed rods. At present, reed particleboard is a way of shortcomings, but there is no relate...
