Description
Technical field
The present invention is a kind of composite sheet hose construction, and more particularly to a kind of highlighted high-barrier cosmetics are aluminized composite sheet
Hose construction and preparation method thereof.
Background technology
The either domestic or external product of cosmetics in the market, packaging is multifarious, wherein directly wrapping
The plastic material of dress cosmetics has plastic bottle, plastic casing, polybag, coextruded plastic flexible pipe etc., because coextruded plastic flexible pipe is used
Raw material is few, cost is relatively low, by the development of more than ten years, has already taken up the main flow of Cosmetic Market, has been mainly used in face cleaning
Product, skin care item and cosmetology product etc..Although coextruded plastic flexible pipe is at present Cosmetic Market main flow, there is production effect
Rate is low, barrier and antioxidant difference shortcoming.
Chinese patent 201110308680.X, discloses a kind of colored translucent BOPET aluminizers, it is characterised in that it is wrapped
The former film layer of aluminium coated, colour-wash primary coat coating, BOPET is included, the thickness of BOPET original film layers is 12 microns, colour-wash bottom
Coating layer is located at the centre of aluminium coated and the former film layers of BOPET;The colored translucent BOPET aluminizers are by following manufacturer's legal systems
:The first step:BOPET original film selections:Select the former films of BOPET that thickness is 12 microns;Second step:At gilt coating
Reason:The red toner of 0.05% ratio and the yellow toner of 0.4% ratio are added into coating, be sufficiently mixed it is uniform after
On coating machine, the coating that solid content is 0.7~1.0 gram/m is carried out to former film corona surface using the anilox roll of 200 mesh, is applied
1 ± 0.2 micron of the thickness of coating after the completion of cloth;The red toner and yellow toner are the limited public affairs of the color skill metallic pigments in Zhongshan city
The serial toner of department, the coating machine is the model THG2100 of the vast Machinery Co., Ltd. in Wenzhou coating machine;3rd step:
The former films of the BOPET for gilt carrying out are inserted into vacuum aluminum-plating equipment, you can evaporation boat is opened and is preheated to equipment setting value
Between 70%~85%, aluminium wire transmission is then turned on, transfer rate is controlled between 180~450mm/min, starts equipment winding
To speed >=3.5m/s, open equipment baffle plate and start evaporation, aluminium steam, which is condensed to, cools down the BOPET that winding is not stopped on main hub surface
On the coated face of former film;Aluminum layer thickness according to measured by the device of on-line determination micro-coating thickness change of aluminizing thin film
Winding speed is adjusted, winding speed is controlled between 10.5~14.0m/s, the thickness control of aluminium coated is in the Ethylmercurichlorendimide of 75 Ethylmercurichlorendimides~85
Between, until the former film entire volume productions of BOPET are finished, shut down, cool down evaporation boat, vacuum pumping, open a position and unload film, detect thickness of aluminizing
Degree, product evaporation terminates.
