Description
Technical field
The present invention relates to pre-treatment water-based glue of a kind of vacuum aluminized film base material and preparation method thereof, belong to polymeric material field.
Background technology
Along with the development of packaging industry, there are again in recent years many new processing technology and purposes to be adopted widely.The aluminium plating film product reaches preferably barrier property because it is attractive in appearance, inexpensive, so that the aluminium plating film composite prod becomes the manufacturers' such as current food, medicine, makeup main flow packaged form already.But in the aluminium plating film actual production process, often occur aluminizing inhomogeneous, aluminium coated sticking power is low, and firmness is poor, easily comes off, and the problems such as aluminium coated migration often occur after compound with films such as PE, affects the quality of packed article.
In order to improve the production efficiency of aluminium plating film, Extrusion Coating is introduced in numerous packaging companies, because traditional vacuum aluminum-coated product is owing to adhesion strength between its aluminium coated and the film is lower, film can make the aluminium coated be full of cracks peel off under the high temperature, thereby causes the yield rate of product sharply to descend.Be the problem that the solution aluminium coated easily moves, external polyester film manufacturer also once attempted reaching enhancing aluminium lamination adhesion strength with the mode of coating processing.Some manufacturer carried out corona treatment to base material before aluminizing, after among the patent CN102248689A base material being carried out twice corona treatment, effectively improved the surface tension of film, further improve the sticking power of aluminium coated, but aluminum layer thickness can not surpass 350 dusts, after surpassing, the stripping strength of aluminized complex film will decline to a great extent.If can invent a kind of pre-treatment water-based glue of film substrate, as the base material of process corona treatment and the tackiness agent between the aluminium coated, can not only effectively improve the easily problem of migration of aluminium coated, can also increase the thickness of aluminium coated, further widen the suitable application area of aluminized complex film, improve the competitive power of this product in packaging industry, simultaneously the development of China's packaging industry also is significant.
