The invention belongs to absorbent material field, be specifically related to a kind of high-intensity water absorbent acrylate foamed materials and preparation thereof
Methods and applications.
Background technology
Present hygienic article, the absorbent material of the inside mainly has granular synthetic resin, absorbs water, inhales urine or inhale
Gel can be formed after blood, the most agglomerating, cause more difficult being fixed on a position, actually used during make us very uncomfortable.
Therefore the flexible absorbent material developing bulk has great significance.
Common blood is made up of hemocyte, blood plasma etc..A diameter of about 8 m of hemocyte, and acrylic molecules
Diameter much smaller than the diameter of hemocyte.Therefore hemocyte is difficult to be absorbed by gelatinous super absorbent resin, can only stop
On the surface of super absorbent resin, the composition such as the blood plasma in the simply blood of absorption.So exploitation porous type polymer, to expand
Specific surface area, improves permeability, the aspect such as the infiltration rate of accelerating liquid and absorbance have important technical economic benefit and
Social benefit.
For acrylate foamed materials in the market, although existing document report has been prepared to have and inhaled faster
Receive the foamed materials of liquid velocity, but owing to its tensile property is not enough, the stretching therefore increasing acrylate foamed materials is strong
Degree has important practical significance.
