Embodiment 1

[0031] Embodiment 1, a kind of preparation method of furniture dust-proof film, comprises the following steps:

[0032] 1. Alkaline modification of konjac glucomannan: Weigh 2g of konjac glucomannan, add 100mL water to a conical flask, stir in a 50°C water bath with a magnetic stirrer at 3000r / min for 10min, and use 0.1mol / L Ca(OH) 2 solution, adjust the pH value to 10, and then stir with a magnetic stirrer at 3000r / min for 1h to obtain deacetylated konjac glucomannan sol;

[0033] 2. Blending: Prepare a glacial acetic acid solution with a weight concentration of 5% to 20%, add chitosan at a weight ratio of 1.5% to 2.5%, stir in a magnetic stirrer at 3000r / min for 10 minutes, and then add the glacial acetic acid solution Stearic acid with a weight ratio of 0.05% to 0.1% to obtain a glacial acetic acid mixed solution, take 70g of glacial acetic acid mixed solution, add 30g of deacetylated konjac glucomannan sol, and mix to obtain a mixed glue. Add 6g of paraffin and 5g of gl...

Abstract

The invention relates to a dustproof film for furniture and a preparation method thereof. The preparation method of the dustproof film for furniture comprises the following steps: performing subtraction modification on konjac glucomannan, blending, degassing, pouring into a plate to make the film and stripping the film. As the konjac glucomannan is used as a carrier together with other additives, the film has excellent filming property, water-tightness and antibacterial property, high tensile strength and good flexibility; as the konjac glucomannan is used as a main material of the dustproof film for furniture, compared with the conventional PVC (Polyvinyl Chloride) material film, the film is high in tensile strength, good in transparency, good in flexibility and high in antibacterial effect. The dustproof film for furniture is superior to an ordinary dustproof film in transparency, and does not damage the original color when adhered to furniture. Besides, the dustproof film for furniture is good in flexibility and is durable; as furniture is frequently touched by people and bacteria are likely to propagate on furniture, the dustproof film also has good antibacterial property, which is very important; and the film can be degraded without causing pollution.

Description

technical field [0001] The invention relates to a dust-proof film and a preparation method thereof, in particular to a furniture dust-proof film and a preparation method thereof. Background technique [0002] As we all know, with the development of the economy, many families have unused furniture. After a long time of unused furniture, the furniture will be covered with dust, especially in places that are difficult to clean. Secondary pollution by dust results in poor cleanliness; many office workers have no time to clean furniture. Like this, it is necessary to develop furniture dust-proof film. [0003] The application number is 201220076224.7 utility model patent "composite dust-proof film"; introduces a composite dust-proof film composed of dust-proof layer, moisture-proof layer, heat-sealing layer and support layer, which is characterized in that a heat-sealing layer is arranged on the support layer, A moisture-proof layer is set above the heat-sealing layer, and a du...
