Abstract

The invention discloses high-strength composite plywood which comprises an intermediate fiber board, upper-layer veneer and lower-layer veneer, wherein the upper-layer veneer is fixedly connected withthe upper side of the intermediate fiber board; and the lower-layer veneer is fixedly connected with the lower side of the intermediate fiber board. A preparation method of the high-strength composite plywood comprises the following steps: a bonding agent is uniformly sprayed onto the upper side and the lower side of the intermediate fiber board; the upper-layer veneer and the lower-layer veneerare correspondingly bonded to the upper side and the lower side of the intermediate fiber plate; and the high-strength composite plywood is obtained through hot-press forming. The high-strength composite plywood disclosed by the invention has the characteristics of being high in bonding strength as well as resistant to acid and alkali.

Description

technical field [0001] The invention belongs to the technical field of plywood. More specifically, the present invention relates to a high strength composite plywood. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for boards has also risen rapidly, which has made the price of raw wood rise day by day. Plywood is a kind of man-made board formed by mutual grouping and glue pressing of wooden veneers. Its development and utilization have important practical significance for alleviating the contradiction between wood supply and demand and protecting forest resources. However, most of the existing plywood is a three-layer or multi-layer board-like material formed by peeling wood sections into veneers or sliced ​​into thin wood, and then glued with adhesives. The problem of utilization, therefore, the development of a composite plywood is of great significance to the protection of forest resources. Contents of the ...
