Abstract
A manufacturing method of a high-haze high-viscosity protective film is disclosed. The protective film is manufactured mainly by a three-layer co-extrusion manner, wherein an A layer comprises polypropylene and polyethylene which are blended, a B layer comprises polypropylene and polyethylene which are blended, and a C layer comprises blended polystyrene type elastomers. The method is characterized in that the polypropylene is adopted as a substrate, haze is formed through roughness of the raw material itself and diffuse reflection caused by incompatibility between the polypropylene and the polyethylene so as to avoid precipitation of small molecules, and the C layer is an adhesive layer, is blended through adopting a unique formula, and adsorbs based on static actions of the material itself. The protective film has high-temperature resistance, capability of being not liable to degum, high haze, high viscosity, and other functions. The protective film is high in surface haze, and therefore the protective film is especially easy to uncoil and is not liable to adhere during high-viscosity product manufacturing, and the protective film is particularly suitable for brightening films, light guide plates, steel plates, and other industries requiring high viscosity for adhesion.

Technical field
The present invention is relevant a kind of haze, and full-bodied protecting film is particularly suited for brightness enhancement film, light guide plate, steel plate etc.
Need the viscous industry that could fit of height.
Background technology
The highest viscous adhesive protecting film generally exists, and precipitation is many, or the little patch of viscosity does not goes up, or thickening is the most strict
Evil, causes with affixed object product stick together brokenly ring affixed object product.And good multi-product, such as brightness enhancement film, light guide plate etc. just has
The difference of reverse side, is the most all to distinguish with coloured protecting film, and such cost is high, and color masterbatch has little molecule to separate out wind
Danger, the protecting film of the present invention can substitute coloured protecting film with the protecting film of haze, such that it is able to distinguish positive and negative, and
And noresidue under the protecting film high temperature of present invention making, brilliant point is few, and viscosity stabilized, the surface of haze is conducive to pile.This
Bright protecting film, because Surface haze is higher, is very easy to uncoiling when making the viscous product of height, it is not easy to adhesion.
Summary of the invention
The present invention solves the problems referred to above, it is provided that a kind of haze, full-bodied protecting film.
Technical scheme is summarized as follows
A kind of haze height glues protecting film and is mainly fabricated in the way of three-layer co-extruded, wherein A composition of layer be polypropylene and

Preferably, described a kind of haze height glues protecting film, and the polypropylene elastic modelling quantity of random copolymerization is at 800MPA-
Between 1200MPA.Fat melting is between 5-8.
Preferably, described a kind of haze height glues protecting film, the density of polyethylene from high pressure process 0.920-0.930 it
Between, fat melting is between 5-7.
Preferably, described a kind of haze height glues protecting film, and in B layer, polyacrylic ratio is at 80%-100%, poly-
Ethylene is 0%-20%.
Preferably, described a kind of haze height glues protecting film, and the elastomer of C strata phenylethylene, mainly with polyphenyl
Ethylene-butylene, polystyrene-pentadiene, Petropols, antioxidant mixing is made.
Preferably, described a kind of haze height glues protecting film, and the composition manufactured by the mixing of C layer is about polyphenyl second
Alkene-butadiene 20%-30%, polystyrene-pentadiene 40%-60%, Petropols 10%-30%, antioxidant 1%-3%.
Preferably, described a kind of haze height glues protecting film, and it is 10%-40%, B layer that A layer accounts for the ratio of whole film
The ratio accounting for whole film is ratio 5%-20% that 30%-60%, C layer accounts for whole film.
Beneficial effects of the present invention:
The protecting film mist degree that the present invention makes relies primarily on the roughness of raw material itself, and polyethylene with polyacrylic not
The diffuse-reflectance that the compatibility causes forms mist degree, is different from other principles (such as by adding matt master), and so make is excellent
Gesture is to avoid the precipitation of little molecule.
The protecting film that the present invention makes is mainly with polypropylene as base material so that the heat resistance of film is superior, it is easy to follow-up mould
Cut.
The protecting film C layer that the present invention makes is viscous layer, is depended on by the electrostatic of raw material own and is different from coating technique and makes
Protecting film, such advantage is film no solvent residue, will not degumming.
C layer viscous layer of the present invention, uses unique formula to be blended, by styrene-butadiene, polystyrene-pentadiene, stone
Oleoresin, antioxidant mixing is made, and hydrogenation degree is than traditional polystyrene-fourth preferentially to select polystyrene-pentadiene advantage to be
Diene (SEBS) is high, and such unsaturated double-bond is little, and the product made is viscosity stabilized, viscosifies little.Add antioxidant and make product
Ageing resistace be improved, extend the use cycle of product with period of storage.Add tackifying resin and make the soft of product
Changing point to improve, the mobility of increase product is with processability, and improves the viscosity of product.
The protecting film that the present invention makes causes film to compare mist because top layer is coarse, can produce other advantage, and film is solving
During volume, the best uncoiling, glues product scope at height especially, often as adhesion coating is with tegillum adhesion, causes film to be difficult to uncoiling.
