Abstract
The production method of veneer board as container floor board includes the following steps: cutting eucalypt log into single plate with a certain size, drying said single plate and making its water content be less than 12%, coating double faces of said single plate with glue, laminating the single plates to the defined thickness, cold-pressing them at room temp. to form blank plate, then hot-pressing the obtained blank plate at 130-145 deg.C and 1.2-1.6 MPa so as to obtain the invented product. Said invention sues the eucalypt as raw material to produce the invented veneer board.
Description
Technical field
The present invention relates to the production material and the production and processing technology thereof of veneer board for container floor board.
Background technology
China all the time, the production material of container floor is all Southeast Asia clone's wood, clone's wood belongs to wildwood, through felling for many years, now, not only natural clone's wood does not satisfy the demand of growing container floor, and a large amount of fellings of Southeast Asia wildwood have caused the concern in the world to the destruction of earth environment.In order to reduce the demand of container production to natural wood, there are some researchers to propose some container is replaced the scheme of timber floor with steel plate, but still adopt timber floor more economical the container of most of purposes, more share.
Eucalyptus is one of chief species of world artificial forest, and aboundresources is mainly used to process building form and general glued board now.Container circle thinks that always its material is not suitable for the production and processing veneer board for container floor board.
Summary of the invention
One of the technical problem to be solved in the present invention is, a kind of veneer board for container floor board is provided, and it is abundant to have raw material sources, and cost is low, helps the advantage of ecological environmental protection.
Two of the technical problem to be solved in the present invention is, a kind of veneer board for container floor board production method is provided, and adopts this method, can be main raw material(s) with the eucalyptus, and production and processing goes out quality and the satisfactory veneer board for container floor board of performance.Replace natural wood thereby reach, preserve the ecological environment the purpose that reduces production costs with artificial wood.
The technical scheme that the present invention solves first technical problem is: a kind of veneer board for container floor board, form by the overlapping back hot pressing of multilayer Wooden veneer, and it is characterized in that, in the described veneer, contain the eucalyptus veneer at least.
In the veneer board for container floor board of the present invention, described veneer can all be the eucalyptus veneer, also can be eucalyptus veneer, a kind of or several homemade materials and Imported timber veneer, as veneer and Imported timbers such as homemade material birch, poplar, larches, combine as veneers such as Southeast Asia clone's wood, African Jiangbing Wood and the little mangroves of gram Lay.
The technical scheme that the present invention solves second technical problem is: a kind of veneer board for container floor board production method, it is characterized in that, and comprise the steps:
A, log is cut into the veneer of certain size, and is dried to moisture content less than 12%; Wherein at least a portion log is an eucalyptus;
B, moisture content is met the requirements of an amount of glue of a part of double spread in the veneer;
C, according to the size of the glued board that will produce, the veneer of cementing not and the veneer that has been coated with glue are stacked alternately to predetermined thickness, and the formation blank flat of at room temperature colding pressing, pressure is not more than the pressure that will carry out hot pressing;
D, under 130--145 ℃ temperature, the pressure that applies 1.2-1.6MPA pressure through the blank flat of colding pressing is carried out hot pressing, continue hot pressing 35-55 minute.
In the inventive method, described log can all be an eucalyptus; Described veneer can all be the eucalyptus veneer; Described glue can be phenolic aldehyde glue; Pressure to the hot pressing of described multilayer veneer can be 1.2-1.4MPA, and the hot pressing duration can be 40-55 minute, and the temperature during hot pressing can be 130-145 ℃.
In the inventive method, described log can all be an eucalyptus; Described veneer can all be the eucalyptus veneer; Described glue can be phenolic aldehyde glue; Pressure to the hot pressing of described multilayer veneer can be 1.4-1.6MPA, and the hot pressing duration can be 35-45 minute, and the temperature during hot pressing can be 140-145 ℃.
In the inventive method, described veneer can be eucalyptus, a kind of or homemade material of seeds, Imported timber veneer, as veneer such as homemade material birch, poplar, larch and and Imported timber clone's wood and veneers such as Jiangbing Wood, the little mangrove of gram Lay; Described glue can be phenolic aldehyde glue; Pressure to the hot pressing of described multilayer veneer can be 1.2-1.4MPA, and the hot pressing duration can be 40-45 minute, and the temperature during hot pressing can be 135-145 ℃.
Adopt aforesaid veneer board for container floor board of the present invention and production method thereof, have raw material sources and enrich, production technology is simple, and properties of product are stable, and production cost is low, helps advantages such as ecological environmental protection.Below in conjunction with drawings and Examples the present invention is described in further detail.
