Description
Technical field
The present invention relates to field of thin film fabrication field, and in particular to a kind of preparation technology of high-low temperature resistant PE heat sealable lid films.
Background technology
PE, complete entitled Polyethylene, it is the most widely used macromolecular material diaphragm in the world today.Usual feelings
Under condition, the difference according to density can be divided into high density polyethylene (HDPE) diaphragm, medium density polyethylene and low density polyethylene (LDPE).PE properties
Softness, adhesive performance is good, the characteristic with excellent resistance to most of lives and chemicals for industrial use.PE film application field bags
Include：Stainless steel plate, aluminium sheet, aluminium alloy extrusions, plastic-steel section bar and door and window, aluminium-plastic panel, decoration panel, poly (methyl methacrylate) plate etc..
At present, also there are some shortcomings in PE films：Such as to the less stable of heat, toughness is poor；Poor impact resistance；In outdoor
Under strong ultraviolet radiation, strength retention is low.
The content of the invention
In order to solve the above technical problems, the present invention provides the preparation work of a kind of high-low temperature resistant and PE heat sealable lid films with low cost
Skill.
Above-mentioned purpose of the invention is achieved by the following scheme：
A kind of preparation technology of high-low temperature resistant PE heat sealable lid films, comprises the following steps：
A, blending
By polyethylene LDPE 2426H, linear polyethylene LLDPE7042, metallocene MDPE1520 and polyethylene LDPE
LC7A is mixed, and incorporation time is 10~60 minutes；
B, masking
Production is filmed using PE casting machines；
C, extrusion
It is the polyethylene of 0.93 ± 0.05g/cm3 by density, is extruded through being cast the flat film mouthful gap of extruder, film mouthful slit width
It is 1.5mm to spend；
D, cooling
After through drawing-off roller stretching, chill roll is produced into temperature and nano-silicon rubber roll production temperature is adjusted to 14-16 DEG C, embossing
Shaping roller temperature production temperature is adjusted to 28 DEG C -30 DEG C.
Above-mentioned steps a polyethylene LDPE 2426H, linear polyethylene LLDPE7042, metallocene MDPE1520 and polyethylene
The mass percent of LDPE LC7A is respectively 30~30%, 40~60%, 5~20%, 10~20%.
The mass percent of polyethylene LDPE 2426H, linear polyethylene LLDPE7042 and metallocene MDPE1520 enters one
Step is preferably 25%, 50%, 10%, 15%.

The production temperature of above-mentioned steps b maskings is 195-220 DEG C.
The production temperature of above-mentioned steps c extrusions is 195-220 DEG C.
Compared with prior art, the device have the advantages that being：
Rationally, combination process is simple, and the addition of polyethylene LDPE LC7A can improve mixture and produce for inventive formulation
Mobility in journey, also effectively reduces the use ratio of polyethylene LDPE 2426H, so as to save cost.Add cyclopentadienyl gold
Category MDPE1520 can effectively improve puncture resistance and improve heat sealability.The present invention by optimizing preparation technology, particularly
The production temperature of each technique, it is ensured that obtained PE films have good temperature stability, while having good uvioresistant
Performance, experiment proves that strength retention was more than 90% in ultraviolet strong illumination 72 hours.
