“…Cellulose paper is a widely used environmentally friendly and renewable “green” material with the advantages of low cost, lightweight and biodegradability 1–3 . However, natural cellulose paper is very easy to burn, which often brings serious hidden dangers and threats to personal safety and properties, so its flame‐retardant modification is particularly important 4–8 . One of the currently implemented methods for effective flame retardancy paper is the cellulose fiber flame retardant modification method 9–13 .…”

A simple, environmentally friendly and efficient montmorillonite (MMT)‐metal ion (Me: Mg2+, Ca2+, Fe3+ and Zn2+)‐carboxymethyl cellulose (CMC) organic–inorganic hybrid film is successfully applied to flame retardant cellulose paper through layer‐by‐layer self‐assembly (LbL) technology. Using SEM, TGA, XPS, air permeability test and horizontal flammability test to characterize its surface morphology, thermal stability, air permeability and flame retardancy. The results show that MMT‐Me‐CMC system can endow cellulose paper with high flame retardancy properties, and different metal ions have different contributions to the flame retardancy. MMT with multi‐layer structure and high specific surface area is beneficial to reduce the air permeability of paper, thereby effectively reducing the flammability of flammable pyrolysis gas and the transfer of heat. The XPS analysis shows that the Zn2+ flame retardant system promotes the formation of graphitized char in the condensed phase. Meanwhile, the possible flame‐retardant mechanism of the system is clarified. Zn2+ replaces Al3+ in MMT, thus increasing the active acidic catalytic sites on MMT. This promotes the carbonization of degradation products and forms graphitized clay‐rich char. This work provides a simple and efficient LbL preparation strategy and provides a reference for the catalytic role of metal ions in the flame retardancy of cellulose paper.

“…Its unique structure and composition make 4A have good thermal stability, absorptivity, ion exchangeability and catalytic property. Recently, various types of molecular sieves have been used alone as flame retardants to achieve a certain flame-retardant effect, or used as synergists to achieve a good synergistic flame-retardant effect [ 30 , 31 , 32 , 33 ]. Thus, 4A could be a promising candidate as a flame-retardant synergist in PP flame retardancy.…”

In this study, a ternary hydrogen (H)-bonded complex intumescent flame retardant (TH-IFR) of melamine (ME) · phosphoric acid (PA)…pentaerythritol (PER) was synthesized through hydrothermal reaction. The combination of the synthesized TH-IFR with 4A molecular sieve as the synergist was used for the first time to improve the flame retardancy of polypropylene (PP). The involved structure, morphology, flame retardancy, flame-retarding mechanism and mechanical properties of the prepared PP composites were systematically investigated. The results show that incorporation of 1 wt% synergist 4A shows the optimum synergistic effect, and the flame retardancy and mechanical properties of the flame-retarded (FR) PP composites are significantly improved. Incorporation of 4A could change the pyrolysis process of the entire system and promote the char-forming chemical interaction, thereby further enhancing the flame retardancy of FR PP composite. The synergistically flame-retarding mechanism of 4A is explained by the significantly improved quality and quantity of the solid-phase char layer, which is formed through generation of SiO2 and Al2O3 substances, and also participation of PP macromolecular chains in the final char layer formation during burning. Furthermore, the improved dispersion and compatibility of TH-IFR in the composite is largely beneficial to the improvement of flame retardancy and mechanical properties.

“…Corrugated cardboard is known for its utility as a building material [25,26], and some studies have suggested the potential of hydrophobic treatment to avoid moisture absorption and further expand its versatility [27,28]. Moreover, it may act as a flame retardant, improving building safety [29].…”

An Experimental Study on the Performance of Corrugated Cardboard as a Sustainable Sound-Absorbing and Insulating Material

2021

The continuing development of industrialization and increasing population density has led to the emergence of noise as an increasingly common problem, requiring various types of sound absorption and insulation methods to address it. Meanwhile, the recycling of resources to ensure a sustainable future for the planet and mankind is also required. Therefore, this study investigates the potential of corrugated cardboard as a resource for noise reduction. The sound absorption and insulation performance of non-perforated corrugated cardboard (NPCC) were measured, and modified corrugated boards were fabricated by drilling holes either through the surface of the corrugated board alone or through the corrugated board in its entirety. The sound-absorption/insulation performance both of perforated corrugated cardboard (PCC) and perforated corrugated cardboard with multi-frequency resonators (PCCM) were measured using the transfer function method and the transmission matrix method. To determine the effectiveness of NPCC, PCC, and PCCM in noise reduction, the sound pressure level was analyzed by applying it to a home blender. The results showed PCCM’s sound absorption and insulation performance to be excellent. On the basis of these findings, we propose the use of PMMC as an eco-friendly noise-reduction material.
