Description
Technical field:
The manufacture method of a kind of color solid plate that the present invention proposes belongs to the processing method of wood utilization, and what be specifically related to is a kind of manufacture method of multi layer colour plate.
Background technology:
Cause large stretch of forest to be ruined owing to human a large amount of uses to natural timber now cause to the excessive felling of the woods, some precious seeds faces the danger of extinction.For this reason, the mankind have carried out large-scale artificial afforestration, but because there is various defectives in the timber of spontaneous growth, as scab, die for the sake of honour, natural defects such as black line, and the limit core aberration of self-sow, ftracture easily, STRESS VARIATION and crooked material defective, very fast because of the quick growing species of trees again owing to growing, itself material is just too soft, does not have decay resistance, though inflammable or the like defective is with after the rounding, to cut into slices and paste into veneer with colloid, but speed is given birth to the loose essence of wood and is not changed, and makes natural timber be very restricted in use, does not satisfy the requirement of human high-quality life far away.
Summary of the invention:
At the defective that existing timber exists, the purpose of this invention is to provide a kind of manufacture method that can overcome the defective of natural timber and effectively solve the multi layer colour plate of defectives such as the fast growing wood material is soft, not corrosion-resistant, inflammable.
The present invention also provides a kind of as the integrated solid wood board of the disclosed veneer of above-mentioned invention, and in its sheet material, every veneer of formation can adopt no seeds and different compound modes to carry out stacked combination as required.
A kind of manufacture method of color solid plate, its method is:
1) timber is processed into veneer
To become the thick veneer of 0.2mm-10mm as timber rotary-cut or the slicing that the artificial speed of raw material is given birth to wood or various pin, broad-leaf forest;
2) single-plate dyeing
The veneer of getting ready the dyeing case of packing into, and add the 2Kg-5Kg colorant according to every cubic metre of water, knock down then in the pressure vessel, temperature is controlled at 80 ℃-100 ℃, and humidity is at 60%-90%;
3) negative pressure of vacuum for the first time
Veneer after the dyeing is according to 1Kg-3Kg/cm 2Negative pressure is carried out the negative pressure of vacuum first time, time 20-30 minute;
4) vacuum pressed
According to 5Kg-8Kg/cm 2Vacuum pressed, time 30-60 minute;
5) negative pressure of vacuum for the second time
According to 1Kg-3Kg/cm 2Negative pressure is carried out the negative pressure of vacuum second time, time 10-20 minute;
6) oven dry
Send into drying plant after the veneer that dyeing is good takes out, oven dry is to moisture 10%-14%;
7) dipping
Put into the impregnation tank that contains the colloid maceration extract after the veneer that oven dry is good takes out and carry out impregnation, adjust temperature to 36 ℃-80 ℃;
8) vacuum pressed 4Kg-8Kg/cm 2, time 10-40 minute;
9) negative pressure of vacuum 3Kg-5Kg/cm again 2, time 10-20 minute;
10) veneer that impregnation is good is sent into drying plant after taking out, and dries to moisture content 6%-8%;
11) will dye and reach the needs of the good veneer of impregnation, and stack and carry out pressing after arranging according to collocation; Pressure is at 8Kg-20Kg/cm 2, temperature is at 80 ℃-180 ℃, and pressing time was at 30-240 minute.
The timber that described artificial speed is given birth to wood or various pin, broad-leaf forest can be poplar, paulownia wood, birch or lotus wood, in the first time of negative pressure of vacuum and for the second time after the negative pressure of vacuum, utilizes the slow pressure release of valve to carry out back pressure, thereby reaches tank body external and internal pressure unanimity.
The bake out temperature of the veneer that described dyeing is good is between 70 ℃-90 ℃.
Veneer behind the described impregnation needs with glue spreader surperficial gel resin to be carried out on the veneer surface, and described pressing contains the process of pressurization repeatedly.
The process of described pressurization pressing can be three times pressurization, is pressurised into temperature at 30 ℃-60 ℃ for the first time, and pressure is 2-4Kg/cm 2, the time is 2-10 minute, is pressurised into temperature at 60 ℃-70 ℃ for the second time, pressure is 2-4Kg/cm 2, the time is 3-20 minute, is pressurised into temperature for the third time at 80 ℃-110 ℃, pressure is 7-10Kg/cm 2, the time is 8-20 minute, closes heater afterwards, is cooled to 30 ℃-40 ℃ naturally.
Described firing equipment and drying plant are Boiler Steam or deep fat thermal power unit, and needed pressure is set to pressurized tank.
The used colloid maceration extract of described immersing glue process can be natural glue or for phenolic resin glue or for melamine environmental protection resin glue.
The solids content of described phenolic resin glue is 60%-90%.
The present invention can make natural speed give birth to wood to have colorful color, has environmental protection, fire-retardant, moistureproof, corrosion-resistant, wear-resisting, not yielding, characteristics that plasticity is strong simultaneously.
