Problems solved by technology

[0003] Chinese invention patent CN 110253706A, the bamboo is soaked in the mixed enzyme solution and ultrasonically treated, and then soaked in the modified treatment solution, then the bamboo is bundled and wrapped with a thermal insulation coil, and a steam generator is connected and an antiseptic treatment agent is added to the bamboo. Finally, the bamboo is dried. Although this method can prevent mildew to a certain extent, the bamboo after ultrasonic treatment is not washed, and the broken starch and sugar after ultrasonic treatment adhere to the surface of the bamboo. Mildew is more likely to occur, and the modified treatment solution and preservative added are highly toxic, so it is not suitable for the anti-mildew treatment of bamboo materials for daily-use bamboo products and utensils
Aiming at the problem that the current daily-use bamboo products and utensils are prone to mildew during use, the invention provides an environmentally friendly treatment method for preventing mildew on bamboo

Abstract

The invention discloses an environment-friendly anti-mildew treatment method for bamboo, which comprises the steps of S1 ultrasonic treatment of bamboo to remove green and yellow, the ultrasonic frequency is 50KHz-100KHz, the ultrasonic power is 400-800W, and the ultrasonic temperature is 20-80°C; S2 Use sodium acetate and butylparaben or sodium diacetate and butylparaben or sodium diacetate and propylparaben to prepare compound antifungal agent; S3 uses No. 58 food paraffin, 2‑hydroxy‑1, 4 naphthoquinone, Tween 60 and distilled water are used to configure compound paraffin wax emulsion; the present invention utilizes the thermal effect and mechanical effect of ultrasonic wave to destroy starch and inclusions in bamboo, and combines food-grade anti-fungal agent and food-grade paraffin wax. Bamboo materials can not only be applied to anti-mildew treatment of common daily-use bamboo products such as bamboo barrels, bamboo chopsticks, bamboo cutting boards, bamboo toothbrushes, etc., but also can greatly improve the dimensional stability, mechanical properties, hardness and wear resistance of bamboo materials. and hydrophobicity.

Description

technical field [0001] The invention relates to an environment-friendly anti-mildew treatment method for bamboo, belonging to the technical field of anti-mold treatment for bamboo Background technique [0002] Bamboo has the characteristics of fast growth, degradability, short growth cycle, high yield, and good physical and mechanical properties, so it has great development value. Anti-mildew treatment of bamboo is a very important process in the processing and manufacturing of bamboo daily necessities, bamboo furniture and bamboo engineering materials. Although the existing anti-mildew treatment process has greatly improved aspects of human body and environmental toxicity, it still cannot be used for common daily-use bamboo utensils such as bamboo barrels, bamboo chopsticks, bamboo chopping boards, bamboo toothbrushes, etc. Therefore, it is of great significance to develop a kind of environmentally friendly bamboo mildew-proof treatment method for daily-use bamboo products...
