The development of light-storage luminescent pigments (also known as self-luminous materials) marks that the era of traditional sulfides has passed, and the field of self-luminescence has entered a new era. The application fields of the new self-luminous materials are very extensive, mainly used in the fields of architectural decoration, transportation, military facilities, fire safety, daily necessities, etc., and have formed an industrial chain, and the domestic and foreign markets are very broad.
But in the early days of material development, many people did not fully understand its performance and were not interested in the products it made. Until the "9.11" incident in 2001, it played a huge role in enabling 18,000 people to escape. Self-luminous materials play a guiding role in emergency safety accidents, saving people a lot of time in the escape process and minimizing the rate of casualties. In 2001, the Ministry of Construction and the Ministry of Public Security jointly reviewed and approved the formal inclusion of the light-storage self-luminous evacuation indicator into the national "Code for Fire Protection Design of Buildings", "Code for Fire Protection Design of High-rise Civil Buildings", and "Code for Fire Protection Design of Civil Air Defense Engineering". Since 2002, provinces and cities across the country have successively promulgated fire protection design standards, and held standards implementation meetings to implement them. Since the application of self-luminous materials in the safety field is mandatory, the products made of luminescent pigments have attracted much attention, and are mainly used in ships, vehicles, subways, passages, and fire protection.
The application of self-luminous materials is divided into secondary products and tertiary products. The second-level product is a product made by directly applying luminescent materials, and the third-level product is a product made by further processing the second-level product. The second-level products include luminous film, luminous board, luminous ink, luminous paint, luminous plastic masterbatch, luminous chemical fiber, luminous enamel, luminous leather, etc .; the tertiary products include luminous signs, luminous crafts, luminous plastic products, luminous reflective enamel signs, Illuminated artificial flowers, illuminated toys, illuminated switches and buttons, etc.
Application of first and second level products
1. Luminous film, luminous leather, luminous board: mixed luminous material and organic resin to make luminous film, luminous leather. The luminous film is provided with stickers and release paper, which can be pasted freely and is easy to use; the luminous board is made by laminating the luminous film and the organic resin board. According to the use, it can be equipped with stickers and cut into various types Specification use.
The main performance is as follows:
â‘´ Products made of PVC plastic have certain flame retardant properties;
⑵ Has a certain resistance to salt water and detergent (can use detergent to clean);
⑶ It has excellent heat resistance and cold resistance, and can be used in the environment of -20 ℃ ～ 50 ℃.
â‘· Has good physical and mechanical properties.
2. Luminous ink, luminous paint, luminous paint, luminous printing paste: Mix the luminous material with transparent ink, paint, coating, and printing paste with dispersant and dustproof agent, and mix well before use.
After absorbing light in the bright place for 10min ~ 30min, it can emit light in the dark place for more than 12h, and its light absorption-luminescence-absorption function can be recycled indefinitely.
3. Luminous plastic masterbatch is to add high concentration of luminescent material to plastic particles, re-extrude and granulate to make universal masterbatch, and then add various plastics to make luminous products;
4. Luminescent chemical fiber is made by adding luminescent material to plastic particles and spinning to make luminescent fiber. [next]
Application of second and third level products
1. Luminous handicrafts, luminous artificial flowers, luminous toys are resin, glass and other products made by mixing luminous materials into various materials, and have high ornamental value.
2. Luminous plastic products, luminous switches and buttons are made by injection molding of luminous plastics.
3. The forms of luminous signs are various, including:
â‘´ The luminous film logo is to paste the printed pattern on the surface of the luminous film and use it on the wall;
⑵ Illuminated plate printed pattern logo, can be equipped with plastic injection frame and electroplated aluminum alloy frame to install on the wall surface according to actual needs;
(3) Self-luminous sign on the surface of the metal plate, a wall product made by spraying the metal surface and then screen printing;
â‘· Wall LED self-luminous products are mainly filled with luminous patterns on the panel, using LED as the excitation light source, when the power is turned off, the self-luminous patterns automatically emit light, and have higher brightness and more visual effect than non-powered signs;
⑸ Ground film label is a product that is printed on the surface of the luminous film after being abraded and printed to make the label stick on the ground;
⑹ The self-luminous indicator of Baigang is a ground indicator made by adding a self-luminous material to the surface of Baigang by a new process. It has the characteristics of beautiful and durable, flexible installation methods, etc .;
⑺ Self-luminous logo of tempered glass, a ground product made by printing a self-luminous pattern on the surface of tempered glass and then performing waterproof treatment, which has the characteristics of being resistant to dirt and easy to clean;
â‘» Ceramic self-luminous sign, the luminescent material and ceramic are sintered at high temperature into one, with high wear resistance and impact resistance;
⑼ Stairs anti-skid strip, a product filled with grooved stainless steel or copper strips with wear-resistant self-luminous materials, can be installed on the stairs as a safety indicator, and has a good application effect at night;
⑽ Ground LED self-luminous products. When powered, the LED is used as both an illumination indicator and an excitation light source for the self-luminous material. In the case of power off, the self-luminous pattern will use a high luminous brightness as an indicator. This form Product is a key item in fire protection products.
The above is a brief introduction to the application of luminescent materials. I believe that with the continuous development of technology, the application of luminescent materials will be more extensive.
