LIGNIN-BASED PHENOLIC ADHESIVES, RELATED COMPOSITIONS, AND RELATED METHODS
20230056241 · 2023-02-23 ·

The disclosure relates to adhesive compositions, including non-crosslinked resins and crosslinked/cured adhesives joining substrates, as well as related methods for making the compositions and articles. Compared to a conventional phenol (P) and formaldehyde (F) resin, the disclosed methods and compositions use lignin (L) and higher aldehydes (A) as corresponding replacements to provide an analog to a conventional PF resin with biobased reactants. Due to the differing reactivity of the LA components compared to the PF components, the initial condensation reaction between ortho-reactive sites in the lignin and the aldehyde is controlled to prevent gelation of the aqueous reaction mixture while reacting substantially all of the LA reactants to provide a non-crosslinked resin reaction product. The resin reaction product can then be cured at high temperature/high pressure conditions to provide a crosslinked adhesive, for example joining two substrates.

WATER-BASED PAINT, CERAMICS, AND METHOD OF DECORATION

Ceramics are capable of reducing color irregularities and uneven coating, hard to dissolve into glaze, and excellent in fixation. A water-based paint contains a coloring material, first cellulose nanofibers having a lignin content of 20 to 40 mass % and a water retention of 150 to 300%, and second cellulose nanofibers having a higher viscosity compared to the first cellulose nanofibers, and the water-based paint has a B-type viscosity of 600 cps or higher. Ceramic ware or glassware or the like having painting made on a green body of which surface is formed of silicic acid or silicate compound as a main component, with the water-based paint.

A METHOD FOR OBTAINING A LIGNIN OIL COMPOSITION USING A COMPRESSED GAS AND ACID ASSISTED PROCESS

A process for the production of a liquid lignin composition, in particular to a method for obtaining a lignin composition using a compressed gas and acid assisted process, wherein a lignocellulosic biomass feedstock is treated with a polar organic solvent using an inorganic acid to assist in the release of lignin into the polar organic solvent and the use of compressed gas to keep the polar organic solvent in its liquid phase.

WAX-ORGANIC EXTENDER EMULSION AND METHOD FOR MANUFACTURE THEREOF

A wax-extender emulsion including a plurality of wax-extender complex particles suspended in water is described. A wax-extender complex includes a wax component, an organic extender component and a surfactant that stabilizes the wax component and the organic extender component collectively to form the wax-extender complex. The wax-extender emulsion comprises from 2 wt% to 30 wt% organic extender. During manufacturing, the organic extender and wax component are emulsified and homogenized together to produce the wax-extender emulsion. The wax-extender emulsion can be co-applied as a mixture with adhesive resin during wood-based composite manufacturing.
