Antibacterial flame-retardant ultraviolet-curable coating and preparation method thereof

Abstract

The invention discloses an antibacterial flame-retardant ultraviolet-curable coating. The antibacterial flame-retardant ultraviolet-curable coating is prepared from the following raw materials in parts by weight: 33-36 parts of urethane acrylate, 19-22 parts of polyester acrylate, 12-14 parts of polyethylene glycol acrylate, 6-8 parts of glycidyl acrylate, 1-2 parts of turpentine, 4-5 parts of 2-methyl-2-hydroxy-1-phenylacetone, 5-8 parts of trimethylolpropane triacrylate, 4-7 parts of tripropylene glycol acrylate, 3-5 parts of butanone, 1-2 parts of polyacrylate, 4-6 parts of zinc oxide, 2-3 parts of talcum powder, 1-2 parts of IPBC (Iodo Propynyl Butyl Carbamate) and 4-5 parts of auxiliaries. Due to the added IPBC, the antibacterial flame-retardant ultraviolet-curable coating is safe and non-toxic, and has excellent antifungal and antioxidation effects; due to the added zinc oxide, the antibacterial flame-retardant ultraviolet-curable coating has closed effect in addition to flame retardant and antibacterial effects; furthermore, due to the added auxiliaries, the antibacterial flame-retardant ultraviolet-curable coating is good in leveling property, and an even coating coating can be formed, and the coating layer is high in curing speed, hard, wearproof, flexible and high in adhesion.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an antibacterial and flame-retardant ultraviolet light curing coating 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 materials ar...

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
