The synergistic effect of zinc borate

In the inorganic flame retardants, aluminum hydroxide flame retardant, smoke, filling three kinds of functions, because non-volatile, non-toxic, but also with a variety of substances produced synergistic effect, known as the inorganic pollution resistance flame retardants, but the use of aluminum hydroxide is usually necessary to add 50% (mass

Volume fraction) or more to show a good flame-retardant effect. Magnesium hydroxide and aluminum hydroxide in the case, this will add to the base resin due to the large deterioration of processability, mechanical properties losses. Antimony trioxide is an essential co-halogen flame retardant agent,

However, when used alone has little effect fire. Due to the higher zinc borate dehydration temperature (greater than 300 ℃), over most of the decomposition temperature of the polymer, antimony trioxide can be used in place of all or part of thermosetting polyester formulations, reduces the cost, but also

With aluminum hydroxide, magnesium hydroxide, and phosphorus-based flame retardants produce good synergistic effect, thereby reducing the amount of these additives, reducing their processing properties of the substrate.
In the study of zinc borate and magnesium hydroxide, aluminum hydroxide, antimony trioxide, chlorinated paraffin flame retardant in the low-density polyethylene Synergistion found zinc borate flame retardant flame retardant system with either complex or with the compound with halogen flame retardant system, can achieve good flame effect

Fruit, and reduce the amount of other flame retardants, to improve the processing properties of the material.
