Embodiment 1

[0039] 1. Raw material ratio (weight)

[0040] Dried wormwood leaves 40%

[0041] Charcoal Powder 35%

[0042] Wood fiber 20%

[0043] Methylcellulose 5%.

[0044] 2. Preparation method

[0045]Weigh the raw materials according to the above ratio. The dry leaves of wormwood are crushed to obtain the dried leaves of wormwood fibers; wood fiber raw materials are decomposed, washed and concentrated to obtain a 6.5% slurry, and the slurry is fed into a refiner for refining, and the beating degree is controlled to be about 33°SR. The wood fiber slurry is obtained: dry leaf fiber of wormwood, wood fiber slurry, charcoal powder (100 meshes in particle size, 10% ash content, moisture≤10%), methyl cellulose, mixed and refined. The sheet-like wormwood plant fiber mosquito-repellent incense base material made by copying is about 3mm thick. Dehydration under 20MPa pressure for 40 minutes, and then stamped into spiral plant fiber mosquito coils with a mold. Dry and dehydrate at 65°C...

Embodiment 2

[0047] 1. Raw material ratio (weight)

[0048] Dried wormwood leaves 30%

[0049] Bamboo Charcoal Powder 50%

[0050] Waste Newspaper Fiber 10%

[0051] Methylcellulose 10%.

[0052] 2. Preparation method

[0053] Weigh the raw materials according to the above ratio. Crush the dried leaves of wormwood to obtain the dried leaves of wormwood fibers; the waste newspaper fiber raw materials are decomposed, washed and concentrated to obtain a 5% slurry, and the slurry is put into a refiner for refining, and the beating degree is controlled to be about 28°SR , to obtain the waste newspaper fiber slurry; the dried leaf fiber of wormwood, the waste newspaper fiber slurry, bamboo charcoal powder (80 orders of particle size, 8% ash content, moisture≤10%), methyl cellulose, mixed and refined. The sheet-like wormwood plant fiber mosquito-repellent incense base material made by copying is about 2.5mm thick. Dehydration under 20MPa pressure for 30min, and then stamped into spiral plan...

Embodiment 3

[0055] 1. Raw material ratio (weight)

[0056] Dried wormwood leaves 50%

[0057] Charcoal Powder 30%

[0058] Wood fiber 5%

[0059] Waste Newspaper Fiber 14%

[0060] Methylcellulose 1%.

[0061] 2. Preparation method

[0062] Weigh the raw materials according to the above ratio. The dry leaves of wormwood are smashed to get the dry leaves of wormwood fibers; wood fiber and waste newspaper fiber raw materials are obtained by dispersing, washing, and concentrating to obtain 8% slurry, and the slurry is entered into a refiner for pulping, and the beating degree is controlled to be about 35°SR to prepare plant fiber slurry; by weight percentage, take dried wormwood leaf fiber, plant fiber slurry, charcoal powder, and methyl cellulose, and mix and refine. The sheet-like wormwood plant fiber mosquito-repellent incense substrate made by copying is about 3.5mm thick. Dehydration under 20MPa pressure for 60 minutes, and then stamped into spiral plant fiber mosquito coils with...

Abstract

The invention relates to mosquito-repellent incense, in particular to artemisia grass plant fibre mosquito-repellent incense and a preparation method thereof. The mosquito-repellent incense comprises a mosquito-repellent incense blank material and a mosquito-repellent medicament, wherein the mosquito-repellent incense blank material comprises the following raw materials, by weight percent: 30-50%of artemisia grass dry leaf, 30-50% of charcoal powder, 10-30% of plant fibre and 1-10% of methyl cellulose. The mosquito-repellent incense contains natural plant mosquito-repellent active componentsand can obviously lower the use quantity of the charcoal powder in the mosquito-repellent incense. The method comprises the procedures of fibre pulping, stirring, stir-frying, dewatering, drying, medicament spraying and the like. The method is simple and easy, is suitable for industrialized production, reduces the injury to the body of an operator and reduces the influence on the environment.

Description

technical field [0001] The invention relates to a mosquito-repellent incense, in particular to a plant fiber mosquito-repellent incense containing mugwort components and a preparation method thereof. Background technique [0002] Since the 20th century, the Japanese Shangshan Matsusan used the Archimedes spiral and the Chinese Yin-Yang gossip principle to make spiral-shaped mosquito-repellent incense. Its low price has occupied a leading position in my country's household hygiene insecticide market. At present, the traditional disc-type mosquito-repellent incense is all with carbonaceous powder (charcoal powder or bamboo charcoal powder), and wood powder (fir powder, wood powder etc.) is added binding material (elm bark powder, bakelite powder, α-starch, Methyl cellulose), antifungal agent, flame retardant, flame retardant, etc. are formed by spraying after homogenization, stirring and blending, extrusion, stamping and drying. Because the particle size of carbonaceous powde...
