Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Raw material is weighed according to following formulation weight percentage: random polypropylene 43%, polyolefin elastomer:
14%, C5 tackifying resin 4%, polyisobutene (PIB): 36%, PE wax: 2.5%, suffocated amine antioxidant weight accounts for 0.2%, nickel
It is that light stabilizer accounts for 0.3%.
Wherein:
Random polypropylene is used as the matrix resin of master batch, since it is amorphous polymer, to other compositions
There is good receiving to act on, can be improved the content of effective ingredient in master batch, reduce the additive amount of master batch, reduce the use of master batch
Cost, simultaneously because its amorphous structure, can reduce the crystallinity of film in the film production process, increase the bullet of film
Property.In the present invention, the melt index of random polypropylene preferably 50~100g/min.
The presence of POE elastomer can increase the compatibility between master batch matrix resin and film resin, reduce master batch addition
Influence to processing film stability.Its melt index preferably 10~30g/min.
C5 tackifying resin is the auxiliary agent that uses as the bonding force for increasing film, destroys the effect between macromolecule
Power increases its viscosity to reduce high molecular crystallinity.
Polyisobutene is used as main tackifier, and the two can increase the mobility of strand in film, thus
Make film that there is good viscoplasticity and preferable bonding force is presented.The number-average molecular weight of polyisobutene is preferred are as follows: 5~60,000.
PE wax used as lubricant and meanwhile also have certain plasticization, molecular weight be 20000~
50000, molecular weight is too low, is easy that the pollution caused to production equipment is precipitated, the excessively high then lubricant effect of molecular weight is deteriorated.
Key point of the invention, for main tackifier, and is carried out in the polyisobutene for using high molecular weight by a variety of tackifier
Compounding, since the molecular weight of polyisobutene is very high, will not generate precipitation phenomenon, in use so as to avoid protective film
On there is residue glue.Since polyisobutene is blocks, it is difficult to which directly the processing of progress twin-screw is granulated, and the present invention is by by its fritting
Melt and be re-fed into twin-screw granulation after the metering of metering pump 9 again, solves the processing difficulties of high molecular weight polyisobutylene.
Meanwhile the present invention has chosen the matrix that random polypropylene makees master batch, effective content for improving tackifier is reduced
A possibility that tackifier are precipitated, along with a variety of tackifier compounded technology with and extrusion plastic item chilling technique, effectively
Precipitation of the tackifier in master batch in production and storage is reduced, the final using effect of thickening master batch is improved.
Firstly, random polypropylene, POE, tackifying resin, PE wax, suffocated amine antioxidant, nickel system light stabilizer are by corresponding
Ratio is put into mixing device, carries out agitating mixing, and incorporation time 15min mixes revolving speed less than 100 revs/min.
Then, refering to fig. 1, raw material after mixing is put into powder hopper 1, is controlled under it by feed screw 2
Expect speed, it is sent on double screw extruder 3 according to a certain amount and carries out extruding pelletization.
The polyisobutene of high molecular weight is blocks, block-like polyisobutene is knocked down in melting tank 4, heating melting,
Heating melting temperature is 150~200 DEG C, and heating process needs logical nitrogen to be protected, and melting 4 top two sides of tank are respectively nitrogen
Entrance 5 and nitrogen outlet 6 beat feeding valve 7 after polyisobutene fusing, and polyisobutene enters receiver 8, then through metering pump 9 into
Row metering, is quantitatively sent in double screw extruder 3, by the measure control of feed screw 2 and metering pump 9, can flexibly adjust
The ratio for saving polyisobutene and other compositions is allowed to meet technique requirement.
Various components in twin-screw mixed melting be granulated, the temperature in each area of twin-screw be respectively as follows: 80~100 DEG C of an area,
Two 110~130 DEG C of areas, 120~145 DEG C of 3rd area, 140~155 DEG C of 4th area, 150~160 DEG C of 5th area, 155~175 DEG C of 6th area, machine
First 150~165 DEG C.
Finally, the plastic strip after squeezing out first passes through sink cooling of the water temperature lower than 15 DEG C, stop of the plastic strip in the sink
Time is greater than 0.5min, last pelletizing.
The present invention by selection have thickening plasticization effect auxiliary agent pre-production become plastic master batch, add the master batch with
Matrix resin carries out the production of film after being blended, can be produced by film manufacturing process such as traditional blow molding, curtain coatings in this way
Protective film product with preferable adhesion strength.Its simple production process, production procedure is short, and production cost is low, and production process is to ring
Border is pollution-free, has the preferable feature of environmental protection.
The present invention is protected with polyolefin blend extrusion again by the way that master batch is made in the auxiliary agent with Efficient Adhesive Promotion in advance
Film, production process are consistent with the production process of traditional films.
Protective film occurs small molecule precipitation in use or generates residue glue in order to prevent, and one aspect of the present invention passes through
Using random polypropylene as matrix, and increase POE as auxiliary, effective content for improving tackifier in master batch.Separately
Outer one side is then to select the polyisobutene of high molecular weight as main tackifier, by advance melting the polyisobutene of high molecular weight
It is sent into twin-screw after accurately being measured by metering pump 9 again after melting and enters processing, overcomes high molecular weight polyisobutylene and is difficult to
Directly carry out the difficult point of twin-screw extrusion processing.Simultaneously by the compounding of a variety of tackifier, and film bonding force can improved
While prevent it from residue glue occur on the surface of protected object body.In addition, being used lower when extrusion plastic item is cooling
Water temperature cooled down, so as to effectively reduce precipitation of the tackifier in production and storage in master batch, improve thickening master batch
Final using effect.
Finally, it should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although
Referring to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned
Technical solution documented by each embodiment is modified or equivalent replacement of some of the technical features, but it is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
Within the scope of.
