Abstract
The present invention relates to a kind of polyester elastomer multi-function membrane and its forming method, is a kind of thermoplastic elastomer thin film.It is characterized in that by single screw extrusion machine peace seam mould extrusion film, being cast rotary drum through supercooled water or low temperature, rapidly cooling and shaping obtains TPEE cast films.Effect of the invention is that prepared by the method for extrusion a kind of has higher mechanical strength, heat-resisting quantity, lower temperature resistance and weatherability, the thin polymer film also with more preferable corrosion resistance and water resistance compared with traditional film.Equipment used is simple, and easy to implement and operation, is produced in existing general film molding equipment.It is widely used in the multiple fields such as building, medical, industrial goods, clothes, all kinds of joint products, packaging for foodstuff, advertisement film.
Description
Technical field
The present invention relates to multi-function membrane field, more particularly, to TPEE films and preparation method thereof.
Background technology
As thermoplastic elastomer (TPE) TPEE materials have the incomparable high intensity of other plastics and elastomeric material, high-ductility
The excellent specific property such as property, wear-resisting, oil resistant, cold-resistant, ageing-resistant, because of its special crystal phase structure and filiform molecular structure, possessing can
Recycling, degradable environmental-protecting performance, meet the carbon footprint requirement of the world, and TPEE can be applicable to every field.At present
TPEE films have widely been used all kinds of, civil and military field abroad, have very high technology and application level.
But because TPEE films have good elastic resilience, the thermoplasticity high compared with other glass transition temperatures
Plastics more easily cause phenomena such as " the quick-fried muscle " of film take-up process, " macula lutea ", and more seriously film is bonded in wrapup procedure
Together, cutting can not be unreeled, film is scrapped.TPEE films, elasticity is high, and film is softer, wind, unreel it is relatively difficult.
In the case of certain tension force, film is easily deformed, and can cause film " race side " in wrapup procedure.
The content of the invention
In view of problem present in background technology, it is an object of the invention to provide a kind of multifunctional polymer film and its
Preparation method, this method can solve the problems, such as that TPEE films can not unreel cutting in wrapup procedure, and by biaxial tension
Process poisoning film heating, is its relaxation is obtained bigger intensity and modulus.
To achieve these goals, the invention provides a kind of preparation method of polyester elastomer multi-function membrane, it is wrapped
Include step：
(1) TPEE particles are put into blowing-type drying box, 100-150 DEG C of dry 3-5h；
(2) dried TPEE particles are added in single screw extrusion machine, passes through flush joint formula mould extrusion film.
(3) film of extrusion is cast rotary drum rapidly cooling and shaping by cooling water or low temperature, obtains cast film.
(4) by casting films biaxial tension in a heated state, biaxially oriented film is obtained.
Beneficial effects of the present invention are as follows：
TPEE thin polymer films prepared by the present invention not only have higher mechanical strength, resistance to height compared with traditional film
Warm nature, lower temperature resistance and weatherability, also with more preferable corrosion resistance and water resistance.
Equipment used in the present invention is simple, and easy to implement and operation, is produced in existing general film molding equipment
.
The multi-functional TPEE films of the present invention can be widely applied to building, medical, industrial goods, clothes, all kinds of compound
The multiple fields such as product, packaging for foodstuff, advertisement film.
Hereinafter, the preparation method of the multi-functional thin polymer film of the present invention is illustrated in conjunction with specific embodiments.
Embodiment

(2) distance should be less than 5cm between film and the cooling water water surface or rotary drum.
(3) the curtain coating film thickness obtained is 0.1mm, and thickness is 0.05mm after biaxial tension at 100 DEG C.
Performance test
The measure of tensile strength and elongation at break
According to national standard《The measure of plastic tensile performance》(GB T1040.3-2006) third portion, film and thin slice
