Poly (itaconic acid) functionalized lignin/polyvinyl acetate
The physical, thermal, and mechanical properties of the composite resins were examined and correlated with the structure property relationship of the P(IA)-f-Lignin/PVAc resin composite. To evaluate the superiority of the P(IA)-f-Lignin/PVAc resins the wood adhesion strength has been compared with prior art literatures.
Characteristics of Non-plasticizer PVAc Resin for Wood
The properties of the laminated veneer lumber (LVL) composed of the boiled veneer of Rubberwood (Hevea brasiliensis) using polyvinyl acetate (PVAc) adhesives in various cold-pressing time and...
Characteristics of Non-plasticizer PVAc Resin for Wood
PVAc resin is primarily used for wood works and paper adhesion. However, the PVAc resin itself has the disadvantages that its viscosity is highly temper- ature-dependent and the work condition and viscosity get worse at the low temperature in the winter seasons.
Enhancement of Polyvinyl Acetate (PVAc) Adhesion Performance
Polyvinyl acetate is a clear, water-white, thermoplastic synthetic resin produced from its monomer by emulsion polymerization. PVAc is good adhesive for paper, plastics, metal foil, leather, cloth and wood, but it is also used as a general building adhesive [1,7,8]. PVAc sets through evaporation and diffusion of the water into the substrate
Aspects of the performance of PVAc adhesives in wood joints
Adhesive strength in thermosetting resins is enhanced by irreversible chemical reactions that create extensive networks within the adhesive layer and strong bonds to the wood substrate, leading to strong and durable joints that passed all of the performance evaluation tests. Most of the PVAc emulsions exhibited good adhesive performance in the
- What are the disadvantages of PVAC resin?
- PVAc resin is primarily used for wood works and paper adhesion. However, the PVAc resin itself has the disadvantages that its viscosity is highly temper- ature-dependent and the work condition and viscosity get worse at the low temperature in the winter seasons.
- Does PVAC resin have sustainability?
- Despite these advantages, PVAc resin don’t have sustainability as it is derived from non-renewable petroleum-derived resources. Usually, it forms a strong adhesive bond with porous surfaces like wood and paper, however its adhesive strength is restricted by the mechanical properties of the polymeric resin.
- How to prepare pvac@p(IA)-F-L composite resin for wood adhesive application?
- Here, we report a novel method for successful preparation of PVAc@P(IA)-f-L composite resin for the first time with high lignin content for wood adhesive application by simple blending of P(IA)-f-Lignin (20, 30, 40, 50, and 60 wt%) with aqueous emulsion of PVAc.
- What is pVAC resin?
- PVAc resin, as the one manufactured and in- PVAc monomer becomes a colorless transparent dustrialized first in Germany in 1924, is widely resin by polymerization if heated by adding a used for adhesives, paints and resins due to its small quantity of benzoyl peroxide.
- What is P(IA)-F-lignin in polyvinyl acetate (PVAc) composite resin?
- High concentration of P(IA)-f-Lignin into polyvinyl acetate (PVAc) to produce novel P(IA)-f-Lignin/PVAc composite resin. The PVAc composite resins exhibit outstanding enhancement of adhesion strength with wood failure. High concentration of biobased P(IA)-f-Lignin in PVAc composite resin would enhance sustainability and scope of bioeconomy.
- Does PVAC composite resin contain biobased poly(itaconic acid) functionalized lignin?
- Herein, for the first time, we report a PVAc composite resin with a high concentration of biobased poly (itaconic acid) functionalized lignin (P(IA)-f-Lignin) via tailoring the surface chemistry of lignin.
