Description
Technical field
The present invention relates to hygiene article sectors, in particular to interlabial pad individual labeling glue.
Background technique
Sanitary napkin is that women often uses one of amenities, and demand is big, and quality requirement is high, particularly, consumer for
The safety of the articles such as sanitary napkin and sanitation degree pay attention to day by day.Common sanitary towels packaging is mostly external whole big
Packaging, inside are equipped with a fairly large number of monolithic sanitary towels, and be in can be straight for all monolithic products after outer packaging is opened
The state used is connect, for the monolithic sanitary towels for failing to timely use, is tended to by pollution sources in external environment
Pollution, influence using.
Therefore, most products can also carry out independent packaging to every a piece of sanitary napkin in external big packaging currently on the market,
Thus ensured the normal use of monolithic product, and varied, the existing tearing mode that the opening ways of independent packaging are also the same
Also there is opening labeling type, opposite opening labeling type is more more environmentally-friendly, therefore applies more extensive.
Meanwhile the product of independent packaging is also more convenient to carry, and for the independent packaging of labeling type that is open, labeling
The adhesive property at place is then of crucial importance, and the adhesion strength of labeling and substrate can neither be too strong, to prevent from being difficult in time when opening
Raise, can not adhesion strength it is too weak, with prevent carry when cause edge warpage.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of interlabial pad individual labeling use
Glue has the effect of that caking property is strong and is easily peeled off.
Above-mentioned technical purpose of the invention technical scheme is that, a kind of interlabial pad individual mark
Patch glue, the component including following parts by weight: 38-60 parts of styrene analog thermoplastic elastomer；30-45 parts of tackifying resin；It is soft
10-15 parts of agent；1.5-2 parts of antioxidant.
By using above-mentioned technical proposal, there are unique two phase structures for styrene analog thermoplastic elastomer, itself is without viscous
Knot property improves wettability, cohesive force, peel strength and shear strength by tackifying resin and softening agent, increases initial bonding strength and holds
Long adhesive strength, the stickup for enabling to labeling glue stable use, and other components further improve whole performance, reach both
There can be certain adhesion strength to be easy to remove in time in independent packaging use again, be easy to use.
The further setting of the present invention are as follows: the styrene analog thermoplastic elastomer is SBS, the styrene analog thermoplastic
The melt index (MI) of elastomer is less than 10g/10min.
The further setting of the present invention are as follows: the tackifying resin is to pass through hydrotreated C5/C9 Petropols.
By using above-mentioned technical proposal, tackifying resin is to hydrogenate complete C5/C9 Petropols, of light color and nontoxic,
Meet medical requirement, thus be applied to amenities be also completely can with, and hydrogenated resin molecular link after hydrotreating
Stable double bond is formed, is easily saturated, chemical property is stablized, therefore non-aging；Thermoplastic elastomer (TPE) has longer strand
It is intermolecular not easy to break so that finished product made of hot-fusible pressure-sensitive adhesive is easily peelable with good elasticity, and good elasticity makes
Residual is seldom had after must removing, and can smoothly be torn when independent packaging enables.
The further setting of the present invention are as follows: the softening agent is naphthenic oil, and the antioxidant is phenol antiager.
By using above-mentioned technical proposal, the addition of softening agent can make trademark adhesive be easy to construct in low temperature.Antioxidant
Addition can assign trademark adhesive good antioxygenic property, increase trademark adhesive the preservation time and paste after label gluing knot
Intensity is held time.
The further setting of the present invention is to be prepared using following steps:
Step 1: according to parts by weight, weighing 10-20 parts of styrene analog thermoplastic elastomer, 30-45 parts of tackifying resin, phenylethylene
15-20 parts of thermoplastic elastomer (TPE), 10-15 parts of softening agent, 1.5-2 parts of antioxidant；
Step 2: reaction vessel being heated to 135-140 DEG C, softening agent is added and is stirred heating；
Step 3: antioxidant, the tackifying resin of 20wt% and the styrene analog thermoplastic elastomer of 20wt%, control reaction is added
Vessel temp is 145-150 DEG C until tackifying resin and styrene analog thermoplastic elastomer melting are complete；
Step 4: control reaction vessel temperature is 165-170 DEG C, and styrene analog thermoplastic elastomer, antioxidant, remaining is added
Tackifying resin and remaining styrene analog thermoplastic elastomer are reacted, reaction to styrene analog thermoplastic elastomer, thickening
Resin and styrene analog thermoplastic elastomer melting completely, form first product；
Step 5: stop stirring, after first product is stablized, discharging；
Step 6: filtering, cooling, packaging.
By using above-mentioned technical proposal, main component is divided into front and back and is added twice, and is added for the first time on a small quantity, the
Secondary investment main component component, using this kind of seedage feeding mode, first is that a small amount of component is first allowed to have in the reaction vessel
There is a space for being sufficiently mixed and reacting, and keep being heated evenly that consistency is higher as far as possible, so as to steady promotion each component
Between reaction, then put into second of reacting dose again, incremental participation reaction reacts complete between guarantee each component as far as possible
It is complete abundant.
The further setting of the present invention are as follows: the melting of tackifying resin and styrene analog thermoplastic elastomer in the step 3
Shi Changwei 15-18min, styrene analog thermoplastic elastomer, tackifying resin and styrene analog thermoplastic elastomer in the step 4
Melting when a length of 38-45min.
By using above-mentioned technical proposal, each component reaction sufficiently, and makes the finished product glue being prepared after interacting
Body does not have penetrating odor, and colorless and transparent, while softening point can reach 70-80 DEG C, the tool in subsequent be applied on substrate
There is good mobility, it is higher for the applicability of substrate, it can be a variety of substrates such as non-woven fabrics, PE film or PVC base, just
Qualified labeling is obtained in coated and molded.
The further setting of the present invention are as follows: antioxidant, tackifying resin and styrene analog thermoplastic bullet is being added in the step 3
Property body after vacuumized again full of nitrogen, styrene analog thermoplastic elastomer, tackifying resin and phenylethylene is being added in the step 4
It is vacuumized again after thermoplastic elastomer (TPE) full of nitrogen；The vacuumize process make in reaction vessel air pressure be -0.1~-
0.5Mpa。
By using above-mentioned technical proposal, directly vacuumizing can cause still to have in reaction vessel because vacuum degree is inadequate
Vapor residual.And nitrogen is first full of in reaction vessel, make the vapor of nitrogen discharge reaction vessel, then vacuumized.
Remaining in reaction vessel at this time is nitrogen.And nitrogen is inert gas, compared to for vapor for product substantially without shadow
It rings.
The further setting of the present invention are as follows: when discharging in the S5, discharge port is heated, keeps discharge port temperature
Degree is 155 DEG C -162 DEG C, is forced into 0.1-0.15MPa, and step 6 is filtered using 120 mesh screens.
By using above-mentioned technical proposal, heating is carried out to discharge port and guarantees that colloid products smoothly flow out, and sieve
Setting can also timely be filtered out to complete constituent monomers are had neither part nor lot in, and promote the total quality of finished product pressure sensitive adhesive.
In conclusion the invention has the following advantages: can either have certain adhesion strength to be easy in independence again
Packaging is removed in time when using, and is easy to use；The environment-protecting and non-poisonous colorless and odorless of component used simultaneously, receiving degree are higher.
