Silicone rubber cable: comparison of four commonly used cable flame retardants

First, antimony flame retardant advantages: antimony trioxide can not be used alone as a flame retardant, and with the appropriate halogen compounds compound use, you can play a particularly effective flame retardant properties. Antimony system flame retardant co-efficient mechanism disadvantages: heavy metals, toxic, and arsenic homologue, crude products generally contain arsenic and other heavy metals, arsenic trioxide is arsenic. Can not be used as green filler and green flame retardant. Second, aluminum hydroxide flame retardant (ATH) Advantages: low price, good flame retardancy; Disadvantages: poor heat resistance, 200 ℃ that is the beginning of dehydration, 330 ℃ to 350 ℃ that is completely dehydrated, and the curing of the resin is more than in the aluminum hydroxide dehydration temperature range, thus leading to synthetic resins within the finished product foaming, surface unevenness, the dielectric properties of the decline in the yield is low. Used in high temperature leads to silica gel fogging, product white blistering, dielectric properties decline, etc. EC ≈ 60~100μS/cm, easy to absorb moisture. Third, magnesium hydroxide flame retardant advantages: application of magnesium hydroxide flame retardant (430 ℃ decomposition) non-toxic; disadvantages: not acid-resistant, acetic acid can dissolve magnesium hydroxide, only suitable for low-grade products. Easy to absorb moisture, poor dispersion, poor dielectric properties. Fourth, high heat-resistant Boehmite flame retardant (Boehmite, ALOOH) Advantages: 1% dehydration temperature of 350 ℃ or more, 500 ℃ dehydration to reach the peak, EC <50 μS/cm, dielectric, solving the aluminum hydroxide due to the dehydration temperature is low and lead to defects in the product and the problem of reduced dielectric properties, acid and alkali resistance; Disadvantages: Flame retardant is slightly lower than the aluminum hydroxide, to achieve the same fire-retardant properties More is needed to achieve the same flame retardant performance. However, it is characterized by high heat resistance, thermal conductivity, acid and alkali resistance, and the added value of the product can be improved by making it into high heat-resistant functional materials.
