Embodiment 1

[0046] Fluorinated branched compounds are made by the following steps:

[0047] B1. Dissolve 0.1mol of p-hydroxymethylbenzaldehyde and 0.22mol of phenol in glacial acetic acid, cool to 0°C, add dropwise a mixture of 10mL of concentrated sulfuric acid with a mass fraction of 98% and 30mL of glacial acetic acid while stirring, drop After the addition, the reaction was continued at 0°C for 72 hours, then poured into frozen ice water, stirred for 1 hour, filtered, washed with water until the filtrate was neutral, and dried in vacuo to constant weight to obtain 4-hydroxymethyl-4',4'- Dihydroxytriphenylmethane;

[0048] B2. Add 0.12mol of 4-hydroxymethyl-4',4'-dihydroxytriphenylmethane, 100mL of glacial acetic acid, and 4mL of p-toluenesulfonic acid into a three-necked flask with a condensing reflux tube and a stirring magnet, and stir evenly. Use an oil bath to heat the temperature of the reaction system to 61°C. Under stirring, add 0.1 mol of perfluorovaleric acid dropwise with a...

Embodiment 2

[0050] Modified polyurethane resins are made through the following steps:

[0051] S1. Mix 2 mol of isophorone diisocyanate, 1 mol of polyester diol with a relative molecular weight of 1000 and 10 g of dibutyltin dilaurate evenly, and react in a water bath at 78° C. for 2 hours to obtain isocyanate group-terminated polyurethane;

[0052] S2. Under the protection of nitrogen, mix 0.1mol of isocyanate-terminated polyurethane, 2.3g of dibutyltin dilaurate and 70mL of glacial acetic acid, and slowly add 0.21mol of the mixture prepared in Example 1 at 93°C with a constant pressure dropping funnel. The glacial acetic acid solution of the fluorine-containing branched compound was 50mL, and the dropping rate was 2 drops / second. After the dropwise addition, the reaction was continued for 3h, flocculated with 100mL deionized water / methanol, and dried in a vacuum oven at 100°C for 24h to obtain Modified polyurethane.

Embodiment 3

[0054] Modified polyurethane resins are made through the following steps:

[0055] S1. Mix 2 mol of toluene diisocyanate, 1 mol of polyester diol with a relative molecular weight of 1200 and 18 g of dibutyltin dilaurate evenly, and react in a water bath at 78° C. for 2 hours to obtain isocyanate group-terminated polyurethane;

[0056] S2. Under the protection of nitrogen, mix 0.1 mol of isocyanate-terminated polyurethane, 1.8 g of dibutyltin dilaurate and 70 mL of glacial acetic acid, and slowly add 0.22 mol of the mixture prepared in Example 1 at 93°C with a constant pressure dropping funnel. The glacial acetic acid solution of the fluorine-containing branched compound was 50mL, and the dropping rate was 2 drops / second. After the dropwise addition, the reaction was continued for 3h, flocculated with 100mL deionized water / methanol, and dried in a vacuum oven at 100°C for 24h to obtain Modified polyurethane.

Abstract

The invention discloses a preparation method of a furniture cleaning, sterilization and polishing aerosol, which belongs to the technical field of daily-use chemicals. And the preparation method of the glazing aerosol comprises the following steps: step 1, mixing the components of the oil phase uniformly in proportion to obtain a mixed liquid a; step 2, mixing the components of the water phase uniformly in proportion to obtain the mixed liquid a Solution b; Step 3: Put the mixed solution a into an aerosol tank, then fill it with solution b, and then fill it with propellant, so as to obtain a furniture cleaning, sterilization and polishing aerosol. And the present invention utilizes the modified polyurethane resin grafted with fluorine-containing chains as the film-forming component, utilizes the fluorine-containing branched chains to easily migrate to the surface of the film during film formation, forms a layer of fluorine-containing chains, and then utilizes the fluorine-containing chains to Excellent waterproof and anti-fouling properties, and then improve the anti-fouling properties of the protective film; at the same time, the modified chitosan quaternary ammonium salt loaded with silica is used as the bactericidal and antibacterial component, which reduces the migration of the bactericidal and antibacterial component. Improved durability of antimicrobial properties.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a preparation method of a furniture cleaning, sterilization and polishing aerosol. Background technique [0002] Furniture is an indispensable appliance in life. However, during the use of furniture, it will become dirty and lose its luster. At the same time, it will accumulate bacteria, causing the furniture to lose its luster, become old, and lose its texture. The enriched bacteria will pass to the environment through contact. users, endangering the health of users. Therefore, it is necessary to carry out daily and regular cleaning, sterilization and glazing maintenance on the furniture to maintain the luster and texture of the furniture, prolong the service life of the furniture, and reduce the accumulation of bacteria on the furniture. [0003] However, when the existing glazing aerosols clean, sterilize and polish furniture, although they can form a brig...
