Description
Technical field
The invention belongs to field of adhesive technology, in particular to a kind of express delivery plastic bag sealing pressure sensitive adhesive and its preparation side
Method.
Background technology
With the rapid development of e-commerce, every household has been come into shopping at network, and consumption security closes first as people
The problem of note, how to ensure purchase is the thing of self-selection, and the referred to as hotel owners and consumer such as guarantee cargo is not lost pay close attention to
The problem of.Ensure that courier bag has very high adhesion strength, make brokenly to restore soon, quick to bond, it is sealing to avoid switch accident
The technical problem that glue surface is faced.
, there is courier bag sealing market, common glue can only play sealing accordingly in a large amount of uses of plastics courier bag
Common bond effect, but bond loosely, and adhesive speed is slow, and packaging bag is easily opened, and is exchanged, is stolen so as to article occur
Surreptitiously accident, risk is brought to shopping at network.Hot-fusible pressure-sensitive adhesive except viscosity with variation of ambient temperature clearly, commercially available sealing
Glue is difficult to overcome the bond effect for remaining to keep good under winter cryogenic conditions, therefore pure scarce on the performance of product is stablized
Fall into.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency existing in the prior art, and provide a kind of with just viscous effect
Well, lower temperature resistance is good, adhesion strength is high, it is possible to achieve the quickly cohesive express delivery plastic bag sealing pressure sensitive adhesive and its system of courier bag
Preparation Method.
Technical solution is used by the present invention solves the above problems：A kind of express delivery plastic bag sealing pressure sensitive adhesive, its raw material
Including following component by weight percentage：
Naphthenic oil 4-8%；
White oil 8-12%；
Star-like SIS 12-18%；
S-B-S polymer 15-20%；
Polybutadiene 3-8%；
Styrenated terpene resins 8-12%；
Pentalyn 28-35%；
C5 Petropols 5-15%.
Isoprene content is 73-85% in the star-like SIS.
Butadiene content is 65-75% in the s-B-S polymer.
Preferably, the styrenated terpene resins softening point：100 ± 5 DEG C, color number：1-3 colors, melt at 150 DEG C
Melt-viscosity is 3000 ± 1000cps.
Preferably, the pentalyn softening point：95 ± 3 DEG C, color number：3-5 colors, ash content ＜ 0.1.
Preferably, C5 Petropols softening point >=115 DEG C, acid number ＜ 2mgKOH/g.
The preparation method of express delivery plastic bag sealing pressure sensitive adhesive of the present invention, it is characterised in that comprise the following steps that：
The first step：Stirred tank is warming up to 110 DEG C or so, is proportionally added into naphthenic oil with white oil；
Second step：Add star-like SIS (styrene-isoprene-phenylethene polymer）With styrene-butadiene-benzene second
Alkene polymer, control temperature are no more than 160 DEG C, and it is -0.1 ~ 0.5MPa to be evacuated to vacuum, stir to complete and melt；
3rd step：Stopping vacuumizes, and is then vented, and is proportionally added into C5 Petropols, styrenated terpene resins, pine
Fragrant pentaerythritol ester and PB, open vacuum valve and continue to vacuumize, and stir to complete and melt, keep the temperature 30 minutes；
4th step：Detect whether colloid melts completely after emptying, treat to melt completely, stop heating, treat that temperature is reduced to 120
DEG C, prepare plastic emitting；
5th step：Plastic emitting after inspection plastic emitting flow qualification.The present invention is the research and development that a kind of express delivery polybag divides mouth pressure sensitive adhesive
With preparation method.
Compared with prior art, the present invention haing the following advantages and effect：1st, glue is made to have well just using star-like SIS
Viscous effect, hub-and-spoke configuration glue is had good adhesion strength again, it can be achieved that the quickly bonding, while high-isoprene of courier bag
The star-like SIS of content can overcome cryogenic property very well, and SIS can increase the cohesive strength of glue well, after bond effect is realized
Ensure that glue will not destroy in itself；2nd, using phenylethene modified terpene resin can great reinfored glue polarity, increase and bond effect
Fruit；3rd, height is mixed into take advantage of a situation structure low molecular weight PB (polybutadiene）Equally there is good effect to lower temperature resistance, while knot of taking advantage of a situation
Structure can strengthen mobility；4th, employ the SIS of grafted maleic anhydride and the SIS of high PI contents is used in mixed way, add low temperature environment
Under still have terpene resin just viscous very well, make glue that there is the influence for remaining to overcome low temperature environment under the performance of high intensity, be presented 10
Stronger adhesion strength is rapidly achieved in second, tearing sealing just makes packaging bag damaged deformation；It is effectively viscous in the case of subzero 20 DEG C
The effect of knot.
