The renewable lignocellulosic sources for biocomposites have received much attention in recent years because of the shortage of forest resources. The surface of rice straw was pretreated through humid-heat and chemical modification by coupling reagent which could improve the adhesion capacity between urea formaldehyde resin and rice straw. Meanwhile, the process of fabricating straw board was explored in this paper. The experimental data shows that the straw boards with perfect properties are prepared under the temperature of 150 ℃, the pressure of 15 MPa, the hot pressing time of 8 min, the mass ratio of resin powder to water of 1:1, and the urea formaldehyde resin adhesive content of 15%(mass fraction). The straw boards prepared by 3-glycidyloxypropyltrimethoxysilane(KH560) as surface modification reagent show better properties than those by KH550 and untreated rice straw.
