Abstract
The invention discloses a kind of menses absorbing materials, in the material preparation process, the oil phase that will be made of first acrylic ester monomer, crosslinking agent, emulsifier and assistant for emulsifying agent, with the water phase being made of electrolyte solution and sodium acrylate solution, and by initiator solution carry out emulsification w/o type High Internal Phase Emulsion is made.Then it by emulsion coating on the base material being made of non-woven cloth and covering another layer of non-woven cloth, and is made up of high-temperature steam solidification, washing, drying and other steps.The material both has the good sense of touch of esters of acrylic acid foamed material and high magnification absorbent properties, it can overcome that esters of acrylic acid foam industry metaplasia production bad mechanical property, absorption rate is low, can not absorb caking haemocyte and larger physiological tissue, the defects of pressure amount of bleeding back is high again, be provided simultaneously with better economy.
Description

The existing amenities for the purpose of absorbing menses such as sanitary napkin, panty liner, underpants for woman in period, mostly use greatly with
The absorber that wood pulp cellulose, polymeric absorbent resin are separately formed or form in hybrid form, it is bad to wear next to the skin comfort,
Phenomena such as being susceptible to conglomeration, hardening in use.
In view of menses absorb the requirement that amenities is worn next to the skin, softness, the porous absorbent foam of frivolous ventilative are obvious
It is a kind of more preferably absorbing structure form；More research team is being explored using acrylic monomer as raw material, polymerization synthesis one kind
Continuous type foamed material with efficient absorption ability；Domestic outer portion team has been achieved with major progress, example in this field
The patent as disclosed in 2007.03.14 " prepares foamed material " by High Internal Phase Emulsion（Eric's P Granbergs et al.,
CN1930222A）, patent " water-absorbing acrylic ester foamed material and its preparation method and application " disclosed in 2014.07.23（Woods
Gorgeous sweet smell, CN103936918A）, patent " high internal phase emulsion foam associated with polyurethane foam " disclosed in 2017.05.10
（The small Elbert Hubbards of WM, CN106659816A）Deng referring to using acrylic ester monomer as primary raw material, by phase in height
Emulsion template method prepares porous absorbent foamed material, is applied to menses and absorbs hygiene article sector.
But it published is prepared now using acrylic ester monomer as primary raw material, by High Internal Phase Emulsion template
Foamed material, there is following obvious shortcoming：

Difference causes the liquid absorption in amenities actually uses relatively low, and same basis weight materials are to the absorption of menses simulant liquid
Time index and be more than containing one times of water absorbing polymer particle absorbing material or more to physiological saline soak time index；
Third, menses constituent is complex, has both included free haemocyte, also include gather blocking haemocyte and
Other physiological tissues, it has been disclosed that foamed material have certain absorption to free haemocyte, however because do not have fibre
The architectural characteristic of dimension property material can not absorb the haemocyte of caking and larger physiological tissue, can only be allowed to be adsorbed on material
Surface cannot sufficiently achieve the absorption requirement of menses absorbent article；
4th, for present published foamed material when being under pressure extruding, the amount of bleeding back is higher.
Therefore, technique improvement is carried out to the existing technology for preparing acrylic foam based on High Internal Phase Emulsion template,
Developing a kind of can give full play to esters of acrylic acid foamed material soft texture and the high good characteristic of absorbency and overcome
Foam industry metaplasia production bad mechanical property, absorption rate is low, can not absorb caking haemocyte and larger physiological tissue, pressure
The defects of amount of bleeding back is high, the novel menses absorbing material for being provided simultaneously with more preferable economy are of great significance.
