What is the application of aluminum hydroxide flame retardant?
Everybody knowsaluminum hydroxideThe advantage of flame retardant is very obvious, then, it is used in what industry.
1. Unsaturated polyester
Unsaturated polyester can be used to make a variety of high-voltage or low-voltage electrical switches, which add alumina, you can make the product has a certain flame retardant, smoke and arc resistance. Because high whitealuminum hydroxideThe whiteness of more than 93%, and polyester resin has a very similar refractive index, so in recent years, domestic and foreign countries will use polyester resin and aluminum hydroxide to make new decorative materials, that is, artificial agate.
2. Epoxy resin
The role of aluminum hydroxide in epoxy resin is to increase the oxygen index. For example, if 100 parts of epoxy resin are selected and 80 parts of aluminum hydroxide are added, the oxygen index will change from the original 20.0 to 27.5. The main function of epoxy resin added with aluminum hydroxide is to be used for sealing materials, casting parts, epoxy resin glass fiber sheets, etc. The epoxy resin filled with aluminum hydroxide can also make transformers, insulation equipment, switchgear, etc., and has a good future.
3. Thermoplastics
Among the thermoplastics, polyvinyl chloride is common, and aluminum hydroxide can very easily be incorporated into plasticized polyvinyl chloride instead of calcium carbonate. Using this, you can achieve a high standard of flame retardancy, one is the use of aluminum hydroxide and phosphate plasticizers, the other is the use of aluminum hydroxide and zinc borate, these two formulations can be used in PVC wire, cable material. In short, the addition of high-filling aluminum hydroxide in plastic products, on the one hand, can play a flame retardant effect, and through the new surface treatment technology, improve the tensile strength and impact resistance of the product, can be widely used in electrical conduits and equipment jackets.
4. Synthetic rubber
Aluminum hydroxide added in rubber, can be used as a flame retardant for styrene butadiene rubber latex foam rubber and carpet bottom rubber adhesive, can also be used for bedding with neoprene.
As can be seen,aluminum hydroxideThe application of flame retardants is very extensive and plays an important role in many industries, bringing very good results.
