Embodiment Construction

[0069] Artificial fast-growing wood natural plywood, including a series of artificial fast-growing wood plywood products made of vegetable protein adhesives: ordinary plywood, laminated veneer lumber, blockboard, finger-jointed board, technical wood. Taking the best process conditions as an example, the production methods of each product are described in detail below:

[0070] 1. The production method of ordinary plywood, taking 7-layer plywood as an example:

[0071] (1) Veneer pretreatment step: sort the raw veneer, and use a mesh belt dryer to dry the veneer to a moisture content of about 12%. Manually repair the surface defects of the veneer after drying, and store it according to the specifications.

[0072] (2) Gluing and billet assembly steps: the veneer in the direction of the long core is pressed at 200g / m 2 (Single-sided) sizing amount is double-sided gluing, under the hot-air drying condition of temperature 75 ℃, the moisture content of sizing board is reduced to ...

Abstract

The invention relate to an artificial quick-growing natural plywood, which comprises a common plywood, a laminated veneer lumber, a blockboard, a wedge joint boardand and a technical wood. A dhesive obtained by chemically modifying a plant protein raw material is used for the invention, and the drying and dewatering are carried out after the steps of glue spreading and assembly in the process of processing the plate. The obtained plywood has a high bonding strength, no harmful gases such as aldehyde, beneze, etc., are discharged in the process of processing the plate and during the using period, and the waste plate does not cause the environmental contamination during the degradation in a natural environment. The artificial quick-growing natural plywood fundamentally terminates the harm done by the material selection and adhesives to the environments and the health of the human beings, realizes true production of environment-friendly artificial boards, and ensures that the artificial boards have the same natural properties as the saw log products made from raw wood both in process of production and use.

Description

technical field [0001] The invention belongs to the technical field of artificial board manufacture, in particular to a plywood produced by using artificial fast-growing wood and a fully degradable vegetable protein adhesive and a production method thereof. Background technique [0002] Wood-based panels refer to the board surface materials that are combined by mechanical processing or chemical treatment of wood and its corner waste, wood chips or other plant stems and leaves. Wood-based panels have many advantages such as light weight, certain strength, uniform elasticity and strength than raw materials, small shrinkage, not easy to crack and warp; can be spliced ​​with small materials; easy to process into various properties, and meet various purposes. It can be said that the formation and development of the wood-based panel industry indicates that human beings have made great progress in the effective use of forest resources. In recent years, my country's wood-based pane...
