Novel composite plate and production method thereof

Abstract

The invention discloses a novel composite plate. A shaving board is taken as a center layer; bamboo split plates dipped with phenolic resin glue are respectively laid on the upper and lower surfaces of the shaving board; wooden mono-plate layers are respectively laid on the upper and lower outer surfaces of the bamboo split plates; phenolic resin glue dipped paper is respectively adhered to the upper and lower outer surfaces of the wooden mono-plates. A production method of the novel composite plate comprises the following steps: step 1, preparing a shaving board by shaving a wooden sheet or a bamboo sheet; step 2, dipping the bamboo split plates in the phenolic resin glue and then removing the water; step 3, drying the bamboo split plates which are removed from water; step 4, respectively laying a bamboo split plate layer on the upper and lower outer surfaces of the shaving board prepared in the step 1; step 5, distributing glue on one surface of each wooden mono-plate, and respectively laying a wooden mono-plate on the upper and lower outer surfaces of a blank bamboo split plate; step 6, respectively adhering the upper and lower outer surfaces of the blank wooden mono-plate plates with phenolic resin glue dipped paper; step 7, pre-pressing the assembled blank plates; step 8, thermally pressing the pre-pressed blank plates; step 9, sawing and milling edges, and slitting to obtain a finished product.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel composite board and a production method thereof. Background technique [0002] At present, the plywood used for the bottom plate of the container, the core layer of the plywood is medium density fiberboard or particle board, and the surface board is tropical hardwood. Raw materials increase the cost, and the overall strength is insufficient. [0003] In the production process of ordinary bamboo-wood plywood, it is generally made of multi-layer wood veneer and bamboo veneer after hot pressing. Among them, the bamboo veneer is not impregnated in the production process, but because bamboo contains more Nutrients such as sugar and starch, wood and bamboo products are prone to decay, mildew and insects in warm and humid environmental conditions, which shortens the service life of the product. Contents of the invention [0004] The purpose of the present invention is to pr...

Problems solved by technology

[0002] At present, the plywood used for the bottom of the container, the core layer of the plywood is medium density fiberboard or particle board, the surface board is tropical broad-leaved hardwood, the configuration of the veneers on both sides of the medium density fiberboard or particle board is symmetrical, and tropical hardwood is used as the production Raw materials increase the cost, and the overall strength is insufficient

[0003] In the production process of ordinary bamboo-wood plywood, it is generally made of multi-layer wood veneer and bamboo veneer after hot pressing. Among them, the bamboo veneer is not dipped in the production process, but because bamboo contains more Nutrients such as sugar and starch, wood and bamboo products are prone to rot, mildew and insects in warm and humid environmental conditions, shortening the service life of the product
