Abstract

The invention relates to durable antibacterial water-based acrylic resin, which is prepared from an acrylic acid soft monomer, an acrylic acid hard monomer, a schiff base acrylic acid monomer, acrylicacid, azodiisobutyronitrile, a hydroxyl acrylate monomer, an emulgator, a neutralizer and deionized water through reaction, wherein the schiff base acrylic acid monomer is prepared from salicylaldehyde, R-NH2 and acryloyl chloride through reaction. The invention also provides a preparation method of the durable antibacterial water-based acrylic resin. The durable antibacterial water-based acrylicresin prepared through the method has a favorable adhesive force, high gloss, corrosion resistance and the like, and a high performance cost ratio and wide applicability are achieved; when being usedas an antibacterial coating, the durable antibacterial water-based acrylic resin does not need to add an antibacterial agent, can achieve the effects of lastingly resisting and inhibiting bacteria, and can be used as interior and exterior wall coatings, water-based wood coatings, water-based industrial coatings and the like.

Description

technical field [0001] The invention relates to a modified water-based acrylic resin, in particular to a durable antibacterial water-based acrylic resin and a preparation method thereof, belonging to the technical field of functional resins. Background technique [0002] Due to the wide distribution of microorganisms in the environment, human survival and health have been threatened by various bacteria and viruses for a long time. There are microorganisms on almost all non-biological surfaces, such as: medical care institutions, public places with high risk of infection, stations, hotels, Hotels, airports, bathrooms in humid environments, hot springs and cooling towers, etc. In the above-mentioned sensitive areas, multi-drug resistant bacteria, pathogenic bacteria, and fungi have a tendency to grow; the surface of places where bacteria grow will threaten human health, and it will also affect the actual use value of the surface of the object or cause surface denaturation. An...
