Abstract
The present invention is a kind of thermally adherent polymer film, its raw material consists of, the multipolymer 85-94% (weight) that has polar group, oxidation inhibitor 0.6-1.5% (weight), inorganic Synergist S-421 95 5-10% (weight), pigment dyestuff 0.1-0.8% (weight), static inhibitor 0.1-1.0% (weight), other Synergist S-421 95 0.1-4.0% (weight).This film has good thermal caking performance and heat sealability, is applicable to most of metallic substance and polarity non-metallic material heat posted compoundly, is widely used in the fields such as comprehensive shielded sheath of packing, anticorrosion, electric wire and cable.
Description
The invention belongs to a kind of polymer film, particularly relate to a kind of thermally adherent polymer film.
Present widely used polyethylene, polyvinyl chloride film does not all have the cohesiveness with other material, when needs bondings compound (promptly laminating), generally need film and bonded base material are made corona treatment respectively, make it the surface polarization, and carry out compoiste adhering behind the coated with adhesive again, so cohesiveness is not good enough, and operational path is loaded down with trivial details, the production cost height.
The objective of the invention is in order to solve above-mentioned shortcoming, a kind of film that can directly carry out thermal caking with most of metallic substance and polarity non-metallic material is provided.
The material component proportioning of thermal caking film of the present invention is, the multipolymer 85-94%(weight that has polar group), oxidation inhibitor 0.6-1.5%(weight), inorganic Synergist S-421 95 5-10%(weight), pigment dyestuff 0.1-0.8%(weight), static inhibitor 0.1-4.0%(weight).Other Synergist S-421 95 0.1-4.0%(weight).
The multipolymer that has polar group described in the present invention is general normal to be ethylene/acrylic acid copolymer (EAA), the ethene/acrylic ester multipolymer, also can be ethylene/methacrylic acid (EMMA), ethylene/vinyl acetate multipolymer (EVA) waits other to have the multipolymer of polar group.
Oxidation inhibitor described in the present invention is general normal to be phenolic antioxidant, as 2,6 ditertbutylparacresols.2,2-methylene bis (4-methyl-6 tertiary butyl) phenol, 4, two (the 6-tertiary butyl 3 methyl) phenol of 4-sulfuration, styrenated phenol etc.; Or amine antioxidants, as DNP(nitrogen nitrogen 2-β-benzene naphthalene Ursol D), DTTD(nitrogen ammonia 2 diphenyl-para-phenylene diamines), pyridyl-naphthalidine etc.; Or the ester kind antioxidant, defend at least a in tetrol ester, β-propionic acid octadecanol ester, sulfuration dipropionic acid two lauryls etc. as the four seasons.
Inorganic Synergist S-421 95 described in the present invention is general normal to be calcium carbonate powders, calcium sulphate powders, talcum powder, and SiO 2 powder, titanium dioxide, calcinated argil etc. or its mixture, granularity is advisable with 20-50m μ.
Pigment dyestuff described in the present invention general normal be the titanium cyanines, a kind of in thioindigo, anthraquinone, pyrene tetracid, dioxazines, the acid junket etc.
Static inhibitor described in the present invention general normal be amphoteric substance, as two property tetrahydroglyoxalines etc.
Other Synergist S-421 95 described in the present invention is generally coupling agent; as methyl-silicone oil, vinyltriethoxysilane (A-151); titanic acid ester such as vinyl three (2-methoxyethoxy) silane silane series coupling agents such as (A-172) and isopropyl triisostearoyl titanate are a kind of in the coupling agent; also can be to be total to its properties-correcting agent, as anti copper agent, anti-aging agent, fire retardant, anti UV agent etc.
When using the various additive beyond the above-mentioned resin, can directly add, also can be earlier and new LDPE (film grade) or as interpolation again after the mixed with resin granulation of base-material.
Thermal caking film of the present invention is a blown film, earlier various components is mixed by a certain percentage, is blow molded into the film that thickness is 0.05mm through the extrusion-blown modling unit then.
The mechanical property and the adhesiveproperties of thermal caking film of the present invention are as shown in table 1.
