UV1130 UV Absorber Used for the Modification of Water-Based Polyurethane Coatings

Guo, Hui, et al. Coatings, 2023, 13(4), 687.

A water-based polyurethane (WPU) coating was modified with boric acid/borax anti-mildew additives and UV absorbers to improve the performance of bamboo materials for outdoor exposure. The study compared the UV absorption modification effects of three UV absorbers, including UV1130, nano-TiO2, and nano-SiO2, on water-based polyurethane coatings. The results show that all three UV absorbers have anti-mildew effects, among which UV1130 has better performance.
Preparation of coatings modified with UV1130
· Firstly, select boric acid/borax with excellent antibacterial ability and flame retardant properties as an anti-mildew additive, and add it to the WPU coating in three different ratios: boric acid/borax:WPU = 1:1, 1:1.5 and 1:2.
· After determining the appropriate ratio of boric acid/borax and WPU, add different mass fractions (1.0%, 2.0%, 3.0%) of UV1130, nano-SiO2, and nano-TiO2 ultraviolet absorbers to the anti-mildew modified WPU coatings.
· The above modified WPU coatings were coated on the surface of laminated bamboo to prepare samples for subsequent various performance tests.

Benzotriazole UV1130 Used for UV Protection Treatment of Fibers

Liu, Yuxi, et al. Journal of Adhesion Science and Technology, 2014, 28(18). 1773-1782.

In order to avoid the aging problem of Vectran fibers caused by ultraviolet radiation, TiO2 nanosol, benzotriazole UV-1130, triazine Tinuvin 477 and hindered amine Tinuvin 123 were used to jointly develop a new organic/inorganic hybrid coating. In this hybrid coating, UV-1130 particularly enhances the UV protection capability of the coating due to its strong UV absorption ability.
Sol-gel synthesis of hybrid TiO2/organic UV absorbers
· TiO2 sol was first prepared using butyl titanate, absolute ethanol, hydrochloric acid, deionized water, and glacial acetic acid as raw materials.
· The prepared TiO2 sol was left to stand for a certain period of time, and then different UV absorbers (UV-1130, Tinuvin 477 and Tinuvin 123) were added. The mixtures were stirred and dispersed to obtain TiO2/organic UV absorbers hybrid solutions.
· The Vectran fiber was dipped in TiO2 /organic UV absorbers hybrid solutions for surface treatment. The UV protection properties of the hybrid coatings were investigated by exposing the specimens to UV radiation for 24, 96, and 336 h.
