Description
Technical field
The invention belongs to water-absorbent material technical fields, and in particular to a kind of using stalk as the system of the composite absorbent material of base material
Preparation Method.
Background technology
High hydroscopic resin (Superabsorbent Polymers abbreviation SAP) refers to that can be inhaled rapidly by aquation
It receives the liquid water of tens times or even thousands of times of sole mass and is in gel, and a kind of lightly crosslinked macromolecule of good water-retaining property
Polymer is a kind of novel chemical preparation to grow up in recent ten years.Common water-retaining agent has two kinds of solid-state and liquid, Gu
State has three kinds of powder, thin slice and threadiness again, with powdered most widely used.Since most of it is poly- by lower-molecular substance warp
It closes the high polymer of reaction synthesis or is made through chemical reaction of high-molecular compound, referred to as high water absorbent（Lin Runxiong, Huang Yu
Gift, Lv Yijun, 1998）.It has the performance for inhaling water storage point, it can absorb rapidly and keep reaching own wt hundred times so that on
Thousand times of water.Gel is generated after water swelling, moisture is not easy to isolate.The water absorbing properties of water-retaining agent and its form, shape, grain size are big
It is small related.Not only water absorbing capacity is strong for high absorbency material, and water holding capacity is very high, and big pressure no matter is added after water suction also not
Dehydration, therefore it is called high-moisture-retention material.
In medical and hygiene article field, people using the characteristics such as the absorption urine of super absorbent resin, blood, drug as
Absorbing material, such as sanitary napkin, diaper, napkin paper, incontinence piece, medical absorbent cotton.The super-strong moisture absorbing ability of super absorbent resin and
Water holding capacity make physiological hygiene in terms of product significantly lighting, miniaturization, comfortableization, to eliminate people much worried.
Make hygienic material with super absorbent resin and become basically universal in the countries and regions such as the U.S., Japan, Europe.In addition, high suction in recent years
Application of the water-base resin in medical slow release technology also results in the attention of people.Using super absorbent resin as medicine
Releasable material most benefit is can to reach control drug by adjusting its structure with appropriate biological body feature and moisture content and release
The speed put.
But high hydroscopic resin is easy to generate pollution to environment there is manufacturing cost height, it can be right when being in direct contact skin
Skin generates stimulation, limits its scope of application.Therefore, it is necessary to make improvements otherwise.
