Abstract
The utility model discloses a kind of super drawing composite membrane, includes PVC film and PS films, it is characterised in that：Composite membrane is combined into by PU glue between PVC film and PS films.The utility model composite membrane is using PU glue to PVC film and PS Film laminateds, by improving the elongation of PVC film and middle PU bondline thickness being controlled, the PVC/PS composite membranes of super drawing when obtaining heating, the surfacing in compound KT plates, due to can super drawing into very thin PVC/PS composite membranes, so that the PVC/PS composite films cost of compound KT plates declines 50%, while composite membrane will not produce pin hole because of super drawing.
Description
Technical field
The utility model is related to PVC film technical field.
Background technology
The tensile property (elongation at break) of PVC film in the market is mutually on duty, normal temperature elongation be less than 5%, plus
Elongation percentage is less than 150% when hot.Though modified through increasing MBS etc., its normal temperature elongation is still less than 7%, and elongation percentage is small during heating
In 200%.Need to be restricted in the compound application of super drawing at some.For example：PVC/PS composite membranes, heat super drawing
Laminating KT plates.The stretching ratio of PVC/PS composite membranes depends primarily on the stretching ratio of PVC stiff sheet.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of super drawing composite membrane.
To solve the technical scheme that above-mentioned technical problem is used：A kind of super drawing composite membrane, include PVC film and
PS films, it is characterised in that：Composite membrane is combined into by PU glue between PVC film and PS films.
Further, the thickness of the PVC film is 0.04mm.
The thickness of the PS films is 0.06mm.
The spread 0.6-1g/m of the PU glue2。
The thickness of the composite membrane is 0.11mm.
The composite membrane normal temperature elongation at break is more than 30%, and draw ratio reaches 500% during heating stretching.
The beneficial effect brought using the utility model：The utility model composite membrane is using PU glue to PVC film and PS
Film laminated, by improving the elongation of PVC film and middle PU bondline thickness being controlled, super drawing when obtaining heating
PVC/PS composite membranes, the surfacing in compound KT plates, due to can super drawing into very thin PVC/PS composite membranes so that it is compound
The PVC/PS composite films cost of KT plates declines 50%, while composite membrane will not produce pin hole because of super drawing.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model super drawing composite membrane.
Embodiment
As shown in figure 1, a kind of super drawing composite membrane, includes PVC film 1 and PS films 2, in the utility model,
Composite membrane is combined into by PU glue 3 between PVC film 1 and PS films 2.
In PVC film production.Added in parts by weight in 100 parts of PVC in 0-5 parts MBS, 0-5 parts P83,0-5 parts of EMMA
One or more, then 0.8-2 parts of organotins, 1-2 parts of PA lubricants, 0.2-0.8 parts of G70 lubricants are added, in calendering processing
Extraction PVC film is carried out with less than 100% Lapie, PVC film of the extension at break more than 30% is obtained, thickness is 0.04mm.
Applied with above-mentioned PVC film wound membrane and scrape PU glue (spread 0.6-1g/m2), then pasted with thickness for 0.06mmPS films
Close, sizing winding obtains PVC/PS composite membranes, and thickness is 0.11mm, draw ratio reaches more than 500% during heating stretching.
In the compound KT plates of PVC/PS composite membranes heating, it is desirable to which the heating draw ratio of PVC/PS composite membranes reaches 400%
More than, the draw ratio after the existing PVC stiff sheet of in the market and PS are compound is less than 200%, and the stretching ratio of PVC/PS composite membranes
PVC stiff sheet is depended primarily on, PVC and glue used in PS compound tenses is scraped by improving the elongation of PVC stiff sheet and rationally applying, obtains
The PVC/PS composite membranes that high power more than 500% is stretched.
