Flame retardant rubber is a flame retardant or flame retardant rubber, used in mine with rubber conveyor belt and a variety of rubber products. Common flame retardant rubber neoprene, silicone rubber and so on. At the same time, the use of fine reclaimed rubber and natural rubber and can also be used to produce flame retardant rubber, but in the production process and formula need to pay attention to many problems.
The use of fine reclaimed rubber and natural rubber production of flame-retardant rubber, we must pay attention to the following questions:
1, the amount of fine reclaimed rubber: The use of fine reclaimed rubber and natural rubber production of flame-retardant rubber, the amount of reclaimed rubber should not be too much to 100 parts of natural rubber as the base, fine reclaimed rubber added in the best 25-30;
2, choose the right flame retardant, a common flame retardant chlorinated paraffin and antimony trioxide combination, aluminum hydroxide, sodium borate, molybdenum oxide and tricresyl phosphate, etc., of which aluminum hydroxide, for example, In the choice must pay attention to its particle size, particle size is too large to affect production;
3, the production of different hardness of the fire-retardant rubber used in different filling materials, common filler materials are clay, white carbon black or calcium carbonate, if the flame retardant rubber hardness requirements of 40 degrees, the most suitable choice of calcium carbonate;
4, flame retardant rubber production formula, should not be added too much softening oil, otherwise it will affect the flame retardant rubber flame retardant products, the conditions permit the use of chlorinated paraffin oil as a formula softener;
5, the use of fine reclaimed rubber and natural rubber production of flame-retardant rubber, anti-aging system need to choose a good anti-aging antioxidant oxygen aging effect, such as antioxidant D, antioxidant RD and so on.
What should be paid attention to when using fine tire reclaimed rubber and using natural rubber to produce flame-retardant rubber?
