Waterproof dense board

Abstract

The invention relates to a waterproof dense board. A manufacturing process of the waterproof dense board comprises the following steps of: rubber mixing molding, wherein bits of wood are formed by an adhesive obtain a dense board; and carbonization processing, wherein the dense board is placed into a hot press which is used for uniformly baking the dense board at a high temperature in a convection manner and drives a packing apparatus to synchronously press and pack the dense board in the high-temperature backing process, and a working temperature of the high-temperature backing process is between 185 DEG C and 250 DEG C, thereby obtaining the waterproof dense board.

Description

technical field [0001] The invention relates to a dense board, especially a waterproof dense board. Background technique [0002] Due to its excellent tactile and visual effects, wood is widely used in various building decoration and furniture materials. However, with the rapid growth of the earth's population, a large amount of natural resources are consumed, and forest logs are affected by a large number of Due to the growing scarcity of felling, the price of wood will increase, and the cost of building decoration and furniture production will be greatly increased. Therefore, based on the above-mentioned shortcomings of too high wood cost, some operators have gradually developed a dense board. Because dense boards are The excess wood fragments after cutting the board are mixed with glue to form, thereby reducing the cost of using logs.

[0002] Due to its excellent tactile and visual effects, wood is widely used in various building decoration and furniture materials. However, with the rapid growth of the earth's population, a large amount of natural resources are consumed, and forest logs are affected by a large number of Due to the growing scarcity of felling, the price of wood will increase, and the cost of building decoration and furniture production will be greatly increased. Therefore, based on the above-mentioned shortcomings of too high wood cost, some operators have gradually developed a dense board. Because dense boards are The excess wood fragments after cutting the board are mixed with glue to form, thereby reducing the cost of using logs. However, due to the excellent water absorption of the wood fragments of the dense board, the dense board is easy to be damaged Changes in moisture will cause deformation, shrinkage, and swelling, which will affect the bonding effect of its wood chips. Moreover, due to the excellent water absorption of the wood chips of the dense board, it also provides a humidity environment for the growth of wood decay bacteria, making the dense board easy. Decayed by insects, which greatly reduces the durability of the dense board. On the other hand, due to the low bonding strength of the wood fragments of the dense board, when the user assembles it by screw lock, the structure at the screw lock Easy to disintegrate, causing inconvenience in assembly
