preparation example Construction

[0049] The preparation method of the nano-carbon dots is as follows: crush the tea source material and mix it with ethanol, heat the product to undergo a hydrothermal reaction, and then dry the product to obtain the nano-carbon dots; preferably, the tea source material The mass ratio to ethanol is 1:0.5-5, preferably 1:1-4, such as 1:2 or 1:3; the heating temperature is 150-250°C, and the reaction time is 10-24 h; preferably 180- 230°C, such as 200°C or 210°C.

[0050] In the present invention, when preparing the antibacterial and mildew-proof hygienic incense, sawdust and tea source materials are mixed, pulverized and sieved to obtain a base material, and then the base material is mixed with a solvent to obtain a mixed material. Wherein, sieving adopts 50-100 mesh standard sieve, preferably 50-80 mesh. The solvent is preferably water, and the base material and water are mixed at a mass ratio of 1:0.75-0.95, which facilitates the uniform dispersion and fusion of the materials...

Embodiment 1

[0053] An antibacterial and mildew-proof hygienic incense, comprising the following raw materials in parts by weight: 25 parts of sawdust, 30 parts of tea residue, 12 parts of dextrin, 3 parts of biomass antibacterial and anti-fungal agent, 2 parts of nano-carbon dots, 1 part of high Potassium manganate; the leftovers of tea leaves are: tea stems, tea powder, brewed tea leaves and other materials.

[0054] The preparation method of biomass antibacterial and antifungal agent comprises the steps:

[0055] (1) Select sea oyster shell as biological calcium carbonate, crush it into 2000 mesh fine powder, mix fine powder and acetic acid aqueous solution at a weight ratio of 1:10, take 10 g sea oyster shell powder, 100 ml of 1wt% Acetic acid aqueous solution was added to the reaction kettle and stirred for 10 min;

[0056] (2) Add 1 g of chitosan and stir for 0.5-1 h, then add an appropriate amount of sodium hydroxide solution and continue stirring until the pH of the solution is 7;...

Embodiment 2

[0072] An antibacterial and mildew-proof hygienic incense, comprising the following raw materials in parts by weight: 20 parts of sawdust, 35 parts of tea residue, 15 parts of dextrin, 3 parts of biomass antibacterial and anti-fungal agent, 2 parts of nano-carbon dots, 1 part of high Potassium manganate; the leftovers of tea leaves are: tea stems, tea powder, brewed tea leaves and other materials.

[0073] The method for preparing sanitary incense in Example 2 is the same as that in Example 1, except that when making the biomass antibacterial and antifungal agent, the sea oyster shell in Example 1 is changed to egg shell powder.

Abstract

The invention relates to a biomass antibacterial and mildew-proof agent, an incense stick containing the biomass antibacterial and mildew-proof agent and a preparation method of the incense stick. The preparation method comprises the following steps: crushing biomass containing calcium carbonate, adding an acidic solution, stirring for reaction, adding chitosan, continuously stirring for reaction, adding an alkaline solution to adjust the pH value of the system to 6-8, and filtering and drying the mixture. The antibacterial and mildew-proof incense stick comprises the following raw materials in parts by weight: 20-40 parts of wood chips, 25-50 parts of a tea source material, 10-15 parts of dextrin, 2-4 parts of a biomass antibacterial and mildew-proof agent, 0.5-2 parts of potassium permanganate and 0-2 parts of nano carbon dots. The nano carbon dots are prepared by carrying out hydrothermal reaction on the tea source material. Natural materials are used as a spice source of the incense stick, so that harm caused by traditional chemical spices is avoided, waste resources are recycled, the incense stick is prevented from going mouldy and going bad, and the incense stick has a flame-retardant effect and an anti-counterfeiting effect and is green and safe.

Description

technical field [0001] The invention relates to the technical field of sanitary incense processing, in particular to a biomass antibacterial and antifungal agent, sanitary incense containing the same and a preparation method. Background technique [0002] The full name of hygienic incense is hygienic mosquito-repellent incense, which belongs to mosquito-repellent incense in a broad sense. Although hygienic incense also has a certain effect of repelling mosquitoes, hygienic incense is more focused on the effect of incense. It can make people feel comfortable while removing odors. It does not contain pyrethrins, etc. Element. [0003] Human life is inseparable from the air, and a good air environment can make people healthy physically and mentally. When you are surrounded by the fragrance of tea, you will often feel relaxed and happy, full of green mountains. In daily life, tea stalks, tea dust, and brewed tea leaves are often discarded as useless things, and these waste mat...
