Description

A kind of preparation method of high-density decorative plate

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 at high temperature under high pressure through the one-body molded dalle dissolved and irreversible age hardening produces, 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, be 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 advanced concept building materials taken sb. for a fairy in building circle, be widely used in the places such as the cabinet of public space, metope, ornament, also become designer and create furniture, the inspiration of jewelry and optimal material.

At present, the raw material of Kang Beite are kraft, and it is after the kraft soaked by phenolic resins by multilayer is dried, then with the coloured paper through melamine process, be made at high temperature under high pressure, its thickness is determined by the stacked quantity of kraft.But existing technique needs a large amount of kraft, need 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 cost of production is high simultaneously.Also there is not solid wood compound Kang Beite in market in addition, is generally to do surface with facing paper, and color is colder, do not have solid wood to have the characteristics such as pollution-free, decorative pattern natural, elegance should weigh, rich tactile sensation, elasticity are true.There are the wood-based plates such as solid wood plywood in market, but these wood-based plates are water-fast not heat-resisting shock-resistant, do not possess health shellfish characteristic energy, protection is painted mostly in surface in addition, so both troublesome poeration also not scratch-resistant.How to provide a kind of not only simply not only wear-resisting but have health shellfish characteristic can solid wood compound Kang Beite, 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 water washed for the diseases on plant stalk of peeling, chip, boiling, defibrator process make uniform fiber;

(2) applying glue process: first by fiber obtained for step (1) first through drying, then by bonding adhesive with spray regime and fibers mixture even;

(3) precompressed hot pressing: by the fiber after applying glue process again through mating formation, precompressed, hot pressing makes semiproduct; Precompressed can make processbearing astrocyte at random one, to suppress; Hot pressing function is adhesive partial reaction, forms even base substrate, facilitates follow-up use.

(4) wooden skin process: first carry out cutting to log and cut open, become wood block shape, then carry out sofening treatment by boiling, then carries out slicing and dry, shear forming by the flitch after softening;

(5) suppress decorative panel: half-finished upper surface is set gradually upper epidermis bond paper, wooden skin, described half-finished soffit is arranged wear-resisting bond paper, then make decorative panel through hot press is hot-forming.

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

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

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 remove the peel and cut open flitch processed again, flaking thickness is 0.5mm; Described boiling is for put into different boiling pond by flitch respectively by seeds, flitch specification, and when putting into, the temperature remains within the normal range for water temperature, and be then warming up to 50 DEG C of boilings and terminate, programming rate is 1 DEG C/min; Storage wood warm water tank before flitch after boiling process puts into slicer is in time incubated, and holding temperature is 40-50 DEG C; Described drying is the flitch after slicing is put into roller drier carry out drying, and dried flitch moisture content is at 8-12%.

The preparation of described wear-resisting bond paper and top layer bond paper: flood 18g/cm respectively with melamine formaldehyde resin 2overlay paper and 28g/cm 2abrasion-proof paper, dry shearing after dipping respectively and make top layer bond paper and wear-resisting bond paper.

Described melamine formaldehyde resin liquid comprises: percentage by weight is flexibility agent, the wetting agent of 0.5%, the release agent of 0.5% of 4.5%, and all the other are melmac; The spread of described top layer bond paper and wear-resisting bond paper is 200-300g/m 2, fugitive constituent is 6-8%.Spread will be suitable for, too little wear-resisting not and bond bad, and too large solation moves and unevenly causes marks on surface, 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 solidification not exclusively, not water-fast; Otherwise temperature is too high, then easily cause adhesive and fibers carbonization, intensity declines.Pressure is that 7-9MPA is more suitable, and pressure is too low, and density can be caused inadequate, and intensity declines; Otherwise hypertonia, then easily cause product density too large, the follow-up difficulty 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) cost of production is low: owing to directly adopting fiber process, eliminates the link making kraft, simplifies technique, reduces cost of production;

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

(3) energy consumption low emission is few: because raw material is bio-waste, and papermaking uses big-diameter wood timber, and papermaking needs to consume large water gaging, and the water of decorative panel can recycle; Continue after leading portion heat when preparing decorative panel can be used for use, 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 wood effect, have again superpower scratch resistance anti-wear performance, also can abandon the process of traditional paint coating surface;

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