Abstract

The utility model relates to a clad plate in architectural decoration material field, comprising a surface layer 1 and an interior base plate core layer 2. The clad plate is characterized in that the interior base plate core layer 2 is manufactured through evenly stirring and solidifying magnesium chloride powder, light-burned powder, sawdust or farm crop straw powder, glass fiber, cementing agent and water. The base plate core layer 2 is provided inside with an upper and a lower meshed reinforcing layer 3 and 4. The technology has the characteristics of reasonable structure and design, light mass and high intensity, wide scope of application, capability of sawing, nailing, digging, adhering and the like, fire prevention and flame resistance, non harmful constituents, non-toxic environmental protection, wide raw material source, easy manufacture, low cost and the like.

Description

A kind of composite plate

The utility model relates to technical field of construction and decoration materials, the free of contamination composite plate of particularly a kind of architectural decoration fireproof environmental.

Existing wood-based plate mainly is divided into two big classes, and a class is to utilize the wood-based plate of the wood shavings of various timber for the raw material manufacturing, and raw material sources are limited, and cost is higher; Another kind of is the cane that utilizes crops, is the wood-based plate that raw material is made as the canes of crops such as flax, corn, Chinese sorghum.Above-mentioned two big class wood-based plates no matter, various wood-based plates or the composite plates such as density board, glued board, fiberboard, core-board of being called by people commonly used are decorated in still present building construction, they all exist water imbibition big to some extent, inflammable, intensity is low, the seriously polluted deficiency that waits, and particularly these several plates contain a large amount of harmful substances, as harmful substances such as radioactive element, urine aldehyde, formaldehyde, phenolic aldehyde, directly influence the healthy of people.Though be exactly in addition on the market widely used plasterboard pollution-free, moderate cost, it exists intensity low, service life is short, purposes is single, and deficiencies such as limitation are arranged.

The purpose of this utility model is: develop a kind of reasonable in design, and light weight intensity height, fire-retardant fireproof, asepsis environment-protecting, easily processing, raw material sources are wide, the composite plate of low cost of manufacture.

The utility model is achieved by following manner: a kind of composite plate, comprise surface layer 1 and interior substrate sandwich layer 2 thereof, it is characterized in that: substrate sandwich layer 2 adds adhesive by magnesium chloride powder, light burnt powder, saw foam or crop stalk powder, glass fibre and the water stirring and evenly mixing forms through curing; Uniform upper and lower

netted enhancement Layer

3 and 4 of being provided with about in substrate sandwich layer 2.

Said upper and lower

netted enhancement Layer

3 and 4 adopts the manufacturing of glass fiber cloth material, as shown in Figure 1, 2.

Present technique is to adopt wood residue, saw foam or crop residue, as various crop stalks etc. it is ground into powder, as the filler of making this plate, adopt magnesium chloride powder again, clear water, light burnt powder, adhesive is mixed with pastel, again with above-mentioned any kind of filler input, stir and finally become substrate sandwich layer material, during concrete the manufacturing, on the workbench that sets, evenly throw the shop, at first spread surface layer 1, repave and adorn a laminar substrate sandwich layer material (, and the surface material 1 of bottom not being set) sometimes according to operating position and the laminar substrate sandwich layer material of directly mating formation, and then evenly throw shop netted (drawknot) enhancement Layer 4 as shown in Figure 2 with glass fiber cloth, play the effect that the intersection drawknot is gained in strength, repeat to throw the shop by above technology again, promptly put again and throw shop one laminar substrate sandwich layer material, put one deck glass fiber cloth again, promptly go up netted (drawknot) enhancement Layer 3, and then throw in substrate sandwich layer material, be advisable until reaching required thickness.The thickness degree of every layer of material needs consistent and even when throwing the shop, the thin degree of every layer of glass fabric also need cause evenly, proper time to be cured to, repave and put surface material, as brown paper or microveneer wood skin and other surface material etc., the large press that then enters low-temp low-pressure is suppressed, usually under 50 ℃ of temperature, therefore be bonded into plate, adopt at last mechanized equipment in length and breadth excision forming promptly become finished product.This composite plate can be selected different surface materials for use according to user's different attractive, decorative demands aborning, as paper or different seeds face sides, and the bonding surface that is overlaid on substrate sandwich layer 2, attractive in appearance various, size also can be produced according to user's different demands.Thickness and flexible in size are various.And this composite plate do not have any radioactive element, fire protection flame retarding, and intensity is higher, does not absorb water, and can saw in the use, follows closely, digs, sticking or the like.

The utility model is compared with prior art, has reasonable in design, light weight intensity height, and the scope of application is wide, and can saw, follow closely, dig, glue etc., fire protection flame retarding, no harmful components, asepsis environment-protecting, raw material sources is wide, processing easily, characteristics such as cost is low.

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is a sectional view of the present utility model.

Among the figure: netted (drawknot) enhancement Layer, 4 times netted (drawknot) enhancement Layers on 1 surface layer, the 2 substrate sandwich layers, 3.

Most preferred embodiment of the present utility model, as shown in Figure 1, 2.A kind of composite plate comprises surface layer 1 and interior substrate sandwich layer 2 thereof, it is characterized in that: substrate sandwich layer 2 adds adhesive by magnesium chloride powder, light burnt powder, saw foam or crop stalk powder, glass fibre and the water stirring and evenly mixing forms through curing; Uniform upper and lower

netted enhancement Layer

3 and 4 of being provided with about in substrate sandwich layer 2.

Said upper and lower

netted enhancement Layer

3 and 4 adopts the manufacturing of glass fiber cloth material.
