  1. 1. Synthesis and characterization of a greener poly(vinyl acetate) adhesive

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Xiuting Zhang; [2023]
    Nyckelord :poly vinyl acetate -grafted-chitosan; chitosan; poly vinyl acetate ; ceric ammonium nitrate; green adhesive; poly vinyl acetat -ympad kitosan; poly vinyl acetat ; ceriumammoniumnitrat CAN ; grönt lim;

    Sammanfattning : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. LÄS MER

  3. 2. Reaction Mechanism between Chitosan and Cerium(VI) Ammonium Nitrate for Production of a Greener Poly(Vinyl Acetate) Adhesive

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Mårten Schollin; [2021]
    Nyckelord :Chitosan; Poly vinyl acetate ; Cerium IV ammonium nitrate ; Grafting; Reaction mechanism;

    Sammanfattning : Poly(vinyl acetate) (PVAc) has a major application as an indoor wood adhesive. Low water stability is however, one of the greatest drawbacks of PVAc. By grafting PVAc from a chitosan (CS) backbone (CS-graft- PVAc) water stability of adhesive is increased while good mechanical and adhesive properties are retained. LÄS MER

  4. 3. Exploring the sustainability potential of an algae-based wood adhesive : Comparative and explorative environmental life cycle assessment of algae- vs. formaldehyde- based adhesives for particleboard production

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Charlotte Rasche; [2020]
    Nyckelord :life cycle assessment; particleboard; bio-adhesive; wood-adhesive; bio-resin; algae; macroalgae; seaweed; kelp; formaldehyde; greener production; environmental impacts; biobased; design for the environment;

    Sammanfattning : Adhesives used for wood composites such as particleboard are conventionally of petrochemical nature with formaldehyde as a base substance and represent a pain point in the industry due their toxic emissions. Consequently, adhesives are subject to an agenda to develop more benign, low-impact alternatives. LÄS MER

  5. 4. Synthetic Functionalization of Colloidal Lignin Particles for Wood Adhesive Applications

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Fusi Alexander Deen; [2020]
    Nyckelord :Lignin; Colloidal Lignin Particles; Glyoxal; CLPs; adhesive; Lignin; kolloidala ligninpartiklar; glyoxal; CLP; lim;

    Sammanfattning : Functionalizable spherical colloidal lignin particles (CLPs) represent a valuable asset for the valorization of lignin side-streams from the pulp industry. The spherical structure allows for the circumvention of the heterogeneous and poorly dispersible structure of the biopolymer. LÄS MER

  7. 5. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano Cellulose

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Johan Ekstrand; [2019]
    Nyckelord :Nano Cellulose; Fibrillated cellulose; Wood Adhesive; Shear strength; Adhesive Enhancement; Formaldehyde adhesive; Phenol Formaldehyde;

    Sammanfattning : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. LÄS MER
