Formaldehyde-free flame-retardant solid wood composite floor and modified lignin-based flame-retardant adhesive
The invention provides a formaldehyde-free flame-retardant solid wood composite floor and a modified lignin-based flame-retardant adhesive, the flame-retardant adhesive provided by the invention is composed of 20-30 parts by weight of ethanol lignin, 20-30 parts by weight of hydroxide, 10-20 parts by weight of phytate, 30-60 parts by weight of a cross-linking agent, 30-50 parts by weight of high-temperature soybean meal powder and 0.1-0.2 part by weight of a tackifier, and the invention also provides a preparation method of the formaldehyde-free flame-retardant solid wood composite floor. The preparation method comprises the following steps: grafting amino-rich hydroxide and phytate onto ethanol lignin to obtain hydroxide/phytate ethanol lignin, mixing the obtained hydroxide/phytate ethanol lignin with a cross-linking agent and high-temperature soybean meal powder, adding a tackifier, and mechanically stirring to obtain the modified lignin-based flame-retardant adhesive. The flame-retardant adhesive provided by the invention is free of formaldehyde addition, excellent in flame retardance, good in coating performance, good in water resistance and huge in application potential.
本发明提供了一种无醛阻燃型实木复合地板及改性木质素基阻燃型胶粘剂，本发明提供的阻燃胶粘剂由20～30重量份乙醇木质素、20～30重量份氢氧化物、10～20重量份植酸盐、30～60重量份交联剂、30～50重量份高温豆粕粉、0.1～0.2重量份增粘剂组成，同时本发明提供其制备方法。首先将富含胺基的氢氧化物和植酸盐枝接到乙醇木质素上得到氢氧化物/植酸盐乙醇木质素，其次将获得的氢氧化物/植酸盐乙醇木质素与交联剂、高温豆粕粉混合，最后加入增粘剂，机械搅拌制备得到改性木质素基阻燃胶粘剂。本发明提供的阻燃胶粘剂无甲醛添加，阻燃性能优异，涂布性能佳，胶粘剂耐水性能好应用潜能巨大。
