Description

Anti-fog film

The present invention is a light transmissive film, in particular a light transmissive antifogging film which prevents the generation of mist.

When a car passes through a long tunnel and enters an indoor (usually an underground parking lot), the rear view mirror often has fogging due to temperature difference and moisture, which seriously affects the driving sight. When it rains, the raindrops will adhere to the surface of the glass and the mirror, which will affect the driving sight due to the raindrops. There are many anti-fog methods available on the market. It is more convenient to spray an anti-fog film to temporarily prevent the generation of fog, but the effect is not significant. Anti-fog treatment uses hydrophilic treatment technology to achieve surface anti-fog effect, preventing water droplets like fog from condensing on the surface, which is commonly used in the field of optics, such as lenses and lenses for cameras, goggles or telescopes. In addition, when riding a locomotive, the fog will be attached to the helmet windshield lens due to the hot air exhaled by the human body, which will also affect the driving line of sight. Some anti-fog methods are coated with a layer of anti-fog film. This way, due to the smooth plane of the light-transmitting material, the adhesion is deteriorated and it is easy to fall off. The hot air/steam generated during bathing will stick to the mirror, causing troubles when using the mirror after bathing, such as shaving, blowing hair, skin care products, etc. Although the common bath mirror products on the market have additional defogging devices, they are in a humid environment for a long time, and the electrical appliances are dangerous due to the humid environment. When the dentist performs treatment, a special dental mirror is used to observe the affected area. While the patient is breathing, the surface of the dental mirror is attached to the mirror at the front end, which affects the observation of the doctor. In addition, the doctor will wear a mask when the knife is opened to ensure that the infection is caused by the patient's mouth foam or wound blood during the operation. The mask is disposable, and the surface of the mask will be due to the heat generated by the doctor's own breathing. The fog is attached, which affects the line of sight when the knife is opened. Therefore, how to solve the above problems and shortcomings in the past, that is, the creators of the creation and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the creators of this creation have collected relevant information, and have designed and developed such new patents through continuous evaluation and modification through multi-party evaluation and consideration, and through years of experience in the industry. The main purpose of the present invention is to provide an anti-fog film comprising: a base film for penetrating all visible light waves and having a front side and a back side; an anti-fog layer being a hydrophilic chemical layer uniformly coated on a protective film is disposed on a plane of the anti-fog layer such that the anti-fog layer is located between the base film and the protective film; and a backing adheres to the reverse surface of the base film to allow the base film to be repeatedly pasted On the surface of any object. In a preferred embodiment, the anti-fog layer is a chemical layer containing ultraviolet light blocking. In a preferred embodiment, the anti-fog layer incorporates an agent that increases the hardness of the coating. In a preferred embodiment, the base film is a PET (Polyethylene Terephthalate) optical film or a polycarbonate (PC) optical film. In a preferred embodiment, the backing is a bismuth compound. In a preferred embodiment, the adhesive is an acrylic adhesive. In a preferred embodiment, the adhesive is dried, cured and adhered to the reverse side by ultraviolet light. In a preferred embodiment, the anti-fog film exhibits a planar geometry that is applied to the object. In a preferred embodiment, a PET release film is further coated on one of the planes of the backing, such that the backing is between the base film and the PET release film. This creation has the characteristics of a hydrophilic coating that reduces the exposure of raindrops to the surface of the glass and mirror when it rains, which affects the line of sight. In addition, because the temperature difference and moisture cause the rear view mirror to fog, which seriously affects the driving sight, this creation can completely eliminate this phenomenon. In addition, the anti-fog film of the present invention has any planar geometry and can be attached to any object, so the anti-fog film can be freely cut into any shape, and is not limited to use on a plane of any shape. The above described objects, features, and advantages of the present invention will become more apparent from the written description.
