Problems solved by technology

However, the UVLED light source is a single-wavelength light source, and the emission peak width is narrow (generally the main emission wavelength is ±10nm), which is very different from the continuous emission spectrum of the traditional mercury lamp. Therefore, most of the existing light-curing floor coating systems The absorption ability of UVLED light source is very poor, and the coating film is often not cured or cured incompletely, resulting in insufficient hardness, abrasion resistance, adhesion, solvent resistance and other properties of the coating after photo-curing treatment, and it is difficult to exert the expected effect of the coating

Abstract

The invention discloses an UVLED light curing composition used in a floor coating and application thereof, the composition comprises a compound containing a (methyl acrylate group, an epoxy-group-containing compound, a diluent, a cationic photoinitiator, and optionally, a free radical photoinitiator and sensitizer, and the UVLED light curing composition has excellent response to an UVLED light source in the wavelength range of 200 to 500 nm, and has the advantages of fast curing speed, excellent coating performance, zero VOC emission, and the like. Layer hardness, wear resistance, adhesion, water resistance and chemical resistance of the UVLED light curing composition after curing can meet the performance requirements of a floor coating material.

Description

technical field [0001] The invention belongs to the technical field of photocuring applications, and in particular relates to a UVLED photocuring composition and its application in floor coatings. Background technique [0002] Floor coatings are an important branch of coatings. They provide clean, beautiful, anti-corrosion and wear-resistant solutions for the surfaces of concrete, stone, wood and other ground substrates. They are indispensable protection measures for most modern industrial plants. Compared with traditional floor coatings, UV-curable floor coatings have obvious advantages in terms of VOC control (no or low solvent emissions) and curing speed. For example, DSM's Instant Floor Coatings, as a commercially available UV-curable floor coating, has the characteristics of instant drying, no odor, and easy cleaning. [0003] With the improvement of people's awareness of environmental protection, researchers and the market pay more attention to the development and a...
