Description

A kind of preparation method of decorative panel

Technical field

The present invention relates to the preparation method of decorative panel, the preparation method of especially a kind of composite wood Kang Beite.

Background technology

Kang Beite has another name called anti-doubly special, composite wood Kang Beite is through the one-body molded dalle dissolving and irreversible age-hardening produces under HTHP, its sheet material matter stability is high, shock-proof shatter-resistant, cold-resistant heat-resisting and have fire-resistant protection against the tide and resistance to cigarette to burn characteristic, is widely used in the fields such as indoor and outdoor decoration, kitchen cabinet, office furniture, laboratory. Composite wood Kang Beite is as a kind of special high pressure decorative refractory slab, become the leading concept building materials of taking sb. for a fairy in building circle, cabinet, metope, ornament that is widely used in public space etc. located, and also becomes designer and create inspiration and the optimal material of furniture, jewelry.

At present, the raw material of Kang Beite are brown paper, and it is after the brown paper that soaked by phenolic resins by multilayer is dried, then with the coloured paper of processing through melamine, under HTHP, be made, its thickness is determined by the stacked quantity of brown paper. But existing technique needs a large amount of brown paper, needs first to carry out paper-making process before production, paper-making process energy consumption is high, pollution is heavy, very large to ambient influnence, is also the main cause that Kang Beite production cost is high simultaneously. Also there is not the compound Kang Beite of solid wood in market in addition, is generally to do surface with facing paper, and color is colder, the characteristic such as there is no that solid wood has that pollution-free, decorative pattern nature, elegance should weigh, rich tactile sensation, elasticity are true. On market, have the wood-based plates such as solid wood plywood, but these wood-based plates are water-fast not heat-resisting shock-resistant, do not possess health shellfish characteristic energy, protection is painted on surface mostly in addition, so both also scratch-resistant not of troublesome poeration. How to provide a kind of not only simply not only wear-resisting but have health shellfish characteristic can the compound Kang Beite of solid wood, be the technical barrier of this area.

Summary of the invention

The technical problem to be solved in the present invention is to provide the preparation method of a kind of wood surface, high density, high abrasion, decorative panel that cost is low.

For solving the problems of the technologies described above, the preparation method of decorative panel of the present invention, comprises the following steps successively:

(1) preparation of fiber: after the diseases on plant stalk washing of peeling, chip, boiling, defibrator process make uniform fiber;

(2) applying glue processing: the fiber first step (1) being made first, through drying, then mixes with spray regime adhesive with fiber;

(3) precompressed hot pressing: by fiber after treatment applying glue again through mating formation, precompressed, hot pressing make semi-finished product; Precompressed can make fiber at random form one, so that compacting; Hot pressing function is adhesive partial reaction, forms even base substrate, facilitates follow-up use.

(4) wooden skin processing: first log is cut and cutd open, become wood block shape, then soften processing by boiling, then the flitch after softening is carried out to slicing dry, shear forming;

(5) compacting decorative panel: half-finished upper surface is set gradually to upper epidermis bond paper, wooden skin, described half-finished lower surface is arranged to wear-resisting bond paper, then through the hot-forming decorative panel of making of hot press.

The preparation of described adhesive: get by weight phenolic resins 80~90%, auxiliary agent 10~20% mixes and is heated to 50 DEG C and is prepared into adhesive; Described auxiliary agent comprises: the kaolin of the diluent that percentage by weight is 5-20%, the carbon black of 0.5-2% and 2-10%, this diluent is methyl alcohol and/or alcohol.

Fiber in described step (2) and the mass ratio of adhesive are 2:3 to 3:2, and expulsion pressure is 5-7MPA, and pressure energy, the atomization of liquid adhesive, ensures that adhesive fully mixes infiltration with fiber like this.

Precompressed temperature in described step (3) is 30-50 DEG C, and pressure is 2-3.5MPA, and squeeze time is 15-25 second; Hot pressing temperature is 150-180 DEG C, and pressure is decremented to normal pressure gradually from maximum pressure 5MPA, and hot pressing time is 15-25 second.

In described step (4), described section cut open into by log by Len req cutting into lengths, then peeling cut open again flitch processed, flaking thickness is 0.5mm; Described boiling is for to put into respectively different boilings pond by flitch by seeds, flitch specification, and while putting into, the temperature remains within the normal range for water temperature, is then warming up to 50 DEG C of boilings and finishes, and programming rate is 1 DEG C/min; The storage wood warm water tank that boiling flitch after treatment is put into before slicer is in time incubated, and holding temperature is 40-50 DEG C; Described being dried as the flitch after slicing is put into roller drier is dried, and dried flitch moisture content is at 8-12%.

The preparation of described wear-resisting bond paper and top layer bond paper: flood respectively 18g/cm with melamine formaldehyde resin2Overlay paper and 28g/cm2Abrasion-proof paper, after dipping, dry respectively to shear and make top layer bond paper and wear-resisting bond paper.

Described melamine formaldehyde resin liquid comprises: the flexibility agent that percentage by weight is 4.5%, 0.5% wetting agent, 0.5% releasing agent, and all the other are melmac; The spread of described top layer bond paper and wear-resisting bond paper is 200-300g/m2, fugitive constituent is 6-8%. Spread is suitable, and too little wear-resisting not and bond badly, too large solation moves the inhomogeneous marks on surface that causes, and bond paper is not easy to preserve in addition.

Hot pressing temperature in described step (5) is 120-150 DEG C, and pressure is 7-9MPA, and hot pressing time is 80-100 minute. Hot pressing temperature be 120-150 DEG C more suitable, temperature is too low, can cause solidifying not exclusively, not water-fast; Otherwise excess Temperature, easily causes adhesive and fiber carbonization, intensity declines. Pressure is that 7-9MPA is more suitable, and pressure is too low, can cause density inadequate, and intensity declines; Otherwise hypertonia, easily causes product density too large, the follow-up difficult processing of product, also obvious to equipment injury.

The technique effect that the preparation method of decorative panel of the present invention compared with prior art has:

(1) production cost is low: owing to directly adopting fiber process, saved the link of making brown paper, simplified technique, reduced production cost;

(2) decorative panel excellent performance: conventional method glue use amount is generally all in 13%, and glue use amount greatly cannot mix, and common product density is no more than 1.0g/cm3; The present invention adopts spray regime to add adhesive can ensure to mix, and glue use amount can reach more than 40%, and product density is more than 1.45g/cm3; Because decorative panel density is high, intermediate gaps is filled by adhesive, and its resistance to water, fire resistance, antibiotic property, anti-pollution can be better;

(3) energy consumption low emission is few: because raw material is bio-waste, be large footpath timber material and papermaking is used, papermaking need to consume large water gaging, and the water of decorative panel can recycle; Leading portion heat while preparing decorative panel can use for continuing below, and whole Process Energy discharge is few;

(4) solid wood and Kang Beite integrally combine, and the warm sense of existing solid wood, has again Kang Beite characteristic property;

(5) adopt abrasion-proof paper surface, neither affect timber effect, have again superpower scratch resistance anti-wear performance, also can abandon the processing of traditional paint coating surface;

(6) tightly connected wood skin and the core of impregnation overlay paper of large glue amount, structure is more firm.
