in the figure, the reference numerals are as follows, 1 denotes a film body, 2 denotes a base layer, 3 denotes a barrier layer, and 4 denotes a silicone oil layer.
Detailed Description
As figure 1, the utility model provides a self-adhesion is compound from type membrane for coiled material, including membrane body 1, supreme substrate layer 2, barrier layer 3, substrate layer 2, the silicon oil layer 4 of including at least are down followed to the membrane body, the material on silicon oil layer is waterborne silicone oil or oily silicone oil.
In some embodiments, the barrier layer has a thickness of 1 to 10 μm.
In some embodiments, the substrate layer has a thickness of 25 to 80 μm.
In some embodiments, the layer of silicone oil has a thickness of 0.3 to 1 μm.
In some embodiments, the material of the barrier layer is one of PVDC, PVA, EVOH, PA6, PET, modified nylon MX.
PVDC (polyvinylidene chloride) is a nontoxic, tasteless, safe and reliable material with high barrier property (barrier property refers to the permeation resistance to micromolecular gas, liquid and the like). The pure vinylidene chloride homopolymer has a structure of a head-to-tail linear polymer chain, has the characteristics of symmetry, high crystallinity, high density and the like, has strong intermolecular cohesion, and makes small molecules such as oxygen, water and the like difficult to move and pass through in PVDC molecules, thereby having excellent barrier property. The melting point of PVDC is 195-210 ℃, which is very close to the decomposition temperature (205-220 ℃), and the PVDC has poor compatibility with the common plasticizer, so the processing and molding are difficult. The PVDC is a copolymer polymer material mainly composed of vinylidene chloride.
PVA is polyvinyl alcohol, is a water-soluble crystal polymer generated by carrying out alcoholysis on polyvinyl acetate resin, has good biodegradability, gas barrier property, transparency, antistatic property, obdurability and organic solvent resistance, and has water solubility and biodegradability under certain conditions.
EVOH is an ethylene-vinyl alcohol copolymer having a higher gas barrier property than PA (polyamide), PE and PP and also higher gas barrier property than PVDC. EVOH is excellent in transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength, and also has high thermal stability, so that wastes produced during processing can be recycled.
PA6, nylon 6, is an important engineering plastic with excellent barrier properties, but has low melt strength and is difficult to blow mold directly. Laminar blending is one possible method.
PET is polyethylene terephthalate and is widely used in the field of packaging of foods, beverages, and the like. PET can prevent the permeation of oxygen, water vapor and carbon dioxide, and has the advantages of low cost, good gas barrier property and transparency, and good mechanical property.
The modified nylon MX, MX nylon, is made from m-xylylenediamine, and has excellent mechanical properties such as strength and elastic modulus, good processability, gas barrier properties superior to those of nylon 6 and nylon 66 and excellent oxygen permeability of 1/10-1/20, which is about that of the above-mentioned materials, compared with PET. It contains no halogen matter, produces no acid rain and dioxin polluting environment during combustion, can be recycled, can be used for food packaging, and also can be used as a gas barrier layer of films, plates and multilayer PET materials.
In some embodiments, the material of the substrate layer is one of polyester, polypropylene, polyethylene, and release paper.
The invention will be further elucidated with reference to specific embodiments.
