“…Boron compounds belong to another type of inorganic additives with FR [ 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ]. Of the boron compounds, zinc borate (ZB), such as 2ZnO·3B 2 O 3 ·3.5H 2 O, is the most commonly used.…”

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.

“…Moreover, synthetically prepared materials have the advantage of requiring a low add-on percentage to imbue functionalities into textiles or other substrates, which is even more advantageous when the materials are converted to nano-form (Sharma et al 2016 , 2018 ; Chawla et al 2017 ; Durrani et al 2020 ; Rajpoot et al 2021 ; Ali and Sharma 2022 ). However, in many cases, these are proven to be health hazardous or environmentally not a benign solution.…”

Vanillin is an active ingredient found in the crop ‘vanilla’ and is traditionally extracted from the ‘vanilla pod’. Vanillin intrinsically is not a suitable candidate for imparting durable functional features into textile substate due to its smaller chemical structure which leads to leaching of the same during washing operation. To enlarge the structure, in the present study, vanillin has been converted into 4-(benzylamino) methyl))-2-methoxyphenol vanillin derivative (reduced Schiff base) with considerable amount of yield by using a simple one-step process and the synthesized product has been characterized by 1H, C13 NMR, FTIR, and Raman analysis. Thereafter, the reduced Schiff base of vanillin (RSB) has been integrated on cotton as well as polyethylene terephthalate (PET) fabric using high temperature high pressure (HT-HP) technique for imparting multiple functionalities. FESEM EDX analysis has confirmed the integration of RSB on both the fabrics by revealing uniform presence of the nitrogen (of the synthesized derivative) on the treated textile materials. Both types of functionalized textiles have demonstrated appealing color shades with an excellent antimicrobial activity of about 90% against Escherichia coli ( E. coli ) bacteria. The treated fabrics could cater pleasing fragrance and exhibit 90% antioxidant properties. Moreover, enlarged vanillin derivative in the form of RSB can retain its properties in the fabrics even after repeated machine launderings. RSB-treated cotton fabric has shown ultra-violet protection factor (UPF) of 38 which drops to 24 after washing whereas in case of PET treated fabric, the observed UPF values are 265 and 164 before and after washing, respectively. The RSB treatment has been found to be cytotoxically secure and biocompatible as tested on the PET fabric. Other required properties of the treated fabrics such as water absorbency, flexibility, etc. have also been found to be intact. Thus, the presented study reveals a new class of safe material that can be derived from eco-friendly vanillin and has the potential to replace hazardous chemicals that are currently used in textile chemical processing industries.

Nano particles of zinc borate were obtained by homogeneous precipitation method which is based on dissolving zinc borate in ammonia and precipitating it as nano particles by slow evaporation of ammonia. The synthesized zinc borates were characterized by advanced analytical techniques. Zinc borate nano particles were used as a lubricant additive to spindle oil having Span 60 dispersant. The particles were well dispersed in spindle oil as shown by optical microscopy of the oils. Four ball tests of the lubricants indicated zinc borate lowered (61.8%) the wear scar diameter significantly. The hardness of wear surfaces of test balls was reduced from 688 HV to 618 HV and presence of zinc borate particles embedded on the surface indicated a flexible skin was formed. Therefore the pressure was decreased due to increase of the contact area of the balls. The surface roughness was also decreased from 35.63 nm to 27.60 nm by the addition of zinc borate to spindle oil having Span 60. Zinc borate prepared by homogeneous precipitation technique lowered the wear of the surfaces that rub to each other.
