Abstract

The utility model relates to a panel which is composed of surface reinforced layers (1), (3) and a middle structure layer (2). The utility model is characterized in that the middle structure layer (2) is composed of natural mineral powder, natural lightweight plant powder and an adhesive which is made of natural mineral materials; the two surface reinforced layers (1), (3) are both composed of glass fiber grid cloth and the adhesive which is made of the natural mineral materials; the surface reinforced layers (1), (3) are shaped by pressing in one process in a mould through a board press. Therefore, the utility model has the advantages of good integral structure, no deformation, fire prevention, damp prevention, moth prevention, light weight, good elasticity, convenient transportation, not easy break and low cost. The utility model has the best advantage that the panel has no toxicity and side effects; because the quantity of formaldehyde emission and the index of activity are both better than national standards, the utility model is the environmental protection building material. The utility model can be used for nailing, shaving and sawing, facings are pasted on the surface of the utility model, paints are brushed on the surface of the utility model, the utility model can replace wood to manufacture various kinds of furniture, and the utility model can also be used as the panel to make various decorations, fitments and a partition wall.

Description

A kind of sheet material

[technical field]

The utility model relates to a kind of sheet material, belongs to building materials field.

[background technology]

Sheet material kind on the market is varied, inorganic, organic at present has, and novel sheet material mainly contains U.S. splice, calcium silicate plate is cement fibrolite plate, plasterboard.U.S. splice is a kind of sheet material of every better performances in the present fire-proof board, but its hold gong nail power and panel density relatively poor, thereby make its purposes limited, particularly can not make furniture; Calcium silicate plate is a cement fibrolite plate because of silicon acid plumping coefficient and water absorption rate are all high, and water absorption rate is 30%, and sheet material is firm, poor flexibility, construction are not convenient, must specific purpose tool, be difficult to the secondary construction, and than great, the carrying effort, breakage rate is big, and fracture is not water-fast easily; The plasterboard suction is big, easy dilatancy, and weight is big, and carrying is inconvenient, surface applying power is poor, can't paste ceramic tile and other decorative layer, and plate body rigidity is big, can't moulding, not water-fast, be afraid of moistly, be immersed in that every performance obviously descends in the water, can't do wet type light cement grouting works.

[summary of the invention]

For overcoming the above-mentioned defective of existing sheet material, the utility model provides a kind of purposes wide, energy fire prevention, waterproof, mothproof, good processability, in light weight, good springiness, burst size of methanal and radioactive indicator all are lower than the board of national standard, to save timber resources, satisfy people to the requirement of plate at price, safety, aspect such as easy to use.

For solving its technical problem, the technical solution adopted in the utility model is: design a kind of by mineral powder and light filler as the structure sheaf that Paris white, flyash, wood powder, crushed crude pearlite, haydite powder and adhesive are formed, be provided with the enhancement Layer of forming by glass fiber mesh and adhesive on the two sides of structure sheaf, by the disposable extrusion forming of trigger squeeze.

The beneficial effects of the utility model are: 1. because the raw material of the utility model sheet material all adopt natural mineral powder, flyash, wood powder, rice husk powder, magnesium chloride, be a spot of plasticizer only, therefore this sheet material can prevent fires, protection against the tide, good stability, indeformable, its linear expansion coefficient is smaller or equal to 0.64 after testing, its burst size of methanal is extremely low, only is 0.74～2.15mg/100g, and radioactivity requires to reach national A level, be Ira=0.09, I _Y=0.05, these two indexs all reach national requirements for environmental protection.

2. the raw material of this sheet material is wide, and production technology is simple, so its price is low.

3. the light material that adopts because of inserts, therefore institute's panel weight of making is light, good springiness, easy fracture not, convenient in carrying, breakage rate can dig, follows closely, bores, cuts out, pastes, twist carpenter's processing such as screw as wooden boards, also can arrange in pairs or groups various panels, decorate skin and carry out secondary operations, as pasting ceramic tile, wallpaper, brush paint, so purposes is wide, can make decoration, the finishing of various occasions or make to cut off sheet material, also be fit to make furniture.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1 enhancement layer, 2 structure sheafs, 3 enhancement layers.

[specific embodiment]

Participate in accompanying drawing: on the die bottom plate of sheet material, with mix up in advance by magnesia, potassium permanganate, the mat formation enhancement layer (1) of a face of adhesive that mineral materials such as alum are made and fiberglass gridding cloth, the one deck of on enhancement layer, mating formation again mix up in advance by crushed crude pearlite, mineral materials such as flyash and by wood powder, husk, the structure sheaf (2) that the light natural material of plant stalk powder etc. and adhesive are formed, the enhancement layer (3) that the one deck of mating formation on structure sheaf again is made up of adhesive and fiberglass gridding cloth, disposal pressed moulding in trigger squeeze then, through solidifying, the demoulding, maintenance, after the detection, promptly become an anticipatory remark utility model sheet material.

Claims

1, a kind of sheet material, it is characterized in that: the structure sheaf (2) of the centre of sheet material for being modulated into by mineral powder, light natural vegetable material and adhesive is respectively equipped with enhancement layer (1) and the enhancement layer of being made up of adhesive and glass fiber mesh (3) on the two sides of structure sheaf.

2, sheet material according to claim 1 is characterized in that: described mineral powder is crushed crude pearlite, flyash, and described light natural vegetable material is wood powder, husk, plant stalk powder.
