Absorbent is difficult to there is preferable absorbent properties under various circumstances.On the other hand, the big absorbability of the liquid absorption amounts such as diaper
In product, macromolecule dosage is larger, and can expand rapidly after the absorption of macromolecule water uptake layer, causes gel blockage, seriously affects two
Secondary infiltration rate leads to the dry-ness decline in surface layer.
Summary of the invention
In view of this, the present invention is directed to propose a kind of absorbing products composite absorbent paper and preparation method thereof, to overcome
The absorbability of the deficiencies in the prior art, composite absorbent paper is good, and not will cause gel blockage after absorbing water, while preparation process letter
It is single, it is at low cost.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of absorbing products composite absorbent paper, including upper separation layer, lower separation layer and be located at the upper separation layer and
Water absorption layer between the lower separation layer, the water absorption layer include on breadth direction spaced first water absorbing agent constitute
The second water absorption layer composition that first water absorption layer and the second water absorbing agent are constituted.
The upper separation layer refers to applied in absorbing products, the face towards user's skin；The lower isolation
Layer refers to the face applied in absorbing products, far from user's skin, further, the upper separation layer and the lower isolation
Layer can be non-woven fabrics, dust-free paper or wet-strength paper, the upper separation layer, the lower separation layer and the water absorption layer by glued or
Heat seal mode is combined together.
Further, first water absorption layer and the second water absorption layer width are equal.
Further, the water absorption layer further includes diversion trench, and the water conservancy diversion groove depth is equal to water absorption layer thickness, the water conservancy diversion
Slot position is between first water absorption layer and the second water absorption layer or is located in first water absorption layer or absorbs water positioned at described second
Layer.
It further, further include high fluffy nonwoven layer, the fluffy nonwoven of height between the upper separation layer and lower separation layer
Water absorption layer is divided into upper water absorption layer and lower water absorption layer by layer of cloth on composite absorbent paper thickness direction.
Further, the upper water absorption layer and the first water absorption layer in lower water absorption layer and the second water absorption layer position are mutually right
It answers.
Further, first water absorbing agent and second water absorbing agent refer both to commercially available hydroscopic high-molecular resin, described
The difference of first water absorbing agent and second water absorbing agent, first polymer water-absorbent and the second polymer water-absorbent performance
Difference, this difference can express in many aspects, be mainly manifested in particle diameter distribution, absorption using technical characteristic difference as this
Amount, moisture-holding capacity and pressurizing absorption amount, infiltration rate, gel lead to fluidity energy, the even many aspects such as cost, those skilled in the art
Can properties of product specification by self testing or when passing through purchase obtain above-mentioned variance data.
For the present invention, it is only important that including that first and second be spaced apart inhale on blotting paper breadth direction
Aqua, rather than single water absorbing agent.To form the absorbed layer with particular characteristic in the specific region of blotting paper, and another
Region forms another absorbed layer with otherness.And the absorbed layer of this differentiation can exist simultaneously on breadth direction.
It is of the invention for ease of understanding, a kind of unrestricted example, the first absorbent uptake of blotting paper middle section is big, water conservation
Ability is strong, and the second absorbent infiltration rate positioned at its two sides is fast, and uptake is relatively small.
Another unrestricted example is effectively distribution fluid not for the water absorption layer being made of multi-layer absorbent agent
The uptake of same layer, due to being made of in single layer water absorption agent spaced two kinds of water absorbing agents, so that point of the fluid in blotting paper
With with better controllability, preferably to realize this controllability, the combination of the first water absorbing agent of upper layer and the second water absorbing agent with
The first water absorbing agent of lower layer and the combination of the second water absorbing agent are different.Such as centre region is slow by absorption speed in the upper layer, diffusivity of pressurizeing
Can well or logical fluidity can good the first water absorbing agent constitute, two sides are very fast by absorption speed, pressurization diffusion is good or logical fluidity energy
The second good water absorbing agent is constituted, and lower layer's middle section by infiltration rate the first good water absorbing agent group of slow, water retainability, logical fluidity
At by infiltration rate, the second good water absorbing agent of very fast, water retainability, logical fluidity energy is constituted for two sides.
It is upwardly formed the absorption region of two species diversity in breadth side, it is this for those skilled in the art to exist simultaneously this
The beneficial effect of species diversity absorbed layer it is clear that the faster water absorption layer of infiltration rate after absorbing water can rapid expanding, and inhale
The slower water absorption layer speed of expansion of water speed is slower, in this way, after absorbing water, since two water absorption layers are alternatively arranged, having in this way
One column expand larger and another column and expand lesser phenomenon appearance, can all expand to avoid entire water absorption layer, on the one hand drop
The influence of low water absorption layer gel blockage forms the groove longitudinally extended along blotting paper on the other hand due to the difference of swelling volume,
Diversion channel slot is formed in multiple absorb, is conducive to longitudinal diffusion, high molecular utilization rate is promoted, to promote the dry and comfortable of surface
Property.Simultaneously because middle section absorbed layer water holding capacity is stronger, surface dry is further promoted.

To expand the screening range of the first water absorbing agent and the second water absorbing agent.Since high molecular particle diameter distribution is to high molecular washing lotion speed
Degree, liquid-keeping property, pressurization and have large effect for the quantitative control of composite absorbent paper at imbibition ability, are sieved by partial size
Point, the macromolecule of particle size distribution range Relatively centralized is obtained, to expand the performance difference of the first water absorbing agent and the second water absorbing agent.When
Screening is based on extensive commercially available macromolecule expansion, by the range of choice of further expansion the first water absorbing agent and the second water absorbing agent.Together
When the screening based on partial size, greater concentration of first water absorbing agent of particle diameter distribution and the second water absorbing agent are obtained, for quantitative control, matter
The stability of amount, the further beneficial effects such as the macromolecule distribution gradient of improvement on blotting paper thickness direction.
The present invention provides a kind of non-limiting example, for obtain composite absorbent paper performance bigger improvement, Sieving and casing
It selects most important for the improvement of performance.It is right due to the difference of different, the selected raw material for composite absorbent paper performance requirement
It is selected in Sieving and casing, has biggish difference.But some important factors in need of consideration include macromolecule particle diameter distribution, no
With partial size macromolecule needed for high fluffy non-woven fabrics transmitance, the polymeric absorbent performance indicator of different-grain diameter, composite absorbent paper
The factors such as absorption characteristic, composite absorbent paper macromolecule quantitative requirement.Height in the present invention, in the upper hydroscopic high-molecular resin layer
Molecule water-absorbing resin partial size is greater than the partial size of hydroscopic high-molecular resin in the lower hydroscopic high-molecular resin layer, the upper macromolecule
Hydroscopic high-molecular resin partial size in water-absorbing resin layer is 20~40 mesh, macromolecule water uptake in the lower hydroscopic high-molecular resin layer
The partial size of resin is 40~80 mesh.Since upper layer macromolecule partial size is larger, gel strength is good, water holding capacity all gets a promotion, into
One step reduces reverse osmosis, improves the dry and comfortable degree of absorbent article.Since lower hydroscopic high-molecular resin layer partial size is relatively thin, high fluffy nothing
Woven fabric can accommodate more macromolecules, so as to improve the distribution of lower hydroscopic high-molecular resin layer.Gel can be reduced
The influence of retardance.Meanwhile under conditions of not changing blotting paper breadth, so that the promotion of composite absorbent paper uptake, to make
Macromolecule layer forms different purpose absorbed layers and is possibly realized above and below obtaining, and lower layer is as main Fluid Storage Layer, upper layer as anti-
Reverse osmosis, lifting fluid lead to fluidity, promote lower layer's utilization rate.Due to the formation of the absorbed layer of different purposes, also entirely to manufacture
Journey brings improvement, due to the variation of lower hydroscopic high-molecular resin layer effect, declines in whole macromolecule specific gravity, to drop
Low upper layer resin added reduces cost and excessive the resin added adverse effect caused by absorbent properties.Lower hydroscopic high-molecular resin
The improvement of layer partial size can be more distributed into high fluffy non-woven fabrics, to significantly improve lower separation layer and the fluffy non-woven fabrics of height is fluffy
The adhesive strength of loose side reduces manufacture difficulty, while also significantly improving composite absorbent paper macromolecule and falling off bring absorbability
The loss of energy.For macromolecule based on same marque, by the difference of improved particle diameter distribution, absorbent properties tool is obtained
The macromolecule that there were significant differences.The difference of this performance can be used in the absorption characteristic for improving composite absorbent core.Certainly, it is based on
Particle diameter distribution obtains the improvement of high molecular chemical characters, and by extending to the macromolecule of different model, can further enhance this has
