Abstract

The production process of fancy artificial plate blank with natural color difference includes the following main steps: selecting timber of different colors; cutting into timber tow or skein; mixing and drying; soaking with glue and drying; metering and feeding; pressing and curing; demolding and post-finishing. The fancy artificial plate blank or column blank has color spots and color grains of various natural colors in different directions. It may be made into different products, such as floor board, wall plate, furniture, etc and has high density, high strength, color and grain variety, completely new visual effect and other advantages.

Description

Natural color difference fancy artificial plate blank and production method thereof

Technical field

The present invention relates to a kind of artificial plate blank and production method thereof, is the true qualities difference according to wood raw material, forms the method that the different colours difference is made artificial plate blank.

Background technology

Wood-based plates such as the glued board of produced in conventional processes, fiberboard, with the combined artificial board material of plank, veneer clad can, color and luster is single, basically the point of penetration of doing appreciation and selecting for use with the nuance of textured pattern own and true qualities.CN1631628A discloses " method of bamboo carbonization ", former bamboo is carried out the charing of varying strength, cause white, faint yellow, bronze, coffee-like, coppery, bronze-colored, be directly used in house decoraton, with the effect that reaches pleasing, attracts people's eye, but this must adopt the charing operation, power consumption again consuming time, fiber also becomes fragile because of charing, influences intensity.

Summary of the invention

Above-mentioned deficiency at prior art, the objective of the invention is to design a kind of through selecting, timber with wood-fibred natural colored significant difference, crush-cutting becomes wood wool bundle material, make the natural color difference fancy artificial plate blank production method of slab again through batch mixing and drying, impregnation, high pressure, curing, also can provide color and decorative pattern to enrich, give the artificial plate blank of brand-new impression to society.

The invention has the beneficial effects as follows by selection the wood-fibred natural colored of timber, needn't adopt the charing operation, thereby wood-fibred is become fragile because of charing, after the batch mixing glue laminated, can produce the bright-colored wood-base fibre and particle panel material base of pattern equally, after putting in order, directly use, or cut into sheet material, make products such as pleasing furniture, floor, wallboard, beautify people's life.

Above-mentioned purpose can be from realizing by following measure: this natural color difference fancy artificial plate blank, mainly be plate body or column, and the surface of slab and cross section all are at least two kinds of piebald, flower stripe surfaces that the wood-fibred with obvious natural aberration is formed.Producing above-mentioned slab is mainly finished by the following step: heterochromatic timber selection, intercept become wood wool bundle and/or wood wool sheet, batch mixing and drying, impregnation and drying, metering and charging, compacting and curing again, the demoulding and back arrangement with crush-cutting.

The specific embodiment

The invention will be further described below in conjunction with embodiment.Produce this artificial slab, mainly need to finish through following steps:

(1) heterochromatic timber is selected: as selecting the little China fir that almost is white in color, yellow sandalwood, pink toon etc., use bright carpentery workshop raw material soon after cutting.

(2) intercept becomes the wood wool bundle with crush-cutting: the relative dimensions by press and mould decides intercept length, and whether juggle is removed the peel and made by oneself, its high pressure is rolled again vertically be cut into the wood wool bundle along silk, also can cut into slices earlier and afterwards be pressed into the wood wool sheet.

(3) batch mixing and dry: the wood wool bundle of different color and lusters (or sheet, down with) is mixed the kiln of packing into, and the moisture content that is dried to the wood wool bundle is about 10%, batch mixing once more also during kiln discharge.

(4) impregnation is with dry again: mainly adopt the water-fast glue of thermosetting, as phenolic resins, polyurethane adhesive etc.Be dried to moisture content and be about 18%.

(5) metering and charging:, press press effective area difference different, the thickness difference of desiring the pressing plate base, the difference of die volume because of the moisture content of the wood wool bundle of each batch, need calculate reasonably wait to press the weight of wood wool bundle after, be fed into machine again or go into mould.

(6) compacting and curing: pressure 〉=10Mpa are solidified again.

(7) demoulding and back arrangement: after the demoulding slab is cut end and wait the rear finishing duplex work, just can make plate body or column, and the piebald surperficial and longitudinal and transverse, that the oblique section all is the woody look color and luster of different color and lusters, spend the slab of stripe surface with sides cut.

Embodiment 1:

To be cut into the long juggle of 200cm after path China fir that cut down in the recent period and the toon peeling, crush-cutting becomes the wood wool bundle in the roll-in filament cutter respectively, selects about 3/4 toon tow, select 1/4 Chinese fir wood tow to mix again after, be dried to moisture content 10%, tie up impregnation, advance kiln again and be dried to moisture content 18%, separate bundle during kiln discharge and mix again, before suppression process, get earlier and expect the back charging of weighing, in press press or pressing mold,, carry out heat cure with after the 10Mpa pressure pressure.Cut end and post processing such as sides cut after the demoulding (or taking out on the press), artificial slab.

Though each surface of such slab all be a natural wood color with the cross section, " red white " is clearly demarcated, and piebald, flower striped are different, and rich innervation is changeable.Primary colours are red, and the collocation look is the near-white true qualities of little China fir.

Embodiment 2:

Method is basic identical with embodiment 1, has done the change of four aspects: the one, and raw material changes little China fir, sandalwood, three kinds of timber of toon into, and first longitudinal section, back crush-cutting become like the silk wood wool sheet of sheet seemingly again; The 2nd, blend proportion is for respectively accounting for 1/3; The 3rd, batch mixing is with road, back drying process, promptly first drying and impregnation, batch mixing when dry again; The 4th, pressure is 20Mpa.The surface of the slab of making is the piebald white, yellow, that red trichromatism mixes, flower striped look with the cross section, the branch of no primary colours and broken color, and the batch mixing in the present embodiment explanation production stage three process also can carry out in the 4th procedure.

In a word, it is fixed that the ratio that the color and luster collocation in the batch mixing, each grade color and luster account for the slab total amount is appointed, and the appearance of decorative pattern and piebald is at random, causes pattern bright-colored, and is with countless changes.

If needs are arranged, the artificial slab of basis cylindric, oval column or be extended to other column, spherical, the tabular artificial slab of basis again cooperates with mould, can make by this method fully.

This artificial slab is as the side's of being plate body, square body, and then six surfaces and each cross section are square of piebald, flower striped; As be cylinder and oval cylinder, then totally three surfaces and each cross section are piebald, flower stripe surface for cambered surface and end face; Orbicule has only a surface.

Compared to existing technology, the slab density that this method makes is big, the intensity height, without The charing operation, the problem that can not cause wood-fibred to become fragile saves time, energy-conservation, is natural wood The color of fiber and decorative pattern combination, more natural temperament and interest. The slab of making cuts into sheet material Be made into the products such as floor, wallboard, furniture give dynamically like brand-new impression, U.S. Changed the human settlement, and free from environmental pollution when making.
