Problems solved by technology

Due to the excessive stress and poor flexibility of the coating film after curing, the paint film is easy to wear and tear, such as Chinese Patent Publication No. CN103059254A, the existing solvent-based paint uses xylene as a solvent, and after the xylene volatilizes, the paint film Formation, because it contains excessive xylene and formaldehyde, the painted floor needs to be ventilated for a long time to volatilize the residual xylene, which is very harmful to the human body and can cause asthma, etc., and its wear resistance and hardness are relatively high Poor, not resistant to scratches; poor gloss retention, the paint surface is easy to turn yellow, such as Chinese Patent Publication No. CN101555380A

Embodiment 1

[0020] 1) Preparation of active nano-calcium silicate: Weigh 20g of nano-calcium silicate and place it in a ball mill, add 2% modifier silane coupling agent F-5, modify it at 600r / min ball mill speed for 40min to obtain The powder is the active nano-calcium silicate.

[0021] 2) Preparation of wear-resistant and bactericidal floor paint: Take nano-silver-loaded silica, nano-activated carbon and the above-mentioned activated nano-calcium silicate with a mass ratio of 1:2:1.5, and mix and stir for 10 minutes in a high-speed mixing mixer to obtain nano-resistant Grinding bactericidal powder, mixing 35 parts of nanometer wear-resistant bactericidal powder with 2 parts of wetting agent, 2 parts of dispersant, 0.4 part of defoamer, 0.8 part of antifungal agent, 0.7 part of antiaging agent, and 2.8 parts of film forming agent Mix and stir 5 parts of additives in a high-speed dispersion mixing mixer for 15 minutes to obtain a mixed nano-wear-resistant bactericidal powder, and then add...

Embodiment 2

[0023] The preparation method of this embodiment is the same as that of Example 1, except that 40 parts of nanometer wear-resistant bactericidal powder and 10 parts of auxiliary agent are used.

Embodiment 3

[0025] The preparation method of this example is the same as that of Example 2, except that the water-based polyurethane-acrylate emulsion has a solid content of 40%, 20 parts of other fillers, and a particle size of 300 mesh.

[0026] The performance test of the floor paint prepared by the embodiment is as follows: the conventional performance adhesion of the floor paint is according to GB / T9286-1998, and the hardness is according to GB / T6739-2006. According to the "Disinfection Technical Specification" released in 2016 by the Ministry of Health And according to the "GB15982-2012 Hospital Disinfection Hygienic Standard" sampling results.

[0027]

[0028]

[0029] Considering comprehensively, the performance of embodiment 2 is better.

Abstract

The invention discloses wear-resistant antibacterial floor paint, comprising, by weight, 100 parts of waterborne polyurethane-acrylate emulsion, 35-40 parts of nano wear-resistant antibacterial powder, 5-10 parts of an aid, 10-15 pars of an environment-friendly pigment, and 10-20 parts of other filling materials, the nano wear-resistant antibacterial powder is composed of activated nano calcium silicate, nano silver-loading silicon dioxide and nano activated carbon in a mass ratio of 1:(1.5-2):(1-1.5), and the prepared floor paint has wear resisting, sterilizing and deodorizing effects.

Description

technical field [0001] The invention specifically relates to a wear-resistant and bactericidal floor paint, which belongs to the technical field of paint manufacturing industry. Background technique [0002] Floor paint is a floor coating used for building interior floor coating finishes. There are two types of floor paints commonly used at present: water-based paints and solvent-based paints. Water-based paint uses water as a solvent, and after the water evaporates, a paint film is formed. Due to the excessive stress and poor flexibility of the coating film after curing, the paint film is easy to wear and tear, such as Chinese Patent Publication No. CN103059254A, the existing solvent-based paint uses xylene as a solvent, and after the xylene volatilizes, the paint film Formation, because it contains excessive xylene and formaldehyde, the painted floor needs to be ventilated for a long time to volatilize the residual xylene, which is very harmful to the human body and can ...
