The fire resistance property of epoxy resin is crucial for its engineering applications. In this work, a eugenol-based flame retardant containing phosphorus (P) and silicon (Si) groups (EGN-Si/P) was synthesized via the Williamson etherification subsequent hydrosilylation reaction. resulting EGN-Si/P used as bisphenol A (DGEBA). passed UL-94 V-0 rating had high limiting oxygen index (LOI) value 28% when only 0.5 wt % Si/P content introduced into hybrid system. results cone calorimetry tests...

Developing epoxy resins with superior toughness, flame retardant and hydrophobic as well dielectric properties remains a huge challenge. Herein, an additive (ETP) was prepared by grafting phosphorus-containing molecules into the skeleton of silicone resin through silicon hydrogen addition reaction. Through such design, obtained ETP imparted Bisphenol A (DGEBA) excellent flexibility, fire safety, hydrophobicity dielectrical property. When only 6 wt% introduced DGEBA system, resulting product...

High-performance and multifunctional epoxy resins are in increasing demand the booming electrical electronic fields; however, complexity high cost of process pose a huge challenge for its manufacture. Herein, two phosphorus–silicone flame retardants (DTEP DDEDP) were synthesized by grafting rigid phosphaphenanthrene structure into soft cyclic silicone resin, where whole is solvent-free, cost-effective, 100% atomic economy. The cured products containing 5 wt % DTEP DDEDP (i.e., DTEP-5...

Developing a highly efficient multifunctional epoxy adhesive is still an enormous challenge, which can rapidly cure at room temperature and has excellent low-temperature resistance performance crucial for the electrical sealing fields during severe cold seasons. Herein, diglycidyl phthalate (DP) was synthesized with phthalic anhydride (PA) epichlorohydrin (ECH) to enhance curing rate of bisphenol A ether (DGEBA) adhesive. The modified DP/DGEBA adhesives were systematically analyzed by gel...

Poly(lactic acid) (PLA) is a green but brittle thermoplastic, and its flexibility must be improved to meet the requirements of application. In this work, series waste frying oil-derived esters including ethoxylated methyl were developed then used as plasticizers for PLA. The influences ester groups on miscibility, mechanical properties, volatility resistance, biodegradation plasticized PLA systematically studied contrasted with that blended dioctyl terephthalate. Glass transition temperature...

Three epoxy resins castor oil glycidyl ether (COGE), epoxidized (ECOGE) and hydrogenated (HCOGE) have been synthesized based on through a mild epoxidation reaction. The research curing performance shows that the modified products could improve toughness of traditional remarkably. Moreover, when adding small amount into resin E‐51, mechanical properties cured were also significantly improved. Specifically, by blending ECOGE E‐51 at ratio 5%, tensile strength, elongation break, impact...

Families of bio-based hyperbranched epoxy (HBPEEs) were successfully prepared using renewable xylitol, bisphenol A and epichlorohydrin as feedstocks. The structure physical performances HBPEEs characterized by FTIR, NMR, GPC viscosity evaluation. Then, they used high efficient tougheners for diglycidyl A/diethylenetriamine (DGEBA/DETA) networks. results indicated that the incorporation into DGEBA system can significantly enhance mechanical properties solvent resistance hybrid (HBPEEs/DGEBA)....

Abstract Gemini-type imidazoline quaternary ammonium salt is a new type of environmentally friendly corrosion inhibitor has been widely used in engineering materials. However, most them are hazardous/toxic compounds derived from petroleum-based products, which did harm to environment. In this work, an Gemini-shaped (G211) was synthesized using cheap fatty acid recycled dimer industry as feedstock. The inhibition effects G211 on Q235 steel 1 M HCl solution were investigated through weight...

Developing vegetable oil-derived primary plasticizers for poly(vinyl chloride) (PVC) is still a challenge because of their insufficient compatibility. As described in this work, we report the synthesis through esterification polyethylene glycol methyl ether and dimer acid, which acid renewable material prepared via two-step reaction (1) hydrolysis fatty acids from soybean oil at 70 °C (2) subsequent Diels-Alder 250 °C. The resulting plasticizers, acid-derived esters (DA-2n, 2n = 2, 4, 6 or 8...

Paper derived from lignocellulose has great advantages over plastics as packaging material, nevertheless, the poor water- and oil-resistances of paper-derived products limited their application in high-end field. Herein, novel dimer acid-based waterborne polyurethanes (DWPUs) with different content polyester polyol (DG) were prepared used oil-resistant coating for paper substrate. The effects DG contents on oil-resistances, mechanical properties thermal stability DWPUs coated papers...

The use of vegetable oil-dervied plasticizers to enhance the flexibility polylactic acid (PLA) has received much attention due their renewability, inexpensiveness and biodegradation. However, double bonds in oil-based limit compatibility with PLA, resulting PLA-derived products reduced flexibility. Herein, we examined soybean oil-derived hydrogenated dimer acid-based polyethylene glycol methyl ether esters (HDA-2n, 2n = 2, 4, 6 or 8, referring ethoxy units) developed via direct...

A series of new environment-friendly plasticizers was synthesized from castor oil and used to plasticize nitrile rubber (NBR).
