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 a special UV (Ultraviolet) curing antibacterial coating for plastics. The special UV curing antibacterial coating for plastics is characterized by being prepared from the following active ingredients in parts by weight: 50-55 parts of epoxy acrylate, 9-12 parts of polyethyleneglycol diacrylate, 7-10 parts of hydroxypropyl acrylate, 4-6 parts of glycidyl acrylate, 3-4 parts of 2-methyl-2-(4-morpholinyl)-1-[4-(methylthio)phenyl]-1-acetone, 12-15 parts of methacrylate laurate, 9-12 parts of ethyl acetate, 1-2 parts of polydimethyl siloxane, 1-2 parts of silane coupling agent KH550, 6-8 parts of nanometer wollastonite, 3-4 parts of lithopone, 1-2 parts of IPBC (iodopropynyl butylcarbamate), and 4-5 parts of auxiliaries. Due to added IPBC antibacterial substances, the special UV curing antibacterial coating has the effects of oxidation resistance and mildew repression; due to the auxiliaries, the coating is good in leveling property, good in flexibility, hardness, adhesion force, wear resistance and scratch resistance, energy-saving and environment-friendly, and high in production efficiency and application to plastic surfaces.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a special UV curing antibacterial paint for plastics 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 are various, but ther...
