Abstract

A core-board with novel structure features that its both surface plys and core ply are all the single board with the thickness of more than 4 mn. Its production method includes using the rotating cutter to cut timber for obtaining single board with more than 4 mm of thickness, drying for 1-4 days, gluing their together to obtain three-ply board, abrading both surfaces, and gluing veneer. Its advantages are high utilization rate of timber (80-90%), saving electric energy by 60% or more, simple method, and high performance and quality of product.

Description

Core-board with new structure and production technology thereof

Technical field:

The invention belongs to a kind of core-board product and production technology thereof.

Background technology:

The core-board that is used for interior decoration at present is made of the thick central layer of the bonding one-tenth of not isometric small strip 14.2mm, whole 1.2mm, 1.5mm or thick panel and the whole musculus cutaneus bonding of putting up of 1.8mm.Production technology is earlier log saw to be processed into the thick not wide square bar of 55mm, and volume recovery is 65%; Then with the square bar piling, carry out 1-3 month air dry, with dry about 10 days of laggard steam kiln or fiery kiln drying, the every square metre of dry expense 80-120 of square bar unit; The square bar that oven dry is good carries out planer, thicknesser, multiple blade saw, little cross cut saw and is processed into small strip, and volume recovery is 58%; Splice central layer with small strip then, rim charge needs finger, and 1.3 * 2.5 meters central layers are pieced together with the jigsaw machine in the centre, the thick panel of upper and lower surface bonding 1.6mm of central layer, last sanding, the thick veneer of stickup 0.3-0.4mm.The deficiency that above-mentioned core-board and production technology exist is: because the central layer of product partly is spliced, thereby influence the working strength and the engineering decorative quality of product, simultaneously owing to the outmoded backwardness of production technology, cause volume recovery low, waste is big, complex process, cost height.

Summary of the invention:

The purpose of this invention is to provide a kind of core-board with new structure and production technology thereof, improve product structure and production technology, improve the working strength and the product quality of product, improve volume recovery, save production equipment, personnel, place, reduce production costs.

The objective of the invention is to be achieved through the following technical solutions; Core-board with new structure is made up of middle central layer, upper and lower panel and veneer skin bonding, and it is characterized in that: middle central layer and upper and lower panel all adopt the veneer of 4mm-10mm thickness.Production technology is as follows, earlier log is peeled into the veneer of 4mm-10mm thickness with peeler, advanced dry kiln then dry 1-4 days, the veneer that drying is good is as middle central layer and upper and lower panel, middle central layer and upper and lower panel be synthetic three layers of joiner substrate behind gluing, last top and bottom coarse sand light, glue musculus cutaneus fine sand light.

The present invention compared with prior art has following advantage; 1, increase substantially volume recovery, volume recovery reaches 80-90%, saves significantly, saves timber more than 60%, and saves energy is simplified technology more than 60%, and saving equipment, producers, production site etc. reduce cost more than 30%; Improve product structure, improve product working strength and quality.

Description of drawings:

Fig. 1 is a product structure schematic diagram of the present invention.

The specific embodiment:

See Fig. 1, earlier the log of poplar is peeled into the veneer of 4-10mm thickness with peeler, volume recovery 80-90%, advanced dry kiln then dry 1-4 days, every cubic metre of dry expense is a 20-30 unit, and the veneer that drying is good is as central layer 3 and upper and lower panel 2, and middle central layer 3 and upper and lower panel 2 are bonded into three layers of joiner substrate behind gluing, at last with above and below coarse sand light, the veneer skin 1 that gluing 0.03mm-0.04mm is thick, carry out fine sand light.The specification of core-board is wide 1.22m, long 2.44m, and thickness is respectively three kinds of 0.012m, 0.015m and 0.018m.

Claims

1, a kind of core-board with new structure is made up of middle central layer, upper and lower panel and veneer skin bonding, and it is characterized in that: middle central layer and upper and lower panel all adopt the veneer of 4mm-10mm thickness.

2, a kind of core-board with new structure production technology, it is characterized in that: the veneer that earlier log is peeled into 4mm-10mm thickness with peeler, advanced dry kiln then dry 1-4 days, the veneer that drying is good is as middle central layer and upper and lower panel, middle central layer and upper and lower panel are bonded into three layers of joiner substrate behind gluing, at last with top and bottom coarse sand light, glue musculus cutaneus fine sand light.
