Embodiment 1

[0017] The preparation of embodiment 1 special-purpose cleaning liquid for whiteboard

[0018] Preparation of β-cyclodextrin inclusion compound: Add dropwise a mixture of 0.2g wormwood oil, 0.1g atractylodes oil and 0.1g clove oil to a saturated aqueous solution of 0.8g β-cyclodextrin at a temperature of 38°C, and include After 15 hours, the temperature was lowered to 4° C. to precipitate for 30 hours, and the precipitate was collected, washed and dried to obtain the β-cyclodextrin inclusion compound.

[0019] Mix and stir 46g of absolute ethanol, 23g of deionized water, 6g of sodium lauryl sulfate, 8g of ethylene glycol, 0.08g of essence, and 1.2g of β-cyclodextrin inclusion compound for 30 minutes to obtain the product of the present invention. The time interval between the addition of each substance is 2 min.

[0020] The obtained whiteboard marker cleaning solution can quickly remove the whiteboard marker writing and has an aromatic smell.

Embodiment 2

[0021] Embodiment 2: Preparation of special cleaning solution for whiteboard

[0022] Preparation of β-cyclodextrin inclusion compound: Add dropwise a mixture of 0.4 g of wormwood oil, 0.2 g of herb oil and 0.1 g of clove oil into a saturated aqueous solution of 1.4 g of β-cyclodextrin at a temperature of 40° C. After 18 hours, the temperature was lowered to 4° C. to precipitate for 36 hours, and the precipitate was collected, washed and dried to obtain the β-cyclodextrin inclusion compound.

[0023] Mix and stir 50g of absolute ethanol, 26g of deionized water, 8g of sodium lauryl sulfate, 8g of ethylene glycol, 0.5g of essence, and 2.1g of β-cyclodextrin inclusion compound for 30 minutes to obtain the product of the present invention. The time interval between the addition of each substance is 5 min.

[0024] The obtained whiteboard marker cleaning solution can quickly remove the whiteboard marker writing without leaving traces.

Embodiment 3

[0025] Embodiment 3: Preparation of special cleaning solution for whiteboard

[0026] Preparation of β-cyclodextrin inclusion compound: Add dropwise a mixture of 0.6g wormwood oil, 0.4g atractylodes oil and 0.2g clove oil to a saturated aqueous solution of 2.3g β-cyclodextrin at a temperature of 42°C, and inclusion After 18 hours, the temperature was lowered to 4° C. to precipitate for 36 hours, and the precipitate was collected, washed and dried to obtain the β-cyclodextrin inclusion compound.

[0027] Mix and stir 65g of absolute ethanol, 25g of deionized water, 7g of sodium lauryl sulfate, 8g of propylene glycol, 0.09g of essence, and 3.5g of β-cyclodextrin inclusion compound for 30 minutes to obtain the product of the present invention. The time interval between the addition of each substance is 4 minutes.

[0028] The obtained whiteboard marker cleaning solution can quickly remove the writing on the whiteboard marker without leaving traces and has an aromatic smell.

Abstract

The invention provides cleaning fluid special for erasing small carbon black grains on a white board. The cleaning fluid comprises the following components by weight percent: 45%-70% of absolute ethyl alcohol, 5%-10% of a surfactant, 7%-13% of an organic solvent, 0.5%-3.5% of beta-cyclodextrin inclusion compound and 15%-30% of deionized water. The cleaning fluid is capable of effectively removing the small carbon black grains permeated into the white board gaps, cleaning the white board and prolonging the service life; wormwood oil, rhizoma atractylodis oil and clove oil are contained in the cleaning fluid, so that the sterilizing effect can be achieved; the cleaning fluid also can be used under a colder environment.

Description

technical field [0001] The invention relates to teaching utensils, in particular to a special cleaning solution for wiping small carbon black particles on a whiteboard. Background technique [0002] The school's teaching blackboard writing tools traditionally use chalk blackboard writing. Dust flies up when wiped after writing, polluting the teaching environment and affecting the health of teachers and students. After that, the whiteboard gradually replaced the ordinary blackboard, and whiteboard pens were used for writing and whiteboard erasers were used for erasing. At present, most of the whiteboard erasers on the market are made of velveteen fabric, and they are often cleaned with water during the wiping process. Since the whiteboard markers used for writing contain small particles of carbon black, it will penetrate into the gaps of the whiteboard, and water has no effect on it. If things go on like this, small carbon black particles will gradually accumulate, resulting...
