“…Nano-fillers have a large specific surface area/volume ratio, so the interaction between polymer and nano-fillers can be enhanced even with relatively low loading. This makes nano-fillers a better choice because of their low cost and ensures that the original properties of the polymer are not affected by overloading [ 92 , 93 , 94 , 95 , 96 , 97 ].…”

Against the background of people’s increasing awareness of personal safety and property safety, the flame retardancy (FR) of materials has increasingly become the focus of attention in the field of construction engineering. A variety of materials have been developed in research and production in this field. Polymers have many advantages, such as their light weight, low water absorption, high flexibility, good chemical corrosion resistance, high specific strength, high specific modulus and low thermal conductivity, and are often applied to the field of construction engineering. However, the FR of unmodified polymer is not ideal, and new methods to make it more flame retardant are needed to enhance the FR. This article primarily introduces the flame-retardant mechanism of fire retardancy. It summarizes the preparation of polymer flame-retardant materials by adding different flame-retardant agents, and the application and research progress related to polymer flame-retardant materials in construction engineering.

“…At higher temperatures, the plasticizer (DOP) degrades with thermal disintegration of the conjugated polyene molecules at 409°C. [ 35 ] A similar behavior of thermal decomposition at relatively lower temperatures is noticed upon loading MO onto PVC. This may be attributed to the volatile content for MO.…”

Poly(vinyl chloride) (PVC) was loaded with various contents of Moringa oleifera (MO) leaves extract. The changes in the structure arising after loading MO into the polymeric matrix were monitored. In addition, their rheological and mechanical properties were investigated. Some thermal analyses techniques were performed to demonstrate any change in the thermal stability of PVC before and after adding MO. PVC/MO exhibited noticeable antibacterial efficiency when evaluated against Gram-positive and Gramnegative bacteria. A favorable antibacterial efficiency of PVC/MO boosted with increasing of MO content from 5% to 25% by weight when introduced into PVC. The photostability of PVC enriched with MO was investigated. The change in the rate of dehydrochlorination for PVC was detected. It was indicated with liberating HCl from the polymeric matrix.

“…Figure 8 shows the tensile stress–strain curves of PVC composites, and the related results are displayed in Table S3. Compared with the neat PVC, the tensile strength of the PVC/CMF‐2.5, PVC/SnO 2 ‐2.5, and PVC/CMF‐SnO 2 ‐2.5 were all slightly reduced due to the large grain size of flame retardants, which could not be compatible with the polymer matrix very well 41,42 . Besides, the elongation values at the break of the other three samples were similar to those of the neat PVC, which meant that the addition of a small amount of CMF, SnO 2 , and CMF‐SnO 2 did not damage the flexibility of the PVC composite so much.…”

Melamine‐formaldehyde (MF) foam has wide applications due to good flame retardancy, excellent sound absorption, and high thermal stability. However, the recycling of MF foam wastes remains a challenge due to its thermosetting nature. Here, we demonstrate a new strategy for discarded foams as solid adsorbents for removing tin ions in simulated tin‐containing wastewater. Results showed that the removal rate of tin in simulated wastewater is as high as 99.996%. Moreover, after simple calcination, as‐obtained products can be used as high‐efficiency flame retardants for flexible poly(vinyl chloride) (PVC), reducing the peak of heat release rate and total smoke production of PVC by 51.8% and 45.8%, respectively, under the condition of 2.5 wt.% addition. In short, this strategy successfully converted MF foam and tin wastewater to valuable flame retardants, opening the way for the environmentally friendly recycling of MF waste and the simultaneous treatment of tin‐containing wastewater.
