Abstract

Background and aims: Iran forests are unable to supply required wood for wood industries including particleboard industry. Therefore, using of non-forest resources such as agricultural residuals is inevitable. Among agricultural products, wheat from quantity point of view is at the second category. After harvesting, wheat stem as agricultural residual is left in the farms in which part of it is used for animal feeding. IN Iran, wheat residual forms more than 54% of all agricultural residuals. Regarding chemical structure of wheat straw, UREA FORMALDEHYDE resin is not suitable for bonding of wheat straw particles. On the other hand, formaldehyde emission during production and use is another problem. In this study, application of natural resin of Acrilated epoxidized soya oil (AESO) as a resin for bonding wheat straw particles in producing particleboard was investigated and some of its properties were evaluated.Method and materials: In this study, first soya oil was epoxidized using FORMIC ACID and HYDROGEN PEROXIDE. Then, Acrylic acid was added to epoxidized soya oil so ASEO resin was made. AESO resin properties were evaluated. In order to study resin performance, some boards were manufactured from wheat straw and AESO resin (8 and 13%) using hot press with temperature of 200degree centigrade, press pressure of 30 bar and press time of 8, 10 and 12 minutes. Physical and Mechanical properties such as Modulus Of Rupture (MOR), Modulus Of Elasticity (MOE), Internal Bond (IB), Thickness Swelling (TS) and Water Absorption were measured. Collected data was analyzed using Analysis of Variance and SPSS software.Results: FTIR results showed that epoxdizing process was conducted successfully so epoxy groups were stationed on soya oil. Investigation on progress of reaction of acrylic acid with epoxidized soya oil was proved by H- NMR technique. Opening of epoxy rings was an indication of progress, Results of physical and mechanical evaluation of board properties showed that regarding boards made from wheat straw and UF resin, Wheat straw boards made using AESO resin had better properties so that IB, MOR and MOE improved 110, 137 and 13.6 percent and WA and TS enhanced 48 and 69 percent. These results are an indication of suitable performance of AESO resin.
