Description

Composite type smooth master batch and production technique thereof that a kind of BOPP film is used
Technical field
The invention belongs to the functional agent and the technology thereof of plastics film, specifically be meant the composite type smooth master batch and the production technique thereof of a kind of BOPP film (that is: BiOriented Polypropylene Films) production usefulness.
Background technology
The BOPP film is a kind of very important flexible packing material; Since have colourless, do not have smell, tasteless, nontoxic characteristics and high tensile, high impact, toughness is strong; Good characteristics such as optical property, so at packaging field application is very widely arranged, its market is also in continuous expansion.The present BOPP film yield of China reaches 2,500,000 tons/year, has twenties BOPP film lines to put into production approximately to the end of the year 2009 in 2008, and the YO of following BOPP film will reach 3,000,000 tons/year.But; In the BOPP film prodn process, the friction that resin and equipment room exist had both reduced Resin Flow, had increased energy consumption again; And reduced the stability of resin owing to frictional heat; BOPP film itself does not have smooth property, but the BOPP film is applied to wrapping material, generally needs certain smooth property.Therefore can solve through in resin, adding slipping agent usually.Modern plastics processing just develops towards robotization, high speed and high-qualityization direction, and the BOPP foil production speed is fast more, easy more friction and produce static, and easier adhesion between the film seriously hinders high linear speed to extrude; The transparency that film requires is good more, and it is high more to produce mold temperature, easier conglomeration, adhesion.
The mechanism of action of slipping agent: be exactly the uncompatibility of utilizing between slipping agent and the polymkeric substance; Behind the BOPP film forming, slipping agent is moved to the surface in film, builds up into uniform shallow layer; Make film surface smooth; Thereby significantly reduced the frictional coefficient of BOPP film surface, changed the balance between BOPP film sliding and the resistance to blocking, made the BOPP film have good smooth effect.
At present generally being used in the surface slip agent commonly used on the BOPP film, generally is to use erucicamide or silicone separately, and wherein silicone is liquid, adds and uses inconvenience, and cost an arm and a leg, and is difficult to apply at home; Erucicamide is a kind of BOPP film slipping agent that relatively is suitable for, but it has considerable influence to the mist degree of film.
For slipping agent can be dispersed in the thin film layer in BOPP film prodn process, slipping agent generally adds with the form of masterbatch.Slipping agent and masterbatch carrier Vestolen PP 7052 thorough mixing are after twin screw extruder is extruded, smooth masterbatch is processed in dry, pelletizing; Again masterbatch ratio is on request added in the BOPP film prodn raw material; Through the BOPP film line extrude, two-way stretch, will move and be evenly distributed to the BOPP film surface through surface slip agent after certain timeliness.Home-made increases smooth masterbatch at present, and surface slip agent content is generally 7～8%, and the addition (weight ratio) that is used on the BOPP film is about 2～4%, because addition is more, it is totally higher to add cost.
Summary of the invention
For overcome existing BOPP film surface slip agent existing use inconvenient, cost an arm and a leg, be difficult to applying or the mist degree of film is had considerable influence; And slipping agent content is low, addition is more, add the overall higher defective of cost; The purpose of this invention is to provide composite type smooth master batch and production technique thereof that a kind of improved BOPP film is used, can overcome the defective of prior art.
The technical solution adopted for the present invention to solve the technical problems is:
The composite type smooth master batch that a kind of BOPP film is used is characterized in that: be made up of following component and content (weight part) thereof:
Vestolen PP 7052 80～90
Composite type smooth agent 10～20
The preferable content (weight part) of technique scheme is:
Vestolen PP 7052 80～85
Composite type smooth agent 15～20
The recombiner of erucicamide and polyolefin amide is preferably adopted in the composite type smooth agent of technique scheme, and compositely proportional (weight part) can be:
Erucicamide 5～15
Polyolefin amide 10～30
The polyolefin amide of technique scheme preferably adopts SEPIGEL 305, polybutylenes acid amides etc.
The production technique of the composite type smooth master batch that a kind of BOPP film is used; It is characterized in that: use precision weighing system batching; Composite type smooth agent and carrier Vestolen PP 7052 thorough mixing after twin screw extruder with melt extrusion; Forcing machine production temperature is controlled at 215～225 ℃, current control at 440～460mA, and the forcing machine revolution is controlled at 420～430r/min, and head pressure is controlled at 18～20MPa/h; Melt temperature is controlled at 220～230 ℃, and melt extrusion is after drying, cooling, pelletizing form the masterbatch finished product.
Beneficial effect of the present invention: owing to contain slipping agent up to 10～20% in the masterbatch, addition can be reduced to 0.5～2%, so improved the unit product added value, significantly reduces production, manufacturing, transportation cost and finally is converted into the final use cost of reduction client.Because slipping agent adopts the composite type smooth agent, has good smooth effect so both guaranteed the BOPP film, has guaranteed that again the BOPP film has good transparency; It is ingenious compound particularly to adopt erucicamide with good smooth effect and the polyolefin amide with good transparency to carry out, and makes under the not high situation of price, obtains the preferable net effect of good smooth effect and transparency.The present invention is the modern technique scheme of the higher efficient smooth master batch of a kind of cost performance of few additive, is suitable for applying.
Below in conjunction with embodiment the present invention is done to describe more specifically.
