Abstract

The invention discloses a rigid foamed plastic which comprises a component A, a component B and filling materials, wherein the component A comprises polyether polyols, a foam stabilizer, a catalyst, a foaming agent and a cross-linking agent; the component B comprises isocyanate; the filling materials comprise inorganic powder filling materials, plant powder filling materials and fiber filling materials. By utilizing the characteristics of the reaction molding of rigid foams, the rigid foams are bonded with the inorganic powder filling materials, the plant powder filling materials and the fiber filling materials, so that the performance of the rigid foams is enhanced by the matching combination of three types of the filling materials. Thus, the synergistic effect for improving the performance of the rigid foamed plastic is exerted. Therefore, the rigid foamed plastic is high in strength and good in dimensional stability; the problems of expansion/shrinking and deformation of the rigid foamed plastic during a storage process are solved. As a result, the holding capacity of the rigid foamed plastic to insertion components such as nails, pins and the like is improved; the manufacturing cost is lowered.

Description
