Flame Retardant Properties

Phenolic fiber is a new fiber and has excellent flame retardant properties. In order to investigate the textile possibility of phenolic fiber and to develop protective clothing and decorative fabrics containing phenolic fiber, the mechanical properties of phenolic fiber were studied firstly, then the polyester fiber was chosen to blend with different portion of phenolic fiber to enhance the strength of the blended yarn and finally the fabrics were knitted with different blended yarns. The strength and wear resistance of different blending ratio of phenolic/polyester blended yarn, and the bursting strength, abrasion resistance and flame retardant properties of the blended fabrics were analyzed and compared. The experimental results shows that the breaking tenacity and elongation at break are low, only 1.3 cN/dtex and 9.4%, respectively, which is not suitable for 100% phenolic fiber to be processed in yarn. The strength and wear resistance of the phenolic/polyester blend yarns and their knitted fabrics increase while the contents of polyester are increased. The flame retardant of phenolic/polyester blend fabrics is improved greatly due to phenolic fiber. Therefore, it is necessary for phenolic fiber to modify its strength and extension in order to be able to get the 100% phenolic yarn and products and in order to give full play to the excellent characteristics of the phenolic fiber.

Polyurethane Prepolymer

Phenolic foams (PFs) are lightweight (<200 kg/m3), high-quality, and inexpensive thermal insulation materials whose heat and fire resistance are much better than those of foam plastics such as polyurethane and polystyrene. They are especially suitable for use as insulation in chemical, petroleum, construction, and other fields that are prone to fires. However, PFs have poor mechanical properties, poor abrasion resistance, and easy pulverization. In this paper, a polyurethane prepolymer was treated with an isocyanate, and then the isocyanate-terminated polyurethane prepolymer and poplar powder were used to prepare modified lignin-based phenolic foams (PUPFs), which improved the abrasion resistance and decreased the pulverization of the foam. The foam composites were comprehensively evaluated by characterizing their chemical structures, surface morphologies, mechanical properties, thermal conductivities, and flame-retardant properties. The pulverization ratio was reduced by 43.5%, and the thermal insulation performance and flame-retardancy (LOI) were improved. Compared with other methods to obtain lignin-based phenolic foam composites with anti-pulverization and flame-retardant properties, the hybrid reinforcement of foam composites with an isocyanate-terminated polyurethane prepolymer and poplar powder offers a novel strategy for an environmentally friendly alternative to the use of woody fibers.

New composite foams were prepared by co-foaming of Melamine-Urea-Formaldehyde (MUF) resin and wood fiber in the closed mould at 70°C. The effects of amount of wood fiber on mechanical properties, brittleness, flame-retardant, insulation and microscopic structures of wood fiber-MUF foam were investigated. Results indicated that the flame-retardant properties increased, and the brittleness and mechanical properties decreased with the increase of the amount of wood fiber in composite foams. The addition of wood fiber resulted in more uniform cell size distribution and irregular cell shape, but had little effect on insulation properties.

Flame-retardant properties of ammonium polyphosphate (APP) and its two microcapsules, APP with a shell of melamine–formaldehyde (MF) resin (MFAPP) and APP with a shell of epoxy resin (EPAPP), were studied in styrene–butadiene–styrene (SBS). The results indicate that APP after the microencapsulation leads to an increase in limiting oxygen index in SBS compared with APP. When dipentaerythritol is incorporated into the SBS composites containing the APP microcapsules, a further improvement in flame retardancy of the composites is observed. The microencapsulation does not result in much improvement of mechanical properties. Moreover, the effect of a compatibilizer (SBS grafted with maleic anhydride) on flame-retardant and mechanical properties of SBS/APP composites was investigated.

Flame Retardant Properties

Polymer materials are ubiquitous in daily life. While polymers are often convenient and helpful, their properties often obscure the fire hazards they may pose. Therefore, it is of great significance in terms of safety to study the flame retardant properties of polymers while still maintaining their optimal performance. Current literature shows that although traditional flame retardants can satisfy the requirements of polymer flame retardancy, due to increases in product requirements in industry, including requirements for durability, mechanical properties, and environmental friendliness, it is imperative to develop a new generation of flame retardants. In recent years, the preparation of modified two-dimensional nanomaterials as flame retardants has attracted wide attention in the field. Due to their unique layered structures, two-dimensional nanomaterials can generally improve the mechanical properties of polymers via uniform dispersion, and they can form effective physical barriers in a matrix to improve the thermal stability of polymers. For polymer applications in specialized fields, different two-dimensional nanomaterials have potential conductivity, high thermal conductivity, catalytic activity, and antiultraviolet abilities, which can meet the flame retardant requirements of polymers and allow their use in specific applications. In this review, the current research status of two-dimensional nanomaterials as flame retardants is discussed, as well as a mechanism of how they can be applied for reducing the flammability of polymers.

In order to understand the influence of the blended ratio of the soybean protein fibers to the properties of blended fabrics, five soybean protein fiber/modal blended fabrics are knitted and tested. By the analysis of the results, the relationship between the properties of the blended fabrics and the blended ratio of the soybean protein fibers are obtained. With the increase of the ratio of the soybean protein fibers, the tensile strength and the elongation of the blended fabrics increase and the tearing strength and bursting strength of the fabric decrease. With the increase of the ratio of soybean protein fibers, the softness increases and the bending length, abrasion resistance of the knitted fabrics decrease.
