Description

The making method of a kind of Wear resistant decorative plate

Technical field

The present invention relates to the making method of decorative sheet, the making 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 height, shock-proof shatter-resistant, cold-resistant heat-resisting and have fire-resistant protection against the tide and resistance to cigarette to burn characteristic, it 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 fancy fire-proof plate, become the advanced concept building materials taken sb. for a fairy in building circle, it is widely used in the places such as the cabinet of public space, metope, ornament, also becomes Designers and create furniture, the inspiration of jewelry and best materials.

At present, the starting material of Kang Beite are kraft paper, and it is after the kraft paper that soaked by resol by multilayer is dried, then with the coloured paper processed through trimeric cyanamide, be made at high temperature under high pressure, its thickness is determined by kraft paper stacking quantity. But, existing technique needs a large amount of kraft paper, needs first to carry out paper-making process before production, and paper-making process energy consumption height, pollution weigh, and environmental influence is very big, is also the major cause that Kang Beite production cost is high simultaneously. Also had there is not solid wood compound Kang Beite in market in addition, was generally do surface with decorative paper, and color is colder, it does not have solid wood has the characteristics such as pollution-free, decorative pattern nature, elegance should weigh, rich tactile sensation, elasticity are true. Having the wood-based plates such as glued wood plate on market, 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 operates trouble also not scrape 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 making method of a kind of wood surface, high-density, high abrasion, decorative sheet that cost is low.

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

(1) preparation of fiber: after water washed for the plant limb of peeling, chip, boiling, defibrator process make uniform fiber;

(2) applying glue process: first by fiber obtained for step (1) first through drying, then that tackiness agent is even with spray regime and blending in of fibers;

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

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

(5) decorative sheet is suppressed: half-finished upper surface is arranged successively upper epidermis bond paper, wood skin, described half-finished lower surface is arranged wear-resisting bond paper, then makes decorative sheet through thermocompressor hot pressing is shaping.

The preparation of described tackiness agent: get resol 80��90% by weight, auxiliary agent 10��20% mixes and be heated to 50 DEG C and be prepared into tackiness agent; Described auxiliary agent comprises: weight percent 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 and the mass ratio of tackiness agent in described step (2) are 2:3 to 3:2, and spraying pressure is 5-7MPA, and such pressure can be atomized liquid sizing agent, ensure that sizing agent 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 the 15-25 second; Hot pressing temperature is 150-180 DEG C, and pressure is decremented to normal pressure gradually from peak pressure 5MPA, and hot pressing time is the 15-25 second.

In described step (4), described section is cutd open as log is cut into juggle by desired length, then removes the peel and cuts open system wood side again, and plane sheet thickness is 0.5mm; Described boiling is for putting into different boiling pond by wood side respectively by seeds, wood side's specification, and when putting into, water temperature keeps normal temperature, and being then warming up to 50 DEG C of boilings terminates, and heat-up rate is 1 DEG C/min; Wood side after boiling process puts into the storage wood warm water tank insulation before slicing machine in time, and holding temperature is 40-50 DEG C; Described drying be by slicing after wood side put into roller dryer and be dried, dried wood side water ratio is at 8-12%.

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

Described melamine formaldehyde resin liquid comprises: weight percent be 4.5% flexibility agent, the wetting agent of 0.5%, the releasing agent of 0.5%, all the other are melamine resin; The spread of described top layer bond paper and wear-resisting bond paper is 200-300g/m2, fugitive constituent be 6-8%. Spread to be suitable for, and too little wear-resisting not and bonding is not good, the flowing of too big glue uneven 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 sizing agent and fibers carbonization, decrease in strength. Pressure is that 7-9MPA is more suitable, and pressure is too low, density can be caused inadequate, decrease in strength; Otherwise, hypertonia, then easily cause product density too big, the follow-up difficulty processing of product, and equipment injury is also obvious.

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

(1) production cost is low: owing to directly adopting fiber process, eliminates the link making kraft paper, simplifies technique, reduces production cost;

(2) decorative sheet excellent performance: traditional method glue usage quantity is general all within 13%, and glue usage quantity greatly then cannot mix, and common product density is no more than 1.0g/cm3;The present invention adopts spray regime to add tackiness agent can to ensure to mix, and glue usage quantity can reach more than 40%, and product density is at more than 1.45g/cm3; Due to decorative sheet density height, intermediate gaps is filled by sizing agent, and its water tolerance, resistivity against fire, germ resistance, anti-pollution can be better;

(3) energy consumption low emission is few: owing to raw material is bio-waste, and papermaking uses big-diameter wood timber, and papermaking needs to consume a large amount of water, and the water of decorative sheet can recycle; Front section heat when preparing decorative sheet continues to use after can be used for, and whole process energy emission 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 wear resisting property, also can abandon the process of traditional paint coating surface;

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