Abstract
The invention provides a complex black plastic film used for photosensitive material packaging, which is manufactured by using 60-80% of polyethylene, 10-20% of black masterbatch, 1-5% of diethyl phthaltate, 1-5% of aluminum stearate, 1-5% of trimethylammonium methyl sulfate and 1-5% of hexabromodiphenyl ether. The manufacture method comprises the steps of uniformly mixing the polyethylene granules and the black masterbatch in a mixing kettle, adding into an extruder and heating to 800 DEG C-1200 DEG C, adding other materials into the extruder and mixing, and extruding to obtain the final product. The complex black plastic film provided by the invention has the advantages of low cost and convenience for manufacturing and can be used as a packaging film for the photosensitive materials with the functions of light and moisture resistances as well as breakage resistance.
Description
Technical field
The invention belongs to field of packaging material, relate to a kind of black again plastic film that is used for the sensitive materials packing, the invention still further relates to this making method of black plastic film again.
Background technology
Lithographic film, offset plate material sensitive materialss such as (comprising PS version, CTP version) all need against sunshine, moistureproof wrapping material packing.At present, black mold can be satisfied its against sunshine, moistureproof effect, but it exposes intensity difference, cracky, and kraft paper commonly used can satisfy the requirement of pop strength, but it is against sunshine, moisture effect is not as black mold.So, produce both against sunshinely, moistureproof, the wrapping material of prevent breakage are very useful to the packing of sensitive materials again.
Summary of the invention
Technical problem to be solved by this invention provides the not only against sunshine but also moistureproof black again plastic film that is used for the sensitive materials packing of a kind of wrapping material that can make making, and technical problem to be solved by this invention also comprises this making method of black plastic film again.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is that the black again plastic film that is used for the sensitive materials packing that is designed is made up of following raw materials by weight percent:
Vilaterm 60-80%, black masterbatch 10-20%, diethyl phthalate 1-5%, StAl 1-5%, trimethyl ammonium methyl sulfate salt 1-5%, hexabromo phenyl ether 1-5%.
The present invention prepares again, and the method for black plastic film is:
Polyethylene pellet and black masterbatch are mixed in the batch mixing still, add be heated to 800 ℃-1200 ℃ in the forcing machine after, add other raw material again and in forcing machine, mix, extrude promptly and get.
In the used raw material of the present invention, Vilaterm is a high density polyethylene(HDPE), is the film forming main raw material, and it is good to have chemicalstability, characteristics such as corrosion-resistant, electrical insulating property, permeability rate are low.Black masterbatch, the main raw material of black plastic film, it is good to have chemicalstability, and anti-optical property is good.Diethyl phthalate is used to increase the plasticity of plastic film.StAl is the stablizer of plastic film, improves the stability of film.Trimethyl ammonium methyl sulfate salt is a kind of static inhibitor, can improve the insulativity of film.The hexabromo phenyl ether makes a kind of inhibitor, can improve the stability of film.
It is major ingredient with Vilaterm and black masterbatch that the present invention adopts technique scheme, adds the prepared black again plastic film of other raw material, the packing film that is applicable to sensitive materials that utilizes this black again plastic film to make, and existing against sunshine, dampproof effect has the function of prevent breakage again.The black again plastic film cost of the present invention's preparation is low, easy to make, and effective.
