Description

Alfalfa / Plastic Composite Hollow Panel

technical field

The utility model relates to a composite material hollow board, in particular to an environment-friendly composite material hollow board made of natural plant fiber alfalfa, which is suitable for making wall skirts, suspended ceiling boards, door pockets, photo frames and the like.

Background technique

With the improvement of people's living standards, people often use dadoes, ceiling boards, door covers, photo frames, etc. when decorating offices and homes. Traditionally, these products are generally made of wood or plaster, but they are used in production or There are defects of one kind or another in the process of use. For example, a large amount of wood will be wasted in the production process of wooden dadoes, ceiling panels, door covers, and photo frames, which will lead to deforestation, which is not conducive to soil and water conservation and ecological protection, and often requires anti-corrosion. Insect-proof treatment, the process is complicated, easy to produce color difference, easy to aging and cracking, bulky, high cost, etc.; gypsum ceiling board has low strength, easy to crack and fall off, poor decorability, etc. Thereby, it is very necessary to invent a kind of novel hollow plate to replace the above-mentioned products.

Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of resins such as polyethylene, polypropylene, and polyvinyl chloride, and more than 50% of waste plant fibers such as wood powder, rice husk, and straw. New wooden materials, and then plastic processing techniques such as extrusion, molding, injection molding, etc., to produce panels or profiles. It has good processing performance and mechanical strength, water resistance, corrosion resistance, long service life and good coloring performance. Therefore, it has been widely used in construction, packaging, transportation and other fields in recent years.

Alfalfa is an annual or perennial herb and a thin shrub. It is known as the "king of herbage" and is widely introduced and cultivated around the world. The annual output of alfalfa hay in my country is 4 million to 5 million tons, and the source is sufficient. Using alfalfa to make plastic-wood composite decorative panels can not only expand the types of plastic-wood raw materials, but also expand the use of alfalfa, giving full play to the role of alfalfa, a plant that can be both wild and artificially planted. The plastic-wood decorative panels made of alfalfa can emit a faint grass fragrance during use, which increases the comfort and naturalness of people's office and living environments.

Contents of the invention

The utility model is achieved through the following technical solutions:

The alfalfa/plastic composite material hollow board consists of the first layer of plastic-wood horizontal board, the second layer of plastic-wood horizontal board, the third layer of plastic-wood horizontal board, the fourth layer of plastic-wood horizontal board, the fifth layer of plastic-wood horizontal board, the One wood-plastic vertical board, the second wood-plastic vertical board, the third wood-plastic vertical board, the fourth wood-plastic vertical board, the fifth wood-plastic vertical board, the convex wood-plastic curved board and the convex Composed of plastic-wood curved boards; the first layer of plastic-wood horizontal boards, the third layer of plastic-wood horizontal boards, the first plastic-wood vertical boards and the third plastic-wood vertical boards form a rectangular hollow tube, and the first layer of plastic-wood A rectangular hollow tube is formed between the wooden horizontal board, the third layer of plastic wood horizontal board, the third plastic wood vertical board and the fourth plastic wood vertical board; the second layer of plastic wood horizontal board, the third layer of plastic wood horizontal board, An inverted trapezoidal hollow tube is formed between the fourth layer of plastic-wood horizontal boards, the downward convex plastic-wood arc boards and the third plastic-wood vertical boards; the fifth-layer plastic-wood horizontal boards, the second plastic-wood vertical boards, The left hollow tube with arc edge is formed between the plastic-wood curved board and the upward convex plastic-wood curved board; the fifth layer of plastic-wood horizontal board, the fifth plastic-wood vertical board, the downward convex plastic-wood curved board and the upper A right hollow pipe with arc edges is formed between the convex plastic-wood arc plates.

The plastic is one of polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS plastic.

The alfalfa/plastic composite material hollow plate can be made through plastic processing techniques such as extrusion, molding, injection molding, etc., which is convenient to manufacture and low in cost. Compared with wooden decorative panels, it does not use wood, does not need to cut down forests, has good waterproof performance, does not require anti-corrosion and insect-proof treatment, is not easy to age and crack, does not have color difference, and is light in weight; compared with gypsum decorative panels, it has high strength and rigidity. Large, strong designability, not easy to crack and fall off, good decorability, waterproof and moisture-proof, etc.
