Description
Technical field
The invention belongs to field of adhesive technology, and in particular to a kind of high-stability type paper tube adhesive.
Background technique
Paper tube with good development and application prospects, can be used as the substitute of metal, glass, ceramic package container.With this
A little packing containers are compared, and paper tube packaging has apparent advantage, and be mainly characterized by: paper tube is using paper as primary raw material, at recycling
Reason is easy；It is odorless, nontoxic, safe and reliable, especially suitable for food packaging；It makes an uproar when can fill commodity of various shapes, and fill
Sound is small；Modeling structure multiplicity, outer layer can carry out color printing, have good display effect；Light weight, circulation is easy, easy to use,
Price is lower.The application field of paper tube is very extensive, can be used as chemical fibre industry pipe, thin film industry pipe, printing industry manage,
The pipe that paper industry pipe, metallurgical industry are managed, are packed in the every field such as pipe, thermometric paper tube, sampler paper tube.
Paper tube (paper tuber) is commonly called as paper tube adhesive, paper tube glue etc. with adhesive, is the various paper tubes of production, fiber drum, paper can
And a kind of special-purpose adhesive of related paper products.Each based article regards its purposes difference, has special requirement to paper tube adhesive.It is making
The POY type and low speed for making terylene station-service high speed spinning add play DTY type paper tube when, it is desirable that paper tube have sufficiently high compressive strength,
The good comprehensive performance such as hardness, toughness, water resistance, heat resistance and creep resistance.In fact, above-mentioned performance is to a great extent
Depending on the performance of paper tube adhesive used, i.e. paper tube adhesive needs to have following performance: good physical property, and milk freezes, nontoxic, nothing
Taste, Storage period are long.Good upper machine performance, kiss-coating is few, and tack is good, fast drying, the high preferable product properties of speed, and product is hard
Degree is high, and compressive resistance is high, water-fast, heat-resisting, creep resistant.The deformable sheet materials such as paper, cloth, plastic foil, metal foil are commonly used paper tube (paper tube)
It winds bundled, is made into paper tube core web-like finished product.These paper tubes are usually to roll volume, bonding with brown paper or other raw material paper machinery
It forms, binder used is known as paper tube glue.
With the rapid development of economy, requirement of the paper tube in daily necessities, weaving, light industry, packaging, leather etc. field is got over
Come bigger.Such as toiler roll inner core paper tube, Bobbin for spinning, cloth, paper product, leather, plastic film reel package paper tube
Etc..Traditional common paper tube (cylinder) glue mainly has gelatin, gelatinized starch (including oxidized starch and modified starch), polyvinyl alcohol
Formal liquid (107) adhesive, polyvinyl acetate emulsion (white glue with vinyl), PVA solution etc..Wherein gelatin, starch adhesive by
, storage period low in adhesive strength be short not to be used substantially；The disadvantage of polyvinyl alcohol adhesive maximum is exactly poor water resistance, and paper tube is resistance to
Compressive Strength increases sharp fall with the resting period, although part improvement can be obtained after acetalation, but still is not able to satisfy and wants
It asks；The water resistance of polyvinyl acetate emulsion will be good than preceding several adhesive, but initial bonding strength it is low, bonding after paper tube compressive resistance
It is its major defect with creep resistance difference.Develop the demand that novel paper tube adhesive meets market.
Paper tube adhesive to be used, mostly water dissolvable adhesive are led currently on the market, mainly by polyvinyl alcohol and cornstarch
Composition is had the disadvantage in that using such paper tube adhesive in the prior art on the one hand, due in winter, since temperature is lower, glue
Liquid can not assemble melting completely and form complete film, and become crack shape or powdery, so that the paper tube produced will produce
Raw " holding tube " phenomenon, the yield rate of paper tube are lower；On the other hand, the film-forming temperature as needed for such paper tube adhesive is higher,
Rate of drying is slower, during drying, phenomena such as be easy to causeing Product Variant, and and paper tube compression strength is low, is unable to satisfy client
Requirement, be unfavorable for the utilization and extention of the paper tube adhesive.
