Abstract

The invention relates to an environment-friendly antimicrobial odorless healthy latex paint applicable to internal and external wall application. The environment-friendly antibacterial paint is composed of inorganic/nanoparticle modified acrylate emulsion, nano metal oxide, anatase nano titanium dioxide, aluminum oxide, pigment and filler, thickening agent, dispersant, leveling agent and film-forming assistant. By using the dual functions of the inorganic nanoparticle/modified acrylate composite emulsion and nano metal oxide, the paint is endowed with high performance, and has the functions of environment protection, sterilization, air cleaning, deodorization and the like. The paint has the characteristic of excellent application property, and is antimicrobial, ecological and environment-friendly.

Example Embodiment

[0025] Example 1
[0026] The preparation of an environmentally friendly antibacterial and clean flavor latex coating includes the following steps:
[0027] (1) Take 0.60 kg of sodium polyacrylate (GA-40) and 0.50 kg of sodium metaphosphate and disperse in 27.5 kg of deionized water, add 1.0 kg of nano-zinc oxide, 1.2 kg of nano-copper oxide and 1.0 kg of anatase-type nano-titanium dioxide with high-speed stirring. Kg and 0.5 kg of aluminum oxide, mixed for 1 hour.
[0028] (2) Under medium-speed stirring, slowly add 25 kg of rutile titanium dioxide, 6 kg of heavy calcium carbonate, 5 kg of kaolin, 5 kg of talc, and 2-n-octyl-41 isothiazole to the materials in (1). 0.25 kg of lin-3-one benzimidazole, 0.8 kg of glycerin, 0.1 kg of polysiloxane (BYK-022), and 0.25 kg of hydroxyethyl cellulose (ER-4512), stirring at high speed for 0.5 hours.
[0029] (3) Slowly add 35 kg of inorganic nano-titanium dioxide/organosilicon-acrylate composite emulsion, 0.25 kg of BD-3231 leveling agent and the remaining polysiloxane (BYK-022) 0.15 kg, hydroxy Ethyl cellulose (ER-4512) 0.2 kg, continue to stir for 1 hour to obtain the final product. The coating performance test results are shown in Table 1.
