Abstract
The utility model relates to a high strength is from type membrane, including polyethylene glycol terephthalate layer, anti-tear layer, wearing layer and enhancement core, the lower extreme on anti-tear layer is connected on polyethylene glycol terephthalate layer, and the upper end on anti-tear layer is connected to the lower extreme of wearing layer, and the setting of enhancement core upper end is inside the wearing layer, and the lower extreme extends to the inside on polyethylene glycol terephthalate layer, and the material on anti-tear layer is polycarbonate, and the material of strengthening the core is the carbon fiber, and quantity is three to five. The utility model discloses simple structure, polycarbonate material have high strength and coefficient of elasticity, high impact strength and good mechanical properties, intensity and tear resistance that can effectual reinforcing polyester film, and the effect is showing, and the high axial strength that carbon fiber itself had simultaneously is favorable to polyester film by extensive application in market, improves market economic benefits.
Description
Technical Field
The utility model belongs to the technical field of polyester film, concretely relates to high strength from type membrane.
Background
The polyester film is a film material which is prepared by using polyethylene terephthalate as a raw material, adopting an extrusion method to prepare a thick sheet and then carrying out biaxial tension, the material is applied to the glass fiber reinforced plastic industry, the building material industry, the printing industry, the medical and health industry and the like, but for the use of some special industries, the strength of the polyester film material on the market at present is far from sufficient, and the polyester film material is easy to tear due to insufficient strength, so that the market usability of the polyester film cannot be widely popularized.
Disclosure of Invention
The utility model aims at solving the above defects and providing a high-strength release film.
In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a high strength is from type membrane, includes polyethylene glycol terephthalate layer, anti-tear layer, wearing layer and strengthens the core, the lower extreme on anti-tear layer is connected on polyethylene glycol terephthalate layer, the upper end on anti-tear layer is connected to the lower extreme of wearing layer, strengthen the core upper end and set up inside the wearing layer, the inside on polyethylene glycol terephthalate layer is extended to the lower extreme.
In a preferred embodiment of the present invention, the material of the tear-resistant layer is polycarbonate. The material has high strength, good mechanical property and good stability.
In a preferred embodiment of the present invention, the material of the reinforcing core is carbon fiber, and the number of the reinforcing core is three to five. The material has high axial strength, strong impact resistance and long service cycle.
The utility model has the advantages that: simple structure, polycarbonate material have high strength and elastic coefficient, high impact strength and good mechanical properties, intensity and the tear resistance that can effectual reinforcing polyester film, and the effect is showing, and the high axial strength that carbon fiber itself has simultaneously guarantees polyester film's intensity further, is favorable to polyester film by extensive application in the market, improves market economic benefits.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
