Polymer compound core body and preparation method thereof

Abstract

The invention discloses a polymer compound core body and a preparation method thereof and relates to a polymer compound core body. The invention provides a polymer compound core body which is mainly used for paper diapers and panty diapers, the polymer compound core body which cam not form lump and can not be broken or delaminated and a preparation method thereof. The compound core body is provided with an airlaid paper surface layer, an airlaid paper bottom layer and a bulking non-woven fabric layer, wherein the bulking non-woven fabric layer is arranged between the airlaid paper surface layer and the airlaid paper bottom layer and is adhered to the airlaid paper surface layer and the airlaid paper bottom layer by an adhesive; and water absorbent resin is uniformly penetrated in the bulking non-woven fabric layer. Urine can be rapidly and completely penetrated to the polymer compound core body; the airlaid paper surface layer of the compound core body can effectively absorb the urine; a polymer water absorbent resin of the polymer compound core body can effectively absorb and store the urine; and the bulking non-woven fabric layer can ensure that the urine rapidly penetrates towards the direction of the bottom layer, thus the water-absorbing quantity is large, the surface layer is kept in a drier state and a human feels comfortable.

Description

technical field [0001] The invention relates to a polymer composite core, in particular to a polymer composite core mainly used in diapers and diapers and a preparation method thereof. Background technique [0002] The polymer composite core has a wide range of uses. At present, the polymer composite core used to absorb and store urine on diapers and diapers has some shortcomings: the structure of the composite core is not reasonable enough, and the polymer of the composite core is selected Inappropriate (small absorption, slow absorption) and uneven distribution (due to equipment performance); the selected bulky non-woven fabric is not suitable, so that the polymer cannot enter, and the diffusion is slow; the surface layer is easy to delaminate, and it is easy to lump during use , Agglomeration, breakage and cause urine to be absorbed in a hurry and lead to side leakage and other shortcomings. [0003] The invention patent application with publication number CN1658810 disc...
