Technical lignins modified by hydroxymethylation for the production of decorative laminates: Synthesis, characterization and mathematical modelling
Technical lignins are natural and renewable poly-phenolic polymers obtained mainly as a subproduct from the pulp industry. It presents a complex structure that depends on the wood type and the pulping process adopted to ...
Synthesis and mechanical characterization of high pressure laminates modified with Kraft lignin
(255th ACS National Meeting Exposition New Orleans, 2018-04)
Phenol-formaldehyde resins (PF) are thermosetting polymers used as adhesives for plywoods and other structural wood products including high pressure laminates (HPLs). HPLs are composite materials comprised of a paper-based ...
Effect of Kraft Lignin from Hardwood on Viscoelastic, Thermal, Mechanical and Aging Performance of High Pressure Laminates.
(Waste and Biomass Valorization, 2017-07-10)
In this work, the synthesis and characterization of phenol-formaldehyde resols modified with 10, 20 and 30 wt% of Kraft lignin (a waste from pulp industry) from hardwood were studied. In all cases, the Kraft lignin ...
