Abstract
The invention relates to a rubber composite membrane and a method for preparing the same. The method comprises the following steps that: 92 to 98 percent of polypropylene resins, 1 to 1.5 percent of antistatic agent and 1 to 6.5 percent of antiblocking agent are uniformly mixed and measured; and the membrane is obtained after lengthwise stretching, transverse stretching and drawing through a single-screw extruder, physicochemical reaction and biaxial tension. Compared with the prior art, the rubber composite membrane is characterized by high tensile strength, good transparency and so on.
Description
Technical field
The present invention relates to a kind of film, relate in particular to a kind of glue composite membrane and preparation method thereof that has.
Background technology
It is a kind of very important flexible packing material that the glue composite membrane is arranged, and uses very extensive.Have the glue composite membrane colourless, do not have smell, tasteless, nontoxic, and have high tensile, shock strength, rigidity, obdurability and the good transparency.There is glue composite membrane surface energy low, need carries out corona treatment before gluing or the printing., the glue composite membrane is arranged after corona treatment, good printing adaptability is arranged, can chromaticity printing and obtain exquisite appearance effect, thereby be commonly used for the surface material of laminated film.
There is the glue composite membrane that deficiency is also arranged, as do not have heat sealability.In order to obtain the heat sealable glue composite membrane that has, can there be glue composite membrane surface corona to handle the heat sealable resin adhesive liquid of back coating, as PVDC latex, EVA latex etc., but also coating solvent glue also can adopt the method for extrusion coated or coextru-lamination to produce the heat sealable glue composite membrane that has.
Have the initiation tear strength of glue composite membrane to increase after stretching, but the secondary tear strength is very low, therefore, BOPP film both ends of the surface can not leave any otch, otherwise tear easily at printing, compound tense.Can produce ew Year pictures after glue composite membrane coating glue is arranged, be one of market that has glue composite membrane large usage quantity.
Summary of the invention
Purpose of the present invention be exactly a kind of high tensile, the good transparency be provided in order to overcome the defective that above-mentioned prior art exists glue composite membrane and preparation method thereof arranged.
Purpose of the present invention can be achieved through the following technical solutions: a kind of have a glue composite membrane, it is characterized in that this film comprises following component and content (weight percent):
Acrylic resin 92-98%,
Static inhibitor 1-1.5%,
Antiblocking agent 1-6.5%.
Described static inhibitor is selected from one or more in erucicamide, amine ethoxylate, the Tegin 55G amine hydroxybenzene.
Described antiblocking agent is selected from one or more in silicon-dioxide, silicon class, the organosilicon.
A kind of preparation method that the glue composite membrane is arranged, it is characterized in that, this method comprises following processing step: with acrylic resin 92-98%, static inhibitor 1-1.5%, antiblocking agent 1-6.5% is after mixing, metering, after physical-chemical reaction is carried out in single screw extrusion machine, longitudinal stretching, cross directional stretch and traction, obtain this film through two-way stretch.
Described screw rod expressing technique temperature is 200-270 ℃.
Compared with prior art, the present invention with the polypropylene be the high tensile of raw material, the good transparency the glue composite membrane arranged, this have the glue composite membrane with its good transparent packing that is widely used in bread, clothes, footgear etc., and the cover package of cigarette, books.
Embodiment
Below in conjunction with specific embodiment the glue composite membrane and preparation method thereof that has involved in the present invention is described.
In following examples, F280 represents: China Petrochemical Industry Company's product acrylic resin;
Static inhibitor is represented: Shanghai Jia Mo company product;
Antiblocking agent is represented: Shu Er Man product;
Acrylic resin, static inhibitor, antiblocking agent and Co-polypropylene through mixing, the metering after, after physical-chemical reaction is carried out in single screw extrusion machine, MDO, TDO and traction, get final product this film.Technological temperature is 200-270 ℃.
The gained film is made corresponding batten according to the ISO testing standard, tests under the dry state condition.I.e. conditions 24 hours in moisture eliminator is tested under 23 ± 2 ℃, the environment of 50 ± 5% relative humidity then.
According to ISO 1133 canonical measure melting index;
According to ISO 527 canonical measure tensile strengths;
Embodiment 1～3
