Description

Technical Field

[0001] The invention relates to the technical field of films, and in particular to a privacy and stain-resistant bathroom film and a manufacturing method thereof. Background Art

[0002] Nowadays, almost every household has a shower room. Hospitals, hotels, schools and other public places are also equipped with shower rooms. The partitions of shower rooms are basically made of glass, usually tempered glass. Although tempered glass is not easy to burst, it is not completely safe, because the current tempered glass cannot reach a 100% explosion-proof rate, and there is a certain probability of bursting, especially when the temperature is relatively high during bathing, and the glass is not well heated, and there is a hidden danger of bursting, especially in winter. In addition, because the surface of the glass is extremely not resistant to stains, it is easy to form water marks and residues, affecting the beauty of the environment. Furthermore, shower rooms are mostly private, but the transparency of the glass does not have the function of protecting privacy. In summary, the safety, privacy, and stain resistance of the shower glass room are currently very urgent for people to improve. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a privacy and stain-resistant bathroom film and a method for making the same. By pasting the explosion-proof film of the present invention on the shower room glass, its safety, stain resistance and privacy can be improved to meet people's living needs, especially for the installed shower room, there is no need to change or replace any facilities, only the privacy and stain-resistant bathroom film of the present invention needs to be added, which is simple to operate and low in cost.

[0028] Figure 1 It is a schematic diagram of the finished product structure of the privacy and stain-resistant bathroom film of the present invention. DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present invention. It should be understood that the following description is only used to explain the present invention and is not intended to limit the present invention.

[0030] As used herein, the terms "comprises," "including," "having," "containing," or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises the listed elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

[0031] The conjunction "consisting of excludes any unspecified element, step, or component. If used in a claim, this phrase renders the claim closed-ended so that it does not include materials other than those described, except for conventional impurities associated therewith. When the phrase "consisting of" appears in a clause of the body of a claim rather than immediately following the subject matter, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0032] When amount, concentration or other value or parameter is expressed as range, preferred range or a series of upper preferred value and lower preferred value limit range, this should be understood as specifically disclosing all ranges formed by any pairing of any range upper limit or preferred value and any range lower limit or preferred value, regardless of whether the range is disclosed separately. For example, when disclosing range "1 to 5", described range should be interpreted as including range "1 to 4", "1 to 3", "1 to 2", "1 to 2 and 4 to 5", "1 to 3 and 5" etc. When numerical range is described in this article, unless otherwise stated, the range is intended to include its end value and all integers and fractions within the range.

[0033] Singular forms include plural references unless the context clearly indicates otherwise. "Optional" or "either" means that the subsequently described event or incident may or may not occur, and that the description includes instances where the event occurs and instances where it does not.

[0034] Approximate terms in the specification and claims are used to modify quantities, indicating that the present invention is not limited to the specific quantity, but also includes acceptable and modified parts close to the quantity without causing changes in the relevant basic functions. Accordingly, the use of "about", "approximately", etc. to modify a numerical value means that the present invention is not limited to the exact numerical value. In some examples, the approximate terms may correspond to the accuracy of the instrument for measuring the numerical value. In the specification and claims of this application, range limitations can be combined and / or interchanged, and if not otherwise stated, these ranges include all subranges contained therein.

[0035] The indefinite articles "a" and "an" before the elements or components of the present invention have no limitation on the quantity requirements (i.e. the number of occurrences) of the elements or components. Therefore, "a" or "an" should be interpreted as including one or at least one, and the elements or components in the singular form also include the plural form, unless the quantity obviously refers to the singular form only.

[0036] In addition, the descriptions of the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" described below mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the technical features involved in the various embodiments of the present invention can be combined with each other as long as they do not conflict with each other.

[0053] The light transmittance, haze, water drop angle and privacy of the finished products obtained in the above embodiments and comparative examples were tested, and the results are shown in the following table.

[0054]

[0055] Note: The more ★ there are, the higher the shielding ability is.

[0056] Haze: The ratio of the scattered light flux that deviates from the direction of the incident light through the sample to the transmitted light flux is expressed as a percentage, which is the haze. Samples with large haze will give people a more blurred feeling.

[0057] Transmittance: Light will be lost when passing through the sample. The ratio of the transmitted light flux through the sample to the incident light flux irradiating the sample, expressed as a percentage, is the transmittance.

[0058] Water drop angle: the angle between the gas-liquid interface and the solid-liquid interface at the interface of solid, liquid and gas. A small water drop angle indicates a large surface tension and the surface is easy to stick; a large water drop angle indicates a small surface tension, poor surface adhesion and good anti-fouling effect.

[0059] It will be easily understood by those skilled in the art that the above description is merely an example of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
