Ningbo bio-based thermooenstic resin research has been a series of progress

With the increasingly extensive and in-depth research on bio-based polymer materials, bio-based thermosolytic resins as an important category of bio-based polymer materials have been gradually received and paid attention to. However, how to realize its high performance, function and application through the selection, molecular structure design and regulation of bio-based platform compounds has always been a difficult problem. The research team of bio-based polymer materials of Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences has taken the lead in the layout and research direction of bio-based thermosolytic resins in China, and in recent years has made a series of progress in the research of high-performance bio-based epoxy resins based on pine acid, vegetable oil, eryconic acid, soybean protein, etc.
, also known as medehydine, is considered a bio-based platform compound with broad application prospects due to its special chemical structure, low price and mature biofermentation production process. Based on it, the research team of bio-based polymer materials of Ningbo Materials successfully obtained the glass transition temperature, stretch strength, bending strength and modality of 130.4 degrees C, 87.5MPa and 152, respectively, by adjusting its cyclooxidation degree and active function group density. .4MPa and 3400Mpa epoxy resin EIA, through the double curing of epoxy opening ring and double-bond polymerization, achieve its comprehensive performance of controlled and adjustable (GreenChemistry, 2013, 15, 245); Direct cyclooxidation, the synthesis of three-degree energy bio-based fat epoxy resin TEA, while achieving high epoxy value (1.16), very low viscosity (0.92Pas, 25 degrees C) and high thermodynamic properties (Tg-135) C, mod 3600Mpa), the resin exhibits better thermodynamic and processing properties than ordinary petroleum-based epoxy resins (Chemsuschem, 2013, 7,555); The hydrophosphate-9-oxygen hybrid-10-phosphorus hexafillyceride-10-oxide (DOPO) is branched to the epoxy resin of icomaic acid and obtains a phosphorus epoxy resin EADI with self-flame retardant properties (UL-94V0 grade), which can be used alone in self-retardant resins or reactive epoxy retardants (Science China, chemistry, 2014, 57,379).
Recently, they polymerized chloric acid with binary alcohols of different lengths, and by regulating the density and molecular chain polarity of co-polyester's lively dual bonds, they developed a series of bio-based water-based UV-cured resins based on icomic acid, which showed good adhesion, solvent resistance, hardness (Prog.Org.Coat., 2015, 78,49). By adding propylene triol to the above-mentioned co-polyester to its degree of branching, they are re-matched with soybean oil derivatives (AESO), and a series of 100% solid content, all-biological base, UV-curable new resins are obtained. They have been cured with excellent pencil hardness, adhesion, water resistance, solvent resistance and thermodynamic properties, and are expected to develop into a new class of UV curing coatings with high overall performance (GreenChemistry, 2015, DOI:10.1039/cgc02057j). The series of resins is intended to be piloted and amplified.
