The flame retardant of LCD is a material that can slow down or prevent the burning of substances under fire or high temperature conditions. Choosing the right flame retardant can improve the safety of the equipment and can meet the requirements of safety standards. In the manufacturing process of LCD, the commonly used flame retardants are as follows:
1. Flame retardant bromine compounds
Bromine compounds are currently one of the most widely used LCD flame retardants, they include isopropyl bromide, hexabromobiphenyl and dodecabromodiphenyl ether, etc. These compounds are mainly added to the substrate to achieve the purpose of flame retardant, the advantages of bromine compounds are good flame, retardant effect and lower cost, but the use of the process may produce environmental pollution and toxicity problems, so it has been banned in some countries.
2. Flame retardant phosphoric acid series compounds
LCD phosphoric acid series compounds such as trichlorophosphoric acid and triphenoxyphosphoric acid, etc., often used as a flame retardant LCD backplane materials, these compounds have thermal and oxidative stability, can be effective at high temperatures to play a role in flame retardant, but not as bromine compounds that produce pollution of the environment, and therefore are widely used.
3. Flame retardant nitrogen series compounds
LCD screen nitrogen series compounds such as polyurethane, epoxy aminotriphenol and intumescent polyurethane, etc., are also commonly used flame retardant LCD backplane materials, these compounds have good flame retardant properties and high-temperature performance, but in the price is relatively high, in addition, their scope of application still needs further research and development.
The selection of flame retardant materials for LCD mainly depends on the requirements of LCD application scenarios. Various factors, such as flame retardant performance, cost, environmental protection and production process, should be considered comprehensively in the selection process to ensure that safety is ensured while maintaining appropriate cost and market competitiveness.
