Abstract

이 발명은 표리면이 열 경화성 수지로 보강 된 합판을 제조하는데 관계되는 것임. 합판의 표리면을 구성하는 베니아를 석탄산 수지 초기 축합물에 침지하여 베니아의 목질부 내부까지 석탄산 수지가 침투되게 한 후 이 베니아가 합판의 표리면을 형성하도록 공지의 합판 제조 공정에 따라 합판을 제조함. 공지의 합판 제조 공정중의 열압 공정중에 베니아의 표면에 피복된 석탄산 수지 초기 축합물이 경화되면서 매그럽게 되므로 완성된 합판의 표면 연마 공정이 생략됨.This invention relates to the manufacture of plywood whose front and back surfaces are reinforced with thermosetting resins. Veneers constituting the front and back surfaces of the plywood are immersed in the initial condensate of the phenolic resin to allow the phenolic resin to penetrate into the woody part of the veneer, and then the plywood is manufactured according to a known plywood manufacturing process to form the front and back surfaces of the plywood. . Since the initial condensate of the phenolic resin coated on the surface of the veneer is smoothed while curing during the hot pressing process of the known plywood manufacturing process, the surface polishing process of the finished plywood is omitted.
