Problems solved by technology

[0004] The antibacterial principle of the existing antibacterial coating is to mix the antibacterial agent and the antibacterial coating mechanically to prepare the antibacterial coating. This antibacterial coating has a disadvantage, because the antibacterial molecular formula is mechanically mixed into the coating, and the antibacterial molecules are usually water-soluble substances. , when the paint is in contact with water or during the wiping process, antibacterial molecules are easy to escape from the paint into the water, so as the use time increases, the antibacterial effect of the paint continues to decline

Abstract

The invention provides an environment-friendly coating additive with an antibacterial function. The environment-friendly coating additive is characterized by being prepared from the following components in parts by weight: 15-18 parts of calcium carbonate, 15-20 parts of sepiolite, 10-14 parts of hollow ceramic microbeads, 6-15 parts of magnesium silicate, 6-9 parts of nano zinc oxide, 11-16 partsof butyl acrylate, 11-32 parts of tributyl phosphate, 3-8 parts of hydroxyethyl cellulose, 2-3 parts of sodium alginate, 4-6 parts of flame retardant, 1-9 parts of mildew preventive, 20-35 parts of polyethylene quaternary ammonium cations and 1-3 parts of photoinitiator. The antibacterial additive has the advantages that the polyethylene quaternary ammonium cations are chemically bonded with long-chain resin, so that the polyethylene quaternary ammonium cations cannot overflow from a coating layer, and therefore a coating is excellent in antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of paint additives, in particular to an environmentally friendly paint additive with antibacterial function and a preparation method thereof. Background technique [0002] Paint is a fluid or powdery substance that can evenly cover and adhere well to the surface of an object to form a solid film. He is a material with protective decoration or special functions. According to the dispersion state of film-forming substances and pigments, there are solvent-based coatings, water-based coatings, powder coatings, etc. [0003] With the development of society, people's daily life, that is, buildings, ships, circulating cooling water and many other fields have antibacterial needs. Therefore, the development of coatings with antibacterial function is one of the development directions of the coatings industry. The antibacterial coating can be prepared by adding certain suitable and stable antibacterial materials in ...
