Abstract
The invention discloses a processing method for manufacturing a large bamboo slip by utilizing side-pressed bamboo boards, which relates to the technical field of bamboo product processing and comprises the following steps: sawing and cutting the side-pressed bamboo boards, and finely grinding and polishing to obtain bamboo boards; putting the bamboo board into the preservative solution, vacuumizing and pressurizing, taking out and drying; wherein, the preservative solution comprises the following raw materials: triazole bactericide, insecticide, carboxymethyl chitosan quaternary ammonium salt, lauramide propyl amine oxide, fatty alcohol-polyoxyethylene ether, antioxidant, antifreeze agent, organic solvent and water; carrying out bottom sealing and spraying on the bamboo board by using a water-based two-component primer; engraving pictures and texts; sanding the whole surface of the sand paper, and then spraying and brushing the sand paper with the waterborne finish; filling colors into the carved pictures and texts; polishing with sand paper, and spraying water-based finish paint. The large bamboo slip processed by the invention is not easy to crack when being used outdoors, can effectively prevent the phenomena of mildew, worm damage and the like, and further effectively keeps the stability of the appearance and the size.
Description
Technical Field
The invention relates to the technical field of bamboo product processing, in particular to a processing method for manufacturing a large bamboo slip by utilizing side pressure bamboo boards.
Background
In modern decoration, bamboo is used as a fast-growing and reproducible material, has the characteristics of high strength, good toughness, easy processing and the like, and is widely used for indoor or outdoor craft ornaments such as outdoor large bamboo slips culture walls and the like due to long-standing culture. However, bamboo products themselves have the defects of easy mildew, worm damage, rotten holes and even cracking, and need to be subjected to antiseptic treatment. However, the mildew-proof effect of the existing bamboo products is not good, and the outdoor use of the bamboo products is limited.
