Abstract
The invention discloses a high-breathability water absorbable acrylic ester foamed material as well as a preparation method and an application thereof. The prepared high-breathability water absorbable acrylic ester foamed material has strong toughness, and good breathability; the obtained foamed material is small in cell size, average deionized water absorption rate, average saline water absorption rate, average artificial urine absorption rate and average artificial blood absorption rate of the obtained foamed material are respectively higher than 15g/g, and water retention rate in half hour is more than 80%, so that the high-breathability water absorbable acrylic ester foamed material is applicable to dispersion and storage of water containing fluid; meanwhile, nano calcium carbonate is added, so that production cost is obviously reduced, and the high-breathability water absorbable acrylic ester foamed material is applicable to mass production; a block flexible water absorbing material in the invention is suitable for application in the field of health products.
Description
Technical field
The invention belongs to water-absorbing material field, be specifically related to a kind of highly air-permeable water suction acrylate foam materials and its preparation method and application.
Background technology
Present sanitary product, the water-absorbing material of the inside is mainly to have granular synthetic resins, water suction, inhale urine or suck blood after can form gel, easily agglomerating, cause the more difficult position that is fixed on, in actual use procedure, make us very uncomfortable.Therefore developing block soft water-absorbing material has great significance.
Common blood is comprised of hemocyte, blood plasma etc.The diameter of hemocyte is 8 μ m left and right, and the diameter of acrylic molecules is much smaller than the diameter of hemocyte.Therefore hemocyte is difficult for being absorbed by gelatinous super absorbent resin, can only rest on the surface of super absorbent resin, the compositions such as blood plasma in the just blood of absorption.So exploitation multi-hole type polymkeric substance, to expand specific surface area, improves perviousness, the aspects such as the absorption rate of accelerating liquid and specific absorption have important technical economic benefit and social benefit.
For the foam materials that adopts acrylic ester monomer to prepare, in prior art, be to improve the processing characteristics of goods with more expensive stopping composition or auxiliary agents of many interpolations such as dimensional stabilitys, this has caused production cost too high on the one hand, is not suitable for scale operation; On the other hand, the most permeability of the acrylate foam materials prepared in prior art are poor, are not suitable for being applied in hygiene article sector, and this has limited the application of acrylate foam materials in Shangdi largely.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of preparation method of highly air-permeable water suction acrylate foam materials is provided; Acrylate foam materials prepared by the present invention has higher water-intake rate and water retention property preferably, and permeability is excellent simultaneously, and production cost is low, has greatly widened the range of application of acrylate foam materials.
Another object of the present invention is to provide the highly air-permeable water suction acrylate foam materials being prepared by preparation method of the present invention.
Another object of the present invention is to provide the application of described highly air-permeable water suction acrylate foam materials in sanitary product.
Above-mentioned purpose of the present invention is achieved by following technical solution:
The preparation method of highly air-permeable water suction acrylate foam materials, comprises the steps:
