Description
Technical field
The present invention relates to a kind of degradable Adhesive composition and preparation method thereof, belong to degradation material and producing high-molecular
Work technical field.
Background technology
With the continuous development of industry, Organic adhesive has greatly application in every field, generally uses at present
Organic adhesive has isocyanates adhesive, polyurethanes adhesive, organic silicon adhesive, Epoxy adhesive, phenolic aldehyde
Resin adhesive etc..Because existing adhesive can produce pernicious gas either liquid during use, or it is viscous
It is bad to close effect, limits its application on environmental protection industry (epi).Further, since current adhesive does not all have degradability, because
Destruction of the adhesive of this residual to environment is very big, and urgent need wants a kind of environment-friendly degradable adhesive.
Degradable high polymer material mainly has PBAT, PLA, PHA, PPC etc., at present for degradable high polymer material
Exploitation prepares moulding etc. mainly on plastic products are prepared, such as prepare film, then several for its application on adhesive
Without reference to.PBAT will have very big application prospect due to itself possessing side chain and affinity group on adhesive.
The content of the invention
The shortcomings that in prior art, the invention provides a kind of adhesive of PBAT environment-friendly degradables.With good
Adhesive power and be able to can have extensively in packaging, electronics, office, artifacts, agricultural, food etc. with degradable
General application, especially there is very wide application prospect on disposable product.
The present invention is achieved by the following technical solutions：
In a first aspect, the invention provides a kind of degradable Adhesive composition, it includes counting in parts by weight as follows
Component：
Preferably, the degradable Adhesive composition includes the following component counted in parts by weight：
Preferably, the montmorillonite be by organic ammonium salt modified montmorillonoid, organic siloxane modified montmorillonite,
One or more in unmodified montmorillonite.Montmorillonite possesses lamellar structure, passes through organically-modified and screw rod shearing collective effect
Either individually screw rod shearing effect can cause its interlaminar separation, prepare the imvite modified PBAT materials of nano level sheet
Material.The addition and modification of montmorillonite can cause PBAT adhesives to possess better characteristics, on the one hand, due to montmorillonite possess it is tactile
Denaturation, can cause the preparation of adhesive more easily can more to be embodied with energy-conservation, the generation of nano-grade montmorillonite
This advantage；Second aspect, adhesive can be preferably molded after preparing；The third aspect, adhesive is in the process used
In, it can faster plastify after heating and be uniformly distributed on base layer, while cool down adhesive layer during bonding
Can uniformly it be distributed.Inventor also found that montmorillonite possesses well into nuclearity in research process simultaneously, be a kind of excellent
Nucleator, when realize nano-grade layering after, its additions can cause solidify after adhesive caking property it is stronger.Cover de-
The content of soil does not limit specifically, but in order that the adhesive that must be prepared possesses certain mechanical performance and bonded well
Property, selects the scope of montmorillonite between 0~30 part, preferably between 2~15 parts.
Preferably, the organics additive is selected from PLA, PPC, PBSA, PHA, PEF, PCF, ADR, sorbierite
One or more in derivative, organic pigment.The addition of high-molecular organic material can improve other property of PBAT adhesives
Can, such as hydrophobicity is improved, adhesive layer bending resistance, tear-resistant ability, deflection are improved, improves the gas resistance of adhesive layer
Every property etc., further, since PBAT has preferable dyeability, therefore the addition of suitable organic pigment can be prepared with difference
The adhesive product of color.Therefore the adhesive product with suitable performance can be prepared by adjusting different adding proportions.
Preferably, the inorganic filler is selected from nano-calcium carbonate, talcum powder, hydrotalcite, nano calcium oxide, nanometer
One or more in titanium dioxide, carbon black, mica, whiting, inorganic pigment.The addition of inorganic filler can reduce adhesive
Cost, while can be interacted with organic pigment, the adhesive of different colours be prepared, in addition also to the mechanicalness of adhesive
It can be strengthened.
Preferably, the crosslinking agent is cumyl peroxide (DCP).DCP can promote PBAT as crosslinking agent
Between cross-linking reaction either chemical reaction between PBAT and organic polymer, make generation network structure possess it is more excellent
Caking property.Because on the one hand on the other hand DCP can be also a kind of strong oxidizer, therefore to high score as the initiator of reaction
The structure and performance of sub- material have influenceed, therefore select 0~1 part of conduct suitably to add scope, more preferably 0~
0.3 part.
Second aspect, present invention also offers a kind of preparation method of degradable Adhesive composition as the aforementioned, it is wrapped
Include following steps：
PBAT resins, montmorillonite, crosslinking agent, organic polymer and inorganic filler are granulated, obtain masterbatch mix；
The masterbatch mix is subjected to extrusion molding, obtains the degradable Adhesive composition.
Prepared master batch is prepared into final adhesive product by being processed further.It can be made by twin-screw extrusion
Grain shaping, Single screw extrusion granulating and forming prepare particle shape adhesive, can apply on apertured products with adhesive, also may be used
To be used in normal pressing mold adhesion process；Thread adhesive can be prepared by spinning moulding, due to thread adhesive
Specific surface area is big, and filament diameter is small, therefore bond area can be improved in adhesion process, makes the intensity of bonding higher；Can be with
By injection molding, large-scale sheet jointing material is mainly prepared, applies the bonding in large parts；Blowing can be passed through
Shaping, prepares relatively thin binder film, applies in multilayer film fitting etc.；Thickness can be prepared by flow casting molding can
PBAT adhesive films are adjusted, have potential replacement effect for the adhesive film such as existing PVB, EVOH.
Preferably, the method for the shaping is granulating and forming, spinning moulding, injection molding, blow molding or stream
Prolong shaping.
The third aspect is thin in bonding polyimides present invention also offers a kind of degradable Adhesive composition as the aforementioned
Purposes in film.
Applicant has been surprisingly found that the adhesive prepared by the formula has for Kapton in actual production
Prominent cementitiousness.
Compared with prior art, the present invention has following beneficial effect：
1st, prepare and use during it is pollution-free；
2nd, the prepare and adhesive after use can be realized degradable；
3rd, it can be realized by adjusting formula and repeatedly used；
4th, there is unexpected bonding effect such as polyimides to many materials.
