Problems solved by technology

However, titanium dioxide can only play an antibacterial role when it is excited by ultraviolet rays, and the food delivery elevator is mostly located indoors, and is often closed, with few light sources, so its antibacterial effect cannot be fully exerted

preparation example Construction

[0033] The preparation method of described antibacterial coating comprises:

[0034] (1) Add 5-15 parts of zinc oxide, 5-15 parts of magnesium oxide, and 5-15 parts of calcium carbonate to 40-60 parts of phosphoric acid solution at 40-60 ° C, stir and react for a preset time to obtain the first mixed solution;

[0035] Calcium carbonate, magnesium oxide, zinc oxide powder is added to phosphate solution to prepare composite phosphate double salt carrier. By controlling the temperature in the range of 40-60°C and the reaction time within 4-6h, it can be prepared with a large specific surface area. Phosphate double salt product, its loading performance is excellent. Can be used as a good carrier for disinfectant silver and diatomaceous earth.

[0036] Preferably, the powders of zinc oxide, magnesium oxide and calcium carbonate can be mixed evenly first, and then slowly added to the phosphoric acid solution at a temperature of 40-60°C. Mixing the powder evenly first can ensure t...

Embodiment 1

[0054] The antimicrobial coating formula is:

[0055] 9 parts of calcium carbonate; 8 parts of zinc oxide, 8 parts of magnesium oxide, 55 parts of phosphoric acid solution, 1.5 parts of silver powder, 10 parts of diatomaceous earth, 10 parts of epoxy resin, 1.5 parts of auxiliary agent; among them, the auxiliary agent is phosphoric acid modified acrylic acid Mixture with bentonite, phosphoric acid modified acrylic resin: bentonite = 3:1.

[0056] The preparation method of antibacterial coating is:

[0057] (1) Stir and mix zinc oxide, magnesium oxide and calcium carbonate in a high-speed mixer according to the formula, then slowly add phosphoric acid solution at a temperature of 45°C, and stir for 5 hours to obtain the first mixed solution;

[0058] (2) Mix the silver powder and the epoxy resin evenly, and ball mill them until the average particle diameter is less than 1 μm to obtain the second mixed solution;

[0059] (3) Cool the first mixed solution to 35°C, add diatomace...

Embodiment 2

[0064] The antimicrobial coating formula is:

[0065] 11 parts of calcium carbonate; 6 parts of zinc oxide, 4 parts of magnesium oxide, 45 parts of phosphoric acid solution, 0.5 parts of silver powder, 0.2 parts of cerium oxide, 14 parts of diatomaceous earth, 20 parts of epoxy resin, 2 parts of additives; It is a mixture of phosphoric acid modified acrylic acid and bentonite, phosphoric acid modified acrylic resin: bentonite = 3:1.

[0066] The preparation method of antibacterial coating is:

[0067] (1) Stir and mix zinc oxide, magnesium oxide and calcium carbonate in a high-speed mixer according to the formula, then slowly add phosphoric acid solution at a temperature of 50°C, and stir for 4.5 hours to obtain the first mixed solution;

[0068] (2) Mix silver powder, cerium oxide, and epoxy resin evenly, and ball mill to grind to an average particle size of <1 μm to obtain a second mixed solution;

[0069] (3) Cool the first mixed solution to 30°C, add diatomaceous earth a...

Abstract

The invention discloses a vegetable delivery elevator. The elevator comprises a car, which comprises a body and an antibacterial coating arranged on the surface of the body; the antibacterial coatingis mainly prepared from the following raw materials in parts by mass: 5-15 parts of calcium carbonate, 5-15 parts of zinc oxide, 5-15 parts of magnesium oxide, 40-60 parts of a phosphoric acid solution, 0.1- 2 parts of silver powder, 10-15 parts of kieselguhr, 5-20 parts of epoxy resin and 2-5 parts of an auxiliary agent. A mode that the antibacterial coating coats the surface of the car is adopted, and the moisture-proof and antibacterial effects of the vegetable delivery elevator are effectively achieved; a disinfecting component compounded by the kieselguhr, cerium oxide and the silver powder is adopted; bacteria can be effectively killed in an environment short of light. Moreover, a reasonable formula system is adopted by the antibacterial coating, and has particularly strong adhesiveforce to a metal matrix; the antibacterial coating is uniformly attached to the surface of the car through a reasonable spraying process, so that the service time of the elevator is long.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a vegetable delivery elevator and a preparation method thereof. Background technique [0002] Food delivery elevators are mostly used for the delivery of food between floors, especially cooked food. Cooked food will produce a large amount of water vapor, which makes the food delivery elevator easy to get wet, resulting in mildew and various bacteria; on the other hand, because the food delivery elevator needs to deliver a large amount of food, it is easy to produce various bacteria; The quality will affect the health of the eaters; therefore, it is very necessary to realize the moisture-proof and anti-bacterial of the food delivery elevator. [0003] An improved method is to directly prepare antibacterial substances as coatings and coat them on the surface of the elevator car. Patent application 201510527775.9 discloses an intelligent elevator, which coats the surface of the elevator ca...
