Abstract

The present invention provides a melamine faced molded fiber board. One layer of melamine impregnated paper is adhibited on the molded fiber board which is already provided with a concave-convex special-shaped surface. The configuration is that the top layer is melamine impregnated paper and the base layer is a double-layer composite structure fiber board which is molded with fiber board substrate. The effect of solid wood simulation is more real and natural. The purpose of high simulation is obtained. The invention also discloses a technique for producing melamine faced molded fiber board and settles the problem that melamine paper can not be adhibited on the board which is already provided with the concave-convex special-shaped surface. The technique of the invention is used for industrialized production.

Description

Melamine facing molding fibreboard and production technology
Technical field:
What the present invention relates to is a kind of novel facing on-plane surface fiberboard, and a kind of melamine facing molding fibreboard and production technology especially are provided, and belongs to the woodwork processing technique field.
Background technology:
Melamine Board is a kind of one-shot forming decorative board, full name melamine dipping film paper face artificial board.Be that the paper that will have different colours or a texture is put into the melamine resin adehsive stick and soaked, be dried to certain state of cure then, it is mated formation on particieboard, medium density fibre board (MDF) or hardboard surface, the decorative panel that forms through hot pressing, make veneer have physical properties such as wear-resisting preferably, anti-stroke, antipollution behind the melamine resin solidification, be used widely in every field such as building, decoration, finishing, furnitures.But because melamine dipping paper is very crisp, frangible after drying, bending and draftability are all very poor, so just are confined to the Melamine Board impregnated paper and can only be used for producing dull and stereotyped, can not paste having concavo-convex heterotype profiled sheet surface decorations.Just form a kind of stable state owing to behind the melamine resin solidification in addition, and hardness is higher, so the finished product Melamine Board can not carry out post forming.Like this, make that the application of melamine veneer products is limited to, exhausted most trimerization oxygen plate all is dull and stereotyped, the Melamine Board that concavo-convex abnormal shape is arranged of small part also is that table is multiple on flat board, extrude the very shallow shape of the not enough 5mm degree of depth then in the heating pressurization, can not carry out the melamine facing on the sheet material that concavo-convex abnormal shape is arranged, third dimension is poor, and product paper grain direction unanimity can not realize that picture is similar to the solid wood simulated effect of anti-solid wood melamine paper veneer products.
Summary of the invention:
The invention provides a kind of melamine facing molding fibreboard, the effect of imitative solid wood is true nature more, has reached high anti-genuine purpose.
The invention also discloses the production technology of melamine facing molding fibreboard, solved melamine can not carry out the melamine facing on the sheet material that concavo-convex Special-Shaped Surface is arranged problem, be used for industrialization production.
Melamine facing molding fibreboard of the present invention is characterized in that:
Have subsides decorations one deck melamine dipping paper on the molded fiber plate of concavo-convex Special-Shaped Surface, constituting its top layer is melamine dipping paper, and bottom is the two-layer composite fiberboard of molded fiber plate substrate.
Melamine facing molding fibreboard production technology of the present invention may further comprise the steps:
1, the molded fiber plate is evenly sprayed 1% ammoniacal liquor+5% timber bleeding agent (MJB-MS), the amount of spraying is 200 ~ 250g/m 2, stack was deposited more than 24 hours, the base material moisture content was controlled at 6 ~ 8% standby;
2, melamine is flooded paper and cut into each parts by the concavo-convex special-shaped size of molded fiber plate;
3, the molded fiber plate surface with step 1 evenly sprays modified urea-formaldehyde resin glue, and spray glue amount is 80 ~ 100g/m 2
4, the melamine dipping paper parts that step 2 cut are multiple to the molded fiber plate according to the corresponding table of pattern texture of concavo-convex Special-Shaped Surface and impregnated paper on the molded fiber plate;
5, will show multiple good molded fiber plate is put back in the same model steel die of producing the molded fiber plate, under 180 ~ 200 ℃ temperature, preheating through 20 ~ 30 seconds, after melamine dipping paper is subjected to thermal softening, be pressurized to 3 ~ 4Mpa, hot pressing release after 30 seconds is flooded paper with melamine and the molded fiber plate is hot pressed into one, form melamine facing molding fibreboard, whole pressing cycle 90 seconds.
Beneficial effect of the present invention: cut according to the special-shaped size of molded fiber plate by melamine being flooded paper, solved that the concavo-convex Special-Shaped Surface melamine dipping of molded fiber plate paper can not stretch and the difficult problem that causes.And utilize melamine dipping paper to be subjected to the characteristics of thermal softening, before pressurization, carry out a period of time preheating earlier, realize the stereo shaping of concavo-convex Special-Shaped Surface, solved melamine can not carry out the melamine facing on the sheet material that concavo-convex Special-Shaped Surface is arranged problem.Through the molded fiber plate of melamine facing, possess all characteristics of Melamine Board, and overlapping part glues together naturally, as such as the melamine product of some imitative solid woods true nature more, reached the high genuine effect of preventing.Further expanded the range of application of melamine veneer products, for the batch production large-scale production pad of a lot of products has been decided the basis.
Description of drawings
Fig. 1 is a melamine facing molding fibreboard structure principle chart of the present invention.
The specific embodiment
Embodiment 1:
