Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

Referring to fig. 1-3, a compound core, including upper popped paper 1, sandwich layer 3 and lower floor's popped paper 4, upper popped paper 1 complex is at 3 upper surfaces of sandwich layer, the lower floor's popped paper 4 complex is at 3 lower surfaces of sandwich layer, upper popped paper 1 and the 4 center departments of lower floor's popped paper all inlay and are equipped with liquid-permeable layer 6, 3 center departments of sandwich layer inlay and are equipped with imbibition layer 5, 5 outward flanges of imbibition layer are provided with liquid-proof interlayer 2, because popped paper possesses light, it is cheap, the high performance have the tightness low, the planarization is good, characteristics that cuttability is good, make this compound core cost when the preparation lower, and laminating degree is high when using, the travelling comfort is high, and can effectively water conservancy diversion liquid owing to the fluffy nature of popped paper, make things convenient for imbibition layer 5 to carry out liquid absorption, and liquid-proof interlayer 2 can make 5 liquid of imbibition.

The length and the width of the popped paper 4 of upper strata 1, sandwich layer 3 and lower floor are unanimous, and the length and the width that pass through liquid layer 6 are less than the length and the width of imbibition layer 5, and such structure setting makes liquid can get into 5 inside absorptions of imbibition layer completely on passing through liquid layer 6, has promoted this compound core imbibition when using completely.

Example 2

The liquid absorption layer 5 comprises two surface layers 10, a first filling layer 7, a second filling layer 9 and hemispherical covers 8, the surface layers 10 are respectively compounded on the upper surface and the lower surface of the first filling layer 7, the inner walls of the surface layers 10 are provided with the hemispherical covers 8 in a laminating manner, the second filling layer 7 is positioned inside the hemispherical covers 8, the first filling layer 7 is made of wood pulp fibers, the second filling layer 9 is made of water-absorbent resin, the hemispherical covers 8 are of a net-shaped structure, the hemispherical covers 8 are provided with a plurality of hemispherical covers, the distance between every two adjacent hemispherical covers 8 is the same, as the second filling layer 9 is positioned inside the hemispherical covers 8, the second filling layer 9 mainly has the liquid absorption function, and the second filling layer 9 is always positioned inside the hemispherical covers 8 before and after liquid absorption, the volume of the whole core layer 3 can not change before and after liquid absorption, and the phenomenon that the composite core is lumpy is prevented, and because the first filling layer 7 is made of wood pulp fibers, the first filling layer 7 has good air permeability and softness due to loose structure of the wood pulp fibers, and therefore, the air permeability and softness of the whole core layer 3 are higher.

The working principle is that referring to fig. 1-3, the composite core body is formed by compounding an upper layer of bulking paper 1, a core layer 3 and a lower layer of bulking paper 4, because the bulking paper has the characteristics of low tightness, good smoothness and good flow conductivity, the composite core body has high fitting degree, high comfort and convenient liquid absorption when in use, the liquid absorption layer 5 of the composite core body comprises two surface layers 10 and a first filling layer 9 arranged between the two surface layers 10, the filling material is wood pulp fiber, the first filling layer 7 has good air permeability and flexibility because of the loose structure of the wood pulp fiber, the inner wall of the surface layer 10 is provided with a hemispherical cover 8 in a fitting way, the hemispherical cover 8 is of a net structure, the second filling layer 9 is arranged inside the hemispherical cover 8, the filling material is water-absorbent resin, the structure ensures that the second filling layer 9 is always positioned inside the hemispherical cover 8 before and after liquid absorption, make the second filling layer 9 imbibition inflation can not influence the volume change of whole sandwich layer 3, prevented that this composite core body from appearing the phenomenon of sticking together.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
