Optimization and Characterization of Melamine Urea Formaldehyde (MUF) Based Adhesive With Waste Rubber Powder (WRP) as Filler

Optimization and Characterization of Melamine Urea Formaldehyde (MUF) Based Adhesive With Waste Rubber Powder (WRP) as Filler

Fillers are added in adhesive formulation to minimize the utilization of resin in wood based products. Waste Rubber Powder is being used as wood adhesive filler in order to change the research work from waste to wealth. In this work, Melamine Urea Formaldehyde (MUF) resin was produced in the laborat...

Waste Rubber Powder is being used as wood adhesive filler in order to change the research work from waste to wealth. In this work, Melamine Urea Formaldehyde (MUF) resin was produced in the laboratory and waste rubber powder was subjected to chemical modification by using oxidizing agents such as 20% nitric acid, 30% hydrogen peroxide and acetone solution were added to the Melamine Urea Formaldehyde (MUF) resin in identifying the best chemically modified waste rubber powder for interior plywood manufacturing using a laboratory press.

Response surface methodology (RSM) software was used for identification of the optimum temperature and pressing time for wood adhesive performance. The optimum parameters investigated in this experiment was in the temperature range from 100 to 175°C at fixed pressing time at 150sec while in the time range from 50 to 450s at fixed prssing temperature at 125˚C.
