[0062] Preparation of magnesium oxide microspheres loaded with silver:

[0063] Now prepare Ag-MgO microspheres, wherein the molar doping amount of silver is 0.5%.

[0064] Take 10L 1M Mg(NO 3 ) 2 solution and 1L 0.05M AgNO 3 Solution, put into watch glass, place the upper strata of airtight container, get 4Kg mass fraction and be 25% ammoniacal liquor (NH 3 ·H 2 O) Pour into the lower layer of an airtight container. Place the airtight container in a water bath at 50°C to make the lower layer of ammonia water and Mg(NO 3 ) 2 The solution fully reacted for 2h. Afterwards, the watch glass was taken out, and the white precipitate therein was filtered and rinsed three times with deionized water and absolute ethanol respectively. The filter cake was dried in a blast oven at 120 °C for 4 h to obtain magnesium hydroxide and silver hydroxide precursors. The precursor was put into a muffle furnace, heated to 600°C at a rate of 2°C / min and kept for 2h, and then taken out after ...

Abstract

The invention relates to an antibacterial skin-touch paint and a preparation method thereof, the antibacterial skin-touch paint comprises a component A and a component B. The component A comprises 30-45 wt% of a water-based emulsion a, 15-25 wt% of a water-based emulsion b, 15-19 wt% of a magnesium oxide microsphere loaded silver-acrylic resin composite material, 1-4 wt% of a coalescing agent, 0.9-3.5 wt% of a water-based auxiliary agent, 1-4 wt% of water-based color paste and 10-35 wt% of deionized water. The component B is a water-based curing agent and comprises 60-80 wt% of the water-based curing agent and 20-40 wt% of a diluting solvent. According to the present invention, the new antibacterial furniture paint formula can be provided, such that the paint film is safe and non-toxic, and has the rapid sterilization function, and the antibacterial substance in the paint film can still have the long-acting antibacterial property after the paint film is repeatedly wiped. The surface of the paint film is fine and smooth, and the soft and non-sticky skin-friendly feeling is achieved. The color is stable, and the paint film does not obviously turn yellow after long-time use.

Description

technical field [0001] The invention relates to an antibacterial skin-feeling varnish and a preparation method thereof. Background technique [0002] In recent years, the invasion of the new coronavirus has not only made people pay more attention to the spread of this super virus, but also become more sensitive to bacteria that appear anytime and anywhere in daily life. For example, the surfaces of office furniture, dining tables, and cabinets that are in daily contact pay more attention to antibacterial functions. How to ensure that the paint film has a bactericidal function without adding organic fungicides and that the bactericidal substances contained in the paint film are still effective after continuous wiping is the focus and difficulty of antibacterial coatings at present. [0003] Skin-feeling lacquer refers to the strong skin-friendly feeling of the paint film, which can give people a comfortable and warm touch experience. Among them, skin-feeling lacquer has the a...
