“…Polymer materials have contributed significantly to the development of modern society, due to their excellent properties, including high workability, low price, and good chemical resistance [ 1 , 2 , 3 , 4 , 5 , 6 ]. However, the flammability of most polymer materials greatly limits their wide range of applications [ 7 , 8 , 9 , 10 ]. One proposed solution to this problem is the development of flame retardants [ 11 , 12 , 13 , 14 ], which could restrain the ignition and fire-spreading of polymer materials, specifically decreasing heat release and smoke production.…”

To meet the growing needs of public safety and sustainable development, it is highly desirable to develop flame-retardant polymer materials using a facile and low-cost method. Although conventional solution chemical synthesis has proven to be an efficient way of developing flame retardants, it often requires organic solvents and a complicated separation process. In this review, we summarize the progress made in utilizing simple ball milling (an important type of mechanochemical approach) to fabricate flame retardants and flame-retardant polymer composites. To elaborate, we first present a basic introduction to ball milling, and its crushing, exfoliating, modifying, and reacting actions, as used in the development of high-performance flame retardants. Then, we report the mixing action of ball milling, as used in the preparation of flame-retardant polymer composites, especially in the formation of multifunctional segregated structures. Hopefully, this review will provide a reference for the study of developing flame-retardant polymer materials in a facile and feasible way.

“…The largest share of binder production, representing 65 % of the market, is used in the wood binder industry for the production of wood composites [3] . In addition to isocyanate and epoxy resins, a large proportion of industrially produced binders consist of formaldehyde resins, the most important of which are urea‐formaldehyde (UF), phenol‐formaldehyde (PF), and melamine‐formaldehyde (MF) resins [4] . A disadvantage is that they are non‐renewable, as their raw materials are based on fossil sources, which is why it is becoming increasingly important to switch from fossil to renewable feedstocks due to the high impact of CO 2 emissions on climate change [5] …”

Novel Synthetic Strategy for the Production of Fully Bio‐Based Binders Using 2,5‐Diformylfuran

In this work, resol based binders were prepared with lignin, resorcinol and the bio-based aldehydic platform chemicals 5hydroxymethylfurfural (HMF) and 2,5-diformylfuran (DFF). In preliminary studies, the solubility and stability of DFF in aqueousalkaline conditions was investigated. Various binders were prepared to investigate the influence of the HMF-DFF ratio and the influence of the aldehyde concentration on the molar mass, rheological properties and curing characteristics of the final binders. It is shown that significantly higher molecular weights and viscosities are obtained by using DFF instead of HMF. The properties of the final binder could also be affected by the precise choice of DFF concentration, as this resulted in higher levels of crosslinking. This work offers a novel type of fully bio-based binder that consists of non-toxic components and is therefore less hazardous than some conventional binders.

This paper deals with investigating the feasibility of using waste plum pits in the production of composite particleboard materials and the improvement of their mechanical and physical properties. Biodegradability, flammability and water absorption are the primary disadvantages of wood-based composites, which reduce their service life. In this experimental study, waste colemanite was used to decrease the known flammability of wood composites. Phenol formaldehyde (PF) was used to increase the water resistance and prevent biodegradability of the prepared materials, and hemp fiber was added to increase their mechanical strength. Thus, the objective was to avoid the disadvantages of wood-based materials. Based on the results of the flexural strength test, the optimum polymer composite material production parameters were determined to be as follows: 0.50 filler/binder ratio, 56 kg/cm2 moulding pressure and 0.75 hemp fiber ratio. According to the results of the experiments, the use of waste colemanite in the production of composite materials improves their non-flammability, while decreasing flexural and screw withdrawal strengths. It was determined that waste plum pits could be used to substitute for wood chips, as an alternative filler material in the production of composite materials. As a result, eco-friendly polymer composite materials were produced from waste plum pits, hemp fiber, and waste colemanite. The obtained composite materials are compliant with applicable standards and are suitable for application as building materials for use in both interior and exterior space.
