“…To prove the superior quality of DPHA, the comparison of various reported reactive diluents such as phosphorus nitrogen with aliphatic side chain in the molecular structure [UV-curable coating system (UV-RA)], phosphorus containing phosphorous glycidyl bisphenol-A (PGBPA) and phosphorus-silicon containing Phosphorous-Silicon (PSi) on the basis of gel content and water absorption properties is shown in Table 5 and 6, respectively (Mulge et al , 2019; Naik et al , 2019).…”

Purpose The purpose of this work was to develop a new trispiperazido phosphate-based reactive diluent (diphosphate-piperazine hydroxyl acrylate [DPHA]) and used as a flame retardant with an epoxy acrylate (EA) in ultraviolet (UV)-curable wood coating. Design/methodology/approach The concentration of reactive diluent was varied from 0% to 20% in the UV-curable formulation with constant photoinitiator concentration. The effect of DPHA concentration on film properties was studied by differential scanning calorimetry and thermogravimetric analysis, gel content, water absorption and limiting oxygen index. Findings The results showed that the viscosity of the prepared formulation decreased by increasing reactive diluent (DPHA) concentration which leads to improving the coating efficiency. A high concentration of reactive diluent (DPHA) of the cured films shows good resistance against stain, mechanical and thermal properties, which results in an increased glass transition temperature (Tg) and cross-linking density of the films. Originality/value The new trispiperazido phosphate-based reactive diluent was used in wood coating formulation, which resulted in excellent flame-retardant properties with higher cross-linked density with good stain resistance. This material can provide a wide range of application for coating industries to produce a glossy finish.

“…[ 38 ] Due to overlapping with stretching vibration of COH in wood, there was no significant P═O absorption peak in plywood after flame retardant treatment. The absorption peak at 1034 cm −1 was caused by the stretching vibration of the CO bond in the wood, [ 39 ] which was caused by cellulose, hemicellulose, and lignin in the wood. In addition, the chemical composition of chitosan and cellulose in 170BF‐B was similar, and both were composed of glucopyranosyl units.…”

To improve the flame retardant performance of plywood and reduce the reagent loss and moisture absorption of the flame retardant, a bio-based supramolecular flame retardant is prepared by vacuum-pressure impregnation and high-temperature in situ polymerization in plywood. The best value of bonding strength appears at 170 °C, and the limiting oxygen index (LOI) of 170BF-B plywood is 42.3%. After hot pressing, the moisture absorption rate of the 170BF-B veneer is only 18.51%, while the loss resistance rate achieves 83.45%. Its residue at 700 °C is 91.36% higher than that of poplar veneer. In the combustion process, the peak value of heat release rate (PHRR) and heat release rate (HRR) of 170BF-B plywood are only 10.69% and 37.11% of that of untreated plywood. After combustion, an intumescent flame retardant layer exhibits a graphitization trend. In the flame retardant layer, there are not only functional groups, such as P═O, PO 4 3− , P-O-C decomposed by flame retardant but also characteristic functional groups of wood fiber, like C═O, C-H, etc. The prepolymer BF-B, which is composed of phytic acid, urea, and dicyandiamide polymerized with chitosan or lignocellulose to form a supramolecular flame retardant connected with P-O-C and P-O-N functional groups, thus improving the flame retardant and anti-loss property by in situ polymerization.

“…Coatings on the surface of wood can make up for these defects and play a role in protection and beautification [ 4 ]. In addition, wood coatings can not only stabilize the performance of wood materials, but also have the functions of anti-corrosion, flame-retardant, and fragrance retention [ 5 ]. Among many kinds of wood coatings, waterborne coatings are very popular in wood finishing because of their advantages of protecting the environment, and being pollution-resistant and fast-drying [ 6 ].…”

The fluorane thermochromic microcapsules and waterborne acrylic resin microcapsules were added into waterborne coatings at the same time to prepare intelligent waterborne coating film with dual functions of color change and self-repairing. The coating film prepared by adding 15.0% fluorane microcapsules and 5.0% waterborne acrylic resin microcapsules to the primer at the same time had better comprehensive properties. At this time, the coating film changed from yellow to colorless. The repair rate of the coating film was 58.4%. When the temperature was lower than 32 °C, waterborne acrylic resin microcapsules can improve the thermochromic performance of the coating film with fluorane microcapsules. Waterborne acrylic resin microcapsules can alleviate the color change of coating film with fluorane microcapsules. The fluorane microcapsules can improve the self-repairing performance of coating film with waterborne acrylic resin microcapsules. The results lay a theoretical and technical foundation for multifunctional coating film.
