Description

A kind of Black stretch film and preparation method thereof
Technical field
The present invention relates to winding technical field of membrane, and in particular to a kind of Black stretch film and preparation method thereof.
Background technology
Film is wound, is called stretched film, heat shrink films, the country is earliest with PVC (polyvinyl chloride) for base material, DOA (adipic acids two Monooctyl ester) produce PVC for plasticizer and a self-adhesion and wind film.Due to environmental issue, of high cost (with respect to PE (polyethylene) proportion Greatly, unit packaging area is few), the reason such as draftability difference, when 1994~nineteen ninety-five, the country started to produce PE stretched films progressively by Eliminate.PE stretched films are before this with EVA (ethylene-vinyl acetate copolymer) for self adhesive material, but its is of high cost, and flavoursome, after Development is self adhesive material with PIB (polyisobutene), VLDPE (very low density polyethylene), and base material is now (linear low close with LLDPE Spend polyethylene) based on, including C4, C6, C8 and metallocene PE (MPE).
Black stretch film belongs to one kind in winding film, i.e., black master batch is added during film preparation is wound and is made.At present Black stretch film need to store 30 days right and lefts mostly from producing to using can have certain viscosity, and viscosify masterbatch in producing Additive amount is also larger, causes cost accordingly to increase, and often many customer requirements shorter delivery cycle and higher cost performance. Therefore, it is necessary to the Black stretch membrane preparation method that a kind of cost is low, sticky release is fast.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of Black stretch film and its preparation side Method, has the advantage that cost is low, the sticky release of Black stretch film is fast.
One of the technical solution adopted by the present invention to solve the technical problems is：
A kind of Black stretch film, the raw material of the Black stretch film according to the mass fraction, including：Linear low density polyethylene (LLDPE) 37~99.6 parts, 0~50 part of metallocene linear-low density polyethylene (MLLDPE), 0.2~10 part of black master batch, increases Viscous 0.2~10 part of masterbatch, 0~30 part of reworked material；Wherein described black master batch according to the mass fraction, including：Polyethylene (PE) 40 ~70 parts, 20~55 parts of carbon black, 5~30 parts of the Tissuemat E of the equal relative molecular mass 1000~4000 of number；Wherein described thickening Masterbatch according to the mass fraction, including：40~70 parts of polyethylene (PE), 30~60 parts of polyisobutene (PIB).
In one embodiment：The black master batch does not contain slipping agent or opening agent.
In one embodiment：The slipping agent or opening agent are the slipping agent or opening agent of soap salt.
In one embodiment：The slipping agent or opening agent of the soap salt are zinc stearate or calcium stearate.
In one embodiment：The reworked material is to wind the leftover pieces produced during film preparation.
The two of the technical solution adopted by the present invention to solve the technical problems are：
The preparation method of above-mentioned Black stretch film, including：
1) raw material is uniformly mixed, obtains mixture；
2) mixture for obtaining step 1) uses tape-casting, is film-made 170~290 DEG C of temperature, chill-roll temperature 15 ~35 DEG C, by control speed than for 1.01~1.2 to ensure suitable winding tension, to obtain the final product the Black stretch film.
In one embodiment：In the step 2), 180~270 DEG C of temperature, 20~30 DEG C of chill-roll temperature are film-made.
Compared with background technology, it has the following advantages that the technical program：
1. black master batch is free of slipping agent or opening agent, and carrier polyethylene is homologous series, and it is female not interfere with thickening substantially The viscosity and rate of release of material, have certain viscosity after effectively ensure that winding film production, and preferably viscosity effect is can reach in 7 days Fruit, substantially reduces production and service life；
2. since the influence that black master batch is influenced to viscosity is greatly lowered, the additive amount for viscosifying masterbatch is also reduced accordingly, Coordinate the recycling of reworked material, therefore greatly reduce total cost of production, also mitigate environmental pressure；
3. preparation method of the present invention is easy, low, good control is required to production equipment, is adapted to continuous production.
