Abstract

A solvent-free UV resin and application thereof belong to the technical field of environment-friendly paints. The solvent-free UV resin is composed of, by weight percentage, 20-40% low-viscosity oligomer, 10-20% of bifunctional active diluent, 10-20% of trifunctional active diluent, 20-40% of UV curing hyperbranched polyfunctional monomer, 0.1-0.8% of flatting agent and 2-10% of photoinitiator. The solvent-free UV resin can solve the problem VOC (volatile organic compounds) led by toxic organic solvent in UV curing paints.

Description

technical field

[0001] The invention relates to a technology in the field of environmentally friendly coatings, in particular to a solvent-free UV resin and its application. Background technique

[0002] In principle, UV light curing technology can produce green products that meet the requirements of "5E (Energy Saving, Economical, Efficient, Environmental Friendly, and Enabling wide applicability)". However, in practice, due to the low viscosity requirements of the construction process and people's pursuit of low cost, UV light curing products often contain a large amount of organic solvents.

[0003] As we all know, a large amount of organic solvents (VOC) volatilize during the production and construction of solvent-based coatings, and VOC is one of the culprits of air pollution. Flammable, explosive and toxic organic solvents also pose serious safety hazards and harm to human health. With the improvement of people's living standards and the enhancement of environmental ...
