具有荧光增白作用的新型返黄抑制剂的合成及性能
Synthesis and properties of new yellowing inhibitor with fluorescent whitening
摘要
Abstract
With cyanuric chloride as the crosslinking monomer and 4,4 -diamino stilbene-2, 2 -disulfomc acid (DSD acid) as raw material, a new yellowing inhibitor for high-yield pulp was synthesized through joining the free radicals capturer 4-amion-2,2 ,6,6 -tetramentylniperidine (4-TEMP) and triazine-stilbene fluorescent brighteners in the same molecule by nucleophilic substitutions of three chlorine atoms of cyanuric chloride with amino compounds. The new product had the function of fluorescent whitening and capturing free radicals. Its structure was characterized by FT-IR and 1H NMR, and the physical properties were examined by UV-Vis and photoluminescence (PL) spectra. Besides, the effect of anti-yellowing was evaluated as the surface sizing agent on a hand-sheet of chemi-mechanical pulp by using the ultraviolet aging apparatus. The results showed that the best dosage of the new yellowing inhibitor was 0. 8% and the inhibitor could be recommended as an applicable yellowing inhibitor for lignin-content paper products, besides the brightness abilities of chemi-mechanical pulp hand-sheets were increased more by application of the new yellowing inhibitor as surface sizing agent than those by application of fluorescent brighteners and free radicals capturer alone respectively and declining brightness of hand-sheets treated by the new yellowing inhibitor was 3. 38%ISO and 6. 49%ISO, less than hand-sheets treated by application of fluorescent brighteners and free radicals capturer alone respectively after 48 h UV accelerated irradiation.关键词
