Abstract

Adhesive is a substance that holds materials together by surface attachment, while wood adhesive is a substance that is used to hold plywood for furniture works. This substance is essential and has universal applications. Thus the aim of this research work is to produce it using cassava starch as a base binder. Starch is also used in industries to produce ethanol and glucose for textile industries, laundry and paper adhesive industries.
rn
rnIt is of great importance to paper, wood and furniture industries and the need to produce a more stable adhesive locally to minimize cost remains the investigating factor for embarking on this research work.
rn
rnThe method of wood adhesive production used in this work was the questionnaire work was the gelatinization method. In the production, the optimum gelatinization temperature was found to be 800c while the optimum temperature of dextrin formation is 1400c. The production involves the souring of the starch from cassava, determination of the various additives employed in the production. The materials used in the production works were sourced in line with the objectives of the research. The following components were used: starch extracted from cassava which is responsible for the adhesion force that holds two bodies together, calcium carbonate (CaCo3) for viscosity improvement, formaldehyde as preservative, natrosol cellulose as a thicker and water as solvent.
rnExperimental analysis was based on all the factors that influence the stability of an adhesive example pH values, viscosity, tack time, boarding strength etc. the values obtained were compared with the standard brands and were found to compare favourable with other standard adhesives.
rn
rnFormulation B showed the most desirable characteristics and hence is the optimum sample.
rnAn adequate cost analysis was also carried out to determine the feasibility of the project on a commercial venture. Thus, a locally sourced product (wood adhesive) that can complete with similar product in terms of properties but at a much reduced cost was produced. The shelf life and teak time of the product were determined and found to be good. The wood adhesive was established to be water resistant.
