Problems solved by technology

[0003] The current UV curing materials are various, but there are still some problems to varying degrees. The existing UV curing coatings have a large shrinkage rate after photocuring and produce shrinkage stress, resulting in brittleness of the coating film, adhesion and impact resistance. Poor, poor flexibility and low hardness of the coating film, no corrosion resistance, easy yellowing and aging, etc. These series of problems need to be continuously improved for different purposes, reduce production costs, and expand uses

Abstract

The invention discloses an ultraviolet-curable coating material with antibacterial and antioxidant effects. The ultraviolet-curable coating material is characterized by being prepared from the following raw materials in parts by weight: 40-45 parts of epoxy acrylate, 10-14 parts of polyurethane acrylate resin, 9-12 parts of 1,6-bis(acryloyloxy)hexane, 7-9 parts of methacryloyl chloride, 3-4 parts of 1-hydroxyl cyclohexyl phenyl ketone, 13-16 parts of ethoxylated triacrylate trimethylolpropane, 9-12 parts of o-methylphenyl phenyl glycidyl ether, 1-2 parts of polydimethylsiloxane, 1-2 parts of IPBC (Iodopropynylbutylcarbamate), 5-7 parts of clay and 4-5 parts of assistant. According to the coating material disclosed by the invention, IPBC is added as an antibacterial component, so that the coating material has a good antioxidant effect and an antifungal effect; the assistant is added, so that the coating material is good in leveling property, a uniform coating can be formed, and the coating material is high in curing speed and tough and has a strong adhesive force, and can be used for treating various sterile surfaces in public places.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an ultraviolet curing coating with antibacterial and anti-oxidation effects and a preparation method thereof. Background technique [0002] UV curing coatings have become a relatively mature technology, especially with the improvement of people's awareness of environmental protection, production and researchers pay more attention to the development and application of UV curing coatings. UV curing coating is a kind of green and environment-friendly coating, which fully complies with the "4E" principle. Generally, the energy consumption of UV curing is 1 / 5 of that of thermal curing, and UV curing coating contains less volatile components and less pollution. It is most attractive to researchers. And the developer's advantage is that UV curing coatings can reduce raw material consumption, which is beneficial to reduce economic costs. [0003] The current UV curing materi...
