The utility model is applicable to the package of various large and heavy products, such as an electric product, a motorcycle, a bicycle and the like and is particularly applicable to various heat insulating sites, such as the transportation package of seafood and vegetables.

Description

Shock-resistant heat insulation type corrugated board

Technical field

The utility model relates to a kind of corrugated board, especially relates to a kind of shock-resistant heat insulation type corrugated board.

Background technology

Existing seven layers of corrugated board claim triple wall board again, and by two-layer facial tissue, three layers of corrugation core and two-layer sandwich paper constitute.It is mainly used in the packing case of making the overweight article of transportation.This series products is relatively large as some, the packing of Heavy Product, such as the packing of electronic product, motorcycle, bicycle etc., is mainly used in and substitutes most of coarse, heavy wooden-box package that expends a large amount of timber resources again.But existing seven layers of corrugated board intensity are still not as plank.For making corrugated case obtain necessary strength, take to increase the method for the corrugation number of plies usually, not only increase manufacturing cost, intensity often still is difficult to guarantee Product transport safety.

The utility model content

The purpose of this utility model is to overcome the defective that existing seven layers of corrugated board exist, and provides a kind of shock-absorbing capacity good, shock-resistant, the heat-insulating corrugated board.

The purpose of this utility model is achieved through the following technical solutions:

It comprises outer facial tissue, bottom facial tissue, sandwich paper's I, sandwich paper's II, corrugating media I, corrugating media II, be the corrugating media I between described outer facial tissue and the sandwich paper's I, between bottom facial tissue and the sandwich paper's II is the corrugating media II, it is characterized in that: be the Wood-plastic foam material layer between sandwich paper's I and the sandwich paper's II; Corrugating media I, corrugating media II are identical with the Wood-plastic foam material layer height.

V, U that described corrugating media shape can be GB/T 6544-2008 standard code or the stupefied type of UV, the corrugating media interfacial structure can be the stupefied type of A, B, C, E, F, G, N or O of GB/T 6544-2008 standard code, the shape of corrugating media I and corrugating media II can be identical with structure, also can be different.

Described Wood-plastic foam material can be polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride Wood-plastic foam materials such as (PVC), and foam structure is preferably closed pore, and the aperture is preferably 0.5 ~ 5mm.

Described sandwich paper I and sandwich paper's II can not established, and promptly the one side of corrugating media I and corrugating media II directly is bonded on the Wood-plastic foam material layer.

Described outer facial tissue, bottom facial tissue can adopt brown paper, and corrugating media and sandwich paper can adopt fluting medium.

The used adhesive of bonding between each layer can be the amylan that the traditional tile corrugated paper board is used, and can use the roller gluing.

Described Wood-plastic foam composite is to be raw material with thermoplastics such as polyethylene, polypropylene, polyvinyl chloride and plant fiber powder, through the composite of extruding, forming method such as injection moulding, compacting is made.Because the Wood-plastic foam composite contains the numerous minute bubbles of random distribution, minute bubbles become spheroidal again, and spheroidal has good non-deformability and restorative to external impulsive force, thereby seven layers of more traditional corrugated board of seven layers of corrugated board of the utility model, and shock resistance improves greatly.And the Wood-plastic foam material has that thermal conductivity factor is low, moisture permeability is low, air penetrability is low, can give the heat preservation and insulation of goods excellence.In addition, the Wood-plastic foam material price is cheap, and is therefore, little to the manufacturing cost influence.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Every performance of the corrugated board of each embodiment is tested by GB/T 6544-2008 prescriptive procedure, adopt GB/T 6546-1998 test " determination method of corrugated board side pressure strength " test side pressure strength, adopt GB/T 6545-1998 " determination method of corrugated board pop strength " test pop strength, adopt GB/T 6548-1998 " determination method of corrugated board bonding strength " test bonding strength.

Embodiment 1

With reference to Fig. 1, present embodiment comprises outer facial tissue 1, bottom facial tissue 7, sandwich paper's I 3, sandwich paper's II 5, two-layer corrugating media I 2, corrugating media II 6, be corrugating media I 2 between described outer facial tissue 1 and the sandwich paper's I 3, being corrugating media II 6 between bottom facial tissue 7 and the sandwich paper's II 5, is Wood-plastic foam material layer 4 between sandwich paper's I 3 and the sandwich paper's II 5; Corrugating media I 2, corrugating media II 6 and Wood-plastic foam material layer 4 are highly identical; Corrugating media I 2, corrugating media II 6 shapes are V, U or stupefied types of UV of GB/T 6544-2008 standard code, corrugating media I 2, corrugating media II 6 interfacial structures are stupefied types of A, B, C, E, F, G, N or O of GB/T 6544-2008 standard code, the shape of corrugating media I 2, corrugating media II 6 can be identical with structure, also can be different; Described Wood-plastic foam material layer 4 is PE, PP, PVC or PS Wood-plastic foam material layer, and foam structure is a closed pore, aperture 0.5 ~ 5mm.
