Problems solved by technology

[0003] The method proposed in Chinese Patent 200810030170.9 "An Antibacterial UV Coating and Its Manufacturing Process" is complicated in production process, and it needs to grind the antibacterial semi-finished product first, and then mix and disperse evenly with the semi-finished coating. Unable to verify, the curing conditions are limited to UV, and other radiation curing methods such as LED are not mentioned;
[0004] The method proposed in the Chinese patent 200910008594.X "UV light-cured sterilizing coating and its preparation method" mainly involves UV glue, and does not mention coatings, and the construction operation is complicated. UV glue needs to be sprayed first, and then cured. A sterilizing coating is applied to the surface, which does not integrate antibacterial, antiviral and deodorizing functions. The curing conditions are limited to UV, and other radiation curing methods such as LEDs are not mentioned.

Abstract

The invention relates to an efficient antibacterial and antiviral two-in-one odorless radiation curable coating and a preparation method thereof. The efficient antibacterial and antiviral two-in-one odorless radiation curable coating is prepared from the following components in parts by weight: epoxy acrylate, polyester acrylate, polyurethane acrylate, a dispersing agent, an antifoaming agent, a nano-silver-loaded active agent, a filler, a leveling agent, a photoinitiator and an active diluent. According to the invention, only one antibacterial and antiviral active agent is selected to achieveefficient and lasting antibacterial and antiviral effects; the photoinitiator disclosed by the invention can reduce the odor of a coating film and achieve an odor removal effect; during construction,various curing means such as UV curing and LED curing can be adopted; the efficient antibacterial and antiviral active agent is a nano-silver active agent loaded on glass beads, can control slow release of silver ions, and has good lasting antibacterial property.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-efficiency antibacterial and antiviral two-in-one deodorizing radiation-cured coating and a preparation method thereof. Background technique [0002] Radiation-cured coatings have the advantages of efficient construction, high hardness of the paint film, and high physical and chemical properties. With the gradual maturity of radiation-cured technology, radiation-cured furniture, radiation-cured flooring and other products emerge in an endless stream, such as dining tables, cabinets, wardrobes, wooden floors, veneers etc. These products are in close contact with people's lives. In order to meet people's needs for a better life, create a healthy living environment, and prevent bacteria and viruses from infecting people, people put forward higher requirements for radiation-cured coatings. It integrates high-efficiency antibacterial, anti-virus, and deodorizing functions. [0003] The...
