AI Technical Summary

Problems solved by technology

The yellowing of UV varnish is the oxidation, degradation, and rearrangement of varnish components, resulting in carbon-carbon double bonds or quinone structures, which turn the coating color yellow and affect the appearance of light-colored plastic products, especially as the yellowing intensifies , the performance of the coating will continue to deteriorate, even peel off, lose its protective effect, and greatly reduce the wear and scratch resistance

Embodiment 1

[0009] 1000 grams of aliphatic polyurethane hexaacrylate, 600 grams of butyl acrylate, 300 grams of dipropylene glycol diacrylate, 80 grams of 2-hydroxy-2-methyl-1-phenylacetone, 20 grams of 1-hydroxycyclohexyl benzophenone grams, added to the dispersing kettle, and stirred evenly.

[0010] After corresponding surface treatment, the plastic hose is coated with the UV varnish prepared in this example, and cured under a UV lamp. The UV aging performance test of the obtained UV varnish coating reaches the first grade of yellowing resistance, and is flexible and scratch-resistant. Good abrasiveness. After twelve months in the natural environment, the coating is still colorless and transparent, and no obvious changes have been seen.

Embodiment 2

[0012] Aliphatic polyurethane hexaacrylate 1200 grams, butyl acrylate 500 grams, dipropylene glycol diacrylate 200 grams, 2-hydroxy-2-methyl-1-phenylacetone 60 grams, 1-hydroxycyclohexylbenzophenone 40 grams, added to the dispersing kettle, and stirred evenly.

Abstract

The invention belongs to the technical field of anti-wear and anti-scratching processing of the surface of a plastic product and particularly relates to an anti-yellowing UV (ultraviolet) varnish. The anti-yellowing UV varnish is characterized in that the anti-yellowing UV varnish comprises the following components in percentage by weight: 50-80% of aliphatic polyurethane hex-acrylate, 15-30% of butyl acrylate, 0-15% of dipropylene glycol diacrylate, 1-4% of 2-hydroxyl-2-methyl-1-phenylacetone and 1-4% of 1-hydroxycyclohexyl phenyl ketone. The anti-yellowing UV varnish has good anti-yellowing performance and coating flexibility and is particularly suitable for use in anti-wear and anti-scratching processing of a plastic hose.

Description

technical field [0001] The invention belongs to the technical field of anti-wear and scratch-resistant processing of the surface of plastic products, and in particular relates to an anti-yellowing UV varnish. Background technique [0002] UV varnish is a high-resolution material that can be cured into a film under ultraviolet light. The coating and curing equipment is simple and the production efficiency is high. It is an environmentally friendly and energy-saving coating. It is often used for anti-wear and scratch-resistant processing of plastic products. Its main components are: photosensitive resin, reactive diluent monomer, photoinitiator and other additives. The yellowing of UV varnish is the oxidation, degradation, and rearrangement of varnish components, resulting in carbon-carbon double bonds or quinone structures, which turn the coating color yellow and affect the appearance of light-colored plastic products, especially as the yellowing intensifies , the performanc...
