Description
Technical field
The present invention relates to spill-preventive breast pad technical field, specifically a kind of spill-preventive breast pad tailored version water-absorbent resin surfaces change
Property method.
Background technique
Water-absorbing resin is that a kind of compound with more hydrophilic radical is solid netted by having for crosslinking formation
The polymer of structure can absorb itself tens times or even thousands of times of substance and be answered extensively because it is with excellent property
For fields such as physiological hygiene, agricultural, building, medicament slow release, daily light industries.In physiological hygiene, water-absorbing resin is in water swelling
Soft hydrogel is formed afterwards, sense of discomfort is not had after use, will not be generated stimulation to human skin, will not be generated inflammation, because
This can be applied to the fields such as baby paper diaper, incontinence piece, female sanitary towel；Agriculturally, a certain amount of suction is added in the soil
Water-resin can reinforce the water holding capacity of soil and reduce moisture evaporation, reinforce the stability of soil, can be applied to desert transformation
It is given treatment to drought；In building, water-absorbing resin may be used as sealing, water proof, humidity regulation material in construction material；Medicament slow release
On, water-absorbing resin is fabricated to tubular container, can be put into organism, drug can be discharged in specified position, to cancer
The therapeutic effect of disease is obvious；On daily light industry, because the slow releasing function of water-absorbing resin and suction-operated, can be applied to cosmetics
In additive, thickener, the dehydrating agent etc. in food.With the gradually expansion of its application range, demand also increases year by year
Add, becomes the research hotspot of numerous scientific research personnel.
Currently, acrylic acid series water-absorbing resin is most widely used, but such water-absorbing resin has absorption speed slower, product
It is easily agglomerating tacky, influence the normal use of product.In the market, the synthesis of water-absorbing resin generally mainly using water solution polymerization process and
Via Inverse-Phase Suspension Polymerization obtains the water-absorbing resin of high water absorption multiplying power or haline water multiplying power.But in the practical application of water-absorbing resin
The moisture in air is easily absorbed there are raw material, bonding is agglomerating, and liquid permeability is poor, and moisture is difficult internally to permeate, to cause suction
Substantially reducing for speed is received, its use value is affected, especially in this highly viscous non-newtonian fluid of lotion, water-absorbing resin
Logical fluidity and dispersibility to improve water-absorbing resin absorption speed it is most important.Otherwise it is agglomerating serious to will lead to appearance, it can not
The phenomenon that use.Therefore it is modified surface to be carried out to water-absorbing resin, so that water-absorbent resin surfaces have certain hydrophobic grouping, is formed
A kind of gradient-structure gradually decreased from particle surface to internal crosslinking degree, so that moisture is able to quickly penetrate into inside resin,
It in order to which hydrone is quickly and inside water-absorbing resin, and then is contacted with hydrophilic radical, to improve the liquid permeability and dispersion of product
Property, so that product there can be faster absorbing emulsions speed in the biggish non-newtonian fluid of viscosity, improve the practical value of product
And commercial value, reduce cost.
Summary of the invention
The present invention in order to overcome the deficiencies of the prior art, provides a kind of spill-preventive breast pad tailored version modifying surface of absorption resin side
Method can quickly absorb lotion, absorbing emulsions ability with higher, preferable gel strength, logical fluidity, dispersibility, water conservation
The absorbing material of the high comprehensive performance of property.
To achieve the above object, a kind of spill-preventive breast pad tailored version method for modifying surface of absorption resin is designed, it is characterised in that:
The specific method is as follows:
(1) dispersing agent is sprayed onto water-absorbent resin surfaces, under 500-800 revs/min of mixing speed, so that water suction tree
Rouge is fully dispersed not to unite；
(2) inorganic crosslinking agent, organic crosslinking agent are dissolved into deionized water by the deionized water for weighing a certain amount of room temperature
In, it sufficiently dissolves, to shorten wakeup time, improves infiltration rate, a small amount of surfactant is added and is made into treatment fluid；
(3) treatment fluid is uniformly sprayed on water absorbing resin particle, is stirred；
(4) water-absorbing resin handled well is put into stainless steel disc, is reacted at a certain temperature certain time, that is, complete to inhale
The surface of water-resin is modified；Reaction temperature is 120-180 DEG C, and the reaction time is 60-90 minutes.
The dispersing agent is ethyl alcohol.
The inorganic crosslinking agent is aluminum sulfate.
The organic crosslinking agent is polyethylene glycol 400 double methacrylate (PEG400DA), ethylene glycol diglycidylether
(EGDE)。
The surfactant is Tween 80.
The dispersing agent accounts for the 5-80% of water-absorbing resin gross mass.
The inorganic crosslinking agent accounts for the 0.1-10% of water-absorbing resin gross mass.
Polyethylene glycol 400 double methacrylate (PEG400DA) in the organic crosslinking agent accounts for water-absorbing resin gross mass
0.01-5%；Ethylene glycol diglycidylether (EGDE) accounts for the 0.1-15% of water-absorbing resin gross mass.
The surfactant accounts for the 0.001-1% of water-absorbing resin gross mass.
The treatment fluid accounts for the 1-200% of water-absorbing resin gross mass.
The present invention compared with the existing technology, can quickly absorb lotion, and absorbing emulsions ability with higher is preferable solidifying
The absorbing material of the high comprehensive performance of glue intensity, logical fluidity, dispersibility, water-retaining property.Compared with existing product on the market, this
The water-absorbing resin 1min absorbing emulsions amount that method was modified can achieve 49.4g/g, have preferable absorbing emulsions speed, and inhale
Time receiving is well dispersed, will not be agglomerating, therefore has preferable practical value and commercial value.
