Abstract: The sustainable development of the paint and varnish industry is a prerequisite for action to minimize the negative environmental impact of paint products. They consist not only in reducing the emission of harmful VOC substances into the atmosphere but also in modifying the composition of the paint material in order to improve the properties of the coatings and at the same time reduce the amount of waste. Selection of the appropriate composition of the water-borne composition is still a problem to be solved. T… Show more

To solve the problem of bubble retention leading to a decrease in the performance of waterborne resin coatings during thermal curing, a rapid thermal curing coating based on an aqueous epoxy-modified acrylic resin containing an amino resin cross linker was synthesized through solution copolymerization. Using a synchronous thermal analyzer, the mass loss and heat flow during the thermal curing process of the coating was measured. In addition, an in situ thermal curing visualization system was used to observe the curing behavior at the easy-open end notches under different heating rates. The results indicated that the curing process is divided into an initial rapid heating stage and a subsequent slower heating stage by the boiling point of water, with a critical temperature range of 126-150°C. The visualization experiments showed that when the temperature reached 100°C, the water quickly evaporated to form bubbles. Increasing the heating rate before this temperature caused the bubbles to rapidly escape. Therefore, an optimal heating profile with a rapid initial heating rate of 3.13°C/s, followed by a slower heating rate of 0.52°C/s in the next stage, is proposed. This discovery is of great significance for optimizing the thermal curing process of waterborne coatings on metal substrates, including those used for easy-open ends.

The aim of the study was to identify limiting factors for reusing wood through the recycling of window frames by conducting research under fully controlled conditions. The research involved manufacturing new window frames, seasoning them, and then shredding them into wood particles to prepare a three-layer particleboard. The proportion of wood particles in recycling was 0, 5, 10, 25, 50, and 100 parts by weight of the manufactured particleboard. Mechanical property tests were conducted: modulus of elasticity (MOE) and modulus of rupture (MOR), internal bond (IB), screw withdrawal resistance (SWR), and physical properties: density profile (DP), thickness swelling (TS) after water immersion, water absorption (WA), as well as formaldehyde emission and total volatile organic compound (TVOCs) tests. The research indicates a significant potential for utilizing wood from this sector of the wood industry, particularly considering variants with a higher proportion of recycled wood. MOR and MOE results are most promising for variants above 50 parts by weight of recycled wood. Based on the results obtained, it is clear that the production process should be improved or the raw material modified to enhance the internal bonding of particleboard, as these results were the weakest. Thus, recycled wood from window joinery has the potential to be reincarnated as particleboard, which continues to be widely used in their production.

View full text Add to dashboard Cite

Intumescent fire-retardant coatings, which feature thinner layers and good decorative effects while significantly reducing heat transfer and air dispersion capabilities, are highly attractive for fire safety applications due to their effective prevention of material combustion and protection of materials. Particularly, the worldwide demand for improved environmental protection requirements has given rise to the production of waterborne intumescent fire-retardant polymer composite coatings, which are comparable to or provide more advantages than solvent-based intumescent fire-retardant polymer composite coatings in terms of low cost, reduced odor, and minimal environmental and health hazards. However, there is still a lack of a comprehensive and in-depth overview of waterborne intumescent fire-retardant polymer composite coatings. This review aims to systematically and comprehensively discuss the composition, the flame retardant and heat insulation mechanisms, and the practical applications of waterborne intumescent fire-retardant polymer composite coatings. Finally, some key challenges associated with waterborne intumescent fire-retardant polymer composite coatings are highlighted, following which future perspectives and opportunities are proposed.
