Safety environment-friendly wear-resistant ultraviolet curing coating and preparation method thereof

Abstract

The invention discloses a safety environment-friendly wear-resistant ultraviolet curing coating which is characterized by being prepared from the following active ingredients in parts by weight: 50-53 parts of polyester acrylate, 10-13 parts of 1,6-hexamethylene diacrylate, 7-9 parts of methoxy polyethylene glycol methacrylate, 3-4 parts of photoinitiator, 13-15 parts of dipentaerythritol hexaacrylate, 9-12 parts of butyl acetate, 1-2 parts of polymethylphenyl silicone, 1-2 parts of antioxidant, 7-9 parts of nano bentonite, 2-3 parts of nanoscale bamboo charcoal, 1-2 parts of IPBC (iodopropynyl butylcarbamate), and 4-5 parts of auxiliaries. Due to the added nano bentonite and nanoscale bamboo charcoal, the dispersion property is good and the mobility is enhanced, and the nanoscale bamboo charcoal powder has excellent electromagnetic shielding action, can release negative ions and far infrared rays, thus being safe and harmless to a human body; due to addition of auxiliaries, the leveling property is good, the coated film is good in adhesion force, large in hardness, wear-resistant and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a safe, environment-friendly and wear-resistant 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 m...

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
