Antibacterial and anti-mildew aqueous shell powder and nano-silver coating and production device thereof

Abstract

The invention discloses an antibacterial and anti-mildew aqueous shell powder and nano-silver coating and a production device thereof, and belongs to the technical field of coatings. The aqueous coating comprises modified shell powder, titanium dioxide, nano-silver, an adhesive and water. The production device comprises a reactor, the upper end of the reactor is respectively connected with a solidmixing cylinder and a liquid mixing cylinder, the upper end of the solid mixing cylinder is connected with a feeding bin through a feeding tube, the tail end of the feeding tube is connected with a blowing pump, the bottom and the side surface middle part of the reactor are connected with a circulation pump through communicating pipelines, and the communicating pipeline connected to the top of the circulation pump is provided with a discharge port. The coating has the advantages of low cost, small energy consumption, non-toxicity, good adhesion, good water resistance, good antibacterial property, good mildew resistance and good other comprehensive mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a shell powder nano-silver antibacterial and mildew-proof water-based coating and a production device thereof. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] Indoor paints are mainly divided into two types: water-based paints and solvent-based paints. The main source of pollution is solvent-based paints, and the use of environmentally friendly water-based paints can completely eliminate the worry about paint pollution. Experts from the China Paint Industry Association believe that any solvent-based paint will contain 50% or more organic...

Problems solved by technology

Poor air permeability cannot regulate humidity and remove harmful odors

The cost rises with the price of oil, and the quality of the product declines, so it cannot be directly used for cement lime alkaline walls

Extensive use of petroleum acrylic acid emulsion as base binder and high energy consumption titanium dioxide, high energy consumption, high pollution emissions, high production costs, high resource consumption

Excessive consumption of non-renewable petroleum resources causes high greenhouse gas emissions and climate warming, and man and nature cannot live in harmony. Productivity is unsustainable.

The high investment in the industry is directly proportional to the pollution, wasting energy and destroying the natural ecology, and the earth's environment is overwhelmed

[0005] Moreover, the devices for producing coatings in the prior art are ubiquitous, and the produced coatings are prone to agglomeration, sedimentation, and insufficient reaction of raw materials, etc., which cause the produced coatings to have unsatisfactory effects in actual use.
