In this paper, it was determined that the technological process of OSB overlaid with resin impregnated paper. The main technological parameters were obtained with the compound optimization method.As a result, the optimal manufacturing technology was as following:resin spread content 170 g/m 2,hot pressing time 9 min, hot pressing temperature 158 ℃,hot pressing pressure 1.85 MPa. And the testifying experiment showed that the optimal technological parameters were both practical and reliable.
