Problems solved by technology

[0003] At present, coatings are widely used in construction, vehicles, military, decoration, and shipbuilding industries, and are closely related to people's lives. With the continuous development of science and technology, there are various types of coating materials. In recent years, the research and application of coatings have become more and more important. Widely, especially indoor coatings, antibacterial requirements are also added to the performance requirements, but the coatings on the market now have general antibacterial properties, are easy to attach dust, and have a low service life. Some coatings have a short anti-aging period, more or less There are few defects such as easy aging, peeling, easy falling off, discoloration, poor weather resistance, poisonous and smelly, inconvenient construction, etc.; and its service life is short when it is outside the building

Abstract

The invention discloses an antibacterial and bactericidal material for a coating. The antibacterial and bactericidal material for the coating is prepared from the following raw materials: modified nano zinc oxide, a thickening agent, dipotassium glycyrrhizinate, an activating agent, chitosan, polydiallyl dimethyl ammonium chloride and deionized water. The antibacterial and bactericidal material for the coating has excellent antibacterial and bactericidal performance, has good killing capacity on various bacteria and viruses such as escherichia coli, staphylococcus aureus, bacillus subtilis, salmonella and pseudomonas aeruginosa, and is excellent in anti-aging performance; the antibacterial and bactericidal material can play good antibacterial and bactericidal effects and anti-aging effectsonly by adding 2% of the antibacterial and bactericidal material into the coating and can effectively save the cost and has wide application; the antibacterial and sterilizing performance and the anti-aging performance of the antibacterial and sterilizing material for the coating are remarkably improved by modifying the nano zinc oxide and adding the activating agent.

Description

Technical field [0001] The invention relates to the technical field of paint additives, in particular to an antibacterial and sterilizing material for paint, and a preparation method and application thereof. Background technique [0002] The controllable synthesis of nanomaterials is an important research content in modern materials science. The selection and dosage of surfactants are very important for the properties of nanoparticles to reduce the aggregation degree of particles in the dispersion system and keep the dispersion system relatively stable. Nanomaterials have a very large specific surface area. The number of surface atoms, surface energy and surface tension increase sharply with the decrease of particle size. Small size effects, surface effects, quantum size effects, and macroscopic quantum tunneling can lead to nanoparticle Heat, magnetism, light, sensitivity and surface stability are different from conventional particles. [0003] At present, coatings are used in la...
