Dataset for chemorheological and rheokinetic analysis of carbohydrate-HMF-amine adhesives

Abstract

The work consists of primary and analysed data from rheological measurements of carbohydrate-hydroxymethylfurfural-amine adhesives. The studied adhesives are a bio-based alternative to conventional wood adhesives. The rheological properties were studied at different temperatures in isothermal (80, 90, 95 °C) and non-isothermal (20–120 °C) oscillatory measurements. Non-isothermal rheological measurements were used for the determination of the activation energy based on Vyazovskin's isoconversional method. The viscosity profile of the adhesives, determined from isothermal measurements, was fitted by an empirical model. The viscosity kinetic constant can be obtained from this empirical model and used in further rheokinetic analysis. Data from density and swelling experiments was measured for the characterization of the adhesive network. The determined polymer-solvent interaction parameter is included in the collected data. The provided datasets were used in the investigation of the reactivity and curing reaction of the studied adhesives. A discussion and interpretation of the data can be found in the previous publication [1] .

Determination of the Gel Point of Formaldehyde-Based Wood Adhesives by Using a Multiwave Technique

“…Thoma et al 48 showed that for carbohydrate−HMF− amines, the CP coincides with the GP and found the GP by means of multiwave tests (MW tests) at tan δ = 1. Du et al 49 performed time sweep tests (TS tests) at three different frequencies to determine the GP based on the frequency independence of tan δ for a polythiourethane system.…”
