Abstract
The utility model relates to a polyester film with high transparency, including polyethylene glycol terephthalate layer, wearing layer, stratum lucidum and protective layer, polyethylene glycol terephthalate layer is connected to the wearing layer lower extreme, and the upper end of wearing layer is connected to the stratum lucidum lower extreme, and the lower extreme of protective layer is connected to the upper end of stratum lucidum, and the stratum lucidum material is polymethyl methacrylate material, and the protective layer is the polyurethane resin material. The utility model discloses simple structure, the transparency that the high transparency that utilizes polymethyl methacrylate material to have can effectual reinforcing polyester film, the effect is showing, the effectual low problem of polyester film transparency of having solved is favorable to improving polyester film's market rate of application, has improved enterprise production economic benefits.
Description
Technical Field
The utility model belongs to the technical field of the polyester film, concretely relates to polyester film with high transparency.
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 performing biaxial tension, the material is widely applied to the glass fiber reinforced plastic industry, the building material industry, the printing industry, the optical industry, the medical and health industry and the like, aiming at the glass fiber reinforced plastic industry or the optical industry, the material has high standard requirement on the transparency of the polyester film, the polyester film is a colorless transparent material and has certain transparency, but the transparency is reduced due to the addition of other composite materials in the process of processing a finished product, so the use range of the polyester film is directly influenced, the limitation of the polyester film is improved, and the production economic benefit of an enterprise is reduced.
Disclosure of Invention
The utility model aims at solving the defects and providing a polyester film with high transparency.
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 polyester film with high transparency comprises a polyethylene terephthalate layer, an abrasion-resistant layer, a transparent layer and a protective layer, wherein the lower end of the abrasion-resistant layer is connected with the polyethylene terephthalate layer, the lower end of the transparent layer is connected with the upper end of the abrasion-resistant layer, and the upper end of the transparent layer is connected with the lower end of the protective layer.
In a preferred embodiment of the present invention, the transparent layer is made of polymethyl methacrylate. The material has high transparency, the light transmittance can reach 96%, and the service cycle is long.
In a preferred embodiment of the present invention, the protective layer is made of a polyurethane resin material. The material has high strength and strong mechanical property, can effectively protect the surface of the polyester film, and has obvious effect.
The utility model has the advantages that: the transparent poly (methyl methacrylate) film has the advantages of simple structure, obvious effect, capability of effectively enhancing the transparency of the poly (ester) film by utilizing the high transparency of the poly (methyl methacrylate) material, capability of effectively solving the problem of low transparency of the poly (ester) film, contribution to improving the market application rate of the poly (ester) film and improvement on the production economic benefit of enterprises.
