Abstract

The present invention provides an absorption product, which comprises an absorption core body 1. The absorption core body 1 comprises: an upper permeable layer and a lower permeable layer, and the upper permeable layer and the lower permeable layer have an integrated polymer microporous foam structure, wherein a plurality of first permeable holes are provided in the upper permeable layer, a plurality of second permeable holes are provided in the lower permeable layer, and the aperture of the first permeable holes is larger than that of the second permeable holes. A hydrophilic surface layer 2 is provided on the upper surface of the absorption core body 1, and a water-repellent bottom layer 3 is provided on the lower surface thereof. The absorption core body 1 is obtained by reacting an acrylate monomer, modified acrylate, a cross-linking agent, a photoinitiator, an emulsifier and an initiator, wherein the modified acrylate is obtained by reacting the reaction product of isosorbide and glycidyl ether with acrylic acid. The present invention solves the problems of slow liquid absorption, side leakage and being prone to back seepage due to the accumulation of menstrual blood on the surface of the absorption core body; and has good application prospects.
