Abstract

The utility model relates to a laminated composite board with films and a directional strong structure, which comprises a base of a directional strong structure plate. The utility model is characterized in that one side of both sides of the base is (are) stuck with at least one layer or more layers of composite boards. The utility model can be selected from single wood boards, films without fiber and /or films with fiber.

Description

Laminated composite board with film and directional strong structure

The utility model relates to a kind of resin covered directional strength structural board, and specifically, it is a kind of covered directional strength structure multilayer composite sheet.

Directional strength structural slab (Orinted Structure Board is called for short OSB) is a kind of novel high-strength wooden structures plate.It is with about 15 centimeter length, 25 centimetres wide, the slicing wood chip of 1 millimeters thick, drying, top sizing and wax, align, scale type layering square crossing mats formation a kind of oriented strand laminate that reshaping hot pressing forms.This is that the glued board layering square crossing veneer of mating formation can be obtained high-intensity principle and is transplanted to the important breakthrough that particieboard is produced, and produces high-intensity improved wood with regard to available low value log (poplar, birch, loose Logs of small diameter) like this.What this plate was brought into use is the wood chip of about 10 centimeter length, the main now wood chip that uses about 15 centimeter length, and its length also has the development trend that prolongs again.Along with the lengthening of wood chip length, the intensity of sheet material also improves constantly, and it is different from particieboard fully and becomes typical high strength laminate material.This is unique structural slab that replaces glued board and solid wood in the wood-base fibre and particle panel material.

The applicant is labelled to the fibre-reinforced resin covered directional strength structural board that few layer of glass fiber fabric impregnated phenolic resin glue is made in the OSB surface gluing that Chinese patent 932254039 has disclosed a kind of above-mentioned surperficial refinement, to improve its surface smoothness, wear resistence and hardness.

The application is in order further to improve the mechanics physical efficiency of synthetic resin, in resin, add reinforcing material, comprising spinning and adhesive-bonded fabric or ultimate fibre of glass fibre, cotton fiber, polyester fiber, asbestos fibre, long fibered paper, diacetate fiber, nylon fiber, Fypro, poly-carbon fiber and wire etc.

The synthetic resin that uses comprises unsaturated polyester resin, epoxy resin, phenolic resins, celluosic resin, amine resin etc. and several composite resin adhesive, as epoxy ten phenolic aldehyde, acetal ten phenolic resins, melamine aminuria formaldehyde copolymerization ten phenolic resins etc.Using above various fortifying fibres to mix the powerful overlay film that manufactures in the various resin glues overlays on the OSB plate with this high-strength membrane, or be attached on the OSB plate with Wooden veneer earlier, paste intensity, rigidity, surface abrasion resistance intensity and anti-the roll ability of glass steel membrane again to strengthen the OSB plate, thereby put forward its fineness and ornamentally develop serial high strength engineering structure plate, comprise building template, container bottom board, the big towed vehicle base plate of automobile and other engineering structure plate and civil building furniture, Decorating Project works etc.This will have huge economic and social benefit.

So, the utility model provides a kind of covered directional strength structure multilayer composite sheet, comprise the substrate of directional strength structural slab, it is characterized in that on the one or both sides sticker of described substrate one deck or MULTILAYER COMPOSITE layer at least, described composite bed can be selected from Wooden veneer, not with the glued membrane of fiber and/or the glued membrane of band fiber.

It is characterized in that described is not a kind of hard section with the glued membrane of fiber.

The glued membrane that it is characterized in that described band fiber is spinning of the place glass fibre, synthetic fibers, natural fiber, asbestos fibre, carbon fiber or the wire fiber that flooded resin or adhesive-bonded fabric is laminated with in described substrate through hot-press solidifying.

What it is characterized in that described substrate pressure sensitive adhesive double coatedly sticks two-layer at least Wooden veneer.

It is characterized in that further being laminated with the glass cloth that one deck at least flooded phenolic resins.

It is characterized in that further being laminated with the carbon cloth that one deck at least flooded resin.

The utility model has the advantages that significantly, it comprises the substrate of directional strength structural slab, and substrate surface is through the refinement preliminary treatment, identical or different composite bed (can be multilayer) on the sticker then, constitute the structural slab of any surface finish, high strength, high rigidity, can be widely used in building, decoration and cement formwork, container bottom board and large-scale towed vehicle base plate.

Physical properties such as strength and stiffness of the present utility model and common OSB plate, overlay film OSB composite plate relatively see Table 1.

Strength and stiffness of the present utility model as can be seen from Table 1 are all above the product of prior art.Especially the bending strength and the surface abrasion resistance intensity of the container bottom board that constitutes with carbon fiber and the two-layer overlay film of glass fibre modification PF, three layers of veneer all are improved largely.

The utility model is described in further detail below with reference to drawings and Examples.
