preparation example Construction

[0030] Provide below the preparation method of vacuum cleaner shell inner wall dust-proof coating of the present invention, it may further comprise the steps:

[0031] 1) Add the resin, water-based polyurethane emulsion, polytetrafluoroethylene emulsion and silicone oil into the mixer, mix and stir evenly, raise the temperature to 70-110°C, and continue stirring for 20-60min;

[0032] 2) Cool down to room temperature, add nano zinc oxide powder, nano magnesium oxide powder, filler and coupling agent in sequence, and stir for 1-3h;

[0033] 3) Add deionized water and dispersant in turn, adjust the rotation speed to 1200-1500rpm, and stir at high speed for 40-80min;

[0034] 4) Add dustproof agent A, dustproof agent B and titanium phosphate powder in sequence, and stir for 1-3 hours;

[0035] 5) Add a curing agent and continue to stir for 30-90 minutes to obtain a dust-proof coating for the inner wall of the vacuum cleaner shell.

[0036] When in use, the inner wall of the vac...

Abstract

The invention discloses a dustproof coating for an inner wall of a shell of a dust collector. The dustproof coating for the inner wall of the shell of the dust collector comprises the following raw materials in parts by weight: 10-50 parts of resin, 30-80 parts of aqueous polyurethane emulsion, 5-30 parts of polytetrafluoroethylene emulsion, 15-45 parts of silicone oil, 2-20 parts of nano zinc oxide powder, 2-20 parts of nano magnesium oxide powder, 5-50 parts of a filler, 1-15 parts of titanium phosphate powder, 3-25 parts of a dust-proof agent A, 3-25 parts of a dust-proof agent B, 5-30 parts of a coupling agent, 2-20 parts of a dispersing agent, 1-15 parts of a curing agent and 20-60 parts of deionized water. The dustproof coating for the inner wall of the shell of the dust collector is uniform and stable, and is high in adhesive force; and a coating layer which is formed by coating the inner wall of the shell of the dust collector with the dustproof coating has quite high dustproof property and quite high wear resistance, and can protect the inner wall of the shell of the dust collector well.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaner equipment, in particular to a dustproof coating for the inner wall of a vacuum cleaner shell. Background technique [0002] Vacuum cleaners are widely used in daily life. The working principle of vacuum cleaners is: using a motor to drive the blades to rotate, generating negative pressure in the sealed housing to suck in dust. The outer casing of the vacuum cleaner seals the internal components of the vacuum cleaner and forms protection for the internal components of the vacuum cleaner. Dust is easy to accumulate on the inner wall of the vacuum cleaner shell, which easily affects the use effect of the vacuum cleaner. However, the dustproof performance of the existing vacuum cleaner shells is generally poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dust-proof coating for the inner wall of the vacuum cleaner housing in ...
