Problems solved by technology

[0002] At present, with the continuous improvement of people's daily life standards, people's requirements for the comfort of life are gradually increasing, and the requirements for coatings are more stringent, which makes their houses more beautiful. Wall coverings and wallpapers are popular for interior decoration. , but wall coverings and wallpapers have the following defects: First, they are not environmentally friendly. Wall coverings and wallpapers themselves contain benzene substances, which are harmful to the human body and affect human health. Before pasting ordinary wall coverings and wallpapers, the walls must be Apply an oily primer, and the oily primer contains solvents, additives, additive solvents, etc. These substances contain toluene and xylene, which will cause serious damage to the human respiratory tract. In addition, it must be used when pasting wall coverings and wallpapers. Wall cloth glue, wall cloth glue contains a lot of methanol, methanol is a toxic and volatile substance, and it is also very harmful to the h

Embodiment 1

[0026] 1. Preparation of aggregated particles:

[0027] At a water bath temperature of 75°C, 98g of ethyl acrylate, 50g of butyl methacrylate, 1.5g of γ-methacryloxypropyltriethoxysilane and 25g of ammonium persulfate were continuously added dropwise for 2 hours , allowing the polymerization to proceed.

[0028] After the dropwise addition of the mixed monomers is terminated, the mixture is aged for 3 hours.

[0029] After aging, the reaction solution is cooled to room temperature to terminate the reaction to obtain an aqueous dispersion of the polymer, which is spray-dried to obtain polymer particles.

[0030] 2. Preparation of nano zinc oxide modified chitosan:

[0031] 1) Weigh ZnCl 2 Dissolve in absolute ethanol, add PEG400 as dispersant. After mixing evenly, raise the temperature to 50-60°C, and slowly add a certain amount of ammonia-water-ethanol solution with a volume ratio of (1:1) dropwise under continuous magnetic stirring to form a white precipitate. After drip...

Abstract

The invention discloses a mildew-preventing antibacterial hydrophobic coating and belongs to the technical field of coatings. According to the mildew-preventing antibacterial hydrophobic coating disclosed by the invention, a coarse surface shape can be formed on a substrate by adding polymeric particles, so that the hydrophobic property of the coating is greatly improved; and meanwhile, by taking nano-zinc oxide modified chitosan as an antibacterial agent, the mildew-preventing antibacterial hydrophobic coating disclosed by the invention has a good antibacterial effect and overcomes the defects that silver oxide which serves as the antibacterial agent is active in property, is easily oxidized in air to lead to discolor and is high in cost.
