Synthesis, Characterization and Composites from Resorcinol-urea-formaldehyde-casein Resin

چکیده
condensation reaction of urea, casein and formaldehyde in the presence of varying proportion of resorcinol under alkaline condition. All the prepared resins were characterized by free-formaldehyde content, free-phenol content, viscosity measurements and infrared spectroscopy (IR). The resin samples were cured isothermally at 120oC using two different curing agents, p-toluene sulphonic acid (PTS) and hexamine and also by differential scanning calorimetry on dynamic run to understand the curing behaviour of novel resin samples. The cured resins were characterized by IR and thermogravimetric analysis. The resin samples were employed for the fabrication of glass fibre and jute fibre reinforced composites, respectively by maintaining 2:3 and 3:2 proportion of resin: reinforcement. Thus prepared composites were tested for their mechanical properties and resistance towards various chemicals. Dipak K. Raval*, Bhavil N. Narola, and Amit J. Patel

In the current work, we developed a facile synthesis of yolk/core-shell structured TS-1@mesosilica composites and studied their catalytic performances in the hydroxylation of phenol with H2O2 as the oxidant. The core-shell TS-1@mesosilica composites were prepared via a uniform coating process, while the yolk-shell TS-1@mesosilica composite was prepared using a resorcinol-formaldehyde resin (RF)...

Resorcinol-formaldehyde (RF) resin is a kind of excellent exterior-grade wood structural adhesive, which can be conveniently cold-set for various applications. In order to decrease the production cost, pyrolysis bio-oil from renewable bioresources was used to replace resorcinol to synthesize the bio-oil-resorcinol-aldehyde (BRF) resin. The effect of replacing resorcinol with bio-oil on the prop...
