Abstract

Current study exponentially investigated the effect of curing time and temperature on shear and peel out strength of adhesive joints, by mixing  polyvinylpyrrolidone PVP k30 with polyvinylealcohol PVA. In this work, the adhesive prduced from dissolve 16 gm of polyvinylpyrrolidone and 8 gm of polyvinylealchol with 50 ml of water. The study focused on effect of variables with 5 MPa constant pressure. Therefore, study five temperatures (200, 215, 225, 240 and 265) °C and two values of  time 10, 20 min. on the shear and peel strength will study. The shear and peel out results showed that best properties found at 225 °C and time of 10 min., reaching overhead hanging to 1259 N, 101N respectively , that there is an increase in resistance of adhesive with the increase in temperature and up to 225 °C, and then there is decrease resistance and up to 265 °C at the time of 10 min. .
