Embodiment 1

[0037] Embodiment 1, a kind of preparation method of range hood dust-proof film, comprises the following steps:

[0038] (1) Purification of konjac glucomannan:

[0039] Preparation of sol: Take 2g of konjac glucomannan and add it to 400mL of distilled water, stir with a stirrer at 150r / min at 60°C for 1h, then let it stand for 2h to form a sol;

[0040] Suction filtration: add 400mL of water to dilute the above sol, then use the suction filtration device of the glass sand funnel to filter at 60°C for 10min, then evaporate at 150r / min for 30min, concentrate at 40-80°C until the water content is 60%, and obtain the sol after suction filtration and concentration Konjac Glucomannan Sol;

[0041] Dehydration: Add 100mL of ethanol with a volume concentration of 95% to 100mL of konjac glucomannan sol concentrated by suction filtration, grind for 0.5h, and precipitate occurs, transfer the precipitate to a beaker, and then wash with absolute ethanol for 3 times ;

[0042] Drying: P...

Abstract

The invention relates to a range hood dustproof film and a preparation method thereof. The preparation method of the range hood dustproof film comprises purification of konjac glucomannan, preparation of modified konjac glucomannan, purification of a modified product, mixing, plate inversion and film preparation, and film opening. The range hood dustproof film takes the konjac glucomannan as a carrier and other auxiliary agents are added, so that the range hood dustproof film has good film forming property, water resistance, antibacterial property, large tensile strength and good flexibility; the product has the antibacterial property and the viscosity performance is very good; the stuck range hood dustproof film is not crimped, has biodegradability and does not pollute the environment. The range hood dustproof film takes the konjac glucomannan as a main material of the range hood dustproof film; compared with a plastic material, the range hood dustproof film has high tensile strength, acid and alkali resistance, high temperature resistance and antibacterial effect, can be completely biodegraded and is environment-friendly and low-carbon, and the materials are easy to obtain.

Description

technical field [0001] The invention relates to a dust-proof film and a preparation method thereof, in particular to a dust-proof film for a range hood and a preparation method thereof. Background technique [0002] Nowadays, range hoods have entered thousands of households. While cleaning the kitchen, they themselves have become a place to hide dirt. With long-term use, range hoods become extremely dirty. Cleaning the range hood can be described as the enemy of housewives. The range hood is one of the essential electrical appliances in the kitchen. A large amount of oil fume generated during cooking will be discharged into the flue through the range hood to ensure the freshness of the air in the kitchen. Dirty land". The cleaning of the range hood is very troublesome, and it cannot be cleaned, especially the oil. Most housewives think that cleaning the range hood is too troublesome. And the cleaning of the range hood is very necessary. After a long time, the range hood w...
