Embodiment 1

[0028] Preparation of carboxymethyl chitosan quaternary ammonium salt: Disperse 1 part of chitosan (deacetylation degree 95%) into 15 parts of isopropanol to swell for 40min, then slowly add 3.7 parts of 40wt% sodium hydroxide aqueous solution dropwise, dropwise After the addition, the water bath was heated to 45°C and reacted for 1.5 h; 1.3 parts of chloroacetic acid was slowly added dropwise to the reaction system, and the reaction was kept for 1.5 h; after the reaction was completed, the pH was adjusted to neutral, and the precipitate was cooled with anhydrous Ethanol washing, suction filtration to obtain light yellow powder solid; 1 part of light yellow powder solid is dissolved in 8 parts of absolute ethanol, the pH of the system is adjusted to 10, and then 7.5 parts of 50wt% 2,3-epoxypropyl group are slowly added dropwise The trimethylammonium chloride aqueous solution was reacted in a water bath at 75°C for 3 hours. After the reaction, the pH of the system was adjusted t...

Embodiment 2

[0030] A processing method for making large-scale bamboo slips by utilizing side-pressed bamboo boards proposed by the present invention comprises the following steps:

[0031] S1. Saw the side-pressed bamboo board according to the design size, and then finely grind and polish the whole piece to obtain the bamboo board;

[0032] S2, put the bamboo board into the antiseptic solution and vacuumize to 0.09MPa, hold for 30min, then pressurize to 1.2MPa, hold for 15min, take out, and dry until the moisture content of the bamboo board is 10%; wherein, the antiseptic solution includes the following qualities Percentage of raw materials: tebuconazole 0.5%, insecticide 0.1%, carboxymethyl chitosan quaternary ammonium salt 0.2% (prepared in Example 1), lauramidopropylamine oxide 0.5%, fatty alcohol polyoxyethylene Ether AEO-34%, antioxidant propyl gallate 0.01%, antifreeze 0.2%, ethanol 2%, isopropanol 4%, and the balance is water.

[0033] S3. Spray the back cover of the bamboo sheet ...

Embodiment 3

[0039] Compared with Example 2, the difference is only in that the step S2 is different, and the specific differences are as follows:

[0040] S2, put the bamboo board into the antiseptic solution and vacuumize to 0.09MPa, hold for 30min, then pressurize to 1.2MPa, hold for 15min, take out, and dry until the moisture content of the bamboo board is 10%; wherein, the antiseptic solution includes the following qualities Percentage of raw materials: tebuconazole 2.5%, propiconazole 2.5%, insecticide 0.8%, carboxymethyl chitosan quaternary ammonium salt 2% (prepared in Example 1), lauramide propyl amine oxide 2% , fatty alcohol polyoxyethylene ether AEO-5 0.5%, antioxidant tert-butyl hydroquinone 0.05%, antifreeze 2%, propanol 4%, isopropanol 5%, cyclohexane 1%, the balance for water.

Abstract

The invention discloses a processing method for manufacturing a large bamboo slip by using a side-pressed bamboo board, which relates to the technical field of bamboo product processing, and comprises the following steps of: sawing, finely grinding and polishing the side-pressed bamboo board to obtain a bamboo board; the bamboo board is put into preservative liquid for vacuumizing and pressurizing treatment, taken out and dried; wherein the preservative solution is prepared from the following raw materials: a triazole bactericide, an insecticide, carboxymethyl chitosan quaternary ammonium salt, lauramide propyl amine oxide, fatty alcohol-polyoxyethylene ether, an antioxidant, an anti-freezing agent, an organic solvent and water; spraying and brushing the bottom of the bamboo board by using a water-based two-component primer; engraving images and texts; comprehensively polishing with abrasive paper, and then spraying with water-based finish paint; the carved image-text is filled with colors; and polishing with abrasive paper, and spraying water-based finish paint. The large bamboo slip obtained through processing is not prone to cracking when used outdoors, the phenomena of mildew, worm damage and the like can be effectively prevented, and then the stability of the appearance and the size of the large bamboo slip is effectively kept.

Description

technical field [0001] The invention relates to the technical field of bamboo product processing, in particular to a processing method for making large bamboo slips by using side-pressed bamboo boards. Background technique [0002] In modern decoration, as a fast-growing and renewable material, bamboo has the characteristics of high strength, good toughness, easy processing, etc., as well as a long cultural heritage, and is widely used in indoor or outdoor craft accessories, such as outdoor large-scale bamboo slip culture. wall etc. However, bamboo products themselves have the defects of being easy to mildew, moth-eaten, rotten and even cracked, and they need to be treated with antiseptic. However, the anti-mildew effect of the existing bamboo products is not very good, which limits their outdoor use. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing in the background technology, the present invention proposes a processing method for making large...
