AI Technical Summary
Existing materials that change color with heat/temperature and humidity revert quickly to their original color when the influencing factors are removed, leading to rapid and often misleading color changes, which hinders precise observation and intended applications.
A new material is developed by adding an insulating material to the existing formula or coating it with an insulating layer, allowing the material to maintain color changes stably for a desired period under the influence of sunlight, darkness, water, heat/temperature, and humidity.
The insulating material slows down color change processes, extending the observation period and preventing misleading results, thus enabling more accurate monitoring and control of environmental conditions.
Description
[0001] A NEW MATERIAL THAT CAN CHANGE COLOR WITH HEAT / TEMPERATURE AND HUMIDITY AND THE PRODUCTION METHOD OF THIS MATERIAL
[0002] Field of the Invention
[0003] The invention relates to a new product / material obtained by adding an insulating material to the existing formula / manufacture of a product / material and / or by coating the product / material with an insulating material, which can change colour under the influence of sunlight, darkness, water, heat / temperature, humidity and / or various combinations thereof, in order to maintain the changed colour stably for a desired period of time, and to production methods of such product / material.
[0004] State of the art
[0005] A material that shows sensitivity to temperature and humidity conditions is called thermochromic or hygrometric. Thermochromic materials have the ability to change color in response to temperature changes. That is, for example, while these materials take on one color in cold weather conditions, they can turn into a different color in hot weather conditions. Hygrometric materials, on the other hand, can change their color tone by reacting to changes in humidity. For example, when the humidity rate increases, the material can turn into a darker color, while when the humidity rate decreases, it can turn into lighter colors. Hydrothermochromic materials change their colors in response to both temperature and humidity changes. For example, hydrothermochromic paints can show a marked change in color when humidity changes or wetness increases. Such materials are often used to play with visual effects or to signal thermal change. Such materials can be used to provide various warnings or indications to customers in applications where temperature and humidity are controlled. It can also be used to create interesting and innovative designs in fields such as fashion, decoration or art. The properties of all these materials that can change color with heat / temperature and humidity make them a practical and aesthetic alternative in various application areas.
[0006] Materials that change colour with heat / temperature and humidity generally return to their old colours quickly, because the effects of these factors are short-lived and easy to revert. When the heat / temperature or humidity source that caused the colour change is removed, such materials usually return to their original colour within a few minutes. The speed at which it returns to its original colour may depend on the structure of the material, the dye or pigments used, and the intensity of external factors. Materials that provide more permanent colour change can often have a slower turnaround time. The rapid colour transformation of materials with heat / temperature and humidity changes does not allow for various intended applications (traceability and measurement, etc.). The rapid colour change of these materials when away from target heat / temperature and humidity causes misleading results. The products in the state of the art cannot be used for the intended purposes due to rapid colour transformation.
[0007] Today, paints and materials that change colour with temperature and humidity changes offer solutions to meet different needs in almost all sectors. One of these solutions is the invention that is the subject of the utility model application numbered TR 2017 / 00258 and titled "Decorative Fence and Wire Mesh Systems that Change Colour with Heat, Light, Water and / or Emit Light in the Dark". The invention is a panel fence and / or wire mesh system for decorative purposes, characterised in that it comprises grass-like appendages dyed or mixed with at least one or more of colour changing with heat (thermochromic), colour changing in sunlight (photochromic), emitting light in the dark (photoluminescent) and colour changing with water (hydrochromic) masterbatch dyes and is characterised by containing a plastic derivative coating which completely surrounds the wire and thus protects the wire from external influences, and which is dyed with or incorporated into at least one or more of colour changing with heat (thermochromic), colour changing in sunlight (photochromic), emitting light in the dark (photoluminescent) and colour changing with water (hydrochromic) masterbatch dyes.
[0008] Another study is the invention subject to the patent application numbered TR 2015 / 10335 and titled ‘Carpet that changes colour in heat / temperature and / or light and the method of production of the said carpet’. The invention relates to a method for the production of carpets which change colour in heat and / or light, comprising the steps of mixing thermochromic dye, photochromic dye and phosphor dye by means of a mixer; putting the mixture into the dye reservoir of a digital printing machine; transferring the selected pattern onto the carpet by means of the printing machine.
[0009] Another study is the invention that is the subject of the patent application numbered WO 2000 / 022395 and titled "Heating Device with a Colour-Changable Decorative Coated Surface". A heating medium, such as a cooking vessel, has an inner surface coating that includes a decoration that changes colour as a function of temperature. A decoration based on a heatable resin and a chemical that changes colour as a function of temperature is applied over a coating of fluorocarbon resin inside the container.
[0010] Another study is the invention that is the subject of the patent application numbered TR 2021 / 006658 and titled "Organic Refrigerator Pouch Structure That Shows Humidity Change". In particular, the invention relates to a pouch configuration comprising a main body formed by stitching the front surface and back surface, front surface and back surface made of terry cloth woven with 100% organic cotton yarn with a hollow surface structure, front surface and back surface along the seam line in order to ensure that food products such as fresh vegetables and fruits remain alive and fresh as the first day until they are consumed, a mouth part formed on the upper part of the main body to put and remove food products into the pouch structure, Strip area created with colour-changing functional yarn or printing dye on the front surface and / or back surface to inform the user about the humidity status of the pouch structure.
[0011] Although dyes that change colour under the influence of heat / temperature or humidity are used in many different areas, from textiles to kitchenware, from heaters to the construction industry, in the state of the art, the rapid colour changes of these materials prevent the precise and accurate observation of the humidity and temperature in the environment and cause misleading results. As a result, the existence of the need for a material that changes colour under the influence of heat / temperature and humidity change and maintains this colour for a long time, which eliminates the disadvantages of the existing technique, and the inadequacy of the existing solutions made it necessary to make a development in the relevant technical field.
