Description

A kind of compound corrugated sheet

Technical field

The utility model relates to corrugated sheet technical fields, particularly relate to a kind of compound corrugated sheet.

Background technique

Corrugated sheet is also referred to as contour plate, using sheet metals such as color painted steel strip, galvanized sheets through roll-in clod wash at various The contour plate of wave mode, it is suitable for industry and civil buildings, warehouse, extraordinary building, the roofing in large-span steel house, metope And decorating inner and external walls etc..With light, high-strength, color is abundant, convenient and quick construction, antidetonation, fire prevention, rain-proof, the service life is long, exempts from The features such as maintenance, by wide popularization and application.

The bonding of existing panel and corrugation core plate is completed by viscose, and the adhesive surface of corrugation core plate is close with panel Viscose is easy to be squeezed to two sides and overflow after fitting, be easy to cause leak adhesive and causes bonding unstable；The resistance of existing corrugated sheet The effect is unsatisfactory for combustion, can not cope with the various forms of fire behaviors that may occur；Traditional corrugated board also have easy aging, The problems such as deformation, overlay paper falls off, its quality and service life are reduced, in order to ensure the application with further expansion corrugated board Range improves quality and prolongs the service life, and people pay attention to the external protection of corrugated board further.

Utility model content

It is easy to process the utility model discloses a kind of compound corrugated sheet, manufactured composite corrugated board have intensity it is high, The advantages that elasticity is good, be unlikely to deform, prevent fires, rain-proof, long service life.

The utility model is achieved through the following technical solutions:

A kind of compound corrugated sheet, including plastic film layers, flame-retardant layer, corrugation core plate, the corrugation core plate have two layers, institute It states and is equipped with two layers of stiffening plate between corrugation core plate, the stiffening plate is close to corrugation core plate respectively, is additionally provided between the stiffening plate One layer of elastic layer, the corrugation core plate outside are equipped with one layer of flame-retardant layer, and the flame-retardant layer of the top also wraps up one layer of plastics Film layer.

Preferably, the corrugation core plate extends in undaform, and the corrugation core plate is with flame-retardant layer and the stiffening plate place of abutting Adhesive surface, the adhesive surface are equipped with equally distributed several grooves, are equipped with viscose in the groove.

Preferably, the depth of the groove is less than or equal to 1.5mm.

Preferably, the flame-retardant layer is coated using melamine flame retardants.

Preferably, the stiffening plate uses high-strength rigid cardboard.

Compared with prior art, the utility model has the beneficial effects that

1, the utility model increases groove structure on the adhesive surface of corrugation core plate, in corrugation core plate and flame-retardant layer and adds Groove can accommodate viscose when the fitting of plate by force, avoid bonding caused by leak adhesive unstable, and groove structure has by force corrugation core plate Change effect, promotes its intensity further；

2, it is equipped with flame-retardant layer on the outside of two layers of corrugation core plate of the utility model, strengthens the general flame-retardant for meeting corrugated sheet Effect improves the ability for coping with different fire behaviors；

3, roll-in is made together for the plastic film layers of the utility model, flame-retardant layer, corrugation core plate, stiffening plate and elastic layer, Easy to process, manufactured composite corrugated board has many advantages, such as that intensity is high, elasticity is good, is unlikely to deform, prevents fires, rain-proof, service life are long.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of the utility model corrugation core plate.

In figure: 1, plastic film layers；2, flame-retardant layer；3, corrugation core plate；4, stiffening plate；5, elastic layer；6, groove；7, it bonds Face.

Specific embodiment

The present invention will be further described with reference to the accompanying drawing:

A kind of compound corrugated sheet, including plastic film layers 1, flame-retardant layer 2, corrugation core plate 3, the corrugation core plate 3 have two Layer, two layers of stiffening plate 4 is equipped between the corrugation core plate 3, the stiffening plate 4 is close to corrugation core plate 3, the stiffening plate 4 respectively Between be additionally provided with one layer of elastic layer 5, one layer of flame-retardant layer 2, the flame-retardant layer 2 of the top are equipped on the outside of the corrugation core plate 3 Also wrap up layer of plastic film layer 1.

The corrugation core plate 3 extends in undaform, and the corrugation core plate 3 is bonding with flame-retardant layer 2 and 4 place of abutting of stiffening plate Face 7, the adhesive surface 7 are equipped with equally distributed several grooves 6, are equipped with viscose in the groove 6.

The depth of the groove 6 is less than or equal to 1.5mm.

The flame-retardant layer 2 is coated using melamine flame retardants.

The stiffening plate 3 uses high-strength rigid cardboard.

The utility model increases groove structure on the adhesive surface of corrugation core plate, in corrugation core plate and flame-retardant layer and reinforcement Groove can accommodate viscose when the fitting of plate, avoid bonding caused by leak adhesive unstable, and groove structure has reinforcing to corrugation core plate Effect, promotes its intensity further；It is equipped with flame-retardant layer on the outside of two layers of corrugation core plate of the utility model, strengthens and meets watt The general flame-retardant effect of stupefied plate improves the ability for coping with different fire behaviors；The plastic film layers of the utility model, flame-retardant layer, watt Roll-in is made together for stupefied core plate, stiffening plate and elastic layer, easy to process, manufactured composite corrugated board is high with intensity, elasticity is good, Be unlikely to deform, prevent fires, rain-proof, long service life the advantages that.

The above only expresses the embodiments of the present invention, and the description thereof is more specific and detailed, but can not be because This and be interpreted as that a limitation on the scope of the patent of the present invention, within the spirit and principle of the utility model, made What modification, equivalent replacement, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent Shield range should be determined by the appended claims.
