Abstract

The said method includes selection of rare wood grain as templet, grain die cavity prodn with rubber or fibre, laminated pouring and spreading on die cavity based on the structure of composite board, and trimming and painting to obtain grained magnesite composite board. The said method is suitable for producing both planar and non-planar boards and the said wood imitation board may be used in furnature, building, etc.

Description

Grain imitation method and grain magnesite copmosite board

The invention belongs to the imitated method of wood grain, particularly in making the method and the wood grain product thereof of wood grain on magnesite composite board material surface.

Because people like wood furniture, particularly use some famous and precious seeds Hepplewhites, but the unable again purchase of famous and precious seeds valuable product common people, thereby produced the imitated technology of wood grain, on some non-wooden base materials, or general wood surface, add the surface effect of the last layer name grain of wood with technology such as printing, veneer and photomechanical printing.But these methods respectively have outside its deficiency, are easy to peel off foaming as some, the form distortion that has, and the complex process that has, cost is very high, and what have is only limited to the plane, is difficult on the curved surface make etc.

Magnesite composite board material extensive use day by day at present, much be used for utensils such as door-plate, wallboard, cabinet door, shelf, be closely related with people's life, but because their surface color and polish dullness, there is not texture again, be difficult to satisfy the needs on people's sense organ, and still find no the method and the goods of imitated wood grain on magnesite composite board in the prior art.

Purpose of the present invention just is to solve deficiency of the prior art, proposes a kind of method of making wood grain on the magnesite composite board face, and has made the magnesite composite board material of band wood grain.

Wood grain of the present invention is copied method, neither adopts the printing veneer or replica technology, but adopts molding technique, and its key step is followed successively by:

1, mould preparation

A) select the clean mark sheet material conduct attractive in appearance of famous and precious trees to copy model, add frame all around it is lain on the operating platform;

B) be cast on the model of band edge frame with the autovulcanization nature rubber latex, about thick 2-4mm, movable back and forth with scraper plate, drive bubble away;

C) layer overlay glass fabric, the latax that reinjects, after wipeing off gently, spontaneous curing;

D) open gently, just get latex glass wood grain former;

2, the grain magnesite composite plate is made:

A) will be tiled in the latex glass former of wood grain and make on the platform, all around frame in addition;

B) it is reinforced in proper order to press the sandwich construction of magnesite composite board, cast one deck magnesite slip earlier, and the limit is lay glass fabric, filament successively, and the cast slip is continued on the limit, lays up to which floor glass cloth and filament to finish, and pressurizes with conventional method at last;

C) treat curing and demolding, promptly get the magnesite composite board base that has the wood grain skin texture;

3, modify japanning:

A) on the wood grain face of magnesite composite board, modify according to the texture colouring of model;

B) brushing or spraying last layer transparency lacquer on the grain board face that colouring has been modified promptly get goods.

In above-mentioned technical process, also can in the magnesite slip of wood grain face, mix the wooden pigment of model.The material of making the wood grain former also can adopt rubber unsaturated-resin and plastics etc.

By the grain magnesite composite board that above-mentioned wood grain spinning method for genuine is made, not only striped is identical with color and luster and protolignin, and the concave-convex sense with former wood grain skin texture, makes wood grain effect true to nature, and color and luster is identical, can mix the spurious with the genuine completely, and common people are difficult to differentiate.

The imitated method of wood grain of the present invention not only can be used to make the wood grain on magnesite composite board material surface, also can on the material surface of similar moulding by casting, copy wood grain, both can on plane institution movement, copy wood grain, also can on curved surface, make wood grain, because rubber mold can bend to any curve form.

Can make various furniture, decoration element, door panel or panel, windowsill, partition plate, hanging cupboard, kitchen cabinet, dado, skirting board, handrail, shelf etc. by the grain magnesite composite board that the imitated method of wood grain of the present invention is made.

For structure and the application that specifies the grain magnesite composite board, be described in detail with reference to the embodiment of accompanying drawing, its accompanying drawing has:

Fig. 1 is the front elevation of grain magnesite composite board of the present invention;

Fig. 2 is the cutaway view of sheet material shown in Figure 1;

In Fig. 1,2: 10 is the grain magnesite composite board, and 11 is the cover clear varnish, 12 magnesite feed pulp layers for the band wood grain, and 13 is the glass fibre layer of cloth, and 14 is the magnesite feed pulp layer, and 15 is the filament layer.

Embodiment: grain magnesite composite board as shown in Figure 1, 2, it is by 2 layers of glass fabric, the filament layer that 3 layers of magnesite feed pulp layer are clipped in the middle of the glass cloth constitutes, on its positive magnesite feed pulp layer, copy wood grain is arranged, and on wood grain, be covered with layer of transparent varnish, gross thickness is 4mm, and planar dimension is 1200 * 2400mm.

Grain magnesite composite board of the present invention, its planar dimension can be decided according to purposes, the filament layer that is clipped in wherein can be decided according to purposes, its thickness is generally 3-5mm, it is different and thicken also can to look purposes, size, glass fabric is generally layer 2-4, and it also can replace with other fabric or adhesive-bonded fabric.Filament wherein is generally the 1-2 layer.

Imitative wooden magnesite composite board of the present invention can be made the single face grain board by above-mentioned, but also can make two-sided grain board and accompany laminboard layer therein.

Claims
