Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of water-retaining agent.
Background technology
In recent years, about sanitary material such as disposable diaper and sanitary towel, its height is functionalized to make progress with slimming, increase the water-absorbing resin amount of using in every a slice sanitary material so exist, and water-absorbing resin is with respect to the trend of the mass percent of the whole absorbing structure that is comprised of for example water-absorbing resin and hydrophilic fibre.Particularly, the consumption by reducing hydrophilic fibre (it has low bulk density) and increase the consumption of water-absorbing resin (its have excellent water-absorbent and large bulk density), the ratio of water-absorbing resin in absorbing structure is improved.Thus, realize the purpose of sanitary material slimming and do not reduced water regain.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of water-retaining agent, have good water-absorbent.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of water-retaining agent is characterized in that: the component by following parts by weight forms: 5 parts of starch, and 10 parts of hydrophilic fibres, 10 parts of water absorbing resin particles, 5 parts of four jiaos of oxide powder and zincs absorb auxiliary agent 20-30 part.
Aforementioned water absorbing resin particle is that the cross-linked polymer of monomer that comprises vinylformic acid or acrylate is erose pulverized particles after by further surface-crosslinked processing.
Aforementioned absorption auxiliary agent is that sodium hydroxide solution is added the reaction of the former powder of guar gum, then adds initiator for reaction and then lowers the temperature and obtain.
The weight ratio of the former powder of aforementioned guar gum and described sodium hydroxide is 1: 8.
Aforementioned initiator is ammonium persulphate.
Usefulness of the present invention is: a kind of water-retaining agent provided by the invention, have good water-absorbent, and can significantly improve the absorbency that adding of water-retaining agent depress, and the absorbency under the with no pressure is without any reduction.
