Problems solved by technology

The existing coatings have developed more perfect functions than before, and traditional coatings do not have antibacterial and antiseptic effects. Although some existing coatings have antiseptic and antiseptic functions, they are generally added by adding some preservatives that are potentially harmful to the human body. To achieve anti-corrosion and anti-bacterial effect, instead of focusing on the anti-bacterial and anti-corrosion effect achieved by the synergy between the components of the coating itself
And its anticorrosion and antibacterial effect of existing anticorrosion coating is not ideal

Abstract

The invention relates to an antimicrobial anticorrosive paint and a preparation method thereof. The antimicrobial anticorrosive paint is prepared from the following raw materials in parts by mass: 66-70 parts of acrylic resin, 16-23 parts of castor oil, 10-13 parts of vinyl acetate, 4-6 parts of dimethyl carbonate, 15-18 parts of nano silicon micropowder, 2-7 parts of polyacrylamide, 1-6 parts of 3-aminopropyltriethoxysilane, 1-4 parts of N-ethyl-para-toluene sulfonate, 5-10 parts of zinc oxide, 2-6 parts of bamboo charcoal powder, 90-100 parts of water, 20-30 parts of ethanol and 10-14 parts of ethyl acetate. By reasonably compounding the acrylic resin and other additives, the paint has excellent antimicrobial and anticorrosive properties and excellent adhesiveness. By adding the N-ethyl-para-toluene sulfonate and 3-aminopropyltriethoxysilane, the paint has excellent adhesive force, impact resistance and water resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antibacterial and antiseptic coating and a preparation method thereof. Background technique [0002] Paint is paint, which is also a kind of material. It can cover the surface of an object, protect and decorate it with all its heart, or play the role of a sign. It can be coated on the surface of an object by different processes to form a firm protective film, which is called lacquer. film or coating. Modern coatings are developing rapidly and are gradually becoming a class of engineering materials with multiple functions. [0003] Paint is a material that uses organic materials or inorganic materials or a mixture of organic and inorganic materials to protect and decorate objects. No matter what kind of coating, it is composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Existing coa...
