Problems solved by technology

[0002] Ordinary paint uses titanium dioxide in the rutile crystal form as a filler and whitening agent, but after the paint is applied to the wall, due to the photocatalytic effect of rutile titanium dioxide, it will decompose the resin binder in the paint, resulting in paint Powdering, cracking, and falling off reduce the service life; at the same time, because the coating uses a resin binder, it will release formaldehyde and TVOC. In order to eliminate the release of pollutants, some people currently use anatase titanium dioxide as a filler. into the coating to effectively degrade formaldehyde and TVOC. Since the photocatalytic effect of anatase titanium dioxide is stronger than that of rutile titanium dioxide, the durability of the prepared coating is worse than that of rutile titanium dioxide, resulting in photocorrosion

Embodiment Construction

[0024] like figure 1 As shown, the invention discloses a photocatalytic antibacterial, antiviral, formaldehyde-removing and odor-removing coating.

[0025] A photocatalytic antibacterial, anti-virus, formaldehyde-removing and odor-removing coating includes sodium hexametaphosphate, nano-titanium dioxide, dispersant, hydroxyapatite, silane coupling agent, potassium silicate, water, and condensed phosphate, by configuring the above materials , thereby making photocatalytic antibacterial, antiviral, formaldehyde-removing and odor-removing coatings.

[0026] Its preparation method comprises the following steps:

[0027] (1) The sodium hexametaphosphate that quality is 2.5g is dissolved in water, is configured into the sodium hexametaphosphate solution that mass fraction is 25%; The condensed phosphate that quality is 6g is dissolved in water, is configured into mass fraction and is 6% The condensed phosphate saturated solution; The potassium water glass that quality is 45g is di...

Abstract

The invention relates to a coating preparation technology, in particular to a photocatalytic antibacterial and antiviral formaldehyde-removing and odor-removing coating which comprises sodium hexametaphosphate, nano titanium dioxide, a dispersing agent, hydroxyapatite, a silane coupling agent, potash water glass, water and condensed phosphate. The materials are prepared to prepare the photocatalytic antibacterial and antiviral formaldehyde-removing and odor-removing coating, the prepared coating can effectively remove formaldehyde and TVOC in the coating, and the removal rate is 90% or above, so that the coating has a good space purifying function, the bonding and durability of the coating can be kept, and the photocorrosion effect is avoided; therefore, the coating can be applied to wall surfaces of various occasions such as indoors and outdoors.
